MATTRESS.

Application filed February 4, 1924. Serial No. 690,654.

To all 'whom t may concern.'

Be it hereby known that we, CHARLES,` Z. EDELsoN, JACOB GOLDEEN, and MILTON D. TARLow, citizens of the United States, and resident-s of Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Mattress, of which the following is a specification.

This invention relates to the art of mattress making.

An object of our invention is to provide an exceedingly simple and eiicient mattress which will -neither sag or stretch.

A second object is to so construct the mattress that there will be a movement of air within the mattress whenever any of its portions are compressed or released.

A third object is the utilization of' air within the mattress as an insulating medium which will make this mattress warm in cold weather and cool in warm weather, owing to the fact that the air filler can absorb and retain only a small amount of heat.

A fourth object is the utilization of springs having initial tension which are conlined within each biscuit7 of the mattress between a pair of convex covers,l which covers are also the spacing means.

A, fifth object is the centering of the springs in the various biscuits, and to make it possible to employ roll edge and tufting machines now in common use in the art.

A sixth object is to so construct our mattress that every part of same will be employed in lending resiliency thereto.

A seventh object is to combine the spring element with the means for limiting the eX- pansion of the springs.

1n addition to these objects we have endeavored to maintain the utmost flexibility and resiliency in the mattress, and at the same time make same reversible.

Reference is made to our application No. 681,684 dated December 20, 1923, over which this device is an improvement.

W e accomplish these results in the manner set forth in the following specification and illustrated in the accompanying drawings, in which:

Figure 1 is a plan of the mattress of which Figure 2 is an end elevation and Figure 3 a section along the line 3 3 in Figure 1. Figure 4 is a plan of one unit assembled. Figure 5 is a front elevation of the unitwith a portion broken away for clearness.

Similar numbers of reference refer to the same parts throughout the several views.

Referring in detail to the drawings, in its preferred form our invention consists of a closed horizontal outer ring` 10 of octagonal form in which are placed the opposed convex covers 11. rihe double bow springs 1Q, whose coils 13 pivoton the rings 10, are attached at their extreme ends 14 and 15 to the covers 11 by curling the edges 16 of the cover inwardly over the bent ends of the spring 12.

It will be observed that the union between the springs 12 and the covers 11 is not rigid but hinged, which construction permits a great variety of movements of the cover 11 without injury to same, and also permits the springs themselves to support their portion of the load along their lengths instead of transferring the load to the covers 11 themselves.

Of course it can be readily seen that with this construction of spring, one end will be closed and the other open. @n the closed end the spring hinges to alternate parts of the curled edge 16, and on the open end all of the free ends are preferably turned in one direction to facilitate assembling.

At alternate corners of the ring 10 we 4have provided the fiat face 17 which is joined by the coupling ring 18 to a similar bend on an adjacent ring 10.

In the usual size of mattress fort-y such units are employed, as shown, but this, of course, can be varied to suit the taste, the allimportant point being the unitary construction by which each biscuit is enabled to operate independently of all of the rest, thereby preventing the stretching and sagging which is common in mostmattresses.

VVhen as many units of the device havev been assembled as there are to be biscuits in the completed mattress, the assembled device is covered with light cloth 19 and one or more layers of the desired filler 20, after which it is placed in the ticking 21 and tufted and roll edged as is the common practice.

In some cases it may be found desirable to employ more iller on one side of the mattress than on the other or to increase the number of turns of the spring coils 13 on the octangonal ring.

These :1nd other minor ehnnges, such as the style of couplingl ringl 20, the shape of the ring l0, ete. nnty he varied vv'ithont depurting 'from theI spirit ot om' invention.

A, n'mttress eonstrneted es above deserifoed is free to be rolled in either direction or heut in any ii'orni without danger of injuring the mattress.

Giving' to the lfzivt that initial tension is supplied to the spring' i2 it Afollows that any slight wmkening olf o spring, diie to con stent use, will siill leave sniiieient ,strength to bring' the over ih :1nd oif Coni .1 biscuit np to the proper position. t if'illovfs thsii ilI env oi. ihe hisvuiis fir-pres l independei i' olf :inv et the other biscuits 11nd will reti n to it 1l nosi tion thm` it '11 piijvsieei iinpoisii the mattress to stretch or io rThe size ot the eoil i3 ieient to peiIH mit its lateral nieve-,ment en the ring; Cn ,in its normal position it limits the siipiii'iiiiin of the covers lfi sind in its outward position it transfers the thrusts from the springs l2 to the sides oi the oetngonzil "ing, whieli it self acts :1 spring;` ol'lfei,.zg :i yieidinjg; resistance to complete depression o if the cap ll.
