Definitions
- My present improvement designed to overcome this difculty, consists in constructing the springs in part of wood and in part of steel, the greater portion of their length being, as heretofore made, of wood, with terminal steel springs at either one or both ends.
- the side springs being intended to be in a similar manner connected to the side boards of a bedstead.
- the main portion C of the springs consists of a bar of hickory or other suitable tough wood; and in the example illustrated this bar of wood terminates at one end in a steel sprino, D, somewhat curved, as shown. Such steel bars may, however, be used at either end of the wooden portion of the spring.
- the springs are secured to the transverse bars B B, together with which and the wooden slats A, secured to the bars B, they constitute the bed-bottom.

Description
UNITED STATES PATENT FFICE.
JOHN HARPER, or HILLsRoRoUGH, IowA.
IMPROVEMENT IN BED-BOTTOMS.
Specification forming part of Letters Patent No. 153,075, dated July 14,1874; application tiled January 5, 1874.
tain the requisite amount of elasticity by means ofthe wooden springs without thinning them to such an extent that any unusual weight or shock was liable to break them.
- My present improvement, designed to overcome this difculty, consists in constructing the springs in part of wood and in part of steel, the greater portion of their length being, as heretofore made, of wood, with terminal steel springs at either one or both ends.
The annexed drawing represents, in perspective, my improved bed-bottom.
In general construction it v,is like the bedbottom covered by aforesaid Letters Patent,
the side springs being intended to be in a similar manner connected to the side boards of a bedstead. The main portion C of the springs consists of a bar of hickory or other suitable tough wood; and in the example illustrated this bar of wood terminates at one end in a steel sprino, D, somewhat curved, as shown. Such steel bars may, however, be used at either end of the wooden portion of the spring. Thus made, the springs are secured to the transverse bars B B, together with which and the wooden slats A, secured to the bars B, they constitute the bed-bottom. The slats A are arranged parallel to the side springs.
I am fully aware that it is very common to hang a bed-bottom on metallic springs at either end; and this I do not claim, of course. My invention consists of a combined wood and metal spring, forming the side bars of the frame of the bed-bottom proper.
What I claim, therefore, as my invention, and desire to secure by Letters Patent, is-
A bed-bottom composed of the combined wood and metal springs C D C D, transverse bars B B, and slats A, substantially as and for the purpose specified.
In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
JOHN HARPER.
