• the objects of my invention are, first to provide a rheostat in a glass cylinder, so that i it may be protected from accidental touch and yet be" visibleand easily accessible; secondly to provide a rheostat of such construction that the ordinary electric lighting current maybe adapted to medical use.
• a further objectof the invention is to provide a novel and improved resistance element.
• 1 is the incoming w'ire from the source of electrical energy
• 2 isthe outgoing wire.
• These wires are connected by the ordinary plug with any lamp socket. These wires pass along through grooves in the under side of 9 in the post 5 and has on its opposite and the insulating base 3 to the electric light bulbs 4, 4, thence one wire passes to the post 5, the other to the post'6.
• A'ro'd having an insulated handle 8 passes through the slot inner end a sponge 10 forming one electrode.
• the other, electrode 11 is-firmly attached to the insulated end 12 of a rod 12, which' latter passes through a holein the post 144 and is provided with an insulated handle 13.

• the current By moistening the sponge electrode 10 the current may be increased, the amount of current transmitted depending on the dampness of the sponge.
• the'operator grasps the handle 13 and pushes the rod attached thereto inward toward the-sponge 10 until the current passes from one electrode to the other and through the patient in contact at 18 and 19.
• the amount of current transmitted depends upon the approximation of the electrodes to each other and upon the compression of the damp sponge by the pressure of the electrode 11 upon it.
• the lamps may be dispensed with in case batteries or other source of electric current are used, and the current passed direct to the regulator.
