SPRING-CUSHION on THE LIKE.

Application filed February 1, 1915.

To all whom it may concern:

Be it known that we, ELMER JAooBs and WILBERT WARRING VAN SLYKE, citizens of the United States, and residents, respectively, of Albion and of the city of Detroit, bothin the State of Michigan, Umted States of America, have invented certain new and useful Improvements in Spring- Cushions or the like, of which the followlng is the specification.

Our invention relates to improvements' n cushions and more particularly to the means for fastening the facing at the bottom side of the cushlonand also to the means for fastening the bottom covering material, 1n

the case of a closed bottom cushion, and the object of the present invention is to prov de a fastening device for this purpose in whlch no sewing is necessary and in which the op eration of. fastening may be rapidly per formed.

A further object is to provide a fastening device which will enable a uniform tension tobe maintained at all points in the facing material.

A. further object is to provide a fastening device by which the bottom covering material is subjected to no tension and in which it is impossible for the facing material or bottom covering material to become displaced over the edges of the cushion and a still further object is to provide protecting means for the facing material and bottom covering material at the bottom edges of the cushion.

Our invention consists of a cushion frame having pointed prongs suitably spaced and carried at the bottom edges ofthe frame, and a supplemental frame engaged'by the said prongs, all as hereinafter more particularly described and illustrated in the accompanying drawings, in which Figure 1, is a perspective view of one corner of a cushion, bottom side up, with clamps carrying the prongs according toour invention and showing part ofthe facing material cut away. Fig. 2, is a perspective view of a supplemental frame which is adapted to engage the inside faces of the prongs in Fig. 1. Fig. 3, is .a perspective view of a modification of our invention in which a continuous frame is used to carry the prongs in place of the separate clamps shown in Fig. 1. Fig. 4, is a cross section of the method of fastening in the case of Specification of Letters Patent.

Serial No. 5,458.

an open bottom cushion. F 5, is a cross section of the method of fastening in the case of a closed bottom cushion.

Like characters of reference indicate corresponding parts in the different views.

1, are the springs of the cushion.

2, is the point at which the top edge of the facing is fastened.

3, is the facing material.

4, is a continuous angular frame which extends around the bottom outside edges of the spripgs and which is suitably attached to the springs.

5, are pointed prongs extending perpendicularly outward from the said frame.

6, is a supplemental frame adapted to engage the inside faces of the prongs 5.-

7, is the bottom covering material.

8, is a sheet of cardboard or other suitable material which covers the lower side of the springs.

9, is the border wire surrounding the springs of the cushion and to which the same are fastened.

10, is a clamp which is fastened to the border wire and the spring and carries one or more of the prongs 5, thereon.

The method of constructing a cushion employing our invention is as follows :The springs are made in the usual way and the clamps 10, carrying the prongs 5, are built into the springs. The upholstering of the' top is done as usual and the top edge of the facing is attached along the edge 2. The facing is then pulled to the desired tension and pressed down over the pointedprongs 5, so that the same penetrate the facing material. The supplemental frame 6, is then.

' laid in place outside the facing material and inside the prongs which are then bent over this frame as shown in Figs. 4, and 5, which holds the facing firmly in place. 1

,In the modification of our invention in which the continuous angular frame 4:, is employed the procedure is exactly as described above except that in making the springs this frame is built into them instead of the clamps 10.

In the foregoing we have described our invention as applied to an open bottom cushion but it is to be pointed out that it is equally applicable to a closed bottom cush ion. In applying it to a closed bottom cushion the only change in the procedure is that a strip of cardboard or other suitable material is placed over the bottom of the springs and after the facing material is in place and the prongs have penetrated it the bottom covering material is then turned over on itself to form a double thickness as at 11, and

is then pressed down over the prongs 5, which are then displaced over the supple can be obtained as it is only a case of prop- V erly adjusting the facing when penetrating it by the prongs. 1

Our invention is of great advantage in the case of closed bottom cushions both due to a great saving in time of manufacture and also in producing a much superior article. In former types of closed bottom cushions the facing and bottom covering material are sewed together. In this method, the facing and bottom covering material are as one continuous piece and both are under tenslon due to the action of the springs, and of.

course as a result the stitching at the connection is also under tension and incase of one stitch breaking the whole cushion goes. A further disadvantage of this old method of fastening is that the facing and bottom covering material are free to slide over .the edges of the cushion and as a result, particularly in cushions having very deep springs these materials are soon displaced and the cushion loses its proper, form.

Another disadvantage of these types of cushions which is completely overcome by our invention, is that there is no protection provided at the bottom side of the cushion against wear due to the sliding about of the cushion of the seat. 7

All the foregoing faults are overcome by our invention as there is no sewing of the facing or bottom covering material at the bottom connection of the same but the two materials are entirely separate and absolutely no tension is carried by the bottom covering. Furthermore no sliding or displacement of the materials can occur as they are fastened firmly along the bottom edges of the cushion frame. In our method the cushion is much more durable, as there is protecting means provided at. the bottom outside the facing and bottom covering which means rests on the seat and prevents any wear on the cushion due to the same sliding about. If desired a corded welt may be made at the outside edge of the bottom covering by simply inserting the cord between the layers of the same when it is bent back on itself.

Many modifications may be made in our invention without departing from the spirit of the same or the scope of the claim and the forms shown are to betaken as illustrative and not in a limiting sense and our invention is desired to cover any method'of making cushions. in which this principle of fastening is employed and is to be applied to either open. or closed bottom types.

What we claim as our invention is In a springcushion or theflike, the com bination with the bottom edge border wire frame and the facing material extending around and underneath the same, and the springs "and the outer supplemental border tom of the supplemental border frame around which they are clenched.
