The vmechanism is enclosed-in avease or boX,

indicated generally lat l and arranged toA be mounted in a conspicuous place at the `front end of the' vehicle so that the stopr or station designations displayed through the opening 27in the Jfront wall of the case or box, may" be easily seen by the passengersV inthe vehicle.

This box orca'se may be made of wood and i provided with 'a metal plate 3' upon the interio'r of each end wall lto supportthe mechanism.v

. Y Vficov The stop designations are printed or otherwisey impressed Vupon the *Y web `or band-4L,

` which' is' 'normally ro'lleduponV thev unwind-Y ing roll 5 and 'arranged to be unwound tromk Vsurfaces are rollers.

the roll 5'upon the winding roll 6, as the mechanism is operated, passing the web or .band intermittently across the opening 2 in the case..

Each of the rolls 5 and 6 is in the form ofv a spool provided with the enlarged periph- .eral flanges 7 at its ends and each of these Vr8 and 8 provided with friction vsurfaces of rubber or the like as shown at 9 and 9, between which the band is passed. v The rubber preferably vulcanizedv to the These frictiony propelling rollers are journaled at Yopposite ends in the end walls in the case, and the roll 8 is geared preferably at each end, by means ofthe pinions 10, with gears 11 fixed upon a rotating shaft 12 upon which isy also fixed a sprocket wheel 13 over. which an endless sprocket chain 14 is located.

The roller 8 is preferablyjournalled in a horizontal slot 8ft in the end walls of the case, and the-shaft 8isprovided with adjustable means for normally exerting aA desired pressure between the rolls 8 and 8 for propelling the band 4`Which passes upward from `the yunwinding roll 5 between Vthe propellingV rollers and then over idle rolls or shafts 11a located near the opening 2v and winding roll 6 upon which the band is wound as it is pro- .pelledv past the opening 2. l V35Y V'The means for adjusting the pressure between the rollers 8 and S" may include wedge slides 8b, provided with outwardly extending shafts 8c passing-through preferably vertically extending slots 8d in each end wall of the case, the shafts 8c being provided at their outer ends with knobs 8'?.l V

. Vhen the wedged slides 8b arein the posi- Vtion illustrated in Figs-2l and 3, pressure v,between the propelling-rolls is applied to y sprocketsY 15 and 16 which forthe purpose f enable propulsion of the band as aforesaid. When it ris ydesired to unwind the band formthe rolls 6 as hereafter to be described, the knobs 8b may be moved upwards, thereby relieving the pressure between the rollsS and 8. 'Y e v The sprocket chain 14, passesV over idle of convenience may be loosely journalled upon the shafts of the unwinding and windvingfrolls 5 and 6 respectively. l For the purpose of taking up slack in the sprocket chainanadjustably mounted pulley l.17 f may be provided, being arranged to be moved upon its support 17a fixed in adjusted. position to hold the chain taut as best shown f in Fig. 2.

The mechanism foroperating this sprocket chain to drive the propelling rollers comprisesa detent 18, pivotally mounted as at lower end, to a coil spring 26, the other end of which is connected to the slide, tending to urge the detent into the position' shown in dotted lines, in Fig. 2, against the stop pin 27upon the slide. l/Vhen held in the full line position, shown in Fig. 2, by means of the spring 24, the detent 18 engages the stop pin 28, in the adjacent end wall of the case, holding the extremity Aof Vthev d'letent laway fromthe path of the sprocket chain 14.

A cord 29 is fixed to the upper end of the slide 20 and passes over a pulley 30 being extended to any suitable position where it mayv be accessible to the motorman or conductor.

For the purpose of preventingl the belt from unwinding too rapidly from the lower or unwinding roll5 one or more curved tension springs 31 may engage the same as illus trated in Figs. 1 and 3; and for the purpose of winding the band upon the upper or winding roll 6, as it is propelled upward by the` friction propelling rollers 8 and 8, va helical spring 32 is provided.

This spring may be located within a casing 33 and operatively connected to the shaft 34 of the large sprocket wheel 35, a sprocket chain 35a being located around this wheel and around the smaller sprocket wheel 36 mounted upon the windingl roll 6.

VThis spring 32 is normally held under tension, as will be later described, 'and thus tendsl to'furgerthe sprocket wheel 35 in the direction of the arrow, shown in Fig. 3, thus winding the web or. band upon the winding roll 6 as it is propelled upward by means of the propelling krollers Sand 8.

kThe end of this web or bandmay be con'- nected to theroll 6 in the 'mannershown in Fig. 7, an aperture 37 being` provided in the kend portion of the band for engagement with a stud or pin 38 extended from the flat face y 39 of the roll.

