MATTRESS FABRIC.

Specification of Letters Patent.

Patented Mar. 29, 1921.

- Application filed. July 23, 1920. Serial No. 398,333.

To all whom it may concern:

Be it known that I, OTTO J. GAsAU, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Mattress Fabrics, of which the following is a specification.

The invention pertains more particularly to mattress fabrics or spring bed bottoms, and it consists in the novel features and structure hereinafter described, and particularly pointed out in the claims.

The mattress of my invention comprises a novel mattress fabric formed of transverse sections suitably hooked together and preferably secured to usual head and foot bars by helicals and to side members by links. One object of this inventionis to facilitate the manufacture and assembling of the sections of a' wire mattress fabric and to provide sections which, when assembled, will create a diamond effect throughout the fabric, the openings or meshes in, the fabric being of true diamond outline and the de-- fining wires in the assembled fabric being eX- tended on substantially continuous straight crossing lines diagonally of the mattress.

1 form each transverse section of the mattress, by preference, from one integral rod of wire bent zigzag to define between eac.. two adjacent members thereof the outline of one-half of a diamond figure, and at the inner apex or junction point between each two adjacent members I form a doublestrand hook, while at the outer apex point between each two adjacent members I form an eye. The eyes of one transverse section of the mattress fabric are adapted to be caught upon the hooks 0f the next adj acent section of the mattress fabric and in this way the mattress may be built up from the transverse sections with the least possible delay. The formation of the transverse sections of the mattress is such that said sec tions may be readily and durably manufactured and, when assembled, present a spring structure of uniform appearance and one in whichstrains are equalized throughout the mattress in a manner tending to render the mattress mechanically and otherwise of ad vantageous character. 7

The invention will be fully understood from the detailed description hereinafter Fig. 4 is an enlarged view, partly broken away, showing the double-hook end on one section of the mattress and illustrating by dotted linesthe connection of said hook with an eye on an adjacent section of the mattress and the effect on the double-hook of a tension placed on the spring mattress, such tension acting to draw the adjacent side members of the hookin a direction toward each other, as the dotted lines indicate;

Fig. 5 is a top view, corresponding with Fig. 1, illustrating a modified construction ofdthe transverse sections of the mattress; an

Fig. 6 is a top view, partly broken away, of one of the transverse sections of the mattress shown in Fig. 5.

The wire fabric is connected at its ends by helicals 10 to end rails 11 and at its sides by links 12 with side members of suitable type 13 whose ends are connected by helicals 14 with the aforesaid end rails 11.

My invention pertains more particularly to the wire fabric, and this fabric will be connected with the usual types of frames em ployed by manufacturers of wire mattresses, these frames, as is well known, comprising rigid side bars and rigid end bars connected therewith and usually arranged on a

higher tions

15, 16, all of the sections 15 being alike and all of the sections 16 being alike, and the

sections

15, 16 being alike with the exception that at their outer side ends the wires of the. sections 16 are formed into eyes 17 to receive the side ends of the sections 15 and the inner ends of the'links 12 by which the fabric may be secured to the side or edge members 13.

Each section 15 is formed from a single rod of wire bent into zigzag form to define equal members sharply defining the shape of one-half of a diamond figure,'said halfdiamond shapes alternately extending inwardly, as at 18, and outwardly, as at 19, and said

shapes

18, 19 being coequal and presenting straight though diverging equal edges or

members

20, 20. At the outer apex ends of the mesh shapes 18,the wire of each section 15 is bent to form eyes 21 which are preferably closed by twisting the wire at what would otherwise be the open side.

