SPECIFICATION forming part of Letters Patent No. 388.371, dated August 21, 1888.

Application filed April 18,1888.

To aZZ whom, it may concern:

Be it known that LTnonas WILLIAM MUN- ROE, a subject of the Queen of Great Britain, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Autoinatic Station-Indicators for RailwayCars; and I do hereby declare that the following is a full, clear, and exact description of my said invention, reference being had to the drawings that accompany and form part of this specification.

My invention relates to devices for exhibiting in railway-cars, for theinformation of passengers, the names of streets or stations along the route in successive order and as they are approached in the run of the car.

The present improvements embrace certain novel construction and combination of auto matic mechanism that is set in motion by stops or fixed projections on the surface of the roadway, and operating, when set in motion, to display to view within the car and in successive order a series of cards or plates on which are arranged the names or matter for exhibition.

The cardoperating mechanism is also of novel construction in several points.

The nature of these improvements in station-indicators and the manner in which I have constructed and applied the same are fully explained and set forth in the following description, in which the accompanying drawings are referred to by figures and letters.

Referring to the said drawings, Figure l is a front view of the indicator-box, or that part of the device which is placed within the car, and contains the name-bearing cards for exhibition. A portion of the front of the box is broken away to expose the inside. Fig. 2 is a vertical transverse section taken through the line X X, Fig. 1, and showing also the upright rod and connecting-lever through which the automatic mechanism acts upon the card-elevator. Fig. 3 isa cross-section taken through the horizontal liney 1 Fig. 1. Figs. 4 and 5 represent in side elevation all the parts of the mechanism that are located under the indicator-box and beneath the car. Portions of the car-floor and frame-work at one end are shown in section. Fig. 6 is a side view, on a larger scale, of the gears and parts operated by them. Fig. 7 is an end view taken from the left-hand side of Fig. 6. Fig. 8 isa top Serial No. 271.082. (N0 model.)

] view of the mechanism, with the bed-plate broken away to expose the parts beneath. Figs. 9 and 10 show the clutch and the parts that throw it into and out of action.

Similarletters of reference indicatelike parts in all the figures of the drawings.

The indicator shown in Figs. 1, 2, and 3 of the drawings has the names of the stations and other matter to be exhibited for the information of passengers in the car arranged upon the separate cards or plates A A, that are set on edge in close order within the inclosingcase B and with their faces to the front.

Sight-openings BBare provided in the front of the ease, and the cards are elevated one at a time to view, the case being placed in some convenient part of the car where the openings will be in view of the passengers.

An indicator of this kind is seen in the Lotters Patent of the United States dated the 20th day of December, 1887, No. 375,326, that were issued to meas the inventor thereof; but, while being similar in character to that device, my present invention embraces points and features not found in that patent, and moreparticularly a construction and arrangement of mechanism by which each card after exhibition is turned completely over and deposited in such position in the case that when it is again elevated to view its opposite face is presented, whereby both faces of the card are utilized. This is effected by the following mechanism, which is acted upon by the automatic mechanism under the car. The sliding rod C is held in guides C, and, passing down from the case B to the bot tom of the car, is connected by a link, D, to one end of a bell-crank lever, D, the other end of which is attached to the endof ahorizontal puslrbar, E, suspended under the floor of the car. The bell-crank lever is pivoted at D in a bracket, D", that is fixed to the door of the car under the seat. To the upper end of the rod C is secured a forked frame that is formed of the back rod, G, forwardly-extending side arms, GG, and the inwardlybent ends GG", the arms being brought inside the case and to the front through the slots Zr I), so that the ends G lie in front of the foremost card at the sides and close to the face. These ends carry fingers G G that set against the face of the card and in line with slits or openings to a at the upper edge near the outer corners, and into these openings thefingers catch as the arms move upward in the case. At every upward stroke of the sliding rod the frame G, G, 850., which con stitutes the card-elevator, seizes a card in this manner and raises it from the bottom to the upper part of the case and then drops back into position, leaving the elevated card exposed to view upon the card-rest H.

