DAVID RENSHAW, OF BOSTON, MASSACHUSETTS, ASSIGNOR or ONE-THIRD TO EDWARD LALLY', OF SAME PLACE.

SPRING BED-BOTTOM.

SPECIFICATION forming" part of Letters Patent No. 271,517, dated January 30, 1883.

Application filed December 26, 1882. (No model.)

To all whom 2t may concern:

Be it known that I, DAVID RENSHAW, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Spring Bed-Bottolns;

and I do hereby declare that the following is a full. clear, and exact description of the invention, which will enable others skilled in the art to which it appertaii'is to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to certain new and useful improvements in springs especially designed for use in connection with the ordinary slats of bedsteads to form a spring bed-bottom; and the invention consists in novel features of construction and combination and arrangement of parts, as will be hereinafter fully (lescrihed, and specifically designated in the claims. Y

In the drawings, Figure l is a top or plan view of my improved bed-bottom. Fig.2 is a transverse section thereof; Fig. 3, a detached view of the spring.

The letter A designates the slats of the bedbottom, and B the springs. These springs are formed of pieces or strips of the best steel or brass, bent in the shape as shown in Fig. 2, and connected transversely from one slat to another, the ends being turned under the slat, as shown at b, and nailed, screwed, riveted, or otherwise secured thereto. A strip, G, is nailed to the bottom of the slats at each end, which Serves as a brace to the same and prevents them from wabbling. The slat at the middle of the bed-bottom is divided longitudinally, as shown, and the two parts hinged together at each end or in the center thereof, as indicated by the letters 0 c, which .enables the two halves of the bed to be folded back to back for transportation; or it can be so hinged at its middle portion to fold up top to top, as the Springs are so arranged to enable this to be done quite as readily as the other way. For instance, a row of springs being fastened along the slats, as described, the next row is so arranged as to bring them either to the right or the left of the former row, making them come between the same, and when the two halves of the bed are folded the springs, by being so arranged, will fit in the spaces thus created. The springs can be made of strips of steel, brass, or any material that is sufficiently elastic, from one to three inches wide, according to circumstances and bent in any suitable manner and by any suitable means.

A spring bed-bottom of this construction is particularly adapted to ease and comfort, the 6c springs all being of the same height and of the same elasticity, and hollowness or sinking down of any part of the bed avoided while 1ying thereon. Numbers of beds are already in 1 use to obviate these defects; but they do not 6 accomplish theobjectso well as in this instance.

The advantages of this form of spring-ale simplicity of construction, cheapness of first cost, and durability. They can be made by dies in much less time than is now consumed in making-springs for the same purpose, and they are so formed as to pack in small space in packages for commercial use and tor transpor; tation. Furthern'ime, these springs can be ap-- plied to any ordinary bed-slats by any person, but little ingenuity being necessary to fasten them between the slats, as shown, and the strips 0 0 applied or not, as may be desired.

\Vhat I claim is- .1. In a spring bed-bottom, the slats A, secured t0 the transverse strips U C, and being connected by the series of springs B, formed substantially as shown, and secured to the slats on the bottom thereof, said bed-bottom being hinged at its middle portion, whereby it can be folded together for transportation, substantially as specified.

2. As a new article of manufacture, a bedspring formed substantially as and in the manner set forth.

In testimony that I claim the foregoing as my own I hereunto affix my signature in presence of two witnesses.

DAVID RENSHAVV.
