WILLIAM C. HIERING, OF NEWARK, NEW JERSEY, ASSIGNOR TO 5. E. MERGOTT 00., OF NEWARK, NEW JERSEY, A OGRPQRATION OF DELAWABE.

BAG FASTENER.

Application filed April 23, was. Serial No. 708,331.

This invention relates to improvements in fasteners as applied to the frames of valises, hand bags, pocket books and the like and has as one of its objects to provide a simple, neat and effective fastener made of a single piece of material stamped and shaped in an inexpensive manner.

Another purpose is to provide a fastener having self snap-locking means whereby the bag frame sides are held in positive fixed engagement until manually released.

A further aim is in the provision of a bag fastener applicable to a wide range of frames without mutilation or disfigurement and in which the body of the fastener is not weakened by use or damaged by the expenditure of unnecessary energy in operation.

These several aims and objects are accomplished by the novel and practical construction and arrangement of parts hereinafter described and shown in the accompanying drawing forming a material part of this disclosure, and in which Figure 1 is a fragmentary rear side view of a conventional type of bag frame, showing the application of the invention.

Figure 2 is an enlarged transverse sectional View of the same, the section being taken on line 22 of Figure 1.

Figure 3 is a top plan View of the fastener in detail.

Figure 4 is a rear elevational View of the same.

Figure 5 is a bottom plan view thereof.

Figure 6 is a plan view of the blank prior to bending into its completed shape.

Referring more minutely to the drawing, the bag frame sides are designated by the numerals 10 and 11, respectively rear and front, the former having a forwardly extending lip 12 overhanging the edge of the front side, this lip being formed by closely doubling the material of the side frame, both of which are of U-shaped construction and, as will be understood, are hingedly engaged at their parallel, end extremities.

The front frame side 11 is pierced through its upper edge, as at 13, to produce a pair of upstanding prongs lt equally spaced from the center, and the rear frame side 10 is provided in its upper edge with a pair of elongated openings 15.

The fastener is formed from a single blank, shown in Figure 6, to present a graceful arcuately curved top plate 16, and oblong rectangle in profile, having end walls 1'? and a rear wall 18 level therewith adapted to seat closely upon the outer surface of the rear side frame 10.

A re-entrantly curved element 19 connects the front edge of the plate 16 integrally with the catch plate 20, the same rearwardly and slightly below the level of the end and rear walls to engage the prongs 14: of the front frame side when the device is in operative position, as best shown in Figure 2.

Extending down from the lower edge of the rear wall 18 are a pair of spaced elements 21, turned re-entrantly upward as at 22 their upper ends being connected by an integral bar These elements present a pair of flattened loops 24: adapted to pass freely through the openings 15 and receive within them the correspondingly flattened portion 25 of a torsion spring 26, the offset head 27 of which abuts against one of the walls of the rear side frame 10.

The action of this spring is to press the fastener body tightly downward, holding the plate 20 in engagement with the detent prongs 14, the spring flexing when a raising pressure is applied to the forwardly project ing portion of the fastener, as in opening the bag, and also when the sides are snapped shut or pressed together, it being understood that the width of the openings 15 is sufliciently in excess of the combined thicknesses of the elements 21 and 22 to permit the fastener to be readily raised in releasing the frame sides.

It is to be noted that the elements 22 are disposed on the outer surface of the wall 18 and that no tendency for disruption occurs when the fastener is raised in releasing the sides; this is contradistinction to such structures as have their corresponding elements arranged interiorly of the fastener body.

The bar 23 is preferably bowed slightly outward or away from the rear wall 18 in order to provide eflicient drainage of the chemicals used in coloring or plating the fasteners, but the elements 22 may be secured to the wall by soldering or brazing, thus further re-enforcing the structure.

Experience has determined the utility of the structure and demonstrated its advantages over those in common use, while its simplicity and economy in manufacture are believed obvious.

Although the foregoing is descriptive of a preferred embodiment of the invention, it will be understood that minor changes in construction, proportion and shape may be made well within the spirit and scope of the appended claims.

Having thus described my invention what I claim as new and seek vtosecure by Letters Patent, is

1. A bag fastener comprising a convex oblong rectangular plate having flanged rear and end ed 'es and an inclined catch element at its front edge, a pair of flattened loops depending from the rear -flange, the outer members of said loops being fixed on the exterior of said rear flange at the center thereof, said loops passing freely through openings in one of the bag frame side members, a bar integrally connecting the outer elements of said loops, means internal of said frame member, engaging said loops whereby said catch element is normally drawn into operative contact with the mating bag frame member and a forwardly projecting lip on the first named frame overlying the edge of the other frame.

2. In combination with a pair of hingedly engaged, channelled franiies, of a fastener hingedly mounted lengthwise on one of said frames, two flattened loops extending in spaced relation inwardly through the last named frame, the outer elements of said loops being secured to the rear of :said fas tener at its center, an outwardly curved bar extending between the ends of said loop elements, said bar acting as a re-enforcement and limiting the movement of the fastener, a torsional spring carried in said frame element engaged in both of said loops, upstanding prongs on the other of said frame elements, means formed on said fastener adapted to engage said prongs when the frame elements are closed, and a projection integral with the first named frame to contact with said prongs.

3. A bag fastener comprising a convex 0blong rectangular plate having flanged rear :and end edges and an inclined catch element at its front edge, a pair of flattened loops depending in spaced relation from the rear flange. at the center, the outer rc-eutrantly turned members of said loops being .ed on. the exterior of said rear flange, constituting a re-enforcement therefor, an out :a rdly curved bar integrally connecting the loops acting as a stop limiting the rise of said fa tener; said loops passing freely through appropriate openings in the bag frame, integral prongs on the mating; bag" frame member, means carried in the bag frame adapted to engage said loops whereby said catch is normally held in position to engage the prongs on the mating: bag frame member and a doubled forwardly projecting lip integral with the first named bagframe member adapted to overlie the mating member .and re-enforce said prongs when the bag frame is closed.

This specification signed and witnessed this 22nd day of April, 1924:.
