Abstract:
In the embodiment chosen for illustration the operating tool is a milling cutter carried by a reciprocatable head sliding in a vertical guide- way, and the means for advancing and retracting the tool slide includes a lever arranged to be grasped and moved in the appropriate direction by the operator's hand. While the action thus effected is literally a manual one, I wish to make is not necessarily limited to the performance of this operation by the hand rather than the foot or some other part of the operator's person; in other words the term "manual" as used in this specification is to be construed as including the muscular actuation by the operator, however applied. The objects of the invention are to improve and simplify the means for driving the tool spindle of such a machine and means for counterbalancing the weight of the vertically movable tool-carrying slide. These objects are accomplished by providing an electric motor as the prime mover, with accessories later described, and by causing the motor itself to serve as the counterbalance for the tool slide. Secondary objects and characteristics appear in the following specification. The invention comprises all novel characteristics, combinations and principles of the specific machine.
Claim:
In a machine tool, a spindle carrier, guides engaging said carrier and constraining it to move in a straight line, a lever having arms at opposite sides of its fulcrum connected by one of its arms to said carrier, a driving motor mounted on the other arm of said lever as a counterweight to said carrier, and a driving connection between said motor and spindle. |
