To all whom t'tmuty concern:`

Be it known that I, ELBRIDGE S. KIMBALL, of Springfield, in the county of Hampden, and State of lvlassaclmsetts, have made and invented anew and useful Improvement in Spring-Bed Bottoms; and I do hereby declare that the following is a full, clear, and exact description of the construction of the same, reference being had to the annexed drawings making a partof this specification, in which like Aletters mark like parts, and whereof- Figure 1 is a side elevation;

Figure 2, a plan;

Figure 3, a transverse section of the end of `the frame, coil-rod, and block; and

Figure 4, a detached side .elevation of one-half of a douhle coil-spring.

My invention relates to that class of spring-bed bottoms in which narre'vs1 slats, provided with loops or leathers, are connected at-each end with double-coil springs.

' To enable others skilled in the art to practice my invention, I describe the same as follows:

In the accompanying drawing- The part marked c representsthe side of the frame; b, the end thereof; in which are set the legs of the double-coil spring c c', the arms of which latter, d d', are connected by' a bar,.e e', from whichy projects a tongue, j; whereon is hooked the loop or leather g, connected with slat h, the whole spring being made of a single piece ot elastic wire.

Passed through the coils ot the several springs, and

to steady lthe same, is a rod, z, supported and held in f 'providingr the ba'r thereof', c e', with a tongue, f, projecting therefrom rearward and downward, thus constituting such har a rest or beariugfor the loop y; and

My invention consists in the lifter-spring thus peculiarlyformed, and in the combination of the same within thesuperiucumbent loop y; the objects thereof f being, by giving the Io'op g a rest or bearing on the bar e e', to prevent the tearing out of such loop, to protect the lmattress from'the spring, and to prevent the rocking and. swayinglof the slat, without the use of a double or folded loop or leather. Thus 'having described my improvement,

'hat I claim as new, and desire to secure by Letters Patent,l is

The double-coil lifter-spring c o', formed as at e e' f, in combination with the superincumbent Slat-loop g, all constructed and arranged iu the manner and' for the purpose specified.

E. S. KIMBALL.
