Paul Luckman's Hummer gas engine follows conventional layout, with hit-and-miss governing, a spark plug and buzz coil, atmospheric intake valve and a single cast cylinder and water hopper. Photos by Paul Luckman.
I am hoping someone can come up with some information on Hummer engines. My engine is cast in one piece except for the wet head. The bottom of the main casting is open, similar to an Alamo. The engine appears well built. The engine is silver. “Hummer” appears in green stencils on both sides of the hopper. The serial number, 8283, is stamped in the head. It has a 3-7/8-inch bore and a 4-inch stroke. The crankshaft is 1-1/2 inches in diameter. I would guess it to be 1 hp. It has splash oiling for the crank end of the connecting rod with cast grease boxes for the crank lube. I would like to know who built it and when, as well as what its original color was.

Hummer engines are something of a mystery. Hummer Manufacturing Co., Springfield, Illinois, was connected to Montgomery, Ward & Co. In 1916, Montgomery Ward purchased Racine-Sattley, which shortly thereafter was renamed the Hummer Plow Works, the Hummer being a popular plow made by Racine-Sattley. The company changed its name to Hummer Manufacturing Co. about 1931. Available information suggests Hummer didn’t start making engines until the mid-1930s, but those engines appear to have been air-cooled, not water-cooled. Wards marketed a 1-1/2 hp Sattley engine, and apparently sporadically marketed engines under the Hummer name. Yours is not the first to surface, although they appear to be quite rare. If you know more, please contact Paul and GEM.
