Allis-Chalmers Tractor Plant

Ever wonder what the Allis-Chalmers tractor assembly line looked like? Bet you wish you could have taken a tour of it when the plant was humming with activity and churning out the beautiful Persian Orange tractors they were known for. Let’s take a tour back in time..


We will begin our tour with a brief introduction and layout of the Allis-Chalmers Tractor Division

Tractor Shops at the West Allis Works

 The Allis-Chalmers Tractor Shops are located in the heart of one of the greatest industrial areas in the United States. Two thousand one hundred (2,100) men and women work on 20 acres of floor space to provide farm power for today’s living and to develop ideas for tomorrow’s modern and reliable tractors. Here at West Allis we produce the D-10, D-12, D-15, D-17 and D-19 wheel tractors the H-3 crawler tractor, and a variety of power units. These tractors are used in virtually all parts of the world from the wheatlands of Kansas to the northern latitudes of Finland.

The requirements of specialized farming machinery and an increased demand for utility tractors has created a challenge to farm equipment manufacturers. Allis-Chalmers has met this challenge by producing its farm and industrial tractors on modern assembly lines with such a wide range of options that during 5 years production no one tractor would be duplicated.

We have adopted the material management concept in order to coordinate our Purchasing, Ordering, Scheduling, Receiving, Materials Handling, and Shipping Departments.

The heart of the Materials Department is an IBM 305 RAMAC Computer, shown below, which is used to maintain the records of the 2,300 to 2,500 parts that make up the average tractor. The current status of any one of these parts is available in less than 2 seconds.

The D-17 and D-19 transmission housing are cast in our foundry and machined in the tractor shops on a series of single purpose machines.

Milling D-19 transmission housing

The milling machine, shown the picture, mills the five outer housing surfaces. There are 134 drilled holes and 114 tapped holes in each transmission–four machines accomplish the entire job. The last operation involves boring 12 holes in four sides of the housing at one time.

Assembling D-19 transmission

Transmissions are assembled only after a thorough washing and visual inspection. Most transmission parts are made by Allis-Chalmers–all parts are subjected to rigid quality control during both manufacture and assembly.

Inspecting transmission on test stand

Every transmission is connected to the testing machine and run in each gear, which is another quality control step to assure unfailing performance.

Hydraulic Pump Machine Assembly and Inspection

A high performance piston pump in the D-15, D-17 and D-19 tractors supplies dependable hydraulic power under widely varying temperatures. Seemingly insurmountable problems were solved in the manufacturing of this pump before it was accepted for use in our tractors. There are 96 operations necessary to prepare the pump body for assembly. The position bore tolerances are held to .0002″ (2 ten-thousands of an inch) and are checked by air gauges as shown in the photograph.

General Purpose Machines

The double spindle turret lathe is one of several general purpose machines used for producing a multitude of tractor parts–power steering supports, transmission and torque tube retainers, brake drums and PTO bearing cases and retainers. This versatile lathe can machine two different parts at one time with a high degree of accuracy.

Double Spindle Turret Lathe

Other general purpose machines include drill presses, single spindle lathes, and milling machines. A group of 21 automatic screw machines are used to produce a wide variety of parts consisting of gear blanks, hubs, shafts, valves, plungers, screws, bushings, spacers, plugs, bolts, pins, etc. The bar stock used ranges in size from 7/8″ to 5″in diameter. The screw machines can drill, tap, face, bore, turn, thread, ream, burnish and chamfer bar stock in one setup to produce parts with tolerance–.0005″

The tracer lathes are used mainly for machining several types of shafts. The exact movements of the single cutting tool are controlled by a stylist tracing over a template whose profile is the desired shaft profile. Tolerances are held between .001″ and .005″.

The newest addition to our production facilities is an automatic tape controlled jig mill which, because of its physical location, cannot be included in the tour. The machine movements are automatically controlled by a paper tape which is punched in accordance with dimensions required on the drawing. the bore size, depth and the distance between holes on either the PTO or the final drive housings are machined with tolerances held to .0005″.

