PROVISIONAL SPECIFICATION.
Improvements in or relating to Motor-wheels and their Attachment
to Vehicles.
I, HENRY JOHN LAWSON, of 40, Holborn Viaduct, in the County of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide motor vehicles with motors combined
with the wheels in order to form a simple, cheap and compact construction of
vehicle. I shall refer to my device hereinafter as a motor wheel, because each
driving wheel with its supports carries its own motor and all the necessary
accessory parts.
Each motor wheel thus represents a complete driving arrangement and one or
any number of such wheels might be applied to a vehicle for driving purposes.
Another point of considerable importance in my invention is that besides the
compact and simple construction of my motor wheel, its various parts are so
disposed as to balance one another and thus avoid the awkward unsteadiness
common with many types of motor vehicles.
In carrying out my invention with one motor only, I mount the motor on one
side of the road wheel, and pass the shaft through the centre of the hub of the
wheel. The motor shaft is made to project beyond the hub of the wheel on that
side furthest from the motor, and a fly-wheel is mounted upon it which acts as a
counter-balance to the motor.
وو
"Crypto' or similar gear is arranged between the motor shaft and the hub
of the road wheel and the gear is enclosed in a case which may also be used to
secure the motor to the framing by which the road wheel is supported. The
motor might be further secured to the said framing by one or more brackets.
If preferred the gearing may be arranged to give two or more speeds, the
different speeds being brought into operation by means of band brakes, which
when tightened upon their respective drums hold certain portions of the gear
stationary, whilst other portions are allowed to revolve. Thus the driving shaft
may actuate a central wheel which upon each side of it carries a driving cog-
wheel. These cog-wheels being of different diameters effect different speeds when
one or the other is in operation. A vertical motor is preferably used having a
plain cylinder provided with air cooling devices, the inlet valve being so arranged
that it can be immediately freed in case of its sticking by means of congealed
oil, or other obstacle, the exhaust valve may be operated by a rod and suitable cam
geared down.
The crank case is so constructed that it forms an oil reservoir.
for the crank pin and is also arranged to lubricate the valve gear and piston.
The fly-wheel is preferably not enclosed, but a large disc properly balanced
forms the crank and revolves in the oil, thus enabling a small and compact crank
chamber to be used.
The carburettor may be arranged above the motor wheel and enclosed in a tank.
which may be provided with several compartments for containing lubricating oil,.
or oil for the burner if tube ignition is used, or batteries may be enclosed in the
same if electric ignition is used. When tube ignition is used, the compartment

page_text: containing the oil for the same may be provided with a pump in order that a
certain amount of pressure may be maintained upon the surface of the oil by
compressing air into the chamber.
To start the motor a mechanism is provided which may comprise a pawl and
ratchet arrangement operated by a cord, the cord being returned by means of a
spring, or a simple bevel gearing operated by a suitable handle may be used.
Upon the carburetted tank are arranged levers for regulating the amount of
air admitted to the carburettor and for regulating the amount of carburetted air
supplied to the motor.
The steering handles may be provided with some arrangement for absorbing
vibration and the usual-form of lever is provided by which a band or other brake
may be applied to the gearing to change the speed and a similar lever may be
used to regulate the mixture, put on the brake to any other wheels and at the
same time to lift the exhaust valve.
The motor wheel arranged as above described is specially adapted for use as a
front or steering wheel of a bicycle, tricycle or like vehicle, but may also be
used as a rear driving wheel, for say a three-wheel vehicle. In this case the
framing of the vehicle may be made of angle or channel steel bent in the form of
an elongated U, the bent end of the U or fork thus formed being turned outwards
to provide members upon which the front or steering wheels may be mounted.
The motor wheel may be mounted within the bent or closed end of the U shaped
frame, and suitable supports may be built up upon this frame to carry the
necessary seat or seats and steering apparatus.
The same kind of frame may be used for a bicycle or if preferred a straight
single bar instead having the fittings mounted upon it.
