and it is intended more particularly for theV display at proper predetermined times of street names, so that passengers u onv the car are apprised of the name of t e cross street toward which the caris moving. The same device, however, may be used for advertising purposes, or for both the display of street names and advertising matter..

The invention com rises a webfcontainin the matter to be Y isplayed, whether the names of streets or advertising matter, and

electrically propelled means made active at certain predetermined points are employed to move the web a sufficient distance to display the proper name or other matter.V

In accordance with the present invention means are provided for reversing the action of the electric propelling means so that when thecar makes ay return trip the street names may be displayed in the reverse order, so as v to coincide with the proper cross streets.

The indicator may be operated by any suitable means whereby the electric circuit is closed at predetermined intervals in order that the web may be actuated, but as such means forms no part of the present invention it is lunnecessary to either show or. describe them.

The invention will be fully` understood from the following detailed description, taken in connection with the accompanying drawings forming part of this specification, in which,- e I i ,Figure 1 is a face view, with parts broken away and in section and other parts in elevation, of the improved indicator Fig. 2 is an end view of the indicator,VV with the righthand end of the casing, as viewed in Fig. 1, removed, the casing being shownin section; Fig. 3 is a perspective view of a detail of the construction. v

Referring to the drawings, there is shown a casing 1 in the front of which there is a anel 2 of glass or other trans arent materia by which there is fed a we 3. containing the names of streets, or advertlslng matter, or

b'th. For convenience of description it be assumed that street names on y are to be displayed. This web is carried by two drums 4-'5, suitably journaled in the framework of the machine, the journals extending Vthrough one end ofthe casingjand being there provided with hand wheels 6 by means of which the drums may be manually operated. The other ends of the journals, shown at 7, stop short ofthe other end ofthe casing and have bearings in a plate 8 secured in the casing by stay rods 9. The front of the casing is somade that it is opa ue except where broken by the glass pangl 2, and, conseuently, the drums 4 5 and that ortion of t e web 3 wound thereon are hi den from view, and only the portion of the web opposite the glass panel is in sight. The casin and the parts contained thereby are mounte on the interior ofthe car in sight of the passengers. On each journal 7 beyond the supporting plate 8 there is secured a clutch member 10,k and mounted vloosely on the journal is another clutch member 11 arranged to engage the clutch member 10, and these clutch members are of they one-way type so that they will cause rotation of the drums in `one direction only.- It is toV be noted that the clutch 10-11V on one journal 7 is arranged to turn said journal in a direction opposite to the direction of rotation imarted tothe other journal by'its clutch.

ach clutch member 11 carries a gear wheel 12 and beyond this gear wheel the clutch member is provided witha hub 13 in which is formed an annular groove 14, and surrounding the journal 7 beyond the hub 13 is a helical spring 15 confined between the end ofthe hub and a plate 16 secured to the journal by a pin 17, Vor any other e uivalent means 4which may be used for ho ding the 'spring in place.

Extending, from the plate 8 near each vclutch is a bracket 1S having its end bifurcated and therevreceiving a lever 19. One end of this lever is forked, as shown at 20, and is provided with inwardly. projecting pins 21 engaging in the respective groove 14. The other ends of the levers 19 approach each other but terminate at points somewhat distant one from the other. At an intermediate point .there extends through the correspondlng end wall ofthe casing 1 a stud shaft 22 carrying exterior to the casing a crank handle 23, and interior to the casing this stud shaft carries a rock arm 24 projecting on opposite sides ofthe stud shaft and terminating at each end inV a segmental head 25.. These heads are formed on one face with cam enlargements 26, the said cam enlargements being on corresponding ends of the segmental heads 25. New, when the arm 24 is rocked by means of the shaft 22 one cam 26 will be moved into engagement with the corresponding lever 19, while the other cam enlargement will be moved out of the path of the other lever 19. The result is that one lever when engaged by a head 25 will be moved away from the corresponding end wall of the casing, while the other lever will be moved toward the corres ending end wall of the c asing since it, is aways under the Stress of the corresponding spring 115 and` when out of engagement with the correspond ing cam 26 it is free to move under the stress of that spring. The construction issuch that when a lever 19 is relieved from the action of its cam 26 the two members 10-11 ot' the corresponding clutch are brought into operative relation one to the other by the action of the spring 15, and when a lever 19 is moved by a cam head 25 thespring 15 is compressed and the two members of the clutch are uncou-pled. Furthermore, the arm 24 may be utilized as, al switch arm by coupling up the shaft 212 to one side of an electric circuitv and placing contact terminals27 on the inner face'y of the corresponding end of the casing in the path of the arm 24. These terminals may e so arranged as to be brought into contact with the arm 24 one at a time only, and then only when the members` of one clutch are in operative relation and they members of the other clutch are out of operative relation.

When the arm 24 isin an intermedia-te posi-` tion the cams 26 'are both in engagement with the levers 19, and, therefore, both clutches are out of operativey relation.

Fast on the plate 8 arey two solenoids 28, one in alinement with the other and each having an armature 29 fast to which is a rack-bar 30 suitably guided in a stud 31 on the plate 8, through which stud the rack-bar passes, and the other end of thev rack-bar is connected tol one end of a helical spring 32 the, other end of which is secured to a fixed stud 33 on a stationary part of the structure. The rack-bars are in mesh with the pinions 12 and these pinions are oi sufficient width to permit the movement of the clutch members carrying them to the extent necessary to be moved into and out of engagement with the other clutch members fast on the journals 7.

Secured to the plate 8 are two gongs 34, each in the path of a hammerhead 35 on the end ol a lever 36 pivoted in a bracket 37 on the plate 8 and engaged by a spring 38. rlhe ends ofthe levers36 remote, from the heads, 35 are in the: path of ins 39 fast on the ends of the rackbars, so t atl when the rack-bars are movedv by the energization of the solenoids the pins 39 will engage the levers 36 and move them against the action ol' the springs- 3S. Willen a pin 39 ultimately rides under the end of. a lever 36 the latter is released to the action of its spring 3S and strikes the gong a blow,A thus calling attention to the indica` tor.

When a solenoid 2S is energized and its armature or core 29 is moved into the solenoid the rack-bar causes the pinion 12 to rotate. It, now, the corresponding clutch members 10 and 11 are in operative relation the corresponding drum 4 or 5 will be rotated to a like extent and the web 3 will be wound thereon, at the same time unwinding l'rom the other drum. The extent oi' movement ol' the drums 4 and 5 is so regulated that a name displayed upon the web and visible through the panel 2 is moved out el' sight and the next succeeding name is moved into sight.

In order to prevent accidental movement o'l the drums 4 and 5 the heads oll each at one end are engaged by a spring 4() carried by a bracket 41 last on the corresponding end ot' the casing, and the tension ol' this spring` is adjustable by a thumb-screw 42.

We claim 1. A street car indicator comprising a web for containing appropriate legends, and. means for actuating said web at predetermined intervals comprising a drum l'or the web, a clutch member in iixed relation to the drum, another clutch member, means l'or moving the clutch members into and out ol o )erative relation, a pinion fast on the movable clutch member, a spring-controlled rack-bar meshing with said pinion, a solenoid connected to the rack-bar, and means l'or energizing said solenoid at predetermined intervals.

2. A street car indicator comprising a web for containing appropriate legends, two drums upon which said web is wound, a oneway clutch connected to one drum,another one-way clutch connected to the other drum and operating in the opposite sense to the iirst named drum, an electric actuating meansfor'cach drum, levers `for moving the clutches out of action, and means for moving the levers simultaneously or individually to carry the clutches to the inoperative position.
