UNITED STATES FRANK J. KELLY, F BROOKLYN, NEW YORK.

CAR INDICATOR.

Application led January T0 @ZZ whom t may concern:

, Be it known that I, FRANK J. KELLY, a

citizen of the United States, and a resident of Brooklyn, -in the county of Kings and State of New York, have invented certain new and useful Improvements in Car Indicators, of which the following is a specification. p Y

This invention has special reference to indicators forcars in trains where a number of them compose the train, and indicate to the passengers the next stop to be made."

One of the objects of the invention is to provide an indicator that will be placed at an intermediate portion of the car, and show on the opposite sides the next station,-

so that it can be read by passengers 1n anyV part of the car.

A further object of the invention isY to.

provide a device of this character where a number of them will operatel in unison and can be controlled by the operator in any one of the cars.

A further object of the invention is to provide a device of this character in which the reels carrying the web for vthe stations thereon can be readily Vremoved and another web substituted for a different route of the train.

In the accompanying drawing showing one embodiment of my invention, Figure 1 is a front. elevation.

Fig. 2 is a horizontal section of the line 2-2 on Fig. 1,

Fig. 3 is a liagram of the circuit for the ten car train Fig. 4 is a vertical section enlarged at one end ofthe indicator.

Fig. 5 is a cross section on the line .5-5 of the Fig. 4.

Fig. 6 is a cross section on the line 6-6 on Fig. 4.

Fig. 7 is a cross section on the line 7-7 of Fig. 4. i

Fig. 8 showsthe web i f Fig. 9 is a detail view of a spool hub.

The device comprises essentially an elongated frame 2 with the casings '3' and 4at4 c the ends.A These casings are identical and the description of one will explain 'ftheother. -The frame 2, Shown 1n section '111 26, 1925. Serial No. 4,802.

the samestations printed on opposite por-v tions of its two faces as indicated in Fig. 8.

Means are provided for drawing this web Y in opposite directions as desired through the open frame, wvhen the stations printed in sequence throughout are exposed at the opposite windows 7 and. 8. At each end of the frame I provide in the casings 3 and 4 mountings for the reel 12, onwhich web or band 9 is wound, and also provide means for rotating the reel, that will draw the web between

guide rollers

13, 13, winding on one spool that will draw it off from the other spool. lli/*lien one spool has become full, or the Vcar is reversed in direction the spool in the other compartment is actuated, that will reversev the 4movement of the web. As shown in Fig. 4 the casing 4 has frame plates 16 and 17 mounted therein, one of which carries an'electric motor 18 on brackets 19. The reel 12 has its shaft 20 supported by a stopbearing 21 carried by a cross bar 22. This is removably supported by the frame ring 17 by means of headed studs 23 on the ring that pass through openings 24 in the bar 22, which openings have a narrow extension to receive' the stem of the v stud, thatv will lock the bar 22 in this position when inserted, and turned a short distance. By thus removing the step bearinor the reel can be withdrawn and another regl substituted. The lower part of the casing 4 is closed by a cap 25 held by studs 26 on the frame 17 that engage the slottedv openings 27 from removably attaching these aps.

The shaft 28l of the motor carries the gear 29 that meshes with the gear 30 on bracket 19, vThe latter gear engagesl an mternal gear 31 mounted in a bearing 32 on the trame le and a shat't 33 ot the internal gear engages the spool hub 34 by lugs that enter slotted port-ions 36 in the hub. By this means when the reel 12 is moved upwardly it will cause engagement ot the reel with the internal gear. rIhe motor 18 will thus operate the reel 12 at a reduced speed. The trames 1G and 17 are connected by bars at suitable places to form a rigid structure and support the casing 4.

Suitable means are provided to connect the end of the web to the spool. The spool 19 carrying the reel web or band is inserted, and one endv is caused to pass through the trame 2, and this end ot' the web attached to the spool 12 in the other compartment 3 constructed identical with the compartment 4, combining the reel and motor and other parts identical with that described. This motor in the compartment 8 is now operated and will draw the web across to expose the .stations on its opposite sides at the oppositev windows, and the motor will be actuated intermediate to bring the next station at the window, and then the motor is stopped. At the end of the route the wel is simply reversed by actuating the motor connected with the unwound reel.

In Fig. 3 I show the circuit for controlling ten ot the devices as described, indicated by 18 and 18 at each ot' the cars. In each car is a pair ot switches 40 and 41't'or controlling these motors. It will be seen that each of the motors 18 are connected by a line 43 that passes back by wire 42 through each ot the cars, the. wire 42 extending through all of the cais is connected with a switch 40 in each car. The line 47 extends through the cars and in each connects with the switch 40 so that closing thel switch 40 in any car will connect the line 42 and 47. The line 43 connects with one pole of a source ot current at 44, the other pole ot which connects with the line 47, therefore, closing any switch 40 will cause the current to flow through all ot the motors 1S. The other motors 18 in each ot the cars are all connected by a line 48 that is joined to the line 46 running back through all cars. The line trom the negative terminal ot the current source connects with each ot the switches 41 that also connect with the line 46. The line 48 also connects with the positive pole at 44, so that closing the switches 41 in any of the cars will send the current cars;

through all of the motors 1S in the ten This will actuate the web in one d1- rection 1n each car. The operator will Ysimply close the switch and inspect th-e'in- -dicator in the car as the web advances, andY as soon asv the next station, or the one desired appears at the window, the switch is opened. ',"Thi's means that in all of the` cars the same' f-ad'vagnce of* the web* takest place .and they will synchronize, which will bring the same station to exposed position in each car. For operating the web in the opposite direction in each ot the ten cars the duplicate arrangement of switches 41, that will operate motors 18 in the same manner, and advance the web in the opposite .direction in each ot the ten cars.

It will be seen that to insert the reel, either tull'oi empty, the cap 25 is removed, and then the bottom holder 22 is turned and withdrawn with the empty reel 17 that may be therein, and the full reel inserted in one compartment and the empty reel in the other compartment, the holder on one or both sides is drawn upwardly and the end ot the web that is passed between guide rollers 13 from the reel as drawn through the middle casing, and its end attached to the reel in the other compartment, and the slide replaced. In operation the guard in any car simply closes the switch that may consist only of push button and the empty reel will rotate by its motor and draw the web through the casing at the windows. The guard simply holds the switch closed until the proper station appears and then he releases. And since the motors synchronize the same effect will take place in all cars, as when the reel is placed in the device the same station appears in each car. The operator can of course cause the web to travel for a. distance of any number oi stations, where certain stations are omitted.
