HANDLE-FASTEN ER.

SPECIFICATION forming part of Letters Patent-No. 746,086, dated December 8, 1903.

- Application filed April 18, 1903.

To all whom, it may concern;

Be it known that we, RICHARD S. HOYT, HENRY P. HOYT, and ERNEST C. HOYT, citizens of the United States, residing at Fortside elevation of our appliance detached.

cam-face 13.

Fig. 5 is a top plan view of the appliance. Fig. 6 is a sectional view on the line 6 6, Fig. 5, looking in the direction of the arrows.

7 represents an ax, shown for purpose of illustration, and 8 is a handle of any approved style therefor, both being broken away, the

handle bein'g in the usual opening through the ax provided for that purpose.

9 is a recess formed in the ax and com munieating with the handle-opening referred to,the

rear wall of which is parallel with the buttend of the ax, while the top wall, as well as the bottom wall, of the recess is formed on an oblique angle, as more clearly shown in Fig.- -3.

10 is an opening formed in the ax and leading upward from the bottom thereof into the recess 9 and provided with suitable screwthreads to be hereinafter referred to.

11 is acrescent-shaped plate having a curvature on its under. side like that of a toolhandle, as best seen in Fig 9. This plate is equal in length to the height of the tool for which it is adapted and is of a suitable material.

12 is a lug integral with and extending from the base-plate 11 and is provided witha Said lug. isv provided near its upper end with' a cam-slot 14, extending in a direction transverse of the base-plate l1.

15 is a screw passing through the'ax and through the cam-slot 14, whereby the plate 11 and its lug are held against displacement and at the same time guided in their movement.

Serial lilo. 153,250. (No model.)

adapted to enter the opening 19, the threads thereof intermeshing with the thread of the said opening.

17 is a rectangular screw 16. This screw 16 is provided with a conical point 18, the cone being on the same angle as that of theicam-face'13 of the lug 12, with which it coacts, as will be fully herein- ,after pointed out.

The parts being assembled in the position shown in Fig. 3, a wrench or other suit-able tool is applied. to the'screw 16, whereupon it is revolved and working upon the threads of the opening 10 it is advanced. In advancing of the. lug 12, whereupon by its continued advancement the plate 11 is crowded toward and against the handle of the tool, thus wedging or locking the handle in the tool or ax 9 facilitates the movement of the lug 12 and plate 11, as does also the cam-slot 14 and the face of the lugin proper relative position with the conical point 18 of the-screw 16, as will be understood by all mechanics.

Any desired pressure may be applied by the continued turning of the screw 16.

Should the handle become loose by reason only necessary to give the set-screw 16 several'turns to again tightly clamp the handle in .ax or other tool.

The top ofthe lug 12 is beveled to adapt it to slide readily on'the top wall of the recess.

It will be thus seen that we have provided a cheap, simple, but e'ifective clamp for the purpose set forth.

What we claim,.and desire to secure by Letters Patent, is-

1. The combination with a tool-head, of a locking-plate placed in the'eye thereof, so that one edge may engage thehandle and the other edge presenting an incline, a screw passing through the head and engagingthe said incline and thereby forcing the plate laterally against said handle.

2. The combination with a tool-head, of a locking-plate placed in the eye thereof, so that 16 is a combined set and locking serew head integral with the its conical point 18 engages the cam-face 13' 7 head.v The angle of the top wall of the recess screw 15, by guiding it and keeping the camof shrinkage or for any other reason, it is one edge mayengage the handle and the other names to this specification in resence of two to edge presenting an incline, a screw passing witnesses.

through the head and engaging the said ineline and thereby forcing the plate laterally 5 against said handle, a pin engaging a transverse slot in the plate to retain it in the head while permitting sneh lateral movement of RICHARD S. HOYT.
