To al?, whom t muy cof/wem: i I y f Be it `known that we7 elosnrn ALFRED lvERELL, Emmer Pinironnon, and Unire PLOURDE, all British subjects, `residing at Quebec city, fSte. Anne yde Beaupre, Ste. Anne de Beaupre7 respectively, all in Itho Province of Quebec, Dominion of Canada,

have invented certain newand useful inn provenients in ,automatic Street and @tation indicators; and we do hereby declare that the following is a full, clearg and exact de` vide a device of this character that maybe operated roin` anysuitahleplace'on the car, such as' inthe rear. where the conductor usually stands. 1` ,K

The invention will be readily understood from the accompanying drawings and following description,` in which like" numerals oi? reference indicatecorresponding parts in each ligure. In the drawings?? e e Figure l, is a front elevation oi the casing containing theldisplay sheet and operating mechanism.

1 the reversing handle.

Referring to the drawing;y l` indicates casing'containing two superposed horizontal shafts 8 which are journaled in suitable brackets mounted therein and carry drums y the upper E' will be ,positively driven, one `drum winding `by the bracl-ret ported..y

stepby step by means of a pawl-and-ratchety device (not shown) or `conwentional.type

which is enclosed in a `casing 1l loosely mounted on the end oishatt l() and in which an operating lever 1Q is fitted; Lthe arrangement being such that when said lever is swung in onedirection (ioreiainple, from itsy 'full-line position to its dotted-line position,

l? 3.), the pawleandfratchet device will `turn shaft lOfonc step in thesame direction.

This lmovement of Vvthe. shaft is transmitted through interineshing gears 9. and. Sto the 'lower vdrum shai't Enf onr which gear 8 is ymounted7 saidsha'ft 3? being provided withpa second gear -7 which is connected through an intermediate wear (j with a similar gear Ton in shaft, so that both drums 3 up and the other Adrinn unwinding the disi play sheet 2l." Thefinterinediate gear 6 is loosely mounted on a stub shaft v `carried The operating lever "l2 projects through a f slot 1B (F ig. 3) in the top wall of the'casing l and is provided adjacent its 'tree end with e a handle lll, vby means 'offwhichfit may be f directly shifted.

f to aetuate' said lever from a distance-'for 4instance from therearioi2 the car where the yconductor usually stands; and with thatend in view,` the lever isiornied with a perforated lug l5 (Fig 6) to which isconnected one end lt is ireierabie however. f

of an operating cord 16 orsimilar flexible element7 the other end or the cordbeing led l through an opening BO `iorined in Vaqcasing 27 (Fig. rloeatedin the rear part of the car. lThis casing 27, contains two pulleys 28` and 29 the latter of which is 'situated ad@` jacent opening 30; and the oord 16 is passed over said pulley, then under a pulley 34: at-

To facilitate the operation of lever 32, it may have suspended from it a handle 33., which projects downward through an opening in the bottom of casing 27 and a ldash-pot 35 may 4also he connected with said vlever to cushion its return movement when handle 253 isireleased.

" ln the construction illustrated,v the operating` lever 12 makes its active or driving' stroke whenmoving romlei't to rightfFig. 3) landy is returned to its 4initial position by means of aspring;` il which is secured thereto atene end and at the other end to the bottom Wall ef casing 1.; this spring 21 also serving to return the lever 32 tonormaL position, asavill he apparent. V:During the return movement of lever 12,'fthepaWl-andratchet device moves idly but it is to be understood that, ii' desired, said device may operate during 'the return` stroke instead et duringthe outward or initialstroke of the lever, or that suitable reversing means lmayhe employed in connection with the device 'to enable the Winding action to take place on the drum previouslyacting to unwind 'theV sheet. i However, itis sufficient vfor vall .present purposes that the operating lever acts as` previously described,V thev precise form ofratchet used not being material to the invention; In' any case, the `sheet Winds up :onone drum and unvvinds from the other, the Winding` drum heingprovided With suitahle compensating means, for exampleV a conventional slip clutch, inorder to take care of the increasing' diameter of one drumand the decreasing diameter of the other. The precise compensating 'means or device employed likewise v:terms no part of the actual invention and, hence, has not been indicated.

lt Will be obvious trom` the foregoing that atfeach operation oir fthelever 12, Whether ell'ected directly by means of' its handle 14,
