KRONHEIM CHAIR AND COUCH Filed Aug. 13, 1928 2 Sheets-Sheet 2 Gnome- Patented Dec. 10, 1929 JACOB KRONHEIM, on CLEVELAND, OHIO CHAIR AND COUCH Application filed August 18, 1928. Serial No. 298,227.

My invention relates to chairs and couches, and more particularly to an improvement in resilient seats or bottoms for upholstered chairs and couches. In general my purpose is to provide a resilient seat or bottom of sturdy construction which may be manufactured at a low cost and also installed with facility and dispatch in a chair or couch frame. Thus, the seat or bottom 9 is a separate transportableainit of predetermined size, which includes a series of coiled springs and a base of woven materials adapted to be suspended at different elevations within a chair or couch frame by a set of expansible springs and a set of wire clips nailed or screwed to the frame. As constructed the clips are adapted to be secured in various Ways to the frame, thereby permitting the resilient seat or bottom to be installed very readily in chairs or couches of different styles and kinds.

Thus the invention permits an upholsterer to either raise or lower a resilient seat or bottom within a chair or couch frame according to different upholstering needs, while affording at the same time an exceptionally secure attachment for the seator bottom within a chair or couch, all as hereinafter fully described and more concisely pointed out in the claims.

In the drawings accompanying this application, Fig. 1 is a top view of my improved resilient seat or bottom attached to a wooden chair frame, and Fig. 2 is a sectional view thereof, Fig. 3 is a side elevation and sectional view, enlarged, of a portion of the resilient bottom and frame. Fig. 4 is.a perspective view of a portion of the seat frame with one wire clip attached thereto in an inverted position. Fig. 5 is a perspective view of a clip having two eyes to permit two suspension springs to be attached thereto substantially as delineated in Fig. 2.

The general practice in constructing chairs and couches is to provide an open rectangular frame of wood or metal within and upon which a resilient seat or bottom is built by attaching strips of webbing to the bottom edges of the frame and then seating coiled springs upon the webbing. The springs are tied together after they have 'been placed within the wooden frame, from beginning to end involves constant handling of the chair or couch frame. My present conception is to produce a separate resilient seat or bottom made of a flexible base 2 of closely woven fabric stretched tightly within a wire frame 3 together with a top layer 4 of loosely woven fabric sewed to base piece 2 or to wire frame 3. Coiled wire springs 5 are seated upon base 2 and tied toget-her in definitely spaced relation by cords 6, while the bottom loop 7 of each spring is screwed into or interlaced with the open meshes of the top layer 4. The said pieces or parts are assembled and built up at the bench to provide a unitary structure of predetermined size, preferably somewhat smaller at base 7 than wooden frame 8 to permit a series of coiled suspension springs 9 to be stretched horizontally within the gap or space bordering three sides of the wooden frame. The inner ends of springs 9 are hooked to wire frame 3 and the outer ends thereof are connected to the side loops 10 of a series of wire clips 11 having their end portions bent at right angles and terminating in round eyes 12. Clips 11 are therefore adapted to embrace the rectangular rails of the frame with the terminal eyes 12 resting against the top and bottom edges of the rails, thus permitting screws or nails 14. to be easily driven vertically through each eye into the center part of the rail. Each clip is fastened securely in place by two nails and the pull of suspension spring 9 is applied horizontally to the side loop 10, which is located relatively near one end of the clip, see Figs. 3 and 4. Having a side loop so positioned, the clip may be used in two Ways, that is, loop 10 may be placed relatively near the bottom edge of the rail of frame 8, as in Fig. 3, or the clip may be inverted to place this loop near the upper edge of the rail, as in Fig. 4, thereby establishing either a high or low point connection for the spring seat or bottom within the wooden frame 8. The top of the seat may be placed in that way in either a higher or lower plane relatively to the chair or couch frame, thus permitting the upholsterer to adapt the seat to chairs and couches of different height 1 and the operation and kind and style. The clips are nailed at spaced intervals to the rails and the built-up spring seat is then connected to the loop 10 by the suspension springs 9.

The heaviest load on the seat is usually adjacent the rear of frame 8 and therefore, I prefer to augment the spring tension for the seat at its rear. For that purpose I connect two suspension springs 9 and 9' to the rear edge of flexible base-2 and the border wire 3 therein, see Figs. 1 and 2, and employ wire clips 11' having two side loops 10' instead of only one loop. One spring 9 extends horizontally and the second spring 9 is stretched at an inclination of approximately 45 as shown in Fig. 2. The front as well as the rear of the seat may be supported in that way, or I may nail coiled wire hooks 15 to the front rail 16 and connect the front border wire of flexible base 2 to these hooks as shown in Fig. 2.

\Vhat I claim, is:

. 1. A resilient bottom for a chair or couch having a frame, comprising a flexible base supporting a series of springs, suspension springs for said base and clips attaching said suspension springs to the frame of the chair or couch, the rear side of said base being suspended by two series of cooperating suspension springs angularly related to each other, and attached to side loops of said clips arranged above each other.

2. A resilient bottom for a chair or couch as described in claim 1, in which the front side of said base is supported by a number of springs with relatively little elasticity as compared with the elasticity of the other of said suspension springs.

In testimony whereof I aflix my signature.

. JACOB KRONHEIM.
