1BEDSPRING FABRIC.

Specification of Letters Patent. Pat t Jan. 31, 192

Application filed November 1, 1918. Serial No. 260,646.

To all whom it may concern:

Be it known that l, Jonson L. McKnLLAR, 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 Bcdspring Fabrics, of which the following is a specification. V Y I The invention pertains to metal spring fabrics for use on bedsteads for supporting the usual hair or other soft mattress, and it consists in the novel features and structure hereinafter described, and particularly pointed out in the claims.

The spring of my invention comprises a main carrying frame of usual or any suitable type and a fabric composed of inter engaging links of special outline connected by coiled springs with the end bars of said frame, the structure as a whole being complete in itself and adapted to be handled as a unit and applied to or removed from the customary bedstead. One of the purposes of my invention is to provide a fabric whose links may be readily constructed and assembled and have an efficient yielding action due to their parv ticular shape; and another object of the invention is to provide a spring fabric which will be durable and the links of which will maintain their shape under strain. Each link is approximately of U-shape having loops at the ends of its transverse bar, hooks at the free ends of its sides and loops in said sides adjacent to said hooks.

Theinvention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Fig. 1 is a top View, partly broken away, of spring constructed in accordance with and embodying the invention;

Fig. 2 is a top view, on a larger scale, of'

bars 10, 1'1 and side bars 12 connecting said end bars, in a manner well understood in this art.

, The fabric of my inventionis composed of a connected series of transverse and 1011- gitudinal rows of links formed of wire, two of which linksare separately illustrated in 2. The links are numbered 1 1, and all of the links are of corresponding formation, each-being of vapproximately U-shape and comprisincr sides 15 and a connecting member 16. The links 1% are each formed from one piece. of wire, and the sides 15 have at their free ends hooks 17 which are formed loops 19, these loops 19 being formed partly out of the metal of the sides .15 and partly out of the transverse member 16, the bend of the loops being formed wholly out of the wire of the member .16 which is offset inwardly, as shown in Fig. 2, to create the loops 19. The, loops 19 are on the same horizontal planeas the transverse member 16 and adjacent portions ofthe sides 15;

and the loops 18 of each link are respectively bowed upwardly and downwardly in opposite. directions, as represented in Fig. 3, to accommodate the loops 18 of the adjacent links with which they are engaged.

The links 14in each transverse row thereof are engaged with each other at the loops 18, the adjacent sides of each two links being passed one within the other link and'the loops thereof broughtorhooked together, as

shown in Figs. 1 and 2; and the links 145 in each longitudinal row of links, are hooked together by the engagement of the hooks 17 of each link with the loops 19 of the next adjacent link. The hooks 17 are offset inwardlyfrom the general longitudinal plane of the sides 15 of the links so that they may be caught into the loops 19 of the adjacent links in a longitudinal row thereof and lie flat and without twisting or straining the sides of the links, this also resulting in the production of a desirable spring fabric in which all the links in a longitud nal r ow thereof are freely hinged together 1n serles.

It is an important feature of my spring fabric that the loops 18 are adjacent to the hooks 17 since thereby I omit the formatlon of unduly long spaces between the ad acent side members of interengaged links at the open ends of the links.

The links 14 in each transverse row thereof are therefore hooked and hinged together at the loops 18, which are adjacent to the hooks 17, and the links 14 in each longitudinal row thereof are hooked and hinged together by-the engagement of the hooks 17 of each link with the loops 19 of the next adjacent link, which loops 19 are set inwardly from the general longitudinal plane of the sides of the links and are in line with the hooks 17. The connection of the links 14 with one another at the hooks 17 and loops 19 is'inwardly from the general longitudinal plane of. the sides 15 of the links; and the connection of the links with one another at the loops or bends 18 is outwardly from the general longitudinal plane of said sides 15 and adjacent to the connections afforded by the engagement of the hooks 17 with the loops 19 of therespective links, and this special construction and connection of the links results in the production of a superior fabric for the purposes for which it is intended to be used.

The loops 19 of one end row of links 14 are connected to helicals 20 by means of suit able wire connections 21,22, as shown at the upper end of Fig. 1, which helicals 20 are secured to the end bar 10 of the general frame; and the hooks 17 of the other end row of links 14 are suitably connected with helicals 23 secured to the other end bar 11, as shown at the lower end of Fig. 1.

The main features of my invention reside in the fabric formed of the transverse and longitudinal rows of links 14 of the character and interlocked together in the manner described, whereby a highly efficient, durable, and desirable spring fabric for beds is produced. 7

What I claim as my invention and desire to secure by Letters-Patent, is- I 1. In a bed-spring of the character described, a fabric comprising transverse and longitudinal rows of links of approximately U-shape interengaged with one another in series at their ends and sides, said links having parallel hooks at the free ends of their sides, loops at the ends of their transverse member, and outwardly and oppositely bowed loops in said sides and adjacent to the free ends thereof and to said hooks, and said ing parallel hooks at the free ends of its I sides and set inwardly from the general longitudinal plane thereof, outwardly bowed loops in-said sides and which are respec tively bent upwardly and downwardly in opposite directions and are adjacent to the free ends of said sides and to said hooks, and loops at the ends of its transverse member and which loops are in line with said hooks, and said links being connected together by interlocking the side loops of one link with the sideloops of adjacent links and by engaging the said hooks of the respective links with the said loops at the ends of the transverse member of the respective adjacent links.

3. In a bedspring of the character described, a fabric comprising transverse and longitudinal rows of links of approximately U-shape interengaged with one another in series at their ends and sides and each hav ing parallel hooks at the free ends of its sides and set inwardly from the general longitudinal plane thereof, outwardly bowed loops in said sides closely adjacent to said hooks, and a transverse member connecting said sides and. which is offset inwardly to form loops at'the ends thereof inwardly the general longitudinal plane of said sides, and said links being connected together by interlocking the side loops of one link with the side loops of adjacent links and by engaging the said hooks of the respective links with the said loops at the endsof the transverse member of the respective adjacent links.

Signed at Brooklyn, in the county of Kings and State of New York, this 25th day of October, A. D. 1918.
