The Burroughs Class 3 machine is based on the mechanism designed by William H Pike Jr for the Pike Adding Machine Company. Pike appears to have worked previously for William Burroughs in St Louis, as his name appears as inventor on American Arithmometer patents from 1897. Pike left St Louis around 1901 and established his Pike Adding Machine Company in Orange, New Jersey. Production commenced in 1904, and was well established when the company was acquired by Burroughs in 1909. When Burroughs relocated the manufacturing operation to Detroit, the Pike factory in Orange was acquired by the newly-formed Monroe company.
The Pike machine was smaller, simpler, and cheaper than the Burroughs, but its biggest advantage was the visible printing. The printed results were in full view of the operator, rather than hidden at the back of the machine at te class1 types. Burroughs continued to develop the machine into the 1920s, adding features such as two-color and split printing, wide paper carriages, direct subtraction, and electric motor drive. The machine was sometimes known as the "flat-bed" after the long horizontal arrangement of the keyboard and the display register.

One key top is broken at first cleaning. An top layer of oil or ? which is preventing the lack from shining. When this is after extensive force, it seems to get away, but I stopped removing it op not critical areas. |

| Machine story: | Machine is functional on arrival, the total sum is not clicked in, but when hold down manual, it works. The ink ribbon is obviously dry. After lift the case it was packed in dust. Never seen such an amount. I'm pretty sure that I lift it for the first time, (need special tool to open the front lock). After cleaned it the uncovered metal parts showed hardly rust. De cast iron showed in shiny paint. The case was covered with oil, after heavy cleaning with car paint cleaner it was shiny again. |
