page_text: Improvements appertaining to Oil Engines.
I, FRANK LISTER of Keighley in the County of York, Consulting Engineer, do
hereby declare the nature of this invention to be as follows, that is to say :-
In connection with the class of engines or motors wherein oil is used as the medium
or source of energy the same being supplied to and exploded or consumed within
said engine's cylinder so as thus to impart motion to their pistons, very great
difficulty is experienced in supplying said oil in proper quantities or proportions
relatively with the air therein to enable or insure its thorough consumption, in most
cases said oil being supplied thereto in such excessive quantities as to cause
same to overflow and spread upon the heated working parts in said engines thus
producing a most undesirable odour as well as creating undue waste.
To obviate these disadvantages and produce means that may be used in connection
with said engines to regulate the supply thereto of the motor oil in such quantities
or proportions as may be desired or found necessary for the varied requirements is
the object of this invention, and this object. I attain by the employment of the
following device.
In suitable proximity with the passage through which air is drawn into the engine's
cylinder, such proximity being preferably so as to intercept the air as it travels
therethrough, I mount a perforated carrier, (hereinafter more fully described) which I
arrange to pass or extend into the tank or receptacle containing the oil to be supplied
to the cylinder.
This perforated carrier is raised or moved to bring such of the oil as its
perforations may contain out of the receptacle, to be presented to or to intercept the
passage through which the air is being drawn and travels to the cylinder by which
ineans said current of air carries with it all the oil that lies in its path through the
perforations, forward into the cylinder to be exploded or consumed as. is well
understood.
Now, as the size of these perforations may be varied or as their numbers or capacity
for holding the oil may be increased or diminished, it will be seen that their
capacity for bringing the oil into the path through which the air travels may be
regulated to meet any requirements that the varied conditions of the engine may
demand.
To regulate the capacity of the perforated carrier after such has been brought by
experiment or otherwise approximately near what is required, means may be
employed, such as a rotary or other kind of valve or tap, for increasing or diminishing
the size of the air passage referred to thus the current will pass through more or will
not pass through as great a number of the perforations in said carrier as the case
may be, and when this kind of regulating device is used it may be controlled or
operated by the momentum governor of the engine.
As a convenient carrier I may have it of some flexible material as leather (suitably
perforated) which will thus allow me to pass it around rollers for causing it to
descend into and ascend out of the oil receptacle to raise or supply same as desired.
Or again I might employ an absorbent material such as is used for lamp wicks for

page_text: example, in which case capillary attraction might assist or even partly supplant the
movement for raising or supplying the oil, while further the porosity of the material
would meet the requirements of the perforations and allow the passage of the air.
Or the perforated carrier might be of metal and arranged to have reciprocatory or
rotary motion for bringing the oil into the desired position from the general supply
in the receptacle.
It will be seen that instead of the above described oil carrier being made to
intercept the main air inlet to the cylinder it may be mounted in the supplementary
air inlet arranged to be operated and closed at the proper times by appropriate valve
mechanism operated by suitable cains or the engine's governor.

I, FRANK LISTER of Keighley in the County of York, Consulting 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, that is to say :-
In connection with the class of engines or motors wherein oil is used as the medium
or source of energy the same being supplied to and exploded or consumed within
said engine's cylinder so as thus to impart motion to their pistons, very great
difficulty is experienced in supplying said oil in proper quantities or proportions
relatively with the air therein to enable or insure its thorough consumption, in most
cases said oil being supplied thereto in such excessive quantities as to cause
same to overflow and spread upon the heated working parts in said engines thus
producing a most undesirable odour as well as creating undue waste.
To obviate these disadvantages and produce means that may be used in connection
with said engines to regulate the supply thereto of the motor oil in such quantities
or proportions as may be desired or found necessary for the varied requirements is
the object of this invention and this object I attain by the employment of, the device
hereinafter described and as illustrated by the accompanying sheet of drawings in
which :--
Fig. 1 is a sectional side elevation of mechanism made in accordance with my
invention.
Fig. 2 is also a sectional view of my improved mechanism, but illustrates same as
seen in a direction at right angles to that shown by Fig. 1.
In suitable proximity with the passage through which air is drawn into the
engine's cylinder, such proximity being preferably so as to intercept the air as it
travels therethrough, I mount a perforated or porous carrier 6 which I
arrange to pass
or extend into the tank or receptacle c containing the oil to be supplied to the
cylinder.
This perforated or porous carrier b is raised or moved to bring such of the oil as
its perforations or pores may contain out of the receptable c, to be presented to or to
intercept the passage a a¹ through which the air is being drawn and travels to the
cylinder, by which means said current of air carries with it all the oil that lies in its
path through the perforations forward into the cylinder to be exploded or consumed
as is well understood.
Now as the size of the perforations or the surface of the porous carrier b presented
to the passage a may be varied or as their capacity for holding oil may be otherwise

page_text: increased or diminished, it will be seen that the quantity of said oil placed by said
carrier to intercept the passage a a¹ for the air may be regulated to meet any
requirements that the varied conditions of the engine may demand.
To regulate the quantity of oil drawn into the cylinder from the carrier b after
such has been brought by experiment or otherwise approximately near what is
required, means may be employed such as a rotary or other kind of valve or tap for
increasing or diminishing the size of the air passage a or a¹ thus the current will pass
through more or will not pass through as great a number of the perforations or pores
in said carrier b as the case may be, and when this kind of regulating device
is used it may be controlled or operated by the momentum governor of the engine.
As a convenient carrier it may be of flexible material as leather (suitably
perforated) which will thus allow it to pass around rollers d, f so that on these being
rotated as by the cord or driving belt g (receiving its motion from any motor part of
the engine or otherwise) said carrier 6 will be caused to descend into and ascend out
of the oil in the receptacle c to raise or supply said oil as desired. Or again I might
employ an absorbent material such for example as is used for lamp wicks (and this is
the kind of carrier I preferably use so that it is the one alone shown in the drawings)
in which case capillary attraction might assist or even partly supplant the inovement
for raising or supplying the oil, while further the porosity of the material answers the
same ends as the perforations in the other kind of carriers as far as affording freedom
for the passage of the air.
Or the perforated carrier might be of metal and arranged to have reciprocatory or
rotary motion for bringing the oil into the desired position from the general supply
in the receptacle.
It will be seen that instead of the above described oil carrier being made to
intercept the main air inlet to the cylinder it may be mounted in a supplementary
air inlet arranged to be operated and closed at the proper times by appropriate valve
mechanism operated by suitable cams or the engine's governor.
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. In mechanism for supplying liquid to form the explosive mixture for motor
engines, a perforated carrier and means for operating same substantially as herein
specified.
2. In mechanisin of the class described, a carrier of porous material arranged to be
operated to the end herein specified substantially as herein set forth.
3. The improved mechanism for supplying liquid to form the explosive mixture in
motor engines herein described the same being constructed and arranged to operate
substantially as set forth.
