WILLIAM SCHEIDEL, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 766,468, dated August 2, 1904.
Application filed December 31, 1903. Serial No. 187,277. (No model.)
To (ti/Z 1072 0111 it may concern.-
Be it known that I, IVILLIAM SCHEIDEL, a citi- Zen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rectiiying and Interrupting Alternating Currents, of which the following is a specification.
The present invention relates to the appliances and circuits used in operating inductoriums and like apparatus, in the operation of which a high-frequency current is employed, and has for its object to provide a simple and efficient structural arrangement and combination of parts whereby alternating or other like variable electric currents are effectively utilized in the operation of inductoriums and the like and which is adapted to eliminate to a very material extent the usual rapid generation of heat and increase in temperature in the ordinaryform of electrolytic interrupter when working with alternating currents, and in such elimination of heat attain a constant and effective high-frequency interruption of the current supplied to an inductorium or the like during long-continued use of the apparatus, all as will hereinafter more fully appear, and be more particularlypointed out in the claim.
In the accompanying drawings, illustrative of the present invention, Figure l is a diagrammatic view illustrating the general arrangement of the present apparatus. Fig. 2 is a vertical section of an electrolytic interrupter embodying the present improvement.
The present improvement involves the rectification of alternating and like variable electric currents during the passage of the same through a high-frequency electrolytic interrupter, so that the dual operation of interruption and rectification will occur in a substantially simultaneous manner in the single cell of the present apparatus, and with which the passage of one phase of an alternating or like variable current through such cell is prevented, while free passage is afforded to the other and companion phase of such alternating or variable current and a simultaneous high-frequency interruption of such last-mentioned phase efi ected prior to its passage to the primary winding of the inductorium or other like apparatus.
To such end the present invention consists in the formation of the cathode element or electrode of the electrolytic interrupter from aluminium or other equivalent substance which when acting as a cathode ofl ers but little resistance to the passage of the electric current, but which when acting as an anode prevents the passage of such current. The other element or electrode of the apparatus is formed of platinum, carbon, or the like, while the electrolytic fluid will be phosphate of soda, or
scribed, and which constitutes the cathode element or electrode of the present apparatus and to the end is provided with a bindingpost connection 7 for one of the line-wires of the alternating electric circuit of the system.
8 is the anode element or electrode formed of platinum wire or like substance and secured in the lower end of a hold er-rod 9, which is suitably connected with the other line-wire of the circuit of the present system.
10 is a tube of insulating material surrounding the anode 8 and having a small orifice at its lower end through which the said anode 8 projects into the electrolytic solution in the cell 6, as shown and as usual in the present type of interrupters.
The difierent adjustments of the parts shown in Fig. 2 are the same as in my prior patent, No. 716,583, dated December 23, 1902.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-
In a combined high-frequency interrupter passing through the apparatus, substantially I0 and rectifier of the character herein described, as set forth. the combination of a containing-cell formed of Signed at Chicago, Illinois, this 29th day of aluminium or the like and constituting the December, 1903.
