This invention relates to a novel and improved form of indicator, particularly of the type used in subway trains, street cars, and the like. The novel features will be best understood from the following description and the annexed drawings in which are shown certain selected embodiments of the invention and in which:

Fig. 1 is a face view of the indicator as seen, for example, from the outside of a car in which the indicator is installed.

The windows 5 and 6 not only expose the web to view butalso provide light for illumination. It is, of course, understood that this web is'opaque and has route designations on opposite sides thereof so arranged that the same designation is given simultaneously through both Windows 5 and 6. 1g. 3 is a view of the indicator as seen Supported in the casing as on shelves 8, is from the interior of acar with which it may a box 9 having an opening 10 in the bottom be used. i thereof through which may project a socket Fig. 4 is 11 adapted to receive an electric lamp 12.

Fig. 12 is a view of the novel form of web which may. be used with our indicator. F ig.- 13 is a wiring diagram showing how a plurality of indicators may be controlled to ether.

Tteferring first to Figs. 1 and 2, the indicator comprises a casing 1 which may be seecured in any desired manner in a car, the wall of which is indicated at 2. According to one feature of this invention, the route, is continually shown by one sign, here shown as a. web 3 mounted on rolls l'disposed on opposite sides ofwindows 5 and 6 in the lower part of the casing 1. The'window 5 a section on the line 4-4 of ings 13 and 14 and over idler rolls 21 in the upper corners of the box.

As best shown in Fig. 5, the web 18 carries terminal designations 22 and 23. The two designations 22 are the same, except that they are arranged in a pair with the two designations in the pair spaced longitudinally of the web and at such a distance that when one of 'thesedesignations is exposed through the opening 14 and the window 17, the other designation of the pair will be exposed throu h the openin 13 and window 16. The same holds true oft e designations indicated at 23. By this arrangement, it will be seen at right ansame modi neously from the same web at windows on the inside and outside .is disposed between these two designations so that it serves the purpose of illuminating both of them simultaneously, it being understood that the designations are translucent. By this we mean that the characters forming the designations may be translucent and their background opaque, or vice versa.

dle 7 throughgearin g, not shown, in t e usual that similar designations are exposed simultaof the car. The lamp 12 exposes the web to view on the outside of the .75 This web is carried upwardly past the open'-- 1 Supported on the box 9 is a second box 24 havin a closed bottom 25 resting upon the closed top 15 of the box 9. The top of the box 24 is provided with an opening 26 through which depends a lamp 27 secured in a socket 28 in the top of the casing. This lamp 27 is provided'with a neck 29 of such a length that the socket 28 need not extend into the box 24. By this arrangement the box 9 may be placed in the casing first, the opening 10 in its bottom receiving the socket 11. i

The web 18 has preferably adjacent each end thereof, a hand hole 18a (Fig. 5) through which the lamp 12 may now be inserted in the socket 11. In case a plurality of lamps are used, a. hand-hole may be provided for each lamp, or one hand-hole maybe used to insert several lamps, as desired.

After the box 9 is in place, the box 24 may be slid into position on top thereof, as indicated in Fig. 2. Then the lamp or lamps 27 may be placed in their respective sockets 28 by inserting them through one of the openings 30 or 31 in the-box 24 and through a handhole in the web 18, this web being provided with handholes similar to those just described above in connection with the web 18. Here, again, the number of lamps and handholes may be varied to suit various conditions.

It is, of course, understood that the vehicle on which the indicator is used will usually travel in opposite directions over a certain route. There may be different terminals for the vehicle in either direction of travel. For example, if the route is one running north and south, it may be that when the vehicle is traveling north over its route, there are several terminals, any one of which may be used as the end of its northbound trip. Similarly,

- of course, for its southbound trip, any one of a number of different terminals may be adopted. Therefore, we preferably place on one web 18, designations of all the terminals for the vehicle when traveling in one direction, and on the other web 18 we place designations of all the terminals for the vehicle when traveling in the opposite direction.

The casing has windows 32 and 33 registering with the openings 30 and 31 respectively, and the box 24 carries a web 18' corresponding to the web 18 in all essentials. In this box, however, the web is mounted on rolls 20 supported in the top of the box, and the web runs over idlers 21 in the bottom corners of the box. Otherwise, the arrangement is identical with what is used in the box 9.

