STREET=CAR SIGNAL.

SPECIFICATION forming part of Letters Patent No. 358,484, dated March 1, 1887.

Application filed October 26, 1885. Serial No. 189,910. (No model To 01. whom it may concerns.

Be it known that 1, CHARLES F. RooERs, a citizen of the United States, residing at Boston, in the county of Suffolk and Stateof Massachusetts, have invented a new and useful Improvement in Street-Oar Signals, of which the following is a specification.

The object of my invention is to provide a means for guarding against accidents occurring to persons alight'ing from a streetcar and stepping off in front of a car coming in the opposite direction.

The invention consists in the combination, with a street-car, of a rotatable signal on the roof thereof, the usual bell-strap, and intervening mechanism, substantially as hereinafter claimed, or the equivalent thereof, by which a pull on the bell-strap actuates the signal. 1

Referring to the accompanying drawings, Figure 1 is a front view of a street-car with my invention applied thereto. Fig. 2 is a partial longitudinal section of the same. Fig. 3 is a front view of a casing inclosing my invention. -Fig. 4 is a vertical section of the same. Fig. 5 is a horizontal section taken on line .00 m of Fig. 3. Fig. 6 represents a means employed for actuating the signal.

A represents the body of a street-car.

B is the upper part of the roof.

0 is a casing secured to the roof and provided with an aperture, D, in front, to be covered with glass to exclude dust, water, 850. Within the casing O is a casing, E, having holes 6 in its opposite sides, to be opposite the glass in aperture D when properly turned. This casing E is arranged to revolve, and is provided with a top or cover, E, to the upper part of which is secured a sign, F, having the word Stop on both sides. To the bottom of the casing E is secured a spindle, G, that passes down through the roof B, and is provided on its lower end with a cog-wheel, H, that gears with a cog-wheel, I, carried on a pin or stud, J. To thecog-Wheel l is secured a ratchet-wheel, K.

L is a lever fulcrumed to the inner side of the car at L, and is provided on its upper end with a pawl, M, that engages with the ratchetwheel K when the cord or strap N is pulled for the display of the signal F. A spring,

P, attached to the lever and to the car, serves to draw the lever back to its normal position.

within theinner casing, E, is placed a lamp or lantern, Q, provided with bulls-eyes, so that the signal can be used at night. The glass or bulls-eyes may be of some peculiar color, to indicate that the approaching car is to stop; or the word Stop may be marked on the glass.

When the signal for the approaching car is not required,it is turned so as to extend lengthwise ot' the car. When the signal for the approaching car is required to be displayed, the cord or strap N is pulled, causing the upper part of the lever L to actuate the pawl M (see Fig. 6) and the ratchet-wheel K, thus causing the cog-wheell to turn part of a revolution and carry the wheel H and with it the casing E, so as to bring a bnlls-cye opposite the opening D and also display the sign F. The cord N is shown connected with the bell-strap S, so that when the conductor pulls the strap to stop the car the signal will be operated at the same time.

WVhen the signal to start the car is given,the pawl M, which has been drawn back by the spring P, will again engage the ratchet-wheel K and turn the latter and signal F another part of a revolution, so that the signal will he no longer shown at the front of the car.

Instead of two cog-wheels, only one may be used, the lever L being arranged to operate directly on a wheel on the spindle G.

' What I claim as my invention is The combination, with the bell-strap of a street-car, of a lever connected thereto, a ratchet-wheel actuated by a pawl on said lever, and a rotatable signal above the roof of the car, connected with the ratchet-wheel, so that the pulling of the bell-strap shall actuate the signal, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

C. F. ROGERS.
