A New and Improved Form of Oil Can or Oiler, and Improvements
in Parts of Same.
I, WILLIAM GEORGE GASS of Atlas Foundry, Nelson Street Great Lever,
near Bolton, in the County of Lancaster, Engineer do hereby declare the nature of
this invention to be as follows:-
This invention relates to a new and improved form of oil can or oiler, and to
improvements in parts of same.
This oil can is so constructed that its centre of gravity will under ordinary
circumstances cause it to remain in an upright position, or if it is placed on one side
or with the spout down, it will become again upright and so prevent the waste of
oil which occurs in the ordinary form, when such a thing takes place.
$
The can or oiler consists of a hemispherically shaped dish' having preferably a
number of flattened or fluted sides converging to a common centre:-at this
common centre is formed a plane or concave surface which forms the base on which
the 'dish' stands.
A flat or convex 'cover' is placed on the 'dish' the joint being soldered, brazed,
or otherwise securely fastened, and from this 'cover' a 'spout' projects.
$
This spout' may be fastened to, or form part of the 'cover' of 'dish' or may be
screwed into 'cover' with a screw and ferrule in the ordinary way.
Inside the 'dish' at the bottom and fastened to or forming part of said 'dish,' is
a 'weight' of such size as to be capable, even when the 'dish' is full of oil, of
counterbalancing the weight of the 'spout' so as to cause the 'dish' to roll on one
of its flattened or fluted sides previously referred to, until it becomes upright, with
the position of the centre of gravity of the whole can at its lowest point.
An air valve of suitable form kept in place with a spring is placed in the 'cover'
of said 'dish' with the valve spindle' surmounted with a button, and which said
'spindle' projects through the 'cover' a sufficient distance to enable it to be easily
manipulated, the pipe by which the air is admitted terminating as near the bottom
of the 'dish' as possible.
.
A screwed cap or other suitable device is placed in the 'cover' for the purpose
of filling the 'dish' with oil.
It is proposed to make the 'dish' of one piece of sheet metal, pressed into shape
in suitable dies or to cast it of thin metal.
When the 'dish' is formed of sheet metal the 'weight' is fastened in place in
any suitable manner, but when the 'dish' is formed by casting the 'weight' is cast
in place at one operation.
It is proposed to form the 'spout' of a strip of sheet metal, coiled spirally on a
taper mandril, each coil overlapping the other, and securely soldered or brazed
while tightly coiled, the overlapping portion acting as a stiffening rib running
spirally the whole length of the spout."
:
The strip may have where extra strength is required a folded over portion or
rib, formed along one edge of the strip before coiling.
A tip, with a small hole in, being fastened at the extreme end of the 'spout' to
give it a finished appearance.

A New and Improved Form of Oil Can ar Oiler, and Improvements

'
I, WILLIAM GEORGE GASS of Atlas Foundry, Nelson Street, Great Lever
near Bolton in the County of Lancaster, Engineer do hereby declare the nature of
this invention and in what manner the same is to be penformed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to a new and improved form of oil can or oiler, hereinafter
referred to as the oil can-which is so constructed that its centre of gravity will
under ordinary circumstances cause it to remain upright; or if it is placed on its
side or knocked over will again resume an upright position, and prevent the waste
of oil which so often occurs with the ordinary form. It also includes a new and
novel method of constructing the spout of the said oil-can, by which it is strengthened
and made less liable to accidents which usually render the spout of similar oil cans.
useless.
Referring to the accompanying drawings-
Fig. 1. is a section of the oil-can.
Fig. 2. is a perspective view of the dish.
Fig. 3. is a perspective view of the cover.
Fig. 4. shews oil can when on its side and position of balance weight..
Fig. 5. is an outside view of the spout as made from a coil of ribbon.or strip of
metal.
Fig. 6. is an enlarged section of the strip or ribbon.
Figs. 7. 8. 9. are parts of the air-valve.
Throughout all the drawings similar letters apply to similar parts.
Referring to Fig. 1. the oil can consists of a hemispherically shaped dish B,
(shewn in detail Fig. 2) which is formed with a number of flat or fluted sides,
converging towards the base formed by a flat face L. The number of sides to this
dish B, is not arbitrary, the number shewn in Fig. 2-six-is a convenient one for
general use.
A cover C C is securely soldered, brazed, or otherwise fastened by its overlapping
edges to the dish B. This.cover CC may be either flat, or slightly concaved, so
that when the oil-can is inverted for use the oil may drain towards the spout A.
This spout A is provided at its larger end with a screwed ferule M, (preferably
made of brass) which is securely fastened to the said spout by soldering or other
convenient method. The ferule M screws into a corresponding socket piece N, also
preferably of brass, which is fastened to and forms part of the cover C C. The
joint between the two being made of a washer of leather or other suitable material
placed between them at O.
A brass tube D of small diameter, (Fig. 9), is secured to the cover CC and
terminates as near the bottom of the dish B as convenient. The bottom end of
this tube D is bevelled on its inner edge, so as to form a seating for the valve F,
(Fig. 7), on spindle E. This valve is formed of a ball of soft metal, soldered onto
the spindle E-This-spindle E has a flat cut on it as in section (Fig. 8) which
provides a passage for air when the valve is opened. A spring H keeps the valve
in place by pressing against the knob G. This knob is fastened to the spindle_by
soldering or screwing it on as found most desirable.
At the bottom of the dish B, and securely fastened to it is a weight K, preferably
of lead which acts as a counterpoise and causes the oil-can to remain upright.
This weight depends on the size of the oil can, but it is kept as light as possible in
order to make the oil can convenient for use.
The way in which the air valve Facts is as follows. When the can is inverted
and the air valve closed the oil can only come through the small outlet of the spout
at a very slow speed, but as the spindle E is depressed the air enters by the air

page_text: passage on side of spindle E and allows the oil to run out in a steady stream if
desired, the flow ceasing when the valve F is closed.
In the construction of the dish B it is desirable so that a smooth rolling action
of the oil-can will take place when it rights itself-that the sides of the dish B
form parts of a circle struck from a point which corresponds as nearly as possible
with the centre of the base of the spout as shewn by the dotted lines A-B
Fig. 1.
The flat sides of the dish B prevent any lateral rolling, and allow the oil-can to
immediately right itself. The length of the spout A is a matter which requires
proper proportioning-the length being determined experimentally to suit the size
of the dish it being made so that when the tip of the spout rests on the surface on
which the oil can rests the weight K is not past the vertical line e. f. Fig. 4.
In the construction of the spout A (Figs. 1 & 5) it is formed of a coil of metal
having one edge strengthened (Fig. 6). The whole being securely soldered
together to form a tube. This is best done while the strip or ribbon is coiled on
the taper mandril on which the spout has been formed. The thickened side then
forms a spiral rib which extends the full length of the tube and strengthens it.
An oil can of this improved shape can be made with the spout formed from one
piece of sheet metal in the ordinary way-the strengthened spout not being a
necessity but an improvement. I have shewn the sides of the dish B, as straight
but they can be made concave or convex, or a series of external ribs might be used
the hemispherical form with a flat base being still retained, the cover C C being
altered to suit these requirements-but the shape as shewn in the accompanying
drawings is the most convenient for general use. The dish is by preference made
from sheet metal, either by stamping or other means, or it might be made from
cast metal.
Although I have herein described the construction of my improved oil can as
specifically as possible, it must be understood that in order to meet different trade
requirements it may have to be altered in detail, but the main features will still be
retained. I am aware that a Patent has been granted for an oil can or oiler with
a weighted base, and that the self righting of an article by means of a weighted
base is an old one-therefore I do not claim that principle for the purpose
mentioned herein, but what I do claim and wish to protect by Letters
Patent is
First. In an oil can or oiler the combination of a hemispherically shaped dish B,
weighted at K, and constructed as described, having a flat or curved cover C C,
and a central spout A, with the air valve F, spindle E, tube D, spring H, and
knob G, all substantially as and for the purpose specified.
Second. In an oil can or oiler the combination of the hemispherically shaped
lish B, and cover C, with a spout A, formed from a ribbon of suitable metal having
ue edge thickened all substantially as and for the purpose specified.
Third. An oil can or oiler constructed substantially as specified.
Dated this 19th day of July 1892.
