BED-BOTTOM.`

SPECIFICATION forming' part 0f Letters Patent NO. 599,736, dated March l, 1898. Application filed April 2l, 1897. Serial No, 633,173. (No model.)

To aZZ 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 I vo 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 bed-bottoms, and will be lfully understood from the following description and claims when taken in conjunction with the annexed drawings, in which- Figure lis a plan view of my improved bedbottom with the fabric partly broken away. Fig. 2 is a similar View of a modification. Fig. 3 is a detail plan view illustrating the manner in which the slack of the cables is taken up, and Figs. 4 and 5 are detail views of modied connections for the,'supporting-cables.

Referring by letter to said drawings, and more particularly to Fig. l thereof, A designates the frame Of the bed-bottom, which comprises end bars a and side bars b; B designates a mattress or fabric which rests over and is connected to the frame in the ordinary or any suitable manner, and G D designate V-shaped loops which serve to support the fabric B, so as to prevent undue sagging or sinking of the same, and thereby prolong its usefulness. These loops C D are formed of resilient spirally-coiled-wire cables for a purpose presently described.

The cables forming loops C are connected at their ends to the corners of the frame A, preferably to the ends of frame-bars a, and cross or intersect each other, so that their inner portions describe a diamond-shaped iigure, as illustrated in Fig. l. Said cables forming the loops C are also connected at their middles tO hooksr c at one end of tensionsprings F, which springs are connected with the frame-bars d, preferably through the medium of metal straps E, as shown.

The cables forming the loops D are shorter than those forming the loops C and are connected at their ends to the frame-bars a at points intermediate of the ends and middle thereof and have their middles, which extend within the diamond described by the loops O,

connected by a tension-spring G, the said spring being preferably provided with hooks d at its ends to engage the cable, as shown.

The cables forming the loops C D serve to efficiently support the mattress at all points and yet preserve to the same all its elasticity. This' is due to the fact that being formed of resilient spirally-coiled wire said cables possess'endwise elasticity and will therefore eX- 6o p of coiledwire cables is also materially advantageous for the reason that when it is desired to stiften the support or take up lost tension or slack the same may be readily accomplished by twisting the cables after disengaging them from the hooks of the springs or, in the case of the cables forming loops C, by disconnecting the springs from the straps E. After the cables` are thus shortened they may again be readily connected in the manner 8o shown in Fig. 3, as is obvious.

When a bed-bottom of less rigidity than that embodyingthe support shown in Fig. lis desired, the loops D and their connectingspring G may be omitted, as shown in Fig. 2.

When it is desired to increase the rigidity Orstiftness of the bed-bottom, especially at Y the center thereof, the spring G may be omitted and a link G (see Fig. 4) or ring G2 (see Fig. 5) employed for connecting the loops D, 9o the link G being preferable to the ring for the reasons before stated.

Having thus described my invention, what I claim is l. In a bed-bottom, the combination of the frame,the mattress connected to and arranged upon the frame, and the support for the Inattress disposed below the same and comprising` the loops C, formed by cables of resilient spirally-coiled wire said cables being connected roo at ltheir ends to the frame at or adjacent to the corners thereof and crossing or intersecting each other so as to describe a diamond-shaped ligure at the center of the bottom, coiled tension-springs connected at one end with the cables formingr the loops C, at the middle thereof and having their opposite ends connected with the end bars of the frame, the loops D7 disposed below the loops C, and formed by the comparatively short cables of resilient spirally-coiled wire; said cables being connected at their ends to the end bars of the frame and intersecting the cables forming the loops C,

- and a centrally-located connection between the niiddles of the cables forming the loops D, substantially as specified.

2. The combination with the frame and the woven-wire fabric secu red. thereon of the cables of spirally-coile'd wire secured at their ends to theend bars of the frame and looped one over the other in a longitudinal direction to form a diamond-shaped figure, and the tensionsprings secured at one end to said end bars and detachably taking into the bight of the cables7 whereby said cables may be detached and twisted to take up slack, substantially as specified.

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

JAMES B. RYAN.
