sner-rasrnm Specification of Letters Patent.

Patented May 27,1919.

Application filed September '26, 1916. Serial at. 122,303.

' Be it known thatI, FLOYD H. OGDEN, a

citizen of-th'e United States, and resident of ,Roxbury, county of Suffolk, Commonfication, like characters on the drawings representing like parts in each of the several views.

This invention relates to snap fasteners especially adapted for use on garments,

- though having other and more general fields of usefulness, of a type composed of two relatively shallow cup members, one of which is formed to constitute a snap socket and the other to constitute a head or male member adapted to be pressed into said socket with a snap fit, both of said members being suitably perforated and adapted to be sewed on to a fabric or other sheet as by a power operated sewing machine. A prime object of the invention is to provide improved reliable means for effecting the snap and spring holding action between the two members of the fastener, this being preferably accomplished in the present instance by the employmentof a separate spring element applied to the head or male member of the fastener and projecting at intervals therethrough to engage the inturned edge of the socket member of the fastener. The distinctive features and obj ects of the invention will be better understood from the fol- I moved;

- Fig. 3 1s a central vertical section showing the two members of the fastener secured to pieces of fabric andinterengaged as in use;

Fig. 4: is a side elevation of the head member of the fastener;

Fig. 5 is a plan view of the socket mem- Fig. 6 is a side elevation of the socket member.

The socket member of my improved fas-- tener is indicated at 10 as of shallow cup formwith a flat bottom portion and an upright flange portion 11, the bottom portion being suitably perforated as seen at 12 to permit stitchingato be passed therethrough by a power operated sewing machine. The top portion of the flange 11 is crimped inwardas indicated at 13 to engage the periphery of the head member and cooperate therewith for the snap and spring pressing interengagement between said members. While the preferred form of this socket member is substantially as shown, its form may be varied somewhat and still be adapted for cooperation with the improved form of head member as-now to be described for coaction therewith. The head or male member of the fastener as indicated at 14: is also of shallow cup form somewhat smaller than the socket member with a fiat bottom also 7 .provided with stitching holes 15. for the stitching S, in like manner as the holes 12. This head member is formed with a lateral flange 16 efitending from the bottom thereof, this flange being suitably curved or convexed externally for interfitting with the inturned edge 13 of the socket. In accordance with my invention the dimension of this convexed flange 16 is such as to fit'as closely as may be into the passage formed by the inturned edge 13, though by reason of the spring provision now to be described, the necessity for a particularly accurate or close fit between these members is obviated. The flange 16 of the head member has longitudinally extending slots 17 formed therethrough at spaced apart points, three such slots being shown, and through these project outward bulges or humps 18 formed in a stout spring wire or rod 19 formed and bent to fit within the concave inner side of the flange 16 and with its ends spaced apart as seen at 20 to permit the requisite range of spring action. These humps 18 on the spring 19 therefore project through the.

is adapted to press said humps inward as thefastener members are assembled, to permit the head flange 16 seats on the bottom of the socket 10, the spring humps 18 still engage with some little pressure the edge 13, thus holding the members with a constant resilient pressure against all looseness or play therebetween. It is to be noted that the spring humps 18 will interengage with the crimped-in edge 13 to produce a pronounced snap action between the head and socket members and that these humps being spaced apart as shown will find secure and reliable seats within the crimped-in edge 13, even though such edge and the socket member, or the head member itself, may be somewhat inaccurate or deviating from a true circular shape. I do not desire to be limited to precise structural details as herein exhibited, and desire the present illustration to be considered as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description, to indicate the scope of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A snap fastener, comprising a socket member formed as a relatively shallow, generally circular cup with a flange having an inturned edge, and a head member to interfit therewith consisting in a relatively shallow cup having a convexed peripheral flange formed with spaced apart lengthwise slots, and a spring member formed with humps rounded in cross section arranged to project through said slots for engagement with the inturned edge of the socket memher and adapted to be pressed in thereby and then snap back into holding engagement therewith.

2. A snap fastener, comprising a socket member formed as a shallow cup having an inturned head holding flange, and a head member to interfit therewith also consisting in a shallow cup having a peripheral flange with a convexed outer face formed with spaced apart lengthwise slots, and a curved spring wire formed with rounded humps adapted to be seated within the flange of said head member with the humps thereon consisting in a relatively shallow cup having a lateral flange at its periphery presenting a convex outer face, said flange formed with spaced apart. lengthwise slots, and a spring member curved to fit within said flange and having humps formed thereon to extend through said slots to engage with-a socket member and adapted to be pressed in thereby and then snap back into holding engagement therewith.

4. A snap fastener, comprising a socket member formed as a relatively shallow, generally circular cup.- having a head retaining flange formed with a crimped-in edge, and a head member to interflt therewith consisting in a generally circular relatively shallow cup having a lateral flange to engage with said socket member, said flange having a lengthwise slot therein, and a spring wire fitted within said flan e and having a hump projecting less than lialf its cross section through said slot to engage with the grimped-in flange edge of said socket mem- 5. A head member for a snap fastener, consisting in a relatively shallow cup having a lateral flange at its periphery presenting a convexed outer face, said flange formed with a slot therethrough, and a member circular in cross section presenting a resilient projection extending through saidslot less than half its cross section to engage With a socket member in which said head member is fitted. 4

6. A head member for a snap fastener, having a lateral flange at its periphery presenting a convexed outer face and formed with spaced apart lengthwise slots, and a resilient projection extending through each slot to interengage with and be pressed in by a socket member to which said head member is fitted. I

In testimony whereof, I have name to this specification.
