SPECIFICATION forming part of Letters Patent No. 392,529, dated November G, 1888.

Application tiled July 7, lSS. Serial No. 279,281. (No model.)

To all whom, t may concern.-

Be it known that I, EDWIN F. TlLLEY, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Spring Bed-Bottom, of which the following is a full, clear, and exact description.

My invention relates to spring bed-bottoms, and has for its object to provide an inexpensive, durable, andcomfortable structure of this character.

The invention consists in certain novel features of constructioninvolving combinations of parts including a main frame, a fabric stretched thereover, central lie-enforcing springs for said fabric, and a re-enforcing frame supported by the springs and underlying the central opposite edge portions of the fabric, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings,forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figurelisaplan view of thebed-bottom with the woven-Wire fabric thereof partly broken away. Fig. 2is a central vertical longitudinal section of the bed-bottom, taken on the line w a; in Fig. l. Fig. 3 is a vertical transverse section taken on the line y y in Fig. l. Fig. 4 is a detail plan view, in larger scale, of parts of the bed-frame and top fabric re-enforeing frame and an adjacent spring; and Fig. 5 is a detail vertical sectional elevation thereof.

The main outer frame, A, of the bed-bottom may have any ordinary or approved construction, and the top fabric, B, stretched thereover and fastened thereto at its opposite ends,

may be made of Woven wire, as shown in the drawings, or of canvas, or of any other snitable flexible material. My improvement relates particularly to the arrangement of the re-enforcing springs G at the center of the bedbottom with relation to a reent'orcing frame, D, and the fabric B, as next described.

The drawings sh ow three transverse rows of re-enforcing springs C, which are supported on cross bars or slats E, fixed to opposite side rails of the frame A. The springs shown are of ordinary tapering coil form, and the two outer rows of springs are preferably set large ends downward and the middle row is preferably set large ends upward, as most clearly shown in Fig. 2 of the drawings.

rPhe metal frame D is made preferably of ordinary band or strap iron, and the smaller ends of the two outside rows of springs C are secured to two opposite sides of the frame, either by rivets entering holes in the frame and eyes on the springs or by upbent ends of the springs passed through the frame-holes and upset or riveted at the top of the frame.

The central parts o1 the opposite sides of the bed-bottom fabric B are held to the ends of the frame D preferably by tie-wires b, which are rove or passed through the fabric and through holes d in the frame and are twisted at their ends. I prefer to connect or stay the tops of the end springs, (l, of the middle row of springs to the fabric B by the same tiewires, b, used to hold the fabric to the re-enforcing-frame D. The larger upper ends or coils of the middle row of springs C are connected together by transversely-ranging links F, and these middle springs are also connected to the bottom fabric, B, by the wires or cords c, all as clearly shown in the drawings.

It will be noticed that the top fabric re-enforcing frame, D, is supported by the outside rows of springs C entirely across the bed-bottom, and also preferably from the end springs ofthe inner row of springs, and that the end bars or parts of the frame D are thus yieldingly held by the springs and give effective support to the central side or edge parts of the bed fabric B and prevent undue sagging of these parts of the fabric,which is so liable to occur when they are not sufiiciently re-enforced. The frame D is preferably made thin enough to be quite flexible, so that it willyield with any one or more of the springs C by pressure on the bed-bottom to assure comfort of the occupants of the bed.

I consider the arrangement of the re-enforcing frame D, having side or head and foot portions held to the outer or head and foot rows of re-enforcing springs C, and also having end cross-bars or parts underlying the central side edges of the bottom fabric and preferably tied or connected thereto, as an important feature of my invention. The number of transverse rows of springs C may vary as the size of the bed-bottom may require, as but two rows or more than three rows maybe employed, and the opposite sides of the frame IOO l) will be fixed to the outer or head and foot rows of springs, and the end bars or parts of the frame will underlie the central edge parts of the bed-bottom fabric in any case, and the middle row or rows of springs will be set large end upward to facilitate connection or tying of them to the fabric B and to give effective support to said fabric and with the same desirable results hereinbefore mentioned and as will readily be understood.

I am aware that narrow metal plates or bars supported laterally under a bed-bottom fabric by springs mounted on cross-bars of a bedbottom frame have heretofore been used, and it is also an old practice to use continuous spiral or coil springs stretched between the ends of a bed-bottom frame and along each side of the bed-bottom fabric, to which the springs are connected at the center by wire or other ties. I am also aware that it is common to provide spring-tension side straps, cach of which is made in two parts connected at their outer ends to the end cross-bars of the bed-bottom frame and connected at their inner ends by a coiled or spiral spring which underlies the central edge part of the bed-bottom fabric, and it is also not new to use series of said spring-tension re-enforcing straps entirely across the bed-bottom fabric. My invention is readily distinguishable from all these constructions in that it embodies a rectangular or four-sided frame supported by or from the outer or head and foot lateral rows of springs arranged beneath the center of the bed-bottoni fabric, the side bars of said frame ranging along the central opposite edge portions of said fabric and independently of the end cross-bars of the bed-bottom frame. rlhis construction has material advantages over those last above mentioned in that it is simpler, cheaper, and more durable, and leaves the end parts of the bedbottom fabric more elastic, and the continuous side parts of my reenforcing frame give far more effective sup port to the central side parts of the bed-bottom fabric than longitudinal plates having springs in them or connected to them and underlying the center of the sides of the bed-bottom fabric.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, in a spring bed-bottom, and with a main frame and a woven wire or other fabric stretched between its ends, of two or more series of transversely-ranging springs supported under the center of the fabric and a continuous rectangular or foursided re-enforcing frame supported by or from the outer or head and foot transverse rows of springs and ranging along the central opposite edge portions of said fabric to prevent undue sagging thereof, substantially as herein set forth.

2.'The combination, in a spring bed-bottom, and with a main frame and a woven wire or other fabric stretched between its ends, of two or more series of transverselyranging springs supported under the center of the fabric and a continuous rectangular or foursided re-enforcing frame supported by or from the outer or head and foot transverse rows of springs and placed between the springs and the fabric and. underlying the central opposite edge portions of said fabric to'prevent undue sagging thereof, substantially as herein set forth.

3. The combination, in a spring bed-botn tom, and with a main frame and a woven wire or other fabric stretched between its ends, of transversely-ran ging rows of sprin gs supported under the center of the fabric, the outer or head and foot rows of springs being set smaller ends upward and the inner row or rows of springs set larger ends upward to directly support the fabric, and a continuous rectangular or four-sided re-enforcing frame supported by or from the tops of the outer or head and foot rows of springs and ranging along the central opposite edge portions of the fabric to prevent undue sagging thereof, substantially as herein set forth.

4. The combination, in a spring bed-bot tom, and with a main frame and a woven-wire or other fabric stretched between its ends, of transversely-rangingrowsofspringssupported under the center of the fabric, the outer or head and foot rows of springs being set smaller ends upward and the inner row or rows of springs set larger ends upward to directly support the fabric, and a continuous rectangular or four-sided re-enforcing frame connected to the head and foot rows of springs and underlying and connected to the central opposite edge portions of the fabric, the inner springs being linked to each other and held to the fabric, substantially as herein set forth.
