and useful' 'lmprove'ments in CushionSpri11gs,

of'which the following is a specification.

"This invention relates to cushionr p rork for couches, beds, chairs, or the like. One ob ect oi the invention is to provide a constructlon and arrangement wherein the sides of the structure will be straight or at to the top and bottom.

Another obiiect ofthelin'vention-is to provide a construction and arrangement wherein.

not only the sides, but the ends, of the struch t angle Another object of the inve'ntionresides in the provision of an Xceedingly simple, inexpensive, light, dura le', rigid cushion-work for coucl1,bed, chair, and similar purposes.

Another object ofthe invention is to providelan arrangement of a number of convoluteorother springs within a wooden frame associating the springswith'a support and peculiarly-shaped stay-wires in such manner that theywill he s provide anarrangement and construction of such nature that when'pressure thelcushion it will be distributed. over the portion of the cushion surrounding'thatnpon which the'pressure is directly applied] Heretoior e' when single cone springs have been used in structures of the'present character the lower convolution or ends thereof have f'usually been secured to metallic, wooden, or similar slats in such manner as to permit the wider upper convolutions of the springs to extend out to or over the upper edge of the wooden orlike frame to meet the hhrderiwire or the like, ends of the cushion might be formed substantially at a right angle to the'top and bet- I am aware to arrange springs within a and support them therein with the outermost springs out oi contact with the trams and the border-wire. I am also aware have been. supported within a wooden frame without necessarily new, broadly,

surely connected there- .i still further object of the invention is tois applied to so that thesides and that it is not connecting them directly to the .irame or -to of thecharacter herein outlinedwg I- believe, however, that in my construction, wherein the double springs are employed and asso: ciated in rows and securely disposed upon corresponding pairs of support upper convolutions of each spring oi each corresponding row site sides to a peculiarlyatormed stay; which latter contactsnot on.y with. the opposite tion and arrangement notiheretotore erna ployed and one wherein perfect. resiliency and rigidity is manifest. 1 i

IWith these and other objects in view the present invention consists in the combination and arrangement of parts, as with be hereinafter more fully described, shown in the accompanying drawings, and; parli cue, larly pointed out in the appendedclaim, it being understood that changes in the form, proportion, size, and minordetails may be made within the scope of theclaim without departing from the spirit orsacrificing anyof the "advantages of the presentinvention.

in the drawings, Figure 1 is a top plan view of a cushion embodying my invention, the woodcni rame being removed. Fig. 2 a bottom plan view of the same, including the wooden frame. Fig. 3 is a transverse sectional view of the invention. Fig. 4 is a top plan view of a portion of a cushion, illustrating the manner in which. the end rows of springs are connected to the endsofthebon der-wireto present a substantially straight .'(-:11(l to the cushion.

By reason or the portions 3 of the support-wires being spaced from the inner face of the frame proper resiliency of the cushion is bad when weight is vbrought to 5 bear thereupon. Itwill now be understood that the su port-wires 2 are arranged transversely of. t e frame 1, and reference to the accompanying drawings will disclose that upon each pair of support-Wises double cone 1o springs 5 are mounted in series, v The compression of the springs in the present instance is uniform that is'to say, there isriv'cry little,

if any, tendency of a tilting of thefllower portion of the springs when I 5 to bear thereupon,"for t v support-wires extend beneath corresponding rows of s rings and are secured thereto at opposite e ges by means of suitable clips oi other elements 6. These clips 6 are made,

' 2o preferably, ofwire, and each is provided at its opposite ends with hooks 7 and an intermediate hook or kink 8, the hooks 7 being clamped, s rung, or otherwise secured around corres on ing support-wires and the lower 2 5 convo ution of the correspondingspring, the hook orkin 8 izceivingthe longitudinal su 'ort-Wires 9. kink '8 extends downwardly between the lower convolution of the correspondingspring and the outer face of the corresponding transverse support-wire,- the corresponding longitudinal support-wire being clamped, sprung, or otherwise secured into engagement with the kink and disposed below the transverse support-wires, asaolearly shown in Fig. 2. While one formof clip has been described for securing the transverse and longitudinal stay-wires and the corresponding springs together, it is to be understood that I do not wish to limit myself to the precise form of clip and that the clips may not necessarily be s rung into engagement with the aforesaid eementsdbut may be clamped or otherwise secured in connection therewith.

A border-wire, 10 is arranged above the frame 1, and. the side edge thereof are preferably in alinement with t e corres. ending outer edges of the wooden frame, the ends of the border-wire terminating in some instance substantially in alinement with the outer edge of the ends of the wooden-frame and in other instances not in alinement with the outer edges of the ends of the frame, as will be hereinafter more fully set forth. In any event, however, bridging the border-wire 10 and arranged transversely of the frame 1 is a looped stay-wire or other suitable pressuredistributing element 11, there being one of these elements 11 arranged immediately 6c above each transverse row of springs in the frame, and each is designed to rest upon opposite sides of the upper eonvolutions and springs. As shown in the drawings, the upper convolutions of the outermost set of o5 springs do not extend beyond the wooden pressure is brought.

siaaae frame 1, but are confined wholfy within latter. Thereforein ordert at thsherden wire 10 may be associated v tn the springs in such manner as to perm same has two points of contact'with the under surface .of the border-wireS, as at 13 and 14 in Fig. 1. This stay or pressure-distributing element 11 is practically endless, the ends of the same meeting at a oint Within the frame 1 and coupled together by means of a suitable coupling member 15. In other words, the pressure distributin element is in the form of a loop, the paralle sides there of being closed by rounded or other shaped ends, and, if desired, this element 11 may be formed of a single piece of material.

