inoasoa Specification of Letters Patent.

Patented Dec., 13", 1921i,

Application filed ,Tune 21, 1920. Serial No. 390,312.

To all whom t may concern.'

Be it known that I, CHARLEs H. Garn, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful lmprovements in Bed-Springs, of which the following is a specification.

My invention concerns features of novelty and advantage in spi'ingcusl1ion constructions, especially, but not necessarily restrictedly, in bed-springs embodying a plurality of upright spiral-springs which support the load.

One leading aim of the invention is the provision of a structure of this kind in which the springs may be locally depressed by a load without substantial effect on the neighboring springs, whereby the occupancy of one side of the bed-spring by one person will have little, if any, influence on the companion occupant of the other side of the spring. 1n other words, the bed-spring is so constructed as to eliminate any tendency for the occupants to roll toward the center of the bed or the lighter weight occupant toward the one of heavier weight.

Further objects of the invention are the production of a bed-spring of this kind which possesses adequate resiliency, which is noiseless, which is relatively simple in structure, which has a suitable transverse crown, and which is comparatively economical to manufacture.

ln order that those skilled in this art may have a full and complete understanding of the invention, both from structural and functional standpoints, a preferred and desirable embodiment of the same has been illustrated in the accompanying drawings which should be considered in connection with the following detailed description of the structure and its mode of operation and throughout the several views of which like reference characters refer to the same parte.

ln these drawings:

Figure 1 is a bottom plan view of the bedspring;

F ig. 2 is a vertical cross-section through the bed-spring on an enlarged scale;

Fig. 3 is a fragmentary longitudinal sec tion on line 3-3 of Fig. 2; and

Fig. 4 is a fragmentary enlarged crosssection at the center of the spring.

Referring to these drawings, it will be seen that the bed-spring comprises a rectangular frame 10 including longitudinal side- bars 11, 11 of lZ-shape in cross-section and endbars 12, 12 of similar form in crosssection, which frame may be constructed in any approved manner. rfhe middle portions of the lower, inwardly-extended flanges 13 of such cross end-bars are connected together by an intermediate, longitudinal, angle-bar 14, having one flange horizontally disposed and resting on and fastened to the flanges 13, 13 and having its companion flange arranged vertically as is clearly indicated in lFigs. 2 and 4. Fastened to the under faces of the inturned flanges 15 of the side- bars 11, 11 and to the bot-tom face of the horizontal flange of bar 14, are two spaced', hollow, transverse-bars 16 and 17 of any desired shape in cross-section, whereby the frame as a whole is provided with six openings between the various intersecting or crossing bars.

The lower flange 15 of each frame sidebar p intermediate bar by the 'clips which engage goles in the upright flange of such latter These cross-wires, which are crimped at intervals as shown in, Fig. 2, are associated at such spaced points with similarly# crimped, parallel, longitudinal wires 22, which are omitted 4at the `cross-bars 16 and 17. Thus, there are three sets of such lengthwise wires throughout the length of the frame. lt will be appreciated, there* fore, that this underlying, yielding supporting structure is divided into six sections, each being supported only crosswise-of the frame, the wires 22 being wholly unconnected with the frame. By reason of this construction, the wires '22 may be depressed without conflict or interference with the intermediate cross-bars, these interlaced wires at rightangles to one another constituting a flexible or pliable foundation or fabric on which the greater portion, but not all, of the upright spiral-springs are mounted.

At each intersection or crossing of the lsupporting wires 18 and 22 an upright spiralspring 23 is mounted thereon in the'. usual manner, such sprin s in elevation having the shape shown in igs. 2 and 3 resembling somewhat an hour-glass form. ln addition, a middle row 24 ot such springs is mounted directly on the top edge of the central bar 14, being held from displacement by the associated clips 21. All around the frame closes'such marginal springs which are se-A cured to it by metal fasteners 29 oi any suitable and convenient form, and the upper or top coils or convolutions of all of the spiral-springs 23, 2d and 26are connected together asshown .by short, helical springs 30 of the construction set forth in my earlier United States Patent No. 1,263,548. e

lhe spiral-springs 23 and 2d oi the cross rows at their waists, or at about one-halt oi their height, are connected together by crimped or deformed, dat, metal-bands 31 which extend unintemiptedly from the outermost spring 23 on one side ot the structure to the corresponding `spring on the other side. Such metal straps are associated with longitudinal wires 32 interloched therewith. at the springs and also locked with such' springs. Thus the upright disposition oi the many springs is assured at all times,

but it is to be noted that none of the elements 31 and 32 are connected to the trame.

lt will' be perceived that by reason oi' the downward and 4opposite sloping or the sectional, underlying, supporting structure .com-posed of the interloclied members 18 and 22 from the center-bar 1d to the frame lside-bars, the top surface of the bed-spring fis givenv the properv transverse crown or arch to overcome sagging in the middle or central zone, and the avoidance of such obv jectionable depression is further fostered or aided by mounting the central or middle row of springs 24 on'the fixed or non-yielding support 14.

In addition, a will be observed that ,bg

i supplying the border of the bed-spring wit the shorter, rupright spiral-springs supported directly on the brackets fastened to the frame, a desirable stiffer margin .for the bed-spring is secured, whereby a person seated on the edge portion thereof does not -unduly depress it.

To those skilled in this art it will be apparent that the invention is not limited and restricted to the precise and exact details of structure illustrated and described, but rather that these mayv be modified within tacones comparatively wide limits without departure from the heart and substance of the invention and Without the sacrice of any of its substantial benefits and advantages. Stated somewhat diderently, the invention is susceptible of a'variety of embodiments of which the one presented is merely a convenient example.v
