ORLEANS, IN DIANA ELECTRIC BU RGLAR-ALARM.

. SPEGIFICATIO J Y forming part of Letters Patent N 0. 665,801, dated January 8, 1901. V

Application filed April 2, 1900.

Beitknown that I, JOHN W..ROUGH, acitiin the county, of Orange and State of Indiana, have inventednew and useful Improvements in Electrical-Burglar-Alarms, of which the following is a specification. "This. invention relates to new and useful mprovements in -.electrical burglar-alarms;

' is to provide a device'wherebya burglar cause the transmission of an audible signal through the medium of a'telephone system to parties atdifierent points, who may be in communication with the police department.

Afnrtherobjectis to provide means of novel constructiomwherebya likeness of the intruder will be automatically secured.

While the invention is adapted to be used in thepatent to George 0. Halo, dated August QQlnVeDfiiOtl consistsin the novel constructiofi? and combination of parts hereinafter panying drawings, showing Figure 1 isadiagrammatical view of a burglar-alarm system embodying my p resent improvements; Fig. 2 isa similar view showing the same used in connection with the firealarnr system covered by the Letters Patent 3 is a detail viewof a flash-lightattachmcntadapted to be used in connection with the camera.

;-Referring to said figures by numerals of reference, 1, 2,3,and4 each designates a group said groups adapted upon one floor of the house in which the alarm is used and similar groups 5, 6, 7, and 8 may bearranged upon the second floor of said house. These circuitclosers maybe of various forms. Those shown close upon the opening ofdoors or 'windows of the house,

the rooms and adapted to close when a weight is placed thereon. I do not claim. any particular form of circuit-closer, as any suitable construction may be employed. Buttons, as iand 8, may be suitably arranged within the circuits, whereby said circuits may be closed by hand when desired. I

It will be understood that the circuit-closers 1, 2, 3, audit-are arranged uponacircuit which is independent of the circuit having the closers 5, (3, 7, and 8.

In each of these circuits.

is included an cleetromagnet 9, as will be plain by an examination of Figs. 1 and 2 of the drawings. These circuits are normally open, and therefore the armatures 10 are normally removed from their respective magnets 9, being preferably held in retracted position by means of coil-springs 11, as shown. The magnets 9 may be arranged at any desired point relative to the circuit-closers, and are all preferably arranged in close proximity to each other in the room or inclosurc wherein is situated a graphophone or phonograph signal device of suitable construction, such as will.

be more fully hereinafter described. This device consists of a series ofcylinders 12, mounted upon a common shaft 13, provided with a gear-pinion 14, which meshes with a gear 15, mounted on a driving-shaft 16, to which is connected a suitable motor, as 17. This motor may be of any desired form. I prefer to drive the phonograph-cylinders intcrmittently or only when an alarm issentin, and therefore provide a stop or like device which will be hereinafter described. Each cylinder bears a ple, the location of the building to which the system is applied and in addition the particular portion of that building wherein are located the circuit-closers ofthat particular local circuit which controls the'position of the transmitter or reproducer 18,a dapted to transmitthat record.

The reproducers 18 are each mounted'upon a tube or conduit 19, preferably in the manner shown and described in the patent hereinbefore mentioned, and said tube 19 extends from points adjacent to the cylinders 12 to an ordinary telephone-transmitter 20, which is arranged in an electrical circuit, such as will suitable rccord-for exam- IOO ,circuit, which, as it is, the means for assisting the transmission of signals produced by the 23 ee5,so1

scribed. A second wire 2-3, extending from the magnet 23, is secured to a stud 26, suitably mounted at a' oint adjacent to the armature 10 and adapted to contact therewith when the same is out of contact'with its magnet 9. A second stud 27 is mounted adjacent to the .armature22 of the magnet 23'and is connected to a wire 28, having a suitable battery, as 29, thereon The wire 24 is connected by means of a wire to the magnet 9 of the second circuit, as shown, and a wire 31, having-a battery, as 32, thereon, is connected by means of the wires 33 and 3% to the armatu res 10 of the magnets 54. It will be seen that each of the magnets 23 is connected to the wire 30. i 35 designates an electromagnet which is arranged. in a circuit including the battery 29 and wires 28 and 36. 'lhe'wire 36 01: this breaking of either of the hereinbefore-de- -scribed local circuits,- may be termed the common circuit, isconnected with the ar-' matures22 of the local-circnit magnets 23, andth'e other wire 28 is connected with the series of contact-points 2'7, hereinbefore described, said points beingarranged adjacent to and in the path of each-of the said armatures 22. The armature 3'? of the clcctromagnet 35 is pivotally supported and normallyheld in engagement with the lever-arm 38 by means of a spring-39. This lever-arm 38 is pivotally mounted at one end, as shown, its opposite end l0 .normally bearing upon the upper end of t-hearmature 37, as shown. This lever-arm 38 is secured to a wire 41 of an electric circuit connected to the transmitter 20, which includes also a magneto-generator 42, and is adapted, as will be hereinafter described, to be connected with the regular line of circuit connecting the telephone 3 with the central or exchange oiliee.

