PROVISIONAL SPECIFICATION.
An Improved Feed for Supplying Oil to Burners in Controlled
Quantities.
WILLIAM REYNOLDS, King Street, Coventry, Lamp Manufacturer, LEONARD
GETHIN ASTLEY, Broadgate, Coventry, Oil Merchant, do hereby declare the nature
of this invention to be as follows:-
A tank is constructed of metal or other suitable material and on the top is affixed
a tap or cock through which the tank may be filled with oil.
A tube so fixed as to pass from below the bottom through to nearly the top of
the tank and a smaller tube prefrably by the side of the former passes through the
bottom a short distance up inside the tank. The portions of these tubes projecting
below the tank may be enclosed in an open ended tube attached to the outside of
the bottom and the mouth of this tube be provided with a valve seating. A valve
attached to a lever is so arranged as to close when desired the mouth of this tube
and by doing so also close the two tubes inside it. The valve lever is connected
prefrably by a spiral spring with the thumb piece or handle of the cock at the top
of the tank either directly or by the medium of an angle piece and chain in such
a manner that when the cock is shut off the valve will fall and uncover the seating
and when at open the valve will close on its seating and incidentally also
cover the two inner tubes.

The spiral spring should be so arranged that the act of opening the cock will
cause the valve to close the bottom tubes before the cock is actually open the spread
of the spring allowing the cock to be completely opened. In the same manner
when the cock is being shut off, the valve will remain shut until the turning of
the cock handle removes the tention on the spring.
Except for the tubes and cock as described the tank should be air and oil tight.
When the tank is arranged as above it is convenient to stand it on another tank
of which it forms the cover and to affix a pipe to the bottom tank for the purpose
of conveying the oil to the burners. A waste pipe may also be affixed to the bottom
tank to convey away any possible excess of oil.
To operate this mechanism the cock is opened and the tank filled with oil. The
act of opening the cock will close the bottoms of the tubes by the valve and prevent
any flow of oil. The cock is shut and this will open the valve and oil will run out
of the short tube and air flow in through the long tube until the oil in the bottom
tank rises and stops the inflow of air when the oil flow will cease. As the burners
supplied from one tank should be on the same level as the mouths of the tubes
just mentioned a seperate feed will be necessary for each level and these may be
connected by a common supply pipe with spur-pipes or feeders to the cocks on the
tops of the tanks. In this case an auxilliary air cock will be necessary also on the
top of the tank and should be connected with the supply cock by a rod so that
the act of opening or shutting the supply cock may also open or shut the air cock.
As variations of the above the tubes may be prolonged any distance and the ends

page_text: inserted in an oil vessel which takes the place of the bottom tank above mentioned.
In this case the valve before mentioned may be replaced by a stop-cock placed on
the oil tube and operated as to opening and shutting in a similar manner as the
valve before described.

An Improved Feed for Supplying Oil to Burners in Controlled
Quantities.
WILLIAM REYNOLDS, King Street, Coventry, Engineer,' LEONARD GETHIN ASTLEY,
Broadgate, Coventry, Oil Merchant, 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:-
The apparatus consists of two essential parts viz. the storage tank and the feed
tank and the object of the invention is to keep the oil always at the same level in
the feed tank whether the quantity drawn off is large or small and incidentally
to stop the supply of oil to the feed tank when the flow away ceases.
To effect this object we construct a storage tank of any size closed on all sides
so as to be air tight and oil tight and on the top side affix a cock through which it
may be filled with oil. On the bottom, outside the tank we affix a short tube with
a valve seating on its bottom edge. Inside this tube are two other tubes, one of
which passes through the bottom of the tank to a short distance of the top and the
other passes through the bottom and extends to about one inch into the tank.
These tubes are secured to the tank bottom with an air and oil tight joint,' but are
open at both ends. The long tube should not be less than three times the diameter
of the short tube.
A valve attached to a lever supported by a bracket or hinge is also affixed out-
side the bottom of the tank so that when pressed up the valve will close on the seat-
ing of the outside tube before mentioned and incidentally close the lower orifices
of the two tubes also mentioned which communicate with the inside of the tank.
On the line of the valve lever another tube is fixed which passes completely
through the tank from bottom to top and is secured to the bottom and top of the
tank in an air and oil tight manner as to its outside but is open throughout its
length inside. A wire or rod is affixed to the valve lever and passes into this tube
where it is attached to a spiral spring. Another wire or rod is attached to the other
end of the spiral spring and comes up through the top of the tube.
On the top of the tank the cock before mentioned has a bar secured to the key
or thumb piece of the cock with a handle at one end while the other end is
connected to the wire from the top of the spiral spring. We find it convenient to
make this connection by an angle piece and chain similar to the connection used in
bell hanging.
We will now suppose the cock to be closed fully. The spring will be at rest and
the valve dropped away from its seating leaving the tubes which open into the
inside of the tank uncovered. On proceeding to open the cock the first movement
of the handle will pull up the valve lever into its seating, and so close the orifices
of the inside tubes. As the handle is further raised to complete the opening of the
cock the spiral spring will give and allow for the extra pull on the valve lever.
The feed tank is a vessel open at the top, and we find it convenient to secure the

page_text: storage tank over the feed tank so as to form a cover to it. The feed tank is sup-
plied with one or more outlet pipes to convey the oil to the burners and also a waste
pipe fixed with its orifice slightly above the feed level of the oil so that in case of
failure in the feeding control the waste oil may be conveyed away and overflow
avoided.
To operate the mechanism, the handle is turned up to open the cock. The first
movement of the handle before the cock is sufficiently open to admit air into the
tank, will close the bottom valve. Oil is then poured in to fill the storage tank
and the cock closed. The action of closing the cock will free the valve and oil
will flow out of the short tube and be replaced by air flowing in through the long
tube. When the oil in the feed tank rises high enough to cover the orifice of the
air tube the flow will cease.
It will be seen that in using this feed the burners to be supplied must all be on
one level. If different levels are necessary although each will require its own feed,
these may be connected by a supply pipe from the uppermost feed or from any
receptacle and can be filled by turning on the cocks as before described.
In order that our invention may be more clearly understood we have appended
a drawing of the improved feed.
A is the storage tank. B the feed tank with the storage tank resting on it. Cis
the cock for filling the tank, shewn in the drawing closed. E is the tube enclosing
the spring F which is connected to the handle H by the chains G and the angle
piece D. I is the air tube J the oil outlet enclosed in the short tube K. The
valve L is connected at M with the spring and hinges on the bracket N. O is
the feed pipe to burners and W the waste pipe.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1st. The improved oil feed consisting essentially of a storage and feed vessel
relying on the pressure of the air to regulate the supply of oil substantially as
described.
2nd. Connecting the closing valve with the feed cock in such a manner that the
cock cannot be opened without closing the outflow of oil.
3rd. The application to oil feeds of a waste pipe the orifice of which is above the
usual oil level.
