EDWARD Y. ivroonn, or CLEVELAND, OHIO.

LOAD-HOOK.

Application filed April 10, 1915. Serial No. 20,392.

To all whom it may concern:

Be it known that I, EDWARD Y. Moonn, a citizen ofv the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,-have invented a certain new and useful Improvement in Load-Hooks, of which the following is a full, clear, and ex act description, reference being had to the accompanying drawings.

The object of this invention is to provide a swiveled hook for suspending loads from trolleys, hoists, etc., which shall have the capacity of supporting the load close beneath the swivel support of the hook. In many locations, for example on battleships, the minimization of head room is of vital importance; at the same time, it is desirable to provide a swiveled hook for the easy attachment and manipulation of the load. My invention provides a hook admirably adapted for this purpose and so arranged that the load may be brought clear up against the swiveling eye of the hook, While the weight stress is directly downward and has no tendency to cause any lateral binding of the hook on its supporting swivel.

In accomplishing the result, I have provided a supporting eye, on the shank of which is swiveled a block having hooking portions on opposite sides of the shank located above the supporting bearing of the block on the shank. With such a device any suitable flexible loop may be passed around the article to be supported or raised and hooked over the two arms of the block, holding the article close to the under side of the block. My invention is hereinafter more fully explained and its essential characteristics are summarized in the claims.v

In the drawing, Figure 1 is a side elevation of my load hook; Fig. 2 is a plan thereof; Fig. 3 is an end view; Fig. dis a vertlcal central transverse section.

As shown in the drawings, A designates the swiveling eye. This consists of an eyeportion a and a shank a which are preferably one integral piece. B designates the block, which is swiveled on the shank a This block consists of an elongated member, from the lower portion of which rises a central boss I), and two hooks b on diametrically opposite sides of the boss and spaced therefrom. The boss 2) has a central cylindrical vertical bore 5 surrounding the shank a and below this bore is an' enlarged cavity 6* extending to the base of the block. Wltlle i in the cavity 6 is a collar C firmly secured to theshank a and thus effectively locking the block to the eye piece while swiveling it thereto; I The eye-portion aclosely overhang's'the' topof the boss and thus prevents downward movement of the shank with reference to the block.

I The collar C is shown as snugly surrounding a reduced portion a of the shank and as clamped in place by the lower end. of the shank beingupset beneath the collar. The lowerface of the collar may be chamfered inwardly, as at 0, and the upset portion a ofthe shank may thus be countersunk Within the collar.

It will be seen that the construction described provides a double hook swiveled on an eye-piece and not extending below such iece. I prefer to make the lower face of the block, the lower edge of the collar, and the lower end of the eye-piece shank all substantially flush with each'other, as shown. The boss portion '1) which surrounds the shank may conveniently be provided by a side swell or protuberance b of the block. The two spaces on opposite sides of the boss between it and the hooks 12 it will be seen, are adapted to receivethe upper ends of any suitable rope, chain, strap, sling or loop to carry the load. The bottom portion of this space, that is the top of the block body between the hook and boss, is preferably convex upwardly or rounded in a transverse direction, as shown at b to most conveniently accommodatethe supporting flexible member.

The, hook described is cheaply constructed. For example, theIeye-m ember may be a drop forging and the block a steel casting. When assembled, the parts are effectively secured together while allowing the block to easily swivel on the eye. In use, the load may be secured close to the block, even substantially in contact with it or with the lower end of the eye shank. By making the hook double on opposite sides of the shank, V

the stress of the load is directly downward and is thus carried by the collar C and from thence to the shank and eye, so that there i no tendency to tip the device.

Having thus described my invention, what I claim is: 1. In a load hook, the combination, wit a supporting member having a top eye and a vertical shank, of a block swiveled on said shank and provided with an upwardly pro jecting central boss freely surrounding the shank, and a pair of upwardly projecting hooks on opposite sides of the boss and spaced therefrom, the central under portion of said block having a recess, and a collar on the shank comprised within said recess, whereby the block is supported by the shank, and said collar on the one side and the overhang of the eye on the other locks the supporting member within the block.

2. The combination of an eye having a shank with a reduced lower portion, a block having a continuous lower body portion and a central upwardly extending boss and a pair of upwardly extending hooks on diametrically opposite sides of the boss, said block having a cylindrical opening through said bOSs surrounding the shank and having a recess of larger bore beneath the opening and extending therefrom to the lower face contained within the recess in the block and clamped in place on the shank and in the recess by means of the shank being upset beneath the collar, the eye at the upper end of the shank closely overhanging the top of the boss and preventing downward movement of the shank with reference to the block.

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

EDWARD Y. MOORE.
