SPRING BED-BOTTOM.

l SPECIFICATION forming part of Letters Patent No. 240,568, dated April 26, 1881.

" Application filed November 8, 1879.

Improvements in Spring Bed-Bottoms, of

which the following, in connection with the accompanying drawings, forming a part hereof, is a ful1,cIear, and exact description, which Will enable others skilled in the art to which ro myinvention appertains to make my improvements and apply them to use.

` In the drawings, Figure l is a top or plan view of a bed-bottom embodying my improvements; Fig. 2,'a verticalcentral cross-section `1.5 thereof 5 Fig. 3, a bottom vienT thereof when the Woven-Wire mattress is removed, and Fig.

4 a perspective of one of the spiral springs.

Like letters of reference indicate like parts. A A represent the side rails, and B B the zo. end rails.

C C are corner-plates for connecting the end rails and side rails together at the ends, so as to form a frame,`the end rails being supported above the side rails, as shown, and as f. is common in frames adapted to receive a Woven-wire mattress. Y

D is a Woven-wire mattress, stretched from `)one end rail to the other and rmly applied to each.

" 3o E E are intersecting cross-bars arranged below the mattress D, and connected to the Side rails and end rails, respectively, by means y f thespiralisprings F F.

G G are tapering spiral springs, the small ends of Which rest upon the bars E E, and the large or upper ends of which support the mattress D. I deem it best, for the purpose of connecting the springs G G to the mattress With facility, to bend the upper coil of each spring into an eye, a., and to Weave that coil through the coils of the mattress, and to tie or secure the end of each coil by passing it through the eye a, as indicated in Figs. 2 and 4. By this means the elasticity oi' the mattress is greatly increased, and any ordinary slackage will not be noticeable, the mattress being supported on the springs G G, and they, in turn, resting on the slats E E, which are rendered yielding by means of the springF F.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A spring bed-bottom consisting of the combinationof the rails A and B, the corner-plates C C, t/he Woven-Wirefmattress D, the crossbars E E, the springs F F, and the springs GG, all arranged and operating together substantially as described, and for the purposes set forth.

EDWARD YEOMAN.
