lWithin a suitably constructed Acasing A are larranged two rollers B and C, on which winds and unwinds a Vweb D bearing the names E of the stations along the route over which the car is to travel in both directions.

The rollerV Bis located a distance above the roller Gand the web D is held stretched be'- tween the rollers. The roller B is the actuating rollerfor .winding up and unwinding the web D, as hereinafter more fully explained. The roller C is a spring-pressed roller of any approved construction, capable "of winding up. the web D; at the time the actuating roller B is turned in one direction -to unwind the web D, and the said spring roller @allowing the` web D to unwind at the time the actuating roller B is turned in the opposite direction to wind up the web D. During the unwinding of the web D from the spring roller C the spring thereof is placed under tension. The name E of an approaching 'station registers with a window A torniedvin` the front of the casing A so that the passengers in the car can read the `name of the next station.

In practice, two station indicators of like constructionare used, one at each end of the car, and operated simultaneously, as hereinafter more fully explained.

The actuating roller B is provided with a shaft B journaled in suitable bearings in the casing A, and on the left-hand end ofthe shaftB is secured a gear wheel B2 adapted to be engaged by a gear wheel F mounted to turn with and to slide on a driving shaft G Vjournaled in suitable bearings arranged in the casing A. The gear wheel B2 is also adapted to be engaged by a gear wheel F in mesh with a gear wheel F2 mounted to turn with and to slide on the driving shaft G in harmony with Vthe gear wheel F. The gear wheel F is ofsuihcient width to be in mesh atfthe same time with the gear wheel B2 and the gear wheel F2, as plainly indicated in Fig. l. When the driving shaft Gr is rotated in the direction of the arrow a. (see Fig. 8), andthe gear Awheel Fis out of. mesh with the gear wheel VB2 andthe gear wheel F is in mesh with the gear'wheel B2, then a rotary motion is given by the gear wheels F2, F and B2 to the roller sha-ft B t0 rotatethe CTI latter in the direction of the arrow b whereby the web D is wound up on the actuating roller B and unwound from the spring roller C. `When the gear wheels F, F, F2 are shifted from the left to the right into the position shown in Fig. 6 then the rotary motion of the shaft G in the direction of the arrow a is transmitted to the roller shaft B in the inverse direction of the arrow Z2 by the gear wheel F' being now 'in mesh withv the gear wheel B2 while the 'gear wheel .F is` Y out'of mesh with the gear wheel B2. l/Vhen this takes place the web D unw'iuds from the actuating roller B and is wound up by the spring roller C. y

In order to rotate the 'driving shaft G in the direction of the arrow a', the following arrangement is made: On the driving shaft G is mounted to rotate loosely a gear wheel H in mesh with a rack I mounted to slide transversely in the top -of the casing A (see Figs. l, 2, 3 and 5). The rack I is normally held 'inra forward position 'by the action of a spring I attached `at one ,end to the .casing and at the other ,end to the racl I, and to the rear end of the rack I is'secu-red a rope, cable or Iother connection I2 under the controljof the person in charge ofthe car to permitsuc'h person to slide the rack I rearwardly against the tension of the spring I with a view to rotate the gear wheel H in the direction of the arrow a. lVhen the person in charge of the car releases the pull on the connection ,I2 then the 'rack I returns to normal forward position by the 4action ofY the spring I. On .one face of the gear wheel H 1s secured anvarm H carrying a pawl H2 in engagement with the peripheral face of a ratchet wheel H3 having a single tooth H4 (see Fig. 7'). The ratchet Wheel Havis keyed or otherwise fastened to the shaft G,` and when the gear wheel HA is rotated on moving the rack I rearwardly in the direction of the arrow c (see Fig. 2) then the pawl H2 finally engages the tooth H4 and turns the ratchet wheel H3 in the direction ofthe arrow a thus rotating the shaftG 'in the same direction. The rack I is .of such length that during its full rearward movement a complete turn is given tov cured a locking wheel J provided with a peripheral notch J adapted to be engaged by a friction roller J2 journaled ,on a vertically-disposed rod J 3 mounted to Vslide verti' .so ythat 4the roller `J2 moves out of engage- J. ment of the rack I the arm J Gjmoves into Vengagement with the topv of the pin J 5 and cally in a suitable bearing A2 attached to theY top of thecasing A (see Fig. 2). The rod J 2 is pressed on by a spring J 2 to normally `hold the roller J2 in engagement with the notch J to prevent accidental turning of the shaft B. The rod J 2 is provided with a pin J 5 adapted to ,be engaged by an arm J 6 pivoted on the rack I and moving with theV same. llhen the rack I is in normal front position the free endof .the arni J s Aextends underthe pin J5 and `when the rack I is moved rearwardly in the direction of the arrow c, as previously explained, then the arm J G lifts the pin J 5 and with it the rod J 2 ment with the notch J .to unlock the locking wheel l at the time the pawl H2 has reached the tooth H4 (see p Fig. 3). Shortly` after the shaft G 'has begun to rotate the pivotal end of the arm J passes from under the pin J5 so that the friction roller J2 now` engages and travels on the peripheral face of the locking wheel J, and when-tithe shaft G `has made a `complete revolution'therod `J3 is pressed downward by its spring J2 toreengage the friction roller J2 withthe notch During the subsequent return move- 1s swung upward to allow the arm J 6 to 'ride on the pin J 5 n' until `the rack Ireaches its normal forward position and when this takes place the arm J 6 swings downward into position to rengage thennder side of theV pin J5 von lthe next rearward movement of the rack I.` Y l The driving and reversing gear consisting of the Vgear wheels F, F, F2 is automaticallyishifted from the roller shaft B and relatively to fthe gear wheel B2 of the 105 saidv roller shaft. V,For this purpose the following arrangement made: On therroller 'shaft B 1s secured a' gearwheel KV in mesh with a ,gear wheel K attached to aninter- Y mediate .shaft -K2 journaled in suitable 110 bearingsin the'casingA, and arranged par-` allel to the roller shaft B.` A gear wheel L havingV the flanges YL is mounted to turn with and to slide lengthwise on the shaft K2 by the use of a key K2 held on the shaft K2 115 land engaging va keywayV in the gear wheel L. 4The gear wheel L .is in mesh with a gear wheel N 4formed on the peripheral face of a nut N screwing on a traverse screw VO supported in the casing A. 'Ihe gear wheel 120 N extends 'between the flanges L of the `gear wheel L and when the shaft .K2 is driven from the shaft BY then the gear wheel L rotates the gear wheel N and indoing so causes the nut N to screw on the .125

