EDWARD SOHUPP, OF LOS ANGELES, CALIFORNIA.

INDICATOR FOR CARS.

Application filed. December To all whom it may concern:

e it known that I, EDWARD Sc-HUPP, a citizen of the United, States, residing at Los Angeles, in the county of Los A geles and State of California, 7 new and useful Improvements in for Cars; and I d V be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in Indicators indicating devices for cars.

. streets or 7 sectional view The object of the invention is to provide an indicator of this character adapted to be automatically operated as the car approaches a street or station, whereby the name of such street or station will be indicated to the passengers in the car.

A further object is to provide means whereby the operating mechanism may be reversed to properly display the names of the stations upon the return of the car.

lVith these and other objects in view, the invention consists of ce tain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claims.

11 the accompanying drawing, Figure 1 is a diagrammatic view of a portion of a car and trolley are showing the arrangement of the electric contacting devices whereby the ind'cator is operated; 2 is a front view of my improved indicator; Fig. 3 is a vertical through the casing of the in dicat-or showing the arrangement of the operating mechanism therein; Fig. 4 is a similar view taken at iighteangles to and on the line 44: of big. 3 1 and 5 is a similar view taken on the line 5-5 of 3.

Referring more particularly to the drawings, 1 denotes the casing of the indicator, in the upper portion of which is arranged an upper winding roll, 2, and a lower winding roll, 3, around which is wound the belt or fabric strip, 4, containing the names of streets or stations. The strip, 4, passes under and over lower and upper guide rods, 5, so that a portion of the strip while passing between the rods will be held in a vertical plane so that the name may be readily observed through the display opening in the frame or casing.

In the lower portion of the casing is arranged an operating shaft, 7, with which,

adjacent to one end, is connected a spring have invented certain Specification of Letters Patent,

motor, 8, which may be of any suitable construction adapted to rotate the shaft, 7. (m the shaft, 7, is also mounted a spur-gear, 9, with the opposite sides of which are adapted to be engaged spur gar pinions, 10 and 11, which are mounted on the ends of supporting arms, 12, the upper ends of which are pivotally connected to the casing in any suitable manner.

On the shaft of the connected to said which is connected pinion, 10, or fixedly pinion, is a pulley, 13, by a belt, 14, to a pulley, 15, on the shaft of the lower winding roll, 3, whereby when the pinion 10 is thrown into engagement with the gear, 9, motion will be imparted to the winding roll, 3, to wind up the strip thereon and thus display the name of the street or station which is being approached by the car. On the shaft of the pinion, 11, or fixedly connected to said pinion, is a pulley, 16, which is connected by a belt 17, to a double pulley, 18, which is loosely mounted on the shaft of the lower winding The pulley, 18, is connected by a short belt, 19, to. a pulley, 20, fixedly mounted on the shaft of the upper winding roll, 2. By this arrangement of the belts and pulleys, the pinion 11, when thrown into engagement with the gear, 9, will operate the upper winding roll to cause the strip to be wound in the opposite direction from that in which it is operated by the engagement of the pinion, 1.0, with the gear, 9. The pinions, 10 and 11 are thrown into and out of engagement with the gear 9 by means of operating rods, which are connected at their upper ends to the supporting arm, 12, of the pinions, 10 and 11. The lower ends of the rods, 20, are threaded and project through the bottom of the casing, 1, and are engaged by operating wheels, 21, which are suitably connected to the casing of the indicator. By this arrangement when the car reaches the end of the route, the conductor or motorman may disengage one pinion from the gear and throw the opposite pinion into engagement therewith by turning the wheels, 21, to shift or change the relative position of the rods, 20, thus causing a reverse movement of the name strip so that when the car returns over the route, the names of the stations or streets will be properly indicated. The shaft, 7, of the operating mechanism is held against movement by the motor connected thereto, by means of a locking mechanism comprising a ratchet disk, 22, which is fixedly mounted the operating shaft 7 may be 2 connection with 1 I claim as new and desire to secure by Let ters-Patent, is:

1. In an indicating device of the character described, upper and lower winding rolls, a name strip adapted to be wound and un wound on said rolls, an operating shaft, a gear on said shaft, an operating pinion. pivotally, mounted at each side of said gear, means to move either of saidpinions into and out of engagement with the gear, means to connect said pinions with said winding rolls whereby motion is imparted to the latter from said gear to cause the same to wind the strip in the proper direction, a motor operatively connected to said gear, locking mech anism to hold said shaft against rotation and electro-magnetic means to periodically and automatically release said locking mechan on the shaft, 7, and is provided with a series of teeth, 23, which are engaged by a stoppawl, 24, which is suitably pivoted upon an arm, 24, fixed to the casing of the lndicator and is adapted to be engaged with the notches, 23, of the ratchet disk preferably by a light spring, 25.

The pawl or dog, 24, has arranged thereon an armature, 26, of an electro-magnet, 27, arranged in an electric circuit, 28, one terminal of which is connected to a contact 29 secured to the upper end of the trolley pole, 30. The contact, 29, is adapted to be brought into engagement with a contact, 31, arranged on the trolley wire preferably midway between the stations or streets along the route of the car so that as the car approaches such station or street, the contact, 29, will be engaged with the contact, 31, and electricity ism.

conducted therefrom to the electro-magnet, 2. In an indicating device of the character which will energize the same and cause the described, a pair of winding rolls, a name pawl containing the armature, 26, to be restrip adapted to be wound and unwound on tracted out of engagement with the locking said rolls, an operating shaft, a gear mounted notches of the wheel or disk, 22, thus releason said shaft, a pair of pivotally. mounted ing the operating shaft, 7, and permitting the motor connected therewith to rotate the pinion supporting arms, a pinion carried by each of said arms, an operating rod connectsame, which motion is transmitted through ed to each of said pinions supporting arms one or the other of the pinions, 10 or 1]., to whereby they may be actuated to engage one the winding rolls, whereby the strip will be Wound in the proper direction to display the name of the street or staion being apor the other of said pinions with said gear, operating wheels having a threaded engagement with said rods whereby the latter are preached. The shaft of the lower roll 3 and Y provided with crank handles as indicated by the dotted lines so that the
