Description
A.. TUBNBULL. Bed-Bottoms.
UNITED STATES PATENT OFFICE.
ANDREW TUENBULL, OF NEW BRITAIN, CONNECTICUT, AssIeNOE To THE NATIONAL WIRE-MATTRESS COMPANY, OE sAME PLACE.
IMPROl/EM ENT 'IN BED-BOTTOMS.
Specification forming part of Letters Patent No. 137,511, dated April 1, 1573; application tiled November 22, 1872.
To all whom it may concern:
Be it known that I, ANDREW TURNBULL, of New Britain, in the county of Hartford and State of Connecticut, have invented a new Improvement in Spring Bed-Bottoms; and I do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marked thereou, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specitieation, and represents, in-
Figure 1, a side View showing the cross-bar in transverse section; Fig. 2, a top view; and in Flg. 3, a longitudinal section ou line w m.
This invention relates to an improvement in that class 0f spring bed-bottoms in which the springs are attached to a crossbar at the -head and foot 5 the object `being to adjust the springs to a greater or less tension. The invention consists in making one or both of the cross-bars adjustable in a support at the ends,
U, the cross-bar being preferably set above the side A, as seen in Fig. 1.. The support B is chambered out to receive the end of the bar G, as seen in Figs. 1 and 3, and through this chamber a longitudinal screw, D, is placed, passing through the bar C, a nut, a', set into the bar, iu which nut the screw works; therefore, by turning the screw D, the bar C will be drawn back or thrown forward, accordingly as the screw is turned. The bed-bottom attached to the cross-bars may be drawn up to the desired degree of tension by ieans of the screw, and that tension slackened at any time by the loosening of the screw.
By preference I form both ends in this manner, but the object will be accomplished by making 011e of the bars stationary and the other adjustable, in the rua-nner described.
I do not Wish to^be understood as broadly claimin g the arrangement of adjusting-screws for the purpose of adjusting the tension of the springs, as such I am aware is not new.
I claim as my invention- The cross-bar C of a bed-bottoni frame, each end arranged in a support, B, attached to the Y side A, and made adjustable in said support by means of a screw, D, substantially in the manner set forth. j
ANDREW TURNBULL.
