I SPRING FILLED MA'rrnEss Application led May 17,

The present invention has for itsobject a simple and novel construction for a mattress having a sprino' center.

A further object of the present invention is to produce a mattress containing springs, which shall be effectively cushioned around the edges without requiring the outer covering or sheathingto be padded for this purpose.

A still further object of the present invention is a simple and novel construction and arrangement to form the sides or edgesof a mattress covering, whereby the desirable stiff ness in the vertical direction and resist-ance to bending or folding about longitudinal lines may be secured in ordinary ticking.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particular-ity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure l is an edge view of a mattress arranged in accordance with my invention; Fig. 2 is a transverse section, on a larger scale, through one side of the mattress Fig. 3 is a perspective view of a fragment of the edge-forming stri for the mattress; Fig. 4 is a view similar to II)*`ig. 3, showing a modifica,- tion; Fig. 5 is a horizontal section, on an enlarged scale, on line 55 of Fig. 2, a portion of the spring cover being shown in section; and Fig. 6 is a section on line 6-6 of Fig. 2, on an enlarged scale.

In carrying out my invention, I form a spring core, thinner than the mattress to be produced, but of approximately the same length and Width. This core may consist of any suitable spring cushion. In the arrangement shown, the spring cushion is made up of vertical coiled springs 1 larger in diameter at the ends than at the middle. The spring cushion is enclosed in a box-like bag 2 of any suitable material. The side and end Walls of the bag are padded on the inside with cotton batting or other cushioning material. For convenience, the cushioning material 3 may be contained within a tube formed by Serial No. 278,614.

the sides and ends 4' and a loose lining 5 for these sides or ends.

It will be seen that when the springs are compressed the endless cushioning pad around the same will serve as a support or bracing means for vthe coils ofthe springs. In other words, if a person sits on the edge of the mattress, the tendency of the springs is to compress more on the outerV sides than on the inner sides. The cushion will largely prevent this, by supporting the springs on the outer sides, so that the mattress will not slope down sharply under a weight placed on the same near the edge, whether the weight be a person sitting .on the edge of the mattress or a person lying on the mattress near the edge. This is particularly advantageous in the case of a person lying on the mattress near the edge of the same, because it prevents such person from rolling off.

The spring core with its cushioned sides is placed between upper and lower layers of any suitable mattressdilling material, as indicated at 6 and 7 the whole being` enclosed in a suitable sheating made of ticking or of a suitable material.

The top and bottom elements of the mattress covering, indicated at 8 and 9, may be simple flat sheets of the desired size and shape. The strip forming the sides and ends, that is the edges of the mattress covering, isV of special construction. A strip of ticking, of the desired width, is folded at intervals along parallel transverse lines, and is stitched a short distance from and parallel with each edge formed by a fold. The result is that the strip is provided with numerous parallel ribs extending transversely across onevside. The l folds are so made that the ribs appear on the backside of the fabric which willib'e the concealed side when the strips are in position in the cover of the mattress. When the cover is completed, the sides and ends, which are made of the strips just described, will have numerous vertical reinforcing ribs that will have a stifening effect and tend to keep the sides and ends of the mattress smooth and unwrinkled in use.

Further stiffness may be secured by reinforcing the ribs. As shown in Figs. 2, 31, 5v

and 6, the strip 10 is lined with canvas l2 or other strong material; the lining being folded and stitched along with the ticking, so that each rib consists of four plies of material sewed together. Ilf desired, the lining may be made of narrow pieces, as indicated at 13 in Fig. 4, being, in fact, tapes that are laid on the ticking and folded along their longitudinal centers with the ticking; the stitching then passing through the tapes and folds in the ticking embraced thereby.' It will thus be seen that the strip forming the side and end walls of the mattress covering may be said to be tucked transversely to produce strengthening ribs.

Thelining is made narrower than the ticking, so that a free marginal portion is left along each long edge of the ticking to 'permit the Strip l0 to be readily sewed to the top and bottom cover members. When pieces of tape are used instead of a continuous lining, the tapes are made shorter than the width of the ticking strip, thus leaving the desired free marginal portions on the strip.

After the mattress has been otherwise completed, a roll edge may Vbe obtained around the top and the bottom by sewing diagonally through the top and bottom corners. In Fig. 6 I have shown the preferred manner of arranging the cords or threads in producing the roll edge.

Starting at the top of the mattress, a short distance from one edge and about midway between two of the ribs in the adjacent side or edge, a cord or heavy thread 14 is passed downwardly and outwardly in such a direction as to go through the side or edge wall beside one of the ribs. The thread is then passed back through the side wall on the other side of the rib and up through the top of the mattress, at such an angle that it will emerge atthe top midway between the lastmentioned rib and the next rib. In this way the cord or heavy thread is caused to zigzag back and forth until an entire corner is given a 'roll-like form;

While I have illustrated and described with partlcularity only a single Vpreferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend tocover all forms and arrangements which come within the definitions of my invention constituting the appended claims.

I claim l. A mattress core comprising a cushion composed of vertical coiled springs enlarged in diameter toward the top, and a pad of about the same height as the springs extending around the sides of the cushion and in intimate contact with the outermost springs from top to bottom.

2. A mattress core comprising a cushion composed of vertical coiled springs whose coils increase in diameter toward the top and kand a covering toward the bottom7 and a pad of about the same height as the springs extending around the sides of the cushion and in intimate contact with the outermost springs from top to bottom.

3. A mattress comprising a cushion composedA of vertical coiled springs enlarged in diameter toward the top, a pad of about the same height as `the -springs extending around the sides of the cushion and in intimate contact with thecoils of the outermost springs from top to bottom, layers of padding overlying and underlying the cushion and said pad,

enclosing the whole.

4. A mattress comprising a cushion composed of vertical coiled springs whose coils increase in diameter toward the top and toward the bottom, a pad of about the same height as the springs extending around the sides of the cushion and in intimate contact with the coils of the outermost springs from top to bottom, layers of padding overlying and underlying the cushion and said pad, and a covering enclosing the whole.

5. A mattress `core comprising a cushion composed of vertical coiled springs enlarged in diameter toward the top, a covering enclosing said cushion and having a tubular section -extending along the edges and from the topand bottom of the cushion, and padding filling said tubular section and holding the inner wall in intimate contact with the border springs. Y

6. A mattress comprising a cushion composed of vertical coiled springs enlarged in diameter toward the top, a covering for said cushion, said covering having a tubular sectionsurrounding the cushion at its edges and of approximately the same height as the cushion, padding filling said tubular section and holding the inner wall thereof in intimate contact with the border springs, layers of padding overlying and underlying the cushion and said v-filled tubular section, and a covering enclosing the whole.

In testimony whereof, I sign this specification.
