Improvements in or relating to Electric and other Motor Vehicles.
I, ROBERT COOKE SAYER, of 11 Clyde Road, Redland, Bristol, Civil 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:―
The object is to mount motors upon single bogie axles of cars, so that the motor
shall be carried every way upon springs independantly of the car springs.
The object is attained when the motor is rotary by the axle passing through
its centre and giving space for its play. When the motor is electric, by carrying
its interior, whether field magnets or armature upon friction balls supported by
its exterior, and both by the exterior being carried on springs supported by a
casing embracing them, which produced takes its bearings upon the axle and is
kept in place by the frame of the car. The weight of the car is carried by
bearings upon the same axle by a frame, which produced vertically forms the
logie pin and carries one end of the car by a frame suspended from the pin
by springs: so that the motor actuates the axle, and its wheels by arms that
allow the play of the springs; and the car is thrust either way by the bogie-pin,
and arms of the casing carrying friction wheels acting on the lower frame of the
car; so at the motor its axle wheels and casing may have a different horizontal
rotation to the car body, to pass round curves. That this may be adapted to
the known system of picking up the electric current from conductors in conduits,
one of the axle bearings carrying the car is produced and carries by a joint a
wheel upon which radials work, this wheel is inclined to and overlaps the car
wheel and has teeth that engage with those of one of the two series of teeth
usually provided in such rails, and as the car proceeds the wheel is rotated
and its radials enter rail slots and make contact with the electric conductors.
When the motor is an impulse engine the power is divided into two or more
grouped and balanced round the axle so that the impulses of pairs are given
together in reverse directions for each to neutralise the recoil of the other; space
is given in their connecting arms to allow the springs carrying the motors to
act; and the weight of the car is carried as above.

The Figs. 1 to 5 and 9 to 11 illustrate the object desired when adapted to
electric motors, which is also applicable to all rotary motors; and Figs. 6, 7
and 12 to electric motors deriving their power from conductors carried in conduits.
The Car 1 Figs. 1 to 5, is carried on any kind of rail or road by wheels 3 and 4
connected by the axle 5, that passes through the armature 6, Fig. 4, which is
carried on the field magnets 7 by the balls 8, Fig. 9, on the ring 208, adjustable
by screw bolts 308, and nut 408 running under fluid pressure within the cups 108;
and vertically and diagonally by springs 9 and 10 and 11, the ends at the
joints 12 being attached to the case of the magnets 7 and the ends of 10 at the
trunnioned nuts 13 upon the case 14 which is carried on the axle 5 by bearings 15;
the rod 16 passes through the springs, carries the nut 17, has a stop tube 18
forms the hinge 12 and passes through the nut 13; the magnets 7 are supported
laterally by the springs 19 acting against the central lug 20 attached to their
oase, Figs. 13 and 11 and their other end against the side lugs 21 of the
casing 14; the rods 22 pass through the springs carries a cup 23 in which friction
balls 24 work; other springs 19, Figs. 2 and 10 act similarly against the pro-
jection 25 of the casing 14 and side lugs 26 of the magnets 7. The axle 5
Figs. 2, 4 and 9 carries the arms 27, have spaces for the lugs 28 of the armature 6
and allow the springs to play. The car body 1 is carried on the axle 5 by
bearings 29 and 30 and frame 31, which produced forms the bogie pin 32 that
carries springs 33, from which the car 1 and its framing 36 is suspended by the
links 34 and frame 35; motion is given the cart by the pin 32, and arms 37
from the axle bearings 15 and wheels 38 acting against the segments 136 of the
frame 36.
When the electric current is obtained from a conduit the conductor 48 and 49
held in place by insulators 50 carried on the toothed rail 2 by supports 51; the
radial wheel 40 is inclined and carried from the bearing 30 close up to and over-
lapping the wheel 3 by arms 39, Fig. 12, and its joint 41; the teeth 42
engage with one line of teeth 43 of the rail 2, Fig. 8, and into which one series
of the teeth of the wheels 3 run.
A fixed channel 52 is carried on the bearings 53, and as the wheel 40 is
thrust round the lugs 54 of the radials 44 travel in it, and also in the slots 55
of the wheel 40, and projects the lateral tooth supports 45 and the radials 44 into
their slots 46 of the rail 2 between the screw bolt lugs 47, so that their ends
traverse the paths A or B, to make contact on either side of the conductors 48
and 49 by the closing spring action of their insulated sides; that they may be
withdrawn from the conductors 49 only or from 48 as well the lugs 54 are
caused to travel in the dotted paths 100 and 101 by the lower part of channel 152,
which is attached to the nut 56 of the screw bolt 57, Figs. 7 and 4, being actuated
by turning the handle 58, and directed by the lug 252 of the channel 152 tra-
versing the slotted arm 153 of the bearing 53; and for this purpose the sides 59
of the channel 52 is formed open at the bottom at 60, Fig. 7, to pass over the
upper fixed part of 52 as dotted at 352, Fig. 6, and the top of the lug 54 of the
radials 44 is thrust in teliscopically against a spring when it meets inclines,
not shown, formed in the roof of 52 so that they pass under the top part
of the sides 59 of 152 and through the lower open space 60; but when the
inclines are passed the spring thrusts the top part of the lug 54 out again to
be guided by the top part of the sides 59 of the channel 152.
The radials 44 have as usual electric contacts 61 to meet as they rotate, with
insulated contact pieces 62 and 63, Fig. 12, before the previous one has left it
or them, fixed on the bearing 53, and send current continuously from the con
ductors 48 or 49, 44, 62, 63 and line wire 64 to the motor.
The working is as follows:-
All motors rotary and reciprocating are balanced every way both when standing
and in motion on either side of a bogie axle 5, and when rotary it passes
through their centre, and when electric the armature 6 and field magnets 7

page_text: are provided with friction balls 8 to run on a ring 208 adjustable by balls 308
in fluid pressure admitted at 508 and passing out under a spring or weight
at 608 within the cups 108, to keep 6 and 7 equi-distant, the one to carry the
other and move together vertically, diagonally and laterally on springs 11, 10,
9, 10 and 19 supported by the case 14 carried on the axle 5 by bearings 15; so
that when the current passes from the conductors 48 and 49 up the radials 44
contacts 61, 62 and 63 to the motor, the lugs 28 of the armature acting against
the arms 27 to rotate them the axle 5 and wheels 3 and 4, the recoil of the
field magnets 7 is taken by light springs 11 and stiff ones 10 until they take
their bearing by the lugs 20 against the case 14 which reacts through the
arms 37 and wheels 38 against the frame 36 of the car; and vertical diagonal
and lateral oscillations of the motor are taken by the same springs, independantly
of the car body 1 whose weight is carried by the springs 33 of the bogie-pin 32
and by the bearings 29 and 30 of the axle 5.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed I declare that what I
claim is:-
Balancing motors when still and in motion round a single bogie-pin axle of a
car; carrying them vertically diagonally and laterally upon springs supported
by a casing or arms bearing upon a single bogie axle of a car and kept in position
by its frame; carrying a bogie-pin upon the same axle by bearings and frames
from which one end of the car is suspended on other springs by links; carrying
the armature or field magnets of dynamos on an adjustable ring by balls between
cups in fluid under pressure; a wheel carried diagonally and overlapping the
main wheel upon an hinged arm projecting from the axle bearing for teeth upon
it to engage with teeth in the rail and thereby receive motion and give motion
to electric conducting spring radials, whose spring lugs traverse slots in the wheel
and a channel formed of a fixed and an adjustable part with inner sides having
spaces to pass over the fixed part for the radials to be projected through slots in
or at the side of the rail and embrace electric conductors within a conduit.
Neutralising the recoil of connected impulse motors for them to be balanced
round a bogie axle and carried on springs. Enabling the single bogie pin axle
wheels and motor to have a different horizontal rotation to that of the car body,
substantially as described and shown on the drawings.