The clips 12, alluded to above, are each pro vided at their ends with hooks 16 and an intermediate hook 17, the'end hooks embrac ing the upper convolutions of the springs and also the corresponding sideof the stay or pressure-distributing element, the intermediate hook 17 being bent upwardly between the inneredges of the said convolution and over the corresponding side of the stay or distributing element, as clearly shown in the It will be observed that the looped stay or pressure-distributing element has its sides arranged above corresponding pairs of transverse support-wires, or, in other words, that the sides of the said element 11 are arranged along corresponding upper edges of corresponding rows of springs above and in a manner. similar to the arrangement described with reference to the transverse supportwires. The ends of the elements 11 which contact with the border-wire 10 are secured to the latter by means of the same form ofclips as that designated by the reference character 12. However, it is to be understood that theform of clips at the ends of the elements 11"may differ in form from those associated with the said element and the springs and that these particular forms. ofi'clips may be the samein form as the clips described and associated withthe support-wires and the lower convolutions of the springs. It is to be still further understood that these upper clips ma be sprung or otherwise secured in any suita 1e manner to their corresponding element's. Furthermore, the bottom clips may be the same as the upper clips, or modifications may lie-made with reference to thee s.

In the construction of spring-cushion work for couches the ends of the border-Wire need eiaaee The foot of thecouch is generally rounded over, so that ordinarily needed is on the sides. However, occasionally a construction may be formed Where the ends need to be even-that is to say, the

outer edges of the ends of the border-Wire.

should lie substantially over the outer edges of the wooden frame on said end, and in order to do this a different stay-wire than the looped stay or pressure-distributing element hereinbefore described is employed. For instance, a peculiarly-bent stay or pressureconvolutions of distributing element 18 is secured to the border wire and the upper convolutions of the springs in the manner clearly'illustrated in 'Fig; 6. It is obvious, therefore, that in the construction of a cushion wherein the ends of the border-wire are substantially over the outer faces of the ends of the wooden frame the form of stay or pressure-distributing element r8 should be employed and that when such an arrangament is provided the ends, as well as the sides, of the cushion are substantially at a right-angle with respect to the top and bottom of the cushion, providing a substantially rectangular cushion. Of course the stay or pressuredis tributing element 18 is disposed only at the end of the Work, the looped stays or pressure distributing elements 11 being arranged intermediate the ends of the Work. However, this pressuredistributing element 18 is bent in such ,man-

ner as to form parallelis ide members forengagement upon opposite sides of the upper a series of alining springs.

My peculiar arrangement possesses all of the desirable features of ever pressure is appliedto the cushion the pressure upon the edge Wire and the trans verse staywires'or other elements is directly .upon the edge of the springs,

rounding that upon which the pressure is directly applied, and therefore the farther the cushion is depressed the larger the area over the only extension insecure.

a spring-cushion for beds, chairs, couches, and the like, and when 1 sides of the tops of a which the pressure is distributed, andconse -f quently the greater will be the resistance 0 the cushion. A still further advantage resides in the fact that by reason of the peculiar connection of the cli ing elements the di erent elements are in place against accidental displacement. still further advantage resides in the fact that I am enabled to employ double cone springs in a cushion without the employ: ment of slats .for the support of the springs, which latter is a rather expensive arrangement, Moreover, when the springs are mounted upon slats it is the custom to tie'the springs together at their tops, all of which I eliminate. I gain an advantage, too, over the 'old method of supporting the springs upon webbing, necessitating the tying of the springs at their tops, this old method being In other words, it has been demonstrated that I can use support-wires formed in such manner as to be driven or otherwise secured in the framing of a couch, chair, bed, vehicle-seat frame, or the like and arrange the support-wires in such a manner as -to support the springs against tilting movement and securingthe latter to the other elements associated with ner as to provide an inert ensive construction. Furthermore, I am ena ledto arrange a series of double cone springs within a frameheld work and out of contact therewithand yet .be

enabled to produce a structureWvherein the same is perfectly rectangular in form;

I claim In a spring-cushion, the combination with a frame, of support-wires arranged in pairstherein, springs mounted upon corresponding pairs of support-Wires, means for securing the springs to the support-Wires, a'bo iderwire disposed above and in alinement with theiouter edge of the aforesaid frame, and a pressure-distributing; element comprising a single piece of side members for en agemen't with opposite ining-springs, the ends of the said element being forced. against the under face of each side of the bordervire by said springs, and means enga ing the said ends of said element and the si es of the bor-. der-wireto hold them together.

In testimony whereof I affix my signature in presence of two witnesses.
