'ilre housing adording open pockets for the espective springs so as to prevent the same from becoming disarranged or interfering with each other when being compressed or expanding, thereby assuring perfect resiliency to 'the' seat.

Another object of the invention is the provision or' a seat whereinthe' springs thereo` are nested in a novel in nner to sustain the same in proper wording position.

A, further object of the invention is the provision of a seat which is simple in construction, reliable and eiiicient in its purpose, strong, durable, and inexpensive in manurfncture.

l'itli these and other objects in view, the invention consists in the construction, cornloination'and arrangement of parts as will he hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

in the drawing-Figure l is a side view of the spring structure oi a seat constructed in accordance with the invention, with the cover removed. Fig. 2 is a top plan View 3 is vertical longitudinal secti nal View through the same. Fig. 4: is a fragmentary horizontal sectional view.

Similar Areference characters indicate coronding parts throughout the several the drawing.

'iieteiiring to the drawing in detail, the t comprisesspaced upper and lower similar luhstsntially rectangulanshaped frames o and 6 respectively, 4each ot which is prct erally formed from. a rigid rod, and these frames have arranged therein vertically di posed helical springs l which are positioned in parallel' rows, each spring being of the usual construction, and are connected together hy means of tie wires 8 which are fastened at their ends to the frames as shown.

revision of seat wherein the springs4 e eef are confined within a honeycomb-` The springs i are conti ned Within open cells or pockets 9 formed from opposed ilexihle strips 10, preferably made from canvas,

although they rlay be made from any other suitable tahric.l The@ strips 10 are stitched together as at 11 transversely thereof to provide the individual open cells or pockets for receiving the springs 7 so that they will be nestedand held in separated relation to each other to permit the compressing thereof or expanding of the same without interference with each other.

yThe open cells orv pockets 9 are open at their ends to permit of the insertion of auxiliary springs,y (not shown), ,within the springs 7, should the occasion require, resultant from hard usage of the seat, and thereby .increase the cushioning quality of the same. The :tree edges of the pockets are folded over the springs and connected therewith hy the tie wires 8 in the mannershovvn.

Any suitable cover may he employed to inclose the frames and springs, which cover is made in the usual mannen A 0, if found desirable, any number of iframes can be used to reinforcethe seat.

F rom the foregoingit is thought that the construction of my eevice will he clearly un derstood, and therefore a more extended e5:- planationhas been omitted.

'What is claimed is A seat comprising superimposed rigid `trames, springs arranged in parallel rows within the frames, flexiblek connected pockets receiving said springs, said pockets being open at both vends and having their free edges folded over said springs, tie wires bridging each row of springs at the opposite ends thereof and terminally connected to each of the said frames, and said Wires being formed to provide spaced pairs of coils loosely embracing the uppermost c0nvolutions of the adjacent springs at diametrically opposite points for connecting the 'free edges of the pockets with the springs and to prevent lateral displacement of the iatter,

ln testimony whereof l affix my signature in presence of two witnesses.
