PROVISIONAL SPECIFICATION.
Improvements in the Mode of Driving Electrical Vehicles.
1, ALFRED DICKINSON of Tramway Depot Darlaston in the County of Stafford
Tramway Manager do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object improvements in the mode of driving electrical
vehicles by which I am enabled to carry the whole of the gearing in pitch line and
independent of the frame which carries the car body.
The gear is all mounted in an extra frame one end of which is pivoted upon one of
the bogie axles and the other end is so mounted in a radial axle box or horn plates that
this end of the frame is free to move upwards and downwards but its liberty is
governed by spring arranged to check its movement within certain defined limits.
The central bearing of this moving end of the frame is circled so as to permit each of
the two rail wheels to nove unevenly without interferance with the frame.
My new arrangement of helical gear in this frame is as follows-I mount the motor
shaft near the centre in suitable bearings, and transmit the motion through helical
gear and counter shafts to the bogie axle on each side.
The intermediate or counter shafts being also mounted in the said frame.
I thus get the magnets the armatures the countershafts and all the gearing except
the helical wheels on the bogie axles in the one frame by which means I am enabled
to use helical gearing which together with the frame is thus iu sensitive elastic working
connection with the bogie axles.

COMPLETE SPECIFICATION.
Improvements in the Mode of Driving Electrical Vehicles.
I, ALFRED DICKINSON of Tramway Depot Darlaston in the County of Stafford
Tramway Manager do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention has for its object improvements in the mode of driving electrical
vehicles by which I am enabled to carry the whole of the gearing in pitch line and
practically independent of the frame which carries the car body.
The gear is all mounted in an extra frame one end of which is pivotted upon one of
the bogie axles and the other end is so mounted in a radial axle box on horn plates or
its equivalent mechanism that this end of the frame is free to move upwards &
downwards but its liberty is governed by springs arranged to check its movement
within certain defined limits. The central bearing of this moving end of the frame is
circled so as to permit each of the two rail wheels to move unevenly without interference
with the frame. My new arrangement of helical gear in this frame is as follows. I
mount the motion shaft near the centre in suitable bearings and transmit the motion
through helical gear and counter shafts to the bogie axle on each side the intermediate
or counter shafts being also mounted in the said frame.
I thus get the magnets the armatures, the counter shafts and all the gearing except
the helical wheels on the bogie axles in the one frame by which means I am enabled
to use helical gearing which together with the frame is thus in sensitive elastic
working connection with the bogie axles.
In order that my invention may be clearly understood and more easily carried
:

page_text: into practice I have appended hereunto two double sized sheets of drawings upon
which I have illustrated my invention applied to the bogie of an ordinary tramcar
and from which its application to other vehicles will be readily understood.
Figure 1 is a plan of a bogie having my frame attached thereto and shewing the
helical gearing in section.
Figure 2 is a longitudinal sectional elevation through the bogie the gearing being
removed so as to show the frame more clearly.
Figure 3 is a longitudinal section of the bearing of the moveable end of the frame
shewing the circling.
In carrying my invention into effect I provide the extra frame A one end of which
is hung or pivotted at A' upon the bogie axle B the opposite or other end of the
frame A being provided with the radial axle box 62 and or horn plates A² which are
mounted upon the bogie axle B₁ by means of the radial axle box 63 being made to
slide in the horn plates A³ thereby allowing the said horn plates A' to rise or fall as
the case may be. The liberty of the horn plates A2 in rising or falling is governed by
the springs D and D¹ which check and control the movement of the end A² of the
frame A within certain defined limits. The bearing 63 of this end of the frame is
circled as shewn at Figure 3 so as to allow each of the two rail wheels E and E' to
move unevenly without materially affecting the frame and also to allow the
wheels E and E³ to move unevenly, in the latter case the frame A taking its
inclination with the axle B, the circling of the bearing 63 allowing this to take place.
Having provided the frame A my new arrangement of helical gearing is as
follows: Imount the motor shaft F in or near the centre of the frame A in the
bearings a³ and a' and transmit the motion to the axles B and B¹ on each side by the
helical gear F and F to the counter shafts F³ which are also mounted in the frame A
by the bearings a³ and a and from the counter shafts, F³ by the helical wheels F*
and F to the axles B and B¹.
I thus get the magnets H armature J counter shafts F3 and all the helical gearing F1 F2
and F and F excepting the helical wheels F on the one frame A by which means I
am enabled to use helical gearing which together with the frame A is thus in sensitive
elastic working connection with both the bogie axles B & B¹.
Instead of circling the bearing 62 as shewn in Figure 3 I may pivot it to an
independent sliding piece working in the horn plates A and the amount which it would
be allowed to revolve may be limited by stops, or the horn plates may be straight and
a sliding or equivalent joint used in connection with the bearing to compensate for
the circular line described by the movement of the frame A. It will also be evident
that any number of countershafts carrying helical gear may be used in the separate
frame A with a similar effect as the ordinary vibrations and general movement of the
car does not interfere with it.
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
claim is :-
1st. The improvements in the mode of driving electrical vehicles by which greater
steadiness is obtained substantially as and for the purpose set forth and shewn upon
the accompaning drawings.
2nd. In vehicles driven by electricity the extra frame A for carrying the mechanism
substantially as herein set forth and shewn upon the drawings.
3rd. In vehicles driven by electricity the use of helical gear mounted substantially
as herein set forth and as shewn upon the drawings.
