Description:

The present invention relates generally to pads. More particularly the invention relates to that type of pad which is used as a protective medium for a mattress or other article and comSprises upper and lower layers of soft fibrous filler material and top and bottom layers of textile fabric with equidistantly spaced rows of stitching for holding the layers and facings in connected relation.

One object of the invention is to provide a pad of this type which is generally an improvement upon and has certain advantages over previously designed pads of the same general character and Sfor the same purpose by reason of the fact that it includes a thin sheet of "Pliofilm" type material between the upper and lower layers of filler material whereby it is materially strengthened and rendered impervious to the flow of air and liquid therethrough.

SAnother object of the invention is to provide a pad of the last mentioned character in which the sheet of "Pliofilm" type material is coextensive with the upper and lower layers of filler material and is held in bonded or connected relation with the latter by way of the rows of stitching.

A further object of the invention is to provide a pad which is generally of new and improved design and is characterized by the fact that it 0 is exceedingly durable and rugged.

Other objects of the invention and the various advantages and characteristics of the present pad will be apparent from a consideration of the following detailed description.

W The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof.

In the drawing which accompanies and forms 40 a part of this specification or disclosure and In which like numerals of reference denote corresponding parts throughout the several views: Figure 1 is a perspective view of a bed having applied to the mattress thereof a pad embodying 45 the invention; Figure 2 is a fragmentary perspective view of the pad illustrating in detail the arrangement of the sheet of "Pliofilm" type material; and Figure 3 is an enlarged fragmentary section50 al view of the pad showing the construction thereof.

The pad which is shown in the drawing constitutes the preferred embodiment of the invention and is adapted primarily for use in connection -8 with a bed B having a mattress M. It is rectangular, as shown in Figure 1, serves as a protector for the mattress M and comprises thin upper and lower layers 4 and 5 of filler material, upper and lower facings 6 and 7, and an extremely thin sheet 8. The layers 4 and 5 are formed of unbleached cotton or like soft fibrous material and are coextensive. They correspond in size to the mattress M and are held in bonded or connected relation with the facings 6 and 7 and the sheet 8 by way of transversely extending, equidistantly spaced rows of zigzag stitching 9 and serve to make the pad soft and give it body. The upper facing 6 is formed of muslin and overlies the top face of the upper layer 4. It is the same in size as the two layers of filler material and has a muslin tape 10 along the margins thereof. The lower facing i is formed of the same material as the upper facing 6 and underlies the bottom face of the lower layer 5. It is the same in size as the layers 4 and 5 and the upper facing 6 and together with said upper facing forms an enclosure for the two layers.

The tape 10 is folded around the margins of the facings and layers and is secured in place by stitching I1. The rows of zigzag stitching 9 extend from one side margin of the pad to the other.

The sheet 8 is preferably formed of "Pliofilm" and is of such thinness that it is highly flexible. "Pliofilm" is a rubber hydrohalide and is characterized by the fact that it is waterproof and comparatively tough and durable. It is further characterized by the fact that it is light in weight and stretchable to a slight extent. By reason of the fact that the sheet 8 is formed of this material the pad is impervious to the flow of air and liquid therethrough and when in place effectively prevents soiling of the mattress by wetting.

The sheet 8 corresponds in size and shape to the layers 4 and 5 and is disposed between the latter. The stitching 9 Is formed of cotton thread and passes through the "Pliofilm" sheet 8 with the result that the latter is securely bonded in place. By reason of the fact that the stitching is formed of cotton thread which tends to expand the perforations resulting from the stitching are effectively blocked or plugged and hence do not effect the waterproof characteristic of the pad. Due to the fact that "Pliofilm" is stretchable to a slight extent there is a certain amount of give to the sheet 8 and the latter hence does not impair the softness of the pad. The sheet 8 not only serves to render the pad impervious to air and liquid but also tends to prevent the pad from stretching or being U pulled out of shape. Because the sheet I renders the pad Impervious to the flow of air therethrough, the pad in a measure serves as an insulator and prevents air from flowing upwards under the occupant or occupants of the bed.

The herein describ pad has a comparatively long life due to the fathat it is rendered rugged by the "Plioflm" sheet betw~en the upper and lower layers 4 and 5 of filler material.. It may be readily washed without damage or injury to the sheet I and may be manufactured at a comparatively low and reasonable cost.

Whereas the pad has been described as being adapted primarily as a mattress protector it is to be understood that it possesses other capabilities of use. It is also to be understood that the invention is not to be restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is: 1. As a new article of manufacture, a mattress pad comprising a thin layer of soft fibrous filler material, coextensive upper and lower facings of textile fabric, having the margins thereof tecured together, and serving completely to encase the layer, an extremely thin coextensive sheet of 'TPloflm" type material fitting directly against and completely covering one side of the layer and serving to render the pad substantially-impervious to the flow of fluid therethrough, and rows of thread stitching extending through the facings, layer and sheet and adapted to connect them together without destroying the SImperviousness of the pad.

2. As a new article of manufacture, a mattress pad comprising thin upper and lower layers of soft fibrous filler material, coextensive upper and lower facings of textile fabric, having the margins thereof taped together, and serving completely to encase the layers, an extremely thin coextensive sheet of "Pliofllm" type material interposed between the two layers and serving to render the pad substantially impervlous to the flow of fluid therethrough, and rows of cotton thread stitching extending through the facings, layers and sheet and adapted to connect the latter together without destroying the imperviousness of the pad.
