This 4'invention relates toichairsandsiii'ilar furniture and has foriits main object topra-y vide novel devices in 'tlieseats v'of such furniturewh'ich improve its `cushioning, resilient "l5 and"elastic/allyyieldingqualities. v l Another object of my invention is to provide a device of the mentioned character which will be easily accessible forcleaning purposes andpartsof which will be easily eri- 30 changeable. Still further objects 01'? this inventionv are to provide a device as characterized herein! before which willb'e simple in construction, inexpensive to manufacture and to `attach to fr# furniture, which win be adapted to be en ployed with the usual chair seat constructions at present in use,`andlwhicli will be adapted. for attractive Vseat constructions for furni ture. i

Referringnow more closely to the drawing by characters of reference, the preferredv form of my chair equipped "with Amy im'- proved seat construction shows yaseat frame indicated in generalby the numeral 10, front legs 11, rear legs 12S secured to said frame', arm rests 13 and back 14. A back cushion or pillow 15 and a seat cushion or pillow 16 may be placed on the respective parts of my chair ma to give it anupholstered eifectand usefull# I IleSS.

Cushion 16 may be easily removed whereupon the whole structure ofthe seat will be exposed, and upon folding upwardly or' temporarily removing the circum ferential covering strips 33 the ends of the transversal straps31 and32 are at once accessible and every individualstrap 31 or 32, or their springs, may be easily removed and replaced or exchanged.'

It is also obvious that the cleaning ofthis seat construction can be done easily and efciently, leading not only to easeand comfort in use of -my chair, but also to a highlysanitary condition thereof.

In Fig. v, I show a modification of the construction of the ends of the straps-31 or32, said ends being here enclosed between the two sides of a doubled piece of sheet metal 35, the same being secured to said strap end by sharp teeth 36 being struck out of its material into said strap ends, and also by rivets or other Jfastening means 37. A metal hookV 38 may be secured on the outer end of said double sheet metal piece 35 to receive the inner end of the respective spiral spring 26.

In Fig. 6, a further modification ofthe construction of the ends of straps 31er 32 is illustrated and in this construction said strap end is doubled upon itself, as at 39, and two sheet metal plates 40- and 41 are placed above and belowuthesame, respectively, and preferably secured thereto by the rivets 42. V The end 43 of said doubled portion is left freefso that it forms a loop through which is placed a wire ring 44, said wire ring to receive the mentioned end of the respective spiral spring 26, as vhas l been described 'hereinbefore In Figp7, finally, I illustrate onev form of the application of my device to metal furniture. rIhe respective frame member is here shown as a metal tube 45 to which I preferably securean ear piece 46 having an aperture 47 therein into which the outer end 27 of the respective spring 26 maybe hooked.

It will be understood that changes and variations may be made in th'e'parts and combinations of my invention and I hereby reserve all my rights to any and all such changes as are within the spiritof the invention and the scope of the appended claims.

'Y -What I claim as new, is:

1. In a chair or like furniture, Vin combi nation with a removable cushion and as a base for it, a seat frame having opposingly placed members; a plurality of straps placed transversely between said members; a spiral spring for each end of each strap, said spring having downwardly turned hook extensions at both ends, each of said frame members having a plurality of holes and each of said straps having a hole at each end, the downwardlyturned ends of said springs being removably inserted in the respective holes.

k2. In a chair as set forth in claim 1, rabbets formed in the frame members, said holes in the frame being on the horizontal surfaces of said rabbets, and said cushion partly resting on'said vhorizontal surfaces enclosed by the vertical walls of said rabbets.

Signed this 15th day of June, A. D. '1931.
