BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 237,552, dated February 8, 1881.

Application filed November 10, 1879.

To all whom it may concern.-

Be it known that I, ISRAEL L. LANDIS, of Lancaster, in the county of Lancaster, and in the State of Pennsylvania, have invented certain new and useful Improvements in Bed-Bottoms; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of this specification.

My invention relates to certain improvements in the invention for which Letters Patent of the United States were granted to A. Iske, February 4, 1879, No. 212,009, for improvements in spring bed-bottoms, which invention consisted of a bed-bottom composed of two side rails connected by end rails and adjustable screws, and a series of springslats, with cross-bars interposed between the slats and side rails near each end; and the present invention consists in the combination,

with a bedstead, of a series of springslats sprung at opposite ends under cleats attached to the head and foot of thebed, respectively, and certain cross-bars extending under said slats, near each end, and adjustably mounted on ledges at the side rails, whereby the tension of the slats may be regulated, as more fully hereinafter specified.

1n the annexed drawings, Figure 1 is a longitudinal section of a bedstead embodying my invention, and Fig. 2 is a transverse section of the same.

The letter A indicates a bedstead of any suitable construction, and containing a series of longitudinal spring-slats, B. These slats are supported near each end on a cross-bar, O, which has its upper side made convex, as shown. The extreme ends of the slats B are sprung under cleats D D, fastened to the end pieces or head and foot of the bedstead. The cross-bars O G are supported upon ledges a a formed on the side rails of the bedstead, and under each end of each crossbar is a setscrew, F, passed upward through the ledge a. The set screws may screw directly through said ledges or through nuts I) embedded therein. By means of the set-screws F the crossbars 0 can be adjusted up and down, as required, to regulate the tension of the slats, or, in other words, to regulate their spring, so as to suit heavy or light persons.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination, with a bedstead, of the spring slats B, sprung at each end under the cleats 1), attached to the end pieces of the bedstead, and the cross-bars C, extending under said slats near each end, and adjustably sup ported uponledges a a formed on the side rails, whereby the tension of the slats may be regulated, substantially as specified.

In testimony that I-claim the foregoing I have hereunto set my hand this 8th day of November, 1879.

ISRAEL L. LANDIS.