To the shaft 4- of the generator is geared a suitable motor 45, and a brake or step device 46 is-provided for normally preventing rotation of said shaft; This stop device preferably consists of a lever pivotally' mounted upon a bracket, as 47, one arm of which is adapted to engage with a toothed 'wheel 48 upon the shaft 44, while the otherarm is connected bymeans of a cord or other flexible device 49 to the lever-arm 38, hereinbefore described. arm of a lever 50, mounted upon a bracket 51 and adapted to act as a stop for holding the power-shaft 16 .of the graphophone signal apparatus stationary. Contactfpoints, as 52 and 53, are arranged below the leverarm 38 at the terminus of the wires 54 and This cord isalso connected to one 55, respectively, that are connected with the wires 56 and 57, leading from the telephone 43.

BEST AVAZLABLE com A camera 58 of any suitable construction may be arranged atany desired point within each of the rooms of the house. This camera is preferably provided with a shutter 59 of substantially the form shown in Figs. 1 and 2 and pivoted at one end, as at 60, to the easing of the camera. This shutter is provided with an aperture 61, which is adapted to register with the lens-opening within the casing when the shutter is partially raised, saidlensopeningbeing so located as to be closed when the shutter reaches its upper or lower limits of travel. A suitable flexible connection, as 62, connects said shutter with the arm 38 and may be arranged in any suitable manner.

At a point adjacent toeach of the cameras. is seen red a bracket63,substantially as shown in Fig. 3, to which is pivotallymouuted a verticitl substantially bell-shaped plate 04, the

on er edgcof which is roughened, as alt-65,

and adapted to contact with the head of a' match 66 or other-suitabledevice, which will ignite from frictional contact therewith, and a suitable cartridge 67, containing flash-light material, is arranged adjacent to the match and adapted to be ignited thereby. A cord 68 or other ileXible device connects the plate (it with the lever-arm 38, hereinbefore described. I

Each of the local'cirenits of this apparatus may be provided with a circuitdweaker," as 69, whereby the operationof the apparatus may be prevented, as desired. T-hese circuitbreakers are prei'erabl y placed upon the wires which do not connect with the magnets 23, ll

which support the phonograph-reproducers. The magnets 23 are normally in circuit, the current passing from the battery through the wires 3t 25, armatures l0, and wire 3* back to the battery 32, as isobvious. It will therefore be seen that the armatures 22 are normally held in contact with their magnets Whenever either of the local circuits is closed by means of the circuit-closers l, 2, 3, l, 5, G,

7, and S, the current from the battery will energize the magnet- 9 of said circuit and attract the armature l0. This will, as is obvious, break the circuit at the point 26 and release the armature 22 of the magnet 23, causing the reproduccr to fall upon the cylinder 12 of the phonograph. At the same time the armature 22 will contactwith the stud 2'7 and form acircuitincluding the wires 28 and 3G and the battery 20, charging .the

magnet-35, which will'attract its armature 37, and thereby release the lever-arm 38, which, under the pull exerted by the spring 70, secured t-hereto,as shown,will be thrown against thetwo contact- points 52 and 53,.as is obvious. Such movementot the lever-arm 38 releases the shaft t; of the generator 42 and the action ofthe latter rings the call-bell of the telephone 43, which call being transmitted over the wires 56 and 57 notifies the operator at the tact-poiuts52 and 53 the-record on the par- Io and over the wires 54, 55,,66, and 57.

The operation of the local circuits of the burglar-alarm apparatus shown in said Fig. 2 is the same in every respect as that of the fire-alarm apparatus described. in the above-mentioned pat cut.

By the term graphophone or phonograph, I mean to include any of the various forms of apparatus for producing the human voice or other sounds which may be adapted for use in my improved system.
