IMPROVEMENT IN BED-BOTTOMS.

The Schedule refer-'red to in these Letters Patent and making part of the same.

'To' all whom, tt may concern Be it known that I, EDWIN O. THOMPSON, ofthe city, county, aud-State of New York, have invented a certain new and useful Improvement in Springs for Bed-Bottoms, &c.; and the 'following -is hereby declared to be a full and correct description thereof.

My invention relates to a spring-bottom for beds, sofas, and other articles, the same'being made of two ranges or frames of slats, the slats of one range passing between and alternating' with those of the other range, and standing at an inclination to each other so as to be interlocked and held in position by means of cross-bars attached to the ranges of slats near their points of intersection.

These cross-bars keep the respective ends` of the ranges of slats separated from each other, to forni spring sections between said cross-bars and the ends of the slats,` and the central portion of the slats, where the greatest strength is required is very strong and at the same time yielding.

The mattress-padding or4 bedding may be placed upon the spring-bottom thus formed, or upon a separate range of slats' resting at their ends upon the said spring-bottom.

In the drawing- Figure 1 is a longitudinal section oi' my improved spring;

E igure 2 is a cross-section of the same at the line :c x, fig. l;

Figure 3 isa plan of said spring; and

Figure 4 is a sectional view illustrating the manner in which the spring may be folded for transportation.

a a represent the slats forming one range, and

b b are the slats of the other range.

These slats may beA either of wood or metal, and are to be provided with cross-slats c d at either or both of their ends.

'lhe slats w of one range pass between the slats b of the other range, and they take a bearing upon or are caused to interlock with each other by means oi' the cross-bars or bearers h h, which I have shown as attached to the slats a a, but said bearers might be 1 attached one to .the slats a and the other to the slats b.

rIhe ranges of slats a and b cross each other diagonally, andthe cross-bars lt lt keep the respective ends of the ranges oi' slats a b apart from each other, to form spring-sections between said cross-bars and the respective ends of the slats, and said spring-sections may be made more or-less yielding by placing the cross-bars h 'h nearer to or further from each other.

'lhe cross-slats c d rest upon bearers i t' in the bedstead, as usual, and I remark that these slats c d may be dispensed with upon one end of each of the ranges of slats a b, so that the same can be separated from cach other to facilitate packing for transportation.

The spring-slats above described may be used as a bed-bottom without the use of' the range of slats l, shown in iig. 1, but this range of' slats l may be em- -ployed when desired, and byits use the mattress and bedding can be kept in better .position when not in use, and a more nearly horizontal bed-bottom will be provided.

I have shown said slats l as resting upon the ends of the spring-slats a b, and connected at their ends by the cross-slats m m.

Vhen the slats a b are provided with the crossslats c c d d, as shown in iig. 1, the spring can be turned to the position shown in g. 4, to reduce it to a small compass for transportation.

1. The intersecting slats a l), crossing each other at an inclination, and kept in position by the cross-slats h, so as to form spring-sections for a bed-bottom or other article, substantially as set'forth.

2 111 combination 4with the foregoing parts, the

eparate frame of slats Z, as and for the purposes set orth.

Signed'by me this 5th day of DecembcnA. D. 1870.
