BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 770,090, dated September 13, 1904,

Application filed May 6, 1904. Serial No. 206,736. (No model.)

To all whom, it may concern.-

Be it known that I, NIcHoLAs R. MURPHY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Bed-Bottoms, of which the following is a specification.

My invention pertains to bed-bottoms, more particularly bed-bottoms of fabric and spring supports; and it has for its object to provide a bed-bottom having a resilient fabric support which is calculated to prevent undue sagging of the fabric, especially the center thereof, and at the same time lend strength and durability to the fabric without lessening the resiliency of the bottom, but rather increasing the same. 7

With the foregoing in mind the invention will be fully understood from the following description and claims, when taken in connection with the accompanying drawings, forming part of this specification, in which- Figure l is an inverted plan view of the bed-bottom constituting the present and preferred embodiment of my invention with the major portion of the fabric broken away, and Fig. 2 is a detail transverse section taken in the plane indicated by the line 2 2 of Fig. 1 looking in the direction of the arrow.

Similar letters of reference design ate corresponding parts in both viewsof the drawings.

The frame of my novel bed-bottom may be of any construction compatible with the purposes of my invention; but I prefer to have it comprise sidebars A and end bars B, fixed with respect to the side bars and disposed in a horizontal plane above the intermediate portions of said side bars. The fabric C, which is interposed between and connected to the end bars B of the frame in the usual manner, is preferably a woven-wire fabric of one or more thicknesses, although any other fabric suitable to the purposes of my invention may be employed without involving a departure from the scope of the invention.

The fabric support D, in which my invention chiefly resides, is made up of the following instrumentalities, viz: an open preferably circular body a, of wrought-iron or other suitable material, which is preferably flat in cross-section and is disposed below the central portion of the fabric C, as shown in Fig. 2; crossed rods 6, preferably of wire, disposed within the open body a; coiled springs 0, which are interposed between and connected to the ends of the said rods 6 and the body a; rods d,

- preferably of wire, connected at their outer ends to the end bars B of the frame at intermediate points in the length of said end bars, and coiled springs 13, interposed between and connecting the inner ends of the rods d and the central open body a. The springs c and c are preferably expanded or under tension and are by preference of such size in crosssection'as to extend above the upper side of the body a, as shown in Fig. 2. In virtue of this construction it will be observed that while the body it affords a strong and durable support for the plurality of springs the springs alone contact with the fabric, and hence the fabric, particularly the central portion thereof, is supported and held against undue sagging in an .efiicient manner and without robbing the bottom of the desirable resiliency. On the other hand, it will be noticed that the several springs contribute very materially in rendering the bottom as a whole highly resilient. It will further be observed that the body (6, supported by the rods (Z and the springs a, and the rods 6 and springs 0, arranged in and supported by the said body a, lend strength and durability to the center of the fabric and render the bottom easy and comfortable at all points.

It will be appreciated from the foregoing that with all of its practical advantages my novel bed-bottom is as simple and inexpensive as the ordinary bed-bottoms extant.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exactunderstanding of the said embodiment. I do not desire, however, to be understood as confining myself to such specific construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a bed-bottom, the combination of a frame, fabric connected thereto, and a support for the fabric comprising an open body, rods connected at their outer ends to opposite bars of the frame, coiled springs interposed be tween and connecting the inner ends of said rods and the body, crossed rods arranged within the open body, and coiled springs interposed between and connected to the open body and the ends of the said crossed rods.

2. In a bed-bottom, the combination of a frame, fabric connected thereto, and asupport for the fabric comprising an open body which is fiat in cross-section, rods connected at their outer ends to opposite bars of the frame, coiled springs interposed between the inner ends of said rods and the open body and resting above the upper side of the body so as to hold the fabric off the same, crossed rods disposed within the body, and coiled springs interposed between and connecting the body and the ends of the crossed rods and resting above the upper side of the body so as to assist in holding the fabric off the same.

3. In a bed-bottom, the combination of a frame, fabric connected thereto, and a support for the fabric comprising an open body, coiled springs connected with said body and opposite bars of the frame and extending above the upper side of the body so as to hold the fabric off the same, and one or more coiled springs arranged within and connected with the open body and extending above the upper side of said body so as to assist in holding the fabric off the same.

L. In a bed-bottom, the combination of a frame, fabric connected thereto, and a support for the fabric comprising an open body, connections between said body and the frame, crossed rods arranged within the open body, and coiled springs interposed between and connected to the open body and the ends of the said crossed rods.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. v
