To all whom, it may conce/m.'

which double Webs serve u. further function Be it known that I, Fnunnnicu BENNETT, nvenswood, county of Queens, Stute ol New. York, have invented Acertain new ond useful Improvements in` Cushions, of which the following is :t full, clear, and exact specification, such as will enable others skilled 1n the art to which it. appertains to make :1nduse the sil-nie.

My invention rel :ttes to a cushion intended particularly for seats in cars and other pubof cushions. in which a. frame carries =a.'nl1mb eI-.cf springs over' whichj flexible steel or iron sheetsy are arranged furnishing izilexiblesupport for the covering of woven; rotan or. such-other material ns maybe e "ployed to c o'ver..v the cushions. i l i .z f

The lending .1s to construct such cushion Wholly of metal 2" be cheap f to manufacture V'n'nd yetfstrtn/ig 'nd'flivht "find-v furnishing nmplcjresilierwy. Q:

. My invention involves other' feature import ance, alla of which'. WilliA be.;

:ls will fully appear hereinafter.

The frame stripis formed inthisA incliner, Iii-st in n straight.' length and is then bent into square, rectangular or other form and its ends ure lnbutted together and suitably fastened. To ncconiplish this, the fiunges 10 and V13 of the freine strip at the points Where the bends are to be 4foiined'nre cutor slit "us indicated :it lnnd 16 in Fig. 11, leaving the n'ebs 11 und 14 intact. The webs 11 and, 'T14' nre the-n b e'nt fus indicated by the broken lines in Fig #landthe slit. ends o'f` the {lung-es 10 and l2 are cuusedto 'over-lap each V f other.

' i Extending against. the 'frame und .on the bottom .liunge 12 supports 19. These resting the cushion generally couo1-'rectangular und is made up in u peculiar manner of n sheet metal strip. This strip is folded or bent longitudinully to producen top fia-nge l0, :i vertical main web 11, a bottom liange 12 and a. secondsry vertical web 14. These parts are all formed of au integralsheet of metal by making the requisite folds therein. The webs-11 und ltlie against euch other and the Iinngc" 1i' has a double thickness produced by bending the metal upon itself as shown in the drawings, and particularly in F ig. 4,' This produces an extremely rigid structural for'm, having the' strength of channel or'U-iron` 'llle Atranne of spring supports are constructed of metal sheets with their edges turned up to vforni flanges Q0 which strengthen the supports; and the ends o`f the supports :1re lirxulv riveted to the fianges 12 :is indicated at Suid spring supports have tongues Qinstruck up from them and these are adapted to be bent over the bottom convolution of the spiral springs 21. here shown there ai'ejthree spring vsupports 19 and three springs for each support. Said springs taperupward 'and ere seated on the supports between the tiange's 20. -By mesns ofthe tongues 23, the 4springsfare readily seund n mliing rigid connection :it this point.

thereof are spring 1 ion strips 27 are thus supported by springs ened'as the drawings show, the upperedge double webs, I not onlyfgreatly increasethe and cheapness than any cushion heretofore tical; and the lower Harige having a double g thickness formed -by ben spring supports 19 and the` ends of the cushion-strips are bent downward as indisare then riveted by fastenings webs. To prevent the upper edge of the web longitudinally to cured and by a method which is cheap and effective.

At their upper ends the springs engage buttons 25 and these are fastened b rivets 26 to the licxible cushion strips 27. f these strips there is one for each row of vsprings 24' and'f'said vstrips are preferably transversely corrugated to give them flexibility, and also to furnishbearings for the raten orvother covering of the `cushion. The resilient cushand the combined elasticity of such parts amply produce the necessary yield or give tothe cushion. The cushion strips 27 eX# tend across the top of the frame 'from one side to the other .thereof Vparallel with the cated at 28 and introduced between the u per edges of the webs 11 and 14. These en s 28 which pass \through said vends and through both of the 11i-from projectin toutward, .owing to the insertion of the en s of the strips 27 and thus preventing a ,sharp edge, said web'is shortlying below the upper extremity ofthe web 11. It will therefore be seen that Aby providing the frame of the cushion with the Known. l

Havingthus described my invention what I claim as new and desire to secure by Letters Patent of Ithe United States, is:

1. A cushion, the frame whereofis oonstructed Aof a single piece of sheet metal bent lproduce a channel or U- iron cross-sectlona ing the meta-l upon form, the web being verlongitudinally to producev a channel or U- iron crossfsectional form, vthe web being vertical and the lower fla-nge having a double thickness formed by bending the met-al upon itself, and such metal extending from the base of the lower flange upward along the said web to form a secondary 'or auxiliary web, springs, means forA supporting them o n the frame and avc'ishion element extending over the springs, said cushion element' consisting in a strip, theends .of which are extended into the. space between the first- -na-med and secondary webs of the frame and fastened thereto.V Y

3. A cushion, coin rising a frame having vertical walls and)V anges constructed of a singlepiece of sheet metal, the lower Hanges and vertical walls being reinforced by'bending the'metal back and upward upon itself, spring-supports seated upon vthelower Hannes, lsprings securedupon the supports, and a cushion element-,supported upon said springs and secured. between the double vertical walls of theframef 4. A cushion-having a frameformed'of sheet metal folded longitudinally to produce a channel with a vertical web and horizontal extending flanges, the metal forming one of said flanges being bent back upon itself to form said .liange of double thickness and both of said flanges being cut transversely at a plurality of points at which point-s the web is bent' to form the corners of the frame, causing the adjacent portions of the fianges to loverlap one-another, and means for securing` together said overlapped portions.

In testlmony 4whereof I have signed my name to this specification in the presence of two subscribing witnesses.
