TWO-PART SEPARAB LE BUTTON.

SPECIFICATION formingvpart of Letters Patent N 0. 608,410, dated August 2, 1898.

Application filed CUIJBI 30, 1897.

To all whom it may concern.-

Be itknown that LORMSBY L. MAHoN,a citzen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Two- Part Separable Buttons, of which the following is a specification.

' This invention relates to a two-part separable button which comprises a socket member and a stud member. .Buttons or fasteners of this class are used largely for gloves. The present invention has particular reference to the socket member only and may be used with any of the known constructions of elastic studs.

The object of the invention is to'provide a socket member composed of very few parts and which will be of cheap construction.

The device is illustrated in the accompanying drawings, in Which- Figure lis a sectionalview of the cap in one piece in readiness to be attached to the socket on the fabric. Fig. 2 is a View of the closed-end socket-eyelet. Fig. 3 is a sectional view of the socket member complete attached to the fabric, there being only two component pieces. Fig. 4: is a sectional view of the cap and a separate in closed ring secured together. Fig. 5 is a sectional view of the vimproved socket member complete, wherein three component pieces are. v

The letter A designates the socket-eyelet, having a closed end, which, before attachment to the cap, is rounded or peaked, as at b. This socket has a fiange c and aslightlycontracted entrance d. It Will be understood the interior of this closed-end eyelet is to con-V stitute the socket-chamber to receive a stud member of the button. A cap F covers the closed end of the eyelet and has an internal The top of the cap has a slightly-concaved interior surface at e. The metal continues from the top and forms an outer circular Wall g, then an inward-turned annular bearing-surface h, and ending in an internal sleeve t', projecting toward the said top of the cap. All these parts (see Figs. l and 3) are in one integral-pieceof sheet metal. In the manufacture of the cap there isan open` space bese'rial No. 656,983. m0 model.)

tween the top edge of the sleeve t' and the interior surface of the top, and over this top edge the upper part of the closed eyelet is bulged, as at j, thereby producing an engagement of the tWo parts. This is effected as follows: The closed end of the tubular eyelet is forced through a hole in the fabric 7c until its flange c comes in contact with the fabric on one side, the closed end projecting on the opposite side. The cap F then has its sleeve 'i slipped over the said tubular eyelet until the rounded or peaked closed end b contacts with the slightly-concaved interior of the cap.

As the rounded or peaked shape of the closed end, by yreason of its arched formation, is stronger than the part of the metal immediately at the base b of this arch, the effect of die-pressure noW brought to bear on the cap and eyelet will be first to bulge or expand the eyelet at the said base and then to flatten the arched formation, thereby simultaneously bringing the annular bearing-surface h in close contact with the fabric and producing the bulged part j, which projects over the top edge of the sleeve t' and locks the two pieces together on the fabric 7a. This preferred form produces a very rigid socket 1nember that is free of seams or joints.

Figs. a and 5 show a cap F and a ring inclosed in the cap. This ring is approximately U -shaped in cross-section. The internal rim t" serves as a sleeve and is shorter than the prisin g a cap having a slightly-concaved interior surface, an outer circular wall, and an internal sleeve projecting toward said concaved interior surface 5 and a socket-eyelet projecting into said internal sleeve and having a flange, c, a contracted entrance, d, and a flats IOO in combination with a soeket-eyeiet projecting into said internal sleeve and having a iiange, C, a contracted entrance, d, and a fiattened closed end which is bu] ged or expanded, as at, j, over the edge of the sleeve, as set forth.

In testimony whereof I affix my signature in the presence of two witnesses.
