SPRING-CUSHION.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application ined July 1o, 1916. seran N61 108,330.

i To all 'whom z't may concern.'

Be it known that I, FRANK P. DAncr, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Spring-Cushions, of which the following is a specification.

This invention relates to improvements in spring cushions.

The main object of this invention is to provide an improved spring cushion of the pillow type in which the springs are effectively supported so that both ends of each spring are free to yield or move independently of other springs.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of m invention by the devices and means descr1bed in the following specification. The invention is clearly defined-and pointed out in the claim.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a perspective view of a spring cushion embodying the features of my invention.

Fig. II is a detail section thereof on a line corresponding to line 2-2 of Fig. III.

Fig. III is a detail view on a line corresponding to line 3-3 of Fig. II, showing structural details of the spring structure.

Fig. IV is a detail perspective showing further structural details of the spring structure.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referrinv' to the drawing, I provide a casing, preferably comprising an inner wall part l, a covering Q,.and a filling 3 between, thelling being on both sides and on the edges. This casing contains a spring struc-' ture consisting of double helically coiled springs et arranged in rows, the springs of the several rows being alined. These springs are supported in proper relation to each other and held upright by the Wire supports 5 and 6 arranged in pairs in a transverse or crossed relation. These support wires have hooked loops 7 formed therein and engaged over central coils of the springs. The ends `Ialong practically any line.

of these support wires are secured to the central coils of the outer rows of the springs at 8 and are preferably provided with hooked loops 7 engaging the central coils of the outer springs, as clearly shown in Fig. III.

I preferably provide only one support wire for each row of the outer springs and dispose this at the inner sides of the coils, as shown in Fig. III. The support wires are secured with their hooked loops in engagement with the coils by means of the locking wires 9 which are disposed across the central coils engaged by the hooked loops of the support wires and threaded through the bights of said loops, the ends of the lower wires being secured to the central coils 0f the outer rows of springs at 10. By this arrangement the springs are supported so that both ends are entirely free to yield independently of other adjacent springs, thus providin a structure which, while the springs are e ectively supported, secures the full benefit of their resiliency.

rIhe loops 7 are shaped so as not to distort the central coils of the springs, certain of the loops being longer than others (see Fig. III) thereby permitting the coils to lie in their normal spiral position. The supporting and locking wires are resilient and of suchl diameter as ermits their being flexed so that the cushion may be flexed or curved as a whole. As the supporting and locking wires are secured to the coils of each s ring at points which lie substantially in tie same plane the cushion may be flexed y This action is facilitated by reason of the fact that the ends of the coils are free to yield independently, that is, they are not in any way connected with each other. There being no edge or border wires the edge of the cushion is soft and flexible and the springs being supported entirely by central coils, each spring yielding independently under pressure, a very soft and flexible cushion is secured, so that the structures may be effectively used as pillows, chair cushions. or couch upholstery and the like.

My improved spring cushion is very simple and economical to produce. The springs are supported so that their full resiliency is secured and, both ends of each spring being entirely free, comparatively heavy springs may be used without rendering the structure too stili' or unyieldng.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is:

-In a cushion, the combination with a casing, of a spring strueture'disposed in said easing and comprising double lielieally coiled springs arranged in rows, resilient 'support wires connecting said springs disposed in pairs in a transverse crossed relation and secured to central coils in the rows of springs so that said springs are supported in an upright spaced relation, the outer ends of the springs being disconnected and free to yield independently, the` spring structure being capable of being flexed as a whole by the yielding of said resilient support wires.

In witness whereof, I have hereunto .set my hand and seal in the presence of two witnesses.

FRANK I. DARUY.
