Improvements in Oil Motor Engines.
We, ROBERT DINSDALE CUNDALL, WILLIAM DENTON CUNDALL, and
HENRY CORDINGLEY CUNDALL, of the Firm of R Cundall and Sons, of the
Airedale Iron Works, Shipley, in the County of York, Machine Makers and
Engineers, do hereby declare the nature of this invention to be as follows:
This invention relates to oil motor engines, and our improvements consist,
firstly, of an improved construction and arrangement of vaporiser, and secondly,
of an improved means to be employed for supplying given quantities of oil to
vaporisers.
In carrying out the firet part of our invention, the improved vaporiser comprises
a suitably shaped box or chamber, to which is connected a lamp for heating the
ignition tube, the said lamp being preferably surrounded by a cover made with
openings for supplying atmospheric air to the said lamp. The chamber of tho
vaporiser is made with an inverted dome or the top of the dome is made with a
cavity against which the flame and heat from the lamp unpinges. The dome as
well as the cavity may be corrugated so as to increase the heating sui face. By
this means the oil is quickly vaporised or converted into vapour. An ordinary
form of mushroom valve is employed to admit atmospheric air to the vaporiser,
which air mingles with the vaporised oil or vapour previous to being ignited by
the ignition tube.
The second part of our invention, which relates to means to be employed for
supplying given quantities of oil to the vaporise, and our improvements consist
in the use of a vessel, the centre of which is provided with a small cup or thimble
with an adjustable disc. The oil is pumped into the vessel and conveyed by a
pipe to the cup or thimble, which 18 in communication with the vaporiser for
supplying the latter with the necessary oil, but such pump supplies mole oil than
the cup or thimble 18 capable of receiving, therefore the overflow or superfluous
oil runs from the disc into the bottom of the vessel, Euch superfluous or overflow
oil is utilised for supplying the lamp for heating the vaporiser. The overflow oil
in the vessel can be kept at a suitable level by a syphon.
The adjustable disc 18 Ecrewed into its position, and it can be raised aud
lowered so as to enlarge or lessen the capacity of the cup or thimble which
supplies oil to the vaporiser. By this means the vaporiser is supplied with a given
quantity of oil for each explosion, consequently the force or power of the explosions
are qual, thus n aintaining a regular and uniform action of the engine.

We, ROBERT DINSDALE CUNDALL, WILLIAM DENTON CUNDALL, and
HENRY CORDINGLEY CUNDALL, of the Fum of R Cundall and Sous, of the
Airedale Iron Works, Shipley in the County of York, Machine Makers and
Engineers do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascontained in and by the
following statement :-
This invention relates to oil motor engines, and our improvements consist,
firstly, of an improved construction and ariangement of vaporiser, und socoudly,
of an improved monus to be employed for supplying given quantities of oil to
vaporisers
In carrying out the first part of out invention, the improved vapouser comprises
a suitably shaped box or chamber, to which is connected a lamp for heating the
ignition tube, the said lamp being preferably surrounded by a cover made with
openings for supplying atmospheric air to the said lamp.
The second part of our invention relates to means to be employed for supplying
given quantities of oil to the vaporiser, and our improvements consist in the uso of
a vessel, the centre of which is provided with a small cup on thumble with an
adjustable disc or regulator.
The accompanying drawings illustrate our improvements in oil motor engines,
where Fig. 1 is sectional elevation of a vaporiser constructed according to our
invention. A represents the end of the engine cylinder, and B the vaporiser, the
upper internal surface of which is provided with nu asbestos lining C to retain the
beat. Near the bottom of the vaporiser is a lamp D, the flame of which gives off
sufficient heat as to make the ignition tube E' sufliciently hot as to ignito the
combustible mixture.
The chamber B of the vaporiser is provided with an inverted dome F against
which the flame and heat from the lamp impinge. The lamp is surrounded by a
dome G having openings H to permit the heat to escape to the vaporisei.
An ordinary form of mushroom valve I is employed to admit atinospheric air to
the vaporiser, which air mingles with the oil previous to being ignited by the
ignition tube.
Our improved apparatus for supplying given quantities of oil to the vaporiser is
shewn in Fig. 1, and also on an enlarged scale at Figs 2 and 3.
For carrying out our invention, we fix to the top of the vaporiser a cup or
chamber J in the bottom of which is a plug or gland L having a central opening
for the reception of the valve spindle M; there is also a valve seating at the
bottom of the screwed plug L for the reception of the valve N at the bottom of
the spindle.
Near the top of the plug L we screw a washer or small cup O more clearly
shewn in Fig. 2, which said washer or cup can be adjusted so as to leave an opening
for the reception of oil, which opening can be made either large or small according
to requiements by screwing the washer O further up the bush L or lower down.
The oil is pumped and conveyed through pipe P to the cup or thimble O, and
every time the valve N is opened (which is effected by mechanism not shown in
the diawings) the said valve permits oil to drop into the dome F, and simultaneously
with the opening of the oil valve N the air inlet valve I is also opened admitting
air to blend with the oil which is vaporised by the ignition tube.
In practice it 18 customary to feed the oil to the cup O quicker than it can be
used, therefore the overflow or surplus oil runs from the disc O into the bottom of
the vessel J, such superfluous oil or overflow being conveyed away through pipe Q

page_text: and it may be utilised for supplying the lamp with oil or the said overflow oil may
be employed for any other purpose required. By this means the vaporiser is
supplied with a given quantity of oil for each explosion, consequently the force or
power of such explosion is equal, thus maintaining a regular and uniform action
of the engine.
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 18:-
Firstly. The construction of a vaporiser for oil engines, formed with a chamber B
and inverted dome F, substantially as shewn and described
Secondly. In oil motor engines, the combination therewith of adjustable means
for supplying oil, consisting of a regulating washer or cup O and a valvo N
employed in the manner and for purposes substantially as herein shewn and
described.
Thirdly. In oil motor engines, the means or method of supplying oil thereto,
intermittently, by means of the iegulating washer or cup O, outlet valve N, in
combination with means for running off the surplus or overflow oil in manner
described and shewn in the drawings.
