BAG-JAW FASTENER.

. Patented June 15, 1915.

Application filed March 8, 1315. Serial No. 12,789.

To all whom it may concern: 7

Be it known that I, Louis B. PRAHAR, a citizen of the United States, and a resident of Massapequa, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Bag-J aw Fasteners, of which the following is a specification. v

This invention relates to certain improvements in fasteners of a type adapted for use in detachably holding together the jaws or frame parts of a handbag, pocketbook, or valise, or other similar article. c

My improved device is of that type in which there is a knob which may be tilted to release the fastening and permit the sepa ration of the frame parts, the knob being normally heldin the desired fastening position' by a suitable spring within the frame part.

-My invention relates particularly to the construction of the knob and catch portion and the main object of the invention is to simplify the construction, reduce the cost of manufacture and strengthen the parts so as to reduce the liability of the parts being bent by pressing the knob too far in opening I th bag or other article to which the fastener est 15 connected.

Reference is to be had to the accompanydrawings forming a part ofthis application and in which similar reference characters indicate corresponding parts in the several views.

In these drawings, Figure 1 is a side elevati on of a bag or pocketbook frame having a fastener constructed in accordance with my invention; Fig. 2 is a view similar to a por tion of Fig. l but on an enlarged scale and showing certain of the parts partially broken away; Fig. .3 is a transverse section on the line 3-3 of Fig. 1, and Fig. 4 is an inverted plan view of the fastener removed from the frame.

I have illustrated my invention as applied to a type of bag jaw in which there are two frame members 10 and 11 each substantially in the form of a channel with the parallel side flanges of the two channels extending in the same direction and adapted to receive the edge of the fabric, rial forming the body portion of the bag or pocketbook. The webs of the two channels constitute the outer edge portions of the rains members and the "f secured by suitable pivots 12. This type of leather or other materame members are bag jaw is old and common in the art and forms no portion of my present invention. I have merely illustrated my invention as applied to this type of bag jaw and it is therefore evident that various changes could be made in the construction of the jaws or frame and that my invention might be applied to other types of jaws or frames.

In the specific form illustrated, my improved fastening device is formed of two sections 13 and 14 rigidly secured together. The section 13 is in the form of a shallow cup having a top wall 15 and a peripheral wall 16. he peripheral wall 16 at one point along its length has an extension or flange integral therewith and folded so as to form a loop 17 projecting downwardly from the free edge of the cup. The terminal portion 18 of the strip of metal constituting the extension and forming the loop is disposed within the cup and is bent at right angles to the general direction of the loop so as to engage with and lie flat against the top wall 15 of the cup-shaped section. The loop is designed to pass through a slot in the web portion of the channel constituting one of the frame members-so that the body of the oop is within one of the channels. Here, a torsion spring 19 extends through the loop soas to prevent the latter from being withdrawn from the slot. The spring is so twisted as to tend to swing the opposite edge of the cup-shaped member 13 down into en- ,gagement with the other frame member 11.

It may here engage with the frame member in any suitable manner so as to effect a fastening. As shown, a small portion of the frame member 11 is struck upwardly to form a lug or shoulder over which the free edge of the wall 16 of the cup 13 may engage so as to prevent the separation of the two frame members. It is of course evident that any other form of inter-engagement of the two parts may be employed, such for instance as providing the edge of the cup with a small tongue or projection entering a recess in the frame member 11 or engaging with the outer surface of the outer side flange;

The member 13 above referred to is formed of sheet metal while the member 14: may be of any suitable construction or may be entirely omitted. As shown, it is turned from a single block of metal and has a base engaging with the outer surface of the top wall 15 of the member 13. A central stud 2O thereon projectsthrough apertures in the wall 15 and the terminal portion 18 of the loop forming strip. The stud is slightly longer than the combined thicknesses of these two layers of sheet metal so that at its inner end it may be swaged'or bent over to rigidly and permanently connect the two parts together. The body portionof the member 14: may be of any suitable or desired ornamental design and may be of any shape, size or configuration desired. It is merely, necessary that it provide a sufficiently large gripping surface to enable the cup-shaped member 13 to be tilted against the action of the spring. If the knob ltbe omitted, the stud should still be retained or replaced by an ordinary rivet which might be on the side of the cup-shaped member instead of on the top.

In the specific construction illustrated, the cupshaped member 13 being very shallow may be easily stamped from sheet metal without drawing the metal to only a slight extent. By extendingthe strip. of metal forming the loop back into the eup-shaped member and there securing it, the portion extending through the slot is; reinforced and any tendency to bend or break the metal at the point where, it passes through the slot is resisted by Bv terminating the loopfiorming strip fiat against the inner surface of the top wall of 1 the cup shaped member,

the said top wall is reinforced and the liability of the riveted I elaimas new and desire or swaged end of the stud pulling out is materially reduced. Furthermore,. thinner metal may be employed 'asthe top wall is less liable to bend under twisting strain app i d. t he Outer P r i n b th mem ber 14:.

Hav ng thus described my invention, what to Secure y ters Patent is:

1. The combination with a pair of jaws, one of which has a slot therein, of a fastenhaving interlocking and proj ectin g through the doublethiclmess of metal;