Gear Manufacture & Inspection

Allis-Chalmers Tractor Division takes pride in being able to manufacture the finest gears available for use in its product. A total of 47 machines are used to rough and finish cut, shave, hone and lap a wide variety of precision gears. Tolerances are held within .0003″ on the gear tooth profile to assure a perfect mesh.

Cutting Spiral Bevel Gear

The quality of our gears is constantly checked. Our gear lab technicians use the finest gear measuring machines available. The involute measuring machine can magnify the gear tooth profile 800 times to detect any minute variations. Machines for checking base pitch, tooth spacing, and accuracy of helical (spiral) lead are also used.

Honing Gear to assure accurate profile

Checking and recording gear tooth profile

Crankshaft Machining

The crankshaft is a vital engine part. consequently we machine our own from the rough forgings to the finished shafts. Fourteen operation which include turnings, grinding, drilling, tapping and polishing are necessary to completely machine the shaft. The crankshaft journals are polished–almost mirror smooth–down to an 8 micro-inch finish. The crankshafts are subjected to rigid inspection after they have been completely machined.

D-19 Assembly

Assembling torque housing to transmission housing

The personalized quality that went into the machining of parts and sub-assemblies is carried on in the final assembly of the tractor. Inspectors are stationed along the assembly line to assure that the assembly operations conform to our high standards. An overhead conveyor system delivers a continuous flow of sub-assemblies from their place of manufacture to the tractor assembly line.

Attaching engine to torque housing

After the main portion of the tractor is assembled, it is moved through a two-stage high pressure wash and rinse area. Then to the spray paint booths where the famous Persian Orange paint is applied. The enamel is baked on the tractor as it moves through the oven where the temperature is held between 180-200 degrees.

Final assembly prior to washing and painting

The tires, battery, grill, hood, lights, muffler, seat and decals are attached as the tractor moves out of the bake ovens. A calcium chloride solution is mixed at a central location and is piped to assembly lines where various size tires can be filled with a specified amount, ranging from 2.5 to 74 gallons.

D-19 Tractor at the end of the assembly line

The finished tractor is driven to the test and inspection area, where it is given a simulated road test. All gears and the brakes are tested as the rear wheels rotate on free wheeling rollers. The best possible performance is achieved by thoroughly inspecting each tractor and making final adjustments to assure unmatched reliability.

Tractor runs on rollers during final inspection

The quality and reliability of any tractor is highly dependent upon the workmanship that goes into its manufacture. We at Allis-Chalmers pride ourselves on the “Personalized Quality” each tractor receives. We are constantly striving to improve the quality and reliability of each tractor. We feel that each satisfied customer is another salesmen for Allis-Chalmers.

Revitalizing Markesan

Markesan,Wisconsin is quaint little town in central Green Lake County. This past year I had the pleasure of working with the Markesan Historical Society to put a book together, Images of America:Markesan, to depict the history of our town through pictures. The reader can travel back in time to see what Markesan looked like in its younger years and what made it prosper.

While conducting my research and putting my book together, two things became apparent to me. The first was there were a plethora of businesses and jobs in the area. Canning factories, hemp mills, movie theater, jewelers, restaurants, car dealerships, and even a cigar factory! Our town had about anything you could think of. The second was that where are all of these things now? Obviously times change and things close or move out, but why hasn’t Markesan moved with the times?! We lack industry, we are lacking retail and the city is not doing anything to bring people in. These are major barriers that are not allowing our town to thrive like it once did.

Here is an overall map and shaded areas that I would like to address as possible solutions to Markesan’s troubles.

The areas shaded are as follows:

Dark Blue– Hein Park

Light Blue– Bridge Street Business District

Yellow– Industrial Park


The first area of concern, which is correlated with Hein Park in the dark blue, is how Markesan can utilize space to create events to draw in visitors. What does Markesan have that brings in people? Well, we do have some celebrations that bring in large crowds. June Dairy Days is for sure an important event that gets some area attention and some people making their way into town for the tractor pulls, street dances and the parade, but that is 3 days out of the year! There are a couple other celebrations throughout the year, but June Dairy Days is an important one because it does celebrate of community’s strong history in agriculture. What else can we, as a community, do to bring people in and get them into our great city. Surrounding communities have some great things going for them. Princeton has a flea market every Saturday from April to October.Green Lake has a farmers market and Ripon has various things planned all throughout the year too. Why can’t Markesan tap into these kinds of ideas to get people moving through town? Why couldn’t we have a farmers market during the summer to sell produce, or fall harvest fairs to sell pumpkins, gourds and other products? A park would also be a good place to host summer night dances. The possibilities are endless really! It just takes some planning. I found another page that gave some tips for organizing events and step by step process. Check by clicking HERE. It’s about making something that sets Markesan out from other places and attracting people in.


