PROVISIONAL SPECIFICATION.
A Rotary Gas or Oil Motor for Driving Tricycles or other Light
Vehicles.
We ARTHUR MOORE THOMPSON of Holly Bank, Crewe, in the County of Chester,
Mechanical Engineer, and WILLIAM WALTER GERALD WEBB, of Coppenhall Terrace,
Crewe, in the County of Chester, Mechanical Engineer, do hereby declare the nature
of this invention to be as follows:-
The object of our invention is to provide a motor of a simple and light construction
for propelling tricycles or other light vehicles and we accomplish this in the
following manner.
Referring to the drawing Sheet 1 which accompanies our specification and which
we have provided solely for the purpose of facilitating a description of the motor
which constitutes our invention and which is not intended to represent either the
size or actual details of construction. Figure 1 Sheet 1 is a sectional elevation,
and Figure 2 Sheet 1 a plan. A Figure 1 is a chamber into which is pumped or
otherwise injected a compressed charge of gas and air in the usual and well known
proportions to form an explosive mixture, the gas being either coal gas, the gas
evolved by the heating or vapourization of petroleum or other suitable mineral oil,
or any of the other well known gases or spirits employed for such purpose.
B Figure 1 is a valve which closes the chamber A and which is held on its seating
by a suitable spring C of sufficient strength to withstand the pressure of the
compressed gas in the chamber. D Figure 1 is a cover piece over the valve B
provided with suitably formed vanes or deflecting projections E shown more clearly
in the plan Figure 2, and F Figure 1 is a turbine wheel with suitably formed
vanes G revolving closely round the vanes E or deflecting projections of the cover
piece D. These vanes G are more clearly seen in Figure 2.
On the charge of compressed gas and air in the chamber A being fired by a
heated tube, gas flame, electric spark or any of the well known means the valve B
is raised from its seating and the exploded gas passes from the chamber through
the deflector vanes E of the cover piece D and then through the vanes G of the
turbine wheel F causing it to revolve at a rapid rate, the movement of this turbine
wheel being transmitted by suitable gearing to the wheel of the vehicle to be
propelled. The injection of the gas and air to the chamber A, and its compression
may be accomplished by suitable pumps driven either by the movement of the
turbine wheel or by the movement of the valve B whichever we find most suitable
and in case mineral oil is used we vapourise it either in the chamber A which will
soon become hot enough for the purpose or in a separate vessel as may be found
most suitable.

Vehicles.
We ARTHUR MOORE THOMPSON of Holly Bank, Crewe, in the County of Chester,
Mechanical Engineer, and WILLIAM WALTER GERALD WEBB, of Coppenhall Terrace,
Crewe, in the County of Chester, Mechanical 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 of our invention is to provide a motor of a simple and light construction
for propelling tricycles or other light vehicles and we accomplish this by constructing
a chamber into which is pumped or otherwise injected a compressed charge of gas
and air in the usual and well known proportions to form an explosive mixture, the
gas being either coal gas, the gas evolved by the heating or vapourization of
petroleum or other suitable mineral oil, or any of the other well known gases or
spirits employed for such purpose.
This chamber is closed by a valve which is held down by a suitable spring of
sufficient strength to withstand the compressed gas in the chamber, when the
mixture in the chamber is exploded, which may be done by means of a heated
tube, gas flame, electric spark, or any of the well known means for securing such
explosion, the valve is lifted and the exploded gas passes from the chamber through
suitably formed nozzles or deflecting vanes to a turbine wheel provided with suitably
formed vanes
on which the exploded gas acts with the result that the turbine
wheel is turned more or less rapidly; the turning of this turbine wheel we utilise
for driving a tricycle or other light vehicle.
In order that our invention may be well understood we shall now proceed more
particularly to describe the same, reference being had to the accompanying drawings
and to the figures and letters marked thereon.
Figure 1 Sheet 1 shows a sectional elevation.
a Figure 1 Sheet 1 is a circular chamber with an open top so constructed as to
afford a seating a' for a valve, at four equidistant points on the chamber are formed
projecting pieces a² and on the under side a lug as is formed. Figure 1 Sheet 1
is a valve which closes the top of the circular chamber. 61 Figure Sheet 1 is a
hollow shaft to which the valve bis attached, is the hollow in the shaft b¹.
6 is a hole communicating from the hollow in the shaft to the pump cylinder e,
6 is a ball valve held on its seating by a wire which passes up to the top of the
shaft where it is attached to a spring is a hole communicating from the
hollow shaft to the chamber a. c Figure 1 Sheet 1 is an annular ring secured to
the chamber casting and closely fitting round the valve b provided with four or
more nozzles c'. d Figure 1 Sheet 1 is a turbine wheel secured to a sleeve
casting on which is cut a worm d' this sleeve casting turns on the hollow shaft b
and a ball bearing d is introduced to take the thrust of the worm d.
e Figure 1
Sheet 1 is a circular casting forming an air pump cylinder provided with four
projecting pieces e and a pocket e³. Figure 1. Sheet 1 is an air pump piston
with a packing ring f1. In the centre of the piston is formed a pocket f into which is
loosely inserted the upper end of the hollow shaft b', f³ are a number of air valves.
Figure 1 Sheet 1 is a cross beam with four arms, the centre of the beam being
hollowed out at g' and it rests on the pocket of the pump piston, at the end of
each of the four arms are provided bolts g² which pass into four pipe stays g³ four
spiral springs g being provided to keep the cross beam and pump piston pressed
down to the position shown by the drawing. The four pipe stays form a
connection between the pump cylinder e and the chamber casting a, the stays passing
through the four projections e on the pump cylinder and the four projections a² on

page_text: the chamber casting and secured by screw nuts g'. Figure 1 Sheet 1 is an oil
or gas pump secured to the end of one of the four hollow stays 93, h' is the ram
which is attached to one of the four bolts g of the cross beam by a light connection
rod, the inlet, h³ a ball valve for the inlet, the outlet and a ball valve for
the outlet. h is a pipe connecting the pump outlet to the chamber a, a nozzle h'
attached to the pipe he being screwed into the chamber a. ; Figure 1 Sheet 1 is a
lever centred on the lug by means of which the valve b may be lifted off its.
seating. Figure 1 Sheet 1 is a collar attached to the hollow shaft band k¹ is a
spiral spring which is inserted in the pocket e² of the pump cylinder and puts.
a pressure on the hollow shaft and valve 6 and so keeping the valve on its
seating.
Figure 2 Sheet 2 is an elevation of the circular chamber end, the several parts
shown being indicated by the same letters as indicated in Figure 1 Sheet 1.
Figure 3 Sheet 2 is an elevation of the air pump cylinder end the several parts.
shown being indicated by the same figures as indicated in Figure 1 Sheet 1.
Figure 4 Sheet 3 is a plan of the turbine wheel & and the. annular ring e and
nozzles c'.
Having now described the several parts of our motor we will explain its action..
The lever being pressed down the valve b is lifted from its seating and the air
pump piston is also lifted air being drawn into the pump cylinder through the
air valves, at the same time the oil or gas pump ram his lifted by the cross.
beam g which lifts with the air pump piston and a charge of oil or gas drawn into the
oil or gas pump. The lever ; being now released the springs act on the cross.
beam and force it down together with the air pump piston the hollow shaft 1,
valve and oil pump ram. A charge of air is thus forced from the air pump
through the hole 6, through the hollow shaft & into the chamber a, through hole &
lifting ball valve 6, and at the same moment a charge of gas or oil is forced from
the oil pump through the nozzle ' into the chamber a. The chamber is heated by
means of a hot tube or other suitable means and as the oil is injected into the hot
chamber it is gasified and mixed with the air from the air puaip and the mixture is
at once exploded by the hot tube or heat of the chamber, or it may be exploded by
an electric spark.
The explosion having taken place the valve is again lifted and the exploded gas
passes through the nozzles c' to the turbine wheel d which is thus caused to rotate,
the lifting of the valve by the explosion again acts as previously described drawing
in a fresh supply of air and oil which on the valve closing again is again injected
into the chamber causing another explosion and so on.
Having now particularly described and ascertained the nature of our said inven-
ion, and in what manner the same is to be performed, we declare that what we
claim is,
1. An explosive chamber closed by a valve, substantially as described and
llustrated by the drawings.
2. An explosive chamber closed by a valve, in combination with a turbine wheel
and deflector nozzles, substantially as described and illustrated by the drawings.
3. The combination of an explosive chamber, closed by a valve, a turbine wheel,
and deflector nozzles, an air pump and an oil or gas pump, substantially as
described and illustrated by the drawings.
