PROVISIONAL SPECIFICATION.
Improvements in Carburetters for Use in Gas, Oil, or Spirit Engines.
ALF DOUGILL, Engineer, 5, Vernon Road, Leeds, and JOHN MARKS, of No. 10,
Roseville Terrace, Roundhay Road, Engineer, Leeds, do hereby declare the
nature of this invention to be as follows:-
That we have a body casting of any metal containing a conical valve with
an upper and lower seat, this acts on two seats in the body casting, and is held
down to its seats by its own weight or a spring, it has an extended spindle
downwards, which may be hollow or solid, if hollow it may be perforated at
top close under lower seat, if solid it may have grooves or flats on solid spindle,
to allow the oil or spirit to pass up to the lower valve seat where it then passes
to a chamber which runs down from the lower valve seat to bottom of outer
casting, thus a chamber is formed the inner wall of which acts as a guide to
the valve spindle. In the outer casting below the level of the lower valve seat
is a series of holes, the size of which, is regulated by a sliding collar for
regulating the supply of air.
On the upper side of the body casting there is an outlet to the motor. On
the bottom of body casting is the oil or spirit inlet, which communicates with
the lower valve spindle. On the top of outer casting is fitted a relief valve
to stop the action of the carburetter and to facilitate starting the motor.
Thereby forming an entirely automatic carburetter which is perfectly safe
and prevents any waste of oil or spirit whatsoever.
We declare the nature of our claim is the conical two seated valve and spindle
in combination with the inner chamber and adjustable collar and air inlets and
the relief valve or adjustable cock on the top.

Improvements in Carburetters for Use in Gas, Oil, or Spirit Engines.
We, ALF DOUGill, Engineer, 5, Vernon Road, Leeds, and JOHN MARKS, of
No. 10, Roseville Terrace, Roundhay Road, Leeds, 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:---
This invention has for its object, the construction of carburetters in such
a manner, that the action of the same when set to work is automatic, and

page_text: arranged so as to prevent waste of oil or other liquid to be vaporised, and more
readily adjusted, as may be required to effect the desired vaporisation, than
is the case with carburetters constructed in the manner as hitherto.
In order that our invention may be fully understood, we will describe the
same in detail by making reference to the accompanying sheet of drawings
in which,
Fig. 1, represents a sectional elevation of a carburetter constructed according
to our invention, and suitable for a gas, oil, or spirit engine of the locomotive
type.
Fig. 2, is a plan of the same.
Fig. 3, is a cross sectional plan through line a, b.
Fig. 4, is a sectional elevation of a modified relief valve fitted to the upper
portion of our improved carburetter.
Fig. 5, is a plan of the same, and
Fig. 6, a sectional elevation of a carburetter constructed according to our
invention, such as may be applied to an engine of the stationary type.
In the accompanying drawings in which similar letters and numerals of
reference indicate corresponding parts in the several views, A, indicates the
body or outer casting provided with an oil or spirit inlet B, to the interior, and
with an outlet C, to the motor or the like; and within the body or outer
casting A, we form in any convenient position an upper and lower valve
seat I), and E, respectively, for the reception of a conical valve F, which may
be kept in contact with the before mentioned seats, by its own weight or by
the aid of a compressed spiral spring G, or the like.
The conical valve F, is automatically raised at each stroke of the engine as
usual, and is provided with an extended spindle F¹, which may be hollow with
perforations at or near the top of same extending to the exterior of the spindle,
or by preference the said spindle may be provided with a number of grooves H,
on its circumference for the passage of oil or spirit on the opening of the conical
valve F, to the annular space S, where it becomes incorporated with atmospheric
air admitted to the said annular space through openings K, formed in the
lower portion of the outer casting.
The admixture of oil or spirit and air is vaporised in the ordinary manner
and escapes through the chamber 1, upon the valve F, being automatically
raised at each stroke of the engine.
To the extended threaded portion L, of the outer casting A, we mount an
adjustable socket M, with a flange or collar M¹, the inner circumference of
which is in close and sliding contact with the lower portion of the outer
casting A, and by the raising or lowering of the adjustable socket, the flange
or collar M¹, is regulated to cover the openings K, thereby adjusting the area
of the said openings as may be required for admitting the required amount
of atmospheric air to the annular space S, of the carburetter.
To the top of the outer casting A, we place a relief valve such as an ordinary
tap O, as shown, by which means, should an additional amount of atmospheric
air be required to be admitted at any time for stopping the action of the
carburetter, or facilitating the starting of the motor, the said tap or valve is
opened and atmospheric air admitted to the space P, above the conical valve F:
In place of the relief valve or tap O, the carburetter may be provided with
a valve such as shown by Figs. 4 and 5, which consists of a plate Q, having a
handle R, projecting therefrom and curved slots S¹, S¹, engaging with the stop
studs T, T, secured to lugs U, forming part of the outer casting A, within which
is a collar Q¹, projecting from the plate Q, the said collar filling the inner
circumference of the outer casting A, thus forming a valve with an opening
at Q, for allowing the vaporised oil or the like to pass to the motor.
Through the said plate Q, we form one or more openings W, communicating
with the interior of the carburetter, and on the top of said plate is mounted
on centre stud V, a valve plate X, having openings W₁, corresponding with

page_text: those through the plate Q, so that on turning the valve plate X, until the
openings W, in plate Q, are altogether or partly uncovered, an additional amount
of atmospheric air is admitted to the carburetter for the purpose as before
described.
The carburetter Shown in sectional elevation by Fig. 6, is provided with a
conical valve 1', engaging with an upper and lower seat D, and E, respectively,
the inlet of oil or spirit to the extended valve spindle F¹, through openings F,
and in order that the oil or spirit may have better access to the grooves H, we
form the annular groove H¹, whereby the oil or the like may pass around said
spindle F¹. The admission of atmospheric air to the annular space S, is through
opening Y, to which may be attached an ordinary valve or tap for regulating
the supply of atmospheric air, the relief valve at the top being of the same
construction as hereinbefore described in connection with Figs. 1 to 5.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
Carburetters provided with two valve seats D, and E, with which is combined
a conical valve F, having an extended spindle F1, affording means for the flow
of oil or the like to the annular space S, means for regulating the admission
of air to the interior of apparatus all arranged substantially in the manner as
shown and described and for the purpose as hereinbefore set forth.
