BAG FASTENER.

Application filed July 1%,

To all whom it may conce/m.'

Be it known that we, desert-r Benzin and Louis BnRZoN citizens of the United States, residing at Fhiladelphia, county of Philadelphia, and State of Pennsylvania,

have invented a new and useful mprovement in Bag Fasteners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which forni a part of this specification.

Qur invention relates to bag fasteners adapted to secure the overlapping portions of bags together. v

The object of our invention is to provide fastener so constructed as to permit its various parts to be assembled without tools and with a. minimum of labor with the result that a considerable saving in manufacturing costs is effected.

Further objects of our invention are to provide a fastener of simple construction which will present an attractive appearance and which will be etlicient in operation, easily operated, and proof against derangement of its parts and consequent stickingv or failure in operation.

A variety of bag fasteners have been produced heretofore, but in the majority of cases they are o-f complicated construction and although their individuati parts are more or less readily made, the assembly of the parts presents a diilicult problem requiring the use of tools and a high degree of skill, with the result that the cost ofthe assembly step in the process of construction is relatively excessive. Further, Athe present forms of fasteners are prone to get out of order with the result that their operation becomes diiicult or impossible.

n accordance with our invention, we produce a. fastener which may be assembled without the use of tools by unskilled hands and with great rapidity; at the same time a fastener is produced which, because of its simplicity, is proof against error in assembly, or derangenient,'or sticking of its parts in operation.

Having now indicated in a general way the nature of our invention, its purpose and advantages, we will proceed to a detailed description of a. preferred embodiment 1921. Serial No. 484,533.

thereof, with reference to the accompanying drawings,` in which- 1 is an elevation of the upper portion of a hand bag embodying our invention.

Fig. 2 is a perspective view of a lock bolt and its carrying plate.

Fig. 3 is a yperspective view of a casing.

Fig. d is a perspective view of a retainer plate.

Fig. 6 is a view, partly in section7 of the complete fastener, in locked position.

Fig. 7 is a view, partly in section, of the complete fastener in unlocked position.

'F ig. 8 is a view looking upward at the bottoni of the fastener.

Figs. 9 and 10 are sectional views of a, modified form of our invention in open and closed positions respectively.

Fig. 11 is an inverted plan view Vof t-he modified forni partly broken away.

Fig. 12 is a plan view of the casing of the modified form.

Fig. 13 is an inverted plan of the bolt carrying plate of the modification partly in section.

The casing a, which may be of brass or any suitable material, is provided at each end with downwardly extending lugs b adapted to extend through suitable apertures in the overlying frame `c of the bag d and, when bent over aga-inst the under side of the frame, secure the casing to the bag.

The top of the casing is provided with a centrally located, longitudinally extending, narrow slot e and 'adjacent one end with a transversely extending slot The top adjacent lthe ends of slot f is raised to forni hiss g y rlhe curved locking bolt 7L is provided at one end with a hook z' adapted to engage suitable holding ineans and is secured at its other end to the under side of the bolt carrying plate j and centrally thereof. Obviously the locking bolt and plate may be formed integrally as shown in Figure 2.k The bolt carrying plate j is provided at one end with an extension bent into the forni kof a hook Zt' provided on its outside surface with a lug or protuberance m.

is a perspective view of a spring The retainer plate n is provided with a transversely extendingslot o adjacent one end with a centrally located longitudinally extending slot p, one end of which opens into the slot o.

The spring plate q is slit longitudinally and transversely to form the spring tongue fr which, in turn, is provided with a longi: tudinally extending slot s.

To assemble the various parts in their propel' relation, it is only necessary to place the bolt carrying plate on top of the casingivith the bolt 7L extending through the slot e and then hook i extending through the slot f between the raised portions of the top or lugs g, g. The retainer plate a is then inserted in the casing beneath the top, With the bolt extending through the slot p, and hook 7c is engaged in the slot 0, as shown in Figures 6 and 7.

The spring plate q is then placed in the casing beneath the retainer plate in such manner that the end of the spring tongue 1 will bear against hook /t' and the lug m with the bolt /t extending through the slot s. The Walls of the casing are then crimped as shown at z5, t, Figure 8, to secure the retainer plate and spring plate in the casing, the bolt carrying plate then is retained by the retainer plate and the assembly is coniplete.

The operation of the device will, it is thought, be apparent from an inspection of Figures G and 7 wherein it appears that the spring tongue r bears against the lug m in both the locked and unlocked position of the bolt 7L and tends to keep the bolt in one position or the other. The position of the bolt is shifted by manually raising or lowering the bolt carrying plate against the action of spring tongue r.

In the modification shown in Figs. 9-13, the slot c in casing a is extended to meet a transverse slot 0 and the intermediate plate a is dispensed with. ln this form the bolt carrying plate j is entered from the under side of the casing and hooks la prevent its passing entirely through slot 0 to engagement With the edge thereof.

The spring plate g', one end of which acts on the tail piece m formed at one end of the bolt carrying plate, is positioned Within the casing beneath the top thereof and may be secured to the top of the casing by lmeans of a rivet u.

y The operation of the modified device is similar to that of the device `of Figures l to 8 inclusive. The modified device is, however, simpler in construction and embodies fewer parts since the top of the casing is so formed as to perform the functions of the retainer plate which, as an independent element, may be dispensed with, and it will beunderstood in connection with the appended claims that the retainer plate need not be formed as a separate element, but may be formed as a part of the top of the casing.

Having now fully described our invention, What We claim and desire to protect by Letters Patent is:
