LOCOMOTIVES AND OTHER LOCOMOTIVES OR MOTIVE POWER ENGINES."
This Invention has for its object improvements in Tramway locomotives and
other locomotives or motive power Engines.
We construct a Tramway locomotive with a flexible bellows like gas holder
having sides of leather or other suitable material and which can be filled by
connection with the ordinary gas mains.
From this gas holder gas is supplied through ordinary regulating bags to a
double liorizontal cylinder gas engine.
In this Engine the pistons give motion to a crank shaft on which is a belt pulley
and an endless band passes from this pulley to a loose pulley upon the main or
driving axle. Upon the crank shaft there is also a toothed wheel driving another
like wheel on a countershaft on which also there is a belt pulley driving by a belt
another pulley loose on the main axle.
Between the pulleys on the main axle there is a double cone revolving with the
axle and capable of sliding along it upon a feather. A neck formed in the cone
is embraced by a fork which can be moved laterally by a screw and lever handle.
The cone forms part of a friction clutch and enters recesses in the loose pulleys so
that the pulley towards which the cone is moved becomes fast with the main axle
and movement is given to the wheels. Thus without interfering with the gas
ID 21

page_text: engine which runs continuously the locomotive can be started or stopped or
reversed.
The gas engine is provided with a governor in which a fan is driven from the
engine through inclined surfaces. The resistance of the air tends to cause the fan
to lag and to rise up the driving inclines whilst a spring operates in the opposite
direction, so that the fan takes up a position dependent on the greater or less
resistance of the air arising from a higher or lower velocity. The fan controls the
valve and admits just the amount of gas required to keep the engine running at
its standard speed, whether it be coupled with the main axle or otherwise and the
friction coupling allows the axle in starting gradually to gather speed from the
Engine.
On locomotive or portable engines which requiro to carry a large quantity of gas
fuel, we provide a gas holder in which it can be stored under pressure and we
provide pumps on the locomotive or portable engine to be worked by the gas
engine for the purpose of forcing the gas into the gas holder. From the pressure
gas holder the gas is drawn off for use into a bellows like holder like that already
described but of smaller dimensions and the valve between the two holders is
opened by the collapse of the bellows like holder and closed as it becomes inflated
The gas in expanding cools the passages through which it passes and we cause the
water by which the cylinders are cooled to pass through contiguous passages,
thus heat is restored to the gas and the water rendered more efficient-for-cooling.-

JOSEPH QUICK and JOSEPH QUICK the younger both of 29 Great George Street
in the City of Westminster Civil Engineers "IMPROVEMENTS IN TRAMWAY
LOCOMOTIVES AND OTHER LOCOMOTIVES OR MOTIVE POWER ENGINES"
This Invention has for its object improvements in tramway locomotives and
other locomotives or motive power engines.
We construct a tramway locomotive with a flexible bellows like gas-holder
having sides of leather or other suitable material and which can be filled by
connection with the ordinary gas mains.
From this gas holder gas is supplied through ordinary regulating bags to a gas
engine having two or more cylinders.
T
In this engine the pistons give motion to a crank shaft on which is a belt pulley
and an endless band passes from this pulley to a loose pulley upon the main or
driving axle. Upon the crank shaft there is also a toothed wheel driving another
like wheel on a counter shaft on which also there is a belt pulley driving by a
belt another pulley loose on the main axle.
Between the pulleys on the main axle there is a double cone revolving with the
axle and capable of sliding along it upon a feather. A neck formed in the cone is
embraced by a fork which can be moved laterally by a screw and lever handle.
The cone forms part of a friction clutch and enters recesses in the loose pulleys so
that the pulley towards which the cone is moved becomes fast with the main axle
and movement is given to the wheels. Thus without interfering with the gas
engine which runs continuously, the locomotive can be started or stopped or
reversed.
The gas engine is provided with a governor in which a fan is driven from the
engine through inclined surfaces. The resistance of the air tends to cause the fan
to lag and to rise up the driving inclines, whilst a spring operates in the opposite
direction so that the fan takes up a position dependent on the greater or less
resistance of the air arising from a higher or lower velocity. The fan controls the
valve and admits just the amount of gas required to keep the engine running at its
standard speed whether it be coupled with the main axle or otherwise and the
friction coupling allows the axle in starting gradually to gather speed from the
engine.
On locomotive or portable engines which require to carry a large quantity of gas
fuel we provide a gas holder in which it can be stored under pressure and we
provide pumps on the locomotive or portable engine to be worked by the gas
engine for the purpose of forcing the gas into the gas holder. From the pressure
gas holder the gas is drawn off for use into a bellows like holder like that already
described but of smaller dimensions and the valve between the two holders is
opened by the collapse of the bellows like holder and closed as it becomes inflated.
The gas in expanding cools the passages through which it passes and we cause the
water by which the cylinders are cooled to pass through contiguous passages thus
restoring heat lost during compression and expanding the gas to its ordinary
working pressure.
In order that our said Invention may be most fully understood and readily
carried into effect we will proceed to describe the Drawings hereunto annexed,