Each web is operated by a handle 34, Figs. 3 and 6, through suitable gearing indicated generally by the numeral 35 in Figs. 6 and 7 The details of this gearing may be varied, as desired, and need not be further described. At the windows 16, 17 32 and 33, there is pzeferably shown the word to which may accompanied by an arrow, as shown in Figs. 1 and 3, for .the purpose of indicating to a passenger the terminal toward which the train or car is traveling. These designations may be permanently aflixed to the windows or may be placed on separate webs, as indicated at 35 in Fig. 6. The windows 16 and 32 .are mounted in a door 36 which maybe minal designation toward which the car istraveling, leaving the other terminal designation darkened by turning off the light which is provided for illuminating it. In this manner there is avoided the uncertainty and the loss of time involved in previous arrangements by which the trainmen were required to change each individual sign. Often such change is not made at all or is improperly made. lVith our invention, the two terminal designations and the route are properly displayed at the beginning of the day or other period of time during which the car is to be used on a certain route. Then, at the beginning of the first trip the lamp or lamps behind the designation of the terminal toward which the car is moving is lighted, and the lam behind the other terminal designations 1S turned off. At the end of the trip the illumination of the terminal designations is reversed. This operation'need not require the attention of individual trainmen but may be operated by the motorman in charge of an entire train. For example, Fig. 13 shows a wiring diagram in which are graphically indicated the webs 18 and 18 in a plurality of cars. In this diagram .one lamp is shown for each web, although in the other figures of the drawings two lamps are shown for each web, this obviously being a matter of design. The lamps 27 may be connected in parallel to a source of energy 40, and the lamps 12 may similarly be connected to the same source, and then all the lamps 27 and all the lamps 12 may be alternately illuminated by the operation of a two-way switch 41. This switch may conveniently be located at the motormans station, so that he may operate the lights on the entire train.

Referring now to Figs. 6, 7, 8 and 9, and particularly to Fig. 6, we have shown the rolls 20 as provided at their ends with shafts 42 received within bearings 43 which will be more fully described presently. These bearings are fixed on the wall of the box so that the axis of the roll shaft is alsofixed.

Each roll is provided adjacent its end with a disk 44 cooperating with a friction disk 45 having a hole through which the shaft 42 passes. A plate .46 carries and bears against both of the disks 45 which are disposed substantiall in a common plane, and any force exerted y the friction disk is governed by a spring 47, the tension of which maybe controlled by anadjusting screw 48. By this arrangement the tension on the web is maintained at a desired amount and, at the same time, the bearings for the roll shafts arefixed. It has been common in prior art constructions to have these hearings movable but, according 'to our invention, this is avoided, and at the same time an efficient tensiondevice is rovided.

eferring now more particularly to Figs. 8 and 9, it is seen that the bearings 43 comprise two parallel fixed members 49 which are here shown as loops in a one-piece metallic plate. These two fixed members form two opposite sides of the bearing, and the other two sides are formed by the legs 50 and 51 of a U-shaped bar. This bar passes through holes in the members 49 and the leg 51 is seen to be shorter than the leg 50, so that upon movement of the bar toward the left, as viewed in Figs. 8 and 9, the end of the leg 51 will move out of the way so that the shaft 42 may be removed. A spring 52 bearing between one of the members 49 and a head 53 of the leg 50 normally retains the bar in operative position to secure the shaft in place.

In Figs. 10 and 11 we have shown a medi fication of the arrangement for mounting the lamps to illuminate the webs l8 and 18. In this form the lamps 12 and 27 are mounted in sockets which are supported on aflexible member 54 which is hinged at 55adjacent one end of the casing between the boxes and latched at 55', the lamps and sockets projecting through openings therein. By this arran ement, each box 9 and 24' may be independently supported in the casing and the member 54 may be flexed one way or the other, as is necessary to getthe lamp sockets out of the way when the boxes are being inserted. V

In Fig. 12, we have shown a web 56 having terminal designations 57 r and .58 thereon arranged with respect to each other in the same way as indicated in Fig. 5. In this form, however, the sheet is white on the side which is exposed to the reader. The other side is coated with some substance which renders the web opaque, it being of course understood that 60 the web is made of the usual cloth which is portions of the translucent web itself and the background for the letters is formed by the relatively opaque coatin This coatin may be of any suitable material but we have ound that'an ink maybe formed of powderedaluminum and varnish, which will 'ivejthe desired results. This gives a background of the color of aluminum or silver and when there is no light behind the web the front or uncoated part appears substantially all white, although the letters may be discerned by a close inspection. Upon turning on of a lamp behind this web the letters or other characters standout prominently.
