CUSHION-SPRI NG.

Specification of Letters Patent.

Patented Oct. 15 1918.

Application filed December 31, 1915, Serial No. 69,582. Renewed August 23, 1918. Serial No. 251,179.

provide a cushion'spring construction such,

for example, as used in automobile seats, wherein both the initial expense for material is reduced and the parts may be more rapidly assembled than heretofore.

The invention consists, primarily, in a series of clips arranged at intervals along the usual circumferential base members or border wires and extending upwardly therefrom to embrace the lower edge of the skirting. The invention also consists in clips of this general nature having tangs bent over the lower turn of the usual helical springs,'whereby the springs, circumferential member and skirting may be secured in proper relation to one another; also in clips of the nature first stated having tan'gs for securing the usual cross wires to the border wires. the details of construction shown, described and claimed.

In the drawings, Figure 1 is a fragmentary vertical section of a seat bottom wherein my invention is embodied. Fig. 2 is a perspective view of the lower corner of the spring, parts being broken away, showing more clearly the manner of attaching the web or skirt to the border wire. Figs. 3, 4 and 5 are similar views of one side, showing modified clips. Fig. 6 illustrates the clip shown in Fig. 2 before it is closed upon the border wire and skirt; and Fig. 7 is a similar viewof a modified form of clip. Fig. 8 is a fragmentary perspective view showing a different border member. Fig. .9"

is a perspective view of a clip whereby the skirt, the border wire and one of the helical springs are secured together. Fig. 10 is a similar view of a clip for securing the border wire, cross wires and skirting to gether. Figs. 11 and 12 are plan views, respectively, of the blanks from which the clips shown in Figs. 9 and 10 are formed. Fig. 13 is a fragmentary perspective view of a modified construction.

Similar reference characters refer to like parts throughout the several views.

The invention further consists in' Referring particularly to Figs. 1, 2 and 6, 1 indicates the usual circumferential memher or border Wire, between which cross wires 2 extend .at intervals from side to side. These cross wires support helical springs 3 upon which the upholstering 4 rests in a well known manner; and depending from the marginal edges of the upholstering is a flexible circumferential skirting 5, preferably of leather or fabric, the lower edge of which is turned back upon itself at 6 jaw 11, the latter of which terminates in an inturned edge or rib 12 that is normally spaced somewhat from the side 10) are dropped over the circumferential member or border wire. The skirtin is then raised into the space between the si es or jaws 10--11 of the clip, and by means of a proper tool the side 11 is bent in toward the side 10 until the rib 12 snugly engages under the bead of the skirting. I It will be noticed that the long side or jaw-10 is on the outside of the skirting and lies substantially parallel thereto. It also preferably extends somewhat beyond the rib 12, whereby the wear on the fabric or skirting is lessened. The clips, when formed of thin sheet metal, are exceedingly inexpensive.

In some instances the rib 12 may be replaced by teeth 13 '(see Fig. 7); and, as shown in Fig. 3, the bending tool may be so formed as to crimp the clips slightly at the points 14-15 between the border wire and the bead. Instead of the sheet metal clips heretofore described, wire clips (Fig.- 4) may be used. These clips are preferably formed from a single piece of wire having a longitudinal portion 16 and end portions 18 at substantially right angles thereto, both of which lie in a plane parallel to the skirting 5 and correspond to the side or jaw 10. The portions 18 are extended over the border wire and bent back upon themselves under the bead as indicated at 19. By slightly changing the shape of the, clip, it may be By slightly extending the outer ends of the jaws or clip'elements which correspond to those marked 24 (Fig. 5), flaring elements 28 are formed, between which and the jaws 23 the lowerturn 29 of the helical springs,

together with the'border' wire 1, may be gripped (Fig. 9). The last mentioned clip is readily formed from a blank slitted as shown in Fig. 11, the dashed lines therein indicating the lines about which the parts are to be bent. As is obvious, the border wire and spring may be located below theupper portion of thejaws 10-11, and in this event the elements 2328 would be bent in the opposite direction from that shown in Fig. 9.

In the modification which appears in Fig. 10, the elements 28 are replaced by elements 30 which extend at substantially right angles to the border wire 1 and have their outer margins 31 bent up around the cross wire 32 (each end of which is preferably of U- shape and includes a portion 33 in the same plane and parallel with the adjacent portion of the border wire). The clip is readily formed from a blank slitted as shown in Fig. 12 by bending about the dashed lines.

Referring now to Fig. 13, the circumferential member comprises a base flange 35 a and a circumferential flange 36. The former has resting thereon the lower turn of the helical springs 3, these springs preferably being secured in position by tangs 38 formed by slitting and bending the edge of the flange; and the skirting 5 passes down inside of the flange 36 and is retained in position by tangs 39 struck from the flange 35. These tangs embrace the bead of the skirting and force it against the inner face of the fiangea construction which obviates direct "wear upon the skirting to a large degree.

It is clear that the details of the various parts may be changed widely without departing from the spirit of my invention, and I do not, therefore. wish to be limited otherwise than as indicated by the subjoined claims.
