Last year I got the engine, a 1 HP Gray, from Kim Johnson, a local implement dealer. He had hauled it down from Fairlight, Saskatchewan where it had originally run a cream separator.

The old farmer that had it said they had thrown it out because it never ran right, but the Associated engine they replaced it with was worse.

When I got the engine, it was a real : basket-case. I began restoring it in my Junior High School shop class. It had thrown a rod and there was a chunk out of the block where the oiler sits. The rod cap was missing, along with all of the governor parts (somebody had made a new one and they did a poor job of it), the pushrod, rocker arm, lubricator, and muffler were missing, along with some other small bits and pieces.

The head was a real mess, too. The valve guides were broken off with the valves bent over inside them, the little fork that holds the rocker arm was broken in four places. The threaded boss where the muffler screws in was also broken off. The needle valve in the carburetor was bent over and rusted solid, too.

When I managed to get the piston unstuck, I had another unpleasant surprise. There were no rings, and the end of the connecting rod was nearly rusted away to nothing (I can't imagine why, it had been sitting in a manure pile since 1940).

This little engine must have been a scapegoat for someone's anger and frustration because they even broke the crank in the flywheel and there are dents in the castings where someone had been pounding on the poor thing. 

The compressor I bought from one of my neighbors. He thought it would be the perfect thing to run with an antique gas engine and it turns out he was right. Nobody has ever seen anything like it before.

The compressor was in pretty good shape and it had been stored inside. All I had to do to it was make another pulley for it (the compressor had two), and find some grease cups for it.

The belt switcher is something that my Dad and I devised. It uses an unloading valve and an air cylinder to power a fork that moves the belt. The unloading valve opens and powers the air cylinder when the air pressure in the reservoir tank reaches 60 PSI. When the pressure drops, the valve closes, bleeds off the air cylinder, and a spring moves the fork from the idling to the working position.

I made a belt tightener so it can be clamped at the desired tension, making it easier on the bearings. The tightener doesn't bounce up and down like some do.

The cart, the gauge, the buzz coil, and the small valves and parts came from flea markets, auctions, and our junk box.

I think the engine was made about 1915. I heard that it was made by T &. M Motor Company of Wisconsin for Gray Motor Company.

The air compressor was made by F. W. Spacke Machine Co. of Indianapolis, probably sometime in the late 1800's. I would like to hear from anyone who knows anything about it or the engine.

My parents are restoring a wooden threshing machine. It is made by the Doylestown Agricultural Works of Doylestown, PA. It is a very small machine. It does not have a wind stacker, an elevator, a recycler, or even a sacking attachment for bagging the grain. This machine has an overshot cylinder and a straw rack.

The threshing machine was designed to be pulled by horses, because the grain infeed table folds around to make a seat for the driver. This would mean that the machine was made somewhere around the turn of the century.

They would like to hear from anyone with information on it.
