UNITED STATES WARREN JONES, O F BERLIN, WISCONSIN.

IMPROVED BED-BOTTOM.

Specification forming part of Letters Patent No. 54,737, datedMay 15, 1866.

To all 'whom it may concern:

Be it known that I, WARREN J oNEs, ot' Berlin, in the county of Green Lake and State of Wisconsin, have invented a new and useful Improvement in Spring Bed-Bottoms; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same, suiiicient to enable one skilled in the art to which it apperta-ins to fully understand and use the same, reference being had to the accompanying drawings, which are made part of this specification, andin which- Figure 1 is a plan of a bedstead-bottom, illustrating my invention. Fig. 2 is a side elevation of the same.

Similar letters of reference indicate corresponding parts in the two gures.

The nature ot' my invention consists in the employment ot' braces which, in addition to their function of preventing the deiiection or displacement of the spiral springs, are adapted in themselves to constitute yielding supports, so that, Whilev they lill an important ofce in conjunction with the springs, they have the special and independent character of elastic yielding bearings.

A A Al A2 A3 represent the under frame of the bed-bottom, which may be formed of longitudinal and transverse bars rigidly connected together, or be constructed in any other suitable manner. This frame supports the spiral springs which sustain the slats B, and the springs are, by preference, arranged in three transverse rows or series, G C C2, so as to sustain the slats at both ends and at the center.

D D are transverse bars interposed between the springs C C2 and the ends of the slats. The slots b, which embrace the attaching pins or studs d, admit of the requisite longitudinal play of the slats when they are deflected.

E E are braces ot' wood or metal, each which is attached to one of the bars D and the central bar, A2, of the under frame-wor They may occupy any suitable positions rel tively to the slats B and serve to prevent ai horizontal motion, laterally or longitudinali of the bars D when the weight of the pers devolves upon the slats.` Hence the sprin C G' C, being attached to the bars D, a always retained in upright positions, eXpan ing and contracting vertically without und( going any lateral or horizontal deiiectiou displacement. I

The braces E are made o't a suitable ela material, so that they shall yield and sprii vertically and thus assist in giving elastici to the slats. Having an elastic and sustai 'ing character in themselves the spring-brac E may be used independently of the spil springs it" desired; and I will here state th I do not wish to be understood as restrictii their application to bed-bottoms, as it may found practicable to apply them to other z ticles oi' furniture for all analogous purpos with a like beneficial result.

The straps F, which pass over the end ba D, and are attached to the frame beneath, ser to confine the bars in the desired proximi with the frame.

Having thus described my invention, t following is what I claim as new and des to secure by Letters Patent:

The combination of the braces E witlit springs C C' C2, slat B, bars D, and fran the whole being arranged to operate subst: tially in the manner and for the purpose: forth.
