SPRING MATTRESS AND LIKE STRUCTURE.

Application med iruiy 12,

. My present invention has relation to the improvement of that class of spring mattresses and cushions in which the resiliency of the structure is secured by means of a plurality of coil springs arranged within an inclosing casing. The object of the invention is to provide improved means for securely holding the springs in proper relative position wit-hin the casing. lI he invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawingr and particularly pointed out in the claims at the end of the specilication.

Figure 1 is a view in lvertical section through a portion of a mattress or cushion embodying my invention. Figure 2 is a plan view. Figure 3 is a view in vertical section on line 3 3 of Fig. 1. Figure 4 is a detail perspective view showing the type of staple preferably used for uniting certain of the parts together.

The casing A within which the coil springs B are inclosed will be formed of ticking or like textile material. As shown, this casing is surrounded by aY pad C that is secured ,in usual or suitable manner to the casing, as by tufting cords D. To the upper and lower walls a and a of the easing A are fastened flexible strips of flexible material E, these strips being preferably formed of heavy webbing or tape. In the preferred embodimentv of the invention, the strips E are united to the walls a and a of the casing A by meandering, preferably sinuous lines of heavy stitching e. These lines of stitching c, as shown in Fig. 2 of the drawing, are curved so` that at different points they approximate the upper edges of the strips .E and at their points 'approximate the inner edges of the strips E. In this way, pockets are formed between the strips E and walls a and a of the casing A to receive the terminal coils b of the springs B, the walls or pockets thus produced conforming approximately to the curvature of the terminal coils of the springs.

The strips E of the webbing or like material are also preferably secured to the walls a and a of the casing A by staples F, the pointed ends f of which, after being passed through the webbing and the walls of the casing, are clenched, as indicated in the drawing. These staples F are arranged at a suflicient distance between the outer walls of the pockets formed between the strips E and the walls of the casing A to permit the terminal 1924.' serial No. 725324..

coils b of the springs to be inserted between thelouter walls of the pockets and the staples. As shown, strips E and the walls of the casing A are arranged to face alternately in opposite directions and-the springs B are disposed in nested relation so as to bring said springs more closely together when their terminal coils are placed within the pockets between the strips E and t-he casing walls.

In assembling the structure, the -staples may be inserted before or after the end coils the pockets formed between the.

of the springs have been introduced into their respective pockets. If the staples` are inserted 1n advance, it will be necessary to compress slightly the ends of the terminal coils of each lspring which may then, b a slight` l e causedk turning movement of the spring, to pass between the staples F and the outer walls of the appropriate pocketfor such spring. Whenl the springs have been thus positioned, they will be securely retained against danger of displacement andof contact with each other.

Where the mattress is liable to be subjected to exceptionally rough treatment, I may, if desired, tiev or secure the end coils of the springs to the upper and lower walls of the casing. For example, cord ties or loops. They may be separate ties, as shownat or they can be merely parts of continuous cords extending along the surface of the casin and looped under the wire of the coils as si at y.

Since the specific embodiment therein disclosed is merely'illustrative of a single application of my invention, it will be understood that the scope of same should be determined by reference to the appended claims, said claims being construed as broadly as' possible, consistent with the state of the art. Having thusdescribed my invention, what I claim as new and desire to secure by Letters Patent is:

1. A mattress or like structure comprising rows of axially vertical coil springs, the springs of adjacent rows being staggered and springs, and strips of flexible material secured tothe wall of the casing by sinuous 'partially nested, a casing enclosing said to conne the springs disposed therebetween against movement 'longitudinally and transversely of said strips.

2. A mattress or like structure comprising a plurality of rows of coil springs, therows being arranged so that the springs of adjacent rows are staggered relative to each other, and so that the springs of one row nest between the springs of an adjacent row, a casing enclosing said rows of springs and including top and bottom tick portions, and means for holding the springs in position within said casing, comprising strips of fabric secured to the inner faces of the top and bottom tick portions respectively, and arranged to confine portions of the terminal coils of said springs between the respective tick portions and said strips, each of said strips being of a width sutlicient to overlie the nesting portions of the springs in two adjacent rows, and being secured to the respective tick portions along meandering lines extending between said rows so as to form alternate oppositely facing pockets or receiving and confining the nested portions of the terminal coils, said springs being thereby held against movement longitudinally and transversely of said strips. 3. A mattress or like structure comprising rows of axially vertical coil springs, the springs of adjacent rows being arranged in staggered relation to each other and partially nested, a casing enclosing said springs, strips of iexible material secured to the wall of the casing by divergent lines of stitching to form alternately arranged pockets facing in opposite directionsand adapted to receive the terminal coils of the springs of two adjacent rows, adjacent lines of said stitching serving to confine the springs disposed therebetween against movement longitudinally and transversely of said strips, and staples uniting said strips to said casing wall within the areas of the pockets and at a sufficient distance from the boundaries thereof to admit said coi-ls.
