SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 368,90-5, dated August 23, 1887.

Application tiled August 13, 1886. Serial No. 210,799, (No model.)

To all whom ifm/ay concern,.-

Beit known that I, J OHN H. BATTOHER, a

citizen of the United States, residing at New 4bottoms in which awoven-wire bottom or bottom of analogous'fabricis employed. It is a known fact that one great ditticulty in and objection to bed-bottoms of this fabric is the tendency of such fabric to become misshapen and to finally permanently retain such misshapen condition. Now, the object of this invention is to remedythis evil; and to this end the invention consists in a bed-bottom of woven wire or analogous fabric supported cen; trally by upholsterers springs, and stayed laterally by a series of vertical springs arranged below its level between the end rails, and connected at'top to the side ofthe fabric, and rigidly secured at their ends to the frame, so that as weight is applied to the bed- 'bottom t-he side springs will cant over and becomepractically part of the bed-bottom, and thus prevent it from becoming permanently misshapen, while at the same time they add strength and permanence to the bed-bottom without in the least detracting from its ileKiconnected, as by corner irons, c.

bility.

In the accompanyingdrawings, in the several gures of which. like parts are similarly designated, Figure lis a plan view illustrating my invention, the woven-wire fabric being 4shown only in part. Fig. 2 is a perspective view of one corner. Fig. 8 is a plan view of one cor.

ner, showing the side springs deflected, as they pressure.

is composed of woven wirev or other analogous bed-bottom fabric secured to the end rails in any suitable manner. This bottom fis of less width than the frame. Parallel with and just above the upper edges of the side rails are arranged a series of interlocking coiled springs or coils of wire, g. I have shown three such interlocking coils,- arranged upon each side of the frame and secured, as by staples h, (see Fig. 4,) underneath the corner irons, c; but I do not limit my invention to any particular device or devices for retaining the said coils or springs in position above the side rails. I prefer that these side coils be of somewhat greaterl resistance or strength than the coils of the bed-bottom proper when said bottom is made of woven wire. These side coils are connected by their upper coils to the side coils of the bottom proper by means of any suitable fastening-links, i, at intervals along the sides of the bottom proper.

It will be noticed that the bottom proper is suspended by its ends from the end rails, and normally stands above and between the side coils, so that when weight is applied to the bottom the bottom tends to sink between the side coils, and if the weight is sufficient to depress it that far the pressure is transmitted through the links to the side coils,which then receive a cant inward toward the bottom proper, as indicated by the full and dotted lines in Fig. 3, thus making the side coils a part of the bottom proper when under such In this way the tendency of the bottom to assume a set is overcome and the bed is preserved in its normal shape, for as soon as the weight is removed the bottom proper and the coils will resume their normal positions. Of course it will be understood that the upholsterers7 springs esubserve their usual function in this arrangement of supporting the center of the bedbottom,where the greatest weight usually falls, and these springs also assist in retaining the bedbottom in its proper shape.

I am aware that itis old to insert a 'wire in the edge of the woven-wire fabric on each side of the bed, or instead of a wire to use a rod in ICG venting the mattress from being narrowed at the middle, and to counteract the strain of the spirals of the webbing upon the brackets.

I am also aware that it is quite common to provide the longitudinal edges of Woven-wire mattresses with a double, triple, or multiple coil, so as to increase the stiffness or reenforce the strength of the mattress at those points.

What I claim is- 1. A bed-bottom consisting of a frame, abottom proper of woven wire or analogous fabric secured only by its ends to the frame, and only to the end rails of such frame, series of side coils or springs wholly separate in construction from the bottom proper and secured by their ends to the frame and arranged above and in the saine vertical plane as the side rails, and links i, for connecting the side coils and bottom proper and springs c, substantially as shown and described.

2. In a bed-bottom of woven wire or analogous fabrie,side coils, g, arranged parallel with and above and in the same vertical plane with thc side rails and secured to the frame by their ends only, and a bottom proper arranged above z5 said side coils and connected therewith by links, but otherwise wholly independent of said coils, whereby7 as weight'is applied to the bottom proper, said bottom will sink between the said side coils, and in sinking draw 3o or cant said side coils over toward the said bottom, substantially as described.

In testimony whereof I have hereunto set my hand this 3d day of August, A.D. 1886.

JOHN H. BATTCHER.
