SPECIFICATION forming part of Letters Patent No. 564,380, dated July 21, 1896.

Application filed November 6, 1894. Serial No. 528,035. (No model.)

To all whom it'may concern: or supports E, preferably curved downward Be it known that 1, JOHN S. JOHNSTON, a to increase the capacity of the frame,as shown, citizen of the United States, residing at Chiconnecting the side bars D D between the end cago, county of Cook, and State of Illinois, bars 0. Upon each of the end bars 0 O and 5 have invented certain new and useful Imeach of the crossbars Eis mounted a row of provements in Seats, fully described and repvertical coiled springs 60, having their smaller resented in the following specification and the ends next the seat-frame and connected to the accompanying drawings,forming apart of the side bars and cross-bars, preferably by having same. their straight ends inserted into holes in the IO The especial object of the present invention bars, the downward pressure on the springs is to provide an improved construction of seatbeing suficient to retain them in place withcushion especially adapted for car-seats and out clinching the ends.

Referring now to the specific construction Over the springs a, spring-plates b, and of the seat-cushion in which the present inedge plates 0 a cover (I of textile material vention is embodied, C O are the opposite preferably canvas, is drawn and secured to 50 end bars, and D D the opposite side bars, of the side and end bars of the seat, so as to the seat-cushion frame, a series of cross-bars hold the springs in place and under the proper tension, the central springs being of greater length than the edge springs, so as to give the proper rounded form to the cushion. Upon this canvas (Z the packing or stufling e is supported, and outside this the plush or other cover f. It will be found that this c011- struetion provides a very efficient, comfortable, and durable spring-edge cushion.

The back-cushion shown in this application forms no part of the present invention, but is described and claimed in another application, Serial No. 551,058, filed May 31, 1895, now Patent No. 542,412, and it will be understood that any other suitable form of backcushion may be used in a reversible seat hav' ing a seat-cushion. embodying the presentinvention. As shown in Fig. 2, this seat-back has the top and bottom bars G l and series of crossbar-s II, on which bars are supported the top and bottom edge springs g and the body-springs '1', these springs being shown as having their top coils connected to rods 72 71: by clips at and held under tension by bands 0, connecting these rods to the frame. Over the spring-body thus formed is a covering of textile material. 1), upon Which is supported the fillings and the plush or other covering 1'.

It will be understood that modifications may be made in the construction without de- )arting from the invention, and I am not to be limited to the exact form or arrangement of the parts shown.

W hat is claimed is l. The combination with a cushioirframe consisting of side and end bars and a series of crossbars, of coiled springs supported on said bars and arranged i 11 rows, diagonal links connecting the springs in sets and crossing centrally oi the sets of springs, edge plates secured to and supported by the outside springs and of such width as to be rigid sidcwise while flexible longitudinally, said plates being secured together at their corners to form a frame extending about the cushion, and a flexible covering and upholsterin g supported on the spring-body thus formed, substantially as described.

2. The combination with a cushion-frame consisting of side and. end bars and a series of cross-bars, 0i coiled springs supported on said bars and arranged in rows, diagonal spring-plates looped about the top coils of the springs in sets of four springs and intersecting centrally of the sets of four springs and secured together at their points of inte1- section, edge plates secured to and supported by the outside springs and of such Width as to be rigid edgewise While flexible longitudinally, said plates being secured together at their corners to form a frame extending about the cushion, a flexible covering over the spring-body thus formed having its edges secured to the frame, and upholstering supported 011 the flexible covering, substantially as described. I

3. The combination with end and side bars and cross-bars E, of coil-springs on said bars arranged in rows transversely and longitudinally of the cushion, diagonal spring-plates 7) connecting said springs in sets of four and crossing centrally ol' the sets of four sprin said plates being looped about the top coils of the springs and the ends of intersecting plates being secured together at the point of intersection, edge plates 0 flexible longitudinally and rigid edgewise extending about the cushion and carried by the outside springs and secured together at the corners to form a spring-frame extending about the cushion, substantially as described.

4. The combination with end and side bars and cross bars E, of coil-springs on said bars arranged in rows transversely and longitudinallyot' the cushion, diagonal spring-platcs 1) connecting said springs in sets of four and crossing centrally of the sets of four springs, said plates being looped about the top coils of the springs and the ends of intersecting plates being secured together at the point of intersection, edge plates 0 flexible longitudinall y and rigid edgewise extending about the cushion and carried by the outside springs and secured together at the corners to form a spring-frame extending about the cushion, cover (.1 of textile material extending over the springs and plates and having its edges secured to the bars, and upholstering on said cover, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JOHN S. JOHNSTON.
