To all w om it may concern:

Be it nown that I, EMERYYV. Milton, :1

citizenof the' United States of America,

' StationIndicators, of which the following 'station indicator particularly designed for and State of Indiana, have invented certain simple in construction, durable, -applicable ings forming part of this specification,

attachment, Fig.4 is a side elevatipn of the residing at Hammond, in the county of Lake new and useful Improvements in Street and is a specification, reference being had therein to the accompanying drawing.

This nvention relates to a. street and electrically operated Street car systems, and the primary object of the invention is to provide a car with an indicator for display ing the name of a streetor station within the car as the car approaches the-street or the next street or station and'obviating the necessity of the conductor or brakeman of stations to notify the passengers. i Another object of the invention is to provide. a street indicator that will be automatically operated to' display the names of streets as they are approached by the car, 1 the indicator l-being arranged in the car whereby it can be readily observed by the passengers.

'A further object .of the invention is to furnish a street indicator with novel means in a manner as will be hereinafter set forth' whereby the movement of the display apron can be easily reversed as is necessary where a car returns over the same route. I A still 'further' object of the invention is to accomplish the above results by a street and station indicating mechanism that is the car callin the names of the streets or I to various types of cars operated by a trolley. system, and highly efficient for the purposes for which it is intended.

With these and such other objects in view as may hereinafter appear, the .invention consists, of the novel construction, combination and arrangement of parts tobe herein after specifically described andthenclaimed.

Reference will now be had to the drawwherein like numerals of reference designate correspondin parts throughout the several views, in w ich:'

Fig. 9 is a similar view taken on the line W-W of Fig. 6, Fig. 10 is an elevation of a portion of a movable arm used in connection with the indicator, and Figjll is a longitudinal sectional view of a portion of a spring actuated roller.

In the drawings 1 denotes a street car of an electrically operated trolley system, the 5 car having a trolley pole 2 provided with a l trolley wheel 3 adapted to travel against a station, thereby notifying the passengers of g trolley wire 4. Connected to the trolley wire 4 at streets or stations along the route of the car is a hanger, comprising a bolt 5 having a lower hook-shaped end 6 to receive the trislley wire 4, and clamped in engagement with the lower hook-shaped end 6 of the pole 5 is a member 7 provided with lateral extensions 8 having depending blades 9.

The member 7 is retained in engagement with the wire 4 and the hook-shaped end 6 of the bolt 5 by a nut 10 screwed upon the The blades 9'are formed integral withthe lateral extensions 8 and are located a sufiicient distance from the trolley wire 4 so as not to interfere with the trolley wheel 3.

Mounted upon the trolley pole 2 adjacent to the wheel 3 is an elliptical sha d bearing 11' and journaled transversely 0 said bearing is a yoke '12 provided with

cranks

13 and 14, said cranks being connected by retractile springs 15 to the trolley pole 2.; The upper ends 16 of the yoke are adapted to contact with the blades 9 of the hanger and by ridin under said blades swing the yokes sufiicient y-to pull upon a cable 17 attached to the crank 14. The cable 17 extends through an opening in the roof of the car 1, under a revoluble-sheave 18 suspended from the roof of the car, over a 'revoluble sheave 19, carried by the roof of the car and is-attached to the eye-bolt 20 of the indicator located withinthe car.

The indicator comprises a rear wall 21 suitably secured to the inner side of thefront wall of the car, whereby it can be easily observed by the occupants of the car, the. rear tions ofamovable apron within the indicatorcasingcan be observed. The opening 33 is provided with a transparent plate 34 retained over said opening by a frame 35 secured to-the inner side of the wall 26. The end.wall 24 is provided with a segmentsha ed slot, 36 providing clearance for the .eyew olt 20 and this eye-bolt is connected to the'lower end of a crank 37 mounted upon a shaft'38 journaled in an arm 39,.pivotally mounted upon a pin 40, carried by the inner side of the wall 24. Upon the shaft 38 there is mounted-a wheel 41 having equally spaced-notches 42, and beside the wheel 41 3 is a'fixed gear wheel 43. The gear wheel 43 is adapted to normally mesh with a gear. wheel mounted upon a shaft 45 ournaled in the upperend of the arm 39.

Engaging the notched wheel 41 is a pawl 46 ,pivotally connected to the side of the crank 37'adjaeent to the lower end thereof," as at 47, said pawl being normally held in engagementwit'h the notched wheel 41 by a compression spring 48, carried by a right angular extension 49 of the crank 37.

