ans an WILLIAM H. REID, OF BROOKLYN, NEW YORK SEPARABLE FASTENEB.

Specification of Letters Patent.

Patented May 9,1916.

Application filed March 4, 1916. Serial No. 82,014.

To all whom it may concern Be it known that 1, WILLIAM H. REID, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York. have invented certain new and useful Improvements in Separable Fasteners, of which the following is reason of a special form of a tongue member, that is formed by merely providing a special configuration of the edges of the blank, and which tongue is given the special bending operation.

A further object of the invention is to provide such a construction in which the socket member will be integral with the tongue, so that the device comprises simply two members, the spring member and the body member.

In the accompanying drawing showing one embodiment of my invention, Figure 1 is a plan view of the device. Fig.2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3 is a vertical section on the line 33 of Fig. 1; Fig. 4: shows a head member that cooperates with the socket member'of Fig. 1. Fig. 5 is a plan view of the spring member. Fig. 6 shows the blank as cut out. Fig. 7 is an edge view of the blank. Fig. 8 shows the blank with the head portion of the tongue pressed into final shape. Fig. 9 is a side elevation of the blank as shown in Fig. 8. Fig. 10 shows a blank of Fig. 9

with the tongue bent over on to the base;

and Fig. ll is a section through the form of button as at present in use.

Heretofore fasteners of this character have been provided in which the base 12 has a head 13 formed integral therewith by a simple die operation of expanding the center of the blank to form a substantially semi-spherical head or cap, as shown m Fig. 11. This cap has been provided with openings or slots 1% and 15 on two opposite sides, adapted to receive a spring similar to the spring 16 shown in Fig. 5. This spring had its

end portions

17 and 18 projecting into the slots 14. ans. 15, to engage the head on the head member, such as the head 19 on the member 20, as shown m Fig.

1 But it has been found very difficult in practies to produce the openings 11 and15 in the members, by reason of their being of a very small size. T o-overcome the necessity of cutting or punching such slots, I provide a button which has a base member 21, and a cap member 22 in the form of a band having an enlargement at its middleportion. This band is preferably made integral with the base member, as shown, and is provided in the blank with a, circular enlargement23 connected by a strip 24 with the base 21, and having astrip 25 at the free end. The d1sk port1on '23 is engaged by proper dies to give it a cap shape 26, preferably'semispherical and this cap has upright portions 1 21 and 28, that extendvertically downward from the cap, and are formed by'bending upward the portions of the

strips

21 and 25 ad acent the cap, as indicated in Fig. 9. By th s means it will be seen that the cap will have its opposite sidesbetween the upright portions 27 and 28 free, and which are off-set from the plane of the

strip portions

21 and 25. The cap niemberis next bent portions 2+1 and 25 of the band will engage the base between the spring ends. This form of a member usually is the side edges bent over or beaded as at 30. to engage the outer portion of the spring 16 and-hold it I in position. The strip portion 21 is preferably bent over on top of this spring, as indicated in Figs. 2 and 10. The extremity of the cap member or strip '25, will also be engaged by the bead 30 that will serve to retain the cap member in position on the base 21. It will thus be seen the

spring portions

17 and 18 will lie beneath the portions of the cap member, that will overhang them and prevent their being forced upward by the head 19. These spring members will project across opposite portions of the bore 29. as indicated in Fig. l, andwhen the head enters the socket, the spring members will grip thehead and retain the two members together in locked position. It will be further seen that the spring mem bers engage the side edges ofthe upright portions 27 and 28, that limit the inward movement of the spring members, as clearly shown in Figs. 1 and 4..

It will thus be seen that l have provided a construction in which there is a head mem- I be'r'havingundercut portions on two opposite sides to receive the spring, members and hold them properlyshaped to engage the head member; and that the spring members are prevented'from being forced up- Ward by the head, because of the overhanging of the cap members. But such-construction is provided without any'openings being formed in the cap member at any stage in the manufacture, and is a result of the con- :figuration of the margins of the blank and of very simple bending operations.

Having thus described my invention, what I claim is 1. A resilient socket member for a head and socket fastener, comprising a base member having acentral bore to admit the head, a member extending across the base and having two upright portions adjacent the bore margins connected at the top by a portion whose 'the said upright portions,

dome shaped portion whose opposite sides project over said bore margins between said upright portions, and a wire spring on the base having portions extending across the margins of the said bore in the base adapted to engage the head, which said spring portions lie beneath the said dome portions and engage the said upright portions.

2. A resilient socket member for a head and socket fastener, comprising a base member having a central bore to admit the head, a member extending across the base and having-two upright portions adjacent the bore connected at the top by a dome-shaped OPDOSltG sides project over said bore margins between said upright portions, and a wire spring on the base having portions extending across the margins of the said bore in the base adapted to engage the head, which said spring portions lie beneath the said dome portions and engage the said base member havlng its margins beaded to inclose a part of the spring member and to secure the said dome member at its ends to the base.

3. A resilient socket member fora head and socket fastener, comprising a base. member having a central bore to admit the head, an integral extension of the base member bent over to lie against the base and having two upright portions adjacent the'bore margins connected at the top by a dome-shaped portion whose opposite si es overhang the bore margins between said upright portion,-

and a wire spring on the base having portions extending across the margins of the said bore in the base adapted to engage the ed at the top by a dome portionwhose opposite sides overhang the bore margins between said v upright portions, and a wire spring on the base having portions extending across'the margins of the said bore in the base adapted to engage the head when inserted, which said spring portionslie beneath the said dome portion and engage the said upright portions of the said extension, the said base member having its margins beaded to inolose a part of the spring memberv and .to secure the said extension at its ends .to the base.

5. A resilient socket member for a head and socket fastener, comprising a base member having a central bore to admit the head, a non-apertured cap member extending across the base and provided with a dome shaped portion whose opposite side edges overhang the bore margins, and a wire spring on the basehavingportions extend ing across the margins of the said bore in the base adapted to engage the head member when inserted, which said spring portions lie beneath the said cap projections,

and which normally engage the margins of said cap member to hold the spring in said head-engaging position.
