575,622. Fastenings. UNITED-CARR FASTENER CORPORATION. Nov. 3, 1943, No. 18236. Convention date, Oct. 23, 1942. [Class 44] A fastener member, particularly but not necessarily of rotary stud and socket type, is provided with a case having spaced bearing portions and is attached to a plywood or other non-metallic support by attachment members, each of which has integral prongs extending through the support and clinched therein, means being provided passing through the attachment member, or the bearing portion, of through both, to secure them rigidly together. The invention is described as applied to securing the socket member of a rotary stud cowling and like fastener to a non-metallic support 15 to which a cowling or like panel 14 is to be detachably secured, the socket shown being of the kind described in Specification 557,676, and engaged by radial arms 12 of the stud 10 rotatably mounted on the panel. The base of the socket has spaced extensions or bearing portions 19, shown in Fig. 1 as bearing against the inner face of the support. Each attachment member comprises a disc-like plate 26 secured to the bearing portion by rivet 25a and having integral prongs 28 which are forced through the support and clinched over as by an anvil plate pressed against the outer face of the support as the prongs are being forced home. In modifications the attachment member has an integral tubular rivet portion adapted to be passed through an aperture in the bearing portion and riveted over, one arrangement having the attachment plate overlying the bearing portion as in Fig. 1, the tubular rivet being downwardly directed, and in another arrangement having the attachment plate below the bearing portion, which rests thereon instead of directly on the support, the riveted portion being upwardly directed. |