Any portion of the reading matter on the foremost card in the bottom of the case can be shown and the rest concealed by having an opening of smaller area, B, in the case-front below the principal opening, and more or less of the matter can be displayed at this opening by regulating the size thereof to the dimension of the card. This is well illustrated in Fig. 1 of the drawings, where the matter on the lower portion of the foremost card at the bottom of the case is concealed, and only that at the top part is displayed. 1

The card-rest H is a horizontal bar fixed across the ease and at about the middle of the space, with small spring-tongues h h h, secured to the front of the bar. A movable rod, I, setting directly above the bar H and parallel with it, stands in position behind the card on the rest to hold it upright, and the springs K K, attached to the case-front, are set to hear at their free ends against the face of the card. This back rod I is movable vertically in the slots b and when this takes place the springs K come into play, and by their pressure act against the card to throw the top back with a quick motion toward the rear of the case as soon as the rod clears the card. The ends of the back rod are fixed in the slide-platesM M, and these parts are held and guided in the slots, in which they are movable vertically and together to throw up the rod, this movement being each time produced by engagement of the arms G with the lower ends of the slideplates M, and is made to take place when the elevating-frame starts upward with the card; but the rod is raised onlya sufficient distance by such movement to release the card, after which itis allowed to drop back by gravity, tlfat it may come into position to take behind and support the card being raised and as such card is left in position on the rest. To release the slide-plates and allow them to drop while the arms continue their upward motion, the inclined slots 1? P are formed in the slide-plates and thestop-pins l? P are fixed in the sides of the case-slots to take into the slots I, as seen in Fig. 1. In the upward movement of the plates, therefore, these slots and pins act to draw them back into the case-slots clear of the arms G, and these arms will run up over the plates, which are then free to drop back and bring down with them the back rod, I. The plates M extend so far down the case that the upsetting of one card is effected before the succeeding one is elevated so much as to be in the way, and the plates M, with bar I, then get back into normal position before the succeeding card is elevated. In this manner by a short upward stroke of the slide-rod O the card-elevating mechanism is operated, and at each stroke the elevator raises the foremost card from the bottom of the case and sets it on the card-rest; but in so doing it releases the card already on the rest, and the springs K K then throw the card backward and also completely over, so that it drops into the bottom of the case on its top edge and comes into position ready for the next elevation in its turn. This brings its opposite face to the front. When the rod 0 completes its stroke, it drops down and remains at rest until theautomatic mechanism below is set in motion again, and in such position of rest the fingers of the elevator are in front of the foremost card of the set, again ready to seize it at the next upward movement.

The bar Nis fixed across the case and in front of the stack of cards, as shown in Fig. 2, to hold the stack upright, and the bottom of the case slopes tothe front.

The cards can be made of sheet metal, vulcanized rubber, celluloid, or other sheet material possessing suitable stiffness.

The rod 0 is carried down from the case B behind the interior wood-work. In the streetcars of the present day there is usually sufficient room to place the automatic mechanism under the seats, in which case suitable openings are cut through the ear-floor for the drivechain from the axle and for the setting-lever that engages the fixed stops on the surface of the roadway; but where it may be more convenient the parts now to be described may be placed under the car, as shown in the drawings, a suitable casing (not shown) beingfixed over them to exclude dust and protect the parts. Thisautomaticmechanismiscomposed of two parts: first, a continuously-rotating shaft, 1*, driven from one of the car axles by means of a chain, 2, and sprocket-wheels 3 4, and carrying on one end a disk, 5, with a crank-pin, 6, to which one end of a loose pitman-bar, 7, is coupled; and, secondly, a setting mechanism by which the free end of this pitmanbar is made to engage with the free end of a horizontallysuspended push-bar, E,

- that is attached by its other end to the bellcrank D. As often as the pitman-bar is connected to the pushbar it is moved backward. The pitman-bar plays over a roller, 8, and its shank is curved. Its free end therefore vibrates in a curved, instead of a straight, path. The shaft 1 is driven continuously by the train of gears 9 10 11 12 from the sprocket-- wheel 4, the gear 9 and this wheel being fixed together on the loose sleeve 13 on the rockshaft 14, and the gear 10 and pinion 11 being loosely mounted in like manner on the other rock-shaft 15, while the remaining gear is fast on the shaft 1*. The motion is geared down in this manner to reduce the speed, as the crank would run too rapidly if driven directly from the axle. The end of the pitman-bar playing over the roller, but clear of the hook E of the push-bar, is made to take into this hook by giving the push-bar a short vertical moveboth ends.

