Belt-Shifting Mechanism
|
Robert W. Kremer |
Cleveland, Cuyahoga County, OH |
Claim:
The present invention, relating, as indicated, to belt shifting mechanism, is more particularly directed to a mechanism for shifting the belt on a drill press or similar machine tool. There are of course a number of different mechanisms in more or less general use for shifting belts on lathes and tools of that character, but there are but few mechanisms which may be used on dri11 presses to advantage, and one of the chief objects of this invention is the provision of a simple and inexpensive mechanism which may be used for the purpose stated on a drill press. |
