Improvements in Valves or Feeders for Gasoline Engines.
I, ALEXANDER WINTON, of 37, Bolton Place, 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 to be as follows:-
My present invention relates to improvements in oil valves or feeders for gaso-
line engines, and the invention pertains to that class of engines in which a
quantity of gasoline or air are drawn together within the explosion chamber and
exploded.
The object of my present invention is to provide a specially constructed spring
connection for operating the gasoline valve whereby it has a yielding seating
action to insure its tight fit, while at the same time it is given a positive opening
and closing movement; the parts also being constructed to permit of adjustment
for taking up the wear of the valve and its seat, and to prevent noise.
I carry out the object of my invention by providing the engine proper with
a pressure closed explosive inlet valve, by connecting with this valve a piston
which is effected by pressure from a pump or other source of supply actuated by
the engine. An oil supply is provided having an exit, and this exit is opened
and closed by a valve which is connected with the stem of the inlet port valve.
This connection consists of a spring preferably U-shape in form having one
end connected with the said inlet port valve stem and the opposite end connected
with the said oil valve. This spring has its tension normally outward and is held
by means of an adjustable connection to the end of the inlet port valve. This
connection however is so constructed as to permit the movement of the free end
of the spring, so that when the oil valve is seated by the closing of the inlet port
valve, a yielding spring seat is provided therefor which will provide always a tight
seating of the oil valve and also enable it to automatically take up the wear of
either the valve or its seat. The spring is of such a nature that it itself serves
as the means for opening and closing the valve through the medium of the
movement of the inlet port valve, to the stem of which one end of the spring
is connected as before stated.
For the purpose of preventing the hammering noise in the seating of the inlet
port valve, and also the same trouble with the oil valve, a dash pot or air
chamber is provided at the opposite side of the piston which is connected with the
inlet port stem from that side to which the air pressure is admitted. This dash
pot or air chamber prevents the hammering noise of the two valves and con-
sequently prevents considerable wear upon the valves and their seats on account
of the hammering action where such a dash pot or chamber is not provided.

page_text: I, ALEXANDER WINTON, of 37, Bolton Place, 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 and ascertained in and
by the following statement:-
My invention relates to improvements in oil valves or feeders for gasoline
engines, and pertains to that class of engines in which a quantity of gasoline and
air are drawn together within the explosion chamber and exploded.
The object of my present invention is to provide a specially constructed spring
connection for operating the gasoline valve, whereby it has a yielding seating
action to insure its tight fit, while at the same time it is given a positive opening
and closing movement, the parts also being constructed to permit of adjustment
for taking up the wear of the valve and its seat and to prevent noise.
In the accompanying drawings,

Figure 1, is a sectional view of the explosive end of a gasoline engine cylinder, 1
showing my invention applied thereto.
Figure 2, is a detail view of the adjusting bolt.
Figure 3, are views of the clamping nut.
Reference being had to the drawings, A is the explosion end of a cylinder,
and projecting rearward from this end of the cylinder is a chamber B, the said
chamber having an open inner end in communication with the cylinder and pro-
vided with an opening C for the explosive mixture,.
The explosion inlet valve K is provided with a valve stem k, passing longi-
tudinally through the chamber or cylinder, B, the outer end of the stem being
provided with a piston II within said cylinder, and communicating with this
cylinder so as to cause a pressure upon the said piston H is a pressure supply
pipe 7. Pressure is supplied to this pipe through the medium of a pressure
supplying pump, which is actuated by the engine in any desired manner.
In operation the pump supplies pressure to the cylinder, which causes an outward
pressure against the piston, which holds the explosive inlet valve K to its seat
with more or less force, according to the pressure upon the piston which is varied
according to the speed of the engine, and consequently the speed of the pump,
as will be readily understood. A spring n is provided for normally holding the
explosive inlet valve to its seat and the parts in their normal operative position.
My present improvement relates particularly to a valve for admitting a pre-
determined amount of hydrocarbon fluid, such as gasoline, at every other stroke
of the engine piston, which is the usual operation of explosion engines.
The gasoline tank 2 is supported at any desired point, and a supply pipe 3
extends therefrom into a mixing pipe 4. This mixing pipe 4 is provided with
an opening C, which communicates with the explosion end of the cylinder at a
point outside of the inlet valve. When the piston moves outward, the valve K
is opened by suction and the hydrocarbon valve J, which is preferably of the
well known needle or pointed construction, is moved from its seat 6, thus admitting
a small quantity of fluid within the pipe 4, which is drawn into the explosion
end of the cylinder, together with air that is mixed therewith, and preferably
through a carbureter 7. (Shown in dotted lines in Figure 1, but which forms
no part of the present invention.) This carbureter may be of any desired form
without affecting in any manner my present invention. The hydrocarbon
valve J is connected with the end of the stem of the valve K through the medium

page_text: of a nut G, which clamps it into position, the said nut in turn being clamped by
means of a bolt G¹. A spring 1 (preferably of U-shape in form, as shown in
Figure 1) has one end clamped to the stem of the valve K, while its opposite end
is connected with the hydrocarbon valve J, and the spring, being of the expanding
form, normally forces the valve J against its seat. The movement of the spring,
however, is regulated through the medium of a regulating bolt H', which has
one end screwed into a lug upon the nut G and its opposite end provided with
an elongated opening f, through which one end of the spring I passes, as also
clearly illustrated in Figure 1. This opening in the rod H' allows just enough
backward motion of the spring to accomplish a tight seating of the valve J, while
at the same time the rod H forms a positive pull upon the valve for removing it
from its seat through the medium of the stem of the inlet valve K. This con-
struction enables me to use a strong spring I, thereby making the tight closing.
of the valve more sure, and yet enabling me to secure a positive movement of the
valve, both of which are very desirable. By means of the adjustable feature the
valve may be adjusted for the purpose of taking up the wear of either the valve
or of its seat. It will be thus seen that a positive connection is provided for
withdrawing the valve from its seat, and practically a positive, and yet a yielding,
connection is provided for seating the valve. This construction in use upon a
motor vehicle has been found to produce a most satisfactory arrangement, one
which is very sensitive, durable, and not liable to get out of order, in that it
automatically provides for the tight seating of the valve and a small wear thereof.
It is also desirable in motors for vehicles to make them as noiseless as possible,
and to avoid the clicking noise caused by the seating of the oil valve and also the
explosive inlet valve K, I provide a dash-pot or air cushion situated between the
two. This is provided by having the cylinder or chamber B extend beyond
the piston H to form a space M. The extremity of this cylinder is closed by a
cap N, and this cap is provided with a passage or passages P. Through the
medium of this arrangement an air cushion is provided at the outer side of the
piston, as will be readily understood, whereby when the valves are being seated
they are prevented from a sudden contact with their seats, which avoids the click-
ing noise common to mechanisms of this character, and yet it permits a firm
and tight seating of both of the valves. It will be noted that this air cushion,
situated as here shown, between the explosion inlet valve and the oil valve, serves
a double function in that it regulates the seating of both valves, thus preventing
wear upon the valve seat and also, as before stated, preventing the undesirable
constant clicking which would otherwise occur.
