3 Claims.

The invention relates generally to mattresses, and more particularly to an improved means for constructing and fastening the cover pads in assembled relation.

One object of the invention is the production of a tufted mattress which due to its novel construction, presents a very neat and uniform appearance, particularly as to the tufting.

Another object of the invention is the production of a mattress having a so-called tufted appearance, in which the component parts are so designed, constructed and assembled that comparatively little hand work is required.

Another object of the invention is the production of a mattress in which the cover pads are of unitary construction and in which the com.- ponent parts of the mattress may be pre-built with a maximum of machine work, thus eliminating numerous steps in the assembling of the mattress, thereby reducing the manufacturing cost, speeding up production and permitting an increased factory output without increasing manufacturing facilities.

A further object of the invention is the novel method of constructing and assembling a mattress having the above features.

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 sectional view of a portion of a mattress embodying the principles of the invention;

Fig. 2 is a perspective view illustrating the manner in which the strips and loops are secured to the cver sheet; and

Fig. 3 is a sectional View through the strip and cover sheet illustrated in Fig. 2.

Referring to the drawing, and more particularly to Fig. 1, the mattress comprises an ordinary unit'ary inner spring construction consisting of the usual plurality of coil springs 2 connected by means of helicals 3. Covering the top and bottom of the spring construction are cover pads 4 each comprising an inner fabric sheet 5 and an outer fabric sheet 6 which are stitched together along three of their adjacent edges to form a bag.

Placed inside these bags adjacent the inner sheet 5 is a layer of sisal 8, and adjacent the outer sheet 6 a layer of padding 9. However, if desired, the bag may be stuffed entirely with padding, omitting the layer of sisal. After the bag has been filled, the open end thereof is stitched together to form a unitary cover pad, after which the sheets 5 and 6, as well as the padding, are secured to one another intermediate their edges by a. plurality of eyelets I0 which are preferably arranged in longitudinal and transverse rows. These eyelets provide apertures through which the tufting means may be inserted and also effectively prevent the padding from becoming hunched. likewise, the eyelets will draw down the pad evenly so that the tufting willy be uniform and even throughout the mattress. This construction provides a unitary pre-built cover pad which will maintain its shape and which is readily and easily handled and transported during the construction of the mattresses without bunching the padding or otherwise distorting the pad. If it is desirable to cover the spring construction with another layer of suitable material such as a sheet 25, the latter also may be secured to the pad by means of the eyelets IIJ.

A cover sheet II is provided, and secured to the inner side of said sheet, as shown in Figs. 2 and 3, are a plurality of strips of material I2 which extend either transversely or longitudinally across the mattress and are positioned adjacent the rows of eyelets I0. Passing between the strip I2 and' the cover intervals corresponding to adjacent eyelets, are the loops I3 which are secured thereto by the stitc ng ILi which secures the strip I2 to the cover sheet Il. These loops, illustrated in Fig. 2,l may -be formed from fabric lace and as shown, may be wrapped twice around the strip l2 to provide a double loop, although if desired only one loop may be formed.

In assembling the mattress the pre-built pads are placed on the top and bottom of the spring construction I, the cover sheets II placed over the pads, and the loops I3 extended through the eyelets IJ. A portion of the top pad is folded back on itself, after which the inner rows of the corresponding loops I3 of both the top and bottom pads are connected by means of suitable ties I5 which pass through the respective loops. The remaining loops are then connected in a like manner, thus drawing the pads 4 and cover sheets Il toward the maintaining the same in place thereon.

A suitable pre-built border boxing is provided,

spring construction and` and, as shown in Fig. 1, comprises an outer sheet I6 and an inner sheet I9 and the padding 20, the sheet I9 having its longitudinal edges I8 folded back upon themselves to enclose the padding 20, the plies being secured together by means of rivets or eyelets 2l. This boxing strip is then positioned along the edge of the mattress with the padded portions 22 tucked in and resting on the spring construction, after which the adjacent edges of the cover sheet Il and the outer boxing ply I6 are stitched together, the adjoining edges being concealed by a suitable tape 23, the stitching being preferably done by machine to present a workmanlike appearance. If desired, the outer edges of the pad 4 or the equivalent sheet 25, if used, may be connected with the inner boxing ply and padding by means of stitching 24', the latter being done by hand, thus preventing any displacement of the pad`4 and the boxing strip.

Thus, it will be seen that the invention provides improvements'in'top and bottom pads and cover sheets of a mattress and improved means for connecting the cover sheets and pads to anchor the rsame' to' vthe spring construction. Likewise, a mattress providing the described improvements, while having the appearance of"a tufted mattress,'is adapted to be readily'rnanufactured with a maximum of machine work and a minimum of hand labor, whereby Vthecost of the mattress is substantially reduced and an increased factory output is obtained without increasing the manufacturing facilities. 4

` Having thus described my'inventiomit is obvious that various immaterial modifications may be made in the same without departing from the spirit'of my invention; hence, I do not wishto 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 secureby Letters Patent isz" '4 1. Ina mattress of the kind described, an in ner spring constructionconsisting of `a`plurality of connected vertical coils, an enclosingv fabric cover including top, bottom, and edge portions, unitary pre-built top and bottoni pads positioned between said cover and spring construction, each" pad consisting of inner and outerfabricsheets and an interposed layer of filling material, each pad having a plurality of apertures therein arranged in rows, a plurality of strips of flexible material respectively extending along said rows of apertures and fastened to said cover, said strips each carrying a plurality of loops respectively projecting through the apertures comprising a row, and a plurality of ties connecting oppositely disposed' loops to maintain said cover in taut close fitting contact with the pads.
