PROVISIONAL SPECIFICATION.
Improvements in Oilcans.
I, ROBERT SIMPSON, of Heeley Mill, Sheffield in the County of York,
Manufacturer, do hereby declare the nature of my invention to be as follows:-
This invention relates to oilcans that are chiefly used for lubricating purposes, the
object being to construct a can to be used in places difficult of access, or above the
height of the can, or for any ordinary positions, or work, and also to prevent
the dropping of oil from the spout, after using the can.
I propose to fix inside the body of the can, a cylinder provided with a piston, and
otherwise constructed to act as a pump; it is fixed at an angle so that the projecting
end of the piston rod is conveniently situated to be pressed upon by the thumb of
the hand in which the can is held.
In the bottom end plate of the cylinder, I fix a clack valve which opens inwards
to admit oil, and closes when the piston rod is pressed down; the piston is forced
back to its original position by a suitable spring.
A short cylinder or tube open at both ends, is connected with the lower portion
of the pump, and also with the spout of the can, at its base, and conveys the oil
from the pump to the spout.
The end of this short tube nearest the spout and upon which the spout is secured,
is made with a number of slots cut through its substance and open at their
outer ends.
Inside the tube is a piston valve, which is held against a ring seating past the
inner ends of the before mentioned slots, by the action of a spring, but when
pressure is applied to the oil by the action of the pump, the valve is forced from its
seat, and passes the inner ends of the slots, permitting the oil to pass through the
said slots into the spout from which it is ejected by the continued pressure of the
pump, in a continuous or intermittent jet as desired.
When the thumb is removed, or pressure withdrawn from the pump, the piston
is forced to its original position, and the action of the oil being reversed the valve
in the tube is closed upon its seat, and the oil in the spont is drawn back a short
distance, and thus prevents a hanging drop, or surplus oil running down the spout,
ensuring cleanliness and avoiding waste.

Improvements in Oilcans.
1, ROBERT SIMPSON of Heeley Mill, Sheffield in the County of York,
Manufacturer 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:-
This invention relates to oil cans such as are chiefly used for applying oil for
lubricating purposes, or for filling lamps, the object being to construct a can, that
can be used in places difficult of access, and others that are above the height of the
body of the can, or for any ordinary positions, or purposes, and to prevent the
dropping of oil from the end of the spout after use.

page_text: I have illustrated my invention in the accompanying drawings, in which similar
letters of reference indicate like parts in any of the figures in which they may
occur.
Fig. 1, represents an ordinary oiling can with part removed to show interior.
Fig. 2, enlarged section of spout valve.
Fig. 3, filling cup in section."
In carrying out the invention, I fix inside the body of the can A, a cylinder or
tube B, provided with a piston C, and piston rod D, with button E.
The piston is raised by a spiral spring F, and a small valve G, of any suitable
construction is fixed at or near the bottom of the cylinder, the whole being
constructed to act as a pump, and arranged at a convenient angle so that
the button E, can be readily pressed down by the thumb of the hand in which the
can is held.
The valve opens inwards to admit oil into the cylinder from the body of
the can, and it closes when the piston is pressed down; when the pressure is with-
drawn the piston is forced back by the spring F, before mentioned.
A second cylinder or tube H, is connected with and opens into the cylinder B,
near its lower end, the other end being secured inside the spout I, as shown,
and a number of open end slots J, are cut through its substance to form oil
passages.
Inside the tube H, is a piston valve K, which is held against a ring seating L,
placed past the inner ends of the beforementioned slots J, by the action of a
spring M, to prevent the passage of oil, but when pressure is put upon the oil by
the action of the piston C, this valve K is forced open, and past the inner ends of
the slots J, thus permitting the oil to enter the slots and pass into the spout from
which it is ejected by the continued pressure of the piston C, in a continuous or
intermittent stream as desired.
When the thumb is removed from the button or knob E, and pressure is taken off
the piston C, it resumes its normal position, and in doing this, a certain amount of
suction is produced drawing back the oil in the spout and tubes, and closing the
piston valve K; this return action of the oil, prevents either a hanging drop upon
the end of the spout, or surplus oil running down the spout, avoiding waste and
ensuring cleanliness.
Although I have shown the invention as applied to an ordinary pattern
of oil can, I wish it to be clearly understood that it may be applied to the
long tubular shaped cans, and to other patterns by slightly modifying the
construction.
To enable the can to be filled without any loss of oil, and without the use of a
detachable stopper or screw, I make a cup N, through the centre of which I fix
a short pipe O, through which I make one or more holes Q at the bottom of the
cup. Inside this short pipe I fit another pipe, closed at the top by a button P, and
also perforated to correspond with the outer pipe.
The two pipes or tubes may be connected by slightly enlarging the inside pipe at
its lower end or by other like means, but always so that the inner pipe may be
turned round by means of the button so as to open or close the holes to permit oil to
pass through when required to the interior.
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. An oil can of any desired pattern having a cylinder B, with piston C, piston
rod D, and valve G; the said cylinder being connected with and opening into a
second cylinder H, provided with a spring piston valve K, and having its end,
(where it is secured inside the spout) made with open end slots J, to form passages
for the oil, to pass under the valve K, when moved from its seat, substantially as
hereinbefore described and illustrated.

page_text: 2. In an oil can, the combination with a spring piston pump of any construction,
of a piston valve to fit against a ring scating, and having oil ways for the passage of
oil formed by cutting out slots J, in the valve cylinder, substantially as hereinbefore
described and shown.
