STATION-INDICATOR.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed May 11, 1908. Serial No. 432,209.

To all whom it may concern:

Be it known that I, ROBERT A. HATE HORNE, citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Station-Indh cators, of which the following is a specification.

My invention relates to new and useful improvements in station indicators. V

The object of the invention is to provide an indicating device comprising a web and means for moving the same across an opening to exhibit. intermittently the names of stations or streets, and more particularly to provide means whereby the web is manually operated in one direction and mechanically operated in the opposite direction.

With the above and other objects in view, my invention has relation to certain novel features of construction and operation an example of which is described in the following specification and illustrated in the accompanying drawings, wherein:

Figure 1 is an elevation of one side of the station indicator, a portion of the casing being broken away to show the mechanism.

Fig. 2 is a partial top view of the mechanism the portion shown being that seen in Fig. 1. Fig. 2 is an end view of that portion of the indicator mechanism, illustrated by Figs. 1 and 2. These three views serve mainly to make clear the spring operated mechanism whereby the indicator is driven on the return trip of the car in which it is installed. Fig. 3 is an elevation of the opposite side of the indicator to that shown in Fig. 1. The side wall of the auxiliary casing, which contains the mechanism for manually operating the indicator on the out trip of the car, is omitted to show said mechanism and a portion of the main casing is broken away, showing one of the spools and the frame. Fig. 1 is a horizontal sectional view of the parts seen in Fig. 3 the mechanism in the auxiliary casing, and a portion of that in the main casing being shown. Fig. 5 is a detail side view of a pawl and ratchet mechanism positioned in the auxiliary casing, and serving to transform a manually produced lever movement to a rotary motion of one of the spool spindles. Figs. 6 and 7 are side and top views smaller casing t permanently secured to the supporting board. At its forward end the casing 8 is provided with a glass covered exhibiting opening 5 through which the names of the streets or stations are exhibited.

In the casing 3, a base board 6 is secured to the bottom thereof and securely supports side frame bars 7 between which spools 8 and 9 are mounted to revolve. The forward ends of the frame bars support horizontal rollers 10 and 11, one above and the other below the opening 5. A web 12 on which the names of the streets or stations are transversely placed has one end secured to the rearward spool 8. The Web is passed forward above thespool 9, over the roller 10, down and under the roller 11. to the spool 9 to which it is attached. In this Way the web is caused to travel vertically across the opening 5. This web is first wound about the spool 9 and wound upon the spool 8 as y it is intermittently moved to display or exhibit the names.

In orderto wind the web upon the spool 8 the same is provided with a laterally extending shaft 13projecting into the casing 4t and carrying on its outer end, a clutch gear 1 1. This clutch gear is adapted to be engaged by a clutch gear 15 slidably mounted on, and adapted to turn with a shaft 16 supported in a standard 17 mounted on a base board 18 secured in the casing 1. This shaft carries on its outer end, a ratchet wheel 19 and a pawl lever 20 carrying a suitable spring pressed pawl 20 enga ing the said ratchet wheel, the outer end 0 the lever having connection with the lower end of a. coiled spring 22 secured to the top of the casing. The pawl lever swings in a guard frame 28 secured to the standard 17, and serving to limit the upward motion of the lever produced by the spring 22. A

to the lower end of the lever 20 and passed over a pulley 26 secured to the casing, and thence passes out of the casing through an aperture 27, where it is suspended within.

reach of the conductor.

It is obvious that when the cord 25 is pulled down by suitable means, the lever20- is swung downward against the tension of the spring '22, revolving the ratchet wheel 19. and turning the shaft 16. When the cord 25 is released, the spring 22 returns the pawl lever :to its normal position, the pawl lever 20 slipping over the teeth of the ratchet:wheel which is held against backward rotation by the spring pressed pawl 24. Motion thusimpa-rted to the shaft 16 is transmitted to the shaft;l3 by the clutch gears 14 and 15. Each. time the ratchet wheel-.191isrotated, the spool S will be rotated winding the web 12 thereon. The web is thus intermittently moved so as to bring each time, the name of the succeeding street or-station into view .at the opening 5. This operation-is carried out until the end of the run has "been reached when the web will have beennwoundupon the spool 8.

In order to store up power to rewind the web upon thespool 9 and exhibit the names of the. streets or stations on the return run in their proper order, I have provided aspring motor. In carrying out this construction. a pinion 28 is mounted upon the spindle 28 of the spool 9 and meshes with av gear 29 mounted on a shaft 30 supported in the side frame 7 and upon a standard 31. The shaft 80 projects through the frame and carries a .pinion 33 which meshes with a gear 34 mounted :on a .shaft 35 passing through: the side frame 7 and carrying a 1 pinion 86 which meshes with a rack-bar 37 adaptedatotravel horizontally in the support '32 attached to thesideof the standard 31. This rack-bar is connected at its rear end toaipair of horizontally disposed coiled springs-38connected at their rear end to a post 39. As the spool 9 is unwound it is revolved from left to right with relation .to Fig.4, revolving the gears and pinions in the direction of the arrows which causes the rack-bar 37 to be moved forward and the springs extended. This extension of the springs is carried :out during the intermittent :movement of the spool 8, and when the clutch gears are separated, have suflicient tension to draw the rack rearward and revolve the pinions and gears in the opposite direction as well as the spools and wind the web on to thespoolt) from the spool 8.

It :is obvious that it is desirable to intermittently move the web as it is rewound and in order to do this I provide means for sliding the clutch gear 15 out of engagement with the clutch gear 14 which permits the springs to move the rack-bar and operate the spool, it being understood that the parts remain stationary so long as the clutch gears are in engagement, for the reason that the ratchet wheel 19 is held against backward movement by the spring pressed pawl .23.

In order to disengage the clutch gears 14 and 15, a groovedsleeve 40 is provided to the last named gear, and the groove of said sleeve is engaged bya yoke 41 carried at the extremity of one of the arms of a bell crank lever 42. This lever is pivotally mounted in a horizontal position upon the top of a rigid upright post 43. A cord 44, which is attached to the other arm of the lever, after passing over pulleys 45 and 46 passes out of the casing and is suspended within reach of the conductor.- By pulling this cord at the proper intervals upon the return trip, the clutch gears will be disengaged, and the web will be set in motion by the action of the springs 38. The clutch gears are normally held in engagement by the action of a coiled spring 47 upon the shaft 16. The disconnection of the clutch gears is timed to )ermit the necessary travel of the web, as urther rotation and movement will be prevented when tension upon the cord 44 is relieved and the clutch gears are made to mesh by the spring 47.

I .am aware that changes may be made in the arrangement and proportion of parts and details of the herein described indicator, without sacrificing the advantages or departing from the spirit thereof, and I therefore reserve the right to make such changes and alterations in said device as fairly come within the scope of the following claims.

lVhat I claim, is:
