upon i meh ehe weh l0 is wound are represened lll and l2 and arranged prefeably I., one 'above Ahe other and shown, for example. in F10 3, @ne end of the web is attachedv o one of said drums and the other end ait-y taehed o'she other drum preferably by a,

pin-13 or its eouivalem; the arrangementhee5.` ing such that the web may be detached from the drums when iequii'ed. The web between ehe drums 'll end-12 passes 'around suitable guides le and l5 arranged. above and below' I the observation opening or panel 3.

Veni/ion', the shaft l@ of the lower drum 1Q ie mounted in hearings 17 in a bracket 21 f ion, :in the preferred embodiment of this in'. -f

retain the squared. end. of the shaft i3 in socket 19, the latch. being held in place by means of a spring 23 which permits the latch to be Withdrawn te admit of the removal of the shaft 18. 'The opposite ends of the shafts 16 and 18 are stepped in bearings at the opposite end of the casing A as shown in Figui In addition to the detachable feature of the shaft 18, the upper drum ll is journaled on its shaft 18 and is connected. thereto by means of a coiled spring Q5, one end of said spring being fastened to the shaft i8 at the point 26 and the other end of said spring' being fastened at the point 2'? to the drum 11,the arrangement being similar to ordinary spring curtain. shade roller, t lo ob'iect of this springty arrangement being to compensate for the wrappings of the web around the upper and lower drums to take up slack and prevent puclrering or buckling of the web in opera-tion.

The mechanism for operaties embodies a sprocket wheel stub shaft 20, from which a. sproclfet chain 29 extends downwardly around another sprocket Wheel 3Q :tast on the shaft 16, Fast on the same shaft 16 is a ratchet or notched wheel 31 adapted to be engaged and operated by either one of a pair of pawls 32 and 33 pivotally connected at 'and 35 to the lower arm 36 or" a tween-:ned lever which is journaled or ulcrumed pon the extended end portion oi,z the shaft The shorter arm 36 of said lever has pivotally connected thereto 37 a rod 38 to the opposite end of which is attached a contractile spring 39 having its outer end connected to a Xed bracket or lug 40 on the inside of the casing A as shown in Fig. 5, the tension of the spring 39 being utilized hold the lever in the position shown in Fig, 5. rlhe operating lever is moved in the opposite direction by means of a racl bar 4l which has a jointed connection at 42 with the' longer arm 36 of the operating lever, said rack bar 41 being in turn actuated by a pinion 43 against which the rack bar 4l is held by means of a backing roller 44., The pinion 43, as shown in Fig. 6 is mounted fast on a shaft 45 which extends through a bearing post 46 within the casing and has tast ,thereon an operating drum 4'? around which is wrapped an operating' cord or other lerible element 48, said cord extending outwardly through an opening 43 in a wall of the cas- 'ing A so that it may extend downwardly Within reach of the motor-man or conductor.

Each of the pawls 32 and 33 is held in operative position by means oi. a spring 50 as best shown in Fig. 7 and in order to hold one of said pawls inactive while the other is in operation, each ot said pawls is provided with a latch 51 which is shown terminait ing in a pin 52 movable along a slot hated generally at B in the longer arm. of the operating lever, the slot B comprising a longer branch 53 and a shorter branch 54. ltv will be understood by reference to Figi l that when either one of the pawls 32 is to he thrown out of operation, the pawl 32 is pressed downwardly until the pin 52 travels alongthe longer branch 53 of the slot enters the shorter branch 54. lhen left in this position, the pawl is held out oi operative relation to the ratchet or notched wheel 3l while the othervpawl remains in operation. This permits either of the )awls to be used according to the direction in which the inu dicating web is to be propelled. w

Betents 55 and 5G are arranged at opposite sides of the Wheel 31 and each of s d pawls is mounted on an' operatingv shaft 57 shown in Fig. 10, either o'said pawls 55 being adapted to be thrown into or out of' engagement with the notches or teeth of the wheel 3l according to the direction in which the webI is moving, by means a. suitable operating` handle or lever 58 at that end oit the shaft 57 which lies between the bracket 2l and the door l.

From the foregoing description, taken in connection with the accompanying; draw` ings, it will now be understood that the indicating web 10 which is exible, is wound .1, A upon the two drums ll and l2 and that the that intermittent motion is imparted to one of said drums by the pawl and ratchet elements also described hereinabove. lt will mther be understood that the web may he propelled in either direction by means ot' the operating lever contained within the casing', said lever being actuated in one direction by the pull cord or element 48 and being reu tracted or moved in the opposite direction by' the action of the spring 39. The door il gives access to the interior of the casing so as to admit et' the removal and replacement of the indicating web and the upper roller ll and also for the purpose of adjustn ing the reversing means consisting,f of the pawls 32 and 33 and the detents 55 and 56. rtherefore, a pull on the cord 48 will propel the indicating web in either direction according to the adjustment of said pawls and deteuts. The progressively increasing or decreasing distances between the street or station designations on the flexible web or ribbon l() insures the proper registration of the reading matter with and behind the observation panel 3 irrespective of the numkber ol windings of said web on either of lill ^ forth from either in the form, proportion and minor details of construction may be resorted to Without departing from the s irit or sacrificing any of the advantages o the invention.

`What I claim is 'In a station indicator, a plurality of drums having parallel axes, means for transmitting rotary motion from one drum s` other, anindicatin Web Wound upon said drums and adapte to be reeed back and one to the other, and means for manually revolving one of said drums including aV lever journale'd on the ft to Kthe shaft of the last named drum, a rack bar extending from said lever, a pinion for 0p- 15 eratirg said rack bar, pinion turning means,

a lever retracting element, and paWl and ratchet elements between said lever and last named drum. v
