JAMES B. RYAN, OF NEW` YORK, N. Y., ASSIGNOR TO THE NEW YORK VOVEN VIRE MATTRESS COMPANY, OF SAME PLACE.

BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 599,739, dated March 1, 1898.

Application led July 21, 1897. Serial No. 645,397. (No model.) v

To @ZZ whom, t may concern:

Be it known that I, J AMES 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 anduseful 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 that class of bedbottoms which embody woven wire mat# tresses; and it contemplates providing such a bed-bottom with cheap, simple, and efficient means for imparting extra strength to and holding the mattress under tension, so as to prevent undue sagging of the same at the center.

The invention will be fully understood from the following description and claims when taken in conjunction with the annexed drawn, ings, in which- Figure l is a plan View of a bed-bottom embodyin g my invention with the mattress partly broken away. Fig. 2 is a detail transverse section taken in the plane indicated by the line x of Fig. l. Figs. 3 and 4t are detail plan views of modifications, and Fig. 5 is a detail plan view of a modification with the mattres partly broken away.

. Referring by letter to the said drawings, and more particularly to Figs. l and 2 thereof, A indicates the frame of the bed-bottom, which is preferably of the ordinaryrectangnlar form and construction.

B indicates the mattress of woven-wire fabric, which is also of the ordinary construction and is connected to thefend bars a of the frame, and O indicates resilient rods, which are preferably of wire,as shown. These rods C are disposed transverse of the bed-bottom at opposite sides of the middle thereof, and they extend through the meshes of the wire mattress and are thereby secured to the same, as illustrated. To-these rods C, I connect the ends of one or more (preferably three) helical springs D, which are disposed longitudinally below thefabricand between the said rods O, and are preferably provided with hooks b lto permit of their ready connection to the latter. These springs D are stretched and lplaced in engagement with the transverse rods C under tension, and in consequence it will be observed that they will hold the fabric B under tension and increase the strength and rigidity of the same, so as to prevent the undue sagging at the center, which is the common obj ection to woven-wire mattresses. The

said springs D increase the tension of the mat- I prefer to employ the rods C, because they materially increase the efficiency of the springs D. `I do not desire, however, to be understood as confining myself to the same, as the springs may be connected with the mattress through the'medium of rings O', (see Fig. 3,) or their hook ends b may be placed in direct engagement with the wire of the mattress, as illustrated in Fig. 4L.

In Fig. 5 of the drawings I have illustrated a modification in which a middle transverse bar E is disposed transversely below the mattress B, free from connection therewith at its ends, and two transverse series of longitudinally-disposed springs D are employed, said springs being interposed between the middle bar E and rods C and connected at their ends to the same, as shown.y

While this construction operates to further distribute the weight of a person lying on the mattress upon the several springs and to strengthen and prevent undue sagging of the mattress, yet the construction shown in Fig.

lis preferred because of its simplicity and cheapness. It will be appreciated from the foregoing that all of the embodiments of my invention are exceedingly cheap and simple and are adapted to be quickly and easily applied to a mattress. It will also be observed that the mattress may be placed under more or less tension and thereby rendered more or less stiffer rigid by stretching the springs to a greater or less extent prior to connecting their ends with the mattress.

Having thus described my invention, what I claim isl. A bed-bottom comprising a frame, a mattress of woven-wire fabric attached to the frame, and one `or more horizontal, helical springs arranged below and parallel to the mattress; the said springs having their ends connectedto the fabric forming the mattress at intermediate points in the length of the same, and being stretched or under tension, whereby they are supported by the mattress and are adapted to prevent sagging of the same, substantially as specied.

2. A bed-bottom comprisingaframe, a mattress of Woven-wire fabric attached to the same, and the transverse, resilient rods and a series of horizontal, helical springs carried by the fabric forming the mattress; the said rods being disposed at opposite sides of the middle of the bed-bottom and between said middle and the ends andthe springs heilig stretched or under tension and arranged below and parallel to the mattress and extend ing in the direction of the length of the bedbottom between the transverse rods and having their ends connected to said rods, substantially as specified.

3. A bed-bottom comprising a frame, a woven-wire mattress or fabric attached to the frame, transverse resilient rods extending through the mesh of the fabric and disposed at opposite sides of the middle of the bottom, a resilient transverse bar arranged between said rods and below the mattress or fabric, and transverse series of longitudinally-disposed springs arranged below the mattress or fabric and connecting the resilient bar with the resilient rods, substantially as specified.

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

JAMES B. RYAN.
