CANT-HOOK.

SPECIFICATION forming part of Letters Patent No. 374,877, dated December 13, 1887.

Application filed May 3,1887.

.To a/ZZ whom it may concern:

Be it known that I, CHRISTIAN N YGAARD, a citizen of the United States, residing at the city of Oshkosh, in the county of vWinnebago and State yof Visconsin, haveinvented certain new and useful Improvements in Cant-Hooks; and I do declare Vthe 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, reference being had to the accompanying drawings," and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements on socket and clip (or clasp) of a canthook.

The objects of my improvements are- First, to construct the clip separate from the socket, so that if the clip is broken the socket is not destroyed, and if the socket becomes broken or worn out the clip can be used.

Second, to strengthen the clip and to lessen the cost of manufacture of .clip and socket. The clip, being separate, can be made of better and strongermetal than the socket, and the labor and expense of casting in separate pieces is less than casting and making clip and socket in one piece.

Third, to construct the socket movable upon the clip, so that if the wooden handleV shrinks the socket may be moved upthe handle without altering position of the clip.

Fourth, to have the clip bolted through the socket and handle.

Fifth, to provide a V-shaped or forked stop at lower end of socket to prevent it from slipping on frozen or icy logs.

Sixth, to provide a back-stop to prevent the hook from striking the hands of the person using the cant-hook.

I attain these objects by the construction illustrated in the accompanying drawings, in which- Figures 1 and 7 are side views of the canthook; Fig. 2, a top view of part of the canthook; Fig. 3, a crosssection; Fig. 4, a side View of clip; Fig. 5, a bottom view of clip, the bolt being shown in section, the plane of section passing through the bolt on line x x, Fig. 4; Fig. 6, a side view of V- shaped stop and Serial No. 237,292. (No model.)

portion of the socket, the latter being shown in section. Fig. Sis an end view of the socket, showing the stop in elevation.

Similar letters refer to similar parts throughout the several views.

A is the iron socket fitted upon the wooden handle D.

E C, Figs. 1, 4, and 5, is the clip, made of iron and fastened through the socket and handle by the nut J, Fig. 1. C is the clip-bolt, upon the lower end of which the nut .I is screwed. E is the clip-head.

I make the clip in one piece, of wrought iron, steel, or malleable iron; also, in two pieces, the bolt of wrought-iron or steel set into the head of malleable iron. The -clip bolt is round, except near the head, where it is of oblong shape at H, with a pointed projection on each side, I I, Figs. 4 and 5. These' projections fit closely into and correspond with opposite notches in the top opening of the socket G. The hole in the handle is shaped to receive the oblong enlargement H on the bolt-head. From the spindle of the bolt a web of metal, L L, Figs. 4 and 5, extends to the enlargement H, with which it cooperates in preventing the bolt from turning as long as it rests in its seat, Fig. 2. This opening is from one to two inches longer than the oblong part of the bolt H, allowing the bolt to fit into said opening. The notches in the opening are one-fourth to one-half inch wide, and are cfa number depending upon the difference between length of socket-opening and oblong part of bolt. Three notches at each side are sufficient. There is also an oblong vopening or slotl1ole,7 similar to H in shape, in the bottoni of the socket to allow the socket to slide on the bolt there. 4

When cant-hooks are made, the socket is put on to allow for shrinkage of the handle. After the wooden handle shrinks, then by loosening the nut .I and raising the clip out of the notches the socket may be forced farther up the handle, either one or two notches, and the clip again fastened without altering its position on the handle. Thus when the clip is first set the part H would be against the edge of the opening G at t', Fig. 2, with the projections I I in the rst notches. After moving IOC) -socket-slot.

the'socket the part II would occupy the position of the dotted lines in the. opening G, Fig. 2, with the projections I I in the middle notch, Ste. The clip-bolt is strengthened by being enlarged at H and provided with lateral proj ections to t into notches in the sides of the The oblong shape prevents the bolt from turning sidewise. The socket eX- tends above the clip on the handle and prevents weakening where the clip-bolt passes through. The back-stop E is part of the clip, and prevents the hook F from coming back so far as to strike the' hands of the person using the cant-hook.

B, Fig. 2, is a top View, Fig. (i a side View, and Fig. 8 an end elevation, of the V- shaped stop. It is a part of the socket, about onehalf inch high, and sharpened to an edge on top.

As shown in the drawings, the tines of the forked stop extend upwardly along the socket and incline away from the same, and the ends of said tines are undercut at their upper ends. By providing the V-stop with a sharp edge it cuts into a log more readily, and more firmly engages the same. Vhen a log is coated with ice or slimy matter this is of especial service.

j By undercutting the limbs of the V the points hook into the log and prevent backward slipping of the lever, the log being firmly wedged between the clip and the stop.

The improvement in having it V-shaped is that when a person is using the cant-hook and power is applied the V is embedded in the log and acts as awedge to prevent or stop the end of the cant-hook from slipping upon the log. rIhe more power applied the more the Wedge or V becomes embedded in the log and stops from slipping.

Therefore, what I claim as my invention, and desire to secure by Letters Patent, is-

l. In a cant-hook, the combination ol the handle, the clip, the bolt securing the clip to the handle, and a socket slotted where it surrounds the bolt to permit adjustment of the socket on the handle. l

2. In a cant-hook, the combination of the handle, the clip, the bolt securing the clip to the handle, said clip being pivoted to the bolt, the bolt-head being provided with an enlargement, and a slotted socket, the walls of the slot being recessed to receive the enlargement, for the purpose set forth.

3. In a cant-hook, the combination of the handle, the bolt secured thereto, the bolt-head having lateral projections, the socket slotted around the bolt, the sides of the slot being notched to engage the lateral projections, and a clip pivoted to the bolt-head.

4. A socket for a cant-hook having a forked stop upon its lower end, the tines ot' the fork pointing upwardly and away from the socket and being undercut at their upper ends,where by the stop may firmly engage a log and prevent backward slipping of the lever.

5. A socket for a cant-hook having a V- shaped stop upon its lower end, the limbs of the V inclining upwardly and away from the socket, being integral with the socket and tapering to a point at their engaging ends, whereby the stop may rmly engage a log and prevent backward slipping of the lever.

6. A socket for a cant-hook provided with a stop upon its lower end, the stop inclining at an angle to the longitudinal axis of the socket and sharpened to an edge on its engaging face, whereby forward slipping of the lever is prevented.

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

CHRISTIAN. NYGAARD.
