BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 309,785, dated December 23, 1884. Application filed April 28,1884. (No model.)

To all wlw/n, it may concern:

Be it known thatI, ELLwooD Ivins, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Combined Button and Fastener, of which the following is a specification.

My invention relates, mainly. to that class of button-fasteners in which a staple having prongs adapted to pass through openings in the button is combined with a retainer, around which the ends of said prongs are clinched after passing through the button and the cloth to which it is to be attached.

The object of my invention is to prevent the prongs from being straightened out and pulled through the cloth by excessive strain upon the button, and this object I attain in the following manner, reference being had to the accompanying drawings, in which- Figure l is a perspective view of a button, staple, and retaining-ring constructed in accordance with my invention; Figs. 2 and 3, sectional and Figs. et and 5 rear views shoving the method of securing the button by the staple and ring, and Figs. (i to 9 modified forms of retainer.

A is a button, having in the present instance four openings, a, for the passage of the prongs b of a staple, B, although more or less than this number of prongs and openings may be used, if desired. Each prong b has a straight shank terminating at the spear-point c, and has abrupt shoulders ff.

D is the rctaining'ring, inthe outer edge of which 'are as niany recesses d as the staple has prongs, each recess heilig of a width slightly in excess of the width of the shank of the prong, but less than the width of the spearpoint c of the same. lVhen the staple is applied to the button and its prongs passed through the cloth x, said prongs are outside of the ring D and in line with the recesses d of the same, as in Figs. 2 and 4, so that when the ends of the prongs are bent inward by the clinching device, as in Figs. 3 and 5, the shanks of the prongs enter the recesses, and any outward pull upon the prongs caused by strain upon. the button will canse the shoulders f of the spear-heads e to come in contact with the ring, and thus prevent the withdrawal of the prongs. A notched disk, Fig. 6, may be used in place ofthe ring D, if desired; but the ring is preferred, as it permits the more effective clinching of the prongs; but when the ring is used the inner edge of the same may be notched, as shown in Fig. 7, the prongs b 1n this ease being clinched outwardly instead of inwardly.

Instead of a ring having a central opening with which the notches communicate, the retainer may be made in the form of a disk with a series ot openings, one for each notch, as in Fig. 8, these openings being large enough 1n diameter to permit the passage of the spearheads of theprongs, and this construction being included in the term edge notches.

My improvement can'also be applied to that class of buttons in which the securingprongs are struck up from the back of the button, instead of forming part of a separate staple, an instance of such a but-ton being shown in Fig. 9. C

As regards the prior state of the art, it should be stated that button-fastening prongs have been inade with spear-like ends, but were not made with abrupt shoulders or used in connection with a retainer, as in my invention.

Button fastening staples have also been made with two elastic pointed shanks, each having an abrupt shoulder7 as in Patent No. 56,612; but in this case the hold of the staple on the removable button was due to the elasticity ofthe shanks, whereas in my invention the shanks are bent into notches in a retainer, the spear-heads overlapping the saine, so as to form a permanent fastening.

I therefore claim as my invention- The combination of the perforated button A on one side of the fabric, the retainer D, arranged on the opposite side, and having the recesses d. with the staple B, having prongs,

veach of which consists of a shank terminating in a spear-head and having abrupt shoulders, theshank of eacl-f prong being bent into a recess of the retainer, and the spear-headover the saine, as set forth.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.

ELLWOOD IVINS.
