ELECTRIC-CAR GEAR.
SPECIFICATION forming part of Letters Patent No..4 20,54=4, dated February 4, 1890.
Application filed May 13, 1889.
tact with friction-wheels attached to the traction-Wheels.
The object of the invention is to guard against the slipping of the friction-pulley on its bearings on the friction-wheels; and to that end the invention consists in the employment of a sand-hopper on the car having its discharge-spoutsin front and rear of. the friction-pulley, and gates adapted to open and close said spouts, all as hereinafter more fully described, and specifically set forth in the claims.
In the annexed drawings, Figure lis avertical longitudinal section taken at the inner side of the traction-wheels of a car-gear embodying my improvements. Fig. 2 is an inverted plan view of the sand-hopper, showing the levers for operating the gates of said h0pper from opposite ends of the car, and Fig. 3 is a vertical longitudinal sectional view of a modification of my invention.
Similar letters of reference indicate corresponding parts.
B B represent two of the traction-wheels on one side of the car, which wheels have rigidly attached to their inner sides or formed integral therewith the friction-wheels O 0, concentric with the traction-wheels.
A denotes the friction pulley, which is either mounted directly on the shaft of the electromotor or on a counter-shaft receiving motion from said motor, said friction-pulley being with its periphery in contact with the peripheries of the friction-wheels, and by said contact transmitting motion to the traction-wheels when said pulley is driven by the motor.
In the operation of said class of car-gears Serial No. 310,584. (No model.)
it has been found somewhat difficult to prevent the friction-pulley from slipping on its bearings on the friction-wheels, and in order to obviate this defect I attach to the car D, in a suit-able,position and in any proper and convenient manner, a hopper H, in which tohand-levers Z Z, connected to the car thereat,
each of which levers is connected by a rod 0 to a lever d, which in turn is connected with the gate 12 at the farther side of the friction-pulley A, as illustrated in Fig. 2 of the drawings.
When it is found that the friction-pulley A slips on its bearing on the wheels 0 C, it is readily checkedby opening the gate Z7, which allows the sand to run from the hoppr H to the peripheral face of the friction-wheel G at the rear of the friction-pulley A, and the sanded face of said wheel affords a secure frictional hold for the pulley A.
It is obvious that the described sanding apparatus can also be employed in connection with a friction-pulley P, engaging the top of a single frictionwheel O on one of the traction-wheels B, as illustrated in Fig. 3 of the drawings.
What I claim as my invention is- 1. On an electric car having friction-pulleys in contact with friction wheels and transmitting motion to the traction-wheels, a sand-hopper carried on the car and having discharge-spouts in front and rear of the friction-pulley, and gates adapted to open and close said spouts, as and for the purpose set forth. I
2. On an electric car having friction-pulleys in contact with friction wheels and transmitting motion to the traction-wheels, a sand hopper carried on the car and having its discharge-spouts in front and rear of the In testimony whereof I have hereunto friction-pulley, gates adapted to open and signed my name this 9th day of May, 1889.
