STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 575,585, dated January 19, 1897'. Application iiled July 8, 1896. Serial No. 598,435. (No modell To @ZZ whom it' may concern.-

Be it known that I, WILLIAM M. BAKER, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Station-Indicators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in station-indicators, the object of the same being to provide a device for indicating the neXt stop which the train will make, located at a convenient part of the passenger-coach and to be automatically tripped into action.

The invention consists of a framework mounted in a suitable casing with an opening therein, the said casing being located at a convenient part of a passenger-car, a pair of drums or rollers mounted in said framework, a roll of paper or other suitable material containing the names Aof the stations upon its outer surface printed in order thereon and;

Wound upon said drums or rollers, springs for maintaining` the tension of said roll, means for automatically shifting said roll for exposing a different station through the opening in the casing, and means for reversing the direction in which said roll is wound upon said drums or rollers.

The invention also consists in other details of construction and combinations of parts which will be hereinafter more fully described and claimed.

In the drawings forming part of this speciiication, Figure l represents a front elevation of my device with the casing partly broken away to show the interior construction. Fig. 2 is a side elevation with the casing removed. Fig. 3 is a similar view of the opposite side. Fig. 4 is a vertical section through the same, taken parallel tothe sides of the framework. Fig. 5 is a longitudinal section through one of the drums or rollers and the shaft upon which it is mounted. Fig. 6 is a perspective view of the rail, showing means connected thereto for automatically tripping the device into operation. Fig. 7 isacross-section through the rail, showing the trip lug or projection thereon. Fig. 8 is a View showing a modified form of the invention. Fig. 9 is a similar view of the same, looking at right angles thereto.

Like reference-numerals indicate like parts in the different views.

The casing l of my device is located at any convenient part of a passen ger-car and has an opening 2 therein, through which the names of the different stations may be viewed one at a time. On the inside of the casing l is mounted a framework made up of two side plates 3 and it, which are suitably braced and supported by means of connecting-rods 5 and G at the rear thereof and similar connecting- rods 7 and 8 at the front. Extending through the upper ends of the plates 3 and et is a shaft 9, having a rectangular extension l0 upon one end and a drum or roller 1l loosely mounted thereon, which is connected to said shaft by means of a coil-spring l2, whereby the tension on said drum is maintained. Upon the outer end of the shaft 9is a ratchet-wheel 13, which is engaged by a spring-actuated pawl la for preventing the turning of said shaft to unwind the spring. The spring is wound up by inserting a key upon the rectangular extension l0 and turning said shaft. At a point near the lower end of the framework and mounted in the side plates 3 and d is a similar shaft l5, having a similar rectangular extension 16, and asimilar drum 17, mounted thereon and connected to said shaft in a similar manner.

Both of the drums or rollers ll and 17 have guide plates or flanges 18 1S upon their outer ends, and around said drums is wound a strip or roll 19 of paper or other suitable material, having the names of the different stations along the route of the railway printed in order upon the outer face thereof and adapted to be visible one at a time lthrough the opening 2 in the casing l. The said roll of paper 1f) passes over the connecting-rod 7 adjacent to the drum or roller ll and thence between two guide-rollers 20 2l, mounted in the front side of the framework in the side plates 3 4 thereof. The guide-roller 20 is an idle-roller, but the guide-roller 2l is mounted in slots 22 22 in the side pieces 3 t and has a pinion 23 upon one end thereof outside of the plate 3. Brackets 21 2l are secu red to the front edge of the side plates 3 and 4, respectively, and through these brackets project tightening-screws 25 25, whose inner ends are adapted to engage the pintles 2G upon the outer ends of the guideroller 21. By this means the guide-roller 21 may be forced into close engagement with the roll 2O and acts as a gripping-roll therefor. The pinion 23 upon the outer end of the roller 2l meshes with an idle-pinion 27, loosely mounted upon the side 3 of the framework, as clearly shown. Connecting the two side plates 3 and t of the framework at a point between the drums or rollers 11 and 17 is a shaft 28, to which is secured a spiral spring 29 upon the outer face of the plate 4, the said shaft being also provided with a rectangular extension 30 upon the end which projects through the side plate To this shaft is also keyed or otherwise secured a cog-wheel 31, which meshes with a pinion 32, mounted upon a shaft 33, which projects through and is slidingly mounted in a segmental slot 3f in the side plate Fulcrumed to the sha-ft 2S at a point between the side plate 3 and the cog-wheel 31 thereon is a lever 35, having a laterally-extending arm 3G, which is connected to the shaft 33, upon which the pinion 32 is mounted. By this construction it will be seen that by moving the outer end of the lever 35 up or down the sliding pinion 32 maybe thrown into mesh with either the pinion 23 upon the outer end of the roller 21 or with the idle-pinion 27. The rotation of the shaft 2S, therefore, in one direction would cause a rotation of the roller 21 in one direction or the other, according to whether the sliding pinion 32 is in engagement with the idle-pinion i7 or the pinion 23. Secured to the shaft 2S at a point adjacent to the inner surface of the side plate et is a ratchet-whel 37, with which an escapement pawl or lever 3S, pivoted to the side plate 4, is adapted to engage. The outer end of the escapcment pawl or lever 3S has a flanged arm 39 thereon, which is connected through the spring 4() with the connecting-rod G, as clearly shown. Pivoted to the side plate 4 is a triplever ll, which is adapted to engage the under side of the flanged arm 39 on said escapement-lever. The outer end of said trip-lever ll is connected through the spring 2 with the upper connecting-rod 5, thereby holding the inner end of said trip-lever out of engagement with said fianged arm. The outer end of said tri p-lever 4:1 is further connected through a pitman t3 with a bell-crank lever ett, fulcrumed to the under side of the car and having one arm extending down along the side of the rail 15, as clearly shown in Fig. (i. This arm is adapted to engage a lug or projection 1G upon the Aside of`the rail for the purpose of automatically operating to shift the roll or strip 19 the distance of the space between two of the stations printed on said roll.

The operation of my device is as follows: Then my improved indicator is first placed in the carin which it is to be used, the roll 19 is secured to the ends of the drums or rollers 11 and 17 and the shafts 9 and 15 turned by a suitable key applied to the rectangular extensions 1() and 1G on said shafts to tighten the springs therein to give the proper tension to the roll or strip 19. The lever 35 is then thrown upwardly or downwardly, as the case may be, to throw the pinion 32 into engagement with the idle-pinion 27 or the pinion 23 upon the outer end of the roller 21. The spring 29 upon one end of the shaft 28 is then wound up by turning said shaft 23 by the application of a suitable key to the rectangular extension 29 on said shaft. When this has been done, the device is ready for operation. It should be stated, however, that the lugs 4G upon the rail 45 are located at each station at which the train is to be stopped. The roll 19 is so adjusted in the firstinstance that the next station at which the train stopsis visible through the opening 2 in the casing 1. As the train proceeds this remains in view as a constant indicator to the passengers. When the station indicated thereby is reached, however, the lower arm of the bell-crank lever 44 is brought into engagement with the lug or projection 4G on the rail 45, and, through the pitinan 43, the outer end of the trip -lever 41 depressed. This raises the inner end of said trip-lever, and, by engagement thereof with the flanged arm 39 on the escapement pawl or lever 38, raises said pawl and permits the shaft 28 to move the distance of one tooth of the ratchetwheel 37, the said shaft 28 being driven by the spiral spring 29 upon one end thereof. The motion of the shaft 28 is transmitted through the cog-wheel 31 and sliding pinion either directly or indirectly, according to whether said pinion is in engagement with the idle-pinion 27 or the pinion 23 upon the outer end of the roller 2l. The turning of the roller 21, by reason of the frictional connection between it and the roller 20, shifts said band the distance of the space between two of the printed stations thereon and exposes the next station at which the train stops to view through the opening 2. This operation is repeated as each station is reached and passed. \Vhen the train reaches the end of its route, it is merely necessary, in order that the operation of the bell-crank lever -1-1 shall shift the roll 19 in the opposite direction, for the lever 35 to be moved so as to throw the sliding pinion 32 out of Contact with the idle-pinion 27 into contact with the pinion 23, when the motion of the sha-ft 28 in the same direct-ion will turn the roller 21 in the opposite direction.

In Figs. 6 and 7 I have illustrated the form of device which will be employed for operat- IIO ing the bell-crank lever 44 upon an ordinary steam-railway. When my device, however, is used upon electric railways where a U-rail instead of a T-rail is employed, the construction and operation will be slightly different.

vThis is clearly illustrated in Figs. 8 and 9.

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