Downtown Markesan 1940s

The next area of inquiry is our downtown business district on Bridge Street. When you look through my book at Markesan’s downtown, it is long gone from its glory days. A few buildings are vacant and no businesses occupy them. Another shame is that siding and other cheap looking building materials have been cobbled onto the buildings taking away from their late 19th & early 20th century charm. This is the gem of our city, and it is looking a little tired. A few of those buildings are pictured in my book are from 1897! The nearby city of Ripon, Wisconsin is undergoing a revitalization of their downtown. Building codes have been put in place to bring back the nostalgic look from yesteryear and to make the town look more historic and appealing. These are the goals of that revitalization:


  1. Market and promote downtown Ripon as a clean, safe and friendly destination.
  2. Position Ripon Main Street, Inc. to provide leadership for collaborative efforts to significantly improve the quality of life and eliminate blighted property.
  3. Provide a positive, productive and nurturing environment that will attract new business and retain existing business downtown.
  4. Promote physical changes to make downtown a more comfortable and exciting place.

If Ripon can do it, why can’t Markesan? With that being said, it is also important to have businesses in town for people to shop in so that a revitalization project would be worth the time and financial input. I wonder if people knew that Markesan once had a movie theater, ice cream store, a jeweler, meat market, bakery and lots of other places on Bridge Street. How can Markesan get some more specialty stores in our downtown?  I found this link which talks about small towns in Pennsylvania, and how they are able to revitalize business downtown. I think we need to ask ourselves what kind of businesses would strive and attract local and visiting patrons. Art, bridal, unique dining and other specialty stores help attract people. Something unique that can set our city apart from others is key and getting businesses to move in to suit those needs is also important. We have a lot of Amish stores in the area! Has anyone ever thought of encouraging the amish communuty to open up an Amish bakery downtown, or a woodworkers shop or something?!


Industry is an important factor in any city, big or small. This is where people work and make their living. This is also what brings people to our city to live. We have a couple in town that helps sustain the community. The Markesan School District is a big employer in town. When a referendum vote was held a few years back the argument was that the city’s survival was dependent on the schools survival. If you look on the map I provided above you will see the yellow shaded area as our industrial park. Once you zoom in on it you will notice something else….it is virtually empty. An automotive shop, medical clinic and snowmobile club garage occupy lots in our industrial park. Where is the industry at?! What are we offering industry as an incentive to set up shop in Markesan? I am not talking big dirty factories either. We are in the 21st century with new high-tech industry and manufacturing. We need to bring them in if we can. We have the farming heritage going for us, but is there a way we can base more industry off of that? The canning factory is a start, but a lot of the workers are migrant and don’t stick around year round.

Final Thoughts

While going through my book, readers will see that it was hard work and toil that built Markesan from the ground up. It took tough decisions and sometimes chances to improve and build Markesan. The people who accomplished it with hard work and determination. Sadly, that evidence of hard work is slowly fading away as time goes on. Markesan is nothing like it used to be. Markesan is standing still watching everyone else propel into the future. City leaders, citizens and business owners need to come together and need to make a plan of action. Younger people are not moving in and the ones that are already here are moving out because the town has nothing to offer for them in terms of jobs or a future. Markesan is not attracting industry that brings jobs which then brings people to make business possible. It might hit a nerve to say this, but some people in the community just flat-out hate change and refuse to take action. Well, sooner or later standing still is going to cause more harm to the community than progression would and the younger generation will be left to pick up the pieces. My biggest hope is that my book will fuel the flames for change in Markesan, so people will want to change the direction of our city. The time is now or never to put aside petty excuses for change saying “we don’t need change, things are fine” or “things will never change”. Change starts with a positive and can do attitude for the future. It’s time for Markesan to live up to its words on the chamber of commerce website that says “Markesan, a great place to visit and even a better place to live!” Get involved in the community, make suggestions and make change!

