ABSTRACT:
An overload safety device is provided for use on a feed mechanism to control the feed of such devices as a headstock, tool rest, or rotary table. The overload safety device includes a mounting means for maintaining a feed screw in a fixed position with respect to an axis of rotation of the screw and for permitting the screw to move a predetermined distance along the axis in response to a load placed thereon. The safety device further includes control means responsive to the movement of the screw for producing a control signal when the movement of the screw exceeds the predetermined distance, thus indicating an overload condition.
