Application filed April 2,

This invention relates to mattresses or cushions, and its principal object is to provide a simple, durable and comparatively inexpensive s ring construction for mattressesand cus ions which can be constructed and assembled with great rapidity and at considerably less cost than the ordinary spring constructions for mattresses and cushions.

Another object is to minimize the amount of material employed in' the connecting means between the coiled springs and thecovering material to which the sprin s are attached. Another object is to provi e improved non-metallic means whereby the end coils or convolutions of the springs may be quickly and readily attached to the covering material for the springs. Another object is to provide a plura 'ty of layers of fabric between the mlddle coils and end coils of the the minimum material required the springs to the covering material, where b a more durable mattress or cushion is obtained.

With-these and other objects and advantages in view, this invention consists in the several novel features of construction, arment and combination of parts hereina or fully set forth and claimed.

The invention is clearl illustrated in the drawing accompanying whichbetween the retainer strips and covering ma- Figure 1- is a fragmental vertical cross section taken through a mattress or cushion spring construction, and illustrating a sim le embodiment of the present invention; 1g. 2 is a perspective view of a fragment of one of the covers of thesp tion, and showing the spring retaining strips securedthereto; a

Fig. 5 is a fragmental plan of the mattress r cushion spring construction.

Referring to said drawin which illustrates a single embodiment o the present invention applied to a mattress or cushion, the

aracters 6, 6 designate two pieces of coverin material which enclose the springs, an said pieces may be of the desired size and shape to form a spring conreference c or connecting stitches are spaced a t is specification in P 'open corners into w 'the springs are inserted, and the four closed construe- 1928.

preferred to use coiled springs of that type in which the end coils are of a greater diameter than the intermediate ones, such a t pe of spring being I strips 0 fabric material ,8 are stitched to the inner sides of the covering material 6 by rows of stitches 9 that run transversely of the'strips through which they pass and run parallel with and approximately midway between the other strips.

There are two layers of strips, the strips of one layer extending parallel with each other and running in one direction, and the strips of the other layer'extending parallel with each other and running in a direction at right angles tioned layer. spaced apart The strips of each la or are (center to center) a istance to the strips of the first menshown in the drawing. he

en coils of the springs, and the rows of art a distance a proximately equal to or s ightly greater t an the diameter of the end coils of the springs.

The covering material and arts of the strips bounded by the adjacent rows of stitches, form square pockets havin hich the end coils 10 0 portions of the sides of said pockets confine the end coils of thesprings against displacement with respect to the covering material and locate the springs in proper position relative to each other thro bout the extent of the spring construction. attaching the coiled springs to end coil of a sprin is inserted between two intersecting parts 0 the strips and the covering material and turned upon its axis until the whole or-greater part of-the end coil is brou ht between the strips and covering materia Both ends of the springs are attached to the covering material in the same manner,

intersecting the covering material,'the Q after which the sides and endsof the spring construction are closed in the usual manner and the usual cotton, felt, or the like, laced around it and covered with the usual outer tion pertains.

It is apparent that a much simpler, neater and more efiicient spring construction is obtained with the use of the intersecting strips of material attached to the covering material as described, than any construction where layers of stitched together material are used in which slits are formed in one of the layers through which the end coils of the sprmgs are inserted.

Furthermore, the intersectin portions of the strips provide two layers 0 material between the midille coils and end coils of the springs, thereby greatly increasing the efficiency of the mattress or cushion. When the spring is compressed, in use, the middle coils are pressed against the intersecting coils of the coiled springs is facilitated, be-

strips, and because of the double thickness of material between the middle coils and end coils, the life of the mattress or cushion is lengthened. This is particularly noticeable. .in mattress or cushions having springs of which the diameter of the coils decreases toward the middle of the spring. The intersectin provi es three layers which fully rcsistthe tendency for the springs to push through the material. Furthermore, since the strips are whole throughout their extent, the tendency to fray out at slit places is eliminated, and, conse uently, they last longer than a slit layer 0 material. 1

Furthermore, the machinery for making the slits, and the time and labor required in making them is eliminated, and, consequently, the cost of production is reduced considerably. Furthermore, a-saving is bad:

because the strips may be formed of material that would otherwise. be waste material. Also, by reason of the open corner construction of the pockets, the insertion of the end cause the workman is able to observe the end coil as it is turned around in the pocket.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention. I desire, therefore, not to limit myself to the exact-form of the construction shown and described, but intend, in the following claims, to point out all of the invention disclosed herein.

I claim as new, and desire to Letters Patent:

1. In a spring-construction, the combination of a fabric covering, intersecting fabric strips lying in planes substantially parallel with and secured to said fabric covering by rows of fastening means running crosswise through each strip at places between the intersections of the strips, whereby open cornered pockets are formed and coiled springs having open-ended coils confined in the pockets between intersecting strips and the fabric covering with the ma'or portion of said end coils covered by said intersecting secure by strips, together with the covering,

tion of a fabric covering, intersecting fabric strips lying in planes substantially parallel with and stitched to said fabric covering by rows of stitches running crosswise through each strip at places between the intersections of the strips, whereby open cornered pockets are formed between the intersecting strips andcovering material, and coiled springs, having open end coils which are insertable into the pockets through the open corners thereof and confined therein with the major portion of said end coils covered by said intersecting strips, the extent of said corner openings being less than that of the end coils, whereby displacement of the end coils through the corner openings is prevented.

3. In a spring construction, the combination of a fabric covering, intersecting fabric strips lying in planes substantially parallel with and stitched to said covering by rows of stitches running. cross wise through each strip at places between the intersections of the jecting from said strips, the end coils of the springs being held in the pockets between the intersecting strips and covering with the major portion of said end coils covered by said intersecting strips, the extent of said corner openings being less than that of the end coils, whereby displacement of the end coils through the corner openings is pre-.

vented.

4. In a spring construction, the combination of a fabric covering, a layer of spaced fabric strips extending along the covering 1n one direction, and a layer of spaced strips laid crosswise of the strips of the first layer and extending along the covering, rows of stitches extending approximately midway between the parallel strips and passing through the strips which intersect them, whereby open cornered pockets are formed between the intersecting strips and covering, and coiled springs having their end coils held in said pockets with the major portion of said end coils covered by said intersecting strips, the extent of said corner openings being less than that of the end coils, whereby displacement of the end coils through the corner openings is prevented.

5. In a spring construction, the combination of two spaced fabric coverings, each having intersecting fabric strips lying in planes substantially parallel therewith on the face opposed to the other covering, said strips being stitched to their associated covering by stitches running approximately midway beciated covering with the major portion of tween the perallel strips and through the said end coils covered by said intersecting strips which lntersect them and thereby form strips, the extent of said corner openings 10 open cornered pockets, and coiled springs exbeing less than that of the end coils, whereby 5 tending between said coverings and having displacement of the end coils through the their end coils held in the pockets between the corner openings is prevented.