Oshkosh Brewing Company

Oshkosh Brewing Company

The Oshkosh Brewing Company was a brewery formally headquartered in my college town of Oshkosh, Wisconsin. It was only until recently that I learned of this brewery and began to uncover some of the company’s history. Sadly, the old brewery fell victim to the wrecking ball in 1986 destroying the physical evidence of the company’s existence. Only one of the smaller brick buildings remains on the old Oshkosh Brewing Company grounds on Doty Street in Oshkosh. A big shed now sits were the original brick structure once stood.

The Oshkosh Brewing Company was formally started in 1894 when three breweries in Oshkosh merged together. The breweries involved in the merger were; Brooklyn Brewery, Union Brewery. and the Gambrinus Brewery. The merger was the result of tough economic times that came out of a financial depression a year earlier. Another push factor was competition moving in from Milwaukee. Pabst Brewing Company and Joseph Schlitz Brewing Company were both moving their products up to the beer drinkers in Oshkosh. Carloads of beer from Milwaukee breweries made their way to beer halls in Oshkosh and the local brewers were struggling to compete. The proprietors of those breweries met in the courthouse in Oshkosh in the spring of 1894 to officially merge their breweries together and form one strong brewing entity.

The men who merged their beer brewing company’s together wanted to keep the merger under the radar. On the official document that made the merger legal, the phrase “do not print” was written at the top to prevent the newspapers from leaking the information out. Their attempts to secretly create a new brewery could not be kept secret and soon everyone knew of the Oshkosh Brewing Company. Why did these men want to keep this hidden? Did it hurt their pride that they couldn’t make it on their own and had to join forces with local competition, or was it to have the element of surprise on their beer competitors in Milwaukee? Who knows, but they seemed bashful of recognizing the company they had formed.

Slowly the proprietors of the new firm began to embrace their identity as the Oshkosh Brewing Company and began to build and expand their products and operations. The new brewing company utilized equipment and operated out the former individual breweries that came together to from the Oshkosh Brewing Company. At the turn of the century, the Oshkosh Brewing Company was putting out 50,000 barrels of beer annually. To increase production, a new brewery was commissioned in May 1911  and was slated for opening in May 1912. It was built on the site of the Brooklyn Brewery on the corner of West 16th Avenue and Doty Street.

Around 1900 the company adopted the logo of Chief Oshkosh of the Menominee indian tribe, for which the city of Oshkosh was named after. A giant emblem stood on the front of the building for many years and was saved from the wrecking ball in 1986. It is now on display outside at the Oshkosh Public Museum.

The Oshkosh Brewing Company continued brewing and distributing many different beers, including Chief Oshkosh Beer, until 1971. In October of that year, beer production ceased at the brewery and within a few weeks the Oshkosh Brewing Company was sold to another Oshkosh brewery, Peoples Brewing Company. The Peoples Brewing Company met the same fate and was closed a few years later. Times were tough on the local breweries and it was hard to compete and keep up with the big breweries down in Milwaukee. Nearly 77 years after its creation, the Oshkosh Brewing Company was shut down never to reopen. In 1986 the buildings of the former brewing complex were demolished to make space for new developement in the Oshkosh area.

Chief Oshkosh Beer

There were many breweries in the Oshkosh area in the 19th century. As time went on a few of the bigger and stronger ones remained. Alas, these local breweries met the same fate of the former ones. Trying to compete with the national breweries was a venture the local Oshkosh breweries had a rough time coping with. It is still amazing that my college town had itself a couple of notable breweries that stuck it out against Schlitz, Miller and Pabst down in Milwaukee. I would like to see an exhibit at the Oshkosh Public Museum to remember breweries of Oshkosh’s past. Maybe it can be a project I can work on with them in the future.

My First Book

Earlier this year my first book was published. I can honestly say that if I had to do it all over again, I would not change a thing. This has been one of the most challenging projects I have attempted to date, and I look forward to doing another book like this again in the near future.


