To all whom it may concern).- 7

Be it known that 1-,JAMES B. RYAN, a citizen of the United States,residing at the city of New York, countyand State of New York, have invented anew and useful Im provement in BedBottom's,. of which the following is a specification.

My inventionrelates to improvements in bed-bottoms, and particularly mum class of bed-bottoms in which woven-wire fabric forms the chief elementof the primary pressure plane. It is illustrated in the accompanying drawings, referred to herein, like letters referring to like parts in each figure thereof. i i

In thesaid drawings, Figure '1 is a plan view of a bed-bottom embodying my invention. Fig. 2 is a modification of the same. Figs. 3 and 4 are modifications.

A represents the frame of "the bed, upon which the woven-wire fabric 13' is stretched.

O are elastic wire cables, such as are. com: monly used in the trade, having their two ends secured to the end rail A of the frame either at or near the ends ofthesaid rail or. having one end connected to the end thereof and the other secured at or near the middle. These cables extend about half-way of the length of the bed and are disposed in a V shape under hooks are preferably of an' S shape orother bent or curved form, so as to possess a certain amount of elasticity, forming a non-rigid connection between the cables stretched from either end rail of the bed. The hook F is provided with a turnbuckle for the purpose of adjusting the tension of the cables. Where the hooks are not provided with turnbuckles, the tension may be adjusted by using hooks of different lengths to increase or diminish the stretch of the cables, as required.

The chain E serves as a coupler when two or more of my supporting devices are used on one bed, as shown in Fig. 1, and are adapted to connectthe cable-hooks and prevent them from spreading laterally. It is provided with a small hook e at either end, by which it may be connected to the said cable-hooks at the part (1, as shown inFig.'1, or otherwise, or

together than the length of the chain will al- 'low the chain may be looped through the hooks andsecured by passing the hooks 6 through one of its own links or by hooking them together, and in this manner the cablehooks may be coupled at any desired distance apart. I

a By the use of this device various advantages are obtained not heretofore secured by such reinforcing contrivances. One of these advantages is that the S-hook is very easily placed in position, requiring simply to be hooked into the loops 0 of the cable, and may be as easilyremoved therefrom, and'bytheir use the cables may be firstsecured at their ends to the frame of the bed-bottom and then connected by meansof thehook instead of passing them first through the center plate or other connecting medium and then securing their ends to the frame, as has heretofore been the custom in themanufacture of these beds. This admits of the cables being more easily and uniformly stretched since it is difficult to secure the endsof the cable to theframe while under tension and a uniform stretching of the cables is not always in this manner obtained. By measuring thelength of the cableto be usedfor' each V or loop, so that the desired amount of stretching will be required to draw each pair together and secure them at the center of the bed by the hook an absolutely uniform tension may be insured. The cables also being continuous from end to end and passing through and not terminating in the hook or link will have the tension distributed evenly throughout their entire lengths, and thus the stretching and consequent loosening of one diagonal length more than another is prevented. When the cables become loosened, as they invariably do under long use, a ready means of tightening them is aiforded by the use of these hooks by replacing any given hook by one of lesser length, and thus drawing the points of the cable-loops nearer togethenand, again, by the use of the turnbuckle F (shown in Fig. 2) the tension of the cables may be easily increased or diminished to any required extent to accommodate the weight of the person using the bed. The S-hooks having also a certain amount of' elasticity make the support enwhen itis desired to couple these hooks closer tirely elastic from end to end of the bed.

The chain E is of advantage when used in connection with my support, as the said support is adapted to be used for a full-sized bed and offers advantages not heretofore se cured by these supporting devices, since by its use an extensive lateral adjustment of the support is allowed. This is of great advantage, inasmuch as the weight when one person only is occupying the bed is generally entirely in the center, whereas when occupied by two persons the weight is disposed at either side thereof. By coupling the two hooks together with the link or chain E the support is disposed entirely beneath the center, as shown by dotted lines on Fig. 1, and an effective reinforcement for the fabric is provided when the bed is occupied byone person, while when the coupler is removed and the supports disposed at either side of the bed it offers an effective reinforcement for the fabric when the weight of two persons is superimposed thereon. The total length of cable in both sides of each V will be the same when the hooks are drawn toward the center as when they are disposed at either side, and the support will therefore remain in a central position without the assistance of the link F or chain E. The link, however, I have found of value in preventing the hooks from spreading when pressure is imposed upon the center of the bed.

I am aware that elastic cables have hereto fore been used as a support for a woven-wire bed-bottom, arranged in various ways, and that they have sometimes been stretched from the corners of the frame and secured at or near the center to a plate, cross-tie, or like device. I do not claim this arrangement, broadly.

\Vhat I claim is- 1. In a bed'bottom the combination of a frame and an elastic fabric stretched thereon, and two or more endwise-clastic cables disposed beneath the fabric, and having their ends secured to the end rail, a hook at or near the center through which said cables pass and by means of which they are connected to each other; said hooks being lengthwise adjustable and adapted to regulate the distance between the parts of the cables passing through it.

2. In a bed-bottom the combination of a frame and an elastic woven wire fabric stretched thereon, and a plurality of endwiseelastic cables; two or more being secured to each end rail of the frame and connected centrally in pairs, extending from opposite end rails, and hooks connecting said cables; said hooks being secured together by means of a transverse tie.
