CHARLES JOHNSON, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN BED-BOTTOMS.
Specification forming part of Letters Patent No. 120,587, dated November 7, 1871.
To all whom it may concern:
Be it known that I, GHARLEs J oHNsoN, of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bed-Bottoms, of which the following is a full description, reference being had to the accompanying drawing making a part of this speciiication, in which- Figure l is a top Orplan view; Fig. 2, a vertical longitudinal section; Fig. 3, a detached view of the lower end of the spiral spring.
These improvements relate to an improved method of holding the spiral springs in position when they are removablyT attached to slats; to an improved mode of constructing and attaching the end springs; and in applying a covering connecting the same to the springs.
In the drawing, A represents head-and-foot boards or ends; B, the side rails; and C, the bottom slats of a bedstead of any ordinary construction; D, end springs; E, supporting-rods passing through the coils of the end springs; F, projections or hooks passing under the end slats; G, hooks or loops for holding the canvas or covering; H, spiral springs; I, projection or hook passing under the slat; J, side projection above the slat to prevent tipping ofthe spring; K, cross-rods at the ends to support the canvas or covering; L, canvas. The bedstead may be made in any of the forms where slats are used, but it is preferable to have the side rails of a width at least equal to the height of the springs H. The slats are applied in the usual manner. The springs H are also made in the usual manner, except at the lower end, at which point I rst form a horizontal projection, J, which locates the spring in the proper vertical position, and then carry out the wire and bend it around to come under the slat and spring at the central line of the spring, and then bend the wire around, as shown at I, Fig. 3, so as to form a considerable holding-surface below the slat. These parts I and J press against the slat C and hold the spring firmly in position, so that it will not tip in any direction. The springs D are made of heavy wire, and are coiled around the rod E,
when the ends F are bent so as to come below the slat and form, with the coil portion, a clamp to keep them in position. The upper end of this spring is formed into a loop, as shown at Fig. The canvas L is made t'o cover the entire bedbottom, and is looped at the ends. In these loops I place bars, K, which said bars are made of sufficient strength to bear the required weight when in use. In orde-r to insert them in the loops G I turn them under, so that the outer edge will be the upper edge when placed in position, as shown at Fig. 2. By these means the cover can be strained so tightly as to operate without the springs H; but I prefer to use them in connection with such springs, as I can thereby give the bed more elasticity. This covering can be easily removed for the purpose of cleaning, and it prevents the springs from unduly wearing the mattress or other bed-clothing placed upon this bottom. The springs H are placed in any desired position, and any desired number of them can be used. I increase the number where the greatest weight comes, and diminish them toward the foot of the bed, thus making a complete bedbottom, which can readily be applied to any ordinary slatted bedstead without changing its parts, and without any special tting.
I do not claim, broadly, the mode of attaching springs to slats by bending a portion so as to come below the slat; buty What I claim as new is as follows:
l. The springs H when provided with a projection, J, and the lower end I curved so as to form a lateral support to prevent tipping, substantially as specified.
2. The springs D, when provided at the lower end with loops or hooks F and at the upper end with the loop or 4hook Gr, substantially as and for the purpose specified.
3. The combination of the springs D with the bar or rod K and cover L, substantially as and for the purpose described.
