GRIM, a citireduced laterally, the inner side of the inner zen of the United States, residing at East Radend being beveled or inclined outwardly, as ford, in the county of Montgomery and State indicated at 5, so as to fit snugly within a 55 5 of Virginia, have invented a new and useful corresponding socket or recess 6, formed at Pick, of which the following is a specification. the inner side of the eye portion of the oppo- This invention relates to picks, and is parsite member 2.

The inner end portion of the member 2 is With these and other objects in view the provided in its outer side with a transverse present invention consists in the combination notch 11, which forms an inner terminal hook and arrangement of parts, as will be herein- 12, having an outer transversely-rounded aftermore fullydescribed,shown in the accomside. A segmental lug or projection 13 is 75 25 panying drawings, and particularly pointed formed upon the outer rounded side of the out in the appended claims, it being underhook and is located substantially midway bestood that changes in the form, proportion, tween the opposite ends of thehook.

Figs. 2 and 3 are deing groove or recess 15, formed in the inner 85 3 5 tail perspective views of the opposite removwall of the socket 13 and continued into the able points or members of the pick-head. socket 9, so as to facilitate the entrance of the Fig. 4 is a central longitudinal sectional view lug into the groove. The latter interlocking taken through the pick-head and transversely parts prevent longitudinal play of the memof the handle.

From the foregoing description it will be Like characters of reference designate corunderstood that the opposite pick sections 0r responding parts in all of the figures of the members are assembled. by first applying the drawings. member 2 to the member 1 in an inclined po- 95 45 Referring tothe drawings,1 and 2 designate, sition, as indicated by dotted lines in Fig. 4 respectively, the opposite points or members of the drawings, so as to engage the hooks 12 of the present pick-head, which have their inand 111, after which the members are closed or ner ends overlapped and recessed upon their swung inwardly in opposite directions upon overlapped inner sides, so as to jointly form the connection formed by the interengaged roo 5o the eye 3 for the reception of the usual hanhooks asacenter,whereby theluglS is entered dle d. Each member or section tapers to a into the groove orrecess 15 and thebeveledinpassage of the fastening, and its outer end isl countersunk, so that the head of the fastening may lie Within or flush with the adjacent outer side of the pick-head, whereby the latter is free from projections.
It will be understood that the handle is in-l serted into the eye before the fastening 16 is applied, and by tightening the latter the members are tightly gripped upon the handle. To remove the handle, it is merely necessary to loosen the fastening 16, and by reason of the smooth opening 18 the members may be slightly separated upon their hinged connection, thereby releasing the handle. Also the handle may be replaced by a reverse'adjustment of the parts. By this arrangement a single handle may be applied to several different kinds of pick-heads formed for different kinds of work, and the handle may be conveniently removed when it is desired to sharpen or repair the pick.
It will be observed that the joints of the pick members lie at opposite sides of the handle or the eye for the reception of the handle, one of the joints permitting of the members being swung laterallyin opposite directions and in the same plane, while the opposite joint has a detachable or adjustable fastening, whereby the handle may be conveniently removed and replaced without entirely separating the pick members.
Upon examination of Fig. 5 it will be seen that the middle of. the eye portion of each member is bulged or convexed transversely, asindicated at 18, whereby the greatest thickness of the eye portion is at the middle there` of, and the opposite sides of the head end of the handle are also, concaved longitudinally to correspond to the bulge of the pick members, and thereby secure a snug and rigid fit therefor. The pick-handle is somewhat reduced in thickness by having its opposite sides concaved and flares outwardly in opposite directions from the middles of the concaved portions, thereby forming an enlarged head portion at the extremity of the handle to prevent Y outward displacement of the pickhead and van annular shoulder at the inner side of the pick-head to prevent displacement of the latter inwardly along the handle.
l. An implement of the character described, comprising opposite cutting members, which have their inner end portions overlapped and provided with corresponding transverse recesses forming a handle-receiving eye, the outer ends of the respective members being end of the said other member and the adjacent portion of the one member.
3. An implement of the character described, comprising opposite cutting members having their inner ends overlapped and provided with corresponding inner recesses forming a handle-receiving eye, the inner end of one member and the adjacent portion of the other member having interengaged hooks forming a separable connection at oneside of the eye, and a detachable fastening at the opposite side of the eye.

4L. An implement of the character described, comprising opposite cutting members, having their inner end portions reduced and overlapped, and also provided with corresponding inner recesses forming a handle-receiving eye, the outer side of the inner end of one member having a transverse socket forming an inner terminal hook, and the shoulder formed at the inner end of the reduced portion of the other member having a corresponding recess forming a hook, the two hooks being interengaged and forming a separable connection for the members, and a detachable fastening for the members at the opposite side of the eye.-
5. An implement of the character described, comprising opposite cutting members, having their inner ends overlapped and provided with inner corresponding recesses forming a handle-receiving eye, the inner end of one of the members having a hook, provided with an intermediate lug or projection upon its outer side, and the adjacent portion of the other member having a recess for the reception of the hook, said recess having a groove or notch in its wall for the reception of the lug or projection, and a detachable fastening for the members at the opposite side of the eye.
6. An implement of the character described, comprisinga handle, having a terminally-enlarged head, and a shoulder located inwardly from the same, and acutting-head formed in overlapped detachably-connected sections,
the overlapped portions of which embraceh the handle between the terminally-enlarged head portion and the shoulder thereof.