Engaging in. one of the notches of the wheel 41 isa locking pawl 50, carried by the upper end of a rod 51 slidably mounted in brackets 52, carried by the lower end of the arm 39. Arranged transversely of the rod 51 between the brackets 52 is a pin 53, and

encircling the rod 51 between the/pin 53 and the-lowermost bracket 52 is a coiled compressionspring 54 adapted to normally re- 7 tain the rod 51 in an elevated position with the locking pawl thereof 1n engagement .with the notched wheel 41.

The upper end ofthe crank37 is cut away, as at 55 and pivotally connected to said crank adjacent to the cut away portion by a pin 56 is a dog'57 adapted to engage a lug 58, carried by the-rod 51 and shift said rod downwardly to move the locking pawl 50 out of engagement with said notched wheel, as will hereinafter appear.

Journaled in the

walls

24 and 25 of the in dicator casing are two longitudinal shafts 59 and mounted upon said shafts are drums 6O covered with rubber or a similar materialfil. Mounted upon the shafts 59 adjacent to the end wall 24 and at the ends ofthe drums (30 are gear'wheels (Hand 63, the purpose of which will presently appear.

Mounted in the end walls 24-and 25 ada'ct uated.

jacentto the upper edges thereof and-con tiguous to the rear wall 21 of the indicator casing is a rod 64 and mount-ed upon said rod is a spring held roller '65 to which is attached and wound thereon an apron 66. This apron is adapted to pass upwardly over the uppermost drum 60, downwardlyunder the lowermost drum and wind'on to a spring held roller 67 loosely mounted-upon a shaft 68. arranged between the

end walls

24 and 25 adjacent to the bottom-plate 23. The

spring held

rollers

65 and 67 are of a conventional form embodying a cylindrical shell 69 inclosing a coiled spring 70 which encircles the shaft of the roller, said spring the names can be observed by the occupants-t of the street car 1.-

The lower end of the arm 39 is provided with a right angular pin 71 extending through a slot 72 rovided therefor in the end wall 24, said pin having a knob .or suitable handle 72.

" Pivotally connected to the outer 'side of the end wall 24 adjacent to the'slot 72 is a lever 75'having a hook-shaped end adapted to engage the pin 71 and hold the arm 39 in an adjusted position at one end of the slot, the end of the lever holding the pin in an adjusted position at the opposite end. of the slot. The lever 75 is provided with,

a small handle or knob 76 whereby it can be easily shifted out of engagement with the pin 71, when it is desired to move the pin to reverse the direction of the movement of the apron 66.

Operation :The apron 66 is adapted to be automatically and intermittently shifted, and this is accomplished by the upper ends 16 of the yoke. 12 contacting with theblades 9 'and as the upper ends of the yoke ride under said blades, the yoke is rocked sulficiently to pull upon the cable 17 which is atta'cl'icd to the eyebolt 20 of the crank 37. As the crank 37 is moved upwardly toward the upper end of the slot 36, the spring pressed pawl 46 shifts the notched wheel 41 and thereby rotates the shaft 38 in the arm 39. lVith the gear wheel 43 of the shaft 38 in engagement with the gear wheel 63, the lower drum (30 will be rotated and as both of these drums friction-ally engage the apron 66, said apron will be intermittently moved atthe opening 33 each time the crank 37 1s When the cranlt37 is actuated, the dog 57 engages the lug 58 and shifts the rod 51 downwardly, thereby moving the locking pawl 50 out of engagement with the notched wheel 41 and allowing said wheel vided with a sight opening,

.gravity, the pawl 57 will yiel to rotate. Inasmuch that the crank 5' swings upwardly when actuated, the dog 5? will ride over the lug 58 and when saidcrank is restored to its normal osition by g and ride over the lug 58 and assume its normal posi-. tion'with respect to said lug. lVhen it is desired to reverse the movement of the apron 66 infront of the opening 33, the arm 39 is shifted through the medium of the pin. 71 and the knob 72 thereof. When the arm 39 is shifted, the gear wheel 43 is moved out of engagement with the gear wheel'63 and the gear wheel 44 at the upper end of said arm placed in engagement with the gear wheel 62 of the upper drum with the gear wheels43 and M always meshing, a reverse movement will be imparted to the apron 66.

What-I claim is:- r

A street and station indicator comprising a casing having the front wall thereofprorollers journaled in said casing, an apron traveling over said rollers and provided with indications for exposure through said sight opening, an

' Witnesses:
