Application filed April 15, 1910. Serial No. 555, 02.

Improvement in Combined Auxiliary and Automatic Fire-Alarm Systems, the following is a specification.

This invention relatesto an electric supervisory signal-system. 1

It comprehends essentially thecombination of anauxiliary fire-alarm and an auto-- mat-ic fire-alarm system.

' An auxiliary fire-alarm, as ordinarily con-.

of which structed, comprises essentiallyan electriccircuit auxiliary to the firehlarm g;ircuit,

and arranged throughout a building on other a property to be protected, and is connected to the starting-magnet of a fire-alarm box in said fire-alarm circuit, and has signalingdevices arranged throughout the building,- adapted to be operated incase of a fire to, cause said starting-magnet, to release or otherwise operate said fire-alarm box to send its signal to the fire department.

An automatic fire-alarm usually comprises thermostats arranged throughout the building, or other property to be protected,,adapted to operat-e'a circuitecloser for an electriceircuif and cause a signal to be sent.

The essential object of this invention is to provide an auxiliary fire-alarm system, having an auxiliarized fire-alarm box and signaling-devices for controlling its operation, with automatic signaling devices adapted to we operated by thermostats, sprinklers, and other devices, and to provide'c ode-signal transmitting means adapted to be operated by said automaticsignaling devices, exclusi ely ot the auxiliarized firealarm box, whereby automatic fire-signals and other automatirally-operated signals are sent to a supervisory-station,where inspectors are in attendance. Also to provide other means for operating said code-signal transmitting means by the signaling-deviceswhich are employed for operating the auxiliarized firealarm box. whereby the fire-signals are likewise sent to the supervisory-statlion.

The invention also has for its objectto provide the mechanism which is responsive to the operations of the automatic signalingdevices, with time-controlled means, where by it-will not respond to a quick operation of said automatic, signaling-devices, such, for instance, as might be produced by a sud.- den jar or blow, or any accident.

Figure 1- is a diagram of a circuit of a system embodying this invention, Fig. 2 is nism adapted to respond to the operations of the automatic signaling-devices for controlling the operation of a code-signal transmitter, Fig; 3 is a detail of a portion of the signal-controlling mechanism shown in Fig. 2, in position to close the circuit of the starting-magnet of the code-signal transmitter.

Theauxiliary-circuit. here shown, see Fig. l, for the purpose of illustrating this invention is a modification of a well-known type. and comprises essentially an open circuit having a heavy battery and one or more open branches at one side-oi" said battery, and a closed loop at the other side of said battery. a represents the heavy battery; u, ar the circuit-wires of the closed loop at one side ofsaid battery; and a a circuit-wire leading from the other side of said battery, which has one or more open branches ah A small battery a may and preferably will be arranged in the closed loop for testing purposes. The closed loopis extended through out. the building,'or other property, to sev eral fire-signal stations 6, and also to an auxiliarized fire-alarm box a, the starting magnet- (17 of which is contained in said loop. The auxiliarized fire-alarm box has its sig naling-devices connected in a tire-alarm cirto the fire-department.

At the several auxiliary fire-signal stations 1), a represent pivoted switch-arms normally resting on plates a, and arranged .in series in the closed loop. The severalopen branches a of the-auxiliary-circuit also ex-. tend to the-several auxiliary fire-signal stations 6, and are connected to plates a arranged close to the plates (1 so that the switch-arms a may 'be readily moved from plates (1.. The switch-arms a and plates a, (1- constitute the fire-signaling devices. and said signaling-devices 'are manually operated, and, when operated, the closed loop Patent-ed Apr. 15, 1913..

will be opened, and that side of said loop containing the starting-magnet a of the auxiliary fire-alarm box will be connected to Y the open branch leading to the plate a as- 5 sociated with the switch-arm which is operated. The heavy batterya will be included in the circuit thus formed, and the starting-magnet a caused to release or other wise operate the auxiliarized fire-alarm box. In case the usual small battery a is employed in the closed loop, it will preferably be arranged with its poles disposed the same as the poles of the heavy battery a, so that,

