WOVEN-WIRE BED-BOTTOM.

SPECIFICATION forming part 0f Letters Patent N0. 581,405, dated April 27, 1897.

Application iilecl June 8, 1895. Serial No. ",()56. (No model.)

T0 all whom t may concern:

Be it known that I, FRANCIS G. GALE, of lVaterville, Province of Quebec, Dominion of Canada, have invented an Improvement in Voven-Wire Bed-Bottoms, of which the followingdescription, in connection with the accom panying drawings, is a specication, like letters and gures on the drawings representing like parts.

This invention has for its object to improve an d cheapen the construction ot' bed-bottoms of that class having lozenge or V shaped links or meshes and which are connected to the end rails of a mattress-frame or to a bedframe by strong spiral springs. Bed-bottoms of this class possess one advantage in particular over the ordinary woven-wire mattress-viz., a diagonal connection is formed from end to end of the frame to which the bed-bottom is connected.

In carrying out my invention I form the bed bottom by weaving together several strands of wire extending lengthwise the web, said strands being cramped or bent into zigzag form, presenting sharp angles at the bends, and the weaving being accomplished by looping or linking these zigzag strands into one another, thereby presenting lozengeshaped meshes. The edges of the web thus formed present a series of V-shaped links, those on one edge pointing in the opposite way to those on the other edge, and, if desired, the wire forming the edge of the web may bemade considerably larger gage than the other wires for additional strength. The web thus formed is made of a width corresponding to the length desired for the bedbottoms, and is subsequently out up into sections of suitable widths for the bed-bottoms. The severed ends of the wires formed by cutting the web may be twisted around the finishing-strips. In connecting the bed-bottom thus formed with the mattress-frame or bedframe the end tension or supporting springs are connected by links with the V-shaped links formed upon the sides ofthe web, which after the web is cut off will constitute the ends of the bed-bottom, or said end supportingsprings will be directly hooked into or connected with said V-shaped links without the interposition of such supplementary links, and if larger wires are employed for the sides of the web it will be seen that very strong and durable end links may be presented to receive the supporting-springs or the links connecting said supporting-springs with the bed-bot tom. As I prefer to make the lozenge-shaped meshes of the web quite small, the V-shaped links at the sides will be very close together, and hence the necessity of the supplementary links in order that large end supportiu gsprings may be employed.

Where two rows of supplementary links are employed at the ends of the bed-bottom, connecting thereto the supporting-springs, the links of that row adjoining the bed-bottom will be formed with one leg Vlonger than the other. A

Figure l shows in plan view a portion of the web embodying this invention; Fig. 2, a detail showing the severed ends of the wire twisted around a rod or bar; Fig. 3, a detail showing the severed ends of the wire clenched into and thereby connected with a two-strand cable; Fig. 4, a plan view oii'a completed bedbottom connected to a frame by end supporting-springs and two rows of interposed supplementary links.

The' web consists of several zigzag strands of wire a, extending lengthwise the web, the bends or angles being made quite sharp, and said zigzag strands are looped or linked together or into one another. The web thus formed presents lozenge-shaped meshes with V-shaped links b at the sides, which project in opposite ways. (See Fig. l.)

If desired, the outer or side wire extending along each side of the web may be made of larger-gage wire than the other wires.

The web thus formed is out up into sections of suit-able widths desired for the bedbottoms, as represented by dotted lines, Fig. l. The severed ends a of the wires formed by thus cutting off the sections are utilized in forming an edge for the bed-bottom ot' greater or less stiffness by twisting them aroundthe finishing-strips-as, for instance, they may be twisted around a finishing-strip consisting of a rod or bar d, as represented in Fig. 2, or they may be clenched into a twostrand cable g, as represented in Fig. 3.

The bed-bottom thus formed may be connected with a mattress-frame or bed-frame by suitable end supports, which engage the IOO V-shaped links at the ends thereof, which lends of the `wire strands are twisted, sublinks form the sides of the continuous web. For inst-ance, I may employ strong spiral end springs e, which may be connected with said V-shaped links by two rows of interposed supplementary V-shaped links ff', having hooked ends, or a single row of such supplementary links may be employed, or the end springsmay be connected directly with the V-shaped links I) of the bed-bottom, but as I make the lozenge-shaped meshes of the web quite small one or more rows of supplementary links are found to be necessary. When twol rows of supplementary links f f are used, one leg of each link of the row marked f is shorter than the other leg-as, for instance, referring` to Fig. 4, the points l 2 3 are connected with each spring, and in the row of links fthe legs-i 5 are longer than the legs 4c 6, as the linksf close np some under strain, making the distance longer from the spring to 5 than to 6; also there are two connections at the points 5. If the links f' were not made in this manner, one leg would, disengaged under strain.

The bed-bottom constructed of a continuous web, which is provided at the sides with means for receiving the end supports, possesses many obvious advantages.

I claiml. A bed-bottom composed of a section out oit' of a continuons web which consists of several strands of wire extending lengthwise of the web, bent into zigzag form and woven together at the bends, thereby presenting V- shaped links at each side which project in opposite ways, and nishing-strips at the sides of the bed-bottom around which the severed stantially asdescribed.

2. A bed-bottom composed of -a section cut oit' of a continuous web which consists of several strands of wire extendinglengthwise of the web, bent into zigzag form and woven together at the ends, thereby presenting V- shaped links at each side which project in 0pposite ways, and twisted-Wire inishing-strips at the opposite sides of said bed-bottom with which the severed ends of said wire strands are interwoven, substantially as described.

3. A bed-bottom having V-shaped links at the ends, a row of supplementary links f' at each end, one leg of each link being longer than the other leg thereof, for the purpose of preventing one of the legs being disengaged while the other is under strain, the supplementary row of links f, connecting the V- shaped links with the links f, and the spiral springs e connecting the links f to the frame of the bed-bottom, substantially as described.

Li. A bed-bottoni having links at each end for the purpose of connecting it to the bedbottom frame, each link having two legs, one leg of each of said links being longer than the other leg thereof, for the purpose of preventing one ofthe legs from being disengaged while the other leg is under strain, substantially as described.

In testimony whereof I have signed my naine to this specification in the presence of two snbscribin g witnesses.

FRANCIS G. GALE.
