JAMES DICKSON VAUGHAN, OF FORDYCE, ARKANSAS.

LOG-HOOK.

SPECIFICATION forming part Of Letters Patent N0. 626,946, dated June 13, 1899.

Application filed August 10, 1898. Serial No. 688,242. (N0 m de -l T0 (0 whom it may concern:

Be it known that I, JAMES DICKSON VAUGHAN, a citizen of the United States, residing at Ford yce, in the county of Dallas and State of Arkansas, have invented certain new and usefullmprovements in Log-Hooks; and I do hereby declare the 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.

In the use of chains for binding logs, lumber, and the like upon wagons and cars it is common to employ ahook upon one end thereof which is adapted to engage one of the links of the chain. As the logs or lumber spread apart in being transported, however, great difficulty has been experienced in disconnecting the hook from the chain owing to the great strain to which the chain and hook are subjected. The usual method of discone necting the hook from the link at such times is by forcing the same through the agency of an ax or other like instrument. This is apt to break the hook or bend it into such form that it is thereafter useless.

Certain inventions have been made to overcome the objections above noted, but all of them with which I am acquainted are difficult to manipulate and ineffective in securing the ends of the chains together.

Myinvention is designed for the production of a hook for the purpose above set forth which may be readily attached to any of the links of the chain, will be held securely in locked position when so attached, and which pivoted between said standards and provided with a nose adapted to engage the rearwardlyextending branch of the hook proper.

In the accompanying drawings,Figure 1 represents a side elevation of my improved hook in looking position. Fig. 2 is a similar view of the same in its unlocked position. Fig. 3 is a longitudinal section. Fig. 4 is a plan View.

Like reference-numerals indicate like parts in the different views.

My improved device is made up of a body 1, having an eye 2 at one end, to which one end of the chain is connected, a pair of angularly-arranged upwardly-extending parallel lugs or extensions 3 3 at the opposite end and a pair of parallel upwardly-extending lugs or standards 4 4 at a point intermediate of its ends. Pivoted to the parallel extensions 3 at a point intermediate of its ends and located between said extensions is the hook proper, 5, consisting of an integral bar having arounded outer edge and a slot 6 therein, forming two branches, one constituting an engaging portion 7 and the other a rearwardly-project- -ing arm 8. The extreme end of said arm 8 is cut away or beveled, as shown at 9, for a purpose which will hereinafter appear. Pivoted to the lugs or standards 4 and located between them is a locking-lever 10, having a rearwardly-extendin g handle 11 and a head 12, provided with an eccentric or cam-shaped nose or olfset 13.

When it is desired to couple one end of the log-chain with the other, the handle 12 of the operating-lever is elevated, one of the links of the chain inserted into the slot 6, and the hook proper, 5, swung rearwardly until the arm 8 thereof passes between the lugs or standards 4, with its lower edge resting upon the upper surface of the body 1. The handle of the operating-lever 10 is then swung downwardly, bringing the nose 13 on the head thereof into engagement with the inclined or beveled face 9 of the arm 8. Any outward strain uponthe hook 5 is resisted by the eccentric nose on the lever 10, which nose is located at a point on said lever opposite the pivotal connection between it and the lugs 4 and opposite the handle 11. It is therefore impossible for the hook to become accidentally disconnected from the link without an upward movement of the operating-lever. When it is desired to uncouple the ends of the chain, it is merely necessary to raise the handle 11 of the lever 10, when the hook 5 will move in the direction of the strain exerted upon it by the chain, enabling the link of the chain to slip freely from the slot 6.

The parallel extensions 3 and standards 4 serve not only as means for pivoting the hook proper and operating-lever to the body, but also serve to guide the hook proper in its movement and to prevent lateral displacement thereof when the same is in its locked position.

Having now described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hook comprisingabody, a hook proper pivoted thereto, and a locking-lever having a cam-shaped nose adapted to clamp the hook proper against the body.

2. A hook comprising a body, a hook proper pivoted thereto at a point intermediate of its ends, one of the branches thereof having an inclined or beveled surface, and a lockinglever having an eccentric engaging portion- In testimony whereof I affix my signature 35 in presence of two witnesses.
