Improvements in Motors for Street Cars.
I WILLIAM HENRY PATTON residing at 4157 Berkley Avenue in the Town of
Hyde Park in the County of Cook and State of Illinois, United States of America,
Inventor, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement, reference being bad to the accompanying drawing in which :-
Figure 1 is a side elevation, some parts being in section.
Figure 2 is a top or plan view.
This invention relates to Motors for Street Cars of the class shown and described
in Letters Patent No. 16,404, dated November 29, 1887, granted to William Robert
Lake.
The object of this invention is to provide an improved driving power for Motors of
this class, which will enable the gas engine or other motive power to be run
continuously and at a high rate of speed in relation to the speed of the cars, for
driving a dynamo, which I accomplish as illustrated in the drawings and hereinafter
described. That which I claim as new will be pointed out in the claims.
In the drawings-
A indicates the car which is mounted upon wheels B which run upon the
track C.
Dis a gas engine or other motive power.
E is a dynamo which is driven by a belt from the gas-engine D.
is a storage battery, one side of which is connected with the dynamo by the
conductor c.
Gis an electric motor, which is connected with one side of the storage battery F
by the conductor, and with the opposite side of the storage battery by the
conductor g. This side of the storage battery F is also connected with the dynamo E
by a conductor h
His the driving pulley or wheel of the electric motor G, which drives the gearing
hy the hand or cable I.
Jis a frame suspended from the axles of the wheels B.
K is a sliding or movable frame supported on the suspended frame J.
1. is a pulley or wheel mounted on the axle & of the wheels B.
M is a band-wheel or pulley mounted on an axle m supported on the inovable
frame K.
N is an idler wheel mounted on an axle supported on the frame K.
O is a second band-wheel or pulley mounted on an axle o supported on the frame K
on the opposite side of the axle & from the wheel M and axle m.
The band or cable I runs over the driving pulley H, wheel or pulley M, idler
wheel or pulley N, and wheel or pulley O, driving the wheels or pulleys M and O in
opposite directions.
P is a rock shaft which is mounted in bearings on the frame J, and is provided
with two arms p and q. The arm is connected with the movable frame K by a
link r, and the arin is connected with a lever R by means of a bar or link s.
The lever R is supported in bearings on the car floor and is provided with the usual
pawl and rack for holding the lever R in the desired position.
In use, the gas engine or other motive power drives the dynamo which generates
electricity supplied to the storage battery and electric motor by means of the
conductors e,, y, and h. The electric motor G through the wheel H and band or
cable I drives the wheels M and O and their axles as described herein before and ns
more particularly set forth in the said former patent.

page_text: The friction wheels on the axles in and o drive the wheel L, and are thrown int
and out of engagement therewith by means of the lever R and rock-shaft P, having
levers or arms p, q, and connecting link rods; but I do not limit the use of the
motor to any special form of gearing or driving mechanism.
The gas-engine, dyname,' storage-battery and electric motor inay be arranged on
the car as shown, or in any other suitable arrangement. By using a dynamo, stomge-
battery and electric motor, in connection with the gas engine, or other motive power,
the gas engine or motive power may be run at a high speed and continuously. The
dynamo can be run at a high speed by the gas engine or motive power, and the
electricity generated can be used by the motor as required, so that the speed of the
gas engine or other motive power can be regulated to snit its requirement without
regard to the speed required for the driving gear of the car, and the gas engine or
motive power can also run continuously without any loss of power in stopping and
starting as the electricity generated by the dynamo while the car is not moving, and
all electricity in excess of that required to run the electric motor when the car is
moving, is stored in the storage battery F.
By using a dynamo and electric motor the gearing of the car is driven at any
desired speed without regard to the speed of the engine or motive power, and by
using a storage battery in connection with the dynamo and electric motor, the
electricity in excess of that used by the motor is stored, thus not only preventing a
waste of power in starting and stopping the engine or motive power, but providing
a powerful current of electricity to be used when the car is started, as is necessary
from the fact that more power is required to start a car or train, than is required
after the train is in notion. An operative notor may be had by connecting the
dynamo directly with the electric motor, but it will not be as steady or as efficient as
when combined with a storage battery.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
clain is :-
The combination of the engine or motive power of a motor car for street cars,
with a dynamo E, a storage battery F, an electric motor G, conductors e, f, g, and h
and a gearing for driving the wheels of the car from the electric motor, substantially
as and for the purpose set forth.
