BED-SPRING.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed. February 10, 1919. Serial No. 275,986.

To all whom t may concer/n.'

Be it known that we, SAMUEL lVnissMAN and RALPH l/VnisMAN, citizens' of the United States of America, residing at Detroit, in the county of layne and State of Michigan, have invented certain new and useful Improvements in Bed-Springs, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention aims to provide a novel Y i spring.

' Our invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing ,wherein- Figure l is a plan elevation of a mattress spring, partly broken away, showing the improvement in connection therewith;

. Fig. 2 is a similar view of another type of spring, provided with the improvement;

Fig. 3 is a perspective view of a portion VVof the spring shown in Fig. l;

Fig, 4 is a perspective view of a portion of the spring shown in Fig. 2, and

Fig. 5 is a plan of a plurality of spiral springs connected by cables in accordance with our invention. f

In Figs. l and 2 we have shown a spring frame composed of side rails 1 having the ends thereof connected by heads 2, said y spring frame being of a conventional form.

In Fig. 1 the heads 2 of the frame are connected by av plurality of longitudinal parallel members 3, said members being in the form of flat resilient strips having the ends thereof apertured and connectedto the heads 2 by coiled retractile springs 4:. The members 3 being comparatively flat afford a substantial body for the spring and to mainber relative to others, and afford a better body for the spring are spaced parallel transverse members 5 in the form of tubular or hollow spirally wound or woven flexible cables which have the ends thereof conlioiected to the outermost longitudinal mem- All of the longitudinal members 3 are provided with parallel slits 6 and the material between the slits is depressed to provide straps 7, said straps coperating with themarginal edges of the longitudinal members 3 in forming transverse eyes to receive the transverse flexible cable 5, thus allowing the greater part of each longitudinal member, at the eyes, to bear upon the transverse members and provide a connection suclras shown in Fig. 3.

In Fig. 2 of the drawing,`the longitudinal members are each made of wire oblong links 8 having loop and hook connected endsand in this instance the transverse members l() extend through the hook ends 9 of the links 8 and coperate in supporting the longitudinal members, the outermost of which are similar to the longitudinal members shown in'Fig. l.

It is also possible to use tubular-or holn low cables for connecting the confronting or adjacent convolutions of spiral springs l2 entering into the construction of mattress springs, cushion or somewhat similar structures, said cables having a degree of flexibility that contributes to the yieldability of the spring body, and from a manufacturing standpoint materiallyreducing the cost of a spring bypermitting of the same being expeditiously .and economically made.

Vhile kin the drawings there are illustrated the preferred embodiments of our invention, it is to be understood that the structuralV elements are susceptible to such changes, in size, shape and manner of assemblage, as fall within the scope of the appended claim.

What werclaim is In a mattress spring, the combination of a frame, longitudinal flat members connecting the ends of .said frame and having the upper faces thereof devoid of protuberances and disposed in a common plane, ysaid members having parallel slits therein with the matesoy rizil between said slits depressed to -provide In testimony whereof We affix our signa` eyes at the lower faces of said members, and tures in presence of two Witnesses.

cables having the ends thereoil connected to the outermost longitudinalV members and eX- tending through the eyes of said members so that said members may rest on said cables and relieve the slitted material of strains incident to a body on the spring.
