Improvements in and connected with Dynamos and the Driving of
same and Electric Motors for the Driving of Vehicles and
Machinery.
1, JOHN VAUGHAN-SHERRIN, of 3 Codrington Villas, Ramsgate, in the County
of Kent, Electrical Engineer, do hereby declare the nature of this invention to be
as follows:-
According to this invention I so arrange the armaturo and the field magnets as
to rotate in opposite directions at the same or at different speeds while both actuate
the dynamo driving shaft or the motor shaft and by means of suitable gearing
I am enabled to suit the speed of rotation of the said shaft to the requirements of
the dynamo or the machine to be driven, whether for instance such machine be a
bath chair, or tricycle or a lathe, sowing machine, crane or any other machine.
For what I call a slow electric motor applicable for instance to a bath chair
I fix the field magnets on the wheel axle which in this case forms the motor shaft
and I fix the arinature on a sleeve or bosses free to rotate on the motor axle.
Between the two I arrange wheel gearing to differentiate the speed of the two and
allowing the motor shaft or vehicle axle to run sensibly slower than the armature.
The current is supplied from primary or secondary batteries on the vehicle, the
motor axle being provided with a disc of insulating material with two or more
metal bands and the brushes are attached to an outer case or support of insulating
material. The motor is enclosed in a casing.
For an electric launch I attach the propeller blades or paddles to the outside of
an enclosing casing, so as to form a screw propeller or a paddle wheel.
For driving lathes or other stationary machinery 1 mount the motor shaft in
bearings on a bed plate or standard.
For driving a dynamo at a suitably high speed by means of a steam engine or
other prime mover or driver 1 fix the armature on a sleeve or bosses free to rotate
on the engine shaft and fix the field magnets on the said shaft and provide genring
between the two.
The goaring may be toothed goaring partly or wholly made with teeth of
vulcanite, ebonite or the like. By means of change gearing two or more speeds may
be obtained.
Dated this 18th day of October 1895.

Improvements in and connected with Electric Motors for the
Driving of Vehicles and Machinery.
I, John Vaughan-SHERRIN of 3 Codrington Villas, Ramsgate, in the County
of Kent, Electrical Engineer, 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 :—
According to this invention the armature and the field magnets rotate in opposite
directions at the same or at different speeds, while both hang on and actuate the
motor shaft, and by means of suitable gearing the speed of rotation of the said
shaft is suited to the requirements of the machine to be driven, whether, for
instance, such machine be a road carriage, a tricycle, or a latho, sewing machino,
crane, or any other machine.
For what may be called a slow-driving electric motor, shown in the sectional
view Figure 1, and applicable, for instance, to a road or other carriage, the field
magnets A are fixed on the wheel axle B, which in this case forms the motor shaft,
and the armature C is fixed on a sleeve D or bosses free to rotate on the motor
axle. Between the two is arranged wheel gearing to differentiate the speed of
the two and to allow the motor shaft or vehicle axle to run sensibly slower than
the armature. The drum K, which is keyed to the shaft B and carries the field
magnets, has an internal tooth-wheel rim K', which gears with the two tooth-
wheels 1, that work loose on gudgeons G G', fixed to arme H* extending from a
sleeve H, which latter is fixed to one of the bearings I, for instance, by set screws I'
as shown. The wheels L gear with a pinion M, mounted on the shaft B and
carrying a tooth wheel N, which gears with a pinion O, mounted on the gudgeon G,
and carrying a tooth-wheel F, which gears with a pinion E that is fixed on the
sleeve D, which carries the armature C and runs loose on the shaft B.
current is supplied from primary or secondary batteries on the vehicle, the motor
axle being provided with a dizo of insulating material with two or more metal
bands, and the brushes are attached to an outer case or support of insulating
material. The motor is enclosed in a casing P, which in some cases forms the boss
or Dave of the wheel.
The
In Figure 2 is shown a simpler arrangement of gearing. The tooth-wheel K' is
keyed to the axle B, and the tooth-wheel H' is fixed on or in one with the sleave H,
which is kept from rotating by a set screw 1' as in Figure 1, or by any other
suitable menus.
Into the wheels Hand K' gear the pinions L and F, which run
free on the spindle G that is mounted at one end in one of the arms D! extending
from the sleeve D, and at the other and mounted in one of the arms D', the
boss of which runs clear of the sleeve H. The pinions LF thus roll upon the
wheels H' K'. If, as an example, the wheel K' has 30 teeth and the wheel H¹
has 32 teeth, then the shaft B will run 16 times slower than the armature C.
Similar pinions are by preference mounted in opposite arms D' D' as shown.
In Figure 3 is shown an equivalent aprucket-wheel and alain arrangement. On
the shaft B is fixed a tooth-wheel K', which gears with a piniou L on a spindle G³,
which latter has its bearings in an arm Hon the sleeve H and in one of the
arms D'. On the spindle G is fixed a sprocket-wheel N, which by chain is
connected to the sprocket-wheel O. On the spindle of the latter is fixed a
sprocket-wheel F, which hy chain is connected to the sprocket-wheel E that is
fixed on the sleeve D.
Figure 4 shows another form in which the gearing is duplicated, the connection
from the field magnet A to the shaft B being made by the gearing on the left-
hand side, and the connection from the armaturo C to the shaft B being made by
