This invention relates'to wire fabrics such as more particularly usedin beds, couchesand 'like articles of furniture. 1 V Y An object of "the present invention is to- I provide a wire fabric having links which aref speciallyformedand'which are so arranged v that the fabric possesses the required fienibi-lity, yet is sufliciently rigid so that it will notsag or'be unstable in the direction ofits Own plane, these objects being attained by specially constructing the two kinds vor types of links which are employed. "These objects are accomplished at nogrcate'r ex pense than inthe case of wire fabrics now onth'ema'rketf Thesefbeing ainong the objects of the present invention; the same consists. of certain features off construction and combinations' of partsvtof be hereinafter described and then claimed iwith reference to the accompanying; drawings showing preferred embodiments ofthe invention and in which:

F'abric-tensioning springs 15, "16 are respectively connected withj sid'e, rails; 12; 13, the springs 15 carrying rings 17. The wire fabric of th'e present invention is constructed as follows:

The fabric comprises alternate rows 18 of spaced links ofonekind, each'link having inwardly bent'ends Y19 and an opposite a plan of another form of wire closed end 21. Each -1ink22 of such spaced links has its opposite sides or arms" bent; over at' 23"so as to forin eyes 24;. vThe opposite closed end of each link 22 is formedwith acontract-ed vengaging portion 25 which is'con nected with the straightportions-20 of the V arms by means of inwardly bent :portions26 5, i

for the purpose of providing a, narrow or contracted throat'27. I 1 Rows 28 of other kinds of links alternate with the rows" 18. Each link 28 has amain extended body 29 :formed with two spaced loop portions30 which form throatsBl. The

arms of each-link- 28 are formedwith outwardlybent portions 32and the ends of oiithe space between the eyes 34:is greater thearms are: turned over at 33 tolprovide I eyes' 34, It will be noted thatthe width n than the distance between the inner ends of the armsof each link 28, which is due to v The rows of links 18 are combinedwith' the rows of ner:' v a The eyes 24c ofthe .end'links 22 a seng'aged with' the rings [17. The contracted links 28 in the following man'- portion 25 of eachlink 22 freceives two eyes I 34, 3t'oftwo adjoining links 28 28,- and the end loops next lin-kof the row 18 is similarly engaged bytwo'arrnsof'two 'link'sj28, 28, and soon I in that directionacross the; fabric. The links of each row 18 extend-in one-general direction from side rail toside rail' and the alternating rowsofthe dissimilar links 28 extendgenerally transverselyto the general.

direction offthe links of the'rows' 18.1f'The eyes of the next row 18 :of links are engaged with thetwo loop portions "30,130 -o two adjoining links-28, 28, and the fabric is built up in that way substantiallythrough-j out, so that there are rows of links 18; of

one kind'which alternate with rows'of 'links 28 of the other kind. The arms of the links 28 extend in the same general direction as the links 18, and the links of any two adjacent rows are in ofiset relation in one row to the other row. When suitable tension is placed upon the so-built-up fabric it will be held quite taut'by means of the tensioning springs'.15, 16, with which the links aresuitably connected, Other springs '35, 36 are at V the side rails 12, 13 for tensioning :in the usual manner the border links 37, 38. The

border links 37,, 38 finishcthe fabric and atthelsame time-gi-ve the. necessary stiffness to the fabric in a direction lengthwise of the side rails 12, 13. While the construction illustrated and described produces a more or less rigid structureit is not too rigid to allow of the desired flexibility of action. In

' this connection it will be noted that the inward f'bows 26 of the links 22 make them moretrigidthan otherwise, due to the fact a i that the inwardly bowed portions 26 are bent 4 in the plane of the link 22,'inthis respect functioning somewhat similarly to'the outward bends 32 of the other links 28.

Also

' it Willbe' noted that the location or fixing of theeyes 34 of the links 28 in position in .the closed ends of the links 22 is rendered more definite and certain by reason of :the contracted throats 27 of the links ,22;vand it will also be noted that the eyes 34 of the links 28 are substantially parallel and that where these eyes of "two separate adjacent links 28engage'in any one throat 27, they bear mutually oneon the other for some distance, s as-to' render these connections more;

reliable. The parallel bearing surfaces of the arms of the links 28 thus contribute to the general firmness or steadiness of thewire fabric in its own plane, while'at'the same time the'fabric is sufficiently resilient for the.

intended purpose. v

In Fig-'Tanotherform of the improved 1 fabric is illustrated, and in; this form the principles and general construction are the same,-iexcept-that the links 39 which correspend with the links 22 of theother form are shorter, while the links 40 which correspond .with the links 28Yof theother form have longervarms. -In other words,-the links 39 and-c740 are of substantially the same length in'the direction of their arms. a J 1 WhatI claim as new, is: V I LEA wire fabrieincluding alternate rows of links, one row comprising spaced links wh ch extend in" one general direction, the

such construction and arrangement being repeated throughout the-fabr c.

2.;A-wire fabric including alternateirows' i of links, one row comprising spaeed links which extend'inv one general direction, the closed end of each of the spaced links having a contracted engaging portion and the 5;
