UNITED STATES PATENT OFFICE,
FRANK J. ROBISSON, OF PETERSBURG, ILLINOIS, ASSIGNOR OF ONE-HALF TO D. M. BONE, OF SAME PLACE.
BED-BOTTOM.
SPECIFICATION forming part of Letters Patent No. 296,708, dated April 8, 1884.
Application filed September 8, 1881}. (No model.)
To all whom it may concern:
Be it known that I, FRANK J. Ron'rnson, of Petersburg, in the county of Menard and State of Illinois, have invented an Improved Bed-Bottom; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, making part of this specification, and representing a top View of my improved bedbottom.
In the drawing, A A represent a set of bed springs in place, and B B the slats on which they rest. The arrangement of these parts is as usual or as desired, and the outer springs are secured to a rim or border-band, 0, made of rattan, as shown; or the border-springs may each be connected at the outer edge by coiled springs, with the sides and ends of the boxframe of the bed-bottom.
My improvement consists in the peculiar method of connecting the springs A A at the top diagonally by means of two spiral springs, D D, each bent in the middle into a V form, as shown, and the two simply looped together, as at a. The spring portions of each spring are at the two ends, and between these two spring or coiled portions there is a singlewire connection at a, forming the apex of the V-shaped entire spring, sufficient in length to loop freely with the adjacent spring. Each of these springs is connected at its ends to two adjacent springs, A A, and the two springs looped together thus connect four adjacent bedsprings. Additional pairs of looped springs connect to every four adjacent springs in a row across the bed-bottom, and parallel rows are thus formed to compose the whole bedbottom. By this connection diagonally between the bed-spri-ngs, free joints are formed in line along the loop-connections a a, rendero ing this bed-bottom especially elastic and fieXible, and giving every bed-spring perfect free- .dom, each independent of all the others,while the bedsprings are all held in proper and upright positions, and when these free joints run 5 parallel with the supporting-slats a folding bed may be readily formed thereby. For smaller and cheaper beds, these diagonally-an ranged looped springs are a sufficient connection for the bed-springs; but for the largest and best beds I add spiral springs E E, to connect the bed-springs, at their nearest points, in directions both lengthwise and crosswise of the bed-bottom.
I claim as my invention In a bed-bottom, the V-shaped springs D D, each consisting of two coiled portions united by a single wire, forming the apex of the spring, looped together in pairs at their apices, in combination with the bed-springs 60 A A, and means for supporting the said bedsprings, substantially as and for the purpose herein specified.
The foregoing specification signed by me this 27th day of August, 1883. V
FRANK J. ROBINSON.
