Allis-Chamers Mfg. Co.
A cut from the 1910 Allis-Chalmers engine catalog shows the frame for a 2500 K.W. engine. The company pointed out that the bead at the man’s shoulder was the floor line, thus bringing the valve gear and other parts within easy reach of the operator. Even with bearing liners in the crankshaft housing, space remained for a gigantic crankshaft. Machining these huge castings with accuracy required even large machine tools. By 1915 Allis-Chalmers had begun building their Diesel-
Type Oil Engines. They were offered in one, two,
three, and four-cylinder models, and built in 14×21,
16 x 24, and 18 x 27 inch sizes. These engines were
available into the early 1930s. A great many were sold
to oil and gas pipeline companies.
history
Allis-Chalmers had its beginnings back in 1847 as a manufacturer of stone buhr mills. Allis steam engines appeared in 1884, the same year that the company built America’s largest centrifugal pump. In 1903, Allis-Chalmers began building large gas engines under license from the Augsburg-Nurnberg patents from Germany. In 1932 Allis-Chalmers introduced an entirely new series of smaller lightweight engines, including the Model L-O. In addition
to this oil engine style, there was also a
Model L gasoline engine with a displacement
of 844 cubic inches. It remained in production
until 1950 when it was slightly revamped and
became the L-844 power unit. Over the years,
Allis-Chalmers developed and built a host of
power units for virtually any application.