Throughout the building automatic firesignal stations are arranged, and also, if desired, other automatic signal-stations. As here shown, they each have an automatic sigtheir combined energies will be naling-device, such as circuit-closer t and t9", adapted to be operated by a thermostat, sprinkler, or other device, and each circuitcloser is arranged to connect together a pair of circuit-wires I2 72 one, as 6 leading from the closed loop of the auxiliary-circuit, preferably from one side of a fire-signaling-device and through a resistance-coil bfiand the other, as 6 leading from a branch afof the auxiliary-circuit, preferably from the plate a, which is electrically connected with the plate a at the other side of said fire-signaling device. \Vhen any one of the automatic signaling-devices is operated,.one ofthe open branches a* is connected with the closed loop, forming a 4 closed circuit, as follows: Battery a, circuitwires a a, 6 automatic signaling-device t, circuit-wire 6 to the closed loop, where the current divides, the larger part going through the path of low resistance by circuit-wire a, to battery. Thus a section of the closed loop and some one of the branches of the auxiliary-circuit is utilized when operating any of the automatic signaling-devices. If one of the sections of theclosed loop should be broken at the moment the signaling-device t is operated, the other section will be utilized to form a closed circuit. The resistance b, which is included in the circuit formed by the operation of an automatic signaling-device, as, for instance, in branch-wire 6 is suflicient to allow but a small amount of current to flow through the circuit, so that the starting-magnet a ofthe auxiliarized fire-alarm box will not be operated to start said box, eventhough the section a of the loop should be broken, and-the section a of the closed 100 the only one included in the closed circu t formed by the operation ofvthe automatic signaling- 'device.

The signaling-devices are designed-to control the o eration' of si ale-receivin appaas a reco'r erfiand ag'be l, at, a

supervisory-station 100, where the super- VlSOIS are m attendance, and means are herein provided for sending to said supervisory-station two different signals, one controlled by the fire signaling-devices, and the other-controlled by the automatic signalingdevices. For sending these two signals codesignal transmitting means such as shown in my application for Letters Patent, Ser. N 0. 555,605, filed April 15,1910, may be employed, but my invention is not limited to theemployment of said means, as it is chvious that, so far as this invention is concerned', any other suitable code-signal transmitting means may be employed. The particular form of code-signal transmitting means shown in my said application con-' sists of a multiple code-signal transmitter, and sends its signals over the supervisorycircuit 101, to the supervisory-station 100.

Referring to Fig. 1, m represents the signal-wheel of the code-signal transmitting means which is adapted to co-act with a signal-key m, and to be revolved to send a code-signal representing an identification number of a supervised building, preferably with difi'erentiating signal-impulses. The identification number four times sent, with differentiating signal-impulses between them, designates an automatic fire-signal; and five times sent, with pulses between them, designates an auxiliary fire-signal. This signal-transmitter is adapted to be electrically started and controlled, and, for such purpose, a starting-magnet m," is employed for releasing or otherwise operating it, and also for controlling its operation to cause the different signals to be transmitted. Said starting-magnet m is connected in the circuit of battery d, and said circuit has several branches containing circuit-controlling devices, arranged to separately control the operation of the startingmagnet to release the signal-transmitter to transmit the different signals. One of these local circuits is controlled by relays b in the branches of the auxiliary circuit, which are responsive to the operation of the automatic signaling-device's, and also to the operation of the fire-signal devices. The armatu-res b of said relays are connected with a circuit-wire (i which is connected by circuit-wire d with the battery 0?, and the con-- tacts-d which are engaged by said armatures when attracted,'are connected by circuit-wires d :with a circuit-wire d, which is connected to the armature a of a relay a, which is arranged in the open branch of differentiating signal-imthe auxiliary-circuit, said armature being normally retracted and' engaging a contact a connected with a circuit-wire d which is connected by acircuit-wire d with the battery (Z. The circuit-controlling device controlled by said local-circuitis designed to control the starting magnet m operfire-signaling devices is momentary and the fixed stop I on the frame, and the other arm,

operation of the automatic signaling-devices permanent, the circuit controlling device which is operated by the electro-magnet t is of a' slow responding character, so that the diiierence in time or continuation of the closureis utilized to causeits operation, andin turn to control the circuit of the startingmagnet m ptthe signal-transmitter to send the automatic signal. Said delayed or slowresponding cirwit-controlling device comprises a pair of normally open contacts 0' adapted to be closed only upon a prolonged closure of the circuit of the elect-ro-magnet If, and when operated, will close a branch: circuit of the starting-magnet. m as follows: battery (Z, circuit-wires d, d? starting magnet m circuit-wires d ,and o leading to the delayed or slow responding circuit-controlling device, circuit-Wires 7 and (F, to battery.

