BUTTON-FASTENER.

SPECIFICATION forming part of Letters f Patent No. 294,411, dated March 4, 1884.

Application filed December 17, 1883. r(No model.) i

.To @ZZ whom, it may concern:

Be it known that I, FRANKLIN A. SMITH, Jr., a citizen of the .United States, and a resident of Providence. county of Providence, and State of Rhodev Island, have invented an Improvement in Button-Fasteners, of which the following description, in connection with the accompanying drawings, is a specification,

like letters on the drawings representing like i 1o parts,

My invention belongs to that class of sheetmetal button-fasteners which are adapted to 'hold buttons to shoes or other articles Awithout the aid of a setting-instrument. Button-fasteners of the class mentioned are usually so coustructed as to involve two bends in the metal blank to adapt it for use, or which necessitates one continuous bend in the tongue of theblank to form said tongue into a curvilinear or seg- 2o mental loop or hook, so as to bring the end or point of the tongue or formed loop or hook adjacent to and opposite one side of the head bar or base. Button-fasteners involving two bends intheir formation must be formed of com- 2 5 paratively thin, soft, and tender metal, and

are much weakened by the sharp bends therein, while fasteners which are formed by giving a continuous bend to the tongue of the blank to form the curvilinear or'segmental loop or hook are difficult of manufacture, and

when so formed the end of the loop or hook is so disposed with relationv to the other parts of -the fastener that when it is endeavored to engage the hook with the yeye of a shank-button it is found that thecurve or bulge of said loop or hook engages the material ofthe shoe or other article before, the end or point of the loop or hook can enter the shank-eye, thereby rendering the engagement of the fastener 44o with a button a diflicult matter.

- My invention. has for its object the formation of a button-fastener of the class designated V To thesel ends my invention consists of a sheet-metal button-fastener having, essentially, abase and hook integral therewith, with the hook bent upon itself, and with its free end-or that portion below the curvature or bend opposite to and substantially parallel with one side of the base, substantially as hereinafter described, and particularly pointed out in the claims.

Figure 1 is an elevation, and shows my im 6o proved button-fastener, enlarged, as holding a button to a piece of leather or other article. Fig. 2 is a .plan of the blank from which my fastener is formed. Fig. 3 is au end viewof my improved button-fastener. Fig. 4 is a rear 65 View, and Fig. 5 is a front View, thereof.

My fastener is formed from the sheet-metal blank shown inFig. 2, and consists of abase,

a, and hook b.- The khook projects from the cut edge c of the base a, and is curved or 7o bent upon itself, as at d, with its free end or that portion below the curvature or bend opposite to and substantially parallel with one Y side of the base c, as shown in the drawings. By this disposition of parts the hook -may be 75 readily engaged with the shank-eye of a button, and be' easily housed in the hole in the v leatheror .other article, so as to bring the shank-eye of said button substantially above and atthe outer surface of the leather. The 8O point or extremity of the hook b is As0 disposed as to be substantially in the same plane with or slightly below the bottomline ofthe base a, the purpose of which is to prevent the free end of the hook b from being pulled through 8 5 the hole in the leather and onto the outer surface thereof when stra-in is applied to the button and the hole becomes enlarged by wear. The strain or pull on the button being substantially at right `angles to the base or some- 9o what inline with the leather or other material, the said strain causes the end of the hook b to press against the under side of the mate# rial at one side of the hole therein, while the base presses against the material at'the oppo- 95 and were the point of the hook not carried to or slightly below the bottom line of said base it Would soon be pulled out of the hole and onto the outer surface of the material upon the enlargementby wear of the hole in said material.

Myiinproved hook is cheap and of easy inanufaeture, and involves but one silnple bend, given thereto by the die or former. As stated, the hook can be quickly and easily inserted into the eye of a shank-button.

Then it is desired to apply a button and fastener to a fabric or shoe, the shank of t-he button is pushed into a previously-made oriiiee in the fabric or leather of the shoe, so that said shank will project from the underside of the material, when the point or extremity of the hook is passed into the shanlceye until the bend of the hook engages the said shank-eye. whereupon a pull is given to the button to cause the hook to be drawn up into the oriiiee, substantially as indicated in Fig. 1.

l. A sheetmetal button-fastener consisting of the base and the hook integral therewith,

the said hook projecting from the eut edge c of the base, and having the semieircular bend d and straight free end below. the said bend d, the said straight free end being substantially parallel with the post of the hook below the said curve and with the base, the point or eX- treniity of the hook passing beyond the upper eut edge, c, of the base, substantially as shown and described, and for the purpose set forth.

2. The hereindescribed one-piece sheetmetal button-fastener, consisting, essentially, of the base a and hook b, the said hook projecting from the out edge c of the base and bent upon itself, with its free end opposite to and substantially parallel with one side of the base a, and its point or extremity slightly below 'the bottom line of said base a, all as shown and described, and for the purposes set forth.

In testimony Whereoi'l have signed my name to this specification in the presence of two subseribing witnesses. FRANKLIN A. SMITH, JR.
