IMPROVEMENTS IN OIL CANS
Year: 1884

page_text: I GEORGE PICKFORD of Lee Street Oldham in the County of Lancaster Mule
Overlooker do hereby declare the nature of the said invention for "IMPROVEMENTS
IN OIL CANS to be as follows :—
The object of this invention is so to arrange and construct the spout of an oil-
can that the lubricating contents are prevented being wasted and the spout itself
is ensured being kept open and free from dirt or any obstruction-It also affords
greater facility for introducing the oil to the orifice of the bearing requiring
lubrication.
In carrying out my invention I apply a loose needle or rod in the spout
of the oil can-one end of which needle extends to the inside of the oil-can
whilst the other end is pointed and protrudes beyond the mouth of the spout
sufficiently far to form a guide in introducing the lubricant to the bearing as
aforesaid. This needle also prevents the entrance of dirt or other obstruction into
the spout and ensures the mouth being sufficiently open to allow the lubricant to
pass when the oil-can is in use. By means of this needle the flow of the lubricant
is also rendered constant and regular whilst the quantity supplied is regulated by
the thickness of the said needle as compared with the diameter of the orifice-a
suitable projection formed on the needle serves to prevent its withdrawal from
the spout.

page_text: I, GEORGE PICKFORD, of Lee Street, Oldham, in the County of Lancaster, Mule
Overlooker, do hereby declare the nature of my Invention for "IMPROVEMENTS
IN OIL CANS" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-—
The object of this invention is so to arrange and construct the spout of an oil
can that the lubricating contents are prevented being wasted and the spout itself.
is ensured being kept open and free from dirt or any obstruction. It also affords
greater facility for introducing the oil to the orifice of the bearing requiring
lubrication.
On the accompanying drawing Fig. 1 represents a sectional view and, Fig., 2 an
exterior view of a roller oil can embracing my improvements.
In carrying out my invention I apply a loose needle or rod a in the spout b' of
the oil can one end of which needle extends to the inside of the oil can whilst the
other end is pointed and protrudes beyond the mouth of the spout sufficiently far
to form a guide in introducing the lubricant to the bearing as aforesaid. The oil
proceeding from the mouth of the spout b is attracted to this needle a flowing
gracefully down the same to the point, and from thence is transferred by the
merest touch to the parts of machinery requiring lubrication. This needle also
prevents the entrance of dirt or other obstruction into the spout and ensures the
mouth being sufficiently open to allow the lubricant to pass when the oil can is in
use. By means of this needle the flow of the lubricant is also rendered continuous
and regular whilst the quantity supplied is regulated by the thickness of the said
needle as compared with the diameter of the orifice c. Suitable projections d
formed on the needle c serve to act as stops to prevent the withdrawal of the
needle from the spout and hence render it impossible for any one to tamper with
the spout or flow of the lubricant. The chamber e also enables the oil to travel
more quickly to the end of the spout (before commencing oiling) than would be
the case if the spout was throughout of one and the same internal diameter or
fitted closely to the needle-thus avoiding the inconvenience and loss of time in
having to wait so long before the oil reaches or issues from the end of the spout.
fand g'are air-tubes to permit the entrance of air and which aro isolated froin
each other as illustrated to prevent the possibility of the escape of the lubricant-
this however is not an essential feature of my invention.
·
By means of this roller oil can the operator can oil the bearings of rollers with
certainty and without the risk of oil getting on to the flannel or leather covering
of the rollers.
Fig. 3 represents in an exterior view partly in section my improvements applied
to a Kettle Oil Can which only differs from Figs. 1 and 2 in its shape and in the
base of the spout h extending through to the inside and being there perforated
with holes i and stopped up or closed at its extremity to receive the end thrust of

page_text: the needle j. The action in this modification is precisely the same as in Figs 1
and 2. These improvements are equally applicable to all classes of Oil Cans.
Having thus particularly described and ascertained the nature of this my
said Invention I declare that what I claim is
The use and application to the spout of oil-cans of a needle or rod with stops.
working in a cavity or chamber substantially as and for the purpose hereinbefore
described and illustrated on the accompanying drawing.
