REED, 0F JACKSON, MICHIGAN, ASSIGNOR TO REYNOLDS SPRING COMPANY, OF JACKSON, IKEICHIGAN, A CORPORATION OF MICHIGAN cusnron SPRING STRUCTURE Application filed September 28, 1931. Serial 565,572.
My invention relates to cushion spring structures to be used in conjunction with automobile seats and backs.
An object of the present invention is to provide a spring structure which embodies rows of coiled springs each of which includes a lower compressed spring formed from relatively heavy gauge wire and an upper spring formed of light gauge wire together with an envelope or casing for each row of springs that serves to eliminate noise and at the same time hold the springs under the desired compression.
A further object of the invention is to provide a cushion spring structure wherein the casing or envelope is formed from flexible material and so assembled with the springs as to maintain them under the desired compression.
The invention further provides a cushion spring structure embodying a plurality of spring units each of which includes a flexible casing in which the cushion springs are housed, the units being such as to permit any number of them to be assembled together to produce a cushion of desired size.
With the preceding and other objects and advantages in mind the invention consists in the novel construction, arrangement of parts and operations to be hereinafter specifically referred to, claimed and illustrated in the accompanying drawings, wherein Figure 1 is a top plan view having parts broken away of a cushion spring structure constructed in accordance with my invention;
Fig. 2 is a side elevation of the same;
Fig. 3 is a fragmentary bottom plan view;
Fig. 4 is a fragmentary vertical sectional view; and
Fig. 5 is a modification of the invention.
Referring to the invention in detail, a pair of rectangular frame members 5 and 6 arranged one above the other in parallel relation is provided. The frame members 5 and 6 are connected together by diagonally extending bracerods 7 which are connected to the rear side of the uppermost frame member and to the front side of the lowermost frame member by the usual clips 8.
The invention provides a plurality of spring units of identical construction. Each of these units consists of a flexible envelope or casing 10 formed from a single length of burlap or other suitable material. The casing or envelope 10 is formed with circular pockets or cells 11 which are produced by vertical rows of stitching 12 at spaced intervals. Arranged in the lower end of each of the cells or compartments is a coil spring 18 formed of relatively heavy gauge wire while a second coil spring14 formed of light gauge wire is superimposed upon the spring 13 at the upper end of each cell or compartment. The upper springs 14 serve to provide a soft and pliant top surface while the bottom springs provide a relatively stiff and less resilient bottom which will absorb most of the vibration and not transmit the same to the upper springs.
In order to maintain the springs 13 and 14 under the necessary compression, so that th'ey will be independent in action, each cell or compartment is drawn orgathered inwardly to provide an intermediate wall 15 of double thickness between the adjacent ends of the springs 13 and 14 and secured by a longitudinally extending stitch 16 which extends from one end ofthe casing or envelope to the other. The free edges of'the casing or envelope are brought together at the center of the upper springs and stitched together as at 17. It will be manifest that the springs 13 will be maintained under compression by the bottomwalls and intermediate wall 15 of the cells while the upper springs will be kept under compression by the intermediate wall 15 and the upper walls of the cells.
In practice any desired number of' the spring units are arranged within the confines of the frame members 5 and 6 and the outermost springs are secured'to these frame members by the usual securing rings 18.
In order to hold the parts together the springs 13 and 14 are secured together by suitable rings 19.
To further lend rigidity to the structure transverse brace rods 20 are secured to the front and rear of the lower frame member side of the brace rods 20 are secured together by rings 21 which embrace these rods as shown in Figure 3.
In the modification disclosed in Figure 5' single springs 22 of relatively heavy gauge Wire are arranged in the outermost pockets 11 to render the structure ma t rigid around its edges.
What is claimed is 1- In a cushion pr Stru ture a firms, a flexible casing supported thereby and having rows of pockets therein, each having a flexible intermediate partition, relatively heavy gauge springs confined in the pockets between the partitions and" bottom vvalls thereof, a light gauge spring in each pocket an anged b tw e t e ri i ti d inper wall thereof, the partition and upper and lower Walls of the compartments serving to maintain the springsunder compression 21 As 'an'article of manufacture, a' spring unit consisting of a flexible liou singdormed tvith "a plurality of longitudinally aimed pockets, expansible springs of difi'ernt gauge Wire arranged in each pocket, a flexible intermediate Wall extending transversely of each pocket and disposedbetvveen" "the p g v V to J As an article of manufacture, a spring unit consisting'of a flexible'cas'i'ngfhaving a plurality of spring compartments therein, eigpai sib'le springs of different gauge Wire arranged ineach comp'artrrien't, and means for'securing opposite Walls of theeasing to gtherat a point betvveenthe the springs.
