rammed Dec. e1, 1929 UNITED STATES PATENT OFFlCE GOMPENSATING PAD FOR MATTRESSES Application filed February 12, 1929. Serial No. 339,394.

This invention relates topads to be used in connection with mattresses.

It is a well known fact that it costs practically as much to have a sagged mattress reconditioned as a new mattress of equal quality would cost, but by use of a compensating pad a sagged and uncomfortable mattress can be rendered practically a new one at a very small cost.

One of the objects of the invention is to provide, in a manner as hereinafter set forth, a compensating pad to bcplaced above or "below a mattress which has lost its resiliency and the stuffing therein compressed by-the weight of the person.

Another object of the invention is to provide, in a manner as hereinafter set forth, a

compensating pad which may be used either' on top of the mattress between the mattress and the covering sheet or under the mattress between the mattress and the springs where the springs have lost their resiliency or become permanently sagged through use.

Further objects of the invention are to provide in a manner as hereinafter set forth, a device for the purpose referred to, which is not only indispensible within the house hold but very valuable in hotels, and especially hospitals where the sick are required to lie for prolonged periods of time, destroying the resiliency of the mattress, and which is simple in its construction and arrangement, thoroughly efficient for its intended use, soft,

liable and comfortable when in position,

5 convenient and light to handle, without interfering with the efficient daily dressing of the bed and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of anovel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shownan embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted'to which fall within the scope of the claims hereunto-appended.

v In the drawings wherein like reference characters. throughout the several view-s:-

as good as j side elevation.

denote corresponding parts Figure 1 shows a side elevation of a bed spring, with a longitudinal sectional view of a mattress superimposed upon a compensating pad illustrating in longitudinal section a l-adaptation therewith of the compensating pad in accordance with this invention.

Figure 2 is a top plan view in upright position of'the compensating pad in accordance with this invention.

Figure 3 is a longitudinal'section of the mattress having superimposed thereon in inverted position a compensating pad shown in Figure 4 is an end elevation of the compensating pad in upright position.

Figure 5 is an end elevation of a modified form of the invention. F Referring to Figure 1 of the drawings, 5 designates a conventional type bed spring having-acompensatin pad in accordance with this invention indicated generally at 6, resting in upright position on the springs and having the original mattress 7 superimposed on the compensating pad 6.

The compensating pad 6 is generallyof rectangular contour of a length greater than its width. Its rectangular dimensions conform to the original mattress with which it is to be used and therefore may ,vary-according to the size of the standard mattress on which it is to be used, such as full size, threequarter size, orv cot size. The body of the compensating pad is flexible and consists of a shell or casing composed of a one-piece up-' per member Sand a one-piece lower member 8 formed of ticking or other strong, pliable fabric which encloses and confines the stuffing or wadding 9. Theuppe'r and lower cas- 9O ing members are secured together at their marginal edges by a row of stitching 8". The waddingor stuiiin g may be formed of any elastic material such as cotton, wool, felt or hair.

The entire upper surface of the compensating pad, when in the upright position shown in Figures 1,2 and 4, is provided with spaced polygonal blocks of tufting formed by a plurality of spaced raised polygonal portions 10. The spaced raised portions are bound at their margins by valleys 11, forming a plurality of polygonal shaped interconnecting valleys over the tog surface of the pads. The valleys are forme as a result of stitching 11 extending transversely through stufiing 9 and from the upper to the

lower members

8, 8. The stitching prevents the stufiing 9 from shifting because it is slightly compressed along the line of stitching and moreover because it is anchored thereby to the upper and

lower members

8, 8. The polygonal tufting formed by the raised portion 10 bound by the valleys 11 form irregular surfaces on the top of the compensating pad making the compensating pad soft and cushion-like and preventing the stuffing from shifting.

The bottom of the compensating pad indicated generally at 12 and when in the upright position is'flat and of rectangular contour. The top of the pad indicated generally at 13, is of rectangular marginal contour. The top face of the pad, in addition to the tufting inclines upwardly from the marginal edges 14, 15, 16 and 1 7 to a central substantially rectangular area 18, and the thickness of the pad increases in proportion to the inclination. The marginal edges 14,15, 16 and l'Z are not of feather or knife edge thickness but are thick enough to provide a substantial body to the pad along its edges. The marginal edges of the pad are however, of a material less thickness than that portion thereof at the'center 18. x

In the modified form of the invention shown in Figure 5 of the drawings, instead of having a fiat bottom 12 as in the preferred form, the said bottom is made complementary with the top. To be more specific, beginning at the marginal edges of the

pad

14, 15 and 17 and the other edge obscured from view in Figure 5, the upper surface is indicated generally at 13 and the lower surface indicated generally at 12 incline inwardly from the marginal edges to a central substantially rectangular area 18 on the top and 18" on the bottom. Both the .top surface 13 and the bottom surface'12 are quilted the same as the preferred form of the invention and the shell or casing is made up of a one-piece top member and a one-piece bottom member ettlivalent to 8 and 8' in the preferred form w ich are secured together at their marginal edges by a row of stitching. The modified form of the invention will compensate for a sagging spring as well as a cupped mattress by reason of its complementary sloping upper and lower surfaces.

In the application of the preferred form of this invention the compensating pad may be used in its upright position, as shown in Figures 1, 2 or 4 or in the inverted position shown in Figure 3. In the latter application the top face 13 is placed against the top of the ing pad will therefore fall under, or be placed over the point where the greatest cupping will occur in the mattress, and by reason thereof will compensate for the sagging or cupping by filling in the cavity formed thereby. Since the compensating pad diminishes in thickness toward the marginal edges, the cavity or cup will be filledwithout effecting the level surface of themattress. The result of the invention, will provide a flat level surface for a person to rest on, without the trouble and expense of buying new bed springs or having the old mattress restufl'ed when the stufiing therein becomes permanently compressed from use. What I claim is 1. A compensating pad for mattresses comprising a flexible body corresponding in length and width to that of the mattress, said body being formed centrally thereof with a substantially rectangular portion of greater thickness than the remaining portion, said body graduall increasing in thickness from each of its-e ges towards said rectangular portion.

2. A compensating pad for mattresses comprising a flexible body corresponding in length and width to that of the mattress, said body being formed centrally thereof with a substantially rectangular portion of greater thickness than the remaining portion, said body gradually increasing in thickness from each of its edges towards said rectangular portion, said body having its bottom flat throughout.
