JEFFERSON BAR-RY, OF AVOCA, MICHIGAN.

SNAP-HOOK.

To all whom t may conce/ra Be it known that l, JEFFERSON BARRY, a citizen of the lUnited States, residing at rivoca, in the county of St. Clair and State of Michigan, have invented certain new and useful improvements in Snap Hooks, of which the following is a specification.

rlhis invention has relation to snap hooks especially designed to be used upon the neck yokes of harness, but which may be used advantageously in other capacities.

rlfhe object of the invention is to provide a snap hook of simple and durable structure only embracing a minimum number of parts and having these parts so arranged that they cooperate with each other in maintaining their proper relations and positions, and at the same time affording a secure and durable structure.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which:

Figure l is a longitudinal sectional view of one form of the hook; Fig. Q, is an edge elevation of the same; Fig. 3 is a transverse sectional view of the same cut on the line 3-3 of Fig. l.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The hook consists of a frame 1 which is preferably formed up from rod or may be in the form of a forging. The frame is provided at one end with an eye 2. rlFhe frame l is provided at one side and near the end provided with the eye 2 with an opening 3 through which the snap ring is adapted to be inserted. A flat spring 4 is secured against that side of the frame l having the opening 3 and lies between the opposite sides of the said frame with its free end portion bridging the opening 3. rllhe inner face of that side of the frame l having the recess 3 is recessed as at 6 to receive the spring 4 so that its inner surface is approximately in alinenient with the inner surfaces of the end Specification of Letters Patent.

portions of the side of the frame to which it is attached. it detent 7 is slidably mount ed in the longer portion of that side of the frame l which is provided with the opening 3, and the said detent is provided at its inner end with an enlarged head 8 which lies between the side of the frame l and the spring 4. rlhe said spring holds the said detent in place with its outer end projected slightly beyond the outer surface of the side of the frame l. r.lhe hook is adapted to receive a ring, indicated at 10. 'llhis ring is placed in position in the hook by forcing its side laterally against that portion of the spring 4 which bridges the opening 3, whereby the free end portion of the said spring is depressed and carried away from the inner surface of the frame l. rllhus the said ring may be slipped in beyond the free end of the spring 4 and may then move longitudinally of the hook and engage the end thereof opposite that end at which the eye 2 is located.

A block ll is inserted in the end of the hook remote from the eye 2 and bears against one end of the spring and efectually holds the same in position. Any suitable means may be provided for holding the block ll in position, but preferably the said block is secured by upsetting or slightly spreading its ends, whereby they slightly overlap the inner side portions of the frame and the end of the spring and secure the parts. rEhe addition of this block adds materially to the strength of the work for the reason that it forms an additional thickness of metal against which the ring may bear when in position, thus relieving the end of the hook remote from the eye 2 of strain applied through the said ring.

Having thus described the invention, what is claimed as new is:

it hook comprising a frame having spaced side portions one of which is provided with an opening, a flat spring lying against the inner surface of the side portion having the opening and bridging the said opening, a block inserted between the opposite side portions of the frame at one end thereof and securing In testimony whereof, I affix my signalsoaidd spifring in position and protecting4 the ture in presence of two witnesses.

en o the hook and a detent sidably mounted in that Siide of the frame having JEFFERSON BARRY' [L'S] the opening and bearing at one end against Witnesses: the spring and located between said opening F. A. HILL, and said block. GEORGE D. K001i.
