wmn FABRIC.

' Toall Be it known' that L'Joan L. Isaaos,

citizien .of the United; States, residing at Red in the connty pf Monmouth and State of New Jersey, have invented certain new useful" Improvements in: Wire Fabrics, of which-thefollowing is a specifi cation.

- This invention relates to wire fabrics, and' v moreparticularly, though not exclusively, to that class of fabrics employed for the bottoms of beds, couches, and the. like. The older form of woven wire fabrics, atone time extensively employed for such pur- '15' poses,.has latterly been largely displaced by -a. type of fabric made up of bent wire units connected in longitudinal and transverse rows; and, out of considerations of economy inrmanufacture, these bent wire units are commonly made uniform in res ect to size and contour, and are connecte in such a manner as to afford suflicien't flexibility to enable thefabric to-b'e folded for shipment and storage; 'and -tlie' re uiredresiliency is ,fiiseoured through oyment of rows of helical springsusually coated between the "upper and lower ends of the fabrics and the ,up er and I'OWBILCEOSS-bMSOf the frame to which the fabric is applied.

1 V Various of fabrics of this type have.heretoforebeen proposed; and among 'theprincipalc'objects and advantages attained by the article of the present inven- 1 tioflare, first,-.'to produce an improved fab- 3S ric in'which the cross-'hnks connecting the 9 adjacent lo tudinal strands are not a toslip out o lace, bnt are secured against 1 accidental ocaition through en agement "Rwith closed loops or eyes; secon to ,pro- Jfl 'duee' such a fabric in-which the units makthe longitudinal strands are so confnec as not to'be liable to accidental sep- -aration or relative-slip; and, third, to produce a fabric of an improved and attractive appearance and more staple character, and

one which shall be more compact than similar fabrics not known, and which will not i popen under thestrains of shi ment.

My invention will be rea ily understood when considered in connection with the accompan g drawings, in which I have illustrated t ee slightly differing s ecific forms in 'which the mvention may nd embodiine'nt and-in which,-

# Figures 1 and 2are plan and ed e views of a fragmentary portion of the fabric, in-

cluding'one of thefend-rails to whichthe fabricissecured through the usual row of helicals. Fi s3 and '4 are views similar to 1 an 2, respectively, illustrating another $1 htly differing form of the inven-.

igs. 5 and 6 are views similar to Figs. 1 and 2, respectively, illustrating still anotherslightly different form of the invention wherein the tension member of the unit is composed of a single strand of wire.

' The chief novelty of my invention resides. in the structural features and characteristics.

of the individual bent-wire units which,

when connected end to end, go to make up the several longitudinal strands of the fabric. In accordance with my invention each of these units comprises a longitudinal tension member, which may be of either a singleor double length of wire, bent to form having a central loop or eyei 'a apted for direct engagement with' the hookof the next adjacent unit in the same longitudinal strand and, on either side of the tension member, havin laterally projecting closed loops or eyes t at are adapted for e agement with the hooks of the usual cross inks which connect laterally adjacent strands.

Referring to the drawings, 10 designates oneofthe end or cross-bars (herein shown as an angle-bar) of an ordinary bed frame, the horizontal flange of which is apertured as shown at 11 for the reception of the end hooks of the usual series of helical sprin 12 throu h which the upper and lower end: of the' fa bric are commonly united with the upper and lower cross bars of the frame, which furnish mainly the desired resiliency and elasticity. The fabric itself, in which the novel features of the present invention more particularly reside, 1s made up of a series of bent wire units arranged in lon tudinal and transverse rows,-.the units in t e same longitudinal rows bein directly intersite end hooked to form the longituinal strands of a the fabric, and the latter being connected at intervals by cross links. Referring first to the form of the invention shown in Figs 1 and 2, each of these units is formed from a single length of w1re so bent asto present a straight two-ply tension .mmber 13 bent.

engaged by either the hoo 14 of'a'n adjacent v mm; 111 the same strand-or by the inner hookself; formin thence the wire, cross ng the tension member 19, is similarly doubled or looped upon itself, a

t f or slip of t e cross links 17, and, similarly,

' the closed central loops 15 prevent any ap preciable' slip of adjacent units lengthwise 15 of each other. The clover-leaf form ofhead of'the' unit also gives to the fabric as a whole aneat and'attractive appearance.

' The form of the invention shown in=Fi ebsnde and already described chieflyin the 0 m of they central loop 18 at the closedend of:

the unit, this being an open -'or.-inver ted U- shaped formof loop" having approximately parallel sides merging into the lateral loops or eyes, .insteadjofthe crossed sides of the loops of Figs; 1 and 2.

i: In Figsr5 and 6 I'have shown-a f orrn of I the invention. in which; the form and ar-' rangement of the threeloops or eyes at the T36 'closedtend of the uiiitis the same as that shown in Figs. Land 2, although the bending of the wire to form these loopsiis effected in a somewhat difi'erent manner, and the l0ngitudinal tension .member vconsists of but a single length '19 of wire. Informing the.

loops, in this'form' of the invention, the wire I book 20,; is continued upwardlyfa'nd then .bentr back across itself to form the-Icentral 0 a tinued toone side and bent-back across itone of thelateral loops 16 forming the opposite lateral loop 16 and, l V :finally, the-end of the wire is twisted one or more times around; the longitudinal memm, ber 19, 'asshowgat 21, care beingtaken that bottom or :under side of the fabric to pretearing the n 1attress-. The form of the in-- vention' last described, while not possessing thesame degree of tensional strength as that afi'orded by the; forms shown in,v Figs. 1.

. ,such as to render the unit' elastic both lonwhen the fabric is assembled, the closed loops 3 and 4 difilers from that shown in '1 I l9, bent ,.inwardly atone end to provide a longitudinallOo 515. The Wire is thencon- I v tially as. described. the; end'-' ofth'wire twist shall lie on the -,I.

* vent the possibility of itsicatc'hing-in'and' strong formany purposes, andofl'erszan advangage in respect to economy of material use l Itiwill' be observed that the disposition of the 'Wire forming" the central and lateral loops atthe' headof eaclrunit is, in all of the several forms of the invention shown,

gitudinally and transversely; which characteristic contributes not only to the wearing qualities ofthe article but alSoto-itsinteg- 1 'rity and durability, since any slack which rmig'ht result in the disconnecting of the interhooked parts is automaticallytaken-up by the 'elasticityoffi theunit's as'soon'as any strain on thefabri'e is inter-mitted.

In all of the sever'al'j-"fornis shown the structureand mode oflconnecting l'the units and cross links is suclrl'as to render-the fabrie not'liable to distortion-hrdisplacement 01"; separation of its constituent parts under the strains of-servic'e' or shi ment; each unit has three distinetdoopsfor eyes, each of which engages but a single hook; thus mal ing the fabric'easy toassembl'e; the-"design f or pattern is a compact and attractive one;
