I JAMES PEARSON 32 New Hall Lane Preston Lancashire Cotton Mill
Manager do hereby declare the nature of my invention for IMPROVEMENTS IN
OIL CANS WHEREBY THE PASSAGE OF OIL IS AUTOMATICALLY REGULATED
as follows:
" to be
In any portion of the spout of an Oil Can, is inserted a Chamber, as shewn in
section, in the Drawing herewith, having a small me as shewn at D.(Fig 1)
Enclosed in this chamber is a sphere, or Ball of (ass, Metal, (or any other
substance) marked P-This ball is only allowed to t verse from F to G-F and
G being stops, passing through diameter of the Chamb
When the Can is at rest (see Fig 1) the Ball res.s under the dome against
stop F-thus leaving the spout open to a considerable extent (see section on C. D.
Fig 1) When the Can is inverted for use the Ball falls to stop G (see Fig 2) The
diameter of the Chamber at this point being very little larger than the diameter of
the enclosed Ball-it at once determines & governs the quantity of Oil, which
shall pass it, for, delivery at the outlet at the end of the spout (see section on A B
Fig 2)-When the operation of Oiling is finished and the Can brought to rest-
the Ball again falls to F leaving the spout of Can open as before.
The advantage of this Automatic arrangement as above described, enables the
outlet at the end of spout to have an area, many times greater than the outlet at
present used-the outlet will not be so liable to become made up; but will be of
sufficient size to admit of an Instrument being inserted for clearing the obstruc-
tion-instead of the spout end being broken off (as is at present the case when
made up) until the orifice made is wastefully large-Thus this Invention gives
the advantage of a large, useful, orifice at the end of spout-whilst embracing
the economical advantages of an outlet of small area-when in its best possible
condition.
I claim for this Invention the perfect government of Oil used-its nonliability
to get out of order-that it cannot be tampered with that it is thoroughly
automatic simple & cheap-and that it will save a large percentage of Oil-now
wasted by the present existing Can.

I JAMES PEARSON of 32 New Hall Lane Preston in the County of Lancaster,
Cotton Mill Manager do hereby declare the nature of my invention for "IMPROVE-
MENTS IN OIL CANS WHEREBY THE PASSAGE OF OIL IS AUTOMATICALLY REGULATED
"
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 improvements in and applicable to oil cans for
lubricating purposes whereby the passage of oil from the can is automatically
regulated and the invention is applicable to ordinary oil cups or cans such as those
used in mills and workshops.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawing in which figure 1 represents an elevation
of an oil can or cup with my improvements shewn in section applied thereto, and
shewing the position of the can when not in use; figure 2 is a similar view to
figure 1 but shewing the position of the can when in use for lubricating; figures 3
and 4 are cross sections on lines A B and C D of figures 1 and 2 respectively.
Similar letters in all the figures represent similar parts.
'
In carrying out my invention, in any suitable part of the spout A of an oil can
but preferably at the end or tip of the spout I apply a taper tube or chamber C¹, C³;
within the tube C¹ C², I place a sphere or ball B of metal or other suitable material;
at suitable positions in the interior of the taper tube C1, C2, I fix stops F and G the
stop F consisting of a disc of perforated material and the stop G consisting of a
piece of wire inserted across the interior diameter of the tube C₁, C².
By this improved construction of spout or nozzle when the can is not in use the
ball B will rest against the perforated disc stop F and the spout will be open to a
considerable extent as shewn in figures 1 and 3; if however the can be tilted out
of the horizontal when required for use the ball B will roll towards the mouth of
the spout against the stop G, as shown in figures 2 and 4; the diameter of the
taper tube C1, C2, at this part being only slightly larger than the diameter of the
ball B the quantity of oil which is to be delivered at the outlet at the end of
the spout will be at once automatically determined and regulated the ball acting as
a valve; and when the operation of oiling is finished and the can is placed in a
horizontal position the ball B, will again roll against the stop F leaving the spout
of the can again open. The taper tube or tip can if required be screw-threaded
at S, for the purpose of allowing it to be attached to the spout A of the can. By
inserting the stop G nearer to or farther from the smallest end C2, of the taper tube
the can, can be made to deliver a smaller or larger quantity of oil according to
requirement.
Instead of having a perforated disc for the stop F as hereinbefore described and
shewn I sometimes employ a pin or stop of wire similar to the stop G.
The spout or nozzle constructed as hereinbefore described can be applied to the
spout of an ordinary oil can which should have the end with the small orifice cut
off for this purpose. Or as will be well understood the can may be formed with a
spout of this improved construction.

page_text: The advantages of the hereinbefore described construction of spout for oil cans
are as follows:-that it allows of having an orifice at the outlet end of the spout
of a much larger area than hitherto and the outlet consequently will not be so
liable to become made up or clogged as are the ordinary spouts after being in use
for a few days in mills and workshops. When the spouts 'become thus made up or
clogged the common practice has been to break off a portion of the spout in order
to obtain a flow of oil from the can thereby making the delivery orifice much
larger than is required and consequently a large quantity of oil was wasted each
time the can was used. This objection is entirely obviated by my improvements
as in case of grease or dirt entering the orifice it is of a size sufficient to admit of
an ordinary instrument being used to clear it. The maximum size of outlet orifice
is provided at the same time that a minimum supply of oil can be obtained and if
required a drop by drop delivery can be effected which is not practicable with oil
cans having ordinary spouts, or a fine flow of oil can be obtained.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In an oil can the employment of a ball or sphere contained within the spout of
the can and operating in such a manner as to regulate the supply of oil coming
from the can as herein before described.
2. In a spout for oil cans the combination of a conically shaped tube having stops
in its interior with a ball operating within the said tube and between the said
stops substantially as and for the purpose hereinbefore described and represented in
the accompanying drawing.
3. The improved spout for oil cans as hereinbefore described and represented in
the accompanying drawing.
4. An oil can having a spout constructed substantially as herein before described
and represented in the accompanying drawing.