TheV lower or unwinding roll 5 is preferably detachably vmounted, in its ournal bearings as shown in Figs. 5 and 6. This may be accomplished by` providing ya stud 40 in one end plate upon which is journaledl the sprocket wheel 15, normally urged 'outward upon the stud bythe spring 41. A hub 42 shaft of the upper or is provided upon this sprocket wheel vand receivesthe reduced lspindle 43 upon the adjacent end of the unwinding roll 5. A similar stud 44 is carried by theother end plate and the sleeve45 is journaled thereon and provided with a squared aperture46 to receive the squared'shank upon. the other Y end of the roll 5.

A pinion 48 is fixed upon thesleeve 4S5-and meshes with the gear 49 `mounted upon a shaft 50, j ournaled through the adjacent end wall, and provided with a crankl handle-51 by means of which the band or web may be rewound lupon the lower roll after the.V

vehicle has covered its route.- i v fis the band isthus rewound, 'the' spring 32.through the sprockets 35 `and*86.and sprocket chain a is rewound, beingfthus placed under tension ready for' lfurther operation. '-f

For the purpose of quickly/winding the band upon the upper or winding roll 6, `.in

.the event that the vehicle isfstopped. en

route, before it reaches its destination and is required'to return tothe starting point,

a handle crank 52 may be provided upon the shaft of theupper winding .roll.:6. .In order cover situation where a vehicle may travel two alternate branch routes, the

up to the hranch, after ,which two-or moreA band or web lmay have printed thereon asingle column of stop designations, asV indicated at 53, showing the stops upon the route parallel-columns, as indicated at lland 55, are provided showing the Vstops along each branch route. A shutter or door -56 is provided, upon thev front` face of the case, to'v cover each half of the Opening 2, thus providing means whereby one, column may be concealed when the vehicle is travelling overA the branch route shown: in the other column. chown in F 1g. 9., the car 1s travelling the branch route shown Von thecolumn OVC@ 5ft and the door or shutter' provided for the' other side of the `opening is in closed position, thus 'covering the stop designations in the column 55.

However, when the car is travelling over the main route, as shown in VF ig. 8, both of the shutters 'or doors are left Vin open position, thus displaying the stop designations upon the main route.

lt is the intention to provide uponV the band or web all ofthe stop designations throughout an entire round trip of the vehicle. Fig. 11 is a fragmentary view ofthe web and the designations nearfand at the end ofthe route illustrating the method of applying the designations in order to provide the band or web with all of the stop designat'ons throughout an entire round trip. As illustrated the route ends at street No. 132 which designation will be approximately in the middle of the band, the designations up to lflo. 132 being arranged 4on the band in prfifgressive sequenceand in regressive sequencebeyond the designation 182.

The vehicle thus starts from a central starting point and travels away therefrom to the extreme end of the route, and then returns back to the starting point during which they yindicating device requires.` no VattentionV exceptingthat the motorman orco-nductor pulls thecord 29 between stops.

with each 10u11 of. the @Ord-the Slide V2o is.4

movedupward into thedotted yline position, shown in Fig. 2, the'V spring 26 pulling vthe detent 18 into the dotted line yposition shownv in saidfligure,A into .engagement with the stop pin 2,7, engaging thedetentwith the sprocket Vchain I l-lfv and moving this chain a uniform distance with each operationwthev stoppin 57 limiting the upwardmovement of the slide. 1

In order to call 4attention to the operation of the indicator anxaudible signahisuch as the bell. 58, may be` provided, the spring pressed tapper 59 being'tripped bythe outerV i end of thedetent 18 to ring the bell with Veach upward operation of the slide.

ris the sprocket chain 14 :is moved a ,uni-rr the positively drivenfricti'on propelling: rollers 8 ward uniform. distance with leach operation. j

As the web or band is vino-ved upward with cada-operation ofthe cord the tension spring 32, acting upon the upper `or winding roll 6 will Yroll theweb tightlyupon sa'id upper roll while the tension springs 31,- engnging-'the lower or yunwindingroll will prevent thegsan'ieV froml unwinding too rap- `idly, thus holding the entire band; taut.

`As the pull upon the'cord is released, the coil spring 24 returns the slide to the initial posit-ion. shown in full lines in Fig. 2, in which. the detent is swung Yout of engagement with the chain and readyforanother operation. ,i

W'hen the carhas completed-a round trip, and returned-to .the lstarting point, the-en-y tire bandv is wound backwards upon the unwinding roll l5, by means vof the handle crank 51, and it will be seen that this winding operation will rotate the shaft 34: in a di- 8 move the weber band'fuprection to rewind the tension spring 32, thus each operation and means for automatically engaging the detent with the chain upon each operation of the slide.
