I JOHN ARTHUR HARRISON of Kensington Works Kensington Street Birmingham
in the County of Warwick Mechanic do hereby declare the nature of this invention to
be as follows:-
On the top of the pipe or stem of the lubricating can, I screw a small worn for
the purpose of screwing on the cap hereinafter described. The top of the pipe or
stem is slightly hollowed out, forming a little cup, to allow a small metal hall or other
suitable shaped piece of metal to rest in. The cap to place on the top of the pipe or
stem, is also hollowed out to fit on the top of the ball and pipe or stem, and a small
slot or groove is made on each side of the cap inside it, to allow the oil to run into,
for the purpose of lubricating. The bottom part of the cap, has a worm screwed
inside it, to screw on the top of the pipe or stem. My invention is performed and
fitted together as follows:-The ball, or other suitable shaped piece of metal, is placed
in the cup at the top of the pipe or stem, the cap is then screwed down on to the ball,
and the pipe or stem, which causes the ball to completely stop up the hole in the cup of
the pipe or stem, a sinall stop or shoulder is soldered or closed on to the pipe or stem,
in such a manner as to allow the cap to be turned round, sufficiently to loosen the
ball, and also to prevent the cap from being screwed off, the top of the pipe or stem,
and stopping the ball from being lost. When the lubricating can is required for
use, the cap is turned round, and by means of the worm in the cap and on the pipe or
stem, is raised up, releasing the ball, which falls into the cap, leaving the oil a free
passage to run into the slot or groove at each side of the cap, and from them out
through the hole in the top of the cap. When the lubricating can is not required for
ase, the cap is screwed down on to the top of the ball, forcing it down into the cap
of the pipe or stem, completely closing up the hole in it, and effectually keeps the oil
from running out of the can. I can perform my invention by substituting for the
ball above mentioned, a piece of metal, either in the shape of a cone or half ball, or
any other suitable shape, either fixed inside the cap, or to rest in the cup of the pipe
or stem, or by means of a flat surface, inside the cap, having a hole out of the centre,
and a flat surface on the top of the pipe or stem, instead of the cup, also having a
hole out of the centre, the cap is screwed on in the same manner as above described.

page_text: When the can is required to be used, the cap is turned a little way round, the hole in
the cap, fitting over the hole in the pipe or stem, leaving a free passage for the oil.
When the can is not required, the cap is turned in the opposite direction, the flat
surface of the cap, passing over the hole in the flat surface of the pipe or stem,
completely stopping it up, and preventing any flow of oil. A small stop or shoulder,
is soldered or closed on to the pipe or stem, to prevent the cap from being turned
too far, over the hole in the pipe or stem, and also to prevent the cap from being
screwed off. My invention can if required, be placed either midway, or at the bottom
of the pipe or stem.
My invention does away with all loose caps, has no springs levers, or taps to get
out of order and is very simple, cleanly, and effectual in its action.

page_text: I JOHN ARTHUR HARRISON of Kensington Works Kensington Street Birmingham
in the County of Warwick, Mechanic, 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 :-
On the top of the pipe or stem of the lubricating can I screw a small worm for
the purpose of screwing on the cap hereinafter described. The top of the pipe or
stem is slightly hollowed out forming a little cup to allow a small metal ball or other
suitable shaped piece of metal to rest in. The cap to place on the top of the pipe or
stem is also hollowed out to fit on the top of the ball and a small slot or groove is
made on each side of the cap inside it to allow the oil to run into the pipe or stem of
the cap for the purpose of lubricating. The bottom part of the cap has a worm
screwed inside it to screw on the top of the pipe or stem of the can. My invention is
performed and fitted together as follows. The ball or other suitable shaped piece of
metal is placed in the cup at the top of the pipe or stem the cap is then screwed
down on to the ball and the pipe or stem which causes the ball to completely stop up
the hole in the cup of the pipe or stem, a small stop or shoulder is soldered or closed
on to the pipe or stem in such a manner as to allow the cap to be turned round
sufficiently to loosen the ball and also to prevent the cap from being screwed off the

can is required for use the cap is turned round and by means of the screw worm in
the cap and on the pipe or stem is raised up releasing the ball which falls into the cap
leaving the oil a free passage to run into the slot or groove at each side of the cap
and from them out through the pipe or stem of the cap. When the lubricating can
is not required for use the cap is screwed down on to the top of the ball forcing it
down into the cup of the pipe or stem completely closing up the hole in it and
effectually keeps the oil from running out of the can. In order to prevent any oil
which may be left in the pipe or stem of the cap from running out when the lubri-
cating can is not required for use I fix a small wire rod on to the ball (or other
shaped piece of metal) which rod passes up the the pipe or stem of the cap. There is
also a small coil spring placed on the rod above the ball which spring bears
against the bottom part of the inside of the cap. When the can is being used
the spring forces the ball with the rod attached to it out of the ball
of the cap but is not sufficiently strong to make the ball bear against the cup of
the pipe or stem leaving a free passage for the oil to run into the groove
as above described. When the can is not required the cap is screwed down as
before described and the top of the rod completely closes up the top of the pipe or
stem of the cap preventing any oil which may be left in it from running out. I can
perform my invention by substituting for the ball above mentioned a piece of meta!

page_text: either in the shape of a cone or half ball or any other suitable shaped piece of metal
either fixed inside the cap or to rest in the cup of the pipe or stom or instead of any
hall or other shaped piece of metal by closing the top of the pipe or stem and
piercing a hole through it just below the top the cap is the same as above described
and is screwed on as above described. When the can is in use the cap is turned round
and the oil runs through the hole into the grooves and so out through the pipe. or stem
of the cap.
When not in use the cap is screwed down and closes the hole in the pipe
or stem.
I will now proceed to describe the same with reference to the accompanying
drawings. Fig. 1 shows the can fitted together. Fig. 2 shows a section of the cap
with the ball rod and spring in position together with the top of the pipe or stem of
the oil can. Fig. 3 shows the same parts when the can is in use. Fig. 4 shows the
cap with the ball in position without the rod and spring. Fig. 5 shows the invention
as performed without the ball by means of a hole in the pipe or stem.
When the can is in use the cap (a Fig. 3) is turned round and raised by means of
the screw worm the spring on the rod (b) forcing it and the ball (c) out of the cap:
When the can is pressed the oil is forced out through the pipe or stem (d) round the
ball into the grooves (e) and thence into the pipe or stem out of the cap and out
through the top. When the can is not required the cap (a Fig. 2) is screwed down
forcing the ball (c) on to the top of the pipe or stem (d) the rod (6) being at the same
time forced to the top of the pipe or stem of the cap preventing any oil from
running out. In the case of Fig. 4 when the cap (f) is screwed round and raised
the ball (g) falls into the cap and the oil runs round it into the grooves and so out
through the pipe or stem of the cap, when not in use the cap is turned down and
forces the ball on to the top of the pipe or stem completely closing up the hole in the
pipe or stem and preventing any oil from running out. In the case of Fig. 5 when
the cap (h) is screwed round and raised & the can pressed the oil is forced through
the hole in the top of the pipe or stem into the grooves and thence out through the
top.
I do not confine myself to any particular shape or form of the cap or any of the
various parts as above described.
Having now particularly described the nature of my invention and the manner
in which the same is performed I declare that what I claim is
The grooved and screwed cap, the ball (or other suitable shaped piece of metal) the
ball rod & spring with the pipe and stem either with the cup or with the hole pierced
as above described and the mode in which the same is made and fitted together.
It has no loose caps levers or taps to get out of order and is very cleanly and
effectual in its action.
