BAYER, or nanosna, WISCONSIN, assumes no sinuous COMPANY, .01 moan, wlsoonsm, a coaroaarron or DELAWARE MATTRESS AND LIKE STRUCTURE Application filed June 18,

My presentv invention, while susceptible of wider application, is especially apphcable to that class of mattresses or cushions the resiliency of which is secured by means of coil 7 springs inclosed within a casing and ordinarily'surrounded by a pad secured to the casing walls. In mattresses and like structures of this character, it is highly important that the coil springs shall be united together 0 in such manner that while the greatest flexibility is obtained, the danger of the springs chafing together and becoming distorted shall be avoided. The invention 1s directed primarily to the provision of improvedmeans for holdin the springs in proper and most effective re ative position, and the invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of the specification.

Figure 1 is a plan View showing a group of springs embodying my invention. Figure 2 is a view in vertical section through a mattress or cushion embodying the invention. Figure 3 is a View in vertical section on line 33 of Fig. 4. Figure 4 is a detail plan view 'showingthe improved manner of connecting adjacent coil springs together. Figure 5 is a view in cross section on line 55 of 4. Figure 6 is a detail view of a metal fastener used in carrying out my invention.

The coil springs A will be arranged in rows and are shown as inclosed within a casing B of ticking or like material that may be surrounded by a pad 0', this pad being united to the casing as by tuftingcords D, corner threads D, etc., in a manner well understood by those familiar with this class of devices.

The terminal coils of each of the springs A isformed with offset portions a arranged at diametrically opposite points, as clearly shown in Fig. 1 of the drawings. These terminal coils of the springs A, when placed in juxtaposition, are united together by flexible connections E of fibrous material extending between said springs. Preferably, the connections E consist of spiral strands e and e of heav cord, the end portions of these strands eing connected to the terminal coils 1824'. Serial N0. 719,726.

of the. springs A by means of metal fasteners Each of these fasteners F is formed with a plurality of arms f, f and F, the arm being, by preference, of somewhat greater width than the arms f and F. In fastening the terminal coils of adjacent springs together, the strands ofthe flexible connections will be laid across the offset portions (2 of the terminal coils of the springs'A. The metal fasteners F will be placed about the strands of the flexible connections in such manner that the broad arm f of the fastener F shall extend. between the ends of the strands e and e andupon the inside of the offset portion a of the terminal coil,while the arms fand f of the fastener F extend upon the inside of the coil preferably adjacent the juncture of-the inclined portion. a of the offset a with the body of the terminal coil of the spring The arms 7, f and f of the fastener F will be bent around the inclined portions a of the offset a, as shown in Figs. 3 and 4, and the arm f of the fastener F will be bent inwardly as shown, the fastener F thus rigidly uniting the flexible strandsto the terminal coil of the spring and in such manner that all danger of the pulling of the strands from the fastener is avoided. Inasmuch as the crown ofthe fastener F extends across the offset portion a of'th'e terminal coil, while the arms of the 'fastenerlare rigidly clamped or clenched in the position shown, all danger of any vertical or circumferential movement of the fastener is avoided. At the same time, however, the strands e and e afford a flexible connection between the ter-.

formity of. elasticity and without danger of the springs chafing together orbecom'i'ng in terlocked. M I

It will be observedthat the strandsfarerelatively thick and stout, with th ei r 'iiitermediate unclamped portions relatively "short,

us plication of my invention, it will so thatthey operate not only as ties for preventing separation of the coils, but also as struts for preventing the springs 'from approaching each other close enough for the ofisets or clips to make contact with each other.

The individual action of each spring is thus preserved to the maximum extent possible, while at the same time the" spring asm sembl is sufliciently rigid to keepthe con-' stru'ction of the desired shape and size during assembly and also in service.

Since the specific embodiment herein disclosed is merely illustrative of a. single apbe' under stood; 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 thus described my invention, what I claim as new and desire to secure by Letters Patent is I 1. A5 mattress or like structure comprisin a plurality of rows of coil springs arrange I in juxtaposition with their-axes parallel, relatively short stout connections of flexible fibrous material extending between the end clips, the armed members,

serve res ectively to secure said connections of the respective end coils, and the end por t ons of said double connections being respectiliirely secured to said arm portions by said c ps.

4. A mattress or like structure comprisin a plurality of rows of coil springs arrange in juxtaposition with their axes parallel, double connections of flexible fibrous material extending between the end coils of adjacent springs, and metallic fastener clips rigidly united to said springs and rigidly securing said connections to the respective springs, said end coils having ofiset portions including, in effect, a pair of arms respectively extending angularly from the adjacent portions of the respective end coils, and the end portions of said double connections being respectively secured to said armportions by said latter comprising,.' efiect, threetwo ofthe arms of which to said 0 set end coil arms, and the third arm of said clip serving to biteinto said connections-to prevent slippage thereof with respect to the springs.
