Abstract There is shown by this disclosure an arm or leg sleeve that is electrically heated and which has an insulated external layer means and an internal non-insulated layer means for absorbing the heat and directing it to the surface of the arm or leg. The inner layer includes electric wiring arranged in sections with an upper section above the elbow or knee of the wearer and a lower section lying therebelow so that in working of the arm or leg, it will not be hindered by the wires and the wires will not be worked loose by the continuing flexing of the arm or leg when the sleeve is fixed thereover. A control box is provided on the sleeve which can govern the heat to either the upper or lower portions of the sleeve or can combine the upper and lower sections into the same circuit for joint heat or full heat along the full length of the limb. The sleeves are formed of layers including an insulated outer layer means and a heat conducting non-insulated inner layer means. The electric wires are embedded in the insulating material and a wool-like layer is provided for heat conducting engagement to the surface of the limb. In order that the sleeve can be used with a wet surface or over a wet cloth upon the skin surface a removable protective plastic cover of tubular shape corresponding to the shape of the sleeve can be provided within the same to cover up the wool-like heat conducting material and to keep the same from becoming wet. Waterproof plastic cover is attached to the upper edge of the sleeve and retained thereby against inward displacement as the sleeve is pulled over the limb with the protective cover.
An electrically heated form-shaped tight fitting arm or leg sleeve, said sleeve being adapted to substantially the full length of the arm or leg and including respectively the shoulder or the hip of the wearer, said sleeve comprising heat insulated outer layer of flexible outer shirt-like material internally lined with heat reflecting flexible metal foil, and electrically heated intermediate layer having heating wires embedded therein and insulated from one another, and an inner felt-like heat dispersing layer adapted to have full flush engagement with the total skin area of the arm or leg to impart dry heat thereto all of the layers being joined one over the other and together and the sleeve tapering from its upper end of larger diameter to its lower end of small diameter and conforming in full tight fitting engagement with the arm or leg, the electric wiring of the intermediate heating layer being arranged in two sections, one section extending upwardly from an elbow or knee joint to the shoulder or hip end of the sleeve and downwardly from the elbow or knee joint to the wrist or ankle, and a reinforcing stiffening strip band secured about the sleeve adjacent one end thereof and serving to hold the wires more rigid in that area thereof, an electric switch control means fixed to the reinforcing strip band and connected to the wire sections above and below the joint areas and having plug receptacle means for receiving a supply of electric current, and tie cords connected to the upper end of the sleeves and adapted to be tied about the neck or waist to hold sleeves at their upper ends in flush tight engagement with shoulder or hip area.

Claim 4
Dependent Claim
83 words
An electrically heated arm or leg sleeve as defined in claim 1 and a waterproof protective liner covering for use within the sleeve when a wet application is made over the skin of the limb and said covering of said sleeve having cooperating releasable fastening means for the securement of the covering to the upper end of the sleeve and said covering being of tapering formation conforming to the interior of the sleeve and extending substantially to the full length of the sleeve.
