SPECIFICATION forming part of Letters Patent No. 400,803, dated April 2, 1889. Appltli filed September 3, 1888. Serial No. 284,406. (No model.)

To` aZZ whom t may concern:

Be it known that I, HIRAM C. STOUFFER, a citizen of the United States, residing at Mineral Ridge, in the county of Trumbull and State of Ohio, have invented new and useful Improvements in Picks, of which t-he following is a specification.

My invention is directed to improvements in picks more particularly adapted for use in mining, and in which the pick-head is secured for ready removal and replacement by a new one when worn out; andthe objects of my improvements are to provide a firm fastening for the handle-socket, to afford facilities for the adjustment of the socket-fastening device, to compensate for the shrinkage and looseness of the handle and maintain the firm connection of the latter with the socket, and to provide a firm connection of the pick-head with the handle-socket. I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure l is an elevation of the prick. Fig. 2 is a sectional View. Fig. 3 is a view in perspective of the handle-socket, showing the means whereby the socket-fastening device may be adjusted to maintain .the firm connection of the socket With the handle.

The metallic socket part a receives into its socket the enlarged end of the handle, and is riveted thereto at b. As this riveting is not sufficient to maintain the firm connection of the socket part with the handle, I construct the socket part to receive one or more supplemental fastening devices, which I will presently describe. The outer solid end of the socket part is recessed at c, vso as to leave flat bearing parts d CZ at each end, from the face of which pins e e proj ect. The socket has a central screw-threaded opening, f, in its outer solid end, and between it and the end projections, d d, it is formed with openings g g, which extend through the solid end into the socket proper, so that the handle is driven into the socket over the inner ends of these openings. Through these openings metal wedges h h(one or more) are driven into the end of the handle at its junction with the solid end of the socket, so as to spread and bind the end of the handle firmly within the socket. As the handle shrinks, or from other cause the socket part should become loose, these wedges may be tightened by driving them farther through the openings into the handle by removing the pick-head.

In this way the handle can be kept firmly bound within the socket, and the riveting is reenforced, so as to tighten the wood around it.

The pick-head sets solid and flat upon the flat end bearings, d d, of the socket part, and 6o it is formed with holes t' t' in its inner side to receive the pins e e, which project from said end bearings. This gives a firm bearing of the pick-head upon the fiat ends only of the socket part, so that when the pick-head is secured by a screw, Z, passing through a central opening, m, in said head and into. the screwthreaded hole f in the solid end of the socket the pick-head will' be firmly secured, so that it may be readily removed and replaced, or 7o a new picl -head secured upon the socket when desired. The central opening in the pick-head is recessed at the outer side to receive the head of the bolt.

The pick-head is secured upon the socket part over the openings and the wedges therein, whereby should the Wedges become loose they are retained in place, and can be tightened by driving them farther into the handle through openings in the socket. the wedges are made adjustable, and their ends are always exposed in the openings, so that they may be driven farther into the handle when required. For this purpose the openings are permits the wedges to be driven so as to be free of the pick-head and give ample room for their adjustment. By having the recess in the socket end the pick-head will have no In this way 8o about an inch in depth, which bearing upon the latter, except at its flat 9o and should the handle be- IOO I claim as my improvementl. A socket part for pick-handles, having its solid outer end provided with openings g g on each side of a central screw-threaded hole, j, in combination with the handle, and 011e or more wedges, h, driven into the latter through said openings, substantially as described.

2. A socket part for pick-handles, having its solid outer end provided with openings g g on each side of a central screw-threaded hole, f, and having flat end bearing parts, CZ CZ, each having a projecting pin, e, in combination with the handle, one or more wedges, 7L, driven into the latter through said openings, the picl-liead having the holes 'z' t', and the fastening screw-bolt therefor, substantially as described.

The combination, in a pick, of a metallic socket part for receiving the handle, having a central screw-threaded opening and openings On each side thereof, in combination with one or more wedges driven into the handle through said openings, the pick-head,

and the screw-bolt for securing the head upon the socket part over the said openings and their wedges, substantially as described.

4. The pick-socket part having its Outer end recessed at c and provided with a solid part between said recess and the socket, having a central screw-threaded opening, f, and an opening, g, on each side Of said central Opening, the said openings terminating in the socket and in the recess, combined with the handle secured over the inner ends of said openings, the Wedges 7L, driven through said openings g into the handle, the pickhead secured in the sockctrecess over the butt-ends of said wedges, and the fasteningscrew, as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