In some cases I prefer to so situate the motor that it may drive an internally
Soothed wheel arranged within the road wheel or I may drive by means of other
forms of gear than the Crypto system such as are used in ordinary lathes but
always using my fly-wheel as a counter-balance.

Improvements in or relating to Motor-wheels and their Attachmert
to Vehicles.
I, HENRY JOHN LAWSON, Engineer, of 40, Holborn Viaduct, in the City of
London, 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 of this invention is to construct a wheel with a motor and driving
gear attached which may be readily applied to any existing cycle-fork with as
little alteration to the fork as possible, thus enabling the owner of a cycle to
convert his machine into a motor cycle at a comparatively small cost. This
complete driving device will hereinafter be referred to as the motor wheel.
Although the above is the principal object of this invention the same form of
motor-wheel may be made more heavily, to suit other vehicles besides cycles.
The principal features of this invention are that the wheel hereinafter called
the driving or road wheel is provided with a hollow axle or hub free to revolve in
•

page_text: ball bearings formed one at each end of the hub in a lug adapted for attachment
to the blade of a cycle-fork. A motor is arranged on one side of the wheel and
the motor shaft passing through the hollow hub of the wheel and extending
beyond the further side of the same is provided with a fly-wheel which acts as a
counterpoise to the motor. The motor shaft is connected to and drives the road
wheel by means of a simple form of speed reducing gear.
The invention has further reference to details connected with motor vehicles or
cycles formed by the application of a motor wheel to an ordinary cycle or
vehicle, or to the adaptation of different vehicles to receive a motor-wheel.
The invention will be clearly understood by reference to the accompanying
drawings in which
Figure 1 is a central vertical section through a motor wheel constructed accord-
ing to this invention and shows one method of attachment to the front fork of a
cycle;
Figure 2 is a section of the same on the line 2-2 of Figure 1;
Figure 3 is a perspective view showing one method of applying the motor
wheel to a tricycle;
Figure 4 is a perspective view showing another method of doing the same;
Figure is a central vertical section of the driving and starting mechanism
shown in Figure 4;
Figure 6 shows the application of a motor wheel as the rear-wheel of a bicycle;
Figure 7 is a longitudinal section through the carburettor tank; and
Figure 8 is a detail of construction.
Like letters indicate like parts throughout the drawings.
The road or driving wheel A of the motor-wheel illustrated in Figures 1 and 2
is constructed after the manner of an ordinary cycle wheel and made sufficiently
stout to withstand the additional wear and tear caused by its motor. Its hub A¹
is made hollow throughout. A motor B is arranged on one side of the wheel A
and the motor shaft B is passed through the hub A¹ and provided on the other
side of the wheel A with a fly-wheel C which acts as a counterpoise to the weight
of the motor B. The ends of the hub A' are provided with ball bearings A2 formed
in lugs A adapted to be bolted to the blades of a cycle fork. Each of the lugs A³
is split, preferably at its base, and provided with projections A through which is
passed a bolt A³ (Figure 8). By screwing up the bolt A the sides of the lug are
tightened on the cups A of the bearing and thus prevent their displacement
when once adjusted.
The motor-shaft B is driven direct, from the piston rod 132 of the motor B by
means of a crank dise B and pin B arranged within the crank chamber 135 of
the motor, but drives the hub A¹ and consequently the driving or road wheel A
through the medium of reducing gear D. The reducing gear 1) comprises a
pinion preferably cut on the shaft B and which engages with two wheels 12
mounted on an arm 13, each wheel D² being free to turn upon its stud or
pivot D by which it is secured to the arm 13. The arm D3 is provided with an
extension or sleeve 15 which acts as a bearing surface for the shaft B¹ and to
which the hub A is fixed in any convenient manner. An annular internally.
toothed wheel 10 is secured to one of the lugs A3 and surrounds and engages with
the wheels D2. When in operation this wheel De acts as a fixed point of bearing'
for the wheels 12 as hereinafter described. The whole of the gear, which, as
may be clearly seen from the drawings (Figures 1 and 2) lies within the outer
annular wheel D, is completely covered in by a plate 1 held in position over the
open side of the annular wheel 16 by means of bolts 18 which pass through the
plate and secure it to lugs D³, with which the wheel D is provided.
