PROVISIONAL SPECIFICATION.
Improvements in or relating to Vaporisers for Oil Engines and the
like.
We, WILLIAM HENRY NORGROVE, WILLIAM WESTWOOD, JAMES BATES, JOHN
CHARLES BATES, CHARLES CLIFFORD POULTNEY, and RICHARD HENRY BATES, of
the Norgrove Cycle and Engineering Company, of Tuttle Hill, Nuneaton,
Warwickshire, Engineers, do hereby declare the nature of this invention to be
as follows:-
Our invention relates to vaporisers for oil engines and the like and has for
ats objects, economy of oil, increased power, facility of determining the quantity
of oil consumed and others, some of which are hereinafter referred to.
And our
invention consists in constructing the vaporiser in such a manner that the
vapour drawn into the cylinder, by the suction of the piston, can be conveniently
regulated.
In constructing a vaporiser according to our invention we employ the usual
chamber having an inlet at one end for the air and an outlet at the other end
communicating with the cylinder. The communication between the air passage
and the chamber is provided with a conical valve having suitable ports and the
valve is also provided with a hollow stalk passing through the end of the
vaporiser. Within the chamber we mount an inner vessel by
screwing or otherwise detachably attaching it to the inner part
of the valve which is suitably modified for the purpose. The inner vessel moves
with the valve and is of such dimensions that it does not come into contact with
the walls of the chamber. Within the stalk of the valve we insert a tube and
we conduct the oil through this tube instead of directly through the stalk. The
tube may be provided with a glass or like portion so that the quantity of
passing therethrough can be seen. The inner end of the tube projects into the
vessel and its point may be tapered. This part of the tube carries a perforated
circular plate adapted to lie in a recess made in the inner face of the valve. The
perforations in the plate correspond with the ports in the valve, and the outer
end of the tube is provided with a lever or
the like by turning
which the tube and plate can be turned in such a way that the perforations in
the plate may be made to register more or less with the ports in the valve thus
increasing or diminishing, as required, the quantity of vapor to pass to the
cylinder. Suitable means may be provided to prevent accidental variation of the
relative positions of the plate and valve.
With a vaporiser constructed as above described the oil is vaporised more
perfectly than hitherto hence much less oil need be consumed and the power is
increased. No crude oil passes into the cylinder and the smoke and smeil
common to oil engines are done away with. The parts may be constructed of

page_text: iron, brass or other suitable heat conducting material, and are screwed, bolted
or similarly connected so that they may be readily separated when required.

Improvements in or relating to Vaporisers for Oil Engines and the
like.
We, WILLIAM HENRY NORGROVE, WILLIAM WESTWOOD, JAMES BATES, JOIN
CHARLES BATES, CHARLES CLIFFORD POULTNEY, and RICHARD HENRY BATES of
the Norgrove Cycle and Engineering Company of Tuttle Hill, Nuneaton.
Warwickshire, Engineers, 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:
Our invention relates to vaporisers for oil engines and the like and has for its
objects, economy of oil, increased power, facility of determining the quantity of
oil consumed, and others, some of which are hereinafter referred to. And our
invention consists in constructing the vaporiser in such a manner that the vapor
drawn into the cylinder by the suction of the piston, can be conveniently
regulated.
And in order that our invention may be properly understood and readily
carried into effect we will, in describing the same, refer to the accompanying
drawing which shows a longitudinal section of a vaporiser constructed according
to our invention. But we wish it to be understood that we do not confin:
ourselves to the precise details set forth in the said drawing and description as
these may obviously be varied or modified without departing from our invention
or exceeding the scope thereof.
In constructing a vaporiser according to our invention we employ the usual
chamber 2 having an inlet 3 at one end for the air and an outlet 4 at the other
end communicating with the cylinder. The communication between the air
passage and the chamber 2 is provided with a conical valve 5 which we foria
with suitable ports . The valve is also provided with a hollow stalk 7 passing
through the end of the vaporiser. Within the chamber 2 we mount an inner
vessel by screwing or otherwise detachably attaching it to the inner part of the
valve 5 which is suitably modified for the purpose. The inner vessel 8 moves
with the valve 5 and is of such dimensions that it does not come into contact
with the walls of the chamber 2. Within the stalk 7 we insert a tube 9 and we
conduct the oil through this tube instead of directly through the stalk. The
tube 9 may be provided with a glass or like portion (not shown) after the manner
of a water gauge for boilers, so that the quantity of oil passing there-through
can be seen. The inner end of the tube 9 projects into the vessel 8 and its point
10 may be tapered. This inner part of the tube 9 has brazed or otherwise secured
thereto a perforated circular plate 11 adapted to lie in a recess made in the inner
face of the valve 5 as shown. The perforations 12, 12 in the plate 11 correspond
with the ports 6, 6, in the valve, and the outer end of the tube 9 is provided with
a lever or the like by turning which the tube and plate can be turned in such a
way that the perforations 12, 12 in the plate 11 may be made to register more or
less with the ports 6, 6 in the valve 5, thus increasing or diminishing, as
required, the quantity of vapor to pass from the vessel 8 into the chamber 2,

page_text: (where it is mixed with the air) and thence to the cylinder. Any suitable means
may be provided to prevent accidental variation of the relative positions of the
plate 11 and valve 5.
With a vaporiser constructed as above described the oil is vaporised mor
perfectly than hitherto, hence much less oil need be consumed and the power is
increased. No crude oil passes into the cylinder and the smoke and smell
common to oil engines are done away with. The parts may be constructed of
iron, brass or other suitable heat conducting material, and are screwed, bolted
or similarly connected together so that they may be readily separated when
required.
Having now particularly described and ascertained the nature of
my said
invention and in what manner the same is to be performed I declare that what I
claim is,
1. A vaporiser for oil engines and the like so constructed that the quantity
of vapor drawn into the cylinder can be regulated, substantially as herein
described.
2. The herein described means for regulating the quantity of vapor to le
drawn into the cylinder of an oil engine or the like, substantially as set forth.
3. In an oil engine or the like, the combination with the vaporising chamber of
a valve having ports, an inner vessel carried by the said valve and means for
conducting the oil into the said inner vessel, substantially as and for the purpose
set forth.
4. In an oil engine or the like the combination with the vaporising chamber.
of a valve having ports, an inner vessel carried by the valve, an oil-conducting
tube passing into the said inner vessel and carrying a plate having perforations
adjustable to register more or less with the said ports in the valve, substantially,
as and for the purpose set forth.
5. In an oil engine or the like the employment with a vaporiser of the kind
herein described of a glass or like portion in the tube 9 so that the quantity of
oil passing through the said tube 9 can be readily determined, substantially as
herein described.
6. The improved construction and arrangement of parts in vaporisers for oil
engines and the like, substantially as herein described and as illustrated by the
accompanying drawing.
