J. 3. BACK. 5 TOOL PUST.

JOHN R. BACK, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO THE F. E. REED COMPANY, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
TOOL-PO ST.
SPECIFICATION forming part of Letters Patent No. 709,693, dated September 23, 1 902.
Application filed October 13. 1897. Serial No. 655,011. (No model.)
T on whom it may concern:
Be it known that I, JOHN R. BACK, a citizen of the United States, residing at Worcester, in the county of WVorcester and State of Massachusetts, have invented a new and useful Improvement in Tool-Posts, of which the followingis a specification, reference being made to the accompanying drawings, forming a part of the same, in which- Figure 1 represents a front elevation of a tool-post embodying my invention. Fig. 2 is a side elevation of the same, and Fig. 3 is a vertical sectional view on line 3 3, Fig. 1.
Similar letters refer to similar parts in the different figures.
Referring to the drawings, A denotes a toolrest provided with a plane upper surface A and a .T-shaped slot B to receive the head C of a bolt C. Resting upon the upper plane surface A of the tool-rest is a post D, having a hole through which the bolt C extends.
The post D is clamped upon the surface A by means of the bolt C and a nut C and is capable of adjustment along the tool-rest by loosening the not C and sliding the bolt in the T-shaped slot B and of further adjustment by rotating the tool-post around the bolt.
At the upper end of the post is an overhang- 3o ing lug E, which carries a pair of bindingscrews F F, adapted to be screwed down upon a cutting-tool G. The cutting-tool G rests upon a block H, having its lower surface concave and curved in the arc of a circle and fitting the convex surface of the block I, which rests upon the surface A of the tool-rest. The toolrest shown in the drawings consists of the ordinary sliding tool-rest commonly used in lathes, and the T-shaped slot B is arranged, preferably, transversely thereto or parallel with the body of the lathe and allows the tool-post to be shifted on the upper surface of the tool-rest in the line of the slot B.
The blocks H and I are movable and are adjusted on the tool-rest to suit the position of the cutting-tool A. When the block II is placed directly over the block I, the upper surface of the block II and the lower surface of the block I are parallel and support the tool in a position parallel with the upper face A of the tool-rest, but by moving the block H endwise upon the block I its upper surface can be inclined, permitting the cutting-tool to be tilted and its cutting edge raised or lowered.
I am aware that tool-holding devices have been employed in which the post was provided with an overhanging lug carrying a binding-screw by which the tool was clamped in position, and I do not claim such broadly.
The post D is provided at its base and on the side opposite the overhanging lug E with a projecting flange J, which rests upon the upper surface A of the tool-rest, so as to increase the bearing-surface of the tool-post upon the tool-rest upon the side opposite the overhanging lug E in order to resist the strain upon the tool-post caused by clamping the tool G by the screws F E. The head C of the bolt C is elongated in the direction ofthe T-shaped slot, so that the strain exerted by the clamping-screws I F and tending to tip the post laterally will be received by the walls of the T-shaped slot.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is
1. The combination of a tool-rest having a plane upper surface and provided with a T-shaped slot, a post resting upon said toolrest and having on one sideaprojecting flange resting upon the tool-rest and on its opposite side a lug overhanging said tool-rest, said flange and lug being disposed in the same direction as said tool, a clamping-screw held in said lug, whereby a tool resting upon the tool-rest is held in position, a bolt extending vertically through said post and having an elongated head also in the direction of the T-slot and inclosed in said slot, substantially as described.
2. The combination of a tool-rest having a plane upper surface and provided with a T- shaped slot, a post resting upon said tool-rest and having on one sideaprojecting flangerestsupport the tool and permit the same to be ing upon the tool-rest and upon the opposite tilted, substantially as described. side alug overhanging the t001-rest,a clamp- Dated this 6th day of October, 1897.
