Application filed December 11, 1885. Serial No. 185,398. (No model.)

To all whom it may concern-:

Be it known that I, Algernon Gilliam, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have 5 invented a new and useful Improvement in Tool-Handles, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, makingpart of this specification.

io My invention relates to improvements in tool-handles; and it consists in providing a handle-socket and a handle so adapted that the handle may be secured in the socket by an internal wedge.

My invention further relates to and consists in adapting the free end or shank of the socket for engagement with a variety of tools; also, further relates to and consists of a termination of the socket-shank into a serrated disk, and arms or braces having- on one of their ends disks serrated and adapted for engagement with the disks on the socket, their free ends adapted for engagement with various tools; also, in bifurcating the socket-shank and adapting the free ends of the prongs for engagement with various forms of tools.

My invention also relates to and consists of the detail and combination of parts as described, and set forth in the claims.

Similar letters of reference indicate corresponding parts in all of the drawings hereto attached.

Figure 2 is an isometrical view of my invention, showing the handle in the socket, a part 35 of which is cut away, reducing the figure in that division to a sectional view, showing the end of the handle and wedge in position in the socket. This drawing (Fig. 2) will be referred to and used in illustrating the herein follow40 ing specification so far as relates to the annular conical socket B.

A represents a wooden handle turned in a conical form, as shown in Fig. 4. B is an annular conical socket, and may be made of mal45 leable iron or any other suitable metal, and of such dimensions as to adapt it to the required use. The annular bore of the socket B tapers from the point of entrance at a to a point, δ, preferably including- about two-thirds of the 50 entire length of the annular bore, purposely contracting the bore to less diameter on a line from δ to δ than from a to a. From the point indicated by a dotted line extending from δ to δ the inside wall of the bore diverges, enlarging- the bore, so that its diameter at a point 55 indicated by the dotted line from c to c will be larger than the diameter from δ to δ. From the point c to the bottom end of the wall the lines of the bore may be parallel, or they may diverge or converge. I would prefer to have 60 them slightly converging·.

The free or handle end of the handle A (see Fig. 4) may be of any of the well-known and approved forms and adapted for various uses. The other or tool end is conical, the taper 65 adapted to the converging lines of the bore of the socket B, between the letters a and δ, and to continue to taper at the same rate of reduction in size to the end of the handle. The shank of the socket B is bifurcated, and the 70 free end of the prongs adapted for engagement with various forms of blades. In this case the ends of the prongs are provided with two lips, (a short lip, e, and a long lip, /,) the long lip /having a perforation, <7, for a screw or rivet. 75 A blade may be passed between the lips e and / and secured by a screw or rivet placed in the perforation g.

The manner of applying the socket B to the handle A is as follows: Start the wedge C into 80 the end of the handle A at h, place the wedge and handle into the socket B, the outer or butt end of the wedge resting against the bottom of the socket. By driving or otherwise forcing the handle into the socket, the wedge will 85 penetrate the end of the handle and spread it out against the wall of the socket, so as to firmly secure the end of the handle in the socket, requiring no further means of fastening the handle into the socket. 90

Fig. 1 is an isometrical view of socket B, as hereinbefore described, which terminates in a single shank, D, having quadrilateral perforation/ adapted to secure a great variety of tools. Fig. 3 is an isometrical view of socket 95 B, as hereinbefore described, terminating in a single shank which is provided with a disk, k, having serrations I on each side or face, and a central perforation for a clamping-bolt, m.

E E are arms or braces having on one of ico their ends disks n, adapted to the serrations on the disk k. The free ends are provided g

338,264 with fingers o andp, to adapt them for engagement with a variety of tools, that may be set at different angles with the handle.

I am aware that it is old to secure a tool to 5 a handle, by means of disks secured, respectively, to the handle and tool and having serrated faces, and a bolt passing through the disks for locking the disks together, and hence I make no broad claim to such a construction,
