TOOL HANDLE.

Application filed March 12, 1921.

To all whom it may concern:

Be it known that I, CHARLES A. humans, a citizen of the United States, residing near Marion, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Tool Handles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the handles of such tools as chisels, and the like, and the object of the invention is to provide a handle for such tools, well adapted for serv ice, but easily and quickly detachable, so that the tools may be stowed in a shorter space, and so that one handle may serve for a number of tools.

The invention is fully desclosed in the description and claims following, reference being had to the accompanying drawing, in which z- Fig. 1 is a face view of a joiners chisel provided with my improved handle. Fig. 2 is an edge view of the same, the handle parts being in section. Fig. 3 is a view of the connecting nut as seen at the smaller end. Fig. l is a section of the same and connecting parts in a plane transverse to that of Fig. 2.

In the drawing, the numeral 5 denotes a chisel bit of the form commonly known as firmer, having a round, conical shank 6. Instead of being hollow to receive a handle, however, the shank terminates in a screwthreaded stud 7. This fits anut 8, which in practice is made somewhat more than double the length of the stud, and is threaded throughout its length. The nut is also internally grooved at 9 to receive a sliding key-plate 10, which may be briefly designated as the key. This key connects by a suitable notch therein with the T-head 11 of a bolt 12 screwing into the opposite end of the nut, and forming the core and striking portion of the handle, which should fit nicely thereon so as to be screwed in position by grasping and turning said handle. The handle itself, that is to say, its external part 13, may be of hard wood, hard rubber, laminated sole-leather, or other suitable material.

As shown in Figs. 2 and 4:, the key serves to hold the tool-bit from turning with respect to the handle when in normal posi tion, the stud 7 being notched at 7 to re- Specifieation of Letters Patent.

ceive the edge of the key. This notching of the stud, or, more exactly, the length of this end of the nut, should be such that when the stud is locked by the key the abutting end of the nut and the adjacent shoulder of the shank fit neatly and snugly together. A stop-screw 1 L engages the end of the key when partially retracted, and serves to keep the handle, nut and key always connected.

The handle is connected with the chisel shank by screwing the nut on the shank stud until seated, the key being retracted. The handle now being turned forwardly the key is carried into the notch in the stud, and the handle seated on the connecting nut. To detach the handle it is only necessary to turn the handle backwardly until the nut comes off the shank-stud.

Having thus described my invention, I claim 1. Combined with a tool-bit having a threaded stud, notched to form a key-seat, an engaging nut, a key slidable but non revoluble therein, to engage said key-seat, and a handle having a stud threaded to engage the other end of the nut, and adapted to thrust the key into its seat.

2. Combined with a tool-bit having a threaded stud, an engaging nut internally grooved endwise, a key slidable in said grooves, and a handle having a similarly threaded stud, with a. terminal T-head to engage a corresponding notch in the key, the tool bit stud being notched to receive the edge of the key.

3. A tool shank having a threaded stud notched to engage a key, a stud-engaging nut grooved to receive the key slidably, a key mounted therein, and a handle having a central bolt threaded to engage the other end of the nut, andwith a terminal T-head to engage the key.

4:. Combined with a tool-shank having a notched and threaded stud, a longitudinally grooved nut, a key to engage said notch mounted in the nut, a stop to prevent its displacement, and a handle having a threaded stud revolubly but insepara-b y connected with the key while screwed into connection with the other end of said nut.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES, A. WALTERS.