Referring to Figs. 2 and 3, a clock-train or other timed controlling-deviceis employed for controlling the operation of the slowresponding circuit-controlling device, hence said circuit-controlling device is referred to as time-controlled. The armature t of the pivot-shaft fi, and is normally held in retracted position by a rctractile-spring t. A bell-crank lever is also secured to said pivotshat't 2, one arm, as Z" of which bears. an adjustable stop-screw i adapted to engage a as t, of which is connected by a spring 6' with an arm 22 pivoted at If. Saidarm and lever are normallyheld separated by an adjustable-screw. The armature, when attracted, pulls upon the spring t and thereby moves the arm t. Thus the armature is flexibly connected with the arm 25 The arm 6 is loosely connected by a link i, with an arm t, to which is rigidly secured a pawl t and said arm and pawl are pivotally. connected at t" to a weighted pawlcarrying plate t, loosely mounted on a shaft of a timing-mechanism of any suitable construction. This pawl if is movable into and out of engagement with a ratbhet-wheel t,

' secured to a shaft of the timing-mechanism and revolved continuously by it. In order .to'insure a proper disengagement of the pawl and IZttOliQt-Wh eel, an arm Z is rigidly connected with the pawl and arm 6 and said arm 27" engages a-fixed pm 2 on the t'rame when the armature is retracted which serves as an abutment, so that as the arm 25 is'moved upon attraction of the armature, it swings about the fixed pin and moves. the

pawl into engagement with the ratchet wheel' and also moves the weighted pawl-carrying plate. When the armature of, the magnet 15' is attracted,the first movement of the arm 13 moves the pawl i into engagement" with the ratche-t-wheel, and then said pawl and the arm 6 will be permitted to move with it, but only as fastassaid ratchet-Wheel is operated by the timed-mechanism. It the armature remains in its attracted position,

the arm 25 will continue to move until a detent-lever t, rigidly connected. with said arm 25 disengages a lever t, pivoted at 15 Said lever 6, when released, is moved by a. spring t connected with it. A ccn-.

tact operating-lever t is rigidly connected with said lever and when permitted to operate upon release of. the lever t will engage the contact pens 0 and close the circuit. Thus it will be seen that the circuitabout on the floor above a thermostat, and

is not atlected by a water hammer upon the devices used in connection with a sprinkler system. To restore the operating-lever 25 to normal, a restoring-arm t is provided which is pivoted at and has a pin 15 adapted to engage said lever and said restoring-arm has an extension to which a rod t is connected, and upward movement of said rod, by a manual operation, operates to move the arm 29 and restore said operating lever and also open the time-controlled circuit-controlling device 0. When the timecontrolled circuitcontrolling device 0 is closed,the armature of the starting-magnet we) will be moved into its attracted position and held until. the circuit includingsaid elec- -tro-magnet 15 is opened, and this is accom-' controlling device 0 is closed only upon a has been sent. A relay a is herein provided for disabling the local circuit of the automatic signaling-devices when the fire-signalingdevices are operated, and also upon the occurrence of a cross between the open branches and closed loop of the auxiliarycircuit, thus preventing the sending of an automatic-signal. Said relay is responsive only to the heavy current employed for o-perating'the starting-magnet of the auxil- &

signaling-devices.

It is desirable that the manual operation o-f-any of the fire-signaling devices in the auxiliary-circuit, and which are adapted to operate the auxiliarized fire-alarm box, shall also cause a signal to be sent to the supervisory-station, to thereby notify ,the supervisors at said station-bf the manual operation of the auxiliary-circuit at the super- 'vised building, and, consequently, the auxiliarized fire-alarm box cbnnected therewith for fire. For the purpose of carrying out 4 this feature of my invention a relay a may be employed, which is included in,the closed loop ofthe auxiliary-circuit, inseries with the starting-magnet a of the auxiliarized fire-alanmbox. 'The armature a of this relay normally occupies a semi-attractedposition. Whenever any of the manually-operative fire-signaling devices are operated and the starting-magnet of the auxiliarized fire-alarm box thereby caused 25.-to release said box, the armature a, of the relay. a 'will be moved into its attracted position and the circuit-controlling device a 5 (1 closed. .Said circuit-controlling"device a a yis connected in branch ciictiitgo'wires; (Z a, d, of the circuit of the battery cl, and, when closedithe circuit of the p I p H starting magnet m s c osed to cause said magnet-.to release the supervisory signal-.

. magnet m will be held in its attracted position until the circuit, including said circuitcontrolling device, is opened, and, to accomplish this result, another signal determining device operated by the supervisory signaltransmitter is employed for opening this circuit. Such si nal determining device comprises a switc -opening device operated by the transmitter and adapted to operate a switch 70 when the signal-transmitter has operated to transmit the fire-signal, which signal maybe the identification number five times repeated, in conjunction with diiferem tiating signalimpulses between each repeti- 7 before referred to. v

.If desired, a local signal-recorder of-any suitable construction may be provided at the building" containing the signaling-devices, and, as here shown, theoperatin :m agnets c of such a recorder are represeiied in diagram, Fig. 1, which are included in branchwires 03", so as to be controlled by the-armation, as shown in my application #555,605-
