V SPRING CONTAINING STRIP Filed Jan. 12, 7

UNITED STATES JAMES L. MACINERNEY, OF GRAND RAPIDS, MICHIGAN.

SPRING-CONTAININ G STRIP.

I Application filed January 12, 1927. Serial No. 160,543.

This invention relates to fabric strips arranged to form a plurality of pockets for the reception of coiled springs, a number of said spring contained strips being adapted to form a cushion of any required size or shape.

One of the objects of the invention is to provide said strips with means for facilitating the neat and efficient connection of one strip with an adjacent strip. Another object attained by the same means is the provision of extra coverage against which the end coils of the springs will rest.

It will be seen, by reference to the drawing and following description, that a cushion composed of these strips will have no rough, unfinished edges, and will present a neat, finished appearance; that the ends of the spring coils will be prevented from working through the fabric cover, and that this result is accomplished without waste of fabric. It will also be understood that the particular construction of the fabric strips is such as to clearly define the interior dimensions of the top, bottom and side of the pockets, so that the springs will more perfectly fit and be retained therein.

In the drawings:

Figure 1 is a perspective view of a portion of a strip embodying my invention.

Figure 2 is a perspective view of a portion of a modified form of strip to which the invention has been applied.

Figure 3 is a perspective view of a. portion of still another form of strip embodying the invention.

Figure 4 is a perspective view showing portions of a number of strips, such as shown in Figs. 2 and 3, arranged together to form a cushion.

Figure .5 is a sectional view of a detail, taken on the line 5-5 of Figure 4.

Referring to the drawings, the strip of fabric, such as burlap, is indicated at A. The fabric is folded longitudinally so as to form a top 1, bottom 2 and one side 3. Intermediate the top 1 and side 3, and integral therewith, is formed a tuck 4, by a line of stitches 5, and intermediate the bottom 2 and side 3, is formed a similar tuck 6, by a line of stitches 7. Spaced apart partition members 8 of fabric, secured to the top and bottom, divide the interior of the strip into a plurality of pockets to receive the springs 9.

In the forms of strips shown in Figures 1 and 2, the partition strips 8 are narrow, whereas in the form shown in Figure 3, the partition strip 8' is as wide as the top and bottom fabric, and may be secured to the side wall 3 as well as to the top and bottom, 1 and 2, respectively.

In the form shown in Figure 1, the edges 10 and not the. top 1 and bottom 2, respectively, are left unfinished, whereas in the forms shown in Figures 2 and 3, the edges 12 and 13 are turned inwardly, thereby forming a recess between the top 1 and edge 12 and between the bottom 2 and edge 13, for the reception of an end coil of the spring 9.

When a narrow partition strip 8 is used, as shown in Figure 2, the inturned edges are stitched as shown at 14 or may be stapled at intervals, as shown at 15, to hold said edges closely to the top 1 and bottom 2 of the fabric. In the form shown in Figure 3, the stitching 16 which holds the partition strip 8 to the top and bottom fabric may also provide the means for holding in place the inturned edges 12 and 13.

By reference to Figure 4, it will be seen that a number of spring filled strips may be arranged to form a cushion wherein the coiled springs are separated from one another by a single layer of fabric, by placing the closed side 3 of one strip adjacent the open side of another strip; arrangin the tucked portion 4 to overlie the edge of the top 1 and the tucked material 6 to underlie and cover the edge of the bottom 2, and then securing the tucked material to the top and bottom, respectively, by means of stitches 17 or staples 18.

It will also be clear, that the arrangement described, which facilitates the efficient assembly of the strips into a cushion structure, also constitutes means for preventing the wearing out of the top and bottom fabric by the springs, and that this is accomplished by the use of a minimum quantity of fabric.

I claim as my invention:

1. A spring containing fabric strip for cushion constructions, comprising a piece of fabric folded and stitched longitudinally to form a top, bottom, one side member and an intermediate tuck, fabric partitions secured to the top and bottom members to divide the strip into pockets, and a coiled spring in each pocket, the tuck of one strip being adapted to overlie and to be secured to one marginal edge of an adjacent strip when a plurality of said strips are associated together to form a cushion.

2. A spring containing fabric strip for cushion constructions, comprising a piece of fabric folded and stitched longitudinally to form a top, bottom and one side member, two longitudinally disposed tucks, one intermediate the top and side member and the other intermediate the bottom and said side the'tucks being adapted to overlie and to be secured to the longitudinal margins of the adjacent strip when a plurality of said strips are assembled to form a cushion.

3'. A spring containing fabric strip for cellular cushion construction, comprising a longitudinal piece of fabric folded between its side margins to form a longitudinally extending top, bottom, and one side member and stitched to form an intermediate tuck, the other side being open, a series of spring elements mounted in said strip and means for securing the ends of the springs to said top and bottom portions adjacent the open side of said strip, the tuck ofone strip being adapted to overlie and be secured to one marginal edge of the adjacent strip when a plurality of said strips are associated together to form a cushion.

In testimony, that I claim the foregoing as my invention I afiix my signature, this 7th day of January, 1927.

- JAMES L. MACINERNEY.
