This invention relates to improvements in mattress edge construction, and its pxrincipal object is to provide a. mattress or li e structure with means for producing and maintain- I i ing a trim edge or boxing.

This application is a continuation in part of my copending application, Serial No. 285,298, filed J une 17, 1928.

v Other objects and advantages of my invenm tion', incidental to the above mentioned pruicipal object, will be understood by reference to the following speciication and accompan'ying drawings (2 sheets) in which 1 have illustrated a mattress construction embody- '1,55 ing one form of my invention.

In the drawings:

' Fig. 1 is a side elevation, in which a part of 'the mattress structure is broken away to illustrate the interior construction in section.

Fig. 2 is a plan section.

Fig. 3 is a section taken in a. vertical plane indicated by the line 3-3 of Fig. 2.

Figs. 4, 5, 6, 7 and 8 illustrate the progressive steps in the manufacture. of the side wall 2% structure of the mattress,l and Fig. 9 is a side elevation of the completed side Wall structure before the same is assembled in a mattress. 1

Referring now to the drawings, my im- 3G proved mattress construction includes top and

ottom tick members

10 and 11 respectively which respectivel overlie and underlie snitable quantities o ,padding material as indicated a-t 12 and 13. inside of the respective padding layers 12 and 13, l provide means for resiliently maintaining the to and bottom pads distended or in space relation. This means may be any suitable form of coil spring or other resilient filler, and in' the e0 present instance consists of a plurality of coil springs such as indicated at 11i which are enclosed in individual fabric pockets such as indicated at 15,. The pockets 15 may be formed in any suitable manner. Fabric cover sheets 16 and 17 may be provided over the top and bottom ends of the spring coils to prevent the padding material 12 and 13 from working into the spaces between acent coils. If desired, the inner spring construction may be fabricatedv into a unit structure including the covering sheets 16 and 17. Also, if desired, tufts and tufting cords such as indicated at 18 and 19 respectively may be provided for tying the top and bottom pads together on opposite sides of the spring filler.

For completing the mattress structure and for enclosing the sides or edges thereof, l provide a side Wall or boxing structure indicated generallv at 20. This boxing structure 20 is prefere ly of a padded construction which may be conveniently and economically manufactured in the manner indicated ir. F igs. 4 to 8 inclusive.

rlihe boxing structure herein disclosed includes three strips of suitable padding material such as shown in Figs. 5 and 7. For convenience and economy in manufacture, each of these strips are formed of likepwebs of paddingmaterial which, in the present instance, are in the form of strips of an initial width approximately three times the desired Width of the side Wall.v Such a web or strip is indicated at 21 in Fig. 4. To forin the main side wall pad strip, a strip 21 is folded to form a three-ply member such as shown at 22 in Fig. 5. The multi-ply side wall padding strip 22 is next interposed between outer and inner strips of textile fabric 23 and 2a respectively of suitable Width, the outerstrip 23 being preferably of ticking material and provided with hemmed edges as clearly shown in Fig. 6. The outer and inner fabric strips 23 and 24ers then united, preferably by vertically extended, spaced hnes'offstitching such as indicated at. 25 in Figs. 2 and 9. By stitching the side wall elements together in the manner described, a uted edect is obtained which is not only pleasing in appearance but also of practica-l advantage in that the boxing strip thus formed is quilted, whereby the padding strip is held against shifting between the inner and outer fabric strips.

The side wall structure or boxing strip also includes filler rolls or edge reinforcements which are conveniently formed of the same kind of padding material strips. of which the side wall pad 22 is formed.. The said filler 'roll or reinforcement strips are formed by folding a pad strip 21 to form a three-ply strip like the side wall strip 22 and the three-ply strip is again folded longitudinally to form six-ply strips such as indicated at 28 in Fig. 7. These edge strips 28 are, of course, approximately -one -half the width of the side wall-strip 22 and twice the thickness of the latter. Filler strips or rolls such as 28 are positioned adjacent the opposite edges of the sidewall structure on the inside thereof, substantially as shown in Fig. 8 and are secured intermediate their widths to the side wall strips in any suitable manner. In the presentinstance, the filler strips 28 are secured by means of ties 29 which extend completely through the side wall structure and the filler strip, a reinforcing fabric strip 30 being provided on the inside of the filler strip 28 to provide proper anchorage for the said ties on the inside of the ller rolls. As indicated in Fig. 9, the ties 29 are preferably arranged in spaced rela-` tion to each other and so that they register or intersect with the vertical stitch lines 25. In the present instance, the ties 29 are inserted by means of a special sewinggnachine called a tacker, which inserts a plui'ality of stitches or loops at each tie point.

