*Improvements in Oil Cans.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, trading as
H. Miller and Company, of Miller Street, Aston, near the City of Birmingham,
Manufacturers do hereby declare the nature of this invention to be as follows:-
Usually the pipes or the delivery spouts of oil cans are made of a given length,
and incapable of extension or elongation, which is a disadvantage, when out-of-the-
way parts of machinery or articles require to be lubricated.
Thus, in lubricating the bearings of cycle work, it is necessary for the hand of
the person supplying the necessary lubricant, to pass the same through the spokes
of the wheel, or through any gaps which admit of accessibility.
Our invention consists in making the pipes or spouts of oil cans extensible, and in
sections, so that the same admits of being elongated or contracted, so that
inaccessible parts to be lubricated, are readily got at, by passing or forcing the oil
to a distance, through the prolonged and delivery part.
In carrying out our invention, we will first describe it in connection with a cycle
oil can, with a two-sectioned pipe or spout, and with the prolonging or extensible
part, working telescopically within the other and fixed part, which is of the usual
construction.
Thus; we take an oil can, having an ordinary pipe or spout, and we provide the
outer end of the same, with a gland and stuffing box, and through which gland, and
down the inside of the pipe or spont as aforesaid, an extensible one is fitted, and
works within it telescopically, so that by pulling out the extensible section, the
length of the delivery part is prolonged additionally to that extent.
The gland and stuffing box, is for the purpose of preventing the escape of oil, at
the junction of the extensible section, and that of the other wherein it works.
The said gland of the stuffing box; may consist of cork, fine hemp, or other like
substances, applicable for the making of a grease-tight joint.
The inner end of the fixed pipe, screws into the edge of the body of the oil
chamber, as is usual, whilst the extensible section part, is fitted at its fore part with
a cap, carrying a needle as usual, within its mouth end, for removing dirt
accumulations or foreign matters from the contracted nozzle entrance to the pipe
or spout.
Or the cap, which covers the nozzle, may be screwed internally at its back
end, so as to take upon the front part of the covering of the stuffing box, at
the termination of the fixed pipe, while the extensible pipe, is prevented from
being withdrawn, by a stop or collar at its inner end.
When out of use, the extensible pipe section of the pipe or spout, is shut up,
or passed within the stationary part, whose screw has an inner extension tube
directed into the interior of the oil chamber.
Instead of making the said pipe in two sections, the same may be made into
three or more, working telescopically one within the other, or one over the other,
and with the junctions of the said tubular sections, provided with stuffing boxes
or other means, for making oil-tight joints.

Improvements in Oil Cans.
We, CHARLES ALBERT MILLER and FREDERICK JOHN MILLER, trading as
H. Miller and Company, of Miller Street, Aston, near the City of Birmingham,
Manufacturers 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 :-
Usually the pipes or the delivery spouts of oil cans are made of a given length,
and incapable of distension or elongation, which is a disadvantage when out-of-the-
way parts of machinery or articles require to be lubricated.
Thus, in lubricating the bearings of cycles with ordinary oil cans, it is necessary
for the hand of the person supplying the lubricant to pass the oil can through the
spokes of the wheel, or through any gaps which admit of accessibility.
Our invention consists in making the pipes or spouts of oil cans extensible, and
in sections, so that the same admits of being elongated or contracted, so that
inaccessible to be lubricated are readily got at, by passing or forcing the oil to a
distance through the prolonged and delivery parts.
In carrying out our invention, we will first describe it in connection with a cycle
oil can, with a two sectioned pipe or spout, and with the prolonging or extensible
part, working telescopically within the other and fixed part, which is of the usual
construction.
Thus, we take an oil can, having an ordinary pipe or spout, & we provide the
outer end of the same with a gland and stuffing box, and through which gland, and
down the inside of the pipe or spout as aforesaid, an extensible one is fitted and
works within it telescopically, so that by pulling out the extensible section, the
length of the delivery part is prolonged additionally to that extent.
The gland and stuffing box is for the purpose of preventing the escape of oil,
at the junction of the extensible section, and that of the one wherein it works.
