UNITED STATES PATENT OFFICE.

WM. A. N. LONG, OF FISHERVILLE, NEV HAMPSHIRE, ASSIGNOR TO J. B.y RAND, OF SAME PLAGE.

BED-FOUNDATION.

Specification of Letters Patent No. 31,850, dated March 26, 1861.

To all whom t may concern.'

Be it known that I, WILLIAM A. N. LONG, of Fisherville, in the county of Merrimack and State of New Hampshire, have invented a new and useful or Improved Spring Bed- Foundation; and I do hereby declare the same to be fully described in the following specilication and illustrated in the accompanying drawings, of which- Figure l, is a top View, Fig. 2 a side elevation, Fig. 3, a longitudinal section, and Fig. 4, a transverse section of a bedstead provided with my invention, the said transverse section being taken through the series of basket springs, and their conical bearers situated near one end of the bedstead.

The nature of my invention consists in a bed foundation made with basket springs, conical bearers, and slat supporters arranged and combined with,cross rails and slats applied to a bedstead substantially as hereinafter described. e

In the drawings A, exhibits a bedstead of what is termed the cottage pattern. Two transverse bars B, B, extend from one of the side rails, a, a to the other of such bedstead, and are properly secured thereto. To the lower side of each of the said bars, B, B, a series of conical or basket springs C, C, is fastened, the several springs of such series being arranged at equal distances apart. Each spring is constructed of wire coiled around in a heliX and soas to impart to the spring the conical or tapering form or basket sha-pe denoted in the drawings, the open end or mouth of each spring being placed against and fastened to the lower surface of the bar B, either by means of staples or their equivalents.

A conical or conoidal block of wood D, which I term va bearer is arranged within each spring and so as torest on the inner surface and bottom thereof.` A rod or slat supporter, E, projects upward from each bearer, D, passes loosely through the cross Abar, B, and terminates at its upper part in an eye, e, for the reception of one of a serles of slats F, F, arranged parallel to each other andV within the bedstead as eX- hibited in the drawings. Zhen necessary, each slat may be secured to `one of its two supporters by means of a staple, d, so arranged as to clasp the leyel -of the supporter and enter the edge of the slat. Each slat being upheld by two supporters sustained by conical bearers and basket springs arranged as set forth, is free to bend downward and operate as a spring when a inattress may be imposed on it.

The peculiar construction of the springs and their bearers and their arrangement with respect to the bedstead frame and the supporters of the slats are conducive to the production of a very elastic and easy bed foundation, one not liable to have its springs so injured by the strain to which they may be subjected as to become set A weight on the slats of the bed foundation, tends to elongate rather than contract the springs, and thus prevents them from becoming useless by setting Theconical bearers within the springs and separate from them, steady them and allow them to freely expand and contract. Besides, each bearer equalizes or distributes the bearing on the conical surfaces of its spring so as to prevent the spring from being broken by a sudden expansion of it.

I claim- The above described bed foundation made of the basket springs, slat supporters, and conical bearers, constructed, arranged and combined together and with the cross rails and slats of a'bedstead substantially in manner as specied.
