SPECIFICATION forming part of Letters Patent No. 645,565, dated March 20, 1906. pplleationiiled April 7, 1899. Serial No. 712,196. (No model.)
To all whom, t may concern.: Be it known that I, EPHRAIM MANEs, a citi- Zen of the United States, and a' resident of Chattanooga,l in the county of Hamilton and State of Tennessee, have invented a'. new and useful Improvement in Tool-Handles; and I do declare the following to be a full, clear, and exact description of the same, such as Will enable those skilled in the art to make and use my invention.
The object of the invention is to provide an improved tool holder or handle which is simple in construction and effective in operation,
the same being provided With a reversible clamping member having a handle portion which may be turned rearwardly in line with the handle member of the holder or turned to extend forwardly in line with the tool to be gripped by the hand of the operator or to serve as a rest for the thumb.
For a more detailed description of my improved handle referencel .is to be had to the accompanying drawings, forming a part of this specification, in which similar characters designate the same parts throughout the several views.
Figure lis an elevation of my improved handle shown attached to the file. Fig. 2 is a longitudinal section of the same. Fig. 3 is a crosssection taken on the line 3 Sof Fig. 2. Fig.4 is a perspective view of my improved cam-lever.
A represents the handle, which is generally made of cast metal, cored out, though any other suitable material may be used. It will be noticed that this handle is the usual shape on the exterior except for the slot @,Which may be of any suitable shape, though the one shown is preferable. This slot passeslongitudinally through a part of the handle and through the enlarged part a to form a rest for the pivot at a2. In the modication shown the swelled portion extends around the entire circumference to make the handle symmetrical, and this is the preferred form, though modifications are obvious and immaterial.
a8 designates the hole through which the tang of the le or other tool passes, and a4 is the lug onwhich the end of the tang rests. This lug is preferably hollowed out on top to more firmly and easily receive and seat the 5o tang. g i rlhe handle is made as light and thin in the walls as possible to make it vlight and more convenient. for,use. .Ifind that it is unnecessary to make the walls more than one-eighth of an inch in thickness except' in the places indicated in the drawings.
B is the cam-lever, which vconsists of the' handle b and the` camsurface h', which is curved eccentric to the pivots b2. The lever is 66 hollowed out at b3 to allow the insertion of a pointed instrument to raise the said lever. It is obvious that the handle and lever are made independent, separate, and distinct and are finished before they are iitted together.
C is an ordinary file, with the usual tang c. In Fig. 2 the tang is shown curved, but this feature is immaterial.
When the handle is to be used, the tang of the file or other tool is inserted when the le- 7o ver is in aposition perpendicular to the axis of the handle. When sufficiently far in, usually when in about the position shown, with the tang resting on the lug a4, the lever is lowered to the position shown in Fig. 2, and the cam-surface clamps the tang and securely holds the tool between the opening a3 and the lug a4. By this means a secure fastening is assured. The tool can be removed by nsert= ing an instrument at b3and prying up thelever 8o with the edged as a fulcrum. After this has been done the tool can be readily withdrawn.
It will be observed that the cam is a double one, as shown at b4 and b in Fig. 1l.
The lever can bethrown forward as well as backward, and thus form a rest for the thumb, as desired.
Having thus described my invention, what I desire to secure by Letters Patent is covered by the following claims: l 9o 1. In a tool-holder, the combinatiomwith handle member adapted to receive'the tool of a clamping member pivoted to said handle and having a handle portion adapted to pro ject beyond the handle member and over the tool to constitute a finger-rest, substantially as described.
2. In a tool-holder, the combination with a handle member adapted to receive the tool, forwardly beyond the handle member over and a reversible clamping member pivoted to said tool to form a finger-rest, substantially said handle member, and having a handle as described. portion, said clamping member adapted to 5 clamp the tool with its handle portion extend- Vitnesses:
