Improvements in Governing and in Regulating the Supply of Oil to
Petroleum or Hydro-carbon Motors.
We, JAMES EDWARDS WEYMAN, and JAMES ARTHUR DRAKE, both of the
Church Acre Iron Works, Guildford, in the County of Surrey, Mechanical
Engineers, do hereby declare the nature of our said invention for "IMPROVEMENTS
IN GOVERNING AND IN REGULATING THE SUPPLY OF OIL TO PETROLEUM OR
HYDRO-CARBON MOTORS to be as follows:-
:-
"
The objects of our invention are to provide a simple inexpensive and effective
arrangement for supplying and regulating the oil to motors as herein described.
Our improvements consist in an arrangement and combination of parts by means
of which the pump which supplies the oil to the cylinder of the motor may be
actuated or regulated or actuated and regulated by a suitably constructed governor
and when required to actuate as well as regulate the pump we by preference employ
a governor of the inertia type such as are sometimes applied to gas engines and the
like motors.
Connected with such a governor we construct an arm or lever by which the
pump plunger is actuated, the end of such arm or lever or the end of the pump
plunger we construct in the form of a knife edge, such knife edge, being formed
and arranged to fit and work with a corresponding end or knife edge on the arm or
plunger or both as the case may be, thus the pump, the governor and the arm
referred to are so fixed in relation to one another, that when the parts have once
been adjusted for the speed at which the motor is required to work and so long as
it runs at or below the required speed, the knife edge of the governor arm or of the
pump plunger or both remain in line and come in contact at every stroke with the
corresponding ends of each other, as the case may be, thereby forcing the plunger
in and making a stroke by which the necessary amount of oil is supplied to the
cylinder of the motor.
The return stroke of the pump plunger being effected by a spring or weight or
other equivalent means, the arm of the governor and the pump plunger remain in
contact as the governor recedes, but immediately the speed becomes greater than
that to which the governor is adjusted, then by virtue of the inertia of the ball of
the governor, the arm of the governor is depressed or moved out of line with the
point of contact on the pump plunger, whereby they miss each other on the return
stroke and a stroke or strokes of the pump is lost. The supply of oil is thereby
cut off and remains cut off until the speed of the motor becomes normal, when the
working parts having returned to their proper positions the stroke of the pump and
the feed of the oil is resumed.
As a modification of the arrangement herein described for governing and regulating
the supply of oil to such a motor, the pump may be worked by a crank or eccentric
in the ordinary way, but the pump rod though working in line with the plunger is
not connected but is brought in contact by a knife edge or other suitable arrange-
ment similar to that as herein previously described, the pump rod we connect to
the governor by a bridle so that when once adjusted to a certain speed and so long
as it remains at or below that speed the pump rod would continue in line with the
plunger, but when the speed was exceeded the pump rod would by the action of
the governor be drawn out of line with the plunger and a stroke or strokes would
be missed in a manner similar to that herein previously described.

page_text: With this modified arrangement an ordinary pendulum or centrifugal governor
may be employed.

Improvements in Governing and in Regulating the Supply of Oil to
Petroleum or Hydro-carbon Motors.
We, JAMES EDWARDS WEYMAN, and JAMES ARTHUR DRAKE, both of the
Church Acre Iron Works, Guildford, in the County of Surrey, Mechanical
Engineers, do hereby declare the nature of our said invention for "IMPROVEMENTS
وو
IN GOVERNING AND IN REGULATING THE SUPPLY OF OIL TO PETROLEUM OR
HYDRO-CARBON MOTORS and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
The objects of our invention are to provide a simple, inexpensive and effective
arrangement for supplying and regulating the oil to motors as herein described.
Our improvements consist in an arrangement and combination of parts by means
of which the pump which supplies the oil to the cylinder of the motor may be
actuated or regulated, or actuated and regulated, by a suitably constructed governor,
and when required to actuate as well as regulate the pump, we by preference
employ a governor of the inertia type such as are sometimes applied to gas engines
and the like motors.
Connected with such a governor we construct an arm or lever by which the
pump plunger is actuated, the end of such arm or lever and the end of the pump
plunger are each constructed in the form of a knife edge, such knife edges being
formed and arranged to fit and work with each other, either directly on the pump
plunger, or by a corresponding knife edge suitably connected to an intermediate
lever which in most cases we employ to actuate the pump ram, thus the pump, the
governor, and the arm referred to are so fixed in relation to one another, that when
the parts have once been adjusted for the speed at which the motor is required to
work, and so long as it runs at or below the required speed, the knife edges remain
in line and come in contact at every stroke with the corresponding ends of each
other, as the case may be, thereby forcing the plunger in and making a stroke by
which the necessary amount of oil is supplied to the cylinder of the motor.
The return stroke of the pump plunger being effected by a spring or weight or
other equivalent means, the knife edges on the arm of the governor and the pump
plunger or intermediate lever actuating the same remain in contact as the governor
recedes, but immediately the speed becomes greater than that to which the governor
is adjusted then by virtue of the inertia of the ball of the governor the arm of the
governor with its knife edge is depressed or moved out of line with the point of
contact on the pump plunger or intermediate lever whereby they miss each other
on the return stroke and a stroke or strokes of the pump is lost. The supply of
oil is thereby cut off and remains cut off until the speed of the motor becomes
normal, when the working parts having returned to their proper positions the stroke
of the pump and the feed of the oil is resumed.
As a modification of the arrangement herein described for governing and
regulating the supply of oil to such a motor, the pump may be worked direct by a
crank or eccentric in the ordinary way but the pump rod though working in line
with the plunger is not connected but is brought in contact by a knife edge or other
suitable arrangement similar to that herein previously described, the pump rod we
connect to the governor by a bridle so that when once adjusted to a certain speed
and so long as it remains at or below that speed the pump rod would continue in

arrange-
k, is the spring for actuating the return stroke of the pump ram by this
ment the intermediate lever employed for actuating the pump ram is likewise
utilized for actuating a valve or valves for regulating the admission of vapour from
the vaporizer to the combustion chamber or for some such similar purpose.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. In hydro carbon motors known as oil engines the arrangement and combination
of parts and appliances comprising the governor, d, with the arm or lever, e, con-
nected thereto, carrying the knife edge, f, the intermediate pivotted lever, h, with
the knife edge g, attached thereto, the knife edges, f, and y, the spiral spring, k, or
its equivalent for actuating the return stroke of the pump together with the
appurtenant fittings by means of which the supply of oil to the engine may be
governed and regulated in the manner and for the purposes substantially as herein
described and illustrated on the accompanying sheet of drawings.
2. In hydro carbon motors known as oil engines the arrangement and combination
of parts and appliances as described in Claim 1, but with the knife edge, g, attached
direct on to the pump plunger or rod, j, in such a manner so as to work with the
knife edge, f, on the governor arm, without the intervention of the lever, h, in the
manner and for the purposes, substantially as herein described.
3. In hydro carbon motors known as oil engines the arrangement and combination
of parts and appliances as herein described in the modified arrangement for
governing and regulating the supply of oil where an ordinary pendulum or
centrifugal governor is employed in the manner and for the purposes substantially
as herein described.
