IMPROVED SPRIG-BED BOTTOM.

To all whom 'it may concernl- Be it known that we, Hman Rvssnnn and Mrnox S. FULLER, both of Nashville, in the eountyofBairy, and State of Michigan, have invented certain new and useful Improvements in Spring-Bed Bottoms; and we do hereby declare that the following is a full, clear, and exact description ofthe same, reference heilig had to the annexed drawings, making a partot' this speeiication, in whichi Figure 1 is a plan of the under side ofthe bed-bottom.

lFigure 2 is an end elevation, with the eovering-slat removed.

Figure 3 is a longitudinal vertical section tlnough one end of a spring-bed slat.

, Similar letters of reference indicate like parts in all thetigures.

Our invention consists of an iniproved mode of hanging the bed-bottoni slats on elastic bands, so that the slats may be free to turn, the bands being sus-v pended or fastened without screws or nails, and in such manner that they may be readily renewed whenever it maybe necessary, and the whole so arranged as to adapt the bottom equally well for portable as for stationary' use.

To better enable others skilled in this mechanical branch to constmictour invention, we will now proceed to describe it, with the aid of the drawings, an'd the letters of reference marked thereon.

A represents ordinary woodenl bed-bottom slats, having a round tenon or journal, a, formed on each of their ends. These journals tit so as to turn freely in holes bored in wooden selnicircular bearing-blocks, l), which are supported 011 strips of 'the `lnaterial known as rubber webbing, or ou bands of any other kind possessing the required elasticity, shown at u'.

Te usually forni the bearing-blocks by turning in one-circular piece, with a. groove around the Aperiphery to receive the elastic webbing, and then saw them in two, after boring for the Slat-journals.

C represents the head and foot cross-bars, to which the elastic webbing is connected, for supporting the blocks and slats.

Vile hang the bearing-blocks and suspend the webbing from the cross-bars, by passing said webbing in a serpentine course around the circular part of the block, within the groove, and around the walls of recesses of a dovetail character, cut in the cross-bars C, opposite the narrow spaces between the blocks in'range, and

inselt a centre key, so that it may be easily taken out. A very convenient mode of doing this is shown in the enlarged elevation, ig. 2, by boring round holes nearly through the bars, and cut-ting away suflicient wood to permit the passage ofthe two thicknesses of webbing. lVe then insert either round or pear-shaped wooden keys in the cent-re, to till (with the webbing) the whole space Kso made, Yas indicated at D.

In order to confine the keys in place, we hang the bearing-blocks so that their outer faces will project beyond the sides of the cross-bars a distance equal to the thickness of a wooden strip, seen at S, which we screw on to the outside of each cross-bar, over the keys, and thus secure both keys and webbing in place.

There being no nails, screws, or other metal attachments to the webbing, it wears longer, and it will be lseen that our arrangement makes it a comparatively easy matter to take oi stretched or worn webbing and replace it with new, or to remove it temporarily to scald the wood-work, if infested with bugs, 'as all' that is necessary to do is to unsorew and screw on'the covering-strips, and remove and replace by hand the webbing wand key D.

The slats will turn in their bearings so as to adjust themselves at any angle to suit-the contour and movements of the body, and, when sprung down by use, can be reversed. i

Our bed-bottom may be secured in a bedstead by any of the well-known means, and for military or other portable uses the slats can be taken out, and all the parts tied together for transportation. It is but the work of a few minutes to put the parts together, and an et tempore bedstead can be created by temporary supports at the ends of the cross-bars, to hold them up from the ground.

We do not cla-im, broadly, supporting lbed-bottom slats on elastic webbing; but, having described om` invention,

That we claim as new, and desire -to secure by Letters Patent, is the following: y

lVe claim the journal-slats Asupported in bearingblocks b, in combination with the elastic webbing fw, and recesses and keys D in the cross-bars C, substantially as and for the purpose specied.
