SPRING WEB SEAT CONSTRUCTION Filed Nov. l2, 1937 2 Sheets-Sheet 2 //7 ver/for e6/d, A. fil/m00 Patented May 31, 1938 UNITED STATESY PATE Nr* OFFICE 2 Claims.
My invention relates to spring web seat construction and is particularly adapted for use with chairs, davenports and the like.
Among the objects of my invention is to create a triple action seat construction having a greater number of coil springs of substantially low height interwoven with coiled wire in combination with webbing supported by helical coils-thereby providing a construction aording maximum comfort; to supply a seat construction eliminating the use oftwine or rope; to provide a seat construction simple and economical of manufacture and assembly, and sturdy and lasting in operation, use and wear; to create a construction in which a straight front line is acquired and maintained, and in which side sway and sag is eliminated; to provide a seat construction having vertical, lateral and longitudinal resiliency, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.
While I have shown in the accompanying drawings preferred embodiments of my invention, yet I wish it understood that the same are susceptible of modification and change without departing from the spirit of my invention.
Referring to the drawings, Fig. 1 is a plan view of a preferred embodiment of my invention as applied to a davenport frame with a part in section showing the details of my construe tion; Fig. 2 is a longitudinal cross section on line 2 2 of Fig. l; Fig. 3 is a transverse cross section on line 3 3 of Fig. 1, on a somewhat larger scale; Fig. 4 is a detailed cross section on line 4 4 of Fig. 1 and Fig. 5 is an enlarged plan section of the right hand front co-rner as shown in Fig. 1.
Referring to the embodiment selected to illustrate my invention, a. frame I of wood, metal or any other suitable material has a front rail II, a back rail I2 and oppositely disposed side rails I3.
A pair of spaced metal hangers I4 are attached to the side rails I3 preferably on either side of the centers thereof. A helical expansion spring |5 is attached on one end to each of said hangers I4 and on its other end to a reach rod I6. The spaced reach rods I6 extend laterally and inwardly and each of their inner ends is attached to another helical spring I5. In Fig. 1 where three units of my construction are used to form a davenport, the inner reach rods I6 extend between the inner helical springs I5 as shown.
A webbing II of suitable jute material or the like has its inner end bent back and sewed on itself or is otherwise suitably attached to each of the reach rods I6 and extends longitudinally to its other end where it is attached to the iront rail or back rail I2 by tacks or other suitable fastening means. My invention contemplates either a single webbing between each reach rod I6 and each front or back rail, or a plurality of spaced webbings between each reach rod and each rail. A plurality of spaced longitudinally extending helical expansion springs I8 are attached on opposite ends to each of the spaced reach rods I6 to provide resiliency to the webbing construction or base I9 in a longitudinal as well as lateral plane. y
A spring unit is positioned over the webbing base I9, and its front end lies on the front rail II.
'Ihe spring unit 20 comprises a plurality of compression tension coil springs 2| arranged so that they are substantially contiguous laterally, and spaced longitudinally. My coils 2| are substantially low in height and being preferably three and one-half to four inches in normal height are approximately one-half the height of the coils heretofore used in spring seat constructions. Because of the low height of my coils the need or use of twine or rope to tie the coils is eliminated. My coils also do away with sliding and side sway.
Surrounding the coils 2| at the top portions thereof is a frame 22, preferably of spring steel or other suitable material. A coil wire 23 at each of the outer edges of the frame 22 interweaves to connect the frame and the coils 2| adjacent the frame. A plurality of coil wires 24 extend longitudinally and each interweaves to connect adjacent coils 2|.
There is no frame at the bottom portion of my spring unit 20, but a coil wire 25 on each outer side interweaves to connect outer coils 2|, and longitudinally extending coil Wires 24 interweave to connect the bottom portions of adjacent coils 2|. 1
When spring unit 20 is positioned over the webbing base I9, the front end of the spring unit lies on the front rail l I of the frame l0, and tacks 26 passing through loops of adjacent coil Wire 2,5 and then through webbing II provide rmness in front, a straight front line and eliminate back and front sway.
It is also within the contemplation of my invention that clips may be used instead of coil wire to attach the outer coils to the frame.
My spring unit 20 may be of a desired size their outer ends to each of the oppositely dis-V posed side rails, a pair of spaced reach rods, each of said reach rods having opposite ends attached to one of sai-d laterally extending helical springs, a plurality of webbings, each of said Webbings having an inner end attached to one of said reach rods, and an outer end attached to a front or back rail, and a plurality of spaced longitudinally extending helical expansion springs having opposite ends .attached to said spaced reach rods.
2. A spring seat construction comprising a frame, a plurality of spaced reach rods attached to the frame by laterally extending helical expansion springs, said spaced reach rods attached to each other by longitudinally extending helical expansion springs, webbing extending between and attached to said frame and said reach rods, in combination With a spring unit attached to said frame and supported on said webbing, said spring unit having a substantial number of interconnected compression coils of substantially 10W height, said seat construction having lasting Vertical, lateral and longitudinal resiliency.
