Nrrsn STATES ISAAC A. SER'GEANT, OF SPRINGFIELD, OHIO.

HVIPROVED SPRING BED-BOTTOM.

Specification forming part of Letters Patent N0. 23,786. dated April 26, 1859.

.To aZZ whom it may concern:

Be it known that I, IsAAo A. SERGEANT, of Springfield, Clark county, Ohio, haveinvented a new and useful Improvement in BedBottoms; and I hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

My invention relates to, rst, the'provision of a combined yielding frame with a longitudt nal arrangement of cords of simple construction, easy adjustment, and enduring elasticity; second, a provision in connection With the first named for adaptation tothe purposes of a recumbent conch; third, an arrangement for the temporary fixture of the yielding or upper portion of the bottom.

I n the accompanying drawings, Figure 1 is a perspective view representing my improved bottom adapted to a common sleeping-bed. Fig. 2 is a sectional elevation thereof. Fig. 3 exhibits the arrangement adapted to the purposes of a recwumbent couch.

A is the bedstead-frame.

Parallel and near to the foot-rail is a rail, B, whose top has a set of belaying-knobs, a. A little in front ot and lower than B is a second transverse rail, I), adjustable in height within notches E in the side rails. In connect-ion with these stationary parts I employ a yield' ing stretchcrframe, consisting of two similar longitudinal wooden bars, C O', rigidly united attheir upper ends by a cross-bar, C". These bars O O', resting in notches in the rail B, press with their lowcrends against the bottom ofthe supplementary foot-rail B. Studs c retain the bars O C in place. The cross-bar O has a set of knobs, b, similar to those on the rail B. Around these knobs the cord is laced in parallel longitudinal rows, as shown. The stretcher heilig thus held by the cords, the whole becomes a yielding bottom, whose powerful yet sensitive elastic functions are prevented under any load from that of a heavy man to that of an infant.

The elasticity ofthe bottom is derived chiefly from the cords, but in a lesserdegree from the bars C C also. The bar C" has hinged to its under side legs or stays F, which, engaging in racks G on the side rails, enable the stretcherframe to be supported, as in Fig. 3, for recumbent purposes.

j" are buttons to hold up the legs F when out ol' use. 4

d are straps or loops, which hook over studs e, so as to hold down the frame when dressing the bed, after which they can be again detached.

Should the vstretcher O O' C become bent or warped by use, its construction enables it to be readily reversed, when it will he better than ever.

Sacking may replace the cords; but I prefer the latter.

The cords being stretched lengthwise, the Y bed has no tendency to sink toward the center, Q as with cross-cording, and is as elastic at the side as at the middle. By simply drawing tight or slackening the cord at one end the re- I C. As a bushing-couch for a baby it is perfeet. At a very small expense this arrangementcan be adapted to any ordinary bedstead. /Vhat I claim as new, and desire to secure by Letters Patent, ist l. The arrangement ot' the stretcher-frame C O C and rails B and D, secured and supported as described, for the purpose set foi-tn. 2. The supportinglegs or stays Fand racks G, in the described .combination with the stretcher-frame C CC", for the purpose set forth.

.3. The described arrangement of straps d and knobs c, for the purpose explained.

In testimony of which invention I hereunto Set my hand.

ISAAC A. SERG-EANT.
