C. D. KARR SLEEPING PAD Nov. .19, 19.35.

Filed May 12, 1934 Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE 2 Claims.

The invention relates to pads which may be applied loosely to any support or attach-ed to a support, such as a spring mattress.

The objects ofthe invention are to simplify the construction of such pads; to secure a fullness which will retain its shape and will hold the outer covering substantially taut; and which will prevent the stretching of the pad.

The improved pad is composed of a plurality of units which may be used separately or in assembled relation.

The invention is fully hereinafter described, and is illustrated in the accompanying drawing in which Y Fig. 1 is a view in perspective of the completed pad;

Fig. 2 is a detail section on either of the lines marked 2 2 of Fig. 1;

Fig. 3 is a detail section on. the line 3-3 of Fig. 1;

Fig. 4 is a detail in perspective of one of the units of the pad in course of fabrication; and

Fig. 5 is a view similar to Fig. 2, showing a modification.

The improved pad is made up of a plurality of units, one of which is shown in course of construction in Fig. 4, and consists of .a bat I of fibrous material, such as cotton, this bat being of the full area of the pad. Upon one face of this bat are placed a plurality of narrow bats I I, of similar material, these bats lying close together. To both faces of this assembly are applied sheets of fabric I2, I3, which are united by seams located between adjacent bats I I, the stitching extending through the bat lll.

In the form of the pad shown in Figs. 2 and 3, two of the units above described are assembled together, the faces carrying the bats. I I being disposed outwardly, and al bat I4 of fibrous material being preferably interposed between the two units. A boxing I covers the sides of the pad and is stitched tol the facing covers I2, I2, as shown at I6, I6, these seams being preferably inclcsed in a binding, as Il. In this assembly the outer covers I2 and I5 of the pad will be of stout fabric, while the inner facing I3 of each unit may 5 be of lighter material. r

A pad thus formed is intended for use without being attached to any support. Its cross seaming intermediate of the narrow bats gives it a pleasarranged units each formed of a hat of brous 2O material, a series of narrow juxtaposed bats of similar material applied to and extending across one face of the first-named bat, fabric facings for the outer and inner surfaces of each of said units, including ticking overlying the narrow bats, lines of stitching connecting the facings of each individual unit located between the juxtaposed bats and passing through the first-named bat of each unit without substantially compressing said bat whereby one face of each unit is substantially plane and the other is characterized by shallow parallel channels, an intermediate bat of fibrous material interposed between the plane faces of the units, and boxing for the end Walls of the pad stitched to the margins of the ticking. 2. A sleeping pad as claimed in claim 1 in which the intermediate bat is uncovered except by the facings of the units, the fibrous material of said bat directly engaging said facings.