traiferse screw 'O whereby .the Vgear Awheel L is carried along and sh-ifted'in the same l direction in which the nut is traveling at the time on `the traverse screw O. On the faces of the nut N are arranged lugs N2, N3 130 Lor-1,45*?

of which the lug N2 is adapted to engage an arm P while the lugNS is adapted to engage an arm P, the arms P and P being secured to a rock shaft P2 j ournaled in suit,-4

wheel nut N Vmovesto the left its lug N2 engages thel arm P at the-time the car A has reached the second last station on the route,

and when the operator actuates `the stationt `indicator. to display` the last station within,

the lug N2 imparts "a 'swinging motion to the arm P to rock the shaft P2 which byV the pin P3 imparts a swingingl motion to the shifting lever Q toshift'mthe gear-wheels F, F',F2 from the ,position shown in Fig. l into the position shown in Fig. 6,' wherebythel gear wheel F' moves out of mesh 7with the gear wheel B2 and` the `gear .wheel F moves inmesh with the gear wheel B2.

When the shaft G is next rotated on the operator manipulating the rack-I; as previ-` ously explained, then thel actuating roller shaft vB' is turned in the opposite direction to wind up the web D on the roller B, that A is, so as to display the stations E 4in the reverse order during `the return trip o-f the` car.V When the car reaches the .second last station on the return" trip theV gear wheel nut N has traveled to the right so that the lug N3 is in engagement with'the arm P',

and when the car-travels to the rst station and the oper'atorractuates the shaft G, as previously explained, then the lug N2' imparts a swingingmotion t0 lthe arm P to rock the shaft P2 in the reverse direction so thatthe pin P2 imparts a returnswinging `motion to the shifting lever Q to move the gear wheels F, F', F2`bacl to thevoriginal position shown in Fig. 1. When theshaft B is next turned, the web D `again unwinds from the rollerB and is wound up by the spring roller C during the next outgoing trip of the car. Y Y

VThe operation 1s as follows: When the several parts are in the position shown in Figs. l, 2 and 5, thecaris on l-the outgoing trip, and when the car leaves a station the operator in chargeof the car pulls the flexib le connection I2-to` cause the shaft G to be- Y come unlocked and to rotate, as previously explained, and a rotary motion is transmitted by the gearwheels F 2,YF andB2 to the'shaft B and lconsequently the roller B to wind up the web D on the said roller B.

The name E now in register with the window A' is that of the next station. The

`above operation is repeated for each station along the route, and when the second last station has been passed and the operator Vcauses the shaft G to rotate then the lever Q is actuated as above explained to shift the gear wheels F, F', F2 from the position shown in Figs. 1 and z5 to that shown in Fig. 6, whereby the next rotation given to the 'shaft Gr causes the shaft B' and the roller B to rotate in the reverse direction of the arrow b so that the web D unwinds from the roller B and winds up on the roller C, of the gearwheels F, F2. When the ygear From the foregoing it will be seen that during the return trip of the car the names of. the stations are displayed in the same manner as above described during the outgoing trip and no re-setting whatever of the mechanism by the operatorin charge 1s required. Should the car for any reason not travel the entire lengthofj its route and is compelled to return then the operator in charge `can actuate the shifting lever Q to provide a reverse movement of the actuating roller B. For the purpo-se mentioned the shifting lever Q is provided with a handle Q5 extending through a slot A3 in the bottom of the casing so that the handle Q5 is within reach of the operator.v Y Having thus described my invention, I claim as new and desire to secure by Letters Patent:
