SOCKET MEMBER.

SPECIFICATION forming part of Letters Patent N 0. 769,778, dated September 13, 1904.

Application filed February 9, 1901. Serial No. 46,648.

To all whom, it may concern:

Be it known that I, JOHN D. STIROKLER, a citizen of the United States. and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Socket Members, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,forming a part of this speci- IO fication, in explaining its nature.

The invention relates to the herein-described improvement in single-piece socket members of ball-and-socket fasteners.

It comprises a hollow structure having be- 5 fore it is set to material a continuous top which corresponds to the part of a fastener known as a cap and which extends over the socket-entrance and over the flange to cover and conceal both, a flange which bears against a surface of the material to which the member is set, and a tubular extension from said flange having longitudinal slits or openings in it, not, however, extending through the lower edge or into the flange unless desired, and 5 which tubular extension is adapted to be passed through a hole in material to which the socket member is secured and in the act of setting or securing the member to then be formed to provide a socket-entrance substantially upon 3 a line with the surface of the material opposite that upon which the preformed flange bears, and a continuous inner fastening-flange extending from the socket-entrance upon the inner surface of the said material. Referring to the drawings, Figure 1 is a View in elevation of a socket-piece. Fig. 2 is a view in vertical section of a socket-piece and of material, the socket-piece beingassembled with the material, but not being set. Fig. 3 4 is a view in section of the set socket-piece or socket member and the material. Fig. A is a View in plan, inverted, of the socket member and material. Figs. 5, 6, and 7 represent a modified form of socket-piece and socket member to which reference will hereinafter be made.

Referring to the drawings, a represents the top upper surface or cap of the member. It

is of any desired configuration, is preferably continuous, and is not changed In shape mate- 5 .rially, if at all, in the act of setting. It covers the flange b and the socket-cavity 0. The flange Z; is integral with the cap a and and has a tubular extension (Z, provided with the longitudinal openings 0, which may be confined to a portion of the tubular extension, as represented in Figs. 1 and 2, or which may be arranged as shown in Figs. 5 and 6. The lower edge f of the tubular extension is continuous and is scalloped, as represented. The tubular extension preferably is offset, as represented in the figures, and the shoulder thus formed in the set socket-piece or socket member forms the edge about the socket-entrance and an enlargement within said edge. The oifset is oh- 5 tained by making the upper part ofthe tubular extension larger in diameter than the lower part. An unset socket member of this structure lends itself readily to a transformation in the act of setting to material, whereby a socket- 7 O entrance 9 is formed, the cavity 0 above or within the socket-entrance established, and an inner fastening-fl ange it, continuous at its outer edge, obtained. Such a sprocket member may be used with a resilient ball member or not, as desired. If the ballmember is not resilient, it will be desirable, though not necessary, to use longer openings 0 in the tubular extension than would otherwise be used. By making the lower edge of the tubular extension scalloped 30 provision for the change in the disposition of the metal from the tubular form to the flat form of a continuous flange is secured. By extending the slits or openings 6 to or into the scallops they may be made longer than if they 5 are extended radially toward the points between the scallops, and hence will'serve more surely the purpose in forming the flange per-- tion of the set device of allowing the material of this portion of the device to adjust itself 9 according to the conditions of its use.

The structure shown in Figs. 3 and 4 is adapted to be used with a yielding ball member and the structure of Figs. 6 and 7 with an unyielding ball member.

Having thus fully described my invention,

I claim and desire to secure by Letters Patent of the United States 1. A socket-piece of a ball-and-socket fastener made from one piece of metal and having a preformed cap, a folded flange, and a cylindrical extension from the inner end of the flange of two diameters, the section of said cylindrical extension nearest the flange being of a larger diameter than the outer end of said cylinder and forming with said outer end a shoulder at the socket-entrance, the said outer end section being of a length to form when upset an inner fastening-flange, and also having slits which may extend into the shoulder and which do not extend through the end of said cylindrical section, whereby the smaller cylindrical section may be folded outwardly to form a fastening-flange having a continuous edge and a socket-entrance immediately below said shoulder.

2. A socket-piece of a ball-and-socket fastener made from a single piece of metal having a cap, a flange, a tubular extension from the flange having a continuous scalloped edge and slits in said tubular extension extending to or into said scallops, whereby a portionof said cylindrical extension may be folded? from a cylindrical form to the form of a folded fastening-flange at a right angle to the cylindrical section and with a continuous outer edge, said slits allowing the material of said flange to adjust itself during the process of folding to allow. said flange to lie substantially flat against the fabric.

3. A socket member of a ball-and-socket fastener made of a single piece of metal and having a cap, an upper retaining-flange, a tubular body abruptly contracted at its lower end or throat, and a radially-slitted, lower retaining-flange having a continuous outer edge, the upper retaining-flange being continued at its outer circumference into the cap and at its inner circumference into the tubular body, and the tubular body being continued at the throat into the lower retaining flange.