The book is part of the Images of America series published by Arcadia Publishing out of Mt. Pleasant, South Carolina. I had originally contacted the publishing company via their Facebook page October 2010. I had read many of their other books in the series and I had emailed to ask if there was any interest of inquiry about doing a book about Markesan. I heard back from someone at the publishing firm within a week of posting that question on their Facebook page. This is what they had to say.

Hi Austin,

I am the Wisconsin acquisitions editor at Arcadia Publishing. You left a comment on our Facebook page about us publishing a pictorial history about Markesan. I have looked into it, and while the market is relatively small—we usually cannot publish books on towns smaller than 5,000 or 6,000—it does look to be an active community with a wealth of history and a local museum. It very well may be doable. We have had success with similar titles.

I took a couple of days to think about this project, because I knew it was nothing like I have ever attempted. I replied and told them that I would be very interested in doing the book. I explained that I was only 19 years-old at that time and that I was a history student at a university. They expressed optimism in working with me and that is not uncommon for young people to work on these books.

The next step, as with any book idea, was to write out a proposal form for the book. It was quite detailed too! It was a lengthy process, but necessary for the publisher to gauge the area and the basic history and information I could give them. It was in the proposal where I was able to give a brief history of our community and it was my first chance to give possible chapter titles.

After the proposal was sent in I was given the official green light on the project, but the paperwork was not done yet. There was the usual legal and contractual paperwork to fill out and finalize before I could do anything. It was around the same time ( November-December 2010) that I was in touch with the Markesan Historical Society asking if they would be interested in co-sponsoring this project. The idea of writing a book about Markesan was warmly welcomed by the society board members.

January 2011 was when I leisurely started working on the book. The contact person from the publisher gave me my first deadline, which was the cover. I was able to submit 2 photographs that I thought would be suitable for the cover and the publisher would put it together to show what the final cover might look like. I was also asked to write the information on the back cover, which consisted of a brief history of the town and the author information. The picture at the top of my posting is what the final book cover looks like. Here is what the cover could have looked liked.

Cover 2

I choose the first image because the landmark downtown area is so common and so well know in Markesan. I think I made the right choice! So I knew early on what cover my book would have, which was exciting.

I worked 2 weeks in January, as I was on winter break at the time, but once February rolled around it was time to head back to school and I was on hiatus from the project until the end of May that year. Once school ended in May I really dug in and began to work on the project. I had a deadline set for November 1, 2011 and I knew I had to complete the majority of it before I returned to school in the fall.

I wanted to break the project up into separate stages. The first stage was setting in stone how I wanted to the book to be organized. The second step was to find and scan the pictures I wanted for each chapter. The last step was going back through all my images and research the images to put the historical information that was pertinent to that image.

The scanning part was as simple as going through the historical society’s boxes of pictures and picture display boards and scanning the pictures to the publisher’s specifications. The hard part came when it was time to identify and write for the pictures. Some pictures had little to no information about them. I spent countless hours researching and cross-examining pictures to pull out the significance. Some useful tools while I did my research were obituaries; some dating back to the 1860’s, Markesan Herald newspapers dating back to the turn of the century, scrapbooks, yearbooks, articles and other countless & priceless documents housed at our wonderful historical society.

Once I had all the information gathered and written for each picture, it was time to submit all the information to the publisher. Before submitting the information all the pictures and captions were gone over for grammatical errors and historical accuracy. I had two other people help me with checking the material. When it was all gone over, I sent the information in September 2011. The editor checked the material and sent it back to me on two occasions. Some last-minute editing and last check for historical accuracy was all done by the end of 2011. By January 2012, everything was ready to go and my book was shipped to the printers.

February 20, 2012 was the big day! My first book was officially released and I became a published author. My blog may make it sound like a cake walk, but it was a challenge that pushed me to new limits and prepared me for my field of history. I recommend anyone who loves history to contact the publishing company and see if they would publish a book about your area too. I have been to 4 books signings and have given 3 presentations about my work in writing the book. The people at home appreciate the effort and the work I put into the project and it is safe to say that more books are in the works for me.

