To on whom it may concern:

Be it known that I, Pc'rna J. Mame, 91th zen of the United States, residing at Pittsbur h, in the. county of Allegheny and State a of ennsylvania,.have invented certain new and useful Improvements in'Street or Station Indicators, of which the following 1s a s eciflcation. n

his invention comprehends certain new and useful improvements in that class of station indicators that are designed to be used in traction or steam cars for' the purpose of automatically displaying the names of the ditl'crent streets or sto the inven- 18. tion being designed to also display an advertisement at the same'time it displays the name of the next station or stree so that the passen rs will have their at catio'n directed to t e advertising matter. 80 The primary object of the present invention is an improved apparatus of th s character which will be entirely automatic in its action, positive, sure and otherwise eflicient in operation and which will be com- 88 posed ofcomparatively few and simple parts that may be easily manufactured, assembled, and adjusted when necessary, and which will not be'liable to get out of order. With this and other ob'ects in view, my 0 invention consists esscntia ly in a street or station indicator embodying a display web adapted to wind from and on revoluble spools said spools being intermittlngl ac-' tasted at the desired time and automat cally 85 and itively stopped after each actuation, by c ectrical devices the circuits of wh ch are automatically controlled. wind the invention also consists in certain constructions, arran 'ments and combinations of the 0 parts that shall hereinafter full describe, and then point out the novel eatures in the appended claims. V

For a.full understanding of the inven tion, reference is to be had 0 the following discriiption and accompanying drawings in w to z. y

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawin by the same reference characters. The isp ay web 1 which is adapted to contain the names of the streets stations or stops m succession, together with other display matter such as a vertising is mounted to wind from and on s ools 2 and 3 mounted in a casing A Wl'llCl may be of any desired construction and design, suitable for mclosing and holding the operating parts. As best illustrated in Fig. 7, the web 1, as it passes from one roll or spool to the other travels over lldfl rollers 4 toward and around a simi or guide roller o,'the caain bein so formed, preferabl as illustrate an ing. 2, that it will disp ay the diil'erent stops or stations and the advertising matter or the like at both sides of the attenuated lower portion of the casing simultaneously, as in my Letters Patent of the United States, 888,126. dated December 11, 1906. 6, 6, esignate the two shafts of the spools 3 and 2 rasJcectivcly. Each of these s iafts is journals in brackets or similar bearings secured in any desired way within the easing A, and each shaft is provided at one end with a. ratchet wheel 7 designed to be engaged by a driving pawl 8 pivotally connected to a, pawl carrying disk 9, and pressed into engagement with its orresponding ratchet by means of a s rin as best seen in Filg. 5.

T his retarding belt is .-ecurcd at one end as by a wed e 42 as indicated i in Fig. ti, to a stationary ug 42 ot' the casing. and passes over a midc roller -13 mounted in a bearing 44. be other end of the retarding belt is held under tension by means of an adjusting nttt 45.

In describing the practical operation of my itnproved ellt't't or station indicator. it will be asetuned that all of the working parts are stationary and. ready to begin working. The magnet 22') is energized, the magnetic circuit being normally closed. As the ear approaches a street crossing or statiott. the nmgnetic circuit is opened by an external device. either upon the true or trolley, and thi dc'energizts the magnet 29,

therebv allowing the shipper lever spring 31. to pull the clutch s )ool 22' into engagement with the motel shit t clutch member 24. At the same time, the clutch lever also closes the motor switch 32 Fig. 8) thereby closing tlte motor circuit and causing the tnotor to rotate. This rotation manifc=tly effects the driving of the shaft 20 and worm 19 which is fit-tened rigidly thereon and the worm tlt'it'es the worm wheel 17 which is fastened to the friction disk which in turn drives its belt wltcel 14 am] pawl carrying disk 9. As the pawl 8 of said disk engages its ratchet wheel 7. itwill drive the latter, and will also in turn drive the spool 3 through the iustrumentality of the shaft ti. Both spools are thus driven by the belt 10 and cetttinue to rotate until one of the slots or openings 33 in the displav web 1 is btought into rc' istry with'thc display web 35, at which time the magnetic circuit is completed through the lower guide roller 5 and lower roller contact member 80, the track or trolley switch already referred to having become closet] shortly after the motor started to rotate. The tape switclr't'h'i and lower roll contact switch 30 are embodied in the magnetic circuit which also includes the electretnagaet- 2!) by suitable wiring. i'lhe magnetic circuit being thereby completed when the cir'uit; is closed between the points 34, 35 and 36, the magnet- 29 becomes energized. thereby throwm the spools 22, 22" from the motor clutch 2 into engagement with the stationar clutch member 23, atlecting a positive bra in action on the. shaft and causing the ca and the other parts to cotuc at once to a standstill, whileat the same time the bell crank lever 20, 27 is rocked in a direction to move its switch arm to the. leftin Fig. 8, thereby opening the motor switch 32. This brings tile mechanism to a full stop and completes V l the cycle of operation.

if the dis lay web is to be wound from the left halal spool to the right lnmd spool, the operations are the same except that the belt wheel on the right hand side is driven by the belt wheel on the other spool, through the driving belt 10. If the web is wound from the left lumd spool upon the right hand spool, the mtul of the ratchet: wheel on the left lnmd side will click over the wheel until the amount of display web on the right luuul spool exceeds that on the left hand spool. whereupon the pawl and the ratchet become locked, and the ditl'erence in speed bet worn the two spools is taken care 0 by the friction parts, the proper tension being obtained by means of the adjusting nuts 18.

In the preferred construction of the device the worm shaft 20 and motor shaft 20" are two separate or distinct parts. The clutch consisting of the spools 22 and 22' drives the worm shaft 20 by means of afeather or key working in a groove in the shaft, and said clutch is riven by means of the motor clutch 24. The motor has no way of driving the worm shaft c'xee t by means of this clutch. The object 0 this is to allow the motor to die down gradually after the current has been shut otl', while the clutch 22 and 22' and all mechanism driven by it is brought to a sudden stop by means of the stationary clutch member 23.

For the details of construction of the motor switch reference is to be had to Figs. 9 and 10. In these viewa a designates a ma to switch block; L a fiber hunger for the swi ch bar 1:: e the switch finger clamp; and (I the fiber insulation fol the switch bar. designotes the switch-operatin arm; 9 the phosphor bronze contact ngere; h contact screws, and i the connectors to the wire. k represents the shaft or axis upon which the switch bar turns, and l the phosphor bronze connecting arm of the contact fingers.

For a better upderstanding of the circuits by which the ditferent parts are operated, reference is to be particularly had to Fig. 11. 'lhe'trolley contact G coming in contact with the trolle trip' H causes the current to tlow throug the tri magnet E which raises the contacts F, t erebv opening the circuit in the magnet 29. The plunger or movable core of the magnet 29 thereupon moves downward, actuated by gravity and assisted by the spring 31 acting on the arms 30 and 30. The downward movement of the plunger closes the motor switch 32, and the motor circuit being closed, the motor shaft 2!? will revolve, and through the gears before described will wind the web or tape 1 from one spool over the contact .roller 5 and the contact wheel 34. Thereu on the circuit in the magnet will be close causing the core thereof to be moved up, and opening the motor circuit and thereby stopping the motor and bringing the machineto a standstill. The motor then remains stationary until the trolley contact. ti comes in conta t with the next trolley trip ll, when the above described operation is repeated. When the last opening 33 in the tape operates, the end being unwound is positioned between the contacts 3| and 3."), the. reverse switch ll is thrown to the opposite position, thereby rcvcrsing the direction of rotation of the motor shaft 21' and ausing the tape to be wound in the reverse direction. designates the junction or terminal blocks, 0 the snap snitch which cuts the apparatus ont'of circuit whenever desired. aml D represents a double pole fuse block with plug fuses.
