IVIATTBESS OR THE LEE.

Application filed November 22, 1920. Serial No. 425,685.

To all whom it mug V concern:

Be it known that v mums A. llER- MANN, u citizen of the United States, residing at lllilv;nukee county of lililivsukee, and State of Wisconsin have invented new and usetul improvements in Mattresses or the like, of which the following is e specificsion.

This invention relates to mu' tresses, upholsterv cushions and other devices of a similar nature and is particularly directed to a, resilient cushion in which springs are interposed betv ."1 le ers of I :h cushion.

i-c-c'ts of this invention ore to provide at resident cushion or mattress in which the interposed res' ent moi-n ers are so secured to the upper and lower covers as to minimize weer ut the points of attachment and thereby produce structure; to so associate the springs and covers that occidental displacement of the springs is rendered impossible; and to so form the spring itself that it cooperates with the covers to definitely position the spring.

Other objects are to provide :1 resilient cushion or mattress Whose parts may be readily assembled and require a minimum number of operations; to provide e structure which may be economically produced; and to generally simplify the construction of resilient cushions.

Other objects are to provide resilient cushion in. which the springs are held out of contact with each other 1' with other metallic ports to thereby both minimize Wear and prevent noise; to so form the spring itself that each spring may be identical With all the other springs and toprovide s resilient cushion in which no additional treatment of the burlap or other covering is required in order to adopt such cover for association with the springs.

An embodiment of the invention is shown in the accompanying drawing, in which:

Figure 1 is a fragmentary sectional elevation of a mattress or resilient cushion embodying the invention.

Fig 2 is a plan view of the structure shown in Fig. 1 with a portion of the upper cover removed to more clearly illustrate the spring construction.

in the practice of this invention, it is con templuted employing some form of strong fabric, such as burlap, for the casing of the mattress or resilient cushion and to comblue with this burla spacing resilient means so formcdthst no treatment of the burlap is necesssry in order to effect the secure anchoring of the resilient means in position its upper and lower ends.

The upper cover 1 and the lower cover 2 may conveniently be of burlap or other strong fabric and preferably of such fabric as is provided with a course weave. The spacing springs ore-resilient means comprise helical springs 3 huv' upper and lower convolutions 4i. These u per and lower convolutions are each provided with a series of radially projecting enlargements 5, three of suchenlsrgenie being provided for such terminal convolution and equally spaced nbout the periphery thereof. enlargements con prise an elongated looo having a substantially rectangular shape and formed integral with the spring. The portions 8, which join the'rectongulor enlargements to the main portion of the convolution, are juxtaposed end are abruptly curved to form constricted portions 6 which are bordered on one side by the inner ecge of the rectsngle end on the other side by the convolution itself. In this manner, the restricted por tions 6 be relatively long andnsrroiv' do provide adequate room for any slight motion of the fabric engaged by these projections and prevents disengagement of the fabric therefrom. The ends of each terminal convolution are provided With rounded eyelets 7 which prevent such ends from cutting into the fabric or otherwise protruding therefrom.

l n assembling the elements of the mattress or resilient cushion, the Warp and Weft of the upper and lower coverings are slightly spread and one end of an enlargement 5 is inserted Within the opening thus formed and after such end has been projected through the opening to a convenient extent, the warp and Weft are then slipped past the other end thereby allowing the fabric to assume substantially its original formation and to close about the connecting portions 8. Thereafter the other enlargements ore correspondingly secured.

It is to be noted that all of the sprin s may be identical and that a very simp e manipulation of the fabric is required to definitely position the springs in place and that, due to the identical construction of springs, a mattress or cushion of any desired extent may be formed by positioning the proper number of springs between the upper and lower coverings.

It is to be understood that while this invention is particularly designed for mattresses, it is equally applicable to cushions, upholstery, and other similar articles, and that while the springs have been described and illustrated as of identical construction, it is within the scope of this invention to provide different forms of springs, and, if desired, different types of springs within the same structure.

It will thus be seen that a mattress or resilient cushion has been provided in which a minimum number of operations are necessary in assembling such device and in which wear is minimized as the fabric is neither clamped or gripped between metal members nor is it restricted and prevented from any movement relative to the terminal convolutions. It is to be noted that a slight shifting of the fabric is permitted as the mattress or resilient cushion assumes different positions in use, and that such shifting does not result in binding of the fabric as the fabric is at all times in contact only with smooth surfaces and rounded corners.

I claim:

1. A cushioning device comprising covers, springs interposed between said covers and comprising a main body portion provided with integral terminal convolutions bearing upon the inner sides of said covers, and means formed integral with said terminal convolutions to engage and positively retain said covers in contact with said terminal convolutions.

2. A resilient cushioning device comprising covers, helical springs interposed between said covers and spacing them apart, said springs having terminal convolutions formed integral with the main body portion thereof, and locking loops formed integral with said terminal convolutions and projecting from the said terminal convolutions and through said covers to definitely lock to said covers and position said springs with reference to said covers.

3. A resilient cushioning device compriscovers to resiliently space them apart, said i springs each comprising a main body portion provided with integral terminal convolutions, and substantially rectangular loops formed integrally with said terminal convolutions and projecting from said convolutions and extending through said covers, said leops passing through said covers and positioning said springs while permitting limited relative movement of said covers with respect to said end convolutions, whereby binding and wearing of said covers at the point of attachment to the springs is minimized.

5. A resilient cushioning device comprising fabric members, springs interposed between said fabric members, and having terminal convolutions in engagement with the inner faces of said fabric members to resilently space such members apart, substantially rectangular loops integrally joined to said terminal convolutions by curved connecting arms and extending through said fabric members and positioning a portion of said fabric members between said rectangular loops and said terminal convolutions, whereby said springs may be secured in position between said fabric members without cutting said fabric members and whereby wear of said fabric members is minimized.
