HENRY S. SEELY, OF HAMMONTON, NEW JERSEY.

SNAP-HO OK.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed February 2, 1907. Serial No. 355,491.

To all whom it may concern:

Be it lmown that I, HENRY S. SnnLY, a citizen of the United States, residing at Hammonton, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Snap-Hooks, of which the following is a specification.

The present invention relates to an improvement in snap hooks, the object being to provide an article of this character which is simple and durable in construction and which can be readily manipulated to quickly connect or disconnect two straps or similar tension members.

A further object is to provide a snap hook which is peculiarly designed so that the tension in the straps will automatically pull the same apart when the catch upon the snap hook is released.

For a full understanding of the invention and the merits thereof and also to aquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a snap hook constructed in accordance with the invention. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a bottom plan view. Fig. 4 is an end view of the snap hook, portions being broken away.

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

The body portion of the snap hook is in the nature of a sleeve 1 within which the extremity of one of the straps 2 is permanently secured in any suitable manner such as by the rivets 3 indicated in the drawings. One side of the sleeve 1 is provided with the spaced and integral extensions 4, the extremities of which are formed with eyes 5 for the reception of the cross bar 6 upon which the tongue 7 is pivotally mounted.

In the preferred formation of the invention, the sleeve 1 can be stamped from sheet material, the ends of which are bent so as to overlap each other and connected in any approved manner as by the rivet 8. When thus formed it will be readily apparent that the extensions 4 can be readily stamped integral with the sleeve 1 and that the eyes 5 at the extremities thereof may be formed by looping the said extensions.

The tongue 7 is shown as formed from a single piece of spring wire which is bent back upon itself at an intermediate point, the end portions of the wire being extended laterally to form the offset portions 9, while the extremities are coiled at 10 to form eyes for the reception of the cross bar 6. The swinging end of the tongue 7 normally bears against the exterior of the sleeve 1 and is designed to be engaged by a keeper 11 which is in the nature of a loop surrounding the sleeve 1 and loosely connected to the bottom thereof. In the present instance this connection is accomplished by means of a plate 12 secured to the sleeve and having a groove pressed outwardly therefrom for the reception of the keeper. The end of the tongue 7 engaging the sleeve 1 is bent outwardly as indicated at 13 and has a spring ac tion which normally prevents the keeper 11 from being disconnected therefrom. With this construction it will be apparent that in fastening the tongue 7, the same is swung into engagement with the sleeve and the outwardly bent end 13 thereof then sprung inwardly against the sleeve 1 until the keeper 11 can be slipped thereover, the pressure being then released to permit the end of the tongue to spring outwardly in such a manner as to normally prevent the keeper from being disengaged therefrom. This tongue 7 is designed to receive a ring or loop 14 secured to a second tension member 15, and when in normal position said ring is pulled against the offset portion 9 of the tongue 7 and tends to swing the same away from the sleeve 1. Owing to this fact it will be apparent that when the keeper is pushed over the extremity of the tongue 7 the pull of the ring 14 upon the offset portion 9 will automatically cause the tongue to swing about its pivot and assume such a position that the ring 14 will readily slip therefrom.

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

1. In a device of the character described, the combination or a sleeve, extensions projecting from the sleeve, a tongue loosely connected to the extensions, and a keeper normally holding the tongue against swinging movement.

2. In a device of the character described, the combination of a sleeve, an extension projecting from the sleeve, a tongue loosely connected to the extension and designed to be swung toward the sleeve, and a keeper carried by the sleeve and having a spring engagement with the tongue to normally hold the same against swinging movement.

3. In a device of the character described, the combination of a sleeve, an extension projecting from the sleeve, a tongue formed of spring material and loosely connected to the extension and designed to be swung toward the sleeve,

' the extremity of the tongue being bent outwardly, and a keeper carried by the sleeve and having a spring engagement with the outwardly bent portion of the tongue and normally holding the same against swinging movement.

4. In a device of the character described, the combina tion of a body portion, an extension projecting from the body portion, a tongue loosely connected to the extension, the swinging end of the tongue being bent outwardly and designed to swing toward the body portion, and a keeper carried by the body portion and having a spring engage ment with the outwardly bent end of the tongue to hold the latter against swinging movement.

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