Application To all whom it may concern:

't known that I, Dnmam) E. Cox, a citithe United States oirlmerica, residaside, in the county of Clatsop and ite of Oregon, have invented new and useful Improvements in Logging-Hooks, of which the followin is a specification.

The object of the invention is to provide 11 w an novel form of hook to be used cularly by lumber men and persons enged in similar work where it is necessary maintain the hook connected with gray le chains or similar devices, despite whether the hoisting machine rope becomes slack or not. To this end the invention comprises body having a hook formed herewith and a keeper for the hook, the -eeper bein engaged by the thumb latch no "nted in the body, but not exposed above the suiiace thereof, so that there is no danger or accidental displacement oi the l which will permit its releasing the The invention is illustrated and described in a specific embodiment to which, however, it is not to be restricted. The writer reserves to make such changes or alterations as the actual reduction to practice may suggest, in so tar as such changes or alterations are compatible in spirit with the annexed claim.

In the accompanying drawings:

Figure 1 is a perspective view of the improved hook.

2 is a longitudinal sectional view.

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 1.

Referring to the drawings, the invention is shown as comprising a body portion 1 formed integral with which there is a hook the latter terminating in a nose 3 of wedge-shape conformation and reduced both thickness and width at the base or the wedge where it connects with the main portion oi"- the hook.

The body portion 1 is formed with an eye l extending transversely through the same and this body provides means for an at tachment of a hoisting machine or rope to the device.

:1 keeper 5 is employed to close the hook and prevent its disconnection from a ma chine to which it may be attached. This keeper is pivotally mounted on the body portion and is provided with a relatively thin disklike shank 6 which lies within a slot Specification of Letters filed February 11, 1919.

formed in the body portion directly beow the hook. A pintle 8 is mounted transsel in the body portion and crosses the .ot l, passing also tnrough the shank 6 at the center of the atter, the engagement between the sl ank and the pintle, however, being loose enough to permit it and the to be swung away from or against the hook. The keeper is formed with a pocket 9 in which the nose 3 engages when the keeper is in the position of closure for the hook and the keeper is further provided with a clearance notch or recess 10 for the said nose when it, the keeper, is swung away from the hook.

To positively maintain the keeper in the position of closure, the body 1 adjacent the ye i is counter-sunk as at 11 and is further termed with a rectangular hole 12 opening on the other side of the body from the coun- "-sunk portion but communicating with re latter. The counter-sinking extends to 1 e slot 7. Therefore the rectangular hole st crosses the said slot. The shank 6 is de of such diameter that its edge proides into one side of the hole 12 and this edge is notched. as at 13, the notch leaving rectangular hole 12 clear when the keeper is closedin position. A rectangular shaped. block 1e: conforming to the hole is formed with a shank 15 and this block rests in the hole and its shank passes through nto the counter-bore 11 in which there is eccived a spring 16 which is compressed net-ween the bottom of the counter-bore and a head or cap 17 attached to the upper end of the shank 15. When the keeper is in the position or closure, the block it may engage in the notch 13 and the keeper will thus be prevented from swinging away from the rook. but wncn the head 17 is depressed the block is forced downward or laterally away T0111 the notch 13 whereon the keeper may be swung backwardly away from the hook to permit the disengagement of the hook from anything to which it may be attached. That end of the block which connects with the shank in the open position of the keeper bears against the side of the disk or shank 6 but when the keeper is swung to closed position this block is permitted to enter the notch 18 and retain the keeper in such closed position. With tie keeper in closed position the head 1? lies fiushwith the adjacent side of the body 1 so that there is no danger of the keeper being released by accidental is'claimed as new contact or impact with some outside object.

\Vhen the keeper is released, the head is de pressed into the counter-bore and the block is forced away from the shank 6 releasing the latter when it is lower, or its free end lies flush with the opposite side of the body 1.

From the foregoing description and the accompanying drawings, it is believed that a clear enough understanding of the invention is to be had to render further description unnecessary.

The invention having been described what and useful, is:

A device of the kind described comprising a body formed with a hook and having a slot, a keeper for thehook having a disk like shank lying in said slot, a pintlemounted in the body and crossing the slot and pivotally engaging the said disk-like shank, the said shankbeing formed with a notch, the body being formed on one side with a rectangularslot and on the other side with a counterbore connecting with said slot, a rectangular-shaped latch element mounted in the rectangular slot and engaging with the notch in the shank when the keeper is in closed position for the hook, and a spring disposed in the counterbore connected with the latch to the latter into engagement the shank.

In testimony ture.
