AndrewÍK. Sypien, Pittsburgh, Pa. „Application November 24, 1934,'Serial No. 754,618 3 Claims. (Cl. 155-184) '_ This invention relates to upholstered furniture, such as davenports, sofas .and vchairs ofthe loose cushion seat type as used in living rooms, 'hotel lobbies ëtc. Ll In ordinary practice, furniture of this kindis provided with a cushion support, commonly called in the trade platform, having a plurality of heli cal springs which rest on its bottoms on a laced webbing. The tops of said helical springs are tied together with a strong twine, coveredwith a single piece of canvas and ñlledwith moss and cotton and again covered with a single piece of canvas which is tacked to the rails of the chair or sofa. Before the top canvas is tacked to the side rails of the furniture the space between the two arms, the back and the platform is packed with moss or other suitable material, so that no gap exists between the platform and the arms and back. ' In the above described construction, a» great percentage of the ñexibility of ¿the springs near the arms and the back is lost,`due to this com pact packing. Another disadvantage of this con~ struction is when, for instance one of the helical springs or the tie-cord breaks, the platform has to be entirely ripped open when replacing defec tive parts. My invention relates Vparticularly to improve vments which overcome the disadvantages ‘out 30 lined aboveand the ob-jects of my invention :are as follows: LO The primary object of my invention is to pro vide'upholstered’furniture such as chairs, divans etc. with a removable platform-which .ishingedly 'attached to the 'front Vrail of said chairs, >divans etc. ' Another object of my invention is to >provide 40 to manufacture. . 10 With the foregoing and other objects in view this invention consists of the novel construction, combination and arrangement of parts, as here inafter set forth and more specifically described and illustrated in the accompanying drawings 15 wherein is shownsan embodiment ofthe inven tion, but it is ‘to‘be understood that changes, variations and modiflcations'can be resorted to which vcome withinlthe -scope vof the claims here unto appended. . «In the drawings wherein like reference char 20 acters; denote corresponding parts throughout the several Views: ' Fig/ure his a perspective general view of an upholstered ch-air illustrating the pad fiappèd 25 over .to expose the construction of the platform. .'Figurei 2 .is a similar view as outlined above, showing the platform ready for the reception of a cushion. vFigure 3'isa perspective view of a cushion.

Still another object of the invention is to pro vide a platform of upholstered chairs, divans, etc. which permits easy cleaning, thus making such furniture clean, mothpro'of and therefore 55 . `Still another object of the invention is to pro vide upholstered'chairs etc." in which the -lull bene fit of` the Ahelical springs is attained by eliminat ing the packing between the arms, the back and the platform 5 VIAnother object of my invention is to provide upholstered chairs etc. which are simple in con struction :and arrangement, strongV and durable, efficient Aand wconvenient in use and vinexpensive sanitary. and parts broken away; and ' inventiomwith parts eliminated and parts broken away. z `In carrying outmy‘invention, I provide a chair ,45 or divan frame 8, comprising the side rails 9, a :front :rail -.I.0,.a1rear‘rail VI I 4and the legs I2. At this time, it is Yimportant to mention that no change of the present method of construct ing chair or divan frames is required when using 50 my improvements, furthermore old upholstered chairs or divans may be readily altered or mod ified at low cost, without changing the structure of the conventional frame work of the same. A series of helical springs I3 are placed in the 55 2 2,107,087 usual manner, resting on a laced webbing I4, which is tacked to the underside I5 of the rail ings 9, IU and I I as shown in the various views of the drawings. The bottom I6 of said coil springs I3 is securely fastened on said webbing I4. The upper portions I1 of the outer helical coil springs I3 are connected at the edges by means of suitable connectors I8 to a stiff wire frame I9, which is of rectangular shape, similar to the 10 shape of the seat frame 8 and is preferably rounded at the corners, to fit partly around the helical corner springs, as best shown in Figure '7 of the drawings. The said wire frame I9 is fully covered with canvas 20, whichcovering extends 15 downwardly and is tacked to the upper edge 22 of the rails 9, III and II by means of tacks 2|. In order to prevent excessive forward swaying of the platform, the wire frame I9 is yieldingly held at the rear end by two sets of three coil 20 springs, one at each corner, arranged in a man ner as shown in Figures 4 to 6. The aforesaid arrangement comprises a pin-bolt 23, one end of which is pointed,.as at 24, and the other end 25 is threaded. 25 _ , This pin-bolt 23 is first inserted through the aperture 26 of the back-brace 21 and two coil springs 28 and 29 of proper proportions are slipped over the protruding end of said pin-bolt 23. The pin bolt 23 is then driven into the top 30 of the rear rail II and tightened by means of a nut 30. ` Should it be desired to make the said springs 28 and 29 adjustable an additional nut 3| may be placed below the back-brace 21, as shown in 35 Figure 6. Another coil spring 32 is hooked around the pin-bolt 23 between the coil springs 28 and 29 and fastened to the wire frame I9, in a manner vas best shown in Figure 6. A quilted pad 33, of similar outline as the seat 40 of the furniture and of uniform thickness with the exception of the two sides and the rear edge, is being employed in my invention and the under side of the front edge of said pad 33 is attached with tacks to the top portion of the front rail 45 34, so as to provide a hinged front end which will permit flapping over of said pad 33 when desired, as is clearly illustrated in Figure 5 of the drawings. . ` Referring now to Figures l and 5, pad 33 is 50 provided with thinned out edge portions 35 at three edges, so as to permit these edges toibe conveniently pushed under the arms and the lower edge of the rear or back of the furniture by pressing downwardly upon the pad, thus, a 55 seal between said platform and the arms and the back of the furniture being effected when pad 33 is in its final position. ' At each corner of the pad 33 I provide a metal ring 31 secured thereon (Figure 5) and under 60 neath the back brace 21 in near proximity vof the pin-bolt 23 I provide a 'small hook 39. When the pad is placed into final position as shown best in Figures 2 and 5, an elastic string 40 may be tied around said ring 31 and hook 39, this is to pro 65 vide additional means to prevent thefpad from wrinkling. ' In order to conveniently remove said pad 33 when it is desired to clean or repair the inside of the platform, I provide a loop 36 which isl sewed on the back edge of the pad as clearly shown in Figures 2 and 5. By taking hold of said loop 36 and by pulling frontwardly or to wards the operator the pad 33 will be released from its hold under the arms and the lower endV of the back of the furniture, thus exposing the elastic ties 40 due to its elasticity, and it is now possible to easily remove these ties from the 10 hooks 39. It is believed that the operation of the device will be readily understood, without a further de tail description of such operation, in view of the purpose and function of the different elements having been set forth previously. I only wish to add that the thinned out edge portions of the pad at the arms and back are pushed between the underside of the arms and back by depress ing the helical coil springs with the palm of the 20 hand. When released the said helical springs force the edges of the pad tightly against the underside of the arms and the back thus re taining the pad in a stretched position at all times.` - . I claim: Y 1. In an upholstered chair and the like com prising a substantially rectangular supporting frame, a platform mounted on said frame and including a plurality of seat-springs, side arms 30 and a back inwardly upholstered, a substantially rectangular padding covering said springs, said padding being permanently secured at its front edge to said frame, the other edges of the pad ding being free and tapered for ready insertion 35 and frictional engagement between the seat springs and the upholstered side arms and back of said chair. , 2.
