KNEE PAD.

To all whom t may concern:

Be it known that l, THOMAS H. SHOOK, a citizen of the United States, residing at Mexia, in the county of Limestone and State of Texas, have invented certain new and useful lmprovements in linee Pads, of which the following is a specification.

This invention relates to new and useful improvements in knee pads.

The object of the invention is to provide a knee pad which is especially adapted for cotton pickers and others, and which will alord maximum comfort to the wearer.

A particular aim ofthe invention is to overcome certain disadvantages which tend to defeat the purpose of various knee pads designed for cotton pickers. Among the results accomplished by the invention is the provision of means for supporting the leg of the wearer immediately below his knee, whereby the pressure which is ordinarily concentrated at the knee, is distributed over a larger surface and the discomfort, when the wearer has been kneeling for a period of time, is alleviated. rlhe said supporting means also maintains the leg of the wearer in a slightly inclined position, whereby less pressure is exerted on the toe.

Another object of the invention is to provide a pad which is dished to form an elliptical support for that part of the wearers knee surrounding his knee cap, and a substantially concentric sump in which the knee cap is received. By such means the weight of the wearer is borne by that portion of his knee which rests o n the elliptical support and the knee cap is relieved. A particular feature resides in a well located in the sump, which has a cushioning eiect and tends to relieve any pressure on the point of the knee cap.

A further object is to provide a knee pad which is simply constructed and which may be manufactured at a comparatively low cost.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following speci iication and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fig. 1 is a side elevation of a knee pad constructed in accordance with my invention, showing the saine fastened on the leg of a wearer in kneeling position,

F ig. 2 is an enlarged plan view of the pad, and

Fig. 8 is a vertical longitudinal sectional view on the line 3*?) of Fig. 2.

ln the drawings the numeral 1() designates a substantially rect-angular U-shaped outer casing or shoe, which is preferably made of heavy, tough, flexible material, such as leather, and slit inwardly from each side, whereby the same may be turned up to provide an end 11, as is shown in Figs. 1 and 2. The slit portions of said end overlap the sides of the shoe and are fastened thereto by rivets 12 or the like, thereby securing the said end in place.

A removable pad is adapted to fit snugly in the said shoe and is composedof a casing 13'which is preferably made of heavy fabric and filled with a suitable stuffing 14. The forward portion of the pad is dished to form an elliptical support 15 and a sub` stantially concentric sump 16. The rear portion of the pad constitutes a transverse supporting bridge 1T for supporting the leg of the wearer immediately below his knee. A well 18 is located at the forward end of the sump and a particular advantage is had thereby. It has been found that said well'which causes a cushioning effect tends to relieve any pressure exerted on the point of the knee cap.

One side of the shoe 10 carries a plurality of straps 19, adapted to extend over the wearers leg and engage in buckles fastened to the other side, thereby securing the pad in place, as is shown in Fig. 1.

lt is pointed out that when the wearer is kneeling his knee cap is received in the sump 16, while his weight is borne by that portion of his knee surrounding his knee cap and which rests on the elliptical support 15. The transverse bridge 1"? supports his leg immediately below the knee, thus distributing the pressure of the wearers weight over a larger surface and keeping the leg in a slightly inclined position whereby a great deal of pressure is relieved at the toe, all of which will be readily seen in Fig. 1.

It is further pointed out that a cushioning eifect is had by the well 18 and the knee cap is relieved from contact with the pad at its point.

Verse Supporting bridge at the rear and aV concave portion extending i'irvvardly therefrom to receive the knee cap with a further depression at the' front of its base forming an air cushion and surrounded by an annular face vdisposedV below the horizontal plane of Said bridge to Support the knee about the cap thereof, and meansA for secur ing the pad upon Vthelego'f a wearer.
