Improvements in Motor Cycles.
I, CHARLES THOMAS BROCK SANGSTER, Director and Works Manager to The
Cycle Components Manufacturing Company Limited, of Bournbrook, near the
City of Birmingham, do hereby declare the nature of this invention to be as
follows:
This invention relates to motor cycles, principally tricycles, driven by oil,
vapour or other portable engines carried upon or supported by the framing of
the vehicles, and particularly by oil motors of the "Young" type and consists in
the one part, in an improved construction of the framing; in another part, in an
improved arrangement of the motor so as to bring it within the frame; in a
third part, in placing the motor in an inclined position instead of upright as
heretofore, thereby reducing the jar or vibration; in a fourth part, in mounting
the cylinder or connecting it to the framing by expansion joints, instead of
coupling it to the crank-race by bolts; and in a fifth part in the disposition and
arrangement of the carburetter, whose lower part is made to constitute a chest for
tools. In carrying out one form of the improved vehicle, when applied to a
motor tricycle, the main framing is of a diamond or trussed beam figure, with a
lateral stay, constituting the seat pillar directed between the top and bottom
members. The forward ends of the front members are connected to the head or
sleeve, in which the steering column, terminated by the side forks of the front
wheel works, whilst their inner ends are connected respectively to the seat lug
and the bottom bracket, to which the opposite ends of the lateral stay or seat pillar
are respectively connected. The bottom bracket is provided with crank axle
foot-power cranks and chain wheel, for transmitting power by a drive chain to
the rear axle of the machine, independent of that transmitted by the motor. The
lower member of the framing in passing from the crank axle bracket to the axle,
describes a downward curve, and is fitted with inwardly disposed brackets, between
which the crank race of the motor is disposed, which race may be bolted to the
carburetter, which comes at the back of the seat member of the frame, and
An oil reservoir or tank may be arranged
between it and the curved bottom stay.

Improvements in Motor Cycles.
I, CHARLES THOMAS BROCK SANGSTER, Director and Works Manager to The
Cycle Components Manufacturing Company Limited, of Bournbrook, near the
City of Birmingham, 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:.
--
This invention relates to motor cycles, principally tricycles driven by oil;
vapour or other portable engines carried upon or supported by the framing of
the vehicle, and consists in the one part, in an improved construction of the
framing in another part, in an improved arrangement of the motor whereby the
whole of the parts of the same are brought within the frame; in a third part,
in placing the motor in an inclined position instead of upright as heretofore,
thereby reducing the jar or vibration; in a fourth part, in mounting the cylinder
or connecting it to the framing by joints, which admit of the expansion and con-
traction of the same instead of coupling it to the crank-race by lolts; and in a
fifth part in the disposition and arrangement of the carburetter, whose lower part
is made to constitute a chest or box for tools and other accessories.
Figure 1 of the accompanying drawings represents an elevation of a motor
tricycle embodying our improvements.
Figure 2 is a back end elevation of the same.
Figure 3 is a topside plan thereof.
Figure 4 is a view, upon an enlarged scale, showing the method of mounting
of the motor cylinder and the means employed for connecting it to the crank box
and the framing of the machine.
Figure 5 is an elevation of the upper part of Figure 1, but with a part in
section illustrating the connection of the cover of the cylinder by a special joint
admitting of the expansion of the metal through the heat generated by the
motor when working.
Figure 6 is a topside plan of Figure 5.
Figure 7 is an elevation of the connection bolt or pin employed in the said
expansion joint.
Figure 8 is an elevation of the carburetter or vapor generator, separately,
showing the tool chest provided in the lower part thereof.
Figure 9 is a like view of a part of the carburetter as Figure 8, but showing
the door to the tool chest part open.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
The framing of the vehicle consists of the front part a, comprising top and

page_text: bottom tubes a, a, head tube a³ and seat tube a*, the latter being directed
between a seat lug a5 (which grips the adjustable pillar b, for supporting the seat)
and the bottom bracket or auxiliary crank-axle bearing sleeve a, whilst the steer-
ing column c, passes through the head tube a, and is connected with the front
wheel forks d, which are preferably provided with supplementary stay
members d', d, to impart the required strength thereto.
The bottom bracket as, is provided with crank axle and foot-power cranks which
are connected on the application of driving power to the pedal to the chain wheel
indicated by e, through suitable clutch mechanism, which wheel then transmits
auxiliary force through the drive chain to the driven axle to assist in the starting
of the motor but when the motor is in operation the feet may remain stationary
upon the pedals, the clutch mechanism admitting of the chain wheel then running
free.
The rear portion of the framing consists of a pair of spread out back stays a",
proceeding in opposite directions obliquely from the seat pillar clip to opposite
end castings or junctions as, connecting together a pair of horizontally disposed
members a, a¹o, arranged across the back of the machine, parallel with one
another and with the driven axle g which has the back wheels g', made fast
respectively to its opposite ends and runs within bearings 92, suspended from the
said junction fittings as, and also from a further and similar fitting a", disposed
near to the middle of and connected to, the said crossing members a³, a¹. The
bottom member a¹², of the rear framing first passes at a downward inclination from
the back of the crank axle bracket as, and then describes an upward curve and
terminates beyond the axle g, in a junction socket or lug a¹³, formed integral with
or suspended from a fourth and centrally disposed junction fitting a, carried by
the members a, a10, and within the space comprehended by the seat tube a, back
stays a, parallel cross members or lateral stays a, and curved bottom tube a¹²,
the whole of the parts of the motor, together with the driven axle g, are included,
instead of the cylinder, crank box and cognate parts of the said motor being
arranged or suspended behind the driven axle and outside the frame as in motor
tricycles of this type heretofore constructed whereby the structure is rendered
much more rigid and compact and vibration is considerably reduced.
h is the cylinder of the motor, preferably disposed in an inclined position
relative to the crank box as represented in Figures 1 and 4 (thereby reducing the
jar or vibration when running) and bolted at its lower end h¹, to the said crank
box h2, which encloses the cranks, fly wheel and crank shaft h³, of the engine and
is suspended from and connected to the framing by a clip h, or similar device
encircling the bottom member a12, and also by being bolted to a pair of inwardly
disposed bracket arms a15, proceeding from the junction fittings a", a. The upper
end of the cylinder is provided with a cover h³, carrying the vapour admission and
exhaust valve chest h6, and is connected to the summit of the central fitting a
(which may be integrally formed with the socket a¹³, and bracket arm a¹5, as a
single solid casting) by means of a bolt i, passing through a sleeve a¹ on the said
fitting and having the head i¹, and its inner end of a dovetail section or with
inclined sides 22, (see Figures 6 and 7) adapted to take within a corresponding
shaped channel 10, with undercut edges h", formed in the cover h, and in the
longer direction of the cylinder, whilst the outer end 3, extending beyond the
sleeve is screwed to receive the clamping nut 4. This joint provides an efficient
connection of the upper part of the cylinder to the framing and yet admits of the
unimpeded expansion of the cylinder.
The end of the crank shaft h³ extends through the walls of the crank box and
is provided with a small motor pinion h8, gearing with and driving a large toothed
wheel, keyed to the driven axle of the machine, which said axle is also pro-
vided with a small toothed or cog wheel j, over or around which the drive chain
of the auxiliary foot-driving gear passes.
Also included within the space comprehended by the members of the back part
of the framing, but forward of the motor, is the carburetter or vaporiser k, which

page_text: is attached by clips k¹, to the seat tube a*, and may also be bolted, if required to
the crank box. This carburetter is generally of the ordinary construction and
the vapour generated thereby is fed to the valve chest of the motor through the
pipe, the supply being governed by a vapour regulating device k³, (of the
ordinary or any special construction), in connection with the said pipe, controlled
by a system of levers k, k, and connecting rod 6, with the last named lever being
fulcrumed to the top tube a¹, of the frame in position convenient for being
manipulated by the driver. The exhaust pipe, leads from the exhaust valve
of the motor back into a heating coil or worm or equivalent device located within
the carburetter and within the petrol or volatile oil contained therein for assisting
in the generating of the vapour.
The bottom parts, of the carburetter is partitioned off from the upper generat-
ing part and the space 9, constitutes a chest or receptacle for tools and other
accessories and is closed by a door 10, hinged at one end and provided with a
suitable fastening.
The electric battery and induction coil for providing the ignition spark for
exploding the cylinder charge are enclosed within a box m, suspended by clips m¹ or
otherwise from the fore part of the machine. A suitable contact device for
completing the circuit when the charge is to be fired is also provided, together
if necessary with an exhaust silencer and other accessories usually employed in
connection with motor cycles of this type.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
_
First In the framings of motor tricycles, the special construction of the rear
part comprising the curved bottom member such as a, and lateral cross members
such as a, a¹o, with back stays such as a', whereby the whole of the working
parts of the motor are included within the frame or between the driven axle and
the seat tube, substantially as described and set forth.
Secondly In motor cycles, the combination with a framing of the construction
referred to in the preceding claim, of a motor in which the cylinder or cylinders
is or are disposed in an inclined position relative to the crank axle, whereby
jarring or vibration is reduced, substantially as described and set forth.
Thirdly: In motor tricycles, connecting the cylinder to the framing by a joint
or joints that will admit of the expansion and contraction of the metal when the
motor is in operation, substantially as herein desered and set forth, instead of
securing the said cylinder only to the crank box by means of bolts.
Fourthly: In motor tricycles, connecting th. cylinder or a part of the same,
to the framing by means of one or more bolts passing through a sleeve or
equivalent on the said framing, with the head, which is of a dovetail or like
section, taking into a corresponding recess the cylinder, whilst the screwed end
receives a clamping nut, substantially as and for the purpose described and set
forthi.
:
Fifthly In motor tricycles, the general construction, arrangement and com-
bination of the motor and its cognate parts, and the means of connecting and sup-
porting the same to and from the framing, substantially as described and set forth.