In assembling the mattress elements, the parts are aranged so that'the inner portion of each of the reinforcing edgel strips 28 (the portion inside ofthe ties 29) extend into position overlying the resilient supporting means as clearly shown in Fig." 1. The side wall thus formed and arranged with respect to the other parts, is secured in place around the' periphery of the mattress byha'ving the hemmed edges of its outer fabric strip 23 vstitched to similar hemmed edges of the top and

bottom ticks

10 and 11, hemmed edges being `brought in a folded or doubled indicated at 26 and' the stitching passin through the edge-embracing tape strip an embraced edge or marginal tick portions as indicated at When the top and

bottom ticks

10 and 11 are united to the side wall structure as above the respective together withexplained, the outer portions of the respec-v tive edge strips are foldedinwardlysubstantially as illustrated in the said'Fig. l.l It will be seen that there is a substantialV reinforcing element at each edge of the mattress which is resiliently supported by the resilient mattress filler. The expansive pressure of the resilient filler tends to rock the edge reinforcing rolls 28 around their connections with the side wall structure .so thatl there is a, tendency to bend or fold the opposite marginal portions of the side wall structure outwardly aroun'd the connections 29 as clearly illustrated at 31 in Figfl. This tend-v ency to thus fold the marginal portions of -the sidewall structure outwardly is most pronounced -in the lines' of stitching 25 with tape strip such as' which the connections 29 are more or less aligned. The outward folding tendency is not so noticeable"`intermediate the lines of stitching 25 and the side wall is nearly straight in the4 high points of the flutes intermediate the adjacent stitch lines 25.

In order to further support the mattress boxing and especially to prevent outward bulgingthereof when the mattress is compressed under load, the 4upper and lower edges of the spring filler or core may be tied to the adjacent portions of the boxing strip. This may be accompanied by means of cord ties 32-32, each extending around an end coil of the springs in the outer row thereof and through the inner fabric or linin strip 24 of the boxing. The ties may a so be passed through the respective cover sheets 16 and 17 so as to assist in maintaining the same in position. The ties or connections 32 preferably take the form of parts of a. continuous cord 33 and may be applied with a curved packing or upholstering needle by hand or in any other suitable manner.

The parts forming ythe abovedescribed mattress structure may be' assembled in any convenient order and manner. One such manner is to form a border strip or boxing into-an endless band by uniting the ends of a proper length of such boxing and then positioning the endless band around the spring filler or core of the mattress. The preformed boxing strip and core may then bc united by means of the connections or ties 32. The to padding and tick may then conveniently fie placed over the top of the core and the adjacent edges of the top tick and boxing united in the manner described. The structure may then be inverted, and the opposite side of the core covered with padding and ticking, thel edges ofthe latter being also united to the adjacent edges of said boxing. If the mattress is to be tufted, the tufting may then be applied.

The top and

bottom ticks

10 and 11 normally have a tendency to pull the -respective upper and lower edges of the side wall structure inwardly, making the boxing bulgy in appearance. SuchA bulging tendency is ef fectivelycou'nteracted and overcome b the above described filler roll edge rein orcement structure assisted by the expansive pressure of the resilient mattress filler.

Changes may be made in the above described-structure withoutdeparting from the spirit vof my invention, the scope of which should be determined by reference to the following claims,lthe same being construed as broadlyA as possible consistent with the having securedto the 'inside thereof, at its ias upper and lower Iedges, felt or like strips formirl internal enlargements extending along e edge of the mattress, said enlargements'being carried by said side casing part "1 5 independently of said top part and a row of springs interposed between and engagingr the enlargements for resiliently supporting the latter.
