Many years ago, I visited the Coolspring, Pa., engine show and, while it was virtually all old engines, there were two tractors in attendance. One was a 1917 Bullock Creeping Grip crawler and the other was a 6hp Quincy tractor from 1914, neither of which I’d seen before. I was able to find out a little about the Bullock Creeping Grip, but not much has turned up on the Quincy.

Car builder shifts gears

In the fall of 1910, William Colby, a Mason City, Iowa, man who had started several successful companies including the People’s State Bank of Mason City, decided to get into the car business. Colby hired David W. Henry, who had been fooling around with cars for 10 years, to design and oversee the manufacture of the new Colby automobile.

Three 40 hp, 4-cylinder Colby autos were quickly built in time for the Chicago Automobile Show in February 1911, and in the summer of 1911 a Colby race car driven by Indy veteran Billy Pearce placed third in the Kane County Trophy race in Elgin, Ill. Pearce won several big races in his No. 20 Colby “Red Devil” machine until dying in a crash late in the year. Colby introduced a new “underslung” car for 1912, but it was rather expensive and the Colby company finances were a shambles. In December 1911, Colby merged with National Co-operative Farm Machinery Co., Davenport, Iowa.

Meanwhile, John F. Appleby had invented a cotton picker and was looking for a company to market the machine. Appleby is famous for perfecting the knotter mechanism that made twine tie binders possible and is still in use on today’s square balers.
