2 Claims.

heat obtained therefrom was bandages would not emit a very manufacture. I I Another object of my invention is to provide a therapeutic bandage in which all splices between the lead wires, resistance wires, and thermostat and the like are woven into the'structure.

Another object of my invention is to provide a therapeutic bandage which emits a high degree 01' heat for a given area.

Another object of my invention provides a therapeutic bandage having no splices or open connections adjacent the bandage.

Anotherobject of my invention is to provide a novel process of manufacturing a therapeutic bandage.

Another object 01 my invention is to provide therapeutic bulbs in the place of thermostats in the bandage is attached.

fragmentary view taken on the line Fig. 3 is a plan view of my novel heating bandage showing therapeutic bulbs connected in each resistance wire line.

Referring to the drawing, Fig. 1 shows a heating element comprising interwoven warp and insulated of non-flammable yarn patient and it short circuiting of the leads. The leads 1 are the resistance wires 2 at 8 interiorly of the bandage. The lead wires and resistance wires are all woven into Another object of my invention is to provide forehead, or where a local applica a heatin ba a e with even a distribution tion of heat is desirable. Strain relief members Another o i or my inven ion is to provide 9 and III are attached to the lead wires 1 and a therapeutic bandage with strain relief memthe common lead 3 and woven directly into the bers disposed on the leads woven into the heating heating element. These 4 members prevent the element. leads from pulling out of the element. A selvedge -ing element. Lead wires II is provided around the edges of the heating element.

Referring now to Fig. 3, I show interwoven warp and weft elements 20 and 2| connected to a common wire 22 at 23 internally of the heat- 24 and 25 are connected to the resistance wires 2! at 26. Connected in the resistance wires internally of the heating element are therapeutic lamps 21 and 28 for treatment of a patient. It will be evident that thermostats may be placed in either of these lines in place of the lamps. Strain relief members 29 and 30 are disposed on the lead wires 24 and 25.

The process of manufacturing my novel heating element comprises the affixing of the necessary warp strands to the loom to provide the maximum width of the bandage. Resistance wires are inserted across the warp and are properly afiixed thereto and insulated. Strain relief members are attached to the lead wires connected to the resistance wires, and also to the common lead wire. These are woven into the heating element. The two windings are simultaneously interwoven across the warp. When the last turn of the winding is completed, I pull through the third or common lead to which the thermostats or lamp sockets have been previously attached in series. The selvedge is then pulled across the warp which completes the process of making one complete bandage. It should be noted that all connections in this heating element are made internally of the heating element. The heating element is then vulcanized between two rubber sheets or cemented therebetween. The manufacture of the element. shown in Fig. 2 starts the same as the element in Fig. 1. In this element, the thermostats or elements are connected in series with the resistance wires.

Three heat operation, low, medium, and high may be obtained by any suitable switching means. One means shown in Fig. 1 is for provision of a switch 30 having legs 3| and 32. Low heat operation is obtained when the following circuit is completed: wire 33, leg 32, wire I, resistance wire 2, and common lead wire 3. Medium heat is obtained on completion of the following circuit:

wire 33, leg 32, wire 1, resistance wire 2 and common lead wire 3. upon completion of the following circuit: wire 33, switch legs 3| and 32 connected to resistance wires 2 through lead wires 1- to the common lead wire 3.

It will be evident from the foregoing that I have provided a therapeutic bandage which has even heat distribution, three heat operation, a high degree of heat for a given area, and one which has no external splices or connections.

Various changes may be made in the specific embodiment of my present invention without departing from the spirit thereof or from the scope of the appended claims.

What I claim is:

1. In a comparatively small electric therapeutic bandage, in combination, interwoven warp and weft element comprising resistance wires wound in multiple, lead wires connected to said resistance wires and woven into said element, a wire common to said resistance wires connected thereto and woven into said element, strain relief members on said common wire and said lead wires woven into said element, thermostats in said common wire woven into said element, and sheets secured on opposite sides of said heating element.

2. A method of manufacturing a comparatively small electrically heated therapeutic bandage comprising of the steps of the affixing of the necessary strands to a loom of the maximum width of the bandage; weaving resistance wires having strain relief members attached thereto simultaneously across the warp, pulling through the warp strands; connecting lead wires to said resistance wires and weaving them simultaneously across the warp; weaving a common wire havin a strain relief member attached thereto and thermostats in series therewith into said element, and connecting said common wire to said resistance wire interiorly of said heating element; and disposing waterproof sheets on opposite sides of said heating element.
