Within thecasing directly below opening r is the weight 3, guided in its rising and falling movements-by vertical.

From one side of this weight a'rigid arm, T,

preferably rectangular in shape, extends across within the casing in such position that as the weight rises the arm will pass up close to-the faceof the wheel 0'. Sliding on the arm is the sleeve T, having pivoted in and extending longitudinally through its upper portion the rock-shaft if, having its ends turned at a right angle, so as to form armst t, projecting beyond the arm and sleeve, as shown best in, Fig. 5.

As the-pull on .the bell-ropeis continued,thecordU will then be pulled forward,'-swinging theitube R to the front, and so moving the slide T until the 'pawl arm 17, at its rear end,comes in line withv the teeth on the rear side of the wheel 0 above. Asthe cord Uis then pulled forward," it will bepulled out through the tube R, and theweight .S will be raised, carrying the arm' up with it, so that the pawl engages one of the teeth on wheel O,-and turns the latter to rotate 1 the 'band carrying rbllers to move the bands I 95 I. withlthenaines of thestations on, and also the; roller orjwheel L,-'a suflicient distance to bring opposite he openings EE' thenumber ing'iw i he t amesnnthe hands at this arrangement, as too i "as describedda 'gee ough to display .a .nuinbe'rof the names on the bandsf-I'flat a time, andas-at each stop the numbered. wheel is tu'ne'd to'display the ordinal of the "next;-s'tation', the passengers can at anytime n'ext'station isfbut can always see the names of several' -,stations ahead,- so that some time tbefo re the desired'station is. reached they can s'eeqits posit ion in the. order of stationsto be passed betore- 'reaching it; They can then telli'f aboutwhen to'prepare to get off, and can conseqnently-ibe' ready to: 'm'ove without delay when;'thestation: iswcached.

to the bell-rope.

When the bell-ropej ha's .been pulled 'to the.

front, as described, to operate theindieator, and is then let go,"the weight S,with its pawl sleeve-carrying arm, falls and draws back the cord, and'the weight u also falls to draw in the cord U and the ring thereon, andsotake upthe slack in cord U, as shown in full lines in Fig; 1. As the weight S falls, the pawlarm 15 onthe rock-shaft striking the teeth on wheel 0 swings freely upward until'it passes below the wheel, when the weight turns the rock-shaft to bring the pawl-arms horizontal again'.. When the trip is tobe made in the opposite direction, the clampV on cord U is unfastened from the bell-rope, and being carriedto the other side of the indicator, which side is now to be the front, is attached again A pull upon the bell-ropefrom that side will then cause the tube R to swing to lihaUSld6,.S0 as to slide the pawl-slide on the'weight-armto bring the other pawlarm into position to engage the teeth on the other side of wheel-O. and turn it in a direction opposite to that in which it was turned before. The bands I I and the numbered wheel will then be turned to indicatethe stations in proper order for the return-trip.

lnsteadiof having the swinging tube R, I

' .will then cause the pawl-slide to move in precontemplate, also, if desired, doing away with it, and having the cord U itself'engage the loop t on the pa'wlslide or anti-friction ul-l leys thereon, as shown in Fig. 8. The cord, as it. is pulled from one direction or the other,

cisely the same way as the tube. I prefer,

however, using the swinging tube, 'as described.

To lock the .lower band-roller, and so the upper roller and the numbered wheel from accidental turning, I provide the latch mechanism. (Shown bestin Figs. 3 and 6.) On

the end of the lower roller, toward the inner end of the casing; andjust within the partition 'G, I make a concentric series of notches, W. Through the partition/I make a vertical openw. In the upper end of such opening is in the forked metal bearing-piece W, fastened to the partitionif In the fork-arms w w of, this 1 piece are guide openings for the opposite ends of the sliding latch-blockNV", so situated that one of its ends preferably reduced in size, is adapted to engage the notches W orgtheroller when the block is slid toward the oller end. Up through an opening in this latch block or of the, stations on the straps; but I numbers.

bolt'passes the upper end of spring W tending to keep the latch-block normally pressed toward the roller to engage the notches thereon.

The lower end of the spring can be fastened in a block on the casing bottom or in the partition at the lower end of the opening w.

Piyoted' on a screw or stud, w, on 2; block, w ,-'onthe partition beside opening w, is the small weighted lever W, having'a pin, w,

normally resting against the side of spring W,

toward the roller end. :The o'ther end" of the.

and so forcing the spring W in the..same-.direction to remove the latch from engagement, with the notchin the roller j-ustgbefore the ,pawl on: the pawl-slide begins to engage and turn the wheel. Assoon, as 1ever""W* is re.- leased from the lug on the weight, the-spring. and latch fly back and the lever, because of its weighted end, returns to-fits normal position again.

, In the partition G, I.makea ;ilarge opening W ,in which can be placed,i-fdesired, a lamp to illuminate the indicator from within. The- .other partition has portions of its sides cut away, .as shown in Fig. 4, to allow light from In coupling my indicator to the bell-rope.

an amount of slack, preferably about sixfeet, .is' pulled to the rear end of the rear car. Thisis the usual amount of slack. The cord. from the indicator in each car is then connected, as

.IIO

The cord of each indicator is Y of such length and so connected with the bellrope that as the usual slack is-pulled forwardthe cord will be straightened out, and thenas the remainder of the slack, being the amount in excess of what is, usual, is'pulled;,forward* the cord will operate the indicator ihechanism in the manner set forth above.

Instead of numbers, of course other signs or marks could be usedto designate the names prefer the The amount of slackin-the bell-ropeand length of indicator-cord can of course'b'e varied, as desired, from the amount given above without departure from my invention.

The indicator-cord can be made any length, provided it is of'suflicient length from, the

indicator, .so that as. the conductor pulls an the slack out of the signal-rope in ringing of the indicator will slacken conductor cannot operate the rearward pull upon the bellthe bell the cord back, so that the indicator by his rope. g

Where, the trip isto-be a very long one, so

that more-stations will be passed than it willbe convenient to put numbers for on a num ber-wheelof moderate or convenient size, I

contemplate numbering the name of the station succeeding the one indicated by the highest number on the wheel No. 1,

- through the successive names. Thus the numbers on the wheel can be .15-

madeas the wheel rotates to indicate properly the stations on the band or strip, however long the list of names may be.

I have in the foregoing specification described the-indicator-cord as being attached to the bell-rope. Where the signal-rope, as on some roads, is not attached to .a bell, but to the whistle, so

thatthe-latter will be sounded whenthe conductor pulls the rope, the indicator-cord is to be attached to such ropevin the same-way, as it has been described as being connected with the bell-rope hereinbefore.
