J., assignor to Forstner Chain Corporation, a corporation of New Jersey Application May 15, 1936, Serial No. 79,902 1 vClaim. (01. 241—8) My present invention relates to spring belts, braces, suspenders, and the like, which have an elastic band, and has particular reference to a novel connection for attaching the elastic band 5 to the buckle and other ?ttings. It is the principal object of my invention to provide an improved and more efficient connec tion for attaching the elastic band to the other portions of the spring belt, whereby the parts 10 may be readily attached together and greater security against separation results. It is a further object of my invention to devise a very simple connection which can be readily manufactured at small cost, and which presents an ornamental appearance. With the above and other objects and advan tageous features in View, my invention consists of a novel arrangement of parts more fully dis closed in the detailed description following, in, 20 conjunction with the accompanying drawing, and more speci?cally de?ned in the claim ap pended thereto. In the drawing: Fig. l is a front elevation of a belt embodying 25 the novel connections; Fig. 2 is an enlarged view of one connection, showing the preliminary assembly; Fig. 3 is a perspective view of the buckle ?tting prior to assembly; and 30 Figs. 4 and 5 are perspective views of the bot tom and top plates forming the novel connection, the top» plate being in reversed position to show the locking tabs. Referring to the drawing, the belt includes an 35 elastic band Ill, a buckle ?tting H having the usual buckle l2, and a tongue ?tting l3 having the usual buckle openings Hi, the elastic band 10 being connected to the buckle and tongue ?ttings by means of connections I5. The elastic 40 band is preferably made of spring wire, having a plurality of spring turns or coils. Each con nection, see Figs. 4 and 5, includes a bottom plate l6 and a top plate ll, the bottom plate having a plurality of upwardly extending prongs l8 along one edge thereof, and two spaced teeth It at the other edge thereof, which teeth are adapted to be inserted into selected inner coils 26 of the elastic band ill, the teeth then being folded over so as to lock ?rmly about these coils. The buckle ?tting H, which preferably is made of leather but may be made of any other suitable mate rial, has suitable openings or slots 2| which are adapted to receive the prongs I8, these prongs being turned over if desired to lock the end con nection to the buckle ?tting; the lower plate It is preferably indented as indicated at 22, where by the upper plate ll may be positioned over the lower plate, with its two ends 23 extending along 10 the edges of the elastic band and the buckle ?t~ ting l I so as to conceal the joint, the ends 23 having tabs 24 which are bent over so as to be received in the recesses 22, whereby the connect ing assembly is completed. The invention is therefore particularly adapted 15 for articles such as belts, braces, straps, and the like, which articles require the‘ connection of an elastic to an inelastic member; both members be ing provided with openings, the lower plate has elements extending into the openings of the two members, and the upper plate is then locked to the lower plate so as to prevent separation or‘ re moval of the connecting elements of the lower plate from the openings of the two connected 25 members. While I have described a speci?c construc tional embodiment of my invention, it is obvious that changes in the parts, in the materials used for the parts, in their relative arrangement and 30 size, and in their operative relation, may be made to suit the requirements for different articles without departing from the spirit and the scope of the invention as de?ned in the appended 35 claim. I claim: In an article of the character described, in combination, a spring band formed from wire and having rows of loop coils, said loop coils having their axes perpendicular to the general 40 plane of the spring band, an end ?tting of flexi ble material, and a metallic connecting device comprising a bottom plate having lock elements for engaging said ?tting and teeth elements en gaging selected coils of said band, and a top plate cooperating with said bottom plate for locking the engaging parts in engaged relation.
