CUSI-IIQN SUPPORT.

Application filed July 8, 1924. .Serial No. 724,983.

This invention relates to that class of seat A rectangularly shaped textile section 3, or cushion supports in which a series of which, in the present instance, will be of coiled springs, having coils of uniform dilight weight, such as cheese cloth, is proameter, are arranged side by side with their vided, the width of which is somewhat 60 5 adjacent coils connected to hold them in greater than twice the height of length of proximity. In this class of devices, ithas the spring when expanded to the-desired exbeen the practice to enclose each spring in tent, and the length of which is slightly a textile casing, principally to limit the exgreater than the length of the periphery of pansion thereof to a uniform extent, and, the spring. In assembling the spring and 65 prior to my invention, it has been customary, cloth section thus provided, the latter is in doing this, to divide an elongated cloth first passed through the collapsed spring bag into compartments by transverse rows coil, as shown in Fig. 3 and then doubled of stitches, and then to pass the end of a about one side portion thereof. The end wire spring through the material into each portions are then laid one on the other and 7 compartment and screw it into the same by sewed together in a sewing machine by a turning the spring about its center line. On row of stitches 41, as indicated in Figs. 4 account of the diflicult-y of performing this and 5.

The casing is then drawn over the The object of my invention is, principally, spring until its ends meet and the coils are to provide an improved means and method completely covered. The casing-ends may of enclosing springs of the character above then be fastened together if desired, but 3 referred to in a cloth casing, which will be this is usually unnecessary. By this arrange simple, eflective, and durable, as compared ment the spring will be completely enclosed with previous methods and constructions by a casing which lies against its exterior and which will enable the encased springs and interior peripheries and the expansion to be readily attached to each other, so as of the spring beyond a certain point will be 90 to form a yielding surface of any desired restrained at all points by two plies of the ar a cloth. When the spring is distended the I accomplish this object in the manner connecting seam 4 of the casing will usually hereinafter described, and as illustrated in be held midway of the ends of the spring, the accompanying drawing in which: as shown in Figs.
