Description: |
In the ordinary lathes the belt which runs the counter-shaft requires to be shipped from the tight to the loose-pulley and the motion of the spindle afterward stopped by placing the hand upon the pulley cone. This occupies considerable time and is a matter of considerable inconvenience, especially when the work requires considerable changing. It will be observed that, with my improvements, this inconvenience and delay are obviated therefore it will readily be perceived by those skilled in the use of lathes that my improvements are of great utility and practical value, inasmuch as no time is lost in shipping the belt or stopping the motion of the spindle, while the operation of the clutch and brake being performed with the foot the operator has both hands free, so that he can conveniently attend to any requirements of the work. |
