Applicationled June 25, 1825. Serial No. 38.520.
This invention relates to new and useful improvements in fire-alarms,l and particularly to {ire-alarm systems.
@ne object of the invention is to provide a system for a house, tel, office building, or the like, wherein an udible signal and a visual signal are given upon the breakingout of a fire, to notify the occupants thereof.
Another object is to provide a system of this character in which audible visual signals are given, within the premises, upon the breaking out of a fire, subsequent audible and visual signals being given when the re has gained slight headway, the latter signals being given without the premises, and a further signal given at a lire call stat-ion, so that the person at such station may establish telephonic communication with, and accurately locate the point of the fire.
A further object is to provide a system wherein thermostats, of double acting type are used and which will'operate in one direction, upon the breaking out of a fire, to cause visual and audible s1 nals to be given within the premisesand will operate in another direction, upon the fire advancing to adegree, to causeaudible and visual signals to be given on the exterior of the premises, and also at a fire call station, so that the operator at the station may, upon removing a telephone receiver from its hook, automatically establish telephonie communication with the location o the tire, to receive notification, thrpugh the medium of a phonograph, as to the exact location of the trou- Briey,the invention comprises a series of double acting thermostats, arranged at diiferent points in a building, and in circuit with audible and visual signals, located, both within the building and exteriorly thereof. A telephone transmitter is located in the building and is in circuit with a telephone receiver, located at the tire call station, or' fire engine house. A phonograph is associated with the telephone transmitter, and
' has a record which tells of the location of the building. Upon breaking out of a fire, the heat will cause the nearest thermostat to operate to close a normally open circuit, to light a lamp and ring a bell, within the building, to give an alarm to the occu ants yof the building. Should the lire gain eadway, or intensity, the greater heat will cause telephone receiver, and at the same time start a motor which, causes the grapfhophone to operate and deliver the message, of its record, into the transmitter, such message being heard at the station, with the result that the station operatives will knowv the exact location of the fire.
The drawingqshows a diagrammatic view of the fire alarm system, and includes the fire call station, and one subscribers station.
Referring particularly to the accompanying drawing, l() andll represent the main line wires of an electric lighting system. The fire call station is indicated as a whole, by the letter A, and the subscribers station by the letter S.
In the subscribers station, which may be a private dwelling, an otlice building, hotel,
or the like there is located a telephone transmitter '12, which is covered by one end ot an amplifying horn 13, andconnected to the other end of the horn is the tone arm le, of a graphophone l5. A turntable lt, on which is placed a record l?, is located in position to be engaged by the needle ot the soundbox 18, of the tone arm, said turntable being arranged to be driven by the electric motor 19. it a suitable point, adiacent the graphophone, is a transformer `20, the primary winding of which is connected to the main line wires l() and ll, by means of the wires 21 and 22, while wires 23 and 2t lead from the secondary winding of theatransformer, the former being connected with the electric motor 19, and the latter to a line wire 25, to which reference will be' made later herein. At diiferent points in the subscribers station are arran d thprmostats 26, which are oi the doub e acting type, that is, when subjected to a moderate heat will .operate to close one circuit, and when the coil by the spring 35.
Subiected to a greater heat Will operate to close 4another circuit. rllhree line Wires 27, 28, and 29 are used in the system, the Wire 28 being used as the neutral line. lln the subscribers. station there are located the signal bell 30, and the red signal light 31,
one side of the bell and the light being contact 36, While the other end is normally held out of engagement with a contact 37, said Contact being connected With the Wire 38,
which leads to and is connected with one side ot the telephone transmitter 12. A second Wire 39. is connected with the telephone transmitter, as shown. A second transformer 4:0 is located Within the subs"ribers station, and has its primary connected with the magnet coil 33 by means et the Wires 4:3 and al, and arranged in parallel in this circuit are the belll and lamp a6. rllie Wire t, however, leads to the coil 33 by means et the circuit Wires 23 and 29, through the thermostat 26 lin the hre call station A there is located an automatic switch D, which includes the magnet coil 51, and the pivoted armature V52. The Wire 25 is connected With'the winding of the coil 51, while a battery'53 is connected-vvith the other end ot said Winding. A. Wire 54': leads from the other side oft the battery 53 to the armature 3a, of the switch C. A transformer 55 is located adjacent the switch D, and has its primary winding connected vvith the lines 16 and 11, by means ot the Wires 56 and v57. The Wires of the secondary ot the transformer 55 lead toI a contact 56, and to the pivot ot atelephone receiver support 59, respectively, a bell 69 and lamp 61 being arranged in parallel in' this circuit. From the pivot ot the armature 52 there entends a yWire 62 which has a Contact 63 arranged in position to be engaged by the inner end ot the receiver support 59. Ill'he contact 53 is located in position to be engaged by the armature 52, when the coil 51 is deenergized, and said armature moved therefrom by the springtil. From the Wire 5l a Wire 65 leads to a contact 66 which is located in position to be engaged by the lower side et the end ot the receiver support 59, which engages with the contact 63. Adjacent the support 59 is a battery 67, and connected with one side ot this battory is a Wire 39, leading tothe transmitter l2, the other side having a Wire 6 3 which is'connected `with, the telephone receiver 69. lrom the pivot ot the support 59, to the ternera of hre in the building. lit desired, an an-.
nunciator may be arranged in this circuit, with a View to showing the exact location of the hre. Should the tire gain headway betore anyone can locate it, or should no one be in the building at the time, the thermostat will operate tofclose the circuit through the switch C, so that the magnet coil 33 vvill be energized, thus setting the bell t5, and the lamp t6 `into operation on the outside et the building, whereby to attract the noi tice of passersby, who might send in au alarm. 'lhe arma-ture 3d will be attracted by the coil, thus Vbreaking the closed circuit 25-5l, at 36, and causing the engagement ot the armature 34C with the contact 37., Upon breaking ot the circuit the magnet 51 will become deenergized, permitting the armature 52 to ybe drawn, by the spring 6a, into engagement vviththe contact 58, with the result that the lamp and bell 61 and 69, in the4 hre call station, will op crate to notify the firemen thatA there is a hre. Everything is thus set tor the person in the lire call station to receive a message telling of the exact location ot the tire. `Upon removing the receiver 69 from. the support 59, said support will rock on its pivot to move away from the contact 63, and engage with the contacts 66 and 71., immediately upon this circuit being conipleted, current will i'lovv through the motor 19, causing the same to rotate the turntable 16, and the message ot the record 17 to be transmitted through the transmitter 12, to the receiver 69. Current doves :trom the battery 67 through the wire 39, the transmitter 12, Wire 38, armature 3d, by means ot contacts 36 and 37, Wires 5t and 65, support 59, receiver 69, bach to the battery,
'lhe rst signal is produced by the hell 36 and lamp 31, in the local circuit of the batte@ 32, when the hre starts, to notify the oupants of the presence ot tirea lFhe vsecond call is produced when the ltire heu comes hotter and operates the thermostat to signal by means ot the bell t5 and lamp d6, and at the same time set the system ready for telephonie communication withy the hre call statione Uponrenioval of the telephone receiver 69, in the hre call station, the graph- @phone is set in motion to transmit its inessage tothe listener at the hre call station1 Properly connected in the lines27, 23, and 29, is a three-point switch 73, .vvhich is l mi llll
