IMPROVED SPRING-BED BOTTOM.

4 The Schdule referred to in these IlettersPatent and makingpart of the same.

To all persons to 'whom these presents may come,- h -Beit known that I, IRA Mos'HnR RUSSELL, of Lew` iston, of the county 'of Androscoggin, and State of Maine, have invented a new and useful Improvement in Springded Bottoms; and do hereby declare the same to beifully described in the following specification, and represented in the accompanying drawings,

of. wbch- 4 Figure l denotes atop' view of a springbed bottom `as provided with my invention, some ofthe slats being left off their springs, in order to exhibit thearrangement of the springs and thetransverse connectionbands.' 4

` Figure 2 is a longitudinal section, and

Jsignrel 3, a transverse section of the bed-bottom. In s uch drawingi .A-A-are two transverse rails, each,. at eaeh of its ends, being provided with a projection or pier, a, raised upon it. u

0n each of thesaid bars A Avis a series of frusto- -conical helical springs,1B; and there is vextended through the upper parts of the several springs of each series-that is, between the upper coil and the next y flexible bands, G C, each band, at its two ends, being' fixed to-the'two projectons ea of the bar A beneath it. The band, at the axis lof each spring, has a hole, b, made down throughit, to `receive o ne of two studs', c

c, which projectdownward from an elastic slat, D.

The said slat extends across the two series of springs,

and rests on two springs thereof, the pins or studs and the holes in the bands serving to keep the 'slat and the band in their proper positions relatively to each other and the springs.

There is to be a s lat, D, to each of the springs of' each series, it-being supported on tw'o springs, one

being of one, and the other being of the other series l of the springs.

Each pin or stud goes through the upper coil ofthe spring next belowit; add, as the said coil is between the leatherband and the Slat, it prevents the slat from WearingV the band. l

' The slat'sare readily removable from the bands and springs, and as easily put in place thereon.

I--make no claim to the combination of springs, bands,

v supporting-rails, and elastic slats; but

j 'I claim, as my invention or improvement- Y The arrangement of each ofthe bands O or C' with the spring B, the slats D, and the pins or studs c of' suh slats, such arrangement involving'the extension of the band through the several springs thereof, and v the pins or stads into the holes of the bond, in inauner substantially as and for the purpose as described.

IRA MOSHER RUSSELL.