#3 Terre Haute Works

Terre Haute

The Terre Haute Works in Terre Haute, Indiana was constructed to build the compressor components for jet engines. Curtis-Wright had contracted the firm to build the components for their J-65 turbojet engines. Allis-Chalmers announced on April 28, 1951 that they would erect a $25,000,000 facility in Terra Haute. In August 1951 construction got underway to build the brand new Allis-Chalmers facility.

On December 1, 1952 the construction was completed, and the new facility was up and running. Due to some serious labor issues that riddle the construction projects, some of the military tools that were being set up for the production of jet engine components were taken out and never returned. The factory was expected to employ nearly 4,000 people, but that number only reach  700 some personnel. Military contracts for jet engine parts were cancelled and given to other firms.

In mid-1954 a $4,000,000 addition got underway to build an end on complex to create room for the production of switchgears, power transformers, circuit breakers and other non military products. Construction was completed around 1958. Allis-Chalmers was optimistic of its investment in the new facility, thinking that production would improve and the Terre Haute plant would be profitable.

Construction of new addition at Terre Haute Works

Allis-Chalmers boasted that the Terre Haute Works housed the most modern equipment available for building and testing their transformers and circuit breakers. On top of that, they claimed that this new factory was keeping ahead “electric utility industry’s ever growing equipment requirements.”*

On February 9, 1962, Allis-Chalmers headquarters in Milwaukee announced that the Terre Haute Works would be shut down later that year. Management claimed that cost and price problems were to blame. Manufacturing that was taking place at the plant would be moved to both the Pittsburg Works & the West Allis Works and employees could be transferred to different plants upon request.

#2 Boston Works

The second Allis-Chalmers complex to be examined is the Boston Works in Boston, Massachusetts. This was one of the many other factories part of the Allis-Chalmers firm.

In 1931, Allis-Chalmers Mfg. Co. acquired the American Brown Boveri Electric Corporation and the Condit Electric Mfg. Co., together both specialized in turbines, steam engines, generators, switch gears and transformers. Allis-Chalmers chose the Condit Electric Mfg. Co. factory as the Boston Works branch of the Allis-Chalmers firm, where electric circuit breakers were produced.

Condit Electrical Manufacturing Company
Boston, MA

Condit Electric Mfg. Co. was a subsidiary of the American Brown Boveri Company. The latter was a branch the of the Swiss based company, Brown Boveri. The firm expanded in the United States in October 1925 in Camden, New Jersey. The company prospered during World War I by building ships and machines that were installed on the ships. They wanted to shift production to turbines, generators. transformers, and other electrical equipment. The Condit Electric Mfg. Co. of Boston was acquired for their production of electrical switch gears. The Condit Electric Mfg. Co. was known for oil circuit breakers, on both indoor and outdoor sizes. Other firms across the U.S. were also bought out to add more lines of equipment to the company.

The company was hit hard during the Great Depression and tariffs (tax) on imported goods were too high to be able to import material from Switzerland, so the firm decided to sell off its lines to cut losses. The electrical division was sold to the Allis-Chalmers Mfg. Co. in 1931.

With the addition of this branch, Allis-Chalmers had acquired a line of mercury arc power rectifiers, generator voltage regulators, transformers, and heavy-duty electrical railway locomotive motor and control equipment. After the acquisitions, Allis-Chalmers became the only licensed firm in the U.S. to manufacture and sell turbo-blowers and turbo-compressors  designed by the Brown Boveri Company. By 1939 Allis-Chalmers became the third largest electrical manufacturer in the United States behind General Electric and Westinghouse.*

Allis-Chalmers Electric Equipment Ad

Allis-Chalmers had the largest toroidal winding and taping machines, which built transformer components, housed at their Boston Works. The plant also built large circuit breakers for switch gears that were installed and operated other automated factories. Allis-Chalmers claimed that their electrical equipment could “handle any size of power interrupting job.”*

Due to inefficiency and rising costs, Allis-Chalmers was forced to shut down and relocate some operations. I believe this was the fate of the Boston Works. I ran across some information that suggests that operations were moved from Boston to Jackson, Mississippi in 1973. I found a report from the Boston Historical Society that suggests that in 1974 the Boston Works was damaged by a fire ( the report said the building was vacant in 1974.) When I do find something I will be sure to update this post.
