Improvements in Oil-feeding Cans.
I GAVIN SIBBALD JONES of Clifton House, Send, Woking in the County of Surrey
Engineer do hereby declare the nature of this invention to be as follows:-
--
In an oil feeding can constructed in accordance with these improvements the
spout is fitted with a valve which when the can is upright remains open, and which when
the can is tilted for the purpose of oiling closes automatically by the action of gravity.
The valve is so situated that when the can is upright and charged with oil a small
portion of oil is contained in the spout between the valve and the spout outlet. When
the can is tilted for oiling purposes this portion of the oil flows out of the spout and
in the meantime the valve closes so as to prevent any further outflow of oil until the
can has been righted again, when the valve opens and allows a fresh charge of oil to
enter the spout. Sometimes the arrangement may be such that when the can is tilted
the valve either closes upon its seat or is prevented from doing so according to the
position into which the can is tilted. When the valve is prevented from closing the
oil flows from the spout continuously. Thus the same can may be employed for feeding
either in a continuous stream or in small regulated quantities. Means of adjustment
may be provided for regulating and varying the quantity of oil which will flow from
the spout when the can is tilted. The valve may be of "ball," "flap" or other convenient
type. Sometimes the valve may be dispensed with and the outflow of oil be restricted.
at each oiling operation by forming the can with a spout having a part inside the can
which exterds nearly to the back of the latter. When the can is upright and charged
with oil a portion of the oil will be inside the spout and when the can is tilted for oiling
purposes this portion will flow out and the supply from the body of the can be cut off
owing to the entrance to the spout being caused to protrude above the surface of the
oil by the tilting of the can.

Improvements in Oil-feeding Cans.
I, GAVIN SIBBALD JONES, late of Clifton House, Send, Woking, in the County of
Surrey, now of Nutcombe House, Weybridge, in the same County, 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 and the accompanying drawings:-
In an oil feeding can constructed in accordance with these improvements the spout
is fitted with a valvo which, when the can is upright, remains open; and which when
the can is tilted for the purpose of oiling closes automatically by the action of gravity.
The valve is so situated that when the can is upright and charged with oil a small
portion of oil is contained in the spout, between the valve and the spout outlet. When
the can is tilted for oiling purposes this portion of the oil flows out of the spout and in
the meantime the valve closes so as to prevent any further outflow of oil, until the can has
righted again; when the valve opens and allows a fresh charge of oil to enter the
spout. Sometimes the arrangement may be such that when the can is tilted the valve
either closes upon its sent, or is prevented from doing so according to the position into
which the can is tilted. When the valve is prevented from closing, the oil flows from
the spout continuously. Thus the same can may be employed for feeding oil either in a
continuous stream, or in small regulated quantities. Means of adjustment may be

page_text: provided for regulating and varying the quantity of oil, which will flow from the
spout when the can is tilted.
In the accompanying drawings Fig. A is an elevational view partly in section
representing an oil feeding can constructed in accordance with these improvements
for feeding the oil in limited quantities only; the can being shown in its upright
position and with the valve open. Fig. B is an enlarged sectional view of the spout
in a tilted position with the valve closed, a part of the can being shown by dotted
lines. In these views the spout comprises the tubular parts 1, 2, 3 screwed together
by a cap 4 as clearly shown. 5 is the valve formed as a ball and contained in the
part 1 which is somewhat contracted at its lower end to prevent the valve from
escaping therefrom. The lower end of part 2 is formed as a seat against which the
valve closes, when the can is tilted, as shown in Fig. B. 6 is a hole in the part 1
through which oil can flow into this part when the valve returns to the lower end
upon righting the can after it has been tilted. It will be seen that when the valve is
in its open position as shown in Fig. A a portion of oil is contained in the spout
between the valve and its seat at the lower end of part 2, and that when the can is
tilted as shown in Fig. B this portion of oil will flow out from the spout while the
valve is moving into its closed position, on arrival at which, the valve prevents any
further outflow from the can. As soon as the can is righted again, the valve returns
to the lower end of part 1, and a fresh charge of oil is taken into this part through
the hole 5, or it may partly flow in past the valve. Fig. is a view corresponding to
Fig. B and showing a modified arrangement according to which the extent of the
limited supplies of oil can be varied, and the supply can be made continuous at will.
Fig. D is a plan view of a portion of the spout. In this arrangement the exterior of
the part 2 is screwed and carries an adjustable nut 7 which forms the collar by the aid
of which the part 2 is held in position. According as this nut is adjusted nearer to,
or further from, the upper end of part 2, the valve seat stands nearer to or further
from the valve and a smaller or a larger charge of oil is contained between the seat
and the valve, and is emitted from the spout when the can is tilted. The part 1 is
formed with a hole 8 on either side each hole being large enough to entrap the valve
and to prevent it from running to its seat when the can is tilted if at the same time it
is turned partly over sideways. When the valve is thus entrapped a continuous feed
of oil can be delivered from the spout. If however the can is tilted straight forward
the valve will run past the two holes (without being entrapped by them) and close
against its scat, so as to interrupt the flow of oil. The movements of the valve 5 are
all produced by the action of gravity. It is evident that modifications may be made
in the details of the construction of the cans without departing from the principle of
my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The construction of an oil feeding can having a valve which closes by the action
of gravity when the can is tilted for the purpose of feeding the oil in limited quantities,
means being provided or not for varying the extent of these quantities substantially as
described and shown.
2. The construction of an oil feeding can having a valve which when the can is
titled either closes by the action of gravity, or is prevented from doing so for the
purpose of feeding the oil, either in limited quantities or in a continuous stream
means being provided or not for varying the extent of the limited quantities,
substantially as described and shown.
