Specification of Letters Patent.

Patented June 15, 1920.

Application filed October 27, 1919. Serial No. 333,588.

To all whom it may concern:

Be it known that I, SIMON GAINER, a citizen of the United States, and a resident of Chicago, Cook county, and State of Illinois, have invented certain new and useful Improvements in Sectional Springs, of which the following is declared to be a full, clear, and exact description.

This invention relates to sectional springs and is in the nature of an improvement upon the, box spring shown and described in my prior Patent No. 1,296,068, dated March AL, 1919. The principalobj ec't of thepresent invention is to provide a spring for beds and other furniture, made up of plurality of sections, which may be readily secured together, and detached from each other and having connecting means between the adj acentrows of springs of the several sections free from and movable independent of any other-edge members of the spring. I have found from experience that better results are obtainedby making the connecting members between the adjacent rows of springs of the several sections, independent of the lengthwise extending edge members that usually connect the springs, and in'the pres ent invention I tie together the marginal side rows of the spring sections so that when one marginal row is depressed theadj acent row of the adjacent section will also be depressed, more or less, without, however, effecting the marginal lengthwise extending row of springs to such a great degree. In this way I obtain greater comfort with the use of the spring-without sacrificing any of the beneficial results" obtained in a spring such as is disclosed in" my prior patent. The invention consists in the several novel features hereinafter fully set forth and claimed. v

The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a plan, partly broken'out, of a sectional spring embodyinga simple form of the present invention; Fig. 2 is a side elevation thereof, partly broken out; Fig. 3 is an end View of the spring'looking in the direction of the arrow 3 in Fig. 1 and showing the covering and upholstering omitted; Fig. 4' is a detail, vertical, longitudinal section taken on the line 4-4 of Fig; 1 Fig. 5' is a detail, vertical, cross section taken onthelinje 5'5 of Fig. 41,; Fig. 6 is edema, vernea1, resss e ion taken on tical, cross section taken on the line 77 in Fig. 1; Fig. 8 is a plan of a fragment of a slightly modified form of the invention and Fi 9 is a side elevation of the parts seen in Fig. 8.

Referring to said drawings, which illustrate a simple embodiment of the present invention, the reference characters A, B, C, designate three sections, which comprise a complete bed spring, and as said sections are substantially similar in construction, I shall proceed to describe one of them, which description, it is'understood, applies to all.

A rectangular bottom frame is employed forsupporting the springs, which are of the usual and well known coiled compression spring construction, and said frame is shown as comprising horizontal frame members 10 connected by horizontal frame members 11. The frame members 10 extend lengthwise of the complete spring and the frame members 11 extend crosswise thereof.

Secured to and projecting up from the frame members 10 are short posts or upright members 12, to the upper ends of which are secured bars or upper frame members 13 that extend lengthwise of the complete spring.

Secured to the lower frame members 10, 11 is a bottom 1% upon which are secured coiled compression springs 15 of the usual construction employed in bed springs, the upper ends of said springs being tied together by wire or heavy cord, 16, as is usual in the construction of bed springs.

The springs 15 are usually arranged in rows in each section, as shown, and the marginal side rows 17, 18 (see Fig. 1) are connected at their upper ends to crosswise ex tending bars 19, 20, preferably formed of angle iron bars, which extend between the ends of the upper frame bars 13. The springs may be secured to said bars by any suitable means, and I have illustratedwire clips 21 for this purpose. Each bar 19, 20 may comprise a single bar if desired, but I prefer to make it up of a number of sections as shown at 22, '23 arranged end to end and hingedly connected together by loops or other similar connections 24, which extend through the horizontal webs of the angle iron bars, as is clearly illustrated in Fig. 6. This arrangement permits the far end of one section of any bar to be depressed considerably without correspondingly de pressingthe entire bar, in other words, each bar is capable of being depressed at either end without materially depressing all of the springs connected to the other section of the bar. Endwise movement of the bars 19, is prevented by the end portions of the upper frame bars 13.

Each cross bar 19 is provided with bar connecting devices, here shown as comprising pins 25, which project laterally therefrom and each cross bar 20 is provided with sockets 26 adapted to receive said pins to thereby connect together the adjacent 7 cross bars 19, 20. If desired said sockets may be formed by providing holes in the bar 20 or they may be made of separate fixtures secured in holes in the cross bars 20. For the purpose of guiding the pins to the holes in the sockets when assembling the several spring sections into a complete spring, the upper ends of the socket members 26 are formed'with diverging end portions 27 arranged along the outer faces of the cross bars 20, which act to guide the pins 25 when one section is moved down along the other section to couple the two together. Obviously, many forms of con nections may be provided between cross bars 19, 20 to secure them together so that they will move in unison, but the one illustrated is very simple and serves the purpose. To prevent separation of several sectionsafter they have been placed together with the pins in the sockets, provide hooks or latches 28 on the sections, which hook over pins or eyes 29 on the adjacent sections as is clearly illustrated in ig.2.

The sectional spring shown and described may be used with the ordinary mattress as is customary or if desired the sections may be upholstered to form a sectional box spring, and in the drawings I have illustrated cushions or upholstered material 30 above the springs 15 and'the usual ticking 31 (see Fig. 7 covering the upholstering material and frame work of the springs.

In the modified form illustrated in Figs. 8 and 9, the top bars 13 are made shorter than the lower bars 10 to permit the cross bars 19 20 to extend the full width of the spring, and in this case I have shown hooks or latches 28" secured to one cross bar and arranged to hook over pins or eyes 29 upon the adjacent cross bar. This arrangement prevents separation of the spring sections and positively connects together the two bars 19 20". It is to be understood that r the springs 15 are secured to thecross bars as in the preferred form and that the cross bars may have the pin and socket connecting devices or other fixtures for connecting them together.

l/Vhile the invention has been shown as applied to what is known as hard edge box springs, it may be applied equally as well to spring edge box springs, that is to say,

the upper frame members 13 and supports 12 may be omitted and the outer or end rows of springs 15 of each section may be connected by a wire or rod as is customary in bed springs or box springs. Moreover while the invention has been shown as applied to a bed spring it may be applied equally, as well to the springs of couches, settees, davenports, seats or other analogous articles where sectional springs may be employed.

The advantages of the sectional spring embodying the present invention are many. In place of carrying about an entire spring, each section may be easily handled separately and put in position and connected with the others to make up the complete spring. Moreover when the weight of the body is applied to any cross bar the adjacent portion of the contiguous cross bar and springs connected therewith are moved in unison therewith without, however, disturbing the distant springs or without moving the entire marginal frame asis the case in the sectional spring of my prior patent. It is to be understood that while I have shown three sections as comprising a whole spring two or more may be used to obtain the same results. The frame may be constructed of wood or metal as desired, for use on wood or metal beds or other furniture.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and de- 100 scribed, but intend, in the following claims, to point out all of-theinvention disclosed herein.

I claim as new, and desire to secure by Letters Patent:
