FASTENER.

SPECIFICATION forming part of Letters Patent N o. 574,009, dated December 29, 1896. Application filed January 27, 1896. Serial No. 577,063. (No model.)

T cir/ZZ whom t muy concern:

Be it known that I, ANTHONY B. SILvEBs- TON, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented an Improvement in Fasteners, of

which the following is a specification.

My invention relates chiefly to improve- A ments in button-fastenersof the class now commonly used as glove-fasteners and in 1o which a socket attached to one piece or portion of material receives a stud attached to another piece or portion; and the main objects of my improvements are, irst, to provide a button of the class referred to in which a I5 spring-socket will engage and hold the head of a stud; second, to provide a fastening which will be suitable for use as a shoe-button as well as a fastener for gloves and other like purposes; third, to provide a button 2o which,whi1e easily unfastened when an attempt is made to pull the stud straight out of the socket, will strongly resist the strain y brought upon it when the pieces or portions of material to which the stud and socket are respectively attached are pulled sidewise in opposite directions; fourth, to provide a button which will be simpler, cheaper, stronger, and more durable than any fastener of the same general class heretofore devised, and,

3o fifth, to provide means for detachably fastening bows or ornamental strips of fabric to a garment. I attain these objects by mechanism whose preferred form is illustrated in the accompanyingdrawings, in which,

5 3 applied to a glove, shown unfastened. Fig. 2 is a cross-section, on an enlarged scale, of the outer portion of the fastening on line 2 2, Fig. 1. Fig. 3 is asimilar'view at right an- 4o gles to Fig. 2 on line 3 3, Fig. 1, with the bow shown in Figs. l and 2 omitted. Fig. 4 is a cross-section, on an enlarged scale', .through the stud on line 4 4., Fig. 1. Fig. 5 is a combination of4 Figs. 2 and 4. with the bow omitted, showing the stud and socket in position to be fastened by pressing the socket down over the head of the stud. Fig. is a similar view showing the parts fastened together; and Fig. 7 is a view similar to Fig. 6, show- Figure l is a front view of my improvement" ing the button-fastener with the means for 5o retaining a bow or strip of fabric omitted.

Similar letters refer to similar parts throughout the several views.

A represents the socket portion ofthe fastening. It is preferably made of an elastic 5 5 sheet metal, such as sheet-brass, and preferably so stamped or otherwise formed into shape as to produce an annular depression or groove et, running around its outside between its mouth and its opposite end and preferably 6o substantiallyparallelv with the lip a of the socket, and onits inner side a corresponding inwardly-projecting annular shoulder or ring c2.

The shoulderor ring a2 is divided by means 65 of a series of perforations a3 into a series of elastic segments a4, which, however, do not necessarily extend clear across the ring.. The forms of the perforations and segments shown are not essential, though desirable. The seg- 7o ments a are curved or bowed between thread endsor points of attachment to the edges of the ring a2 or the body of the socket-piece A, their convex faces being turned inward. Their outer ends are preferably joined by the 7 5 lip or mouth a of the socket and their opposite ends by the opposite portion a6. The perforations c3 are preferably in the formof slots running at substantially right angles to the central longitudinal line a of the shoul- 8o der or ring a2, as shown. It is not essential that they'shall extend clear across said ring. The top a7 of the socket-piece A is shown closed, but that, though desirable, -is not essential.

To the outer portion of my improved fastener a clasp or -other fastening is preferably attached where the device is used at a point where it is desirable to place a bow or strip of ribbon. lor other fabric as an ornament. 9o The special form of this fastener is not essential. It may be made in the form of a ring B, hinged to .the outer portion of the fastener on one side and fastened opposite the hinge by means of a spring-catch.

drawings this portion ofthe improvement is shown attached to the part A, the hinge being letteredb and the two portions of the In the v catch b and b2, respectively. As will be observed, the hinge and catch are of common and Well-known forms.

C, Figs. l and 2, represents a bow of ribbon held in place by the ring B.

The socket-piece A is preferably attached to the material d8, in connection with which it is used, by inserting it in a hole in such material and preventing Vits escape by causing the edges of the material to enter the annular groove d and be clasped between the lip a and the top c7, thus substantially riveting the part A in place. Then the part A is thus attached, the perforations through it are preferably hidden by the material to which it is fastened, except when the inside of the socket is examined.

D, Figs. l, 4, 5, 6, and 7, represents a stud adapted to enterand be engaged by the socket A. Its head cl is slightly larger than the inside of the shoulder or ring d2 of the socket, and in order to pass such ring it has to bend the latters segments outward, and thus slightly enlarge its inside diameter. Below the head d the diameter of the stud should be smaller than that of the head at its widest part, substantially as shown at d', so as to allow the segments of the ring a2 to spring inward when the head. CZ of the stud passes them. It is immaterial whether the diameter of the inner end d2 of the stud be widened so as to be approximately the same as that of the head, as shown, or not, as will be obvious. As shown, the seat d in the stud for the ring e2 curves outward toward the outer end, and this form of seat is preferred, as it enables the stud to escape from the socket more readily than would otherwise be possible without preventing the socket from holding the stud as strongly as is necessary. The stud may be made in the shape shown and fastened in position by means of a rivet cl3, but, as will be obvious, thatspecial shape and method of fastening are not essential.

It is easy to regulate the force required to fasten and unfasten my button-fastener by making the diameter of the head of the stud larger or smaller in proportion to the inner diameter of the socket-ring. lVhere considerable force is necessary to expand the ring far enough to admit the head. of the stud, it is almost impossible to disengage it by `pulling the ypieces of material to which the stud and socket are respectively attached in opposite directions sidewise. The elastic strength of the ring a2 may also be varied in ways which will be obvious.

My improved fastener is not only strong, simple, and durable, but may be manufactured very cheaply.

yI claiml. In a fastener-socket, an annular concavity on the outside and a corresponding annular convex portion on the inside; a series of perforations dividing said concave-convex portion into inwardly curved elastic segments, an annular unbroken outer part joining the outer ends of the segments together and an annular unbroken inner part joining the inner ends of said segments together substantially as described.

2.
