SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 489,502, dated January 10, 1893.

Application filed September 16, 1892- gerial No. 446,047- (No model.)

To aZZ whom it may concern..-

Be it known that I, HUBERT P. RICHARDS, of New Britain,in the county of Hartford and State of Connecticut, have invented certain new and useful Improvementsin Snap-Hooks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

My invention has for its object to provide a snap hook of novel construction which shall be particularly adapted for use as a cast off for suspenders.

In the accompanying drawings,Figurel represents a front view of myimproved snap hook applied to the loop of the locking tongue of a suspenderbuckle. Fig. 2is an edge view of the snap hook detached, the device being shown somewhat enlarged. Fig. 3 is a rear view of the same. Fig. ialongitudinal sectional view taken on the line :r-m, Fig. 3. Fig. 5 a similar view with the locking tongue moved away from the point of the hook. Fig. 6 is a view of the blank from which the body of the snap hook is constructed. 7 Fig. 7 is a view of the blank from which the locking tongue is formed. Fig. 8 is a perspective view showing the form which the blank shown in Fig. 6 assumes after being subjected to the action of the dies, and Fig. 9 is a similar view of the completed looking tongue.

Similar letters denote the same parts.

The main body of the device is formed from a single piece of metalA and comprises a loop a for the attachment of the suspender ends, an opposite elongated portion turned back on itself to form a hook b for engaging the ring or eye of the suspenderbuckle,a spring tongue 0 struck out from the body of the metal and adapted to act upon the locking tongue, as will be presently described, a slot or opening d formed by striking out the spring tongue c,

and a short projection e which serves as the fulcrum of the locking tongue B. The looking tongue B is preferably made broad at its rear end f to constitute a convenient finger piece for operating it while its outer end g, which is adapted to co-operate with the point of the hook b, is narrowed and shaped so as to fit within the slot or opening din the main plate when the tongue is pressed fully back as, shown in Fig. 5, and thus permit the ring or eye of the buckle to pass over the hook without obstruction. An aperture h is formed in the tongue for receiving the short projection 6 of the main plate A, as shown in Figs. 4, 7 and 8.

In assembling the parts, the spring tongue 0, (shown best in Fig. 8) is slightly raised so as to permit the narrowed end 9 of the looking tongue to be inserted from the rear through the slot or opening until the aperture in the locking tongue comes opposite the short projection e, whereupon the said proj ection is fitted into said aperture, after which the spring tongue is caused to assume its operative position so that it will bear with pressure upon the locking tongue above its hinging point and force the end 6, outwardly against the point of the hook. The end portions 0 c of the spring tongue 0, shown particularly in Fig. 8, are preferably turned inwardly and bear upon the locking tongue just in front of a shoulder i, formed upon the said locking tongue. By this construction the spring is enabled to act effectively and the locking tongue is prevented from working off the projection e by any possibility.

The snap hook described is particularly adapted for use as a cast off for suspenders though it is of course susceptible of other uses. The finger piece or outer end of the locking tongue occupies a position where it is most natural for the finger to rest when grasping the device and hence the locking tongue is released almost unconsciously by the wearer when the device is grasped to unlock it.

Having thus described my invention what I claim as new is:

1. In a snap such as described, the combination with the body struck up from sheet metal with the hook and loop at opposite ends the internal spring tongue and a central opening, of the locking tongue passing through the central opening co-operating with the spring tongue and with its forward end engaging the end of the hook and the rear end forming a finger piece, and the lug or projection extending into the central opening and pivotally uniting the tongue and body of the.

hook, the spring tongue having the inturned bifurcated end and the short projection struck up from the body of the hook forming the central opening, of thelockin g tongue passing through the central opening and provided with the aperture for receiving the short projection and co-operating with the bifurcated ends of the spring tongue; substantially as described.

HUBERT P. RICHARDS.
