BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 614,987, dated November 29, 1898. Application filed November 17,1897. Serial No. 658,853. (No model.)

T0 at whom it may concern.-

Be it known that I, JAMES B. RYAN,a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bed-Bottoms; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the so called double-decked spiral-spring bed-bottoms; and it consists generally in such a bed-bottom comprising a suitable base, a lower horizontal series of vertically disposed spiral springs, preferably of helical form, connected to and rising from the base, an upper horizontal series of vertically disposed spiral springs, preferably of double helical form, which are separate from the lower series and have their upper ends suitably connected together, and a flexible horizontal fabric of woven, laced, or linked wire interposed between the lower and upper series of springs and suitably connected to the contiguous ends thereof,the said fabric being adapted to steady and effectually prevent the lower and upper series of springs from moving laterally or wabbling when weight is imposed upon the bottom and being also adapted to permit each of the lower springs to give independent of the springs around it when weight is imposed on the particular spring or springs above it, which contributes materially to the springiness, and consequently to the ease, of the bottom.

The invention also consists in the construction hereinafter described, and particularly pointed out in the claims appended.

In the accompanying drawings, Figure 1 is a plan View of myimproved bed-bottom in its operative position with parts broken away. Fig. 2 isatransverse section of the same, and Fig. 3 is a detail section.

I prefer in practice to have my improved bed-bottom comprise two sections A, which are connected in a hinged manner at B, so as to permit of it being folded upon itself in the ordinary manner for convenience in shipping or transportation. I do not desire, however, to be understood as confining myself to the embodiment of the invention in a folding bottom, and will therefore describe the same in terms sufficiently broad to cover the bottom when formed in one section and also when formed in two or more sections.

O designates the base of the bottom, which may be of any suitable construction, although I prefer to form it of connected metal straps a, as shown.

D designates the lower horizontal series of vertically-disposed coiled springs, which are preferably increased in diameter from their lower to their upper ends and have their lower ends connected to the base O, preferably by being passed through apertures l) in the straps a, as shown.

E designates the upper horizontal series of vertically-disposed helical springs, which are preferably increased in diameter from their middles to their opposite ends and are by preference so arranged that each one will bear upon the upper end of one or two of the lower springs D.

F designates the preferred connection for the upper ends of the springs E, which is a mat or cover formed of woven-wire fabric and arranged upon and connected to the upper ends of the springs E and also arranged in a frame G, of metallic rods or other suitable material; and II designates the continuous fabric of woven, laced, or linked wire, (preferably woven wire,) which is interposed between the lower and upper series of springs D E and has its meshes arranged to receive the contiguous ends of said springs, as shown, so as to securely connect it to the same. As will be readily observed, the fabric II forms a yielding platform interposed between and connected with the lower and upper series of springs and adapted to support the upper springs, whether the same are arranged in vertical alinement with the lower springs or not. This interposed flexible fabric H is preferably arranged in a frame I, of metallic rods similar to that inclosing the mat F, and in addition to forming a support for the upper springs E it has for its purpose to steady both lower and upper springs D E and effectually prevent the same from moving laterally or wabbling when weight is imposed upon the bottom, which is the chief objection of those spiral springs which extend the full height of a double-decked bottom and are tied together at their middles. \Vhile performing the functions just stated in an efficient manner, the fabric II permits each of the lower springs D to give independent of the springs around it when weight is imposed on the particular spring or springs above it, and thus contributes materially to the springiness and ease of the bottom and renders the same greatly superior to those bottoms in which a rigid frame, of wood or other material, is interposed between lower and upper horizontal series of springs, with the result that when weight is imposed on one of the upper springs it is distributed among several of the lower springs, which detracts from the springiness of the bottom.

As best shown in Fig. 2, the mat F is by preference connected to the upper ends of the springs E in the same manner that the fabric ll is connected to the springs D E-i. 6., by having its meshes arranged to receive the upper ends of said springs E.

The fabric II and mat F are preferably provided with strap stays c, which extend through their meshes and are connected to their frame rods. Said fabric and mat are also preferably made of a greater width than the base 0, so as to overhang said base, as shown, and adapt the bottom for use on metallic bedsteads. Vhen, however, the bottoms are to be used on wooden bedsteads, the base 0, fabric H, and mat F will be made equal in width.

It will be appreciated from the foregoing that I have provided a high or double-decked mattress which while possessing the advantages stated is very simple and may be quickly and easily made entirely of metal, if desired.

Having thus described my invention, what I claim is 1. The herein-described double-deck bedbottom comprising a suitable base, the lower horizontal series of vertically-disposed spiral springs connected to and rising from the base, the upper horizontal series of verticallydisposed spiral springs, the flexible wire fabric H arranged between and connected to the adjacent ends of the lower and upper springs and forming a yielding support or platform for the upper springs so as to permit of said springs being arranged in or out of alinement with the lower springs, and a suitable means for connecting the upper ends of the springs comprised in the upper horizontal series, substantially as specified.

The herein-described bed-bottom comprising the base, the lower horizontally-disposed series of vertical springs connected to and rising from the base, the upper horizontally-disposed series of vertical springs, the woven-wire mat arranged in a marginal frame G and having its meshes receiving the upper ends of the upper springs whereby it is connected of itself to the same, and the woven-wire fabric 11 arranged in a marginal frame I and interposed between the lower and upper series of springs so as to form a platform or support for the upper springs and having its meshes receiving the contiguous ends of the lower and upper springs whereby it is connected of itself to the same, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
