WIRE-MATTRESS FABRIC.

To all whom, 'it may concern Be it known that I, JOHN L. TANDY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in lVire-hlattress Fabric, of which the following is a specification. This invention relates to wire fabrics for use principally as mattresses for beds, couches and the like, and has for its object to produce a simple, strong, durable and cheap mattress having great resilience and no appreciable tendency to sag at any other point than that where weight is imposed upon it.

A further object is to produce a wire fabric mattressadapted, where used on a couch having a folding part, to fold with such part so sharply that it makes a practically perfect corner or edge.

A still further object is to produce a mattress which when folded downward may be compressed as by a person seated upon it, wit-hout receiving any injury whatever and which when relieved of the weight of such person, immediately returns to normal con dition.

Vith these objects in view the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which- Figure l is a plan view of an incomplete spring mattress embodying my invention. Fig. Q is a similar View of the preferred construction for standard size beds. Fig. 3 is a similar view showing a second modified form. F ig. 4: is a similar view of a third modified form. Fig. 5 is an enlarged perspective view showing a part of the wire fabric common to all of the forms.

In the said drawings, l indicates the usual or any preferred type of rectangular mattress frame, Q a series of retractile springs connected to the end rails of the frame and 3 a series of rings linked to the inner ends of said springs.

The endmost rings, 3, are united by parallel stays or connections, preferably in the form of chains consisting of series of interlocked links 4: and rings 5, and in Figs. Q, 3 and 4tthe central springs 2 are likewise united by a similar stay or connection, pref- Speccation of Letters Patent.

erably composed of links t and 5, Fig. 2 also showing two other similar stays connecting alined springs Q, and arranged by preference, centrally between the chains adjacent to the side rails of the frame and the chain arranged centrally between said chains. In Figs. 3 aud t appear cross` chains (5 composed of similar but `uunumbered links and rings.

7 indicates parallel wires arranged longi tudinally of the frame and connecting together all of the alined springs 2 not connected by the said stays, that is to say, the said longitudinal wires 7 connect the rings 8 of such springs though it is obvious that such rings are not; indispensable as the hookends of wires 7 could be iuterlocked directly with the corresponding ends of springs f2.

S indicates links arranged to form parallel strands, most of which in Figs. 1 and 2, extend diagonally from one longitudinal stay to the adjacent longitiulinal stay, the rcmaining strands extending from the side stays to rings 3 of the springs 2, as shown clearly. Each of the links S is formed at its ends with elongated eyes 9 so as to be capable of some endwise mo-ven'lent independently of lateral movement of the wires 7 extending through such eyes, and in this connection it will be noticed that the ends of each link lap the adjacent ends of the contiguous links at the sides of the latter which forni acute angles with the wires which the intervening link connects, that is to say, the links are so disposed with respect to each other that, when the fabric is stretched tightly as it is norn'lally, their overlapped ends prevent each other from swinging apart as indicated by the adjacent arrows, (Fig. l), it being furthermore apparent that, as said links can not swing in the direct-ion indicated by their respective arrows referred to, they necessarily prevent each other from swinging in the opposite directions. As a result of this construction the imposition of weight on the fabric does not result in any sliding movement of the links on wires 7, though they do have a slight pivotal movement due to the tendency of the strands to seek a position at right angles to wires 7 under the endwise pull of the chains in opposite directions. lt will furthermore be apparent that if weight be directly imposed upon a number of the wires 7, such wires will, of course, yield downward and move apart, but because of the similar series of parallel strands extending obliquely across the remaining Wires and connected at their ends to said first-named stay and the other side stay, the two series of strands extending at opposite angles from the rst-named stay so as to conjointly form a plurality of V-shaped strands connected at their apices to the first-named stay and at their opposite ends to the side stays; each strand consisting of a plurality of parallel obliquelyarranged links and embodying end links connected at their outer ends t0 the irst-named stay and the outer stay and provided with eyes at their inner ends receiving the adjacent parallel wires, and one or more intermediate links having eyes receiving adjacent Wires of the series between said stays, the eyes of each intermediate link lapping the adjacent eyes of contiguous links at the sides of the latter which form acute angles with the Wires of said series which the intervening link connects.

6. In a Wire fabric, three parallel stays, one or more wires between and substantially paralleling the intermediate stay and each outer stay, and converging series of connections, each series being composed of separate strands extending from the two outer stays to the third or intermediate stay and attached at their opposite ends to said outer and intermediate stays; each of the strands between adjacent stays consisting of a plurality of substantially parallel links which overlap at their adjacent ends at the point or points where said strands cross said wire or wires between said Stays and pivotally engage said wire or wires at said overlapped ends.

In testimony whereof I aliix my signature, in the presence of two witnesses.
