UNITED STATES @ATENT FFICE.
ORMOND F. CASSADAY, OF CHICAGO, ILLINOIS, ASSIGNOH TO KELLOGG SWITCHBOARD AND SUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
IN'IEBRUPTER CIRCUITS.
Application filed May 21, 1919.
To all whom it may concern:
Be it known that T, ORMOND F. CASSADAY, a citizen of the United States of America, and residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usei'ul Improvements in Interrupter Circuits, of which the following is a specification.
My invention relates to interrupters and has to do most particularly with interrupters of the type which are used in con nection with composite telephone and telegraph systems for signaling purposes.
Interrupters as used in systems of the above type are difiicult to keep in adjustment and it is one of the essential features of a system of the above type to deliver a signaling current which will not interfere with the ordinary telegraph signals. Interrupters of the present type get out of adjustment and the current thus delivered from an interrupter out of adjustment produces trouble in the system.
An object of my invention is the construction of an interrupter and circuit of a type for use in connection with composite circuits which will remain adjusted and deliver a steady frequency of current and at the same time be simple in construction and its parts readily accessible and cheap to manufacture.
A feature of my invention is the adoption of an interrupter relay in association with an induction coil, a retardation coil and a condenser to produce a character of high frequency current, particularly adapted for use in circuits of the above character, although I do not wish to be limited to the same as my invention is applicable for other uses.
The novel features of the invention through the provision of which the above mentioned and other advantageous results are attained will be explained by reference to the accompanying drawings, in which like reference characters in the several views denote like parts, and in Which- Fig. l is a plan view of the interrupter of my invention with the cover in section to clearly illustrate the apparatus, and
Fig. 2 is a diagrammatic circuit arrangement operating in connection with the interrupter of my invention.
Referring now more in detail to my invention as illustrated and referring to Fig. 1,
Serial No. 298,764.
it comprises a base or mounting plate 2 of any suitable material upon which the apparatus of my invention is mounted. An interrrq'itcd relay IR is provided, comprising an electromagnet 3, heel iron 4 and pivoted armature a pair of interrupter springs ('3 and 7'. A tensioning spring 8 associated with the springs 6 and '7 has its free end engaging the interrupter spring 6. The inter rupter springs 6 and "I and tensioning' spring 8 are mounted upon the heel iron 4: by means of the screws 9, which screws 9 have screw threaded engagement with suitable tapped openings in the said heel iron. The arma true 5 when attracted, due to the energization of relay IR, opens the interrupter contacts 6 and 7 in the usual manner for purposes as will be more fully hereinafter described. One end of the core of the relay is tapped and receives a screwthreaded mem ber 70. The screw-threaded member is provided with a knurled portion so that the member 70 may adjustably be moved outwardly and inwardly to regulate the length of stroke of the armature 5. A spring 71 is provided for holding the member 70 in its adjusted position.
The relay IR, as a whole, is supported upon an angular bracket 10 and secured thereto by means of nuts 11, which nuts have screw-threaded engagementwith the threaded portion of the core oi the electromagnet coil 3, and the bracket 10 is in turn secured to the base 9 by means of the screws 12. A condenser 13 is provided and is secured to the base 2 by means of brackets 14 and 15, which brackets are secured to the condenser 13 in any suitable manner, and the brackets 1 1 and 15 are in turn secured to the base 2 by means of screws 16. A retardation coil lll) is provided and is secured to the base 2 by means of screws 17, which pass through suitable openings in the heads 18 of the retardation coil RD and screw into the base Terminals 19 are also provided for the retardation coil RD and are supported upon the heads 18 and secured thereto by means of the screws 20. An induction coil 1C is also provided and is secured to the base 2 by means of the screws 22, which pass through suitable openings in the heads 23 of the induction coil IC and screw into the base 2. Terminals 2-1 are provided for the induction coil 1C and are secured to the base 2 by means of the screws 25. A prothe second winding of said retardation coil being connected to the other arm of said delivery circuit, thus placing the windings of said retardation coil and the secondary winding of said transformer and the delivery circuit in series relation.
3. An interrupter circuit of the class described including a source of current, a transformer including a primary and a secondary winding, an interrupter relay serially connected with said source of current and the primary winding of the transformer, a switch controlling the circuit of said. interrupter relay, a coil bridged across the contacts of said interrupter relay, a retardation co-il comprising a pair of windings, a delivery circuit, a circuit connection from one terminal of a winding of said retardation coil to a terminal of the secondary Winding of said transformer, the other terminal of said Winding of said retardation coil being connected to one arm of said delivery circuit, and another circuit connection from a terminal of the second winding of said retardation coil to the other terminal of the secondary winding of said transformer, the other terminal of the second winding of said retardation coil being connected to the other arm of said delivery circuit, thus placing the windings of said retardation coil and the secondary winding of said transformer and the delivery circuit in series relation, and a condenser bridged across said delivery circuit between said secondary winding of said transformer and the windings of said retardation coil.
Signed by me at Chicago, in the county of Cook and State of Illinois, this 19th day of May, 1919.
