A/C storage building??

Recommended Posts

Here at the college, I was walking to class yesterday and I passed by these metal buildings, I couldn't tell if it was an air conditioning unit, or a storage building but it had Allis Chalmers on the sides, as well as Siemens-Allis on the sides too. I can't figure out what it would enclose. Any guesses???

I'd guess some sort of electrical equipment. I found this searching for "siemans-allis": Allis-Chalmers manufactured some of the most durable and effective electrical control equipment used in the United States for over 75 years. Due to their rugged design, much of their equipment is still in service today. As economic difficulties overtook the Allis-Chalmers conglomerate, a partnership was formed with Siemens AG in 1978 creating the company known as Siemens-Allis. In 1985 Siemens AG bought out the remainder of Allis-Chalmers' interest in their partnership and established Siemens Energy and Automation. Since that time, (1985), Siemens has replaced or obsoleted much of the Allis-Chalmers and Siemens-Allis equipment they owned.

Tractors made up a very small fraction of the Allis-Chalmers empire. There is a writer in "Antique Power" magazine who was a district sales rep for AC in the 50s. In each issue, he tells a story about working for them. Once, he told about the district sales office that AC built in Chicago. The company brass didn't have a lot of faith in the tractor division, so they built the building very plain with heavy floors and high ceilings so that it could be converted to a factory for one of the other divisions, in case the tractor division failed. At the nuclear power plant where I work, there are four 4500 horsepower Allis-Chalmers motors that power the pumps that circulate the water through the cooling tower. Each pump is rated for 140,000 gallons per minute.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
