STATION-INDICATOR.
Specification of Letters Patent.
Patented Mar. 2'7, 1917.
Application filed August 21, 1914. Serial No. 857,977.
To all whom it may concern:
Be it known that I, l-IAnoLn S. HALTON, a. subject of the King of England, residing at Ridgeway, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Station- Indioators; and I do'hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a station indicator.
An object of the invention is to provide an attachment for a car by means of which the station or streets may be indicated as the car approaches.
A further object of the invention is to provide mechanism under control of the motorman of the car for actuating the device.
A still further object of the invention is to provide means for automatically stopping the indicating card in such position as to be visible from within the car.
A still further object is to provide automatic means for rendering the device inoperative.
With these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as herein set forth and subsequently claimed.
Referring to the drawing:
Figure 1 is a partial view of the inside of a car, showing the indicating device in place.
Fig. 2 is a section on line 22 of Fig. 1.
Fig. 3 is a section taken at right angles to Fig. 2. I
Fig. 4 is a detail of the mechanism for alining the indicating cards.
Fig. 5 is a plan View thereof.
Fig. 6'is a detail showing the means forcontrolling the driving clutch.
Fig. 7 is a diagrammatic view, showing the electrical circuits.
Fig. 8 is a detail of the indicating card latch.
Referring to the drawing by reference characters wherein like parts are indicated by like characters throughout the several views My device comprises a rectangular casing 1 divided into two compartments 2 and 3.
The front of the casing is closed by a cover 4 in which is formed a slot 5 closed by a magnifying glass 6 and in the lower portion of this cover 4 is a hinged door 7, by means of which access may be had to the casing.
Adjacent the lower end of the casing in compartment 2 is a transversely extending hexagonal roller 8 loosely mounted on a shaft 9, one end of which is rotatably mounted in the side wall of the casing 1 and extends tl'irough the dividing wall 10. On the extending end of this shaft in the compartment 3 is loosely mounted a sprocket wheel 11 having fixed thereto a clutch member 12. The end of this projected end is mounted in a bearing 13. A beveled gear 14 is secured to the extended end of the shaft 9 and meshes with a beveled gear on a motor 16.
Slidably mounted on the said end of the shaft 9 between the first mentioned clutch member and the gear 14, but prevented from rotation by a key 17 is aclutch member 18 which is operatively connected to an armature 19 of a relay 20, by means of which armature the said clutch is thrown into operative position.
A chain 21 is mounted on the wheel 11 and extends over a wheel 22 on a shaft 23, which is mounted in the walls of the casing and extends parallel to the roller 8.
A pair of rollers 24 and 25 are mounted rotatably in the upper portion of the compartment 2 and in spaced relation. These rollers are of similar formation to the roller 8 and have secured thereto gear wheels 26 which mesh with a gearwheel 27 on the shaft 23 in the compartment 2.
A pair of endless belts 28 pass around the roller 8 up over the roller 24 and thence downwardly under an additional roller 29 and again upwardly over the roller 25 and downwardly to the roller 8. Each of these belts is adjacent one end of the rollers and has a plurality of spaced clips 30 secured to the outer face thereof. These clips are arranged to grip a series of indicating cards 31 so that when the rollers are rotated the belts will be rotated therewith and the indicating cards brought one after another into registration with the slot 5 in the casin 1.
Fach of these cards 31 has a name of a station or street marked thereon and any additional information that it is desirable to impart to the passengers in the car.
The operation of the device is as folilows 2- The motor by virtue of the engagement of the gear wheels 14 and 15 rotates the shaft 9 and with it the clutch member 18 so that when this clutch operates the motor is thrown into engagement with the clutch member 12, the wheel 11 is rotated and the chain 21 rotates the sprocket wheel 22 on the shaft 23. By virtue of the engagement be tween the gear 27 and the adjacent gears 26' on the rollers 24L and 25, the said rollers are rotated. This causes the endless belts carrying the indicating cards 31 to be driven around the rollers 8, 2 1-, 25 and 29 so that the said indicating cards pass in front of the glass covered slot 5.
