TOOL- HAN DLE.

SPECIFICATION forming part of Letters Patent No. 512,971, dated January 16, 1894.

Application filed September 27,1893. Serial No. 486.599. (No model.)

To all whom it may concern:

Be it known that I, JAMES J oHNsToNE, of the city, county, and State of New York, have invented a new and Improved Tool-Handle, of which the following is a full, clear, and eX- act description.

My invention relates to improvements in tool handles; and the object of my invention 1s to produce a very cheap, simple and stron g tool handle which is especially adapted for holding a brad awl.

In the accompanying drawings Figure 1 is a side elevation of the handle embodying my invention, a tool being held therein. Fig. 2 is a longitudinal section of the handle. Fig. 3 is a detail perspective View of the ferrnle which is secured to one end of the handle. Flg. 4 is a plan view of the removable jaw which is fastened to the ferrule, and Fig. 5 is an inverted plan view of the said jaw.

The handle l0 may be of any usual shape, and at its smaller end it is provided with a ferrule 11 which may be attached to the handle in any convenient way, such as by a screw l2. The ferrule has an internal shoulder 1 3 near its outer end to enable it to rest firmly against the handle so as to resist strain placed endwise upon it, and the'ferrule has a bore which is large enough to permit the tool shank to be conveniently inserted. The ferrule has at its outer or lower end a projecting portion 14, which'serves as a fixed jaw and against which bears one edge of the polygonal liange 15 of the brad awl or similar tool 16. The shank 17 of the tool 16 enters acentral hole 18 in the handle (see Fig. 3,) adapted to receive it, while the i'lange 15 finds an end or thrust bearing against the outer face of the shoulder 13.

The ferrule is provided on one side and near the lower end with a notch 20, having an inclined rear wall, as shown in Fig. 3, and this enables an implement, such as an awl, to be inserted beneath the flange 15 0f the tool, so that the latter may be easily removed, and consequently, if the tool is broken, it may be readily taken out and a new one sub stituted.

The tool is held in place by the fixed jaw 14, above referred to, and by a detachable hollow jaw 22 which has, at its lower end, an

inwardly projecting claw 23 which is grooved on, the edge, as shown at 21, to enable it to fit snugly upon the tool 16 just below the flange 15. The jaw 22 tits over a boss 25 on one side of the ferrule 11, and itbears against the boss which thus serves to take the strain off the fastening screw 26, by which the jaw is clamped to the ferrule, this screw extending through a hole 27 in the back of the jaw 22 and into a threaded hole 28 in the boss 25. It will be seen that by tightening the screw 26 the jaw 22 may be fastened very solidly to the ferrule, and the claw 23, engaging the tool and its ilange 15, holds the tool against endwise displacement and also against turning, as the flange 15 is rectangular or otherwise polygonal, and bears against the jaw 14, so thatthe tool cannot turn. To remove the tool one has merely to free the jaw 22, place an instrument in the notch 20 and beneath the flange 15, and then lift the tool from the handle. Y l

As above remarked, the handle is particularly intended for holding a brad awl, as illustrated, but it will be readily seen that many other small tools may be held conveniently by it.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A 'tool handle having at one end a central opening for the shank of the tool, a tixedjaw projecting beyond the end of the handle to form a bearing for a polygonal [lange on the tool, and a detachable jaw secured to the opposite side of the handle and provided with a grooved claw to fit over the tool beyond its flange, substantially as described.

2. A tool handle having at-one end a central opening for the shank of the tool, a fixed jaw projecting beyond the end of the handle to form a bearing for a polygonal iiange on the tool, and a detachable jaw secured to the opposite side of the handle and provided with a grooved claw to tit over the tool beyond its .lange, and means as a screw for fastening the removable jaw, substantially as described.

3. A tool handle having at one end a central opening for the shank of the tool, a fixed jaw projecting beyond the end of the handle to form a side bearing for the polygonal flange on the tool, a shoulder 13 to form an end or thrust bearing for the said flange, and a detachable jaw having a claw to fit over the {iange of the tool,

4. Atool handle having at one end aferrule with a projecting end jaw, a threaded boss on the side of the ferrule opposite the fixed jaw, a detachable jaw having a claw projecting over the handle end and a screw passing through said detachable jaw into the thread-` ed boss, substantially as and for the purposes described.

5. The improved tool handle having at one end a ferrule with a projecting end .ja-W, a boss on the side of the ferrule opposite the xed jaw, a hollow detachable jaw to fit over .the boss, the detachable jaw having an indescribed.