The combustible mixture is supplied to the cylinder by a pipe B and enters
through a suction valve B. The charge is ignited by the tube 138 rendered
incandescent by a burner in the well known manner, or electric ignition may be
used. The exhaust gases pass out by the exhaust valve B through the pipe Bo
and silencer B. The exhaust valve is operated by a cam B1 geared to the motor

page_text: .
shaft B¹ by pinions B13. The crank chamber B³ of the motor is provided with a
circular flanged projection B by which it is secured to the plate 1 of the annular
wheel D. This circular flanged projection is cut away at the lower side for the
sake of lightness. A sleeve or hollow extension B15 is secured to or cast on the
crank chamber B³ and forms a bearing for the end of the motor-shaft B¹.
From the above description it will be seen that in applying the motor wheel
to an ordinary cycle-fork it is only necessary to secure the lugs A³ to the blades
of the fork when all the parts will be held in place. This may be done by
cutting off the ends of the blades as at E and brazing in lugs such as E¹ to which
the lugs A³ may be bolted. By thus securing the lugs A3 all the other parts of the
motor-wheel are, as stated above, held in position but the motor may be further
secured if desired by means of a bracket such as E2 which may be used as a
stay between the upper part of the motor and the blade of the cycle fork.
The operation is as follows:-
、
The motor having been started causes the shaft B' and consequently the pinion D1
to rotate at a high speed. The wheels D2 by means of their engagement with the
pinion D are also made to revolve on their pivots 14 but owing to their engage-
ment with the fixed wheel 16 they are compelled to travel round the pinion Di
as they revolve carrying with them the arm D³ upon which they are mounted. As
has been described above the arm D3 is provided with an extension or sleeve D³
which carries the hub A' of the wheel A fast upon it and thus the wheel A is
caused to rotate in the same direction as the shaft B but at a reduced speed.
Figure 3 shows a motor wheel arranged as in Figures 1 and 2 applied as the
front wheel of a tricycle. The carburetted air, lubricating oil and fuel for the
burner for the ignition tube are supplied from a common carburettor tank F
supported above the wheel A from the cycle fork by a bracket not shown in the
drawing. The internal arrangement of the tank F is shown in Figure 7. The
tank is divided into three compartments F1 F2 13 by partitions FF. The
lubricating oil is carried in the compartment F and may be fed to the parts
needing lubrication by a pipe which may communicate with the cock F. The
carburettor is arranged in the compartment F2 and is of known construction
and in itself forms no part of the present invention. The carburettor is provided
with the usual plug valves F7 F8 for regulating the admission of air to the vapour
from the oil or spirit contained in the carburettor and the admission of the com-
bustible charge to the pipe B and thence to the motor respectively. The valve F8
is operated by the usual handle F9 (Figure 3) but the valve F is controlled by
a lever F which carries a threaded link F. The link F is received by a
correspondingly threaded sleeve 12 which is connected by a swivel joint to a
bracket fixed to the upper part of the carburettor. The sleeve F12 is provided
with an enlarged portion F1 by which it may easily be rotated so as to screw
more of the link u into or out of it according to the direction it is desired to
operate the valve. As this valve requires nice adjustment this arrangement for
its control is to be preferred to the usual handle as used for the valve F. The
oil for the burner is carried in the compartment F3 which is provided with the
usual force pump F16 by which a slight air pressure may be made to bear upon
the surface of the oil. The oil passes to the burner G by a pipe G¹ controlled by
a cock at the bottom of the tank F. The burner G is surrounded by a
suitable casing G2 which also encloses the ignition tube in the usual well-known
manner. A lever H is provided within easy reach of the rider and communicates
by means of a link H' and lever H2 with the exhaust valve 139. The lever H3 is
pivotted at H³ (Figure 2) and the opposite, end to that to whch the link H
is connected is bifurcated and engages with the valve rod or part which operates
the valve rod (Figure 1) so that by raising the lever H the exhaust-valve B is
immediately opened. A second lever H similarly arranged operates a band
brake on the rear axle of the tricycle in any well-known manner.
