Improvements in Valves for Gasoline Engines.
I, ALEXANDER WINTON, of 37, Bolton Place, in the City of Cleveland, in the
County of Cuyahoga and State of Ohio, United States of America, Inventor
and Mechanical Engineer, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described in and
by the following statement:-
My invention relates to improvements in valves for gasoline engines, and
pertains to a construction involving a pressure regulated inlet port valve carrying
a yielding oil valve, and an adjustable scat or nipple for said oil valve, all of
which will be fully described hereinafter and particularly pointed out in the
claims.
The accompanying drawing is a sectional view of my invention.
Referring to the drawing, A indicates the end of the explosion cylinder of a
gasoline engine which is provided with a projecting cylinder B. At the inner
end of this cylinder B is provided a valve seat C for the explosive inlet valve D1).
This cylinder B is provided with an intermediate web E, and at its outer end
with an inwardly projecting tubular head with a closed inner end and which
serves to close the outer end of the cylinder B.
The inlet port valve D is provided with a stem G which passes through an
inwardly extending tube H of the centrally disposed web E and also through
the web, and has attached to it an outwardly disposed cup-shaped piston I
which encloses the inwardly extending cap F. This piston I fits neatly the
inner bore of the cylinder B, but does not fit closely the inwardly disposed
tubular portion F of the cap. This piston I is provided with an outwardly
projecting tube J which passes through the tubular head F and through which
tube the stem G passes, and also beyond the end of the tube. Situated between
the cup-shaped piston I and the central web E is a spring K, which serves to
hold the piston normally outward and consequently to normally seat the inlet
port valve D. A pipe L is in communication at one end with the cylinder B at
a point between the centrally disposed web E and the piston I, and at its outer
end in communication with a pump actuated by the engine for supplying an
air pressure within the cylinder. The piston I is clamped to the outer end of
the valve stem G by means of the nut M, and the extending end of the stem is
provided with a longitudinal socket N, which receives an oil valve stem P.
Formed in this socket are registering longitudinal openings a and passing through
these openings and the said valve stem P is a pin b of a size to permit the valve
stem to have a longitudinal movement within the said socket. Placed within
the socket between the inner ends of this valve stem and the inner end of the
socket is a spring c which normally holds the valve and its stem outward in
respect to the said socket.
Qrepresents a tube which has one end in communication with the inner end
of the cylinder B through the opening R, and its opposite end is in communica-
tion with the atmosphere. This tube Q may have interposed between its ends
a carburetor but as that forms no part of my present invention, it is not here
shown or described.

page_text: S is an oil reservoir supported in any suitable manner and with the lower
end of which a pipe T communicates and this pipe also communicated with a
pipe at right angles thereto, and passing through this pipe U is a cut off
valve stem V. At the inner end of this pipe T a nipple dis rotatably attached,
the opposite end of the nipple being externally screw threaded and passing through
an internally screw threaded shoulder e formed upon the pipe Q. This nipple
is provided at its inner end with an elongated valve stem opening f; the inner
end of this opening is formed into a valve seat g and receives the valve upon
the outer end of the valve stem P.
From this description it will be noted that the inner end of the nipple
furnishes a support and a guide for the outer end of the valve and valve stem,
as the openings in the nipple is made sufficiently small to always insure the
point of the needle valve registering with its converging tapering wall when
moved into a closed position.
It is desirable to provide at all times a tight fitting of the oil valve, when it
is seated, and to accomplish this the nipple is longitudinally adjustable by screw-
ing it through the enlargement e upon the tube Q, and clamping it in its
adjusted position by means of a clamping nut i.
In
In adjusting the nipple, and thereby regulating the seating of the oil valve,
the nipple is turned until it is noted that the pin b which unites the opposite
end of the valve stem P to the inlet port valve stem G has a slight inward
or backward movement and then the nipple is tightened by the lock nut i.
this way any wear of the valve and the valve seat is readily taken up, and it
also enables me to provide a perfect seating of the valve which will not necessitate
the turning up of the cut off valve V when the engine is not running. The nipple
is provided intermediate its ends with a projection m adapted to receive a wrench
for adjusting it.
By means of this adjustment the seating of the oil valve and of the inlet
port valve can be made to occur at the same time, and yet a tight fit of the
oil valve accomplished to prevent any leaking of the oil when the engine is
not in operation.
The inwardly extending tubular cap F and the outwardly disposed cup-
shaped piston I furnish a dash pot for preventing the hammering of the inlet
port valve and also of the oil valve which prevents not only injury and wear to
the valves and the valve seats but also prevents a disagreeable noise which other-
wise would occur.
In operation, when the inlet port valve D is moved inward from its seat for
admitting the explosive material, the needle valve is likewise removed from its
seat permitting a flow of liquid to the pipe Q and this is conveyed through
the said pipe to the explosive inlet port through the opposite end R of the pipe Q.
This arrangement insures a positive feed of the liquid to the pipe Q at each
inward movement of the inlet port valve since the needle valve is connected
to the stem thereof as before described. When it is desired to absolutely cut
off the flow of the liquid, (as when the engine is out of operation) the valve
is screwed to its seat which will cut off the flow of liquid as will be readily under-
stood from the drawing.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed I declare that what
I claim is

mediately disposed web within said cylinder, the stem having an outwardly

and projecting within the cup-shaped piston, and a pressure communication with
the cylinder between the piston and the centrally disposed web, substantially
as described.
