SPECIFICATION forming nartof Letters Patent No. 543,106, dated July 23, 1 895. Application iiled July 2, 1886. llserialNo. 206,978. (No model.)

To @ZZ whom t may concern.:

. Be it known that I, CHARLES E. SCRIBNER,

a citizen of the United States, residing at Chicago, in the county ot' Cook and State of 5 Illinois, have invented a certain new and uscful Improvement in Village Telephone Sys` tems, (Case No. 103,) of which the following Vis a full, clear, concise, and exact description,

reference being had vto the accompanying Io drawings, forming a part of thisspecilication.

My invention relates to telephone systems, and is especially designed for use in towns where there are not enough subscribers to make it profitable to employ an operator to I5 do the switching. y

No central-office'switchboard is employed in my system, but the outfit at each station lis so arranged that any subscriber may connect with any of' the lines.

My invention consists in the circuits, signaling apparatus, and switching apparatus, whereby a subscriber may while signaling temporarily introduce his bell into the line of any other subscriber, said bell being automatically brought again into its own Circuit after the signal has been sent, so as to be in position to respond to any other call.

My invention Vis illustrated in the accompanying drawings, in Which Figure lis a diagram illustrative of' the circuits of' two telephone-lines, the telephone outfit of one of said lines being shown in detail, dotted lines indicating that the stations represented by the switch-sockets are sep- 3 5 arate. Fig. 2 is asectional view of the switch for temporarily including they subscribers bell of any station in the circuit of any other of the lines passing through said station.

Fig. 3 is a diagram illustrative of the circuits 4o between three subscribers stations.

At each station I provide a separate loopspring-jack switch for each telephoncfiine ot' the system. By means ofaloop-pluginserted in the proper switch the telephone outfit at any station may be looped into any one of the lines.

The circuits and connections of the bell at each station are so arranged that the bell will normally be included in the circuit of 5o the particular line upon which calls are sent to theparticularstation. By means of aloopswitch this bell may be brought temporarily into the circuit of any other line with which the outfit may be connected, so that calls may be sent and received over said other line.

In Fig. l the line a is shown grounded at its different ends, the telephone outfit being connected therewith by the loopaz. This outfit `consistvs'of the loop-plug d, which is shown inserted inthe spring-jack switch of 6o the line a3, the bell e, and the loop-switch h for disconnecting bell e from its lnormal circuit with loop c, so that it may be tempora rily included in the circuit of any other line with which plug d may be connected. The 55 telephone, the transmitter, the telephoneswitch, and generator ofthe outfit require no special description. The subscriber at sta tion of line ct bysimply inserting the plug d of his outfit in the spring-jack switch of 7o another line passing through his said station may loop the two lines together. Thus line of and line a3 are shown looped together by the loop-plug d, inserted as shown. In Fig.

3 at station l, I have shown'the plug d of said 75 station inserted in the switch of said line 0,3, which is the position assumed at stationl when a call has been sent from some other station to said station l. In this instance it is assumed that the subscriber at station 3 8o has called up station 1, and stations I and 3 are thus shown telephonically connected.

It will be observed that by pushing up the handle of loop-switch h the Abell e may be disconnected fromits normal connection with the loop 0.2 of line ct', and included temporarily in the circuit of any other line with which plug d may be connected-as, for exam: ple,with lineas. As shown in Fig. l,the loopswitch h is in position to bring bell e into the 9c circuit of line ct. This loop-switch may be placed upon the lid of the box or in any other convenient position.

It will be seen that the sliding piece la of the switch may consist of a piece of rubber or other insulating material, ou which are placedthe contactpieces Z, m, m', anda. The springs o o mounted on the rubber strip p are looped into the circuit of the generator. The springs q q are looped into the circuit roo of the line a. These springs are mounted upon the rubber strip r, which is provided with a hole which serves as a guide for the handle s, which is connected with the slide L. The slide is held down in the position shown by the spiral springs t t. In the posi tion shown, o o rest upon the metallic strip or contact-piece Z, thus closing the loop containing the generator. The springs g q rest upon contact-points m, m respectively, thus bringing the bell into the circuitof the line ct.

It will be understood that at each subscribers station is placed a spring-jack switch of each of the othcrlines of the system, as shown in Fig. 3.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. Telephone lines each extending to each of several stations, each of said stations including an outfit consisting of a telephone set, a bell and loop switch therefor, the said loop switch normally bringing said bell into the circuit of the particular line of the station, in combination with a looping device connected with the bell and its switch at each station, whereby the bell of any station may be temporarily included in the circuit ofany line of the station other than the onein which the bell is normally included.

2. The combination, with telephone lines, each including normally the bell of one or more stations and each line connecting with a different loop spring jack switch at each station, of a loop switch and calling apparatus at each station whereby the bell may be disconnected from the line in whichit is normally included and brought into the circuit of either of the other lines and any station ot' the system put into telephonie communication with any other station.

3. The combination with a number of telephone lines extending to a sub-station, of a bell normally in circuit with one of said telephone lines, a generator at said substation adapted to be looped into circuit with any one of said telephone lines, and a switch for removing.,r said bell from the line with which it is normally in circuit, and for connectingr said bell in circuit with said generator; substantially as described.

In witnesswhercofl hereunto subscribe my name this 21st day of June, A. D. 1886.

GEORGE P. BARTON, JOSEPH S. KENNAR'D, Jr.
