SNAP FASTENER.

Application filed May 20, 1925. Serial No. 31,544.

T rzZ whom, 'it may concern:

Be it known that we, HERMAN ll. (lorr- .MAN and STGMUND (lrrr'rnraii', both citizens of the UnitedStates, and residents of the city of `New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and `improved Snap AFastener, of which the following is a full, clear, and exact description This inventionrelates to snap fasteners.

An object of the invention is the provision of a simple and efficient economical snap fastener which is both flexible in its connection, and, at the same time, strong, being liable to the minimum extent to work loose.

The invention is illustrated in the drawing, in which Figure 1 is a plan view;

l? 2 is a seation through the fastener;

Fig. 3 is a side elevation of one ele-ment. of the fastener;

Fig. l is a side elevation of the other element. of the fastener.

The form of the invention shown in the drawing is a preferred form, although itis understood that modications in the construction and arrangement of the parts and in the character of the materials used may be adopted without departing from the spirit of the invention as set forth in the appended claims.

In its general aspect, the invention coinprises the interlocking engagement of two snap fastener elements, one of which is a plain loop of wire and the other of which is formed of two loops of wire, the end of one of said loops lying closely adjacent the end of the other and both being suflicently resilient so that the end of the first loop may be forced between the ends of the other two to form a tirm but flexible connection.

The invention is shown applied to the adjacent edges of two pieces of fabric, l0 and 11. The elements comprise metal plates l2 and 13 suitably fastened to the fabric and disposed adjacent the edges thereof. From one metal plate a loop of wire lei extends. This loop preferably extends out from the plate 1Q in substantially the same plane thereof. Extending outwardly from the other plate 13 are two loops of wire l5 and lo, the loop l in its length being shorter than the loop 16 and curved, and the longer loop 16 being` bent ever so slightly. The eno of the loop l5 lies close to the loop le with its extremity adjacent but extending not quite so far out as the end of the loop.

In interlocking the fastener elen'ients` the end of the loop .l-l; is forced betweeAL the two loops l5 and 16, as shown in Fig. 2, and the natural resiliency7 of these two loops causes them to grip the end of the loop nl firmly. It is also preferable that the width of the loop 1.41, as shown in Fig. l, be slightly greater than the width of the other two loops so that the elements can have a pivotal movement with respect to each other.

The present device, it will be obvious, simple and eflicient, strong and durable, and is made of such material that it can be manufactured for very low cost.

lll hat is claimed is:

l. A snap fastener device, comprising` a plate, a loop extending therefrom, a` secnd plate, two loops extending therefrom having their ends lying adjacent cach other I between which the end the other loop is forced, one of said last two-mentioned loops having its end lying close to but within the end of the other loop.

2. A snap fastener device, which com-y prises a plate, a metal loop extending there fr m, a second plate, apair of loops entendi ing therefrom and of different width than the first-mentioned loop, the two loops eX- tending from the second plate being slightly curved and one being of shorter length than the other, with the end of the shorter loop lying adjacent the longer end.
