7*IHRE FABRIC.

Application led September 26, 1921. Serial No. 503,209.

To all whom 'it may concern:

Be it known 'that I, Hanni' M. YOUNG, a citizen ofV the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improve ment in Wire Fabrics, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates generally to wire fabrics and, more particularly. to a certain new and useful improvement 1n wire :tabrics oflthe knit-ted type especially adapted :tor use in the production of spring-mattresses for beds and the like, the principal object of my present invention being to provide a single wire knitted fabric whose construction is simple and inexpensive and which will minimize sagging or `distortion under` With the above and other objects in view, my present invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and afterwards pointed out in the claims.

In the accompanying drawing,

Figure l is a plan'view of a spring-inattress embodying' a section ot knitted wire fabric constructed in accordance with my invention; and

Figure 2 is a longitudinal sectional view of the mattress and' fabric taken approximately on the line 22, Figure 1.

:ReferringT now more in detail to the said drawing, which illustrates a practi 'al cmbodiment. ot my invention and in which like reference characters refer to like parts throughout tlie several views, A designates the single wire. or strand o'l the knitted portion of the structure, whose terminals B and C are relatively fixed, and which is fabricated as by knittinw to form an approximatetxv square mesh oody comprisingA loops D in spaced parallel rows extending in one direction or longitudinally of the fabric, and loopspacing strands or laterals E extending at a right angle to the loops D, whereby each inside mesh of the fabric, that is to say, each" of the meshes of the fabric except at the longitudinal and lateral sides thereof, comprises a pair of the loops D and a pair of the spacing` strands E.

Each so-called inside loop D comprises integrally a relatively sharp bight l, e, pair oit' suitably elongated legs or longitudinals 2-2 extending in approximately straight lines Afrom the bight l, and oppositely disposed turns or bends B--l at the ends ot' each leg or longitudinal 2 opposite the big-ht l, each intermediate loop ot' a row, that is to say, cach loop ot' a row except the end loops of the row, havingengagement at its bight with the bends of the next adjacent loop ot' such row.

Each loop-spacing strand or lateral E consists ot a single length or section floi" the wire integrally extending,r in an approximately straighttline between spaced pairs of the turns or bends 3 ot the loops D,

As so fabricated, the fabric as a wholel is bounded at one longitudinal end by a ma gin coinprisinpr the bights 1 ,of a series ot' the spaced loops D; at its opposite longitudinal end by a marfrin comprisingv the bends or turns 3 and thc loop-spzminpr strands or laterals 4 opposic the bigrhts l; at one lateral sideby a margin comprising.,r the terminals B and t" bights l. and loops F, the latter being substantially like the main body loops D, with thc except ion, however, that its one leg 2 is ot' double the length of the corresponding leg' ol' the loops D in the body oi: the fabric, whereby its bight l and bend or turn f5 are spaced by a length comprehcnding three of the llaterals e, and its other leg 2 isjoincd by an oblique lateral 4 to the next row of loops D; and on the other lateral side by a substantially similar side margin comprising similarly extended legs Q. all as best seel'i in Figure l.

The fabric, knitted of a single wire to thgis comprise straight lines in both the'longiitudinuls and latcrals, as distinguished from thc substantially circular loops iu rows or chains. as is common to the present knitted fabrics. is one which may uol only bc readiiv tabricawl. but which will also be practically frcc from distortion or strhtchingi'.

The supporting struct urc for my ncw fabric t'or its adaption for use in a springmattrcss. bed.y or the like, comprises heads 5 and rails (l suitably secured together and which l prefer to construct oi' angle iron. as shown. To the heads are attached a number otcoil-springs 7 or othcr suitable yield,- ing members, the springs i' at one longitudinal end being secured in the biffhts 1 of the loops D and the other longitudinal enti en gaging around the bends or turns 3 between the legs 2 of the loops D and the loop-spacing strands et. In this manner, the rows or chains of loops D and the series of laterals E are yieldingly supported relatively to the i Y heads 5.

i 1 the knitted fabric as a whole is suitably secured. Obviously various means may be conveniently employed for such purpose. Inl/the present instance, l employ for such ur ose as shown the securing-bands or` y D "ilii/iks/l() engaging the fabric and the rail 8 time side margin and at the other side /inatrgin engage the fabric with the rail 8 by, I

,'intthe assembling of the spring-mattress or bed, inserting the rail through the edgeloops F between their elongated legs 2' and the oblique laterals 4. In the present instance, l have also shown the terminals B and C 0f the fabric as secured, and thereby fixed, in the springs 9, but obviouslyy the terminals of the fabric may be otherwise relatively fixed, as, for instance, to the body of the fabric itself or to the sag-rail, and other changes in the form, construction, arrangement, and combination of the several parts of my fabric may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters latent is:

l., A substantially square-mesh knitted fabric constructed of a single metallic wire and integrally including a plurality of longitudinal rows of loops and a plurality of laterals for spacing the longitudinal rows of loops, each inside loop of the fabric including a bight, a pair of substantially parallel legs extending in approximately straight lines from the hight, and oppositely disposed bends at the end of each leg opposite the bight, and each lateral consisting of a single length extending inA approxi mately a straight linebetween pairs of the bends of the loops, each intermediate loop of'a row extending at its bight under the legs and over the bends of the next adjacent loop in such row and each outside loop at name to this specification.

insane? the lateral sides of the fabric having one leg of a length double the length of the other leg thereof, each inside mesh of the fabric comprising a pair of loops and a pair of the loop-spacing laterale, some of the later-als at onelateral side of the fabricbeing obliquely disposed to the remaining laterals and providing open sag-rail accommodating edge loops at said lateral side of the fabric.

2. A substantially square-mesh knitted fabric constructed of a single metallic Wire and integrally including a plurality of longitudinal rows of loops and a plurality of laterals for spacing the longitudinal rows ol' loops. each inside loop of the fabric including a bight, a pair of substantially parallel legs extending in approximately si rai glu lines from the bight, and oppositely disposed bends at the end of each leg opposite the bight, and each lateral consisting of a single length extending in approximately a straight line between pairs of the bends of the loops, each intermediate loop of a row extending at its bight under the legs and over the bends of the next adjacent loop in such row and each inside mesh of the fabric comprising a pair of the loops and a pair of the loop-spacing laterals, some ol the laterals at one lateral side of the,

fabric being obliquely disposed to the remaining laterals and providlng edge loops at said'lateral side of the fabric, in comj bination with a supporting structure coinprising suitably connected end and side bars, springs engaging one end bar of the siipporting-structure and the bights of the adjacent end row of loops, springs engaging the opposite end'bar of the supporting-structure and the bends of the opposite end row of loops, a sag-rail attached at one lateral margin of the fabric to the opposite end-bars of the supporting structure, links having engagement with said sagrail and with the outside rows of loops upon said lateral side of the fabric` and a second sag-rail projecting lengthwise through said edge loops upon the other lateral side of the fabric and also attached at its ends to the opposite end-bars of the supporting struc ture.

ln testimony whereof, lhave signed my HARRY M. YOUNG
