UNITED STATES PATENT OFFICE.
ALMON B. STROIVGER, OF KANSAS CITY, MISSOURI.
AUTOMATIC TELEPHONE-EXCHANGE.
SPECIFICATION forming part of Letters Patent No. 447,918, dated March 10, 1891. Application filed Maroh 12, I889. Serial No. 303,027. '(No model.)
To all whom it may concern.-
Be it known that I, ALMON B. SrRowGER, a citizen of the United States, residing at Kan sas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Automatic Telephone Exchanges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in automatic, telephonic, telegraphic, and other electrical exchanges.
The object is to provide means whereby a person at one station may make connection with any other station in the system, by the aid of electrical appliances, without the assistance of an operator at the central station.
A further object is to provide means of the above character which shall be reliable and adapted to general use.
With these ends in view my invention consists in certain features of construction and combination of parts, as will be hereinafter described and pointed out in the claims.
The same general plan is adopted as in the systems now in use, in that of having a principal or central station, (central ofiice,) and a number of sub-stations, the said sub-stations being placed in electrical connection with each other at the central ofiice by and through line-wires, which line-wires, for the sake of brevity, will be designated phonic wires, (introducing the ancient obsolete fornn) but differ in that of having, in addition to the said phonic wires, a series of wires (one or more) to operate the hereinafter-described mechanisms located at the central office. At the sub-stations are the appliances which are used to transmit and receive communication, as telephones and keys. At the central office are arranged in methodical order as many switch-cylinders, with their attendant mechanisms, as there are sub-stations. The abovementioned phonic wires trend within the central oifice in close proximity to each cylinder. From each phonic wire and attached thereto wire terminals, connectives, or legs extend to the inside of each cylinder, there being as many connectives attached to each phonic wire as there are sub-stations.
With this brief outline, I will proceed to more fully describe my invention and elucidate its workings by the aid of the accompan y in g drawings.
Figure I represents in a perspective view my invention, showing at a distant sub-station one telephone and its exchange device at the central ofiice, also the mainline wires connecting the central office with the substation. Fig. II represents four of snchdevices as is represented by Fig. I, showing the manner in which the cylinders are connected, also the trend of the electrical current from one sub-station to another through the cen tral office. Fig. 111 is a plan View of a series of cylinders, line wires, and connectives, showing the normal position of the circuitclosers. Fig. IV is a sectional view showing the magnets, levers, and pawls by which the device is operated. Fig. Vis a detail view of the ratchet-wheels and pawls for operating the same. Fig. VI is a sectional view of the cylinders, showing more clearly the construc tion of the circuitcloser and feather-andgroove attachment.
Referring to the drawings by letter, A represents a hollow cylinder constructed of glass, wood, or any other suitable substance which is a non-conductor of electricity, supported in any well-known or approved manner. The cylinders are provided with perforations a, arranged in transverse and vertical rows.
1; represents the wire connections extending from the inside of the cylinder through the perforations a to the main-line wires N and is attached thereto. Their use is to conduct the electricity, when in contact with the circuit-closing needle 0 C, to and via the line-wires N to the desired sub-station. The terminals of said connectives within the cylinder are shown at b, Fig. VI. In this lastnamcd figure the circuit-closing arm is represented in parts, in which C is the circuitclosing sleeve and is firmly attached to the lower end of the sleeve-rod D. \Vithin this circuit-closing sleeve isclosely fitted the cir cult-closing needle 0, held in such a manner as to be in perfectelectrical contact with the wire-terminal b by the spring 0. The rod D, (see Fig. V1,) is located along the axle-' line of the cylinder and is free to rotateand movelongitudinally. The lower end of the the circuit-closing needle 0.
rod D is sleeved, into which is inserted the upper portion of the ratol1et-rod D. This sleeve construction between the rods D and D allows the ratchet-rod D to have a longitudinal motion only, thereby keeping the ratchet-teeth (Z continuously toward its attendant pawl.
