Guide-pulley
|
John H. Flynn |
Cincinnati, OH |
"This invention relates to means for supporting pulleys used as guide-pulleys to guide belts where the transmission of power by them from one shaft to another is at an angle and where the belt operates in conjunction with the so-called 'speed-cones.' These latter consist of a number of pulleys side by side, but of different diameters, so that as the belt is shifted from one to the other a variable speed may be had..."
The inventor was the proprietor of a small used-machinery dealer, Economy Machinery Co. This drill press seems to be the only product they ever manufactured, and that occurred only 1898 to 1900 and then it disappeared from their ads. |
