PATENT BED.

SPECIFICATION forming part of Letters Patent No. 790, 720, dated May 23, 1905.

Application filed September 12, 1903. Serial No. 172,958.

To all whom it may concern: Beitknown that we,WVILLIAM C. BURDETTE and HIRAM H. MALoNe, citizens of the United States,and residents of Anderson, in the county of Madison and State of Indiana, have made a certain new and useful Invention in Beds; and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a plan view. Fig. 2 is a perspective view of the frame portion. Fig. 3 is a detail view on line 3 3 of Fig. 1.

The invention relates to spring bed-bottoms; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, the letters a and a designate the head and foot sections of a bedstead having the joint-lugs (0 provided with the seats (0 To these are connected the side rails I) b by means of the catch projections b of their joint ends, which engage the seats (4 These side rails are made of angular form in cross-section, and they are connected near their joint ends by means of the elastic steel cross-bars b 72 These cross-bars are preferably of angle -steel and are of slightly-arched form, being about an inch higher in the center than at the ends. Their ends are slotted in order to facilitate their automatic adjustment when they are attached to the side rails by the bolts 0. The arch of these elastic cross-bars is designed to give them a form which allows movement under tne weight of persons sleeping thereon, the pressure bringing them into a more or less level position. It also serves to give a sort of crown or upward-rounded form to the bed when not in use, thereby adding to its appearance. The elasticity of the cross-bars may be aided and the bars, when made of thin steel, strengthened by attaching to them the short reinforcing-strips d of steel.

The cross-bars are braced in position relative to the sidebars by the oblique corner brace-bars 0. These bracebars are attached to the crossbars by rivets and to the side rails by means of bolts, these bolts passing through longitudinal slots of the brace-bars, whereby they are allowed a small amount of motion on the bolts when there is pressure on the bed-bottom, causing the arched cross-bars to become depressed, as hereinbefore described.

The side rails and cross-bars are provided with series of upward-projecting pins or studs g, having rounded or oval heads. These studs are set back from the edges of the bars near the outer wall or flange and serve as bearings for the bends or loops of the wire 20. This is a long single wire of strong Bessemer steel, which is secured by one end to a stud at one corner of the frame made by the side rails and cross-bars, is then passed backward and forward from end to end of the frame around the studs at the ends, and is finally secured to a pin at the corner of the frame on the opposite side. This wire is easily placed in position by using a supporting-frame about the -height of the bed-bottom. After the ends of the wire are secured the branches of the longitudinal loops are drawn laterally and across each other in a regular Zigzag fashion, whereby a triple bracing engagement is provided in the following manner: The branches of each loop are drawn laterally away from each other at one-quarter the length of the frame from each cross-bar and are then connected to the branches of the fourth loops in series at the sides thereof, crossing the branches of the two intermediate loops. Then the branches of the first loop are drawn reversely toward and across each other at the middle of the length of the frame, where they are connected to the branches of the adjacent loops on each side. In this way each longitudinal branch of the wire overlaps two ad jacent longitudinal branches to form a series of mutually-supporting large diamond-form figures and centrally within the same a series of small diamond-form figures. These connections are made by means of the short transverse coil-springs (indicated at 71;) in such wise that there will be three series of such transverse coil-spring connections-one across the middle of the bed-bottom and one half-way between this middle series and each end cross- I0 diamond forms overlapping in a triple man'- ner on each side and providing a substantial spring bed-bottom, which, while it has suflicient elasticity laterally, is not apt to sag between the ends. The elasticity isderi'ved from 5 lateral spring play rather than from yielding between the ends, so that the tendency to-sag between the ends is very much reduced, and

the zigzag branches being supported by each other in the triplemanner involved in the 0 overlapping diamond arrangement the bedbottom is laterally, as well: asv longitudinally, braced by the Wireitself and the transverse coil-springs are protected from, a bending strain and kept in: their plane of Work.

5 It will; be understood from the above clescription that the head and foot sections are- 3 connected by the bed-bottomz section, eonsisting of the side rails, braced cross-bars, and the Wire.

Having described the invention, what we claim, and desire to secure by Letters Patent,

The bed-bottom consisting of the studded side rails, the studded cross-bars attached: to

' said side rails, and the single wire embracing the studs of the side rails and cross-bars and arranged in longitudinal Zigzag branches each said longitudinal branch overlapping two adjacent longitudinal branches to form a series of mutually-supporting large diamond-form figures and centrally Within the same a series of small diamond-form figures, and transverse coil-springs connecting said branches at the lateral bends of said small central diamondforrn figures, substantially as specified.