The ratchet-rod I) is provided outside of the cylinderA and conveniently below it with a series of ratchet-teeth (l, by means of which the rods D and D are moved longitudinally. The wheels E and E, through the hub of which the rod D extends with a feather-andgroove connection R, (see Fiv. \l,l so as to cause the rotation of the rod D and at the same time admit of its longitudinal sliding movement therein, are provided on their peripheries with a series of ratchet-teeth e and e, by which the rod D is rotated, and with it the circuit-closer C and C.
G 11 I represent levers having pawls g h i pivoted in their ends in position to engage the ratchet-teeth, with which they are respectively in contact. Each lever has a vibratory movement and is oscillated by the alternate energizing and tie-energizing of their respective magnets, thereby imparting motion to its adjacent ratchet-teeth and consequently At each pulsation of the push-button at the sub-station made at the will of the operator causes, through the channels thus described, the circuit-closing needle C to move from row to row and from wire to wire in the row. lVhen only three levers are used, the dog T (see Figs. land II) would be necessary. Its use is ob- VlOllS.
The magnets K K K arelocated in suitable positions that when energized by the manipulation of certain keys at the sub-station, operate their'respective levers. A set of magnets K K K K are also located in suitable positions, that when energized their respective levers P serve to release the pawls from their engagement with the ratchet-teeth and allow the circuitclosing needle 0 O to assume the initial position by the aid of gravity and the spring S. At each sub-station there is a set of keys marked, respectively, G, H, I, and P. Each key is connected by wire with its respective lettered magnet at the centraloffice, and when pressed an electrical circuit is established, it being understood that both ends of the wire are grounded or connected with a return-tap, italso being understood that a battery is used to generate the electricity and may be located at the sub-station between the keys and the ground. The linewire N extends from the telephone to and within the central ofiice, there connected by the circuit-closing connective wire \V to the circuit-closing needle 0, and also by connect ive B to the inside of each cylinder.
Each perforation a of the cylinder A is numbered with respect to an initial or starting point on the cylinder-for example, in rows numbered 1 2 3 4, &c.from the lower end of the cylinders upwardly, and by places in each rowas, for example, 1 2 3 at &c. to the right or left of a given vertical row, so that, supposing there were one hundred perforations in each of the rows, No. 310 would be in the third row from the bottom, ten spaces to the right or left of the vertical initial line.
Each connective wire B and phonic linewire N, Figs. II and III, with which the connections are attached, is also numbered to cor respond with the number of the perforations a, through which the terminals extend.
The person wishing to place his transmitter and earphone in connection with those of another, he will do so by successively pressing or depressing the keys, which cause the circuit-closer O C to move. For example, if telephone 288 wishes to place himself in connection with telephone 315 he will do so by pressing the key marked G" three times, then the key marked 11 once, and then the key marked I five times. IIis circuit-closer C C is then in contact with wire-terminal No. 315. In Fig. II sub-station No. 288 is represented as being in connection with substation No. 315. This is known by the positions of the circuit-closer C of cylinder-No. 288, the course of the electrical current being indicated by arrows. Had its oircuit closer 0 been turned to the next wire indicated in the drawings, 288 would be in connection with 11. The person at telephone 315 will take down his earphone. The two are then able to converse with each other. When conversation is ended, the person calling up hangs up his earphone, depresses key marked P, which causes the magnets K to be energized, attracting the armatures, thereby Withdrawing the several pawls from their engagement with the ratchet-teeth and allow the circuitcloser C C to fall and return to its initial point.
If a person has called up the wrong number, he will push the key marked P and start over again.
The size of the cylinder A will depend solely upon the number of wires required in the system and the distance apart which it may be found most expedient to place them; and it is also evident that various slight changes might be resorted to in the mechanical construction of the several parts which I have described without materially departing from the spirit and scope of my invention, and hence I do not wish to belimited strictly thereto.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a system of telephone, telegraph, or other electrical exchange, the combination, with a series of wires leading to different stations in the system and having their ends insulated and held in curved rows, of a contact mechanism for moving the needle from row to row, mechanism for moving the needle along the row, magnets for actuating said mechanisms, and wires leading from a substation for conducting electricity to energize the said magnets, substantially as set forth.
