STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 576,854, dated February 9, 1897. v Application filed September 24,1896. Serial No. 606,823. (No model ping-place, the indicator mechanism being positively operated by a motor controlled by an electric circuit and an apron or ribbon upon which the names of the stations are indicated, the operation being such that by closing the circuit the motor is released and moves the apron or ribbon to bring into view the name of the next station, and the motor is then automatically stopped, holding the apron stationary until it is again released by closing the circuit.

Our invention consists in the features and in the construction, arrangement, or combina-` tion of parts hereinafter described, and detinitely pointed out in the claims following the description, reference being had to the accompanying drawings, forming a part of this specification, wherein` Figure 1 is a perspective view of one of our improved indicators as it appears in actual use. Fig. 2 is a diagrammatic View illustrating the manner of connecting up in series a number of indicators throughout a railwaytrain. Fig. 3 is an end elevation of the spring-motor and its controlling-magnet and armature, the bell and the end of the casing being removed. Fig. 4 is a sectional view taken on the line 4 4 of Fig. 5. Fig. 5 is a horizontal sectional view. Fig. 6 is a vertical sectional view illust-rating the means for automatically stopping the motor, and Fig. 7 is a detail perspective view of the same.

Referring to the drawings, the numeral 1 indicates the casing containing the indicator mechanism, the hinged front 2 of which is provided With an aperture in which is inserted a pane of glass 3, through which the indicator-apron may be viewed. The casing 1 is also preferably provided with a hinged end 4 to afford access to the motor when it becomes necessary to wind up the latter. The casing is provided with a vertical transverse partition 5, and in said partition and the end 6 of the casing are journaled two drums 7and 8. The shafts 9 and 10 of said drums extend through the partition 5 and are respectively provided with pinions l1 and 12 of equal size. The drums are arranged one above the other, as shown in Fig. 6, and have wound upon them an apron or ribbon 13, upon which arer printed or marked the names of the stations in their proper order, and Which are adapted to be successively exposed to view through the window 3.

The mechanism for actuating the drums is constructed as follows: The numeral l4.in dicates a plate forming a support for the motor and its controlling-magnet and armature. Said plate is pivoted at one side to the partition 5 by a bolt 15, which passes through a sleeve or bushing 1G, attached to the plate, that serves to hold the plate a slight distance away from but parallel to the partition 5.

Attached to the plate 14 is a spring-motor 17 of ordinary and well-known construction, being merely a spring-driven train of gearing similar to a clock-movement. Upon the shaft 18 of the spring-motor is fixed a gear-wheel 10, that is adapted to gear with the pinion 12 on the shaft of the drum 8 when the plate 14 is in one posit-ion and also gears with a pinion 20, journaled on said plate 14, and the pinion 20, when the plate 14 is in its elevated position, gears with the pinion 11 on the shaft of the drum 7, as will more ful-ly hereinafter be explained.

The spring-motor actuates two ratchetwheels 21 and 22, the teeth of said ratchetwheels being arranged in opposite directions, as shown. An electromagnet 23 is fixed on the plate 14 and controls an armature 24, that is pivoted in bearings 25 on the plate and is provided with a detent 26, that is adapted to engage the teeth of the ratchetwheel 21, and thus arrest the movement of the spring-motor. A bell 27 is iixed on the shaft 1S, and a bell-hammer 2S is iixed on one end of an arm 29, that is pivoted at 30 to the plate of the motor-drum, the otherend of IOO said arm engaging the teeth of the ratchetwheel 22, whereby, when said ratchet-wheel is rotated, the arm is vibrated and the bellhammer thus caused to strike the bell and sound the alarm. The electromagnet 23 is included in an electric circuit, which also includes a battery or other suitable source of electricity and a push-button or circuitcloser of any preferred construction, whereby the magnet is caused to attract the arm aturc 24:, when the circuit is closed, and release the spring-motor, as will be 'hereinafter more fully described.

The plate 14, carrying the motor and its electric controlling device, is pivoted at one side in the manner before described and is provided with two arc-shaped slots 31,through which pass guide screws or bolts 32, that operate to hold the plate in parallelism with the partition 5. In order to maintain the plate 14 in its adjusted position, we provide a bolt 33, that is fitted to move longitudinally in a sleeve 34, fixed in the side of the plate opposite to the pivot 15 and which is adapted to engage any one of three perforations formed in a socket-plate 35, attached to the partition 5, said perforations being respectively numbered 3G, 3T, and 3S. A coiled spring 39 is arranged in the sleeve St and encircles the bolt 33 and at one end bears against a collar 10, formed on said bolt. Said spring operates to force the bolt into engagement with the perforations 3G, 37, and 38. Upon the shaft 13 of the spring-motor is fixed a handle 41, by means of which the shaft may be rotated to wind up the spring that actuates the motor. The apron 13, upon which the names of the stations are indicated, is provided along one edge with a series of perforations ht2, there being one such perforation for each station indicated.

