(ModeL) PIGK. I

, Patented Feb. 6, 1883.




SPECIFICATION formingpart of Letters Patent No. 271,797, dated February 6, 1883.

Application filed May 23. 1882.

(ModeLl To all whom it may concern:

Be it known that I, WARREN 000K, of Allegheny City, in the county of Allegheny and,

The invention consists in a pick construct- Y ed with a platehaving recessed wings and transverse grooves, whereby 'when the plate is folded sockets will beformed for the handle and for the tapered ends of implements-such as mattocks, pick-points, hammers, axes, &0.- which ends of the implements are passed into ,the sockets formed by the folded plate, and are held therein, so that my im'moved pick can be used like an ordinary pick but the diiferentimplements can be changed very easily and. rapidly as the circumstances may require. The folded plateis held together by rivets or bolts, and the folded plate is held on the handle by a ring placed around the ends of the recessed wings. I

Reference is to he had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding partsin all the figures. l

Figure l is a longitudinal elevation of my improved pick, showing two pick-points secured in the sockets. Fig. 2 is an edge elevation of the same. Fig. 3 is a plan view of the plate forming the sockets, the plate being extended or unfolded. Fig. 4 is a perspective view of the hammer. Fig. 5 is a perspective view of the mattock. Fig. 6 is a perspective view of the pick-point. Fig. 7 is a perspective view of the ax. Fig. 8' is an edge elevation showing a modification of the socket.

A metal plate, A, is provided with two opposite lateral wings, B, which are stamped or pressed toform recesses or countersinks U, which are rounded, enlarged, and deepened at the inner ends, so'thatwhen thesewings arev The two wings are held against the handle D by a tapering ring, E, which is passed over thelower ends of the wings when the same are folded against the handle.

The plate A is provided with two transverse grooves, F, with beveled sides ortriangular cross-section, which grooves extend across the plate A, at or near right angles to the wings B, and these grooves are tapered from both ends toward the middle, so that when the plate is folded the grooves F will form two tapering squared sockets, H, for receiving the tapering squared ends of picks, hammers, &c. The sides of the plates are held to each other when folded by bolts or rivets Gr, passed through them, as shown in Figsl and 2. The sockets H will extend longitudinally along the upper part or edge vof the folded plate held on the handle, and the sockets willbe slightly inclined from the middle of the top of the folded plate toward the ends. The pick-point J, the hammer K, the mattock L, and the ax M are provided with squared tapering eudls N, which fit into the sockets H, and at the inner ends of the tapering ends these implements are each provided with a shoulder, a, which restsagainst the outer ends of the sockets H and prevent the implements from being driven too far into the sockets. The folded plate A, forming the sockets, is held firmly on the handle D, and can be attached and detached very rapidly and conveniently, and the implementssuch as a pick, mattock, adz, ax, &c.-can be easily placed into thesocketsH and removed from the same, so that the pick can easily be adjusted forits ditt'erentuses.

If desired, the sockets H can be arranged to have the bottom side at right angles to the upper edge of the plate A, as is shown in Fig.

8, the tapered ends of the implement having a corresponding position in relation to the cut-- at the inner ends, and with transverse grooves.

having beveled sides, and which are tapered from the ends toward the middle, substantially as herein shown and described, and for the purpose set forth.

2. In a pick, the combination,with the handle D, of the plate A, provided with recessed wings B and transverse grooves F, and of the bolts or rivets G, for uniting the plate when folded, substantially as herein shown and described, and for the purpose set forth.

3. In a pick, the combination, with the handle D, of the plate A, provided with recessed wings B and transverse grooves F, the bolts or rivets G, and the collar or ring E, substantially as herein shown and described, and for the purpose set forth.

4. In a pick, the combination, with the handle'D, of the plate A, provided with recessed wings B and transverse grooves F, forming sockets H, and of implements-such as picks, mattooks, hammers, &c.having' one end squared and beveled, and provided with a shoulder, a, at the inner end of the squared and beveled part, substantially as herein shown and described, and for the purpose set forth.
