SIGNALING MECHANISM.

Application filed November 6, 1919. Serial No. 336,036.

To all whom it may concern:

Be it known that 1, Jesse C. SIMs, a citizen of the United States, and a resident of Maynard, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Signaling Mechanism, of which the following is a full, clear, and eX- act description. This invention relates to improvements in signaling mechanism, and more particularly to an electrically operated visual and sounding signal, an object of the invention being to provide improved signals which may be seen and heard both in the light and in the dark and which will be automatically operated.

A further object is to provide an im proved construction of signal casing with improved rotary signals therein and improved mechanism for operating the sigmechanism which is adapted for use as a railroad signal, as a fir'e or burglar alarm,

or for any other use to which such a mechanism might-be employed.

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more-fully the claims.

In the accompanying drawings Figure 1 is a view in elevation and partly diagrammatic illustrating my invention;

Figure 2 is a fragmentary view partly in elevation and partly in section illustrating the signal casing and the mechanism therein contained, the sectionbeing taken on the *line 22:of Figure 3; v

Figure -3 is a view-in horizontal section a through the casing;

Figure 4 is a view in section illustrating a form of contact which maybe utilized in connection with a burglar alarm; and

Figure 5 is a view-showing aform of contact which may be used on fire alarms.

' 1 represents a a circular signal casing which may be conveniently supported upon a post 2. The casing '1 is provided in its opposite sides with segmental transparent portions 3 and 4, theltransparent portions 3 being ina'. smaller arc than the trans-parent ortions 4, and the transparent portions 3 being of a color preferably red, while the transparent portions 4 are of plain glass or other similar material.

A platform 5 is provided in the casing 1 and a shaft 6 located centrally in the casing is supported in suitable bearing brackets 7. This shaft 6 at one end is secured to the center of a bar or spider 8, the latter carrying at its ends signaling segments 9 which are located between the transparent portions 4 and are readily observed therethrough. These segments 9 may be of metal or any other suitable material and are colored in various'ways as may be desired. 1 have illustrated the segments of two colors so that as they are moved around the casing and observed through the transparent portric lights move in an arc of a circle and serve to illuminate the. colored transparent portions 3 of the casing. The segments 9 are designed to attract attention in the daytime, and the lamps or lights 11 illuminating the transparent portions 3 will attract attention at night so that by turning the shaft 6 either in the day or in the night, the signal will be plainly seen.

An electric motor 12 is supported in the casing 1 and a drive shaft 13 of the motor is provided at its respective ends with

worms

14 and 15 respectively. The worm 14 transmits motion to a worm wheel 16 on shaft 6 and the worm 15 transmits motion to a shaft 18 which carries a rotary disk 19, the latter being provided in its face with blocks of insulation 20 for a purpose which will hereinafter appear.

The platform 5 also supports a horn or other electrically operated sounding device 21 and electro-magnets 22 are supported on the platform 5 and are adapted to attract an armature 26 which is connected to and insu lated from a series of

spring contacts

27, 28,

29 and 30, thelatter being suitably insulated from the platform 5. The

spring contacts

27, 28 and 29 are normally spaced from

stationary contacts

31, 32 and 33 respectively, while the spring contact 30 is normally located in engagement with a fixed contact 34.

A pair of brushes35 and 35 insulated from the platform 5 engages

contact discs

36 and 36 respectively, insulated from each other on the shaft 6, and these brushes and of the arms 10.

appear.

Electric lamps 38 are supported at the center and on the outside of both laces of the casing l. and are maintained illuminated normally.

When my improved signaling mechanism is used'in connection with a railroad, I pref- "erably utilize a rail 39 w-hiclris pressed downwardly by the weight of the train to engage contacts to close the circuit, and Thane illustrated a source of electricity ll which may constitute a part of the electric power system "of the railroad ,or'may be a separate source as maybe desired. In Figure 1, I illustrate a simpleform'ot electric diagram which permits the carrying out of my invention, but, of course, I do not wish to be limited to any'particular diagram.

