Improvements in Street Car Motors.
I. BURCHELL RICHARDSON MOORE, residing at 426 Armstrong Street, Kansas City,
Kansas, one of the United States of America, Railroad Conductor, 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:
་
Figure I is a top or plan view of my device. Figure II is a side view showing a
portion of the side of the car broken away, and the bottom of the car being a section
taken on line II-II, figure I, to more clearly show the parts. Figure III is a
transverse section taken on line III-III, figure I. Figure IV is a transverse section
taken on line IV-IV, figure I. Figure V is an enlarged plan view of the supporting
plate. Figure VI is an enlarged detail view of the friction rollers.
My invention relates to improvements in street car motors, and my invention
consists in features of novelty hereinafter described and pointed out in the claims.
Referring to the drawings:-
1, represents the bottom frame, or floor of a car, 2, the ends, 3, the sides, and
4, the top of the car, and 4, represents the wheels on which the car travels.
5, represents a cylinder of gas or other engine supported on a frame 6, said frame
resting on the floor of the car. 7 represents the piston rod which is journaled at its
outer end to a crank 8 on the drive shaft 9. The drive shaft 9 is supported by the
frame 6, and is provided at its outer ends with cranks 10. 11 represents balance
wheels located on the shaft 9. 12 represents an intermediate shaft located beneath
the floor of the car, the same being supported by hangers 13. 14 represents cranks
located at the ends of the shaft 12. 15 represents drive rods which connect the
cranks 14 on the shaft 12 with the cranks 10 on the drive shaft 9 by which means
motion is given from the drive shaft to the intermediate shaft 12.
16 represents a roller secured rigidly to the shaft 12.

As a
17 represents a roller secured rigidly to one of the main axles 18 of the car.
connecting medium between the roller 16 and the roller 17 when it is desired to drive
the car in a forward direction, I provide a friction roller 18, said roller being
journaled to the lower end of a swinging bar 19. The brasses 20 of this journal
being supported by a clevis 21 and bolts 22.
The upper end of the bar 19 is pivoted to an arm 22 of a crank 23. The crank 23
is fulcrumed to the upper end of a standard 24, said crank having an arm 25 to
which is pivoted one end of a link 26, the other end of the link being pivoted to
a lever 27.
28 represents a plate (see Figures II and V) which is hooked at one of its ends
over a rod 29 secured beneath the floor of the car. As an additional support the
plate rests on a boxing 30, on one of the axles 18. The standard 24 and a standard 31
are secured to the plate 28.
32 represents a bracket attached to the plate 28, to which the lower end of the
lever 27 is pivoted.
33 represents a rack secured to the standards 24, 31. 34 represents a pawl pivoted
to the lever 27, said pawl being connected to the usual rod 35 and handle 36 for
operating the same.
37 represents a swinging bar composed of two sections which are pivoted at their
upper ends to the arm 22 of the crank 23. These bars extend down below the
friction roller 18 and pass to each side of the same. At the lower end of the bars 37
are located friction rollers 38, 39, the brasses of this journal being supported by a
clevis 40, and are held to their proper position by wedges 41.
42 represents a bolt by which the lower ends of the bars are connected, and

page_text: 43 represents a sleeve on said bolt which keeps the bars at the proper position from each
other. 44 represents connecting rods between the rear and front wheels. 45 repre-
sents braces extending from the rear to the front axles. 46 represents the brake lever
which has the usual pawl 47 and rod 48 attached thereto. 49 represents the rack on
which the brake lever works. The rack being supported by suitable standards 5.
51 represents the brake shoes to which are connected the usual rod 52 and lever 53.
54 represents tanks which may be used for holding gas and water.
The operation is as follows:-
As the roller 16 revolves in the direction shown by arrows in Figures II and VI, it
will be seen that when (by the use of the lever 27) the friction roller 18 is pressed
into contact with said roller, it will cause the friction roller to revolve in the direction
shown by the arrows, and as the friction roller also comes in contact with the roller 17
on the axle of the car, it will cause the roller 17 to turn in the direction shown by the
arrows at the top of said wheel, and thus drive the car in a forward direction.
When it is desired to travel in the opposite direction or reverse the motion of the car,
all that is necessary to do, is to so manipulate the lever that the friction roller 18 will
be raised out of contact with the rollers 16, 17, and the friction rollers 38, 39, raised
into contact with said rollers. It will be seen that the roller 16 would cause the
friction rollers 38, 39 to turn in the direction shown by the arrows, which would ause
the roller 17 to turn in the direction shown by arrows on the lower side of the same.
which would cause the car to travel in the opposite or backward direction. There is
sufficient space between the friction roller 18 and the friction rollers 38, 39, so that
by the proper working of the lever they may, at the same time, be all held out of
contact with the rollers 16, 17, when it is desired to stop the car.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. In a street car motor, the combination of the roller 16, and suitable means for
turning the same, a roller 17 secured to one of the main axles of the car, a friction
roller 18 as a connecting medium between the rollers 16, 17, crank 23, and lever 27
for holding said friction roller in or out of contact with said rollers 16, 17, substantially
as described and for the purpose set forth.
2. In a street car motor, the combination of the rollers 16, 17, means for rotating
the roller 16, friction rollers 38, 39, means for holding said friction rollers in contact
with each other, and a crank 23 and lever 27 for holding said rollers in or out of
contact with the rollers 16, 17, substantially as described and for the purpose set forth.
3. In a street car motor the combination of the friction roller 18 secured to a
swinging bar as a connecting medium between two rollers for the purpose of driving
a car in a certain direction and friction rollers 38, 39, attached to a swinging bar as a
connecting medium between two rollers for the purpose of driving the car in the
opposite direction substantially as described and for the purpose set forth.
4. In a street car motor, the combination of the drive shaft 9, intermediate shaft 12,
means for rotating the shafts, roller 16, secured to shaft 12, a roller 17, secured to one
of the axles 18, friction roller 18, journaled to a swinging bar 19, friction rollers 38, 39,
journaled to a swinging bar 37, said bars 19, and 37, being pivoted to a crank 23,
and means for connecting said crank with an operating lever, substantially as
described and for the purpose set forth.
5. In a street car motor the combination of the plate 28, being supported by a
rod 29, and one of the axles 18, and suitable standards secured to said plate for the
purpose of supporting the friction rollers, and lever for operating the same, sub-
stantially as described and for the purpose set forth.
