. i My invention aims to provide improvements infasteners and fastener installations.
In the drawings which illustrate a preferred embodiment of myinvention2 Figure l is an elevation view of a preferred form of fastener installation;
Fig. 2 is an enlarged section taken on the Fig.`31is a side elevation ofa socket member prior to attachmentto a support; and
Fig. 4 is a plan view of the socket member shown in Fig. 3.
1 Referring to the embodiment of my invention selected for illustration by the drawings, I haveshown a snap fastener socket secured to a flexible carrying medium by a novel, eflicient and durable construction and arrangement of elements." It should be understood that any type of snap fastener element, button or like member may be attached in the same manner and, therefore, that my inventionV is not limited to the socket structure shown vand hereinafter described.
The socket illustrated has a one-piece casing 1 pressed from sheet metal and having astrid-receiving aperture 2 intersected by an annular split-ring spring 3. The casing l is generally cup-shaped and has a base 4 which has the greater portion thereof pressed out toprovide a number of attaching prongs 5 spaced inwardly from .the edge of the base so that there is an annular carrying medium engaging portion of the base located outside prongs 5, as shown in Figs. 2 and 4.
\ From the peripheral edge of the base et the metal curves downwardly to-provide a wall 6 and thenv outwardly `again to provide a ledge 7 substantially parallel withl the base 4.
The entire outer surface of the base 4, wall 6 and ledge 7 provides a support-engaging sur face which does not presentany sharp corners to themedium to which the socket isto be attached.
part located at the opposite side of the `cars` rying medium, as shown `in Fig. l. This cap or attaching part is pressed from a single piece of metal and has a central depressed portion 9 providing an annular anvil portion 10 generally curved 1n cross-sectlon. The
` peripheral portion of the attaching part is curved and the edge is turned underneath to provide a iiange ll extending inwardly and upwardly toward the anvil wall l0, as clearly shown in Fig. 2. When the parts of the installation are secured together the prongs 5 are forced through the carrying `medium 8 and against the anvil portion 10 which turns them outwardly and downwardly as shown in Fig. 2. Thus the carrying medium is gripped between two surfaces which do not present any 5.
abrupt or sharp angles opposite each other to cutthe material h when the parts are clamped between setting dies.
The cap has been made approximately theV i same diameter as the casing l, rather than larger in diameter than the casing so that the leverage exerted upon the ends of the prongs 5, by an upwardpull on the carrying medium 8, will be reduced to a minimum.
The result of my invention is an attach-V ment for fastening devices which reduces to.
a minimum the possibility of cutting or tearing the material either `during or after the attachment and a reduction in the possibility of an upward strain bending the prongs to loosen the attachment. y
The entire installation is reduced to a minimum number of parts and minimum i thickness. Furthermore the parts are so simple as to require a smaller number of operations in manufacturing and assembling while increasing the efficiency over other wellknown types of fastening elements and fastener installations.
While I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby, because the scope ofmy invention is best defined by the following claim.V
I claim:
A fastener installation comprising, in combination, a fastening member having a onepiece sheet metal part, a number of attaching prongs extending therefrom through a carryfst ing medium, thereby leaving the carryinglo medium imperforate except where the prongs pass through an annular carrying medium engaging surface extending outwardly, downwardly and then outwardly again from adjacent to said prongs, said annular carrying medium engaging surface presenting smoothly 'rounded curved surfaces at the bends, and a one-piece attaching plate located at the opposite side of the carrying medium, said attaching plate having prong turning and clenching means receiving and upsetting the said prongs to secure the parts of the nstallation together.
In testimony whereof, I have'signed my name to this specication.
MOSES F. CARR.
