BEDSPRING Filed Sept. 24, 1929 x I r A Jul-26h Patented Sept. 27, 1932 UNITED STATES PATENT OFFICE JOHN F. GAIL, F EVANSTON, ILLINOIS, ASSIGNOR TO SIMMONS COMPANY, NEW YORK, N. Y., A CORPORATION OF DELAWARE IBEDSPR-ING Applieation filed September 24, 1929. Serial No. 394,891.
My invention relates broadly to articles of household furniture and has to do more particularly with bed springs, although it is applicable to such articles of furniture as '5} mattresses, sofas, settees, davenports, day
beds, chairs and automobile seats. I
A particular object of my invention is to provide a device of the type referred to in which the coil springs forming a part of the device are secured together in such a way as to hinge freely with respect to each other, and will be so secured that substantially the entire surface of the device will be yieldable and, hence, will flex freely when a weight is 5 placed upon the surface.
Another object is to provide such a device wherein the individual coils will have a firm surface, while, at the same time, knotting of the ends of the coils is obviated.
Still another object is to provide such a device which will be simple in construction, economical tofabricate, durable and efficient.
Various other objects and advantages will become readily apparent to those skilled in the art as the description proceeds.
Referring now to the drawing forming a.
part of this specification-and illustrating a preferred embodiment of the invention:
Figure 1 is a top plan view of a section of a bed spring embodying myinvention;
Figure 2 is a sectional view taken on the line 22 of Figure 1; 1
Figure 3 is a sectional view taken on the line 3-3 of Figure 2, and Figure 4 is a sectional line 44 of Figure 2.
The device embodying my invention comprises a plurality of coil springs indicated generally at 10. These springs are of any suitable size and number, and are preferably arranged in parallel rows, as shown best ,in Figure 1, the coils of adjacent rows being disposed opposite each other. The marginal springs (not shown) are secured in any suitable manner to a substantially rigid frame (not shown). The coils 10 preferably taper from the center turns 11 thereof toward the top and bottom turns thereof, as at 13 and 14, respectively, so as to represent approxiview taken on the mately what might be termed an hour glass contour.
The coils 10 are secured together at their tops and bottoms in substantially the same manner, as follows: The last complete turn of each of the coils 10 has a crimped portion 12 spaced a short distance from the end of the coil, the terminal portion of the coil being bent as at 13 out of the plane of the last turn of the coil. Substantially opposite the crimp 12 and in the same turn of the coil is a pair of spaced crimps 15 and 15',the portion 16 of the wire between the crimps 15 and 15' being substantially straight. In the same turn of the coil is another single crimp 18, which is preferably smaller than and is arranged adjacent to the single crimped portion 12, so as to be disposable within the loop formed by the crimp 12. (See Figures 1 and 3.)
The coils 10 are preferably arranged so that the single crimps 12 and 18 of one coil are disposed between the spaced crimps 15 and 15' of an adjacent or opposite coil 10, and, as best seen in Figure 1, the coils are preferably arranged in staggered relation; that is, adjacent coils of a given row being reversed with reference to the disposition of, the crimped portions, alternate coils being similarly positioned.
A plurality of substantially helical wires 20 extend transversely of the spring and are threaded through the crimps 12 and 18 of certain coils and the spaced crimps 15 and. 15 of the opposite coils, so as hingedly to connect the coils.
It will thus be seen that in devices embodying my invention, an extremely flexible structure is obtained inasmuch as the. coils are perfectly free to pivot about the hinge provided by the crimps and the helical threaded through them. As best seen in Figure 3, the arrangement of the helical 20 within the space formed between the crimps 15 and 15' enables the coils to pivot with a minimum of friction. Furthermore, the arrangement of the crimped portions 12 and 18 between the spaced crimps 15 and 15 greatly facilitates the threading of the helical through the coils. I
' tions may be made in my invention without deviating from the spirit thereof. Hence, I do not Wish to be limited to the precise construction shown or uses mentioned, except as pointed out in the appended claims.
I claim as my invention: I
1. In a device of the class described, a pair of coil springs arranged in juxtaposition to each other and with parallel axes, an end turn of one of said coils having-a single crimp on one side thereof and the adjacent turn thereof having a crimp adjacent said first crimp, the other coil having a pair of spaced crimps in the end turn thereof arranged to receive the crimps of said first coil in the space therebetween, and means hingedly engaging said crimps.
2. In a. device of the class described, a pair of coil springs arranged in juxtaposition to each other and with parallel axes, an end turn of one of said coils having a single crimp on one side thereof and the adjacent turn thereof having a crimp adjacent said first crimp, the other coil having a pair of spaced crimps in the end turn thereof arranged to receive the crimps of said first coil in the space therebetween, and a helical wire threaded through said crimps so as hingedly to secure said coils together.
3. In a device of the class described, a plurality of coil springs arranged oppositeeach other in parallel rows, the top and bottom turns of said coils having a single crimp on one side thereof and a pair of spaced crimps opposite thereto, and a crimp intermediate the ends of said coils and adjacent said first crimp, said coils being arranged so that the single crimps of one coil are disposed between the pair of crimps of an opposite coil, and means hingedlyengaging said crimps of opposite'coils.
4. In a device of the class described, a plurality of coil springs arranged opposite each other in parallel rows, the top and bottom turns of said coils having a single crimp on one side thereof and a pair of spaced crimps opposite thereto, and a crimp intermediate the ends of said coils and adjacent said first crimp, said coils being arranged so that the single crimps of one coil are dis- -posed between the pair of crimps of an opposite coil, and a plurality of helical wires threaded through said crimps so as hingedly to secure said coils together.
5. In a device of the class described, a plurality of coil springs arranged in parallel rows opposite each other, the top and bottom turns of said coils having a singlecrimp on one side thereof and a pair of spaced crimps opposite thereto, and a crimp intermediate the ends of said coil and adjacent said first crimp, said coils being arranged so that the single crimps of one coil are disposed between the pair of crimps of an opposite coil, and a plurality of helical wires threaded through said crimps so as hingedly to secure said coils together, the terminal portions of said coils being bent transversely of the axes of their associated helicals.
6. In a device of the class described, a coil spring having a single ofl'set loop in each of its end turns and single crimps in the turns adjacent said end turns, and also having a pair of spaced ofi'set loops in its end turns disposed substantially diametrical-.,
ly opposite said first-mentioned loop.
7. A device as defined in claim 3, wherein the alternate coil springs of each row are re-.
versed with reference to the positioning of said single and double crimps.
8. A device as defined in claim 4, wherein the alternate coil springs of each row are reversed with reference to the positioning of said single and double crimps.
