' 1925. Serial No; 27,019.

To all wlwm it may concern:

Be it known that I, LOUIS A. Sonnorr, a citizen of the United States, .residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Methods of Making Spring Assemblies for-Upholstery; and do hereby declare the following to be a full, clear, and exact descri tion of the invention,

such as will enable 0t lers skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in methods of constructing spring assemblies for upholstery purposes, including seat cushions and backs and sides for furniture, automotive vehicles, railway cars and the like and has for its particular object to provide a method whereby, during fabrication of one part of the structure an interengagement thereof with the other is effected which is permanent and of such a nature as to provide great strength and durability in the completed articleand whereby a very considable saving in labor and materials is efiected.

The several steps of the method are fully illustrated in the accompanying drawings wherein 7 o I Figure 1 is an lnverted perspective vlew of a fabric structure constituting a part of the finished product resulting from carrying outthe method of the invention;

Fig. 2 is a view similar to Fig. 1 showing parts of .the metallic base associated with portions of the fabric structure;

Fig. 3 is a perspective view of the completed structure with the exception that only a few of the cells or pockets thereof are shown to contain springs.

The present application is a divlsion of my application, Serial No. 21,816, filed April 9, 1925, for improvements in spring assemblies for upholstery, which, as originally filed, described and claims said product and the method of making the same.

In carrying out the method aforesaid, there is first constructed a fabric housing comprising a top wall or cover '1, a pair of side walls 2 and a pair of end walls 3, all of the latter being joined along their upper edges with the top wall 1 in any suitable manner. One end wall 3 is secured along its side edges to the contiguous ends of the side walls 2.

Prior to securing said end .wall 3 to the side walls 2, the longitudinal partition walls 4 are secured to the top wall by lines of stitching 5, the said partition walls being provided along their free edges with hems 6 before being secured to the top wall 1.

Narrow transverse partition walls 7, similarly provided with hems 8, are secured by -lines of stitching to the'top wall 1, the relative arrangement of the side and end walls 2 and 3 and the partition-walls 4 and 7 being such that when said several walls are disposed perpendicularly to the top wall they will border substantially square pockets or 1 cells of uniform size.

A rectangular 'or substantially rectangular border wire frame 9 (Fig. 3) is then secured preferably by stitching to the free edges of one end an .two side walls of the structure. Intermediate wires 10 are then passed through the hems 6 of the partition walls 4., said wires being of such length that they project over diametrically opposed portions ofthe border wire frame 10 about which they are looped as shown in Fig. 3.

Wires 11 which, preferably, are crimped at regularly spaced intervals, equal substantially to the diameter of the cells or pockets formed by the peripheral and partition walls, are passed through the hems 8 of the partition walls 7 and, at their ends, are looped about the border wire frame, the crimps or bends 12 of the wires 11 being disposed at the points of intersection or crossing of said wires 11 with the wires 10.

The structure now presents a flexible fabric superstructure interlaced with a skele ton wire base, the wires of the latter maintaining the free ends of the peripheral and partition Walls in the same or substantially the same relative positions as the other ends thereof which are attached to the top or cover fabric 1, thereby providing pockets or cells to receive coiled springs 13. But the wires 10 and 11 are not of suflicient crosssectional dimensions to properly support the springs 13 so that the additional light supporting wires 14: must be provided. These are inserted transversely through the heme 6 and 8 respectively in staggered relation to the wires 10 and 11 and just above 0;

inwardly of the latter so as to bridge the mouths of the pockets or cells. I

' After the wires14 have been inserted and before the still detached end wall 3 of the structure is joined along its still free three edges to the side Walls 2 and the border wire frame 9, the springs 13 are introduced in collapsed condition into the several cells or pockets through the narrow slits or slots means of the tool shown and described inme Letters Patent No. 1,352,157 grantedto on the 7th day of September, 1920.

the best' manner of carrying out the inven .tion to produce the best and most economical structure exemplified in the drawings but the invention is not limited to the production'of the precise structure illustrated nor.-

to the exact sequence or nature of said steps as the latter may be changed and varied to a considerable extent to produce the structure illustrated or modifications thereof without departing from the invention asdefined in and-by the appended claims.

I claim as my" invention:

1. The method of making spring assemblies which consists in constructing a fabric structure presenting a series of pockets or cells adapted to contain coiled springs, and fabricating a foraminous wire base for one end of said structure by successively interlacing certain of the several component elements of the base with walls of the pockets of said fabric structure and then securing all of the component elements of said base against displacement relatively to each other, and inserting springs.

building a fabric superstructure presenting a series of cells or pockets adapted to receive. and confine springs, fabricating a foraminous Wire base forthe bottom of said superstructure by successively permanently co nnecting several of the component. parts vof said base with walls of said cells or pockets, and thereafter permanently congnecting all of the component parts of said base witheach other, and inserting springs into said pockets orcells.

3. The method of making spring assemblies which consists Pin the several steps of "constructing a fabric superstructure presenting pockets for containing springs, constructing a substantially rigid skeleton base including relatively intersecting spacing p -.-;bars by successively connecting the latter The foregoing description is directed to said base in spaced relation to each other to thereby permanently maintain the walls of said pockets in spaced relation to each pockets.

4.-The method of making spring assemblies which consists in the several steps of constructing a fabric superstructure presenting pockets for containing springs, constructing a substantially rigid skeleton base including relatively intersecting spacing bars by successively connecting the latter with the walls of said cells or pockets and securing all of the component .elements of said base in spaced relation to each other to thereby permanently maintain the walls of said pockets in spaced relation to each other, connecting spring supporting elements with said spacing bars and the walls of said pockets. and inserting springs into said pockets.
