. DRAFT-HOOK.

Specification of Letters Patent.

' Application filed January 5, 1920. Serial No. 349,493.

To all whom it may concern:

Be it known that I, IRA H. MONTELIUS, a citizen of the United States, residing at Portland, in the county of Multnornah and State of Oregon, have invented a new and useful Improvement in Draft-Hooks, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to draft hooks as a class.

The object of my invention is to provide a device wherein an automatically acting lock prevents the release of the link of a chain engaged by the hook, and at the same time the lock is easily operated to release the link when desired. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Figure 1 is a front elevation of the device with a chain link therein.

Fig. 2 is a side elevation of the same.

Fig. 3 is a front elevation showing position of lock and link when about to be disen aged.

ike characters refer to like parts in the views.

A clevis 4: is provided, having transverse openings in the free ends thereof. A pin 5 extends through the said openings, the pin having a head 6 on one end and an opening 7 in its opposing end in which a cotter pin 8 is placed. The hook is retained in pivotal position on the pin 5 by means of its head and the cotter. A hook 9, having a bill 10, of common type, is provided. The hook is pivotally mounted near the upper end of its shank on the pin 5, between the forks of the clevis 4. The head of the hook has flat surfaces on each face. Between the hook 9 and the opposing fork of the clevis 4 a forked lock 11 is pivotally mounted in its upper end on the pin 5. The forks of the lock 11 extend downwardly a desired distance between the shank and bill of the hook, the flat outer surface of the lock being in parallel, vertical alinement with the bill and a sufficient distance from the bill to clear it. Integral angle'd wings 12-12 extend rearwardly from the lock 11, in a manner whereby the same are opposed to the respective sides of the shank of the hook 9 and each will engage the shank as the lock 11, swinging on its pivot, brings a wing into contact with the shank. An end link 13, of a chain Patented July 20,1920.

or cable, is shown in positions related tothe hook and look. I

It will now be seen that when it is desiredto remove the end link of a chain or cable from the hook, the lock 11 is moved to one side as shown inFig. 3. The link is then tilted to one side and'slid upwardly along the bill andwithin the forks 'of the lock. When the link passes over the bill, the lock is swung in the opposite direction and the link easily slipped from the forks of the lock alongside of and free from the bill. T 0. place the link on the hook, the lock is movec to one side and the link passed upwardly into the forks of the lock. The lock is then swung in the opposite direction to allow the link, in tilted position, to be slipped over the bill and downward into engagement with the hook as shown in Figs. 1 and 2 It will be seen further that the lock swings between the shank and bill of the hook, and its path of travel is limited therein b y the engagement of the wings'12-12" with the shank of the hook. The space between the shank and bill of the hook is thus closed to such an extent that the engaged link cannot be released from the hook in any other manner than by operating the lock and the link in relation to the hook as described. It is practically impossible for the parts to automatically adjust themselves to such releasing position. For all practical purposes the device therefore efficiently locks the chain link upon the hook and it cannot be disengaged therefrom during, a draft operation. The

operation of the device is extremely easy,

and its construction very simple and economical. It is novel and useful for logging or any other business in which a hook undergoes much jerking and impacts with other objects.

I claim- I 1 1. In a device of the character described, the combination of, a hook of common type having a flat surfaced head, and a member having a flat surfaced head pivoted in sliding engagementwith the fiat head' of the hook, also having forked parts extending downwardly between the hook shank and bill a desired distance, said forked parts being provided with angled wings extending outwardly alongside the opposing surfaces of the hook shank,in position toengage the opposing surfaces of the shank as the member swings to and fro on its pivot, for the purposes indicated.

2. In a device of the character described,

mon type, having a flat surfaced head,

pivoted in the clevis, and a member clevis in sliding engagement -with the fiat head of the hook, also having forked parts extending downwardly between the hook shank and bill a desired distance, said forked parts being provided with 10 angled Wings extending outwardly alonglng a flat surfaced head pivoted in the.

side the opposing surfaces of the hook s ank, in persi ie t9 engage the pp surfaces of the shank as the member swings to and fro on its pivot, for the purposes indioated.
