IMPROVEIP BED-BOTTOM.

vThe Scheule referredv to in these Letters Patent and making part of the same.

,Bed-Bottoms and liattresses; and I do hereby declare that-the following is a full, clear, and exact dcscrption thereof, referencebeing had to the annexed drawing making part of this specification, in which- AFigure 1 is a perspective view of my improved bedbottom and mattress as they appear when combined. i Figure 2 is a bottom view of my improved mattress, showing the end reduced in thickness, and the means of securing it to the hed-bottom.

Figure 3 is a pla-n view of aI portion of .the wires which constitute the supportfor the mattress', and showing the cleat for fastening them to the cnds'of the bed-bottom.

Corresponding letters refer to corresponding parts in the several figures.

This inventiou'relates to that class of bed-bottoms which is supplied with a series of small wires woven or interlocked together, in such a manner as to form a clothjor supporting the mattress; and

It consists iu combining therewith a mattress of peculiar construction, and, also, in combining therewith straps for the purpose of unit-ing them together, as

will be more fully explained hereinafter.

Bed-bottoms of this type have heretofore been coustmcted of two thicknesses of wire-cloth only, and, in order to strengthen those portions which had to sustain the weight of the persons resting upon it, an additional thickness of cloth has sometimes been placed under the upper thickness, and attached to it at t-hc sides and at the center, or narrow stripshave been piaced under it at these points Vbut the wires of these additional thicknesses have never been interwoven with those of the upper cloth, so as to constitute in reality only one thickness of cloth, strengthened, where required, by iuterweaving of additional wires to rcduce the elasticityy of the cloth at such points.

I propose to construct a bottom consisting of two or more thicknesses of wire-cloth, the wires of which interlock longitudinally one with the other, as clearly shown in fig. 3.

To preventthe wires or cloth, which supports the mattress, being too much depressed inthe center, I at that part place another thickness of cloth, the wires of which are interlocked with or woven into the main body ol' the cloth, by which means it is very much strengthened at that point.Y The same means are employed to strengthen this support atits sides, where the cloth is also supplied with an additional thickness of wires interlockcd with those of the other thicknesses in the manner clearly shown in fie. 3 of the drawing.

The cloth thus made is fastened to a frame, A, made of boardsof suitable thickness, its length and width being such as-to adapt it to the bed to whichit is to be applied.

The sides or longest parts of this frame are to be hollowed out in their central portion, as shown in fig.

,nailed or screwed to the ends of the frame, it covering the ends of the wire-cloth, thus holding it in position, as well as preventing it from injuring the mat,- tress. '.lhc ends of the wires or of the wirc-clotharc attached to the upper surface of the fra-me, while its sides 4are attached to the lower surface, thus'giving it a greater amount of elasticity at its center' longitudinally than at its ends.

A copper rod or wire, A2, is run around the frame A, secured to it in any suitable manner, which may be used in connection with staples to fasten the wires to the sides, in themanner shown. But its printipal office is to conduct ofifl the electricity in case the bed is struck by lightning. Where its cndsmeet they are united together and run to any desired point away from the bed.

The mattress B, to be used in connection with the bottom' hcreinbefore described, is constructedwith its ends B' reduced in thickness on the under side, for such a distance as to permit the main body tolie upon the wire-cloth between the cleats A1, or the end-rails of the frame A, so that it may rise and fall with the movements of the wires without subjecting such ends to any extra wear ou the cleats "or end rails, and for the further purpose of keeping the upper surface ol' the mattress level, or nearly so, under allordinary cir` cumstances.

The mattress is provided at each end with a series of straps, C, made of elastic material, by preference, and fastened to it at the under side iu any suitable and substantial manner at one of their ends. The other end is provided with an eye to hook over broadhcaded nails c, driven at the propel' points into the end rails of the frame A, for the purpose of securing the mattress to the bottom.

The eye in the straps is covered on one or both sides by a metallic plate, c', with a round central aperture, large enough to admit the head of the nail, and narrow slots extending ,vertically from each side of the central hole to permit it to move over the shank ofV the nail in' the rise or fall o f the mattress.

What I claim, anddesire to secure by Letters Patent, is-' l. The combination of the bed-bottom herein described, and the mattress B B', substautlly as set 1n testimony whereof I have signed my name toforth. this speeicationin presence of two subscribing wit'.-v
