SIGNAL DEVICE FOR STREET-CARS.

Toljttll whom it may concern.-

Be it known that I, HARRY H. MILLER, a

citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have unventeda certain new and useful Signal Device for Street- Cars, of which the following issuch a full, clear, and exact description as will enable any one skilled in-the art to which it appertains to make and use the same, reference being had to the a'ccom paiiying drawings, forming part of this specisuch approaching car'being obscured from the passengers vision by the car from which he has just descended. I I

The object of my invention is to provide means whereby the passenger may be warned of the approach of the car from the opposite direction on the adjacent track. I In carrying out my .invention Iprovide-at the rear end of the car a barrier, which is normally out of operative position, but which is within control of the motorneer, so that'said barrier may bethrown into position to block 0. the athat the rear of the car to the adjacent trac said barrier being, preferably provided both with visual and audible danger-sig als.

In the accompanying illustrate one form of signal device'ma. e in 3 5 accordance with my invention, Figured isa side view of the signal device, together witha portion of a street-car to which the same is attached. -Fig. 2 is a' diagram illustrating the bell-circuit, and Fig. 3 is an enlarged sec- 4 tion through the signal device.

Like-marks of reference refer 'to. similar parts in the several views of the drawings.

oted in the casing 10 at 11 is an arni 12, which forms the barrier for obstructing the path to theadjacent. track. This arni 1:2 carries'at its extremity a flag 13', which forms a visual danger-signal. The lower end of the arm 12 is provided with a weight 14, which normally holds the arm 12 retracted within the casing" 10 in a substantially vertical position, asv shown in Fig. 3. The weight 14 is extended rearwardly, as shown at 1.5 in Fig.

3, and this extension 15 has attached-to it a cord'16, which passes u througlithe casing 10 6 5 and over a pulley 17, situated near the upper end-of said casing. After passing overithe pulley 17"cord 16 extends under the platform hood 9- and the roof of the car to the front platform and. terminates within the 7p reach of the motorneer. 18 is a bell,whicli .is adapted to form an audible danger-signal. This bell 1.8 is contained in the circuit 19, which, is' preferably a branch of the usual bell-circuit provided in the car to enable the 7 5. passengers to signal for the car to stop. ()iie terminal of the circuit 19 is secured to a contact-plate 20, arranged within the casing 10, and the other terminal is secured to-the-pivot 11 'of the arm 12. This pivot 11 also carries a small contact-arm 21, adapted to engage with contact-plate '20 when the arm 12 is lowered to horizontal position, and so complete circuit 19 to ring bell 18, the said circuit being broken when the arm 12 is in its 5 normal position. I The operation of my device .is obvious.

When themotornee'r stops the car to allow alight,- if anothercar is aperates the cord 16, thus causing the arm 12 to be thrown out of the casing 10 intoa horizontal position, as shown in Fig. 1-, thus forming a barrier acrossthe path at the rear of the car. At the same time the circuit 19 is com- 5 pleted, so .as to ring the bell to give an audible signal, and the fiag 13 forms a visual signal to warn the passenger of the approaching car.

When the'cord 16 is released, the arni 12 is returned to its normal positionin the casing 10 I 00 by means of the weight 14.

I Having fully describedmy invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
