JAMES F. THAYER, OF PROVIDENCE, RHODE ISLAND.

BUTTON-FASTENER.

SPECIFICATION" forming part of-Letters Patent No. 277,082, dated May 8, 1883.

Application filed January 8, 1883.

To all whom it may concern:

Be it known that I, JAMES F. THAYER, a citizen of the United States, residing at Providence, in the county of Providence and State ofRhode Island, have invented certain new and usefullmprovernents in Button-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to an improved fastening for attaching buttons to shoes, 850.; and it consists of a fastener formed from grooved or channel wire bent to astaple form, the loop thereof terminating in two depending prongs or legs, the ends being beveled in opposite directions and adapted to be inserted through, the fabric and clinched thereunder bya suit able setting-instrument.

In the accompanying drawings, made enlarged, Figure 1 represents a perspective view of my improved fastener as madefrom grooved wire. Fig. 2 represents the same in partial section when attached to the fabric with button and clinched thereunder. Fig. 3 representsvarious or modified formsof grooved wire which may be used.

Aiu the drawings representsastaple-formed fastener, provided with an eye, a, and two downwardly-projecting prongs, a, the latter beveled off, thereby forming two sharpened points or spurs on each of said prongs, as

shown at a the Whole made from grooved wire, as shown.

I am aware that half-round and other forms of solid wire have been employed for button- (No model.)

rics with my grooved wire fastener I pass.

one prong thereof through the eye b of the button B, when the fastener and button are both placed in the jaw of a suitable setting-instrument, after which the latter is placed in position relatively to the fabric, the instrument being then made to pass or force the prongs a through the fabric or material and clinching thereunder, the ends a thereof being flattened during the operation, said ends thereby presenting a much broader surface to the material for holding, the points or spurs a also being susceptible ot'repenetratiug the fabric,

thereby holding the fastener in position.

Having thus described my invention, what I I claim as new, and desire to secure, is-

The improved button-fastener A, herein described, consisting of the loop a and prongs a/ a, the latter beveled at a the Whole being concave-convex in cross-section throughout its length, and adapted for use substantially as shown and set forth.

In testimony whereof I have at'fixcd my signature in presence of two witnesses.

JAMES F. THAYER.
