LIFORNIA, ASSIGNOR TO THE WVIET- Specification of Letters Patent.

Patented Oct. 1'7, 1905.

A plication filed February 28, 1905. Serial No. 247,799.

To all whom it may concern:

Be it known that I, EUGENE lVIn'r, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of Cali- Hook, of which the following is a specification.

This invention relates particularly to improvements 1n haine-hooks, but is not limited The principal object is to provide a novel and simple hook in which a link or other connector is securely locked against accidental detachment, the structure of said hook being such that it can be formed of sheet metal stamped or punched by ordinary mechanism, thus making it very inexpensive to manufacture, and, while constituting an efficient lock, being readily operable to release the link or other device held thereby.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the improved hook. Fig. 2 is a cross-sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a detail perspective view of the hook-body. Fig. i is a similar view of the locking device, and Fig. 5 is a detail sectional view on the line 5 5 of Fig. 3.

Similar reference-n umerals designate corresponding parts in all the figures of the drawings.

ln-the embodiment illustrated a hook-body 6 is employed, which is formed of a sheet-metal blank or plate having a front and rear end, the rear end being turned to form an eye 8. A. slot extends into the plate from one of its side edges, preferably the upper edge, and thence longitudinally of said plate toward the front end 7 thereof, forming a shank 7, an overhanging bill 9, an article-receiving seat 10, and an entrance-mouth 11, the free terminal of the bill being furthermore provided with an inwardly or downwardly extending nib 12. The end wall of the seat 10 is preferably thickened by upsetting the metal, as shown at 13, in order to provide an extended wearing-surface.

Pivoted upon one side of the shank in rear of the entrance-mouth 11,, by means of a suitable rivet 14, is a locking device that is preferably, though not necessarily, in the form of a disk 15. The reason for preferring the device to be in the shape of a disk is that it may be readily made by a circular punch. The rivet 14 passes through the locking device eccentrically thereof, but substantially midway between its side edges, and is located in rear of the entrance-mouth 11, as fully shown in Fig. 1. Therefore the disk will under ordinary conditions assume a position across said mouth, consequently closing the same and the article-receiving seat, said disk swinging to this position when moving rearwardly' toward the rear end of the plate. In order to limitthis rearward movement of the locking device and prevent the uncovering of the entrance-mouth 11, a stop-stud 16 may be employed, if desired, which stud, as shown in Fig. 5, may be struck from the metal of the shank and is located in rear of and in the path of movement of the lower rear edge of the locking device, which edge strikes the stud upon the rearward edgewise movement of the disk while said disk is across the entrance-mouth. This is also fully illustrated in Fig. 1.

In order that the locking device may be readily operated by a teamster or other person, it is provided with a projection 17, struck outwardly from the same, and thereby forming a recess or socket 18 in the inner side. This recess is arranged. to detachably receive a projection 19, formed upon the adjacent face of the shank, as shown in Figs. 2 and 3. The projection fitting in the socket when the looking device is in operative position across the mouth holds said device against play and against accidental movement to an inoperative position, yet when pressure is applied to said device by an operator the locking device will pass over the projection 19 on the shank and can thus be swung around to open the mouth and permit therelease of a link, as 20, or other article held in the hook.

From the above it will be clear that the complete hook, including the locking device, may be readily constructed of sheet metal by mechanism well known in the arts, that the same can be inexpensively manufactured, and, while constituting an efficient lock-hook, can be readily operated.

From the fo'reging it is thought that the construction, operation, and many advantages of the herein-described invention will be clear to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, What Iclaim as new, and desire to secure by Letters Patent, is

1. In a lockhook,a body stamped from sheet metal and comprising a plate having a front and rear end, a slot extending in from its upper edge and toward the front end, forming an upper overhanging bill, an article-receiving seat and an entrance-mouth, a locking device stamped from sheet metal and pivoted substantially midway between its front and rear edges and contiguous to its upper end upon one side of the body in rear of the entrance-mouth and directly adjacent to the upper edge of the body, said device having an edgewise-swinging movement toward the rear 7 end of the plate and across the mouth to close the same, and means stamped from the sheet metal of said body and located in rear of the locking device and in the path of movement of its lower rear edge for stopping the device when said device is across the mouth and preventing its rearward movement to uncover the mouth.

2. In a lockhook,a body stamped from sheet metal and comprising a plate havinga front and rear end and a slot extending in from one edge toward the front end of the plate, forming an article-receiving seat and an entrancemouth, a locking-disk stamped from sheet metal and eccentrically pivoted at one side of its center upon one side of the plate in rear of the entrance-mouth, the larger portion of said disk on one side of the pivot having an edgewise-swinging movement toward the rear end of the plate and across the mouth to close said mouth, and a stop carried by the body and disposed in rear of and in the path of movement of said larger portion of the disk to prevent the edgewise movement of said disk rear- Wardly away from the entrance-mouth.

3. In a lock-hook,a body stamped from sheet metal and com prising a plate, said plate having a slot extending in from one edge toward one end of the plate, forming an article-receiving seat and an entrance-mouth, a locking-disk stamped from sheet metal and pivoted at one side of its center between the entrance-mouth and the eye. the larger portion of said disk on one side of the pivot swinging across the mouth to close the same, an outstanding integral lug stamped from the body and located in the path of movement of one edge of the disk to prohibit the edgewise movement of said disk in one direction away from the mouth, and projections struck outwardly upon the disk and body at one side of the slot, the projection of one interlitting in the corresponding recess of the other when the disk is against the lug.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.

EUGENE IVIET.
