Description: |
| Abstract:
This invention relates to tool-holders for use in lathes for turning bolts, screws, pins, &c., and the toolholder is particularly adapted for use in turret-machines. One of the objects of our invention is to positively move the tool-carrier toward and from the work in such a manner that the cut will always be on the center line of the work, so that the tendency to break the tool due to catching or digging into the work is entirely obviated. Means are provided for adjusting the throw of the tool-carrier according to the depth of cut and the diameter of the work.
Claim:
In a device of the class described, a tool-carrier movable toward and from the work, a o guide upon which the tool-carrier slides, a "cam rotatably mounted on one of said members and in operative engagement with a seat in the other, to positively move the tool-carrier on its guide, an actuator rigidly secured to and to rotate the cam, and means mounted on the tool-carrier and cooperating with the actuator to vary the movement of the tool-carrier toward the work. |
