These levers are respectively. fulcrumed at 3,3 and 34 to a frame 35 depending from the car body, said frame being proranged bar 37 which is pivotally connected at 38 to the shorter ar`m321 lof the second named lever.

' The lower endof theba-r'37 `is provided Lwith a relatively large head 39 whichgis desirably equipped with a shoe 391 ofan elastic material. e l

Between said head vandthe guide 36 is provided a spring 40 to-yieldingly retainfthe bar 37'in its Vlowermost position which is limited by a `stop 371 o n` the bar encountering the guide v36. For raising the `'rod -26 for actuating lthe mechanism inthe casing to progressively move the web W, an elevating device is provided .along oneside of atrack rail, vas .42, inv proximity ofc-ach of the stations or stopping places whereasa` by another.

As illustrated 3, 4l and lvsaid elenameor legend onthe web is kto bel displaced j. vating device comprises a lever 43 provided in a housing 44 Vsecured to said rail.` n

This elevating lever is fulcruined to the housing '.44by means of a pin or bolt 45 and has a curved arm431, as shown in Fig. 3, to

, be engaged by and depressed by the iianges,

as147, of the car wheels 48 traveling upon the track rail 42, whereby the other arm 432 ofl the referred to lever will be swung upwardly toeifectthe elevationl of the bar 37 and rod '26 `for operating the apparatus. 49 repre- Lio - 3 with respect toA the; bar 37 sothat when v sents a spring acting to retainthe lever 4 3 in a position. clear of traflic;

the web 11 is shifted to `indicate the occur'- rences of the streets orstations.

This action occurs repeatedly 'duringv the krtravel of the car in a direction indicatedby l arrow inFig.

such means comprising a s0 lenoid.wiiiding; indicated by dotted lines 50 in Figs,-1 and'2 When the car is to vtravel in the opposite y lieu of the actuat-U ing mechanism illustrated .in Fig. elecf surrounding the rod 1'26 andincluded inyan" electric circuit,-.not shown,- which-isener-.-

l What we claim, is,-

1 In a railway car, thek combination with, `a web having street indicatingnames thereon, spools for .saidv web, shafts 'for .said spools, a reciprocatory rod, operat ive` con nections between said rod and the respective shafts and actuated bythealternate strokes of said rod forV turning the spools in opposite rotary directions, `and regulating 'de-y vices to render said connections temporarilyy inoperative with respect to' eitherpf said spools.selectively,of.means for effecting thev reciprocation of V-said rod, said means coin--` prising a frame secured to the car body and; provided with' av guideway, a vbar movabley axially in said guideway and arranged to,

normally support said rod, levers opera.-

. tively connecting said bar to the' rod, av lever: providedon the railway vtrack and arranged tox-be influenced by the car wheels whereby ido i said last named lever is influenced to cause said barto elevate therod throughtheinstrumentality of the-first named levers, and a spring to returnthe bar and rod to their y 2. In apparatus of the combinationofapair of spools, aweb having street lndicating names-. thereon,

shafts for said spools,wheels rigidly mountl i' ed on the respective shafts, rings mounted upon said wheels, said rings being provided in theiry inner peripheries with substantially triangular recesses, rollers provided in said recesses for rotatively coupling the ringsfto the associated wheels, cams., provided upon,

he character described,

the respective shafts, means for adjustably moving said cams ink unison whereby the rollers in one of said rings andthe rollers in the other ofthe rings are affected to render the rings operative to transmit rotary impulses to either of said Wheels Afor operating the spools selectively, and means for imparting rotary movements to both of said rings intermittently. l.

3. In apparatus of the character described, the combination with the Web, spools therefor, and shafts for said spools, of Wheels rigidly mounted on the respective shafts, rings mounted upon said Wheels, said rings 15 being provided With arm elements,lro1lers interposedy between the `complementary Wheels and rings for rotatively coupling thev same together, means for rendering ,j said i rollers inoperative to couple the rings 'to either .of said Wheels selectively, and means engageable with the arm elements ofws'aid" rings for imparting reciprocatory `rotary movements thereto. y y l.
