METALLIC FABRIC.

Specification of Letters Patent.

Patented Oct. 12, 1915.

T all whom it may concern.

Be it known that I, IVILLIAM B. Ammusox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metallic Fabrics, of which the following is a specification.

My invention relates to improvements in metallic fabrics and has particular reference to a novel and advantageous elastic fabric, especially well adapted for use in the construction of spring mattresses, bed bottoms, and the like, in which longitudinally extending metal ribbons, or thin metal slats are interwoven with transversely disposed, similar slats, which are uniformly placed, at proper intervals, along the longitudinal extent thereof and secured at their terminals to extra wide, longitudinal slats. The substantiallyflat elastic fabric thus produced is suspended in a relatively rigid frame by coil springs attached to each end of the longitudinal members that are spaced apart at points of attachment to said frame.

One of the especial objects of my invention is to provide in a bed bottom structure, one or more transverse slats, arranged, with reference to the longitudinal slats, so as to prevent material, relative, axial or endwise sliding movement of the longitudinal slats, and to prevent spreading or relative transverse movement thereof, whereby to effect a yielding, noiseless structure, as a whole.

An important feature of my invention is the provision of longitudinal side terminal slats that are heavier and wider than the intermediate slats, and to which are riveted, or otherwise secured the ends of the transverse slats, and to attach these wider terminal slats to the frame by means of two helical springs at each end, said springs being separated further at their ends that are connected to the frame. than at their ends that are connected to the slats, whereby to more surely return said terminal slats, and attached transverse slats, to their respective normal positions, and to provide a more substantial marginal side edge for the spring structure.

Other, further and more specific objects of my invention will become readily apparent to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein- Figure 1 is a plan view of my spring bed bottom structure and Fig. 2 is an enlarged detail of a means to prevent relative displacement of the respective members at selected points of intersection.

In both views the same reference charterminal side members 16 and 17.are each connected to the frame end members 10 and 11, as by springs 18 and 19. It will be noted that these springs have their ends relatively close together at the points where they are connected to the side slat members, and relatively far apart, as at 20 and 21, where they are connected to the frame end members 10 and 11. Interwoven with the longitudinal members 14 are transverse members 22 22'22". These transverse members are each connected, at their terminals to the side slat members 16 and 17, as at 23. To prevent relative longitudinal movement of the'members 14 I prefer to slot them near their longitudinal center, as at-2-l, and to pass one of the transverse members 22 through the slots, a portion of the member 14 at the slot being displaced for this purpose. I also slot the two transverse members 22', one on each side of the central, transverse member 22 to prevent the lateral, relative displacement of the members 14 so that they may not move apart, to any appreciable extent, at the points of their engagement with the transverse member 22, as when any unusual pressure is brought to bear upon any isolated area of the fabric. When this is done the side members 16 and 17 will move inwardly, to some extent, against the yielding resistance of the springs 18 and 19 but by reason of the separation of the springs 18 and 19, at the points of attachment to the end members 10 and 11 they serve to return the displaced terminal side members 16 and 17, to their original positions, when the pressureis removed, hus preserving a uniformly fiat even surface throughout the entire fabric and by the c011- stant effort and effect of the springs, 18 and 19,- to maintain this condition, undesirable sagging 0r buckling of any area of the mattress support is. prevented. I prefer to thus tie the longitudinal members together by slats, one on each side of said central members by slotting the respective members but other means than that shown may be employed for carrying out the object and intent of my invention, whereby the longitudinal members are prevented from moving endwise, or sidewise near the central zone of the structure. 1

Having described my invention, What I claim with a view and desire to secure by Letters Patent is:

A device of the character described comprising a resilient fabric, composed of uniformly separated, longitudinal slats and similar transverse slats interwoven together to provide a fiat surface; a supporting frame; springs connecting said longitudinal members at each individual end to said frame; means to prevent relative, axial movement of said longitudinal members but to permit relative transverse movement thereof at or near the longitudinal central zone of the structure, and means positioned atboth sides of the central zone lengthwise of the device to prevent transverse movement of said longitudinal members but to permit axial movement thereof.

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses.
