Letters Patent No. 90,229, dated May 18, 1869.

IMPROVED BRACE FOR SPRINGBEDS.

The Schedule referred to in these Letters Patent and makingl part of the same The object of my invention is to provide a means' for preventing any oscillation in spring-mattresses, more especially those known as the Kre'ighoi' patenti'ron spi'ing-niattress# and consists in providing metallic stays, or braces, constructed and arranged as will be hereinafter more fully explained.

It is well known to the manufacturer, and trade generally, that in all spring-beds, where spiral springs are used between two frames, the upper frame, when weight is applied, will oscillate in various directions, rendering the bed unsteady, and, in time, impairing the springs, and rendering the whole structure loose and noisy. I am aware that many attempts have been made to overcome these objections in springmattresses, but, so tin as l am able to judge, none have proved effectual. Y To enable those skilled in the art to make and understand my invention, I will proceed to describe the same, referring by letters to the accompanying drawings, in which- Figure 1 represents an end view of an iron springmattress, with my improved brace applied to the same;

Figure 2, a side view of the same; and

Figure 3, a perspective View oi' one of the braces.

Similar letters oi' reference denote like parts in the diierent figures.

A is the top frame, and B, the bottom frame, composed of sheet-metal bands, or strips, interwoven or crossed at right angles, the springs, O, being secured at the points of intersection of the bands, and lying between and holding apart the two said frames.

l) is the st-ay, or brace, which may be made of any suitable material, (metal.) I prefer to make them o' spring-bed wire. They are bent, as seen at e, g. 3, and formed with eyes at the two ends, and are applied to the bed in the followngmanner:

The loop, or bend e, is made to embrace one coil of the spring, and is then clamped thereon, the ends being forced apart and secured by rivets, through the eyes, fj, to the top and bottom outside bands,'or1strips of the frames. p

Of course the number is -not limited, it only being observed that the loopsre are always to be placed toward each other, the ends extending in the opposite direction. f.

It will now be seen, that when weight or pressure is appliedto the top of the mattress, itrwill spring vertically, andany tendency to oscillate is eectually prevented, by the action of the braces, t. e., resisting.

in opposite directions. The brace will bow, or spring, to accommodate itselfto the altered distance between the point of contact with the frame and the spring to which it is clamped, which results from the contraction and expansion of the springs. Having fully described the construction and operation of my improved brace, or stay,

What I claim as new, and desire to secure by Letters Patent, is

The brace D, clamped to the coil of the spring, at e, and secured to the upper and lower frames, by means of rivets, or their equivalent, passing through the eyes ff, substantially as shown, for the purpose set forth. In testimony whereof,1 have hereunto set myhand and aiiixed my seal, this 10th day of April,.A. D. 1869. Witnesses: H. D. BOLT. [L 8.]
