ELECTRlCALLY-OPERA TED STREET-INDICATOR FOR CARS SPECIFICATION forming part of Letters Patent No. 514,878, dated February 13, 1894.
Application filed June 23, 1 8 93.
To Ml whom it may concern: f
Be it known that I, HENRY O. BARKER, of
the city of St. Louis, in the State of Missouri,
have invented a certain new and useful Improvenient in Electrically-Operated Street- Indicators for Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to a street indicator for cars, operated through the medium of the trolley or contact pole of an electrically driven car; and my invention consists in features of novelty hereinafter fully described and pointed out in the claims.
Figure I is a side elevation of the upper portion of a street car, illustrating my indicator applied thereto. Fig. II is a front elevation of a portion of the indicator box, part being broken away to show the interior, the
. traveling indicator ribbon, and the mechanism by which said ribbon is carried. Fig. III is a vertical section through the indicator box,
7 taken on line IIIIII, Fig. II. Fig. IV illustrates a modification, in which the indicator is operated mechanically on the depression of the trolley. Referring to the drawings, 1 represents a car carrying an ordinary trolley 2, forming contact with the conductor 3, and on' the conductor 3 are cam blocks 3*, there being one of said blocks near each of the streets crossing the line of railway over which the car 1 runs. .As the trolley passes under one after another of the cam blocks 3*, it is depressed and operates the indicator as will be hereinafter set forth.
It will be understood, by reference to the drawings, that there are'two indicators on each car, there being one for each way the car travels. v
4 represents the indicator boxes within which, mounted upon rollers 5, is a traveling ribbon 6, upon which is marked the names of the thoroughfares crossing the line of rail-' way on which the car 1 travels.
. 7 is a sight opening, through which the names of the streets may be observed as they are consecutivelybrought before the opening,
through the action of theindicator. Mounted on a bracket 8, on the exterior of the box 14,
' shaft of the upper roller 5.
Serial No. 478.668- (No model.)
is a magnet 9 within which is arrangeda movable core 10, and extending from the core is a bar 11, whose opposite end is' arranged to move in a hollow sleeve 12 at the rear of the box' t. On the upper side of which bar is a spring 13 that carries a catch 14, for engagement with a ratchet-wheel 15,mounted' on tho When a current passes through the magnet 9, the core 10 is drawn into the magnet, and it is through the movement of the core 10 being so drawn that the roller 5 isturned, carrying the indicator apron or ribbonaround.
, 16 is a dog for engagement with the teeth of the ratchet wheel 15, to prevent retrograde movement of the roller 5, and 17 is a spring connected to the sleeve 12 and to the bar 11, which spring is of sufficient strength for the purpose of drawing the core 10 partiallyfrom 7c the magnet when the electric circuit has been broken, as will be hereinafter explained, and at which time the magnet offers no resistance, the action of the withdrawal of the core carrying the catch 14 back to the next notch on the ratchet wheel 15, so that as the circuit is again opened at the succeeding crossing, causing the core to be again drawn into the magnet, and the roller 5 is again turned to move the indicator.
I will now describe the means of conveying the circuit from the electrical conductor 3, through the magnet 9.
18 represents conducting Wires running from the magnets to boxes 19, secured to the 8 roof of the car and ending in contact points within said boxes, and 18 are the ground.
wires. In the boxes 19. are spring contact plates. 20 adapted to be thrown in contact with the ends of the conducting wires 18. On the 0 upper side of the car roof are barrels 21, through which pins 22, normally supported by springs 23 pass. On the trolley 2 isa bar 24, through the medium of which a pin 22 is depressed, causing the contact plate 20 to be 5 depressed into contact with the end of the conducting wire 18, as the trolley passes under the cam block 3 secured to the conductor 3, and supported by the crossing wire at each intersecting crossing along the line of rail- 10o way over which the car passes.
In the form of device shown in the modification, (Fig. IV) the pin 22 operates a bellcrank lever 25, which in turn moves a rod 26, and said rod being connected to the bar 11 operates the rollers mechanically on the depression of the trolley.
I claim as my invention 1. In combination with an indicator carried by a car, and a cam block located on the conductor, or trolley wire of an electric railway, a trolley arm having a contact piece, and a contact point mounted on the car, and which has electrical connection with said indicator, whereby when the trolley engages said cam, said indicator is operated, substantially as set forth.
2. The combination in a street indicator, of the rollers carrying a traveling indicator, a magnet, a core in said magnet carrying a catch, a ratchet wheel on the shaft of one of said rollers with which. said catch engages, and an electrical conducting wire connected to said magnet, and means whereby the elec' trical current is opened and closed over said conducting wire in the movement of the trolley or contact piece of an electrically driven car; substantially as and for the purpose set forth.
3. The combination in a street indicator, of the rollers carrying a traveling indicator, a magnet, a core in said magnet carrying a catch, a ratchet Wheel on the shaft of one of said rollers with which said catch engages, and an electrical conducting wire connected to said magnet, and means whereby the electrical current is opened and closed over said conducting wire in the movement of the trolley or contact piece of an electrically driven car; said means consisting of a spring supported pin for contact with said conducting wire, and a bar on said trolley to press said 40 pin into contact with said wire; substantially as and for the purpose set forth.