The operation of the motor-wheel has been already described. The tricycle
is provided with the ordinary pedal and crank driving mechanism and the motor

page_text: is started by pedalling the whole machine forwards. To render this less
laborious a cock I is provided at the top of the cylinder and when open 'permits
the ingress and egress of air to and from the cylinder and thus reduces the
suction of the piston. When the motor is started the cock I is
closed. A lever I arranged within easy reach of the rider at the
side of the carburettor tank F and connected by a connecting rod I2 to the
lever which controls the cock I permits the rider to open and close the said cock
whilst mounted. If preferred the cock I may be dispensed with and the exhaust
valve opened slightly by means of the lever H until the motor is started.
Figures 4 and 5 illustrate the application of the motor wheel as a rear driving
wheel of a tricycle. The general arrangement of the motor wheel is the same
as that described herein.
The hub A of the wheel A is in this case not mounted in ball bearings and
does not extend through the lugs A³ but is mounted free on the motor-shaft 131
and the lugs A3 are provided with plain bearings A in which the shaft B' runs.
The reducing gear D is placed between the lug A³ and the hub A¹ of the
wheel A and the lug A3 is enlarged to receive the flanged circular extension B
of the motor B which is thus bolted direct upon it.
To enable the motor to be started without imparting motion to the whole
tricycle the wheel 16 of the gear D is mounted free upon the outside of the
bearing A formed on the lug A3 to which the motor is attached and is provided
on its outer periphery with a band brake 10 by which it may at any time be held
stationary or allowed to run idle. The wheels 12 are mounted direct upon the
spoke flange of the wheel A, the flange being made sufficiently large for this
purpose, thus dispensing with the arm D. The gear D is shown in Figure 5
as arranged for three wheels 12; any number of wheels D2 may in fact be used
for this form of gear so that the pinion I¹ may be supported all round if desired.
On that side of the hub A' opposite to that upon which the gear D.is arranged
is mounted a sprocket wheel J which may be driven when required by the usual
chain and pedal mechanism with which the tricycle is provided. The sprocket J
is provided with an annular recess J! and is mounted free upon the extension A
of the lug A. The sprocket is thus free to turn in either direction and is indepen-
dent of the hub A and consequently the wheel A. Within the recess J¹ is
arranged the usual wellknown form of roller and cam friction clutch having
rollers J2 and a cam J3 which is fast upon the motor shaft B¹.
The operation of this starting mechanism is as follows:-Presuming it is
desired to start the motor without moving the whole tricycle the rider slacks
the band-brake D10 and pedals forward as if to propel the tricycle. When
pedalling in this direction the sprocket J engages the cam J3 by means of the
rollers J and causes the motor shaft B to which the cam is keyed or otherwise
secured to revolve. The motor B will thus be started, but no motion will be
imparted to the road wheel A as the pinion D' of the connecting gear D although
revolving only causes the wheels 12 to revolve and drive round the wheel D. The
moment however the band-brake D10 is tightened so that the wheel D is held
stationary the wheels. Da will commence to travel round the pinion D¹ as before
described thus causing the hub A¹ upon which they are carried to revolve..
If preferred the band-brake Do need not be slackened for starting but the
motor may be started and the tricycle propelled forward at the same time. It
will. be understood that as soon as the motor is started the pedals may be held
stationary and the friction clutch allowed to overrun.
The carburettor tank F is arranged above the wheel A as in the case in which
the motor-wheel is described as used for the front wheel of a tricycle, and is
supported from the rear fork of the machine by a bracket F18 The motor is in
this case provided with electric ignition device which however forms no part of
the present invention. The batteries for the ignition spark are enclosed in a
box or casing K: carried upon the framing of the tricycle and the sparking coil
is enclosed in the compartment. F³ of the carburettor tank F. The timing

page_text: device K¹ is arranged at the side of the motor B the timing cam being mounted
on the same shaft as that which carries the cam for operating the exhaust-
valve B of the motor B.
The band-brake 1010 is operated by a handle " within easy reach of one of the
riders. The handle I is threaded and receives a spindle D¹² correspondingly
threaded. The spindle D¹³ passes freely through a lug D³ secured to the frame
of the machine. An arm 114 hinged or pivotted to the frame at D is provided
with a jaw which receives the end of the spindle D2 and is hinged to it by
a pin 17 passed through the jaw D and spindle D2. The spindle D is thus
thus prevented from turning when the handle D is revolved but is connected to
the lever by a hinge joint. A wire D18 attached at one end to the end of the
spindle 12, or to the jaw end of the lever 1, is connected at its
other end to a lever 1019 to which both ends of the band-brake 1010 are attached.
The lever D is pivotted to a lug on the frame at D20 and one end of the band-
brake 10 is connected to the lever 119 on one side of the pivot D20 and the
other end is connected at 121 to that portion of the lever which projects beyond
the pivot 120.
The operation of the band-brake is effected as follows:-When the handle 1"
is rotated in one direction the spindle D is drawn up through it by means of its
thread and thus raises the end of the lever D1 and puts a tension on the wire D18.
The lower end of the lever 1019 is thus drawn upwards together with the end of the
band-brake 10 attached on that side of the pivot D20, but the other end of the
lever 119 is at the same time depressed and draws down the end of the band-
brake 10 attached at D21 so that the band-brake is by this means tightened from
both ends. When the handle D is revolved in the opposite sense, the spindle D12
and end of the lever D are lowered, thus slackening the wire 118 which then
permits the band-brake 10 to fall loose.
The control of the valve F8 by which the amount of carburetted air admitted to
the pipe B and thence to the cylinder of the motor B is regulated, is brought
within reach of one of the riders of the tricycle by a handle F arranged conven-
iently in front of one of the seats and having a detent 120 and rack whereby
it may be retained in any position in which it may be placed. The handle F19 is
.conveniently connected by a connecting rod F12 a bell-crank lever F2 and a
second connecting rod F to the lever I by which the valve F8 is operated. A
handle K is also arranged within easy reach of one of the riders for completing or
breaking the electric circuit from the batteries K to the electric ignition device,
when desired.
The lever H for operating the exhaust is connected to the lever H² (Figure 2)
by a wire H not shown in Figure 4. The lever H2 is for this purpose modified
and formed as a bell crank lever, as indicated by the dotted portion H³ having
the wire H attached shown in Figure 2. The exhaust valve 139 is opened by
raising the lever H which pulling on the wire H raises the forked end of the
lever H2. When the lever H is released the valve closes by means of its spring
and brings the lever H back into its normal position. The wire Ho may be
carried along the framing from the lever H to the lever H³ in any convenient
manner as, for instance, is hereinafter described with reference to Figure 6.
Figure 6 illustrates the application of a motor-wheel as the rear wheel of a
bicycle. With the exception of one or two slight modifications the various parts
are arranged as in the tricycle illustrated in Figure 4. The carburettor tank F,
which is larger than that shown in Figure 4, is carried by an additional piece of
framing L L built up on the rear fork of the machine, and is secured to the
same by the bracket 18 and one or more ties L'. If preferred however the
carburettor tank F may be made smaller and arranged as in the rear driving
tricycle described above. The band-brake D10 and exhaust valve B are operated
as described with reference to the rear driving tricycle one or two additional
pulleys and bell cranks being provided to guide the operating wires. The
handle D for operating the band-brake is arranged at the head of the machine.

page_text: The wire D₁ from the lever D14 is passed over a pulley at D2 and over a second
pulley at D23 to the lever D19.
The handle F for operating the carburetted mixture valve is also mounted
at the head of the machine. The bell crank F operated by the lever F is con-
nected to the link Fe (which operates the lever F for the purpose described
above) by means of two additional links and bell cranks. Fes F and F27 F28
respectively.
