IMPROVEMENT IN BED-BOTTOMS.

Specification forming partof Letters Patent No. 140,387, dated July 1, 1873; application filed February 5, 1873.

To all whom it may concern:

Be it known that I, EDMUND W. QUINGY,

.of the city ot' Peoria, in the county of Peoria and State of Illinois, have invented an Improvement in Bed-Bottoms, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings making a part ot' this specification, in which like letters of reference refer to like parts, and in which- Figure l represents an end elevation; Fig. 2, a plan; Fig. 3, elevation of end ot bedbottom and rubber cylinder.

This invention consists ot' a square frame, composed of four pieces of wood, two of which lie longitudinally upon the others, forming the sides ofthe bottom. The pieces on which the latter rest are placed not far from the ends ofthe bottom, and are scre'wed or otherwise attached to the side pieces, and have each small blocks tixed along their ,upper surfaces to form recesses for the reception of the slats. They rest at each end upon a rubber cylinder or roller, whose axes are parallel with the length of the frame or bed-bottom, and are each about two and one-half inches in diameterbyabout twoinchesin length, with a bore 7 of about one inch in diameter, and are fastened to the end pieces by metal straps in such a manner as to allow them to be turned round from time to time to compensate for wear.

The drawing represents the bed-bottom in one of the best forms in which I construct it. A A are the transverse beams which support the slats B B, &c.; the side slats Bl B being permanently fixed to the ends of the beams A A,

and `provided on their upper surface with the small blocks a a., &c., to form recesses for the slats B B, Sto. C C are rubber rollers or cylinders, there being one of these placed under the end of each cross-beamV A A, the axes of the cylinders being in a line with slats B B, &c. These areV secured Vthrough their centers by metal straps b b, &c., (though not preventing them from being turned round when wear takes place,) to the cross-beams A A, in such a manner that the cylinders can be turned more or less within the straps b, but still elastically supporting the weight of the bed-bottom and superimposed bed, &c. The rollers C C, &c., each rest upon the horizontal bedstead-fraxne shown in the dotted lines.

The operation ot' this invention is as follows: The cylinders C C, &c., form an elastic support for the bed and bottom, each of which can be turned within its respective retaining-straps b b, &c., (when in any Way, or by constant pressure, they become abraded or worm) so as to present a new and uninjured part for use and support.

Vhat I claim as my invention isrIhe construction and arrangement of the frame A A B B', slats B B, &c., blocks a a, Src., straps b b b b, dto., and rubber cylinders C U, Smc., at corner of the frame, as described.

In testimony that I claim the foregoing bedbottom, I have hereunto set my hand this 22d day of January, 1873.