The said gland of the stuffing box, may consist of cork, fine hemp, or other like
substances, applicable for the making of a grease-tight joint.
The inner end of the fixed pipe, screws into the edge of the body of the oil
chamber, as is usual, whilst the extensible section part, is fitted at its fore part
with a cap, carrying a needle as usual, within its mouth end, for removing dirt
accumulations or foreign matters from the contracted nozzle entrance to the pipe
or spout.
Or the cap, which covers the nozzle, may be screwed internally at its back end,
so as to take upon the front part of the covering of the stuffing box at the
termination of the stationary pipe, while the extensible pipe is prevented from
being withdrawn by a stop or collar at its inner end.
When out of use, the extensible pipe section of the pipe or spout is shut up, or
passed within the stationary part, whose screw may have an inner extension tube
directed into the interior of the oil chamber.
Instead of making the said pipe in two sections, the same may be made into
three or more, working telescopically one within the other, or one over the other,
and with the junctions of the said tubular sections provided with stuffing boxes, or
other means for making oil-tight joints.
Figure 1 of the accompanying drawing represents partly in vertical section,
and partly in elevation, an oil can, having a distending or elongating delivery pipe
or spout, constructed arranged and provided according to our invention.
The said extensible spout is shown closed, or with the same in the position which
it normally assumes when out of use, or for ordinary purposes.
It will be seen from the said section of the spout, that the same is composed of
two sections, a stationary part, and a movable and sliding part, and which latter
works telescopically within the former, whose inside bore is greater than the outside
diameter of the sliding spout part working within it.

page_text: Figure 2 represents the said oil can, with the stem part elongated or drawn out,.
showing the stuffing box located near the entrance to the stationary pipe part.
Figure 3 is a cross section upon the dotted lines A B, whilst
Figure 4 is the combined needle and cap, which takes within and upon the
nozzle end of the sliding and movable pipe.
In Figures 1 to 4, a is the oil can, and 6 is a stationary pipe, with the foot
end, of it, having an outside screwed neck 6, which takes into a socket or hole a³,
the holes of which are directed alightly into the interior of the can. The outer
end 6*, of the said stationary and attached pipe or spout, is chambered or socketed,
and also inside screwed, and adapted to receive the outside screwed collar part c³,
of a gland c, wherethrough the distensible and sliding pipe d, works. Contained.
within the cavity or stuffing box constituted by the said parts, is a packing e, also
wherethrough the said elongating pipe works, which has, at its inner end, a
collar d, which works within the bore 6, of the stationary pipe b, and comes
against an inside stop collar 6, at the junction of the said end with the stuffing box
part.
fis a washer, disposed between the foot of a pipe b, and the topside edge of the
bossed entrance to the can.
The nozzle of the distensible pipe is screwed, upon which the screwed cap g,.
takes, and into which, the needle i, passes.
Figure 5 represents an oil can, having a compound three sectioned spout, con-
structed according to a further form of our invention.
a is the oil can, with bossed entrance a². b is a stationary stem, with stuffing-
box parts b, c, cand e at one end, and foot parts 6, 68 and f. d is a distensible
pipe, with inner end having a stop collar d³, and the other end a stop d³, and a
packing d', and working within the bore of the first distensible pipe, is a second
movable pipe g, working telescopically within the bore of the said first named
sliding pipe d, and is prevented from being drawn out by a stop collar g³.
Having now particularly described and ascertained the nature of our said inven--
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First In an oil or lubricating can or vessel, making the pipes, or the delivery
spouts of the same in sections, working and sliding telescopically one within the
other, or one over the other, whereby the end section or sections admit of being
distended or elongated or shut up, according to the requirements of the user, sub-
stantially as described and set forth.
Secondly-In an oil can, with a single distensible section, working within a.
stationary section, and with the joints of the said sections fitted and provided with
stops and oil-tight devices, as described and set forth in Figures 1 to 3.
Thirdly-In an oil can, with two, three or more distensible sections, working
within a stationary section, and within or upon each other, and with the joints of
the said sections fitted and provided with stops and oil-tight devices, as described
and set forth in Figure 5.