The link H and handle H for operating the exhaust-valve are arranged as an
ordinary plunger brake, the shoe or other brake mechanism being attached to the
end of the link. The link H¹ is provided with a projection H which engages a
bell-crank H pivotted at H to the frame of the machine. A wire H⁰ connects the
bell-crank H to a lever H" pivoted at H2 and to the lever H" one end of the
wire He is attached the other end of which is as already described secured to
the end H of the valve operating lever H. The link H' may be adjusted as is
usual with ordinary plunger brakes so that by proper adjustment the lever H
may be made to open the exhaust-valve 19 only, when slightly raised, but when
fully raised may be arranged to apply any well-known form of tyre or rim-brake.
The cock I may he operated by the rider reaching slightly behind the saddle
or it may be connected by suitable links and cranks to a handle arranged in front
of the handle-bars or head of the machine.
If preferred, the gear D with its band-brake D10, may be arranged outside the
fork between the motor B and the lug A3, in a similar manner to the arrange-
ment shown in Figures 1, 2 and 3, provision being however made for the wheel 1)
to revolve when the band-brake is slack.
It will be understood that the various connections between the operating handles
and valve or other parts operated by such handles in any of the devices described
may be variously arranged to suit the requirements of different riders or different
forms of machines to which it may be desired to apply the motor-wheel, for
instance, a single operating lever may be connected with the valve which controls
the admission of oil to the cylinder, the band-brake and the exhaust
valve of the cylinder in such a manner that when the lever is
moved in one direction the oil supply is cut off and the band-brake applied (either
simultaneously or by a further movement of the lever in the same direction) and
when the lever is moved still further in the same direction the exhaust valve
opened. In some cases the exhaust valve may be arranged to open when the
operating lever is moved in the opposite direction to that by which the oil supply
is cut off and the brake applied.
The motor-wheel may be applied as the front wheel of a bicycle and arranged
as in the front-driving tricycle described with reference to Figure 3 and the
frame may be either in the form of a lady's or gentleman's machine. The rear-
driving tricycle too need not be of the " Olympia" pattern and may be adapted
to carry one or any other number of persons within reasonable limits.
Any of the above arrangements may be also provided with more than one
set of speed-gear if desired so that different speed may be obtained by tightening
the band-brake on the set of gear required and slackening that or those, on the
set or sets, not required.
.
The different sets of gear may be arranged side by side or one or more on one
side of the wheel and ditto on the other as found convenient.
As it is found that the sudden application of the brake-band 1) 10 to the gear
wheel D often, throws the driving gear in so suddenly as to stop the motor, a
device may be applied for tightening the band-brake which prevents the same
being brought suddenly upon the wheel D6. To effect this each end of the band-
brake may be carried through a lug or nut and held in place by a spring one
end of which bears against a head on the brake-band, and the other against the
lug. The ends of the band are free to slide in the lugs, and these latter are
carried upon a right and left hand screw-threaded shaft. By this means when
the screw-threaded shaft is revolved in one direction the two nuts or lugs are

page_text: brought together, thus contracting the band-brake upon its drum, the springs
at the ends of the band-brake during this operation being compressed. The
springs in this manner prevent the sudden application of the band-brake in full,
as it cannot be made to bear with great pressure upon the brake drum or
wheel De until the springs have been separately compressed. It will be seen that
the moment the springs are completely compressed, they practically act as a stop
through the medium of which the full force of the band brake may be applied.
The pressure which the springs exert may be regulated by providing the ends of
the brake-band with adjustable nuts. Any convenient mechanism may be provided
for operating the screw shaft, or the nuts or lugs may be made to slide upon
shaft, their movements being controlled by a wire and operating lever similar
to that shown at 1" (Figure 6), the lever for such operating mechanism always
being within easy reach of the rider when mounted upon the vehicle.
In order that the bearings of the wheels D2 in the speed gears may be readily
oiled without dismounting any part of the mechanism, a passage may be made
through the casing, with which they are surrounded, communicating with a
longitudinal groove in the spindle D so that oil may be admitted to the centre of
the wheel boss.

invention and in what manner the same is to be performed, I declare that what
I claim is:-
