Description:
Abstract:

In the usual kind of machines employed in the cutting of metal and known as "slotting-machines" the return or ineffective stroke of the cutting-tool occupies or entails an expenditure of as much time as does the outward or effective stroke. Hence considerable time is wasted and expenses thereby incurred. To produce mechanism that will perform the return or ineffective stroke of the cutter at a greatly-increased speed as compared with the other stroke, and by the employment of parts that are of comparatively little cost and yet that will allow the adjustment or regulation of the stroke of the cutter to be readily effected is the object of our invention.

Claim:

In a slotting-machine a ram made to slide upon the framework, a lever for transmitting motion to said ram, a cam-wheel having a cam disk or flange secured to it, said wheel and disk being mounted on said lever, a pinion and disk or flange secured to it mounted on the frame and means for operating said pinion, in combination.