i of the eye, this closing of the eyes 21 serving to strengthen the fabric without adding material expense thereto; and at the inner apex ends of each shape 19 of the sections 15 l bend the adjacent portions of the wire members 20 into a double-hook 22 which has parallel closely related longitudinal sides 23 of such length as to admit, under strains, of a slight yielding of the same toward and from each other, as indicated by the dotted and full lines in Fig. 4. The side members 20 of the shapes 19 are brought into close relation to each other and then bent longitudinally to form the hooks 22, said hooks when thus formed with the said side members 20 brought nearly together serving as very durable connecting means for the adjacent transverse section 16 of the fabric without destroying the true diamond effect I seek to maintain throughout the entire extent of the fabric. The wire of each section 15 at its side ends is formed into a hook 24 to engage the eyes 17 at the ends of the next adjacent fabric section 16. Each transverse fabric section 15 is thus of zigzag outline defining equal half-diamond spaces between the adjacent zigzag members thereof and each of said spaces at its outer apex end is formed with an eye 21 and at its inner end with the double-hook 22, the eyes 21 being preferably closed by the twisting of the wire, as shown at the upper end of Fig. 1, and said hooks being preferably formed of closely related parallel side members which are, by preference, slightly separated from each other.

The transverse sections 16 correspond substantially throughout with the sections 15,

with the exception that the zigzag portions of the sections 16 are reversed from those of the transverse sections 15 so that in matching the spaces of th sections 15, .16,

true diamond-shaped meshes are created. The outer apex ends of the zigzag members of the sections 16 are formed with eyes 21 1 corresponding with the eyes 21 of the sections 15, and at their inner apex ends the members of the sections 16 are formed with the double-hooks 22 corresponding with the double-hooks 22 of the members of the sections 15. The eyes 21 of the members of the section 16 are engaged upon the hooks 22 of the members of the adjacent section 15, and the double-hooks 22 of each section 16 are engaged by the eyes 21 of the next adjacent transverse section 15, as will be clearly understood on reference to Fig. 1. The only difference between the

sections

15, 16, with the exception of their reverse order, is that at its ends the section 15 is formed with hooks 2t and the section 16 is formed at its ends with eyesl? to engage said hooks 24: and also receive the inner ends of the links 12. The

sections

15, 16 are therefore substantially alike in all essential respects, and in the finished fabric said sections are arranged in reversed order so that the zigzag spaces of the section 15 and the zigzag spaces of the section 16 may open into one another and form true diamond mesh outlines. The zigzag members of the

sections

15, 16 are at equal angles, and hence when all of the

sections

15, 16 have been. connected together to form the mattress or spring fabric, said members extend along substantially continuous crossing diagonal lines, whereby strains exerted on the fabric are distributed along said diagonal lines, which are substantially unbroken or continuous throughout the fabric. The eyes 21 extend outwardly beyond the apexes of the zigzag shapes of the sections'15, 16 and are as small as may be consistent with the ready assembling of the parts of the fabric, and the hooks 22 extend inwardly at the apex points of the

sections

15, 16 alternating with the planes of said eyes and have their sides brought as close together as may consistently be done so as to' increase the strength and resisting qualities of the fabric and preserve the diagonal formation of the lines defining the diamond-shaped meshes of the fabric. The side members 23 of the hooks 22 are preferablyslightly separated so that in the event of strains on the fabric, said sides may, at their inner ends, yield with, V

the sides of the zigzag bends of the sections, thereby relieving the fabric of a rigidity it might otherwise have.

Figs. 5 and 6 illustrate a modification of manner shown in Figs. 1 and 2. In other respects the construction shown in Figs. 5 and 6 is the same as that presented in Figs.

i and 2, and therefore to avoid needless explanation I number Figs. 5 and 6 with the same numbering employed on Figs. 1 and 2, with the exception that the eyes numbered 21 in Figs. 1 and 2 are, in Figs. 5 and 6, numbered 30. The sections of the fabric shown in Figs. 5 and 6 define the same diamond outlines presented in Fig. l and The fabric composed of the sections 1 5,

16 is of particular advantage in that said sections form independent elongated units and may be easily assembled to form a fab.- ric of not only ornamental configuration, but one possessing substantially continuous crossing diagonal lines capable of resisting strains and not liable to unduesagging. regard it as particularly important that the wire members of the assembledv units extend on substantially continuous diagonal crossing lines creating the diamond-shaped meshes and lines of resistance extending diagonally of the fabric in crossing directions and being substantially unbroken, so that the lines of resistance are substantially directly through the zigzag side members of the portions of the respective units or sections of the fabric.