ment, and this is produced by the following setting mechanism: A tappet, 16, fast on the rock-shaft 14 and having two curved toes,sets directly under the free end of the pushbar, and by a partial rotation of the shaft one or the other of its toes is thrown up against the bar. This motion is produced by clutching the rock-shaft to a loosely-running gear, 17, that is driven by the pinion ll, the gear being on the loose portion of a two-part clutch, 18 19, of which the other portion slides on the rock-shaft, but is keyed to it. This clutch is thrown by the setting-lever Y, that is pivoted at 20 to some convenient part of the truck, and in such position that its lower end shall stand in line with and in close relation to the fixed stops Z on the surface of the roadway, the lever being connected at the upper end by a rod, 21, to the end of an arm,22, that is fixed on the second roekshaft and depends from it. A segment-plate, 23, fixed on this shaft and slotted to let the rock-shaft 14 play through it, is set to move in a vertical are, and has one side of its face beveled, as shown at 00 00, Fig. 10, from the center out to This beveled side sets against the collar on the back of the sliding part of the clutch, so that as the segmentplate is moved by turning the rock-shaft in one direction or the other the clutch is thrown, and the rockshaft is thereby locked to the eontinuously running gear 17. When the setting-leverY strikes and is turned by a stop, Z, it moves the rock-shaft and brings the segment-plate against the back of the clutch, the result of which is to produce partial rotation of the rock-shaft 14 and throw one of the toes of its tappet up against the push-bar. This brings the hook E into line with the end of the pitman-bar, and as the latter comes forward it engages and throws the push-bar. At the end of this movement the parts release themselves, as the pitman-bar is drawn away by the motion of its crank, and the push-bar then re turns to position, ready for the next stroke.

The counter-weight 24 on the rock-shaft of the tappet acts to bring the tappet back into position, and as the connections between the rockshaft and the setting-lever are all rigid the weight also restores the lever to position after passing over the obstruction. Coilsprings could also be applied for such purpose, and, where found necessary, one can'be applied to bring the push-bar into position more quickly than the weight of the parts will do. A coil-spring applied, as shown, to one arm of the bell-crank will insure more prompt return of the parts to position. The free end of the push-bar is suspended by a slotted link, 25, from a swinging carrier-bar, 26, that is in turn suspended under the car by links 27 27, so that the push-bar is free to swing backward and forward, and also in a vertical direction at the free end when struck by the tappet.

The means by which the clutch is thrown off after each time of action consist of a fixed incline, 28, on the bottom of the bed-plate, and

a stud, 29,0n the shifting part 19 of the clutch, as shown at Figs. 7 and 9 of the drawings. These parts are so set that the roller on this stud comes in contact with the fixed incline and acts to separate the clutch as soon in the revolution thereof as the tappet has properly lifted the push-bar.

Now, as thus constructed and applied for operation in the manner above described, it will be noticed that the fixed stops on the surface ofthe roadway do not act directly on the indicator-rod to set the cards, but that the push-bar is brought into play by a slow motion, and when set to the pit-man-bar is acted on by such part wit-hasmooth regular motion, and not quickly or abruptly. The setting-lever simply acts, therefore, to throw the lifting device into gear and the parts that are be ing continuously driven from the axle.

The manner of setting and connecting the mechanism will be readily understood from the drawings. The lever Y is mounted on some convenient part of the running-gear of the car where it will not be affected by the motion of the car-body on its springs, and the bedplate, carrying the setting mechanism, is secured to the under side of the ear in suitably close relation thereto. The drive-chain is carried from a sprocketwheel fast on the axle, and connection is properly made between the setting-lever and the rock-shaft that works the tappet. From the end of the car, or that point where the case containing the namebeariug cards is located, the push-bar is carried along under the ear to the point where the tappet is located. The bed-plate is suitably formed with bearings in hangers for the shafts, and holes for bolts to secure it to the floor of the car.

The mechanism can be covered by a casing, if found necessary to protect it from dust.

In the operation of the setting mechanism the same action results whether the settinglever is struck from one side or the other, so that the indicator operates at all times, in whichever direction the car travels, without calling for any attention or special adjustment to change it.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-
