Application filed February 27, 1913 Serial No. 750,997.

To all whom it may concern:

Be it known that I, GEORGE A. MELLON, a citizen of the United States of America, and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Spring Bed- Bottoms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to bed bottoms of the kind in which upright coil springs are utilized, and the invention has several objects, which may be set forth as follows: To produce a spring bed bottom of aconstruction in which the top of the spring bed bottom is divided into two longitudinal sections, in either of which the springs may yield independently of the other section, in: order that when the sectionsare in service to support persons of unequal weight, a greater depression or displacement of the springs of one section will not be transmitted to the springs of the other section. In my improvement, this object is attained by dividing the bed bottom at its surface in i such manner that the springs of each of the sections are free of connection at their upper ends with the springs of the other sect-ion,

and all of them in the two sections are? joined by suitable connecting means to end rails of the bed bottom frame common to both of the sections. Figure I is a top or plan view of myv spring bed bottom, the transverse slats and bottom stay wires being omitted to avoid confusion in the illustration. a side elevation 6f the bed bottom. Fig. III is a perspective view of a portion of the Fig. II is bed bottom frame. Fig. IV is an enlarged top or plan view of fragments of the top coils of two of the upright springs in .a transverse row of said springs, and the hinge connection uniting said coils. Fig. V is an enlarged cross section, taken on line VV, Fig. IV.

In the drawings: 1 designates the end rails of the frame of my bed bottom, which extend the entire width of said bed bottom. These end rails serve as supports for ml rails. The spring supportin upright coil spring supporting 'members, comprising drop hangers 2, longitudinal rails3, securedto sai drop hangeraand transverse slats 4, attached to said longitudiframe members mentioned, inclusive of t e drop:

hangers 2, are supported by the end rails 1, which serve to support the coil spring sections of my bed bottom.

The upright coil springs of my bed bottom are all similar in construction, and they are arranged in rows extending both longitudinally and transversely of the bed bot tom, above and resting on the spring supporting frame suspended'from the end rails 1. Inasmuch, however, as the coil spring structure is divided above its base into sections, I will, for the sake of clearness of description, designate the upright coil springs in one section A and the coil springs in the other section at. These springs are all connected at their lower ends by crossing wires, as is usual in coil sprin bed bottom structures, these wires an the springs beingsupported by the longitudinal bars 3 and slats 4 of the bed bottom frame.

The upright coil springs A and a are connected to each other in both the longitudinal and transverse rows of such springsv by longitudinal tie wires B, which are applied to the top coils of said springs in a manner to be hereinafter explained; and the ends of these tie wires are connected to the end rails 1 of the bed bottom frame by helicaltension springs G, with an object in view that will be hereinafter made clear..

By referring to Fig. I, it will be observed that the upright coil springs A and a, in

no connection with each other, except through the end rails of the bed bottom frame. The outer longitudinal rows of the upright coilsprings A and a areattached to border strips or'bars H, by 'any suitable means, such as wire loops fit coils of the springs, and united at their en to the end rails 1 by. helical tension springs G.

From the foregoing, it will be quite apparent that the spring sections of my bed bottom, comprising the upright coil sprin s A and a, are entirely independent of eac other above the bases ofsaid springs; and,

ted to the to i a;

springs in one section being communicated to the springs in the other section. Therefore, when my bed bottom is in service to support two persons of unequalweight lying above the two sections of the bed bottom, the

springs will yield in each section coinmensurate only to the weight imposed thereon, without the objectionable uneven depression of spring structure that occurs in the ordinary continuous spring structures of bed bottoms when they are required to support persons of unequal weight.

I will next proceed with the description of the hinge sections for the top coils of the upright coil springs of my bed bottom,

which are, as previously stated, included in the longitudinal tie wires, and serve to'join the upright springs, both longitudinally and transversely of the bed bottom. These connections are integral parts of the longitudinal tie wires, and each connection comprises kinks C, formed to extend laterally from spaced portions in the tie wire containing the connection, and in which the top coil of one of an adjoining pair of upright coil springs is fitted. As illustrated in the drawings, these kinks extend beneath the coil they are fitted to, and then upwardly and over the coil. The remainder of the connection is in the form of a loop comprising transverse members D, which extend laterally from the kinks C, return bends E, which receive the top coil of the second upright spring, and a U-shaped portion F, which extends backwardly from the return 4 0 bends E, beneath the top coils of the two springs, toy and preferably beyond the top coil that is fitted in the kink C of the connection. It will be obvious that a connection made as described joins the top coils of springs in a; transverse row of my bed bottom in such manner as to permanently connect them; and, at the same time, permit freedom of vertical movement of each spring relative to the other. It will also be obvious that a series of such connections uniting the springs in the transverse rows and also extending along the longitudinal rows of springs serve to join the springs in the oeaeae l longitudinal rows in a manner that will permit of their movement longitudinally of the bed bottom when they are subjected to pressure. The upright springs may, therefore, be depressed or moved laterally, either transversely or longitudinally of the bed bottom, according to pressure imposed against them, either uniformly or ununiformly; and, inasmuch as the tie wires in which the connections are included are united to the end rails of the bed bottom frame by the tension springs G, the upright coil springs will always be returned to their normal positions when pressure against them is relieved.

I claim: p

1. In a bed bottom, aframe comprising a bottom structure, and a. pair of end rails above said bottom structure, and two-separate spring. sections supported by said bottom structure; said spring sections being secured independently of each other to the same end rails. i

2. In a bedbottom. a frame comprising abottom structure and a pair of end rails above said bottom structure, two sets of spring sections comprising upright coil springs resting on said bottom structure, tie wires 'connecting the upper ends of said upright coil springs, the tie wires in each spring section being independent of the tie wires on the other spring section andbeing connected to the same end rails.

2:). In a bed bottom, a frame comprising a pair of end rails at the top of said frame. and two separate spring sections supported by said frame, the spring sections comprising springs and means at their lowerends connecting the springs of one section with those of the other section, and means connecting the upper ends of the springs in both sections to the "same end rails.

4. In a bed bottom. a frame comprising a pair of end rails and two separate spring scctions supported by said frame. each of said spring sections comprising upright coil springs. tie wires connecting said upright springs, and tension springs joining said tie wires to said end rails.
