FASTENER.

SELECIFICATION forming part of Letters Patent No. 667,874, dated February 12, 1901. Application led May 5, 1900. Serial No. 15,641. (No mocleL To f/,Z whom z'f may concern:

Be it known that l, ALBERT F. FISHER, a citizen of the United States, residingat Dedham, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Fasteners, of which the following is a specification.

'lhe object of this invention is to produce a strong, convenient, and durable snap-fastener for boots and shoes, gloves, and clothing and to produce a fastener which shall not become accidentally unfastened by the pressure or strain brought to bear thereon (tending to unf-asten the same) by the hand where the fastener is applied to a glove or the foot when said fastener is applied to a D001).

The invention consists of afastener in two parts, a sind and a cap, said stud consisting of a plate having' a bifnrcated standard thereon adapted to engage a rib extending diagonally across the interior of a hollow hemispherical cap.

The invention further consists in means whereby said cap is prevented from moving upon said stud lengthwise of said rib.

The invention still further consists of the combination and arrangement of parts set Vforth in the following specification, and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is an enlarged side elevation, partly in section, of my improved fastener, showing the same applied to a portion of the upper of a boot or shoe, said upper being shown in section. Fig. 2 is a sectional elevation of the same, taken on line 2 2,`Fig. 1, looking toward the left in said figure. Fig. 3 is a sectional elevation similar to Fig. 2, showing the cap in section and the stud in elevation. Fig. L1 is a perspective view of the fastener-cap shown in Figs. 1, 2, and 3, having ears by which said rap is attached to the material in lieu of the flange shown on the cap in said figures. Fig. 5 is a perspective view of the fastener-stud. Fig. o' is a plan View of the fastener-cap. Fig. 7 is a perspective view of a portion of the u pper of a boot or shoe with my improved fasteners attached thereto.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, l0 is the fastener-cap, and

11 the fastener-stud. Said fastener-stud consists of a flat plate 12, having prongs 13, by which said stud is fastened to the stock 14 of the upper of a boot or shoe.

15 15 are two standards formed upon the plate l2, each consisting of a shank portion 16 and a curved rounded head portion 17. Each of the shank portions lo is provided with a notch 13 to engage a projection upon the fastener-cap, as hereinafter described.

The fastener-cap 10 is formed, preferably, of sheet metal, and consists of a hollow hemisphere having a flange 10 thereon, as shown in Figs. 1, 2, and 3, or ears 20, as shown in Figs. 4 and 6, said flange or ears being perforated to enable said cap to be attached to the stock 14 by thread 21. The fastener-cap has a depressed central portion or rib 22, which extends diagonally across said cap and is rounded out at the lower portion thereof to engage the standards 15 15. A projection 23, formed upon the cap l0, engages the notches 18 upon the standards 15.

The operation of the device is as follows: The fastener-cap is pressed down upon the stud 11, the depressed or rib portion of said cap entering the space 24 between the standards 15. Said standards spring apart and allow the enlarged lower portion 25 of the fastenercap to pass between said standards and to enter the enlarged port-ion of the space 24E between said standards, whereupon the stand ards spring back to their normal position and prevent the cap from moving upwardly. When the cap has been pressed upon the stud, hereinbefore described, the projection 23 enters the notches 1Sin the standards 15 and the rounded head portions ofrsaid standards abut against the inner face of the heinispherical cap. When the cap is pressed onto the stud, as shown in Figs. 1, 2, and 3, said cap is prevented from becoming accidentally detached therefrom by any movement or strain brought to bear thereon by the foot inclosed in the shoe, by the springstandards which incl'ose the rib 22, and by the projection 23, .which is engaged by the notches 1S. It is evident that the cap cannot move lengthwise of the rib 22, as it is prevented from moving to the right, Fig. l, by said projection 23, which bears against the standards 15, and from moving to the left in IOO said figure by the heads 17 of said standards, which bear against the inner face of the cap.

The only manner in which the cap can be detached from the stud is by lifting up the stock attached to the cap at the right-hand side of said cap, Fig. 1, until said cap has been raised to a sufficient extent to allow the projection 23 to be disengaged from the notches 1S, when the standards 15, spread-ing apart, allow the rib 22 to pass out from between them, and the cap will then become disengaged from the stud.

It is evident that the cap may be made from a solid piece of metal and the outer surface thereof be perfectly smooth with no depression therein, the rib 22 being formed solid thereon or fastened thereto, without departing from the spirit of my invention. It is also evident that the two standards 15 15 are of said cap and adapted to engage each of said standards; and notches in said standards arranged to engage a projection upon said cap.

2. In a fastener, ahollow hemispherical fastener-cap, a rib extending diagonally across said cap; in combination with a pair of standards upon a fastener-stud, said standards being integral with a plate and having a shank portion and an enlarged head portion, said rib arranged to engage said standards; and

r a projection upon the interior of said fastener-cap arranged to engage notches in said standards.

3. A fastener in two parts; a stud consisting of a plate and two standards integral therewith, each of said standards having a shank portion and an enlarged head portion; and a hollow ltemispherical cap, a rib extending diagonally across said cap and ar- .ranged toengage said standards; notches in said standards and a projection upon said cap arranged to engage said notches.

1n testimony whereofl I have hereunto set my hand in presence of two subscribing wit messes.

ALBERT F. FISHER.
