,To all whom t may concern.'

Be it known that I, Louis liiiLLEn, of Rochester. in the county of Monroe and State ot' New York, have invented certain new and useful Improvements in Electrical Communicatingr Systems; and I do hereby declare the following to be a full, clear, and exact descril'ition ot the same. reference being had to the accompanying drawings` forming a part of thisA specification. and to the rcterenwnumerals marked thereon.

The present invention relates to electrical communicatiner systems and it has for an object to provide a system over which either lire alarm reports or calls may be sentor telcphonic communications may be maintained. preferably having provision for giving preccdcme to the tire alarm reports.

Another object of the invention is to provide atelephone system in which the time of the call from a substation is automatically recorded in order that the system mayv be f iployed for making records ot' the times of the reports of policemen, watchmen and others who are required to make periodical returns to central oliices.

still further object is to provide. a tire alarm system in which the sender of the alarm or call may be signaled that the alarm has been received and in this way assured that the system is in working condition.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described. the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a diagrammatie view of one line of a telephone system designed for recording the times of the reports of policemen or Watchmen, there being combined therewith means adapting the line for the transmission of fire alarm signals; Fig. Q is a diagrammatic view of the central oliiee apparatus for connection to the line; Figi. 3 is a detail view of one of the time recording,Y mechanisms, and Fig. 4 is a diagrammatic view of a line in the system desi ned for use in a factory or other large bui ding or plant in which a watchman or watchmen travel from station to station and report at cach station, the report being automatically recorded in the building and also at some central point, such as a telephone oiee or police station.

In the embodiment of the invention illustrated in Fig. 1 each line is preferably a normally closed circuit having a substation and a central station and comprising line conductors 1 and 2 and a suitable source of energy, such as central station battery 3; a high resistance comprising in this instance resistance coil L'l and the windings of a signal or electromagnetic bell 5, being preferably arranged in the circuit.. Bridged across the circuit in order to short circuit the high resistance is a telephone instrument set comprising a transmitter (i connected to the lines 1 and 2 by a conductor 7 having a primary coil S therein acti-ing on the secondary coil 9 which is connected to the receiver 10, the receiver being preferably supported as usual upon a hook l1 which controls switches l2 and cuts out the instrument set when the receiver is arranged on the said hook. The branch in which the instrument set is positioned may also be provided with switches 13 which have a normal tendene)v to close and are controlled by the door 14 of the inclosnre 15 thaty houses the instrument set and is pref crably locked so as to be accessible only to authorized persons. It is apparent that when the door 1l is moved to closed position the switches 13 will be moved to break the shunt circuit 7 thas cutting! outv the instrument set. The advantage of this arrangement is that the signal 5 may be operated from the central station in a manner to be described. even though the receiver 10 has not been returned to its hook 11 through either design or carelessness. Arranged Yat the central station to be operated on the removal of the receiver 10 from its hook is, the operators signal or supervisory, which in this instance. embodies a conductor 16 leadingr from line wire 1 to the lamp 17 and a conductor 1F. leading; from the lamp and connecting with a movable switch member 19 that is adapted to crepe/rate with Contact Lt) oonnvvtvtl hy oontlurtor l with the Contart- 'vl'hv vontuvt 2; is adapted to be vngagvtl hy tho arnnuurv witvh Q3 which, hy votnllulor 2l. ronnvvl with .liltv wir@v 2. l Yl`hv opvrat'iou ot thv armaturv myitvh 2?) may hv vtlvvtvfl hy onv polv ot' thv compound wound vlvctrounagnvt '13.3 whosv wintlingrb urv arraugvtl in thv inuinlinv.

The lever 53 may be arranged CD i other and reports at each station. ln reporting he removes the receiver l() which closes switches 12 and cuts out the high resistance 4. 5 thus energizing` electromagnets 25 and 4t. The lat'ter actuates the time recording mechanism making a punch mark in the in 'tains from the voice of'the sender whether the oroper person is making the report. ln coi .ecting with the line the central operator au;I unatically extinguishes the lamp 17 and if the otlicer desires to connect with another line the plug 38 is en'iployed, the denergization of magnet causing the lamp 17 to be again 'illuminated to notify the central operator that the conversation has ceased. If the otiieer tails to hang up the receiverl when he closes the door 14 the telephone instrument set will be cut out by the switches 1?, thus permitting the substation to be called. The calling of the substation is etliected by the generator which connects with the line after the recording mechanism and the operator's supervisory has been cut from the line.

The tire alarm signalv may be sent by any one upon breaking' of the plate 59'. and pushing' of the button 5S. This breaks the normally closed line circuit and deiinergizes the magnet (33 which releases the signal (50. The resistance -l. is yat the same time short circuitcd thus illuminating the lamp 1T and operating the recording mechanism. The central operator thereupon presses bu ton #i3 to release switch 53 and operate the signal 5 at the substation in order to notify the sender of the alarm that the call has been noted. The button 5S could be used for some other purpose than a fire alarm call as it may he employed to permit private individuals to'call the police.

'hen the system is arranged in a factory or other plant the operation at the central station is substantiallv the same. The removal of a receiver also operates a record.- ine mechanism at the factory so that a complete record of the reports of a Watchman or watchmen may be obtained at any time while there is at all times a supervision being maintained at the central station.

A system constructed in accordance with this invention will add materially to the etti` ciency of a police force of a. large city as a complete record of each otiicer may be obtained with very little trouble, as each otticer on the line has an individual record, or in other words, one which is separated from tno others. t Any number of reports may be sent in simultaneously withoutinterference,

as each substation has a separate connection with the recording mechanism.' The approximate location of an otficer at' a particle lar time can be found out immediately and he may be called to headquarters merely by signialingir the last substation at which he has reported or the one at which he is next to report. It is impossible for the officer to send in a report by another party as he must talk with the central operator who will be familiar with his voice. The central operator cannot interfere with his report favorably or otherwise as the recording mecha nism is controllable only from the substation and the report is made Whether the operator answers or not. The otlicer cannot offer as an excuse for his failure to report that the line was out of Yorder when such is not the case for on the breakimgr of the line the central operator is signaled.

The fire alarm feature may take the place of the usual fire alarm system or may be used in conjunction therewith when it will offer that much tereater security against the spread of fires. Even should one of the lines get out. of order the whole system is not rendered inoperative as with the present fire alarm systems and `the sender of the alarm is assured that the report has been received as he obtains a signal from the central otlicec lYhen the factory system is employed it is possible to maintain constant supervision of the watchmen for should they fail to re.

port to the central operator immediately int quiry is instituted to ascertain the reason therefor. Thilo the central operatorl cannot know from which substation the report is sent in yet it can be ascertained by an inspection of the auxiliary recording mechanism whether the usual rounds have been made.

vhile the initial cost of this system is not greater than those at presentl used. the cost of maintenance is less, and the 2greater etlieicncy secured both in police and in tire protection soon pays for its installation.
