GEORGE HERBERT CONDIOT AND VICTOR ANGERER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNORS TO THE ELEC RIC CAR COMPANY OF AMER- ICA, OF SAME PLACE.

ELECTRIC CAR.

SPECIFICATION forming part of Letters Patent No. 400,830, dated April 2, 1889. Application filed June 20, 1888, Serial No. 277,670. (No model.)

D is a regulator or switch for controlling the speed and power of the motors, and, as shown, controls the amount of current passing from the battery E, which may be of the secondary type. The current is fed from the battery to the regulator by wires 6 and from the regulator to the motors by the circuits 0.

The regulator D is preferably secured to the under part of the car-body, as shown in Fig. 2, and may have a door, 1), whereby its interior may be exposed for examination and repai r. The barrel of this. regulator or switch is provided on its ends with pinions (2, contained within dust-caps G. \Vorking in connection with these pinions are racks H, one of which is arranged below one pinion and the other of which is arranged upon the other pinion, so that pulling either one of the racks toward its respective platform will cause the barrel of the regulator to revolve in the same direction, for reasons hereinafter explained. The racks II have indentations or notches 7L, into which a pin, 1, is pressed by means of a spring, 1'. There are as many notches 71 as there are diiferent positions of the barrel for coupling up the motors in different ways-that is to say, in series or parallel or combinations of these. The function of the pin I is to insure the barrel being stopped at the right position. These racks H are connected with slides K under their respective platforms by means of rods J, and these slides K are guided upon guide-rods L, so as to move longitudinally on the car. A spring, M, acts upon one of the rods J and presses upon a stop, or, so as normally to return the barrel of the regulator to its off position, or that in which no current is flowing.

Arranged immediately above the slides K are socket-plates F in the platforms B B, which socket-plates have two sockets, f, for receiving the frame-work of the operatinglever.

P is the lever-frame, and has two feet, P, at the bottom and the rack p at the top, and pivoted to this frame is the operating-lever 0, having the detent o, and with its lower end extended through the socket-plate F and into a suitable hole, 7c, in the slide K. The frame P and the operating-lever are removable from the socket-plate on one platform and adapted to be inserted in the socket-plate on the other platform, so as to enable the car to be operated from either end and to enable the entire removal of all obstruct-ion from the rear or passenger platform.

It is evident that by operating the lever O in the same direction with respect to the movement of the carat either end thereof the exact same regulation will take place, and if from any cause the detent 0 is not brought home in its notch the spring M will instantly return the regulator to its next position in the direction toward cutting off the current. In this way it is impossible for the switch ,device to stand between two different connecing the battery or other source of current.

It is to be understood thatI do not limit myself to any particular detail of construction of the regulator or its connections, nor to the parts P and O,as they may be modified and varied without departing from the principles of the invention. The lever O and its detent and rack mechanism should be such that each notch of the rack p corresponds to a different position of the switch-barrel of the regulator to supply a different current to the motors, and the ratchet-teeth p are made so that the detent may snap back and catch on the tooth next in front.

Of course it will be understood that the particular source of electric current is immaterial, as it may be overhead, underground, or surface conductors in place of the secondary or primary battery shown, all of these means of electric supply being well known.
