SPRING SEAT CONSTRUCTION Filed Feb. 23, 1938 Patented Apr. 2, 1940 PATENT OFFICE 2,195,759 SPRING SEAT CONSTRUCTION Wesley n. Schield, Glen Ellyn, 111., assigner to Kroehler Mfg. (30., Naperville, 111., a corporation of Illinois Application February 23, 1938, Serial No. 191,907

1 Claim. (01. 155-179) This invention relates to spring seat construction; and is adapted for use for davenports, chairs, sofa beds and the like, and consists of the matters hereinafter described and more particularly pointed out in the appended claim.

The object of the invention is to provide .a spring seat for the purpose which is capable of ready and economical construction, which is noiseproof and which is also dustproof.

These and other advantages of the invention Will appear more fully as I proceed with my specification.

In the drawing:

Fig. 1 is a top plan view of 'a davenport frame provided with the improved spring seat construction, the same being broken away at different places to illustrate the interior arrangement.

Fig. 2 is a bottom plan view of the davenport shown in Fig. 1.

Fig. 3 is a view representing a partial transverse section through the davenport in the plane indicated by the line 3-3 of Fig. 1.

Fig. 4 is a detail view on an enlarged scale, to be referred to more fully hereafter in the specification. Referring now to that embodiment of the invention illustrated in the drawing: l0 indicates the seat frame for a davenport with a back II and arms l2, l2 rigidly secured thereto, in a familiar manner. Said frame is mounted on front and rear legs I3 and B m indicates the rear rail, and ll] the front rail of the frame I, and In, H] indicate the end rails of said frame. [4 indicates a plurality of parallel, spaced metal straps extending transversely of the frame from the rear r'ail ll] to the front rail lil Each metal strap is rigidly connected at its front end I l to the front rail [0 (see Fig. 3). The other end of said metal strap is connected to the rear rail II] by a coil spring It indicates the springs which, as shown herein, are of the familiar hourglass shape and are disposed in the usual manner for connection to and support by the metal straps l4. Each strap has a plurality of prongs l5 disposed in spaced pairs, with the prongs of each pair separated by a distance equivalent to the diameter of the base loop 50 of a spring.

' N indicates a sheetof burlap which extends the length of the bottomframe I0 and is secured as by staples or tacks 18 to the end rails 10 I0 of said frame. Said burlap sheet is disposedupon terposed between the base loops of the springs I6 and said straps. The prongs I5 are extended through the burlap sheet I! and are bent about the bottom loops of the springs to secure the springs to said straps with the burlap ll between.

The burlap sheet covers the entire space occupied by the metal straps 14, extending from 5 the front rail 19 of the frame to the rear ends .of said straps. A margin ll is turned up at its front edgeand is tacked or stapled to the rear face of the front frame member it as shown in Fig. 3. At its rear edge it is turned upon itself 10 and hemmed to provide a longitudinally extending opening to receive a rod or wire l'l as shown in Fig. 4. Said wire is held'in place by hooks l4 formed at thefront ends of the coil springs M and engaged from below through the openings 15 formed when the proximate prongs l5 are cut from the metal straps I4, andthrough the burlap sheet above the same. Thus the burlap sheet is held securely in place at all edges to enclose at the bottom the space occupied by the springs, and prevent dust from entering saidspace. In addition, since the burlap. sheet I! is interposed between the base loops of the springs and the metal straps 14, there is no noise'due to the metal of 25 and a top cover secured to said rails, a plurality ofspaced, parallel metal straps extending transversely of said seat frame in a plane spaced below said cover, means rigidly connecting the forward ends'of said metal straps to the front rail, coil springs pivotally connecting the rear ends of said metal straps to the rear rail, said springs having hooks engaged with said straps, a sheet of textile material entirely covering said plurality of metal straps and secured at its end and front margins to the end or side and front rails of said frame in g closed relation thereon, said sheet of textile material extending from the front rail to the rear ends of said metal straps and having its rear margin provided with a hem, a wire extending longitudinally through said hem, said hooks being engaged with said wire, a plurality, of expansion springs resting upon said sheet, and means for securing the bottom loops of said springs to said metal straps with said sheet of textilematerial interposed between the bottoms of said springs and said metal straps. a