Attached to the partition 5 and projecting into the path of travelof the apron 13 is an arm 43, which is longitudinally slotted, as at L14, to permit of the passage of the edge of the apron therethrough. The arm 43 is transversely perforated, (see Fig. 7,) and in such perforation is arranged a push-pin 45, that bears against thc apron 13 and is adapted to successively project through the perforations 42 in the latter. The other end of the pushpin 45 is flat and hinged to the lever 47, which is recessed at the other end, as at 48, and pivoted at 5f) to the elbowed post 5S. rlhe recess 48 isengaged by the end of an arm L1f), fixed on the armature 2l. A contractile spring 50 is attached at one end to said push-pin 45 and at its opposite end is attached to the arm 43. The spring 50 operates to draw the push-pin 45 in the proper direction to maintain it in contact with the apron 13 and to cause the same to protrude through the perforations 42 as the latter come opposite the end of the push-pin.l lVhen the push-pin is projected through any one of said perforations, the armature is moved away from its magnet and the detent 26 forced into engagement with one of the teeth of the ratchet-wheel 21, and the movement of the spring-motor is thus arrested.

In Fig. 2 we have shown in dia-gram the manner in which the indicators are connected in a railway-train. In such case there will be one or more indicators arranged in each car, and all the indicators will be connected in multiple are in an electric circuit, (indicated by the numeral 51,) which is energized by a battery 52 or other suitable source of electricity. A push-button 53 or other suitable form of circuit-closer yis arranged in the engine-cab or other suitable place and included in the circuit, whereby, when the circuit is closed, all the spring-motors will be sim ultaneously released and the indicators actuated in unison. In order to render the operation of coupling together the indicators automatic, we attach two conductors 54 and 55 to the under side of each car, and the terminals of said conductors are connected to the flexible ends 5G of the usual air-pipes, the extreme ends of the conductors being fixed to the metallic members of the hose-pipe couplings 57.

It will be manifest that when the hose-pipe couplings are jointed together in making up the train the indicators will at the same time be electrically connected in multiple arc.

The opera-tion of our improved indicators is as follows: Let it be assumed that the indicators are arranged throughout a railwaytrain and connected together in the manner shown in Fig. 2, and let it also be assumed that the train is about to depart from a station. The engineer then byrpushing the puslr button and thus closing the circuit attracts the armature of each indicator to its magnet and thus retraets the detent 26 from the ratchet-wheel 21 and thereby releases the spring-motor. The spring-motor when re leased operates to rotate one of the drums 7 or S and wind the apron thereon to bring into View the name of the station which the train is approaching. IVhen the name of the station is brought into View, its corresponding perforation 4-2 registers with the push-pin 15, and the latter is projected through said perforation by the spring 50, which movement, through the medium of the lever 17 and arm 19, moves the armature away from the magnet and causes the detent. 26 to engage the ratchet-wheel 21 and stop the motor, thus holding the indicator-apron stationary until the circuit is again closed. lVhile the motor is operating to actuate the apron, the bell is sounded by the mechanism heretofore described to attract the attention of the passengers to the name of the station being approached. l

In Fig. 4E we have shown the parts in proper position for rotating the drum 8, that is to say, the gear-wheel 19, driven by the motor, is in gear with the pinion 12 on the shaft of the drum 8. The pivoted plate 1st is then in its lowermost position, and is held fixed in such position by the bolt 33, resting in the IOO IIO

pertoration'SS.' \Vhen the train is traveling in the opposite direction, it is necessary to wind the apron about the drum 7, and this is accomplished by releasing the bolt 33 and raising the plate 14 on its pivot until the bolt 33 engages the perforation 3G, in which position the wheel 19 is out'of engagement with the pinion 12, While thepinion 20, driven by the wheel 19, is in engagement with the pinion 11 on the shaft of the drum 7, whereby said drum is rotated in the opposite direction to that in which the drum 8 was previously rotated.

By moving the plate 14. to positionintermediate the positions above referred to the bolt 33 engages the perforation 37, in which position the pinion 12 is out ofl engagement with the wheel 19, and the pinion is also out of engagement with the pinion 1l, and hence neither of the drums will be operated by the motor.

From the foregoing description it will be manifest that it is merely necessary to touch the push button to cause the indicators throughout the entire train to indicate the name of the station being approached, the indicators being automatically operated and stopped by the mechanism and in the manner described.

IVe have described the electric circuit as being energized by a battery, but it will be understood that on electrical railways the circuit may be fed from the line conductor that furnishes the energy for propelling the cars in a well-known manner.
