BUTTON.

SPECIFICATION forming part of Letters Patent No. 424,733, dated April 1, 1890.

Application filed January 27, 1890. Serial No. 338,184. (No model.)

T0 all whom it may concern:

Be it known that I, JOSEPH R. SMITH, of Vaterbury, in the county of New Haven and State of Connecticut, have invented anew Improvement in Buttons; and I do hereby declare the following, when taken in connection specification, and represent, in

Figure l, a vertical section of the button detached; Fig. 2, the shank of the button as prepared for attachment; Fig. 3, a vertical section of the fastener detached and Without the cap; Fig. 4, the same section With the cap; Fig. 5,avertical section representing the button as applied to a garment; Fig. 6, the instrument by Which the fastener may be introduced; Fig. 7, the button as made from a single disk.

This invention relates to an improvement in the construction of buttons and fastenings therefor, whereby the button is readily secured to the garment, the object being a simple construction, which enables the button to be quickly and easily applied to the garment, and When once attached is substantially inseparable from the garment; and it consists in the construction as hereinafter described, and particularly recited in the claim.

A represents the front or face of the button, which is made from metal; B, a metal disk arranged on the back of the face, and around which the edge of the face is closed so as to secure the disk B firmly in place. The disk B forms, practically, the back of the button. Before uniting the back B to the face a shank C is secured to the back, Which Will raise it vfrom the surface to Which the button is to be attached. This shank is a metal tube constructed with an annular shoulder ce at one end, produced by a reduction in the diameter of the tube, the portion above the shoulder being adapted to pass through a corresponding opening in the back B, and so that the end may be closed down thereon, 'as seen in Fig. l, to firmly secure the shank thereto. The opposite end of the shank is constructed With an internal annular shoulder l) by an enlargement of the diameter of the shank at that end. Into this tubular shank an eyelet D is set, its iiange resting on the shoulder b and the surrounding metal of the shank closed down thereon, so as to firmly secure the eyelet in a central position in the shank, as seen in Fig. 1. The length of the eyelet is such as to leave a free space around its inner end. This completes the button.

The fastening is composed of a tube E (see Fig. 3) of an external diameter substantially the same as the internal diameter of the eyelet B. This tube is constructed With a flange CZ around the head end, and from the other end one or more slits e are cut, so as to split the tube from that end toward the head. At the split end the edge is turned outward to form a slightly-projecting angef. The length of the tube between the flanges d and f is somewhat greater than the length of the eyelet D, and preferably over the head end a cap F is applied, its edge closed around the flange and so as to form a close head for the fastening device. The slitting of the tube E gives to it at the split end a considerable degree of elasticity, so that it maybe readily contracted, and by the reaction under its own elasticity resume its normal position when the force which contracts it is removed. pletes the fastener. To attach the button, the button is set upon the side of the garment, or Whatever it may be to which it is to be applied., and the split end of the fastener is introduced through a corresponding hole in the garment, force being applied to drive the fastener into the button. The funnel shape of the eyelet D Will cause the tube E to contract until the flange f shall have arrived at a position above the upper end of the eyelet, as seen in Fig. 5. Then the react-ion of the tube E causes its expansion, the flange f passing over the end of the eyelet, and so as to engage there- With, which prevents the accidental Withdrawal of the fastener from the button.

The cap F may be omitted from the fastener 5 but I prefer to employthe cap, as it covers an opening, which would otherwise exist, into the tube.

Asaconvenience to introduce the fastener, apointed instrument such as seen in Fig. 6 may be employed, it being constructed of a diameter at its base, corresponding to the di- This com- ICO ameter of the flange f of the fastener, the base having a shank to set Within the tube E, as seen in Fig'. G, and so that by applying the point upon the reverse side of the garment, where the button is to be attached, and forcing this instrument through the garment, the fastener will follow the instrument. Then when the instrument is removed, the button is forced onto the fastener, this being a common and Well-known device for attaching buttons of this class.

It will bev understood that the face of the button may be omitted, as in case Where the button is made from a single disk, as B, Fig. 7.

I claim- A button composed of a disk havinga tubular shank C, centrally attached thereto, combined with an eyelet set Within said shank of a length less than the internal length of the shank, the liange of the eyelet closed Within the outer end of the shank, and a fastener composed of a split tube E of a diameter corresponding substantially to the internal diameter of said eyelet and constructed With a flange d at one end, the tube split from the opposite end, and the said opposite end constructed with an annular outwardly-projecting flange f, the length of the tube between the anges cl and f somewhat greater than the length of the said eyelet, said tube adapted to enter said eyelet, and the said flange f to engage over the inner end of the said eyelet, substantially as described.
