BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. 321,665, dated July 7, 1885.

Application filed May '7, 1885. (No model.)

To osZZ whom it Trtay concern:

Be it known that I, Janus F. THAYER, a citizen of the United States, and a resident in the city and county of Providence, and State of Rhode Island, have invented an Improvement in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawin representing like parts.

This invention has for its object to provide a fastener of new and improved construction and adapted for use as a button-fastener to secure buttons to fabric, or as a lacing hook or stud, or to serve as a fastening hook or button for gloves and the like; and the invention consists, essentially, of a fastener cut from folded sheet metal and having sides or halves substantially parallel and integral with each other, each half having one or more penetrating prongs, and the said halves being joined at their tops, the folded edge of the sheet metal from which the fastener is cut constituting the neck or connecting portion of the halves, as more fully set forth in the following description, and particularly poi ntcd out in the claims.

Figure 1 is a perspective view of a strip of folded or doubled sheet metal from which my improved fastener is cut; Fig. 2, asimilar view of a fastener adapted for use to secure buttons to fabric; Fig. 3, a sectional view showing the fastener as applied to secure a button to fabric; Fig. 4, a plan of the under side of the mate rial, to clearly show the penetrating prongs as clinched; Fi 5, an elevation of my improved fastener adapted for use as a lacing hook or stud; Fig. 6, a similar view showing the form of fastener suitable as a glove fastener or button, and Fig. 7 a modification showing a second form of button-fastener. Fig. 7 shows in end and side elevation a fastener adapted to secure a but-ton to fabric and to receive the shank-eye of the button on its shorter arm, while the longer arm, constitutingtwo prongs, may be forced into and clinched to the material, the said shorter arm being adapted to rest on the mat rial to prevent the removal of the button.

In carrying out my invention I take astrip of sheet metal, of suitable thickness and width, and fold or bend it through its longitudinal center to provide a folded or doubled strip, A,

from which I stamp or cut my improved fast-- ener, consisting, essentially, of substantially parallel or adjacent sides or halves, each half having one or more penetrating prongs, the folded edge a of the double strip A constituting the top or connecting portion 2 ofthe halves of the fastener.

The fastener shown in Fig. 2 is cut from the doubled stock in the same manner that ordinary filSt6ll6F-bli1l1kS are cut from sheet metal of single thickness, the die, being of the configuration of the fastener, striking the flat side of the doubled stock, and the top of the die reaching to the top or folded edge of the doubled stock, so that when the fastener is struck from said stock the folded edge of the latter becomes the folded top or connecting portion of the former.

As a fastener to secure buttons to fabric, I

prefer the form shown in Fig. 2, wherein each half or side is provided with two penetrating prongs, c, and in which the folded edge a of the strip A constitutes the top or connecting por tion 2 of the fastener, whereby when said fastener is secured to fabric four prongs are pro vided to be clinched in the under side, substantially as shown in Fig. 4, and thereby provide great holding-power to resist the strains to which button-fasteners are subjected.

In Fig. 5 I have shown a form of fastener containing all the essential elements of my in vention as adapted for use a lacing hook or stud, while in Fig. 6 a glove fastener or button is shown.

NVhile I deem a fastener in which each side or half is provided with two penetrating prongs, so as to provide four prongs in all, to be the best form for general use, yet,without departing from the spirit of my invention,fasteners with two prongs, as illustrated in Fig. 6, may be made; or, if desired, the number of prongs may be increased to more than four.

The form or configuration of that portion of the fastener which appears above the fabric after having been secured thereto, generally termed the head, is not of the essence of my invention, since it may be varied to suit the purpose for which it is intended, the essential requisites of my said invention as found in the various forms of fasteners being the sides or halves substantially parallel or adjacent to each other, and provided with one or more penetrating prongs, and in which the folded edge of the double strip constitutes the top or connecting portion of said sides or halves.

1. A fastener for the purposes specified, consisting, essentially, of equal sides or halves and a folded top or connecting portion, each ofsaid sides having a penetrating prong or prongs, substantially as set forth.

2. A fastener consisting of halves having a I connecting-portion or top and folded against or next each other, each of said halves having a penetrating prong or prongs adjacent to the WVi'tnesses:
