HARNESS-SNAP.

SPECIFICATION forming part of Letters Patent No. 721,815, dated March 3, 1903.

Application filed March 22, 1902. gerial No. 99,474:- (No model.)

To ttZZ whom, it may concern:

Be it known that I, EGBERT L. MARANVILLE, a citizen of the United States, residing at Poultney, in the county of Rutland and State of Vermont, have invented a new and useful I-Iarness- Snap, of which the following is a specification.

This invention relates to snap-hooks; audit consists in a hook having a recess near the extremity or free end and with a recessed wheel or disk, of rubber or other suitable flexible material, mounted revolubly in a cavity in the shank of the device and adapted to engage the hook outside of the recess,wherebya yieldable closure is provided for the inlet to the hook, which will prevent the accidental removal of the strap or ring held thereby, and means provided for the protection of the disk from the back pressure from the ring or strap held by the hook.

The invention further consists in certain novel features of the construction, all as hereinafter shown and described, and specifically pointed out in the claims.

In the drawings illustrative of the invention, Figure 1 is a perspective of the device complete. Fig. 2is a longitudinal sectional elevation.

The body of the device consists of the shank or stock 10, having the usual loop 11 for the reception of the holding-strap, and with the backwardly-bent hook portion 12, of the usual shape. The point or free end of the hook is formed with a recess 13 in the under side just in the rear of its outer end, as shown, and in the stock 10, opposite this outer end, is located a recess or socket 14:, with a large opening at its inner end and with a smaller opening 15 at its outer end, as shown. Within this socket 14: is journaled a spur wheel or disk 16, of rubber or other suitable flexible material, with its points or teeth adapted to engage the under side of the end of the hook outside of the recess 13.

The portion of the hook outside the recess 13 engages the recesses in the disk 16, which thus serves to maintain the disk'against the ordinary back pressure 01' strains to which it would be subjected by the strap or ring from within the hook, but would yield to a force sufficient to remove the strap or ring.

The recess 13 is an important feature of the invention, as it forms a socket into which the strap or ring will be guided in event of any rearward movement caused by the slackening up of the strap or ring, so that all such back pressure or movement will be borne by the metal of the hook and the yieldable materialof the disk 16 relieved from all back pressure while in use. By this simple means the ring or strap held by the hook will not be accidentally detached when in use.

It will be observed that the extreme point of the hook 12 will at all times engage between two of the teeth of the elastic spur-wheel 16, so that the latter will be kept from accidental rotation or displacement. Reversely,when it is desired to either insert a harness-ring into or to remove it from the snap-hook it may be placed in engagement with the teeth of the said spur-wheel16,when by pressure exerted thereon the latter will be readily caused to yield in the desired direction. At no time are the teeth of the spur-wheel out of contact or out of engagement with the point of the hook, and accidental displacement of a ring from its engagement with the said hook is impossible.

The hook will be made of various sizes to adapt it to the various purposes for which snap-hooks are employed, as this device is adaptable to any snap-hook now in use.

The slot or opening 14, in which the spurwheel 16 is journaled, prevents the accumulation of obstructions, such as dirt or mud, which would be apt to settle therein if the said socket were closed at its lower end. The peculiar spur shape of the flexible wheel 16 also assists in removing any obstructions that may enter into the said slot.

The end of the hook 12 which engages the yieldable member 16 may be enlarged into a ball, if preferred.

Having thus described the invention, What is claimed is' 1. In a snap-hook, the combination with the slotted stock having a hook formed thereon, of a disk journaled in the slot of the stock and'having yielding, flexible teeth engaging the point of the hook, substantially as set forth.

2. A snap-hook comprising a slotted stock or body having a hook formed thereon and a ICO 10 such spur-wheel but permitting of the rotation of the latter by the yielding of the teeth thereof, substantially as set forth.

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

EGBERT L. MAR ANVILLE.
