UNITED STATES PETER GRUNSTRA, 0F CLIFTON, NEW JERSEY.

BUTTON FASTENER.

Application filed March 7, 1925.

To all whom it may concern:

Be it known that 1, PETER GnuNs'rRA, a citizen of the United States, residing at Clifton, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Button Fasteners, of which the following is a specification.

This invention relates to improvements in button fasteners, and more particularly to an improvement over my button fastener embodied in my copending application, bearing Serial No. 4,792, filed January 26, 1925.

One of the important objects of the present invention is to provide a button fastenor wherein means is provided for securing the button fastener on a garment against accidental displacement therefrom.

A further object is to provide a button fastener which may be easily and quickly assembled 0r secured on a garment without using any sewing thread.

Other objects and advantages of this in vention will become apparent during the course of the following description.

In the accompanying drawing, forming a part of this specification, and in which like numerals indicate corresponding parts throughout the several views:

Figure l is a view, partly in elevation, and partly in section of the button fastener embodying my invention, showing the same in assembled relation.

Figure 2 is a sectional view, tpken approximately 011 the line 22 of Figure 1.

Figure 3 is a top plan view of the upper disc showing the inner adjacent ends of the locking pins, and

Figure l is a detail perspective view of one of the locking pins.

In the drawing, wherein for the purposeof illustration is shown the preferred embodiment of my invention, the numeral 1 designates a button of any conventional construction, the same being provided with the looped shank portion 2. The fastener comprises the ring like member 8 formed of resilient material, the free ends 4: and 5 re spectively thereof, being disposed in parallel abutting relation. The parallel disposed free end portions l and 5 are provided with the notches 6 and 7 respectively, and the purpose thereof will be presently apparent. I

The holder for the ring like member 3 Serial No. 13,801.

comprises a cylindrical member 8, the same being provided with a central opening 9, in which is adapted to be disposed the parallel abutting

free end portions

4 and 5 of the ring like member 3. The opening 9 is substantially oval-shaped as clearly illustrated in Figure 2 of the drawing. The cylindrical member 8 is further provided with a pair of diametrically opposed openings 10 and 11 respectively, the openings being disposed horizontally and communicating at their inner ends with the central opening 9. The outer ends of the openings are slightly enlarged, as clearly illustrated in Figure 2.

A pair of locking pins are adapted for slidable movement within the respective horizontally extending openings. Each of the locking pins is of substantially T-shaped design. The shank or leg portion of each of the substantially T-shaped locking pins is bevelled at its free ends, as illustrated at 14. The

locking pins

12 and 13, which are disposed within the openings 10 and 11 respectively will have their inner opposed bevelled ends cooperating with the notches 6 and '7 respectively, for locking the free end portions of the ring like member 3 in the cylindrical holder 8. The arms of each of the T-shaped locking pins are adapted for movement within the enlarged outer ends of the horizontally extending openings.

A fiat spring band 15 extends around the peripheral edge of the cylindrical holder 8, the free ends of said spring band being arranged in overlapping relation. he spring band 15 engages the head portions of the 'l'shaped locking pins and normally urges the latter into locked engagement with the notches provided in the free end portions eland 5 of the ring like member. It is of course to be understood that when the ring like memberis assembled with respect to the cylindrical holder, the bevelled lower ends of the free end portions will engage the bevelled faces l l of the T-shaped locking pins and move the same outwardly against the tension of the flat spring band 15, so as to permit the parallel abutting free end portions of the ring like member to be disposed within the central opening 9 of the cylindrical holder. 7

Then the notches 6 and 7 are in alignment with the inner ends of the llLOl'lZOlltill ly extending openings, the bevelled inner ends of the slidable locking pins will be forced into engagement with the respective notches, thereby securely holding the ring like member in position within the cylindrical holder 8.

The means for securing the holder 8 on a garment comprises the upper and lower discs 16 and 17 respectively. The lower disc 17 is formed on the bottom of the cylindrical holder 8, whereby a unitary structure is provided; the upper disc 16 being adapted to engage the upper face of the holder. In attaching the holder on a garment, it is of course to be understood that a suitable opening is formed in the garment for receiving the cylindrical holder 8. The discs, which are formed preferably of sheet metal and are of a greater diameter than the diameter of the cylindrical holder 8 are clearly illustrated in Figure 1. Furthermore, the discs are provided with central registering openings which are of the same shape as the central opening 9 formed in the cylindrical holder 8, these openings being in registry with each other, so as to permit the ready and easy insertion of the free end portions at and 5 of the ring like member with respect thereto. The edges of the discs 16 and 17 are provided with the

protuberances

18 and 19 respectively, the same being struck out from the discs. These protuberances form gripping teeth, and are adapted for engagement with the material of the garment on which the button is to be fastened. The teeth 18 formed on the upper disc 16 are disposed between the teeth 19 formed on the lower disc 17, the gripping teeth being further arranged in annular spaced relation on each of the discs. The upper plate 16 is adapted to be disposed adjacent the outer side of the cloth, whereas the lower plate 17 en gages the opposite side of the cloth.

It will thus be seen from the foregoing description that a button fastener has been provided, wherein the parts are of such construction as to enable the same to be readily and easily assembled and secured on a garment, without using sewing thread, such as is commonly used in securing a button on a garment. The simplicity with which the present device is constructed, renders the same inexpensive in its manufacture, yet strong and durable.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the appended claims.

hat I claim is:

1. In a fastener for a button, wherein the latter is provided with a looped shank por tion, a resilient ring like member adapted to receive said looped shank portion, the free ends of said ring like member being disposed in parallel abutting relation, a