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation and Figure 2 is an end elevation of a four wheeled
tramway locomotive constructed according to our Invention.
Figure 3 is a longitudinal section, Figure 4 is a transverse section and Figure 5
is a sectional plan of the same. Figure 6 shews separately a plan of the gas
engine with its governor.
The parts are indicated by reference letters as follows:-
A main gas pipe from reservoir to engines, B gas pipe from reservoir to side
lights. C water circulating pipes from tanks. D gas bag on supply pipe.
E reversing clutch. F reversing lever. GG pulleys loose on axle driven by L'L.
HH friction pulleys keyed to axle but having a lateral sliding movement in the
direction of G or G. I worm on reversing shaft. J gas reservoir. K brake
blocks worked by suitable brake gear, L L pulleys on main and secondary engine
shafts giving motion to G. G. M Silver's governor applied as governor of the
engine N slide to work valves. O cog wheels on main or secondary shafts of
engine. P gas inlet and cock to reservoir. Q, Q, water tanks. R axle, S S driving
wheels of car.
The method of action is as follows:-
The engines.being-made-to-revolve-in-a-given-direction-it-follows-that-one-of-the-
pulleys L L will revolve in the same direction and the other will revolve in an
opposite direction through the interposition of the cog wheels O O. Thus it will
be seen that the pulleys G G will be constantly revolving in opposite directions so
long as the motion of the engines continues.-Then by the action of the lever F
which moves the worm I on its shaft the clutch E throws the friction cones H H
into connection with either of the pulleys G G according to which ever way it (the
lever) is moved, and thus it will be seen that the motion of the pulley G is trans-
ferred to H and thus through the medium of the key and slot to the axle R which
being rigidly fastened to the wheels S S S S impels the car forward. If it is
desired to reverse the car, the lever F being thrown over forces the cones H into
contact with the opposite pulley; which revolving in a contrary, direction impels
the car in an opposite direction to the first.
Figure 7 is a side elevation of an eight wheeled tramway locomotive it is
provided with a reservoir for carrying gas in a compressed state. Figure 8 is an
end elevation and Figure 9 is a sectional plan of the same. Figures 10 give details
of some of the parts. In these Figures the several parts are marked with reference
letters as follows:-
A A A cylinders B B supply pipe from reservoir to engine, C regulator valve
chamber D pipe from reservoir to regulator valve E E regulator bellows
F regulator valve lever G G gas compressing pump H H supply pipe to pump I
delivery pipe from pump to reservoir J circulating pipe from tank to cylinder
K circulating pipe from cylinder to regulator valve chamber L circulating pipe
from valve chamber to tank. M reservoir of compressed gas N N governor lever
0 0 0 adjustment wheel P P spring R R R R R R slots in adjustment wheel.
The car is driven by the engine as in the four wheeled arrangement through the
medium of endless bands from the driving pulleys on engine to the driven pulleys
and friction cones on shaft of car wheels.
The admission of the gas to the engines is controlled in the first instance by the
bellows and regulating valves E and C and in the second instance by the revolving
governor as on 4 wheeled car, the adjustment of this governor being effected by the
wheel O which has slots R R &c, of different depths. This wheel by being turned
round until one or other of the slots is in a line with the lever N is held in that
position by the stop in the bar forming the frame of the governor and as the slots
are of different depth it is obvious that the pressure on the spring P will be varied
according to which slot is put into use and thus the action of the revolving fans

page_text: of the governor will be more or less impeded thus controlling the action of
engine.
The regulating valve is surrounded by the jacket C which is warmed by the
water which passes from the tank through the pipe J to the cylinder A then along
the pipe K to the jacket C and finally back to the tank through the pipe L.
The pump G is for refilling the reservoir M with compressed gas and is worked
by one of the driving pulleys or in some other suitable manner.
Having thus described the nature of our said Invention and the manner of
performing the same we would have it understood that we do not confine ourselves
to the exact details indicated by the Drawings but we claim :-
First. The combination substantially as herein described in a locomotive engine,
of a gas reservoir, gas engine, and frictional clutching arrangements, through
which to drive the wheels, such combination admitting of the gas engine being
maintained at a constant or nearly constant speed whether the locomotive be
running or at rest or starting or stopping.
Second. The combination substantially as herein described in a locomotive or
other motive power engine, of a high pressure gas reservoir, a gas engine, and
pumps to be worked by the said engine to charge the reservoir.
Third. The combination substantially as herein described in a locomotive or
other motive power engine, of a high pressure gas reservoir, a low pressure service
reservoir, a gas engine, and a water circulation withdrawing heat from the
cylinders and imparting it to the gas during expansion on passing out of the high
pressure reservoir.
Fourth. Our improvements in tramway locomotives and other locomotives or
other motive power engines substantially as herein described.
In witness whereof we the said Joseph Quick and Joseph Quick the younger
have hereunto set our hands and seals this Sixteenth day of June in the
year of our Lord One thousand eight hundred and eighty two.