'Alsn i'tch may be provided to open and close the circuits manually as may be desired. A. wire 43 connects one side of the battery 41 with the lamp 38 and from the lamp-a wire 44 extends to the contact 34. Thecontac'tt 34 is connected electrically with a wire 45 extending to the other side of the battery 41 so that while the

contacts

34 and 30 remain together, the circuitto the lamps 38 is closed. The wire 45 also connects to one terminal oi the magnets 22, the other terminal of the magnets being connected by a wire 46 with the rail 39. A wire 47 connects the contacts 40 with one side of the battery 41. Hence, when the rail .39 enthe contacts 420, the circuit through the magnets will be closed as follows: from the battery tl, through the wire 45. magnets 22, wire 46. rail 39, contacts 40, wire 47, to the battery. hen the magnets 22 areenergizechthe armature 26 and the spring con tact arms 27, QS'and 29 are moved into electric contact with the

contacts

31, 32 and 33 respectively.

The contacts 27. 28, and 29 are connected to the wire 45

wires

48, 49, and 50, re spe'ctiyely. Contact 33 is connected by a wire 51'to a la'Inp'61 which will be more particularly described hereinafter, the lamp 61' is connected by a wire to the brush 35, and the disc is connected to one of the? lainps 11 by wire The two lamps 11 are connected by a wire 52. and the second lamp 11, is connected "to the disc 36 by a wire 52*. The brush 35 contacting with the disc 36 is in electrical connection with the wire 5L3 by a wire 53. From the foregoing connections it 'will be seen that when the

contacts

29 and 33 engage each other, the lamps will be illuminated through the following" circuit: from battery 41, through wire 1,5, wire 50,

contacts

29 and 33, wire 51, lamp 61, wire 53, brush 35, disc 36, wire 52, lamp .11, wire 52"., other lamp 11, wire 52", disc 36, brush 35, wires 53 and 43, back to battery.

The contact 32, above referred to, is .connected by a wire 54 .with-one oi the brushes 37, the other-brush37 being connected bya wire with the horn21, and a zwirehfi c011- nects the other side of the horn with Wire 13. When the

contacts

28 and 32 are together, the circuit is from the battery.

through wire 45, wire 49, contacts "28 and 32, wire 54, one brush 37 ,disk l9,the,uthfl v brush 37 wire 55, 1101-1121, wire 56.,W1K64 to the battery.

The insulated portions 20 of the disk QID- ing into contact with the brushes 3.7 .cperat to open the circuit and hence, the ceases to blow for a time and then sounds again so that the operation 0i tilt/1 .111 13 an intermittent Ionemand may be 0QR1 10l19d as desired according to the length lofthe sulated portions on :the disk.

The contact 31 is connected by a wim 57 with .one side of motor 12a'nd a wire 38 connects the other side of the motor w th the Wire 56.' When the contacts 27121 1191311 are together, thezcircuit .is as fOllQWS t am ba tery 41, through wire 4:5, wire 18.,

contacts

27 and 31, wire .57, motor 12, wire :58, and wire -13 to the battery. the motor is thus included in circuit, it operates to give ,the circular motion to the segmented .and

the lam 11 causing the signaling das lay both in the light and in the dark,'as agove explained.

It will therefore be noted from the abov description that normally the QQ 133Ql'1S and 30. are together so that the lamps .38 will remain illuminated to illuminate the ou side ot the casing 1. When a. train presses the rail 39, the magnets 22 oause bh. ED81 tion of the contacts 34 andBO -.to1b1:eak the circuit and extihguishthe lamps 38. At the same time the

other contacts

27, 2 .5 M3512 are moved so as .to engage commie I31, 2

and 33, thus closingthe circuits t0. the lamp 11, horn 21 and motor 12. 1 The lamps 11 and the segments 9 are moved in a Qifcular path by means of the motor andthe horn is intermittently sounded so that attention is attracted to the signaling .deyice tofdudioate a warning.

As above stated, this signaling mechanism may be'utilized as a fire 'a1arm,o1:: 1% "hun'glar alarm, or for any. other purpose by t simple addition of obrious mechanism for controlling the circuits.

On top of the casing 11 may locate a.

transparent danger sign 60 and position the lamp 61 therein, which may be included in circuit with the lamps 11 as clearly shown in Figure 1 and as hereinbefore described.

The burglar alarm contact shown in Figure 4 may constitute a guard bar comprising two tubes 62 and 63 insulated from each other so that when a tool is forced through the outer tube against the inner tube, it will close the electric circuit.

The fire alarm contact employs a fusible string 64 covered by a shield 65 and holding a spring contact 66 open. The fire breaks the string and the circuit is closed.

My improved signal may be employed with any of these circuit closing devices and may be used on a closed or open circuit system as desired.

Various'slightchanges may be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
