Be it known that LEDWARD Nicnnnson, a citizen ofthe United States, residing at Buffalo in the county of Erie and State of New have invented a' new 'and useful' Imthe following is a specication;

This invention relates toim'provements in bed-bottom' fabrics of that class vwhich are composed of a plurality of wire-links which areconnected orhingedf together in such a mannerthat the fabric is flexible and can' be folded `both transversely and longitudi- The 'object of this'inventi'on is to provide a bed-`bottom fabricof this kindA of simple and economical'construction in which the links are connected together end to end in longitudinal vrows and the links in each row are connectedat pointsintermediate of their ends with the corresponding links'in the adj acentv rows in such a manner as to form continuousparallel strands which extend from end yto end of the fabric both longitudinally and transversely thereof. f Y

'A further objectof this,` invention is to provide 'a' bed bottom having links which ywire arranged side by'side longitudinally of mediate of'theirends, transverselyof the fabric, in such` a manner that any lateral or side strains upon the links will not tend to spread'them-vapart, and 'the end and v side be. distributed throughout the link insteadv In theaccompanyingdrawings: Figure 1 is a fragmentary plan view of a bed bottom provided with a fabric embodying'the in- Vention. Fig. 2 isa perspective view,on any enlarged scale, of one o f'vthe longitudinal andone ofthe transverse links of the fabric tionfv` Like reference characters referdtowlike parts in the several figures. f .f l

wise ysuitably connected together trans versely of the fabric. Each link is suitably formed by bending a single piece of wire.

It isprovided with a hook at one end anda loop atthe opposite end which hook and loop are adapted to engage similar `coperating parts on the adjoining links and are lconnected .together -by double parallel bars or strands of wire which are arra ed side the ends of thek ink with suitable means Patented aan. a, ieri.

whereby the linkFcan be connected tranisversely ofthe fabric to the correspondingV links in the rows -on the opposite sides therei of either by separate transverse connecting links, as shown inFi l, or bya laterally extending' arm formed integrally with the link, as shown in Fig. 3.

In the construct-ion shown in Figs. l andv 2, 'A A. represent the'longitudinal links of the fabric and BB the transverse links. Each longitudinal link is rov-ided at one end with a loop a and at'its opposite end4 with a hook portion a, which'. are connected together on one side of the link by an-integral continuous bar or strand a2 and on the other side of the link by bars or strands as and 'at which are continuations of the Wire forming the hook and loop ends of `the link andare connected together at a point approximately midway between the kof this transverse link engaging 1n theloo of the corresponding longitudinallin in the rowV next adjacenton that sidel It is .of vno consequence vwhich of the bars z3 yand -ais `bent to'forin ythe loop a5 and the vcy'e .a6 and either may be used for that pur:- pose, and any suitable form of transverse .link may .be usedfor connecting the cor-.

responding loops and eyes of the di'erent links. The bara* isprovided with a hooked I end or eye 'which engages in the loop a?" for connecting the hars as and c4 together. Any' suitable 'fraineqmay be employed .to which the fabric can be 'securedin any .de-

- sirable manner. The frame shown is of usual angle-iron construction, having end rails C vand side rails D. The fabric is secured to the end rails by springs E which connect-the end links of each row with the rails.- rlhe fabric may also be connected with the side rails if desired, although this connection is generally not necessary.

The link :hown in Fig. 3 is similar to that shown in Figs. l and 2 with the exception that the bar a3, instead of being bent to form the eye a6 adjacent to the sidr-A of the link, is extended laterallyl of the link to form the transverse armf having a hooked end f which is adapted to engage the loopA hooked end g "which embraces the neck portion of theA loop g `and connects thetwo bars on that side of the link together.

In the' modified construction shown in Fig. 5- the bars as. and a* are bent or twisted around each other so that they interlock with their ends extending laterally on opposite sides of theV link and terminating in yeyes i1. on each side thereof for engagement with the transverse links B.

If itis desired to do away with the sep-A arate transverse connecting links B, the

links shown in Figs. 4 and 5 may be provided with laterally extending hooked arms, such as that shown in Fig. 3, for connecting them together transversely of the fabric. This can be easily done by extending the end of one of the bars forming the link laterally from one side' of the link at the` joint where these bars are connected *..u-

gether and providing this extended arin' with a hooked end for engagement with the` loop or eye vof the adjacent link.

In all these constructions it Will. be noticed that the eye and loop on the opposite sides of each longitudinal link are connected together so that they are directly opposed to veach other. Any lateral strain on the lmk in either direction will thus be directly re sisted by the opposite transverse member and there will be no tendency to draw apart the longitudinal bars of the link, or weaken itin any way. y j v The arrangement of the transverse connecting portions of the longitudinal-'links intermediate of the ends thereof enables the links to be secured together in a transverse direction by sideconnections which are separate from and independent of the end connections of the links. The side and end con# nections thus do not come into contact with each other and interfere with the free movement of the links relative to each other, no1' is there any danger of either connection becoming distorted or bent'out of operative position by any stra-ins which may be rcceived by the other connection. This greatly` of and terminating intermediate of the ends ofthe link and forming portions for the pivotal connection of the/link with adjoining links on opposite sides thereof, said link having at its opposite ends portions for connection with coperating portions at the` ndsh of adjoining links, substantially las set ort f2.