In order that said cards may bestopped in alincment with the slot 5 and in order that they may be moved one after another into such position, I have provided the following mechanism:
On the outside of the chain 21 in alinement with each of the cards 31 is an angu- V lar metallic projection 32 having insulating material 33 on the under face thereof. L0- cated in the compartment 3 adjacent the upper end thereof is a relay 34: and to the armature 35 of this relay is pivotally secured a latch member 36, the movement of which member is limited by a pair of ears 37, a contact 38 insulated from the latch 36 is secured to the lower side thereof.
The relays 20 and 34 are placed in a circuit as follows The current passes over a source of supply 39 and through the relay 20 thence to the motor 16 and thence to the relay 34 and from this relay to a switch 10 within the reach of the motorman, the current is then applied by a wire leading from the switch 10 back to the source of supply 39.
When the switch 40 is closed the relay 20 is energized and the electric magnet 41 thereof causes the armature 19 to be drawn toward the same, by which movement the clutch member 18 is thrown into engagement with the clutch member 12 and thus the operating shaft 23 is rotated, since the motor 16 being in the circuit rotates the shaft 9 to which the aforementioned shaft is connected by the chain 21. Simultaneously with the movement of the armature 19 the armature is drawn inwardly toward the magnets 12 so that the latch 36 is swung beneath the adjacent member 32 and in contact with the insulation on the under face thereof. As the movement of the chain 21 continues the next lower projection 32 moves upwardly and engages with the contact 38, which through a connection 43 joins the main circuit, at 14, between the source of supply and the motor 16. This contacting relation between the projection 32 and the latch 36 short circuits the motor 16 and relay 20 so as to cut the same out and stop the positive propelling of the chain 21, this chain continues in its upward movement by virtue of its momentum for a short distance and this movement is allowed by virtue of the pivotal connection between the latch 36 and the armature 35 but stopped when the latch 36 engages the uppermost ear 37 after the momentum of the chain has been partially spent then as soon as the motorman throws out the switch 10 the relay 34: is deenergized. 'When the relay 20 is de'einergized the armature 19 of the relay 20 is moved about its pivot by a spring lt so as to disengage the clutch members 18 and 12. The deenergizing of the relay 3a releases the armature 35, the spring 15- moves the same about its pivot so as to move the latch 36 bodily out of the line of movement of the members at which time the said latch 36 drops down about its pivot and in such relation to the adjacent projections 36 that. when it is again thrown into the line of movement of the said projectionsit will be beneath the adjacent projection and contact with the insulation thereon. The device is then again ready to'be operat'edto indicate the next street.
It may be seen that to operate the device to indicate a street or station it is only necessary that the motorman press a button, which will cause the mechanism to be actuated so that the name of the street or sta-' tion will be shown beneath the glass 6 in the slot 5, and when the button is released the device will again be in operative position so that the subsequent'opera tion of the button or switch 10 will cause the device to be actuated to indicate the next street. 7 a
From the foregoing description it may be seen that I have provided a device for indicating the name of a street or station which the car is approaching, and I have still further provided means within the control of the motorman for actuating the device,
and I have still further included in the de vice an electrical circuit such that when the controlling member within the reach of 119 the motorman is operated the name of the 7 street will be automatically shifted so as to be visible from the car casing.
\Vhile I have described a particular device it is obvious that numerous changes may be made within the structural details thereof without destroying the operation thereof and within the scope of the invention as defined by the claim.
lVhat is claimed is In a station. indicating device, the combination with a casing, of a pair of spaced rollers mounted therein, an endless chain of indicating cards passing over said rollers, sprockets operatively connected to said rollers and having an endless chain passing thereover, a plurality of projections'onsaid chain, a motor operatively connected to one of said rollers, an electric circuit in which the said motor is included, an electro-mag net having a pivoted armature, a latch member pivoted to said armature, a second circuit in which the said latch member and the projections on the chain are included, the said circuit being connected to the first mentioned circuit whereby When one of the sprockets on the chain engages the latch member the motor Will be short circuited and stopped and the latch member Will be 10 moved upwardly by the momentum of the chain, and means for engaging the said latch member to limit the upward movement thereof.
In testimony whereof, I affix my signature, in the presence of tWo Witnesses.
