It is one object of my invention to provide an improved self-contained belt drive for a machine tool, the belt preferably running on a single pulley on the machine spindle.
Another object is to provide a construction in which the driving mechanism is mounted in the base or pedestal of the machine in such-manner that the tension of the driving belt may be easily adjusted.
More specifically, my invention comprises change speed mechanism pivotally mounted in the base of the machine and movable as a unit about its pivot to vary the belt tension,
A furtherfeature of my invention consists in so constructing the change speed mechanism that it is removable as a unit from the machine without disturbing or dismantling other parts of the machine. |
