2 Claims.

My invention relates to mattresses of the class comprising an inner spring construction enclosed by quilted edge boxing and by side filling material wherein the side covers are fastened to the edge boxing in a manner producing a rolled edge effect.

An object of the invention is to provide a novel cover for side Afilling and a novel method of assembling the boxing and the covers whereby the covers are quickly and easily fastened to the side boxing in a manner which produces the desired rolled edge effect Without leaving exposed stitches or open needle holes in the cover material.

Another object of the invention is the provision of a novel connection between the side covers of the mattress and an edge boxing which has been constructed to provide a vertical columnar effect wherein the connection between the cover and the boxing accentuates such columnar elect.

The invention has among its objects the production of a mattress of the kind described which is comfortable, durable, attractive in appearance, ecient, satisfactory and which can be simply and economically manufactured.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

In the drawing wherein like reference characters indicate like or corresponding parts,

Fig. 1 is a side View of a portion of a mattress constructed according to the principles of my invention;

Fig. 2 is a section along the line 2-2 of Fig. 1;

Fig. 3 is a section along the line 3-3 of Fig. 2;

Fig. 4 is a detail sectional view of 'a portion of a cover sheet; and

Fig.l 5 is a sectional view along the line 5-5 of Fig. 1.

Referring to the drawing, an inner spring construction is illustrated consisting of the desired number of springs 10 arranged in a casing 1l, it being understood, however, that any other suitable spring construction desired may be employed,

for the purpose.

About the edge of the mattress is arranged a boxing 12 which comprises an outer ply 13, an inner ply 14 and filler material 15. The boxing 12 is quilted by means of eyelets 16 or the like, securing the inner and outer plies and the ller together so that the same is of substantial body. The eyelets 16 may be spaced and arranged in any desired manner but I preferably arrange them in spaced apart vertical rows whereby a columnar effect is given to the boxing. Any desired number of eyelets may be positioned in each vertical row but I nd in practice that four in a row is satisfactory for the usual depth of mattress.

The mattress is assembled by positioning the spring construction on a table or the like and enclosing the edges of the spring construction with a continuous strip of the boxing 12. The outer ply 13- and the ller material 15 of the .boxing are preferably of a width substantially equivalent to the depth of the completed mattress. The inner ply 14 is preferably made slightly nar- 70 rower than the outer ply 13 and the filler material l5 for a purpose hereinafter more particularly described. Filling material 23 of the desired thickness is then placed on the -upper casing 11 so as to completely cover the spring structure 10 75 and a cover 17 is then placed over the filling material.

The cover 17 is provided with a pleat 18, projecting inwardly in substantial alignment with the inner ply 14 of the boxing. The pleat 18 is 30 preferably formed by stitching a seam 19 at a predetermined distance from and parallel to the marginal edges of the cover 17. The cover 17. is originally of such dimensions as to provide a border outside of the pleat 18 of sufiicient width 85 to extend to the outer face of the boxing l2.

The cover 17 is first fastened to the boxing 12 by. connecting the inner ply 14 of the boxing with the pleat 18 by spaced apart stitches 24. The stitches 24 are preferably formed in vertical 90 alignment with the rows of eyelets 16 to accentuate the columnar elect given to the boxing 12 by the eyelets. The pleat 18 having been fastened to the inner ply 14 of the boxing 12 at spaced apart intervals, the marginal edges 20 of the 95 cover are next attached to the adjacent edge of the outer ply 13 of the boxing to form a rolled edge. The connection of the marginal edges 20 with the adjacent marginal edges of the outer ply 13 is accomplished by sewing a tape 21 to 100 the cover and boxing by a plurality of seams or stitches 22. The spring structure and the partially completed mattress are then inverted and the other casing 11 is covered with lling material 23. A cover 17 similar to that already 105 described is then placed over the filling material 23 and its pleat 18 is fastened to the inner ply 14 of the boxing and the marginal edges 20 are connected to the outer ply 13 of the boxing by a tape 21 in the same way as already described 110 for the opposite side of the mattress. A plurality of tuftings 26 complete the mattress. By making the illler 15 of the boxing of substantially the full depth of the mattress a rolled edge eiect is obtained without requiring any additional fllling material outside of the pleat 18. If it is desired to enlarge the roll edge this may be accomplished by placing a roll of filling material outside of the pleat 18 after it is fastened to the inner ply 14 of the'boxing.

The provision, in a mattress construction of the kind described having a prebuilt boxing surrounding the edges of a spring construction in combination with a cover provided with an inwardly projecting pleat fastened to the inner ply of the boxing by concealed stitches and the outer edge of the cover connected with the outer ply of the boxing to form a rolled edge, is believed to be a novel and useful contribution to the mattress art. The accentuated columnar and the roll edge effect are thereby obtained by a simple and economical construction without any exposed stitches or needle openings in the fabric.

Having thus described my invention, it is obvious that various immaterial -modications may be made in the same without departing from the spirit of my invention; hence, I do not wish toy be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. In a roll-edge mattress, the combination of a spring-assembly having upright spiral-springs, paddings for the top and bottom of said springassembly, fabrics covering said top and bottom assembly paddings, a padded boxing around the edge of the mattress including an inner fabric, an outer fabric, padding between said inner and outer fabrics, and a plurality of vertically extending spaced vapart means quilting said inner and outer boxing-fabrics through said boxingpadding and terminating inwardly from the longitudinal margins of said inner and outer boxingfabrics practically in register with the top and bottom edges of said spring-assembly, an inwardly extending pleat in the top and bottom coverfabrics positioned inwardly from the margins thereof in alignment with said inner boxing-fabric, means securing the edge portions o1 said inner boxing-fabric to said pleat at points in alignment with said vertically extending means, means securing the margins of said cover-fabrics and the corresponding margins of said outer boxing-fabric together forming roll-edge casings, and paddings in said roll-edge casings whereby the propensity o! said spring-assembly to expand tends to maintain said inner boxing-fabric -taut and thus preserves the puffed eiiect of said outer boxing-fabric.

2. In the method of making a roll-edge mattress, quilting together an inner boxing-fabric, an outer boxing-fabric and intervening padding along spaced apart vertical lines and terminating such quilting inwardly away from and substan-Y tially parallel to the longitudinal edges of said fabrics, forming a pleat in the inner side of fabrics adapted to cover paddings over the top and bottom of a spring assembly, said pleats being positioned. inwardly from the margins of said cover-fabrics and arranged in alignment with the inner boxing-fabric, stitching the free edge portions of said inner boxing-fabric to said pleat at points in alignment with said vertical lines, stitching together the margin of each cover-fabric to the corresponding margin of said outer boxing-fabric thereby forming roll-edge casings, and lling said roll-edge casings as formed with padding.
