CUSHION.

Application led September 16, 1919, Serial No. 324,151. Renewed February 17, 1923.

illustrated in the accompanying drawings,

forming a part thereof.

The invention relates to cushions for vario'us uses and is illustrated as taking the form of a pillow. It consists broadly of a resilient body formed of wire fabric and having the form of a cylinder or modification thereof, and being enclosed in an enveloping pad.

Other features of the invention will hereinafter appear.

The invention is illustrated in the accompanying drawings, in which g- Fig. 1 is a detail in perspective of the re- Fig. 2 is a View in perspective of the cushion taking the form of a pillow, a portion being broken away to show the internal construction Fig. 3 is a cross sectional view of the pillow shown in Fig. 2.

The resilient element of the cushion, a detail of which is shown in Fig. 1, consists of a plurality of helical coils of spring wire arranged in two sets of parallel rows whlch intersect preferably obliquely, forming a fabric having a diamond shaped mesh. At their points of intersection the coils 10 11, are interlocked as by a screw action, a plurality, as shown two, of the turns as 12, 13, of the coil 10 enclosing a corresponding number of the turns as 14, l5, of thel coil 11. By reason of this plural locking of the two sets of coils, the fabric maintains substantially the original form of its mesh even under tension in any direction. This fabric may be woven flat and then given the desired form, the meeting ends being secured together, or, and preferably it is, formed as a hollow body 16, without seam or joint, the several coils extending fromn end to end of the body and each following a spiral direction as indicated in Fig. 2.

The hollow body may have the form of a cylinder or may be flattened to the extent desired for the particular service for which it is intended. When it is to be used as a pillow it is given the oval form shown in Fig.

8. This hollow body is enveloped in a pad 17 of a textile fabric or felt, of such thick-- limit the yielding to pressure to the exure f of the longer sides either wholly or partially depending upon the character of the stays as to elasticity or length. This cord may be of any suitable material such as string, wire, or a chain, and may or may not be elastic.

Such pillows are exceedingly comfortable to the user, being soft but comparatively firm and donot become heated. y

The invention may be readily a plied to cushions for chairs, chair seats and) arms or may be used in mattresses.

The word cylinder as employed in the appended claims is not intended to have the restricted and technical meaning as it is defined in the dictionaries, but to include other than forms which are circular in cross section, such as an oval.

I claim as my invention- 1. A cushion comprising a cylindrical resilient element formed of helical coils of spring wire, the coils being arranged in two sets, those of each set being parallel and the coils of each set crossing those of the other set obliquely and being interlaced therewith,

two turns of each-coil enclosing two turns of the other. v

2. In a cushion, in combination, a hollow cylindrical element, the walls of which comprise a fabric of spirally arranged helical coils extending in a. plurality of directions, a plurality of the turns of each helical passing through turns of the other helical at interections of helicals and an enveloping pa 8. A cushion comprising a hollo cylindrical element the walls of which coifiprise a fabric of spirally arranged helical coils extending in a plurality of directions, a plurality of the turns of each helical passing through turns of the other helical at intersections of helicals.
