Improvements in Lubricating Cans.
I JOHN HARRISON of Kensington Works Kensington Street Birmingham in the
County of Warwick Manufacturer do hereby declare the nature of this invention
to be as follows:-
My invention consists of an improved method of closing and opening the mouth
of the spout of lubricating cans.
1 first drill a hole in the requisite position through the spout of the can and
through this hole I pass a pin and solder or otherwise fasten it so that the ends
project on each side of the spout and form arms for the spring after described to
turn upon. I next stamp or cut out of sheet steel or other metal a suitable shaped
piece for my purpose (and which I call the spring) the centre of which is stamped
into a cap having laterally projecting wings and the extreme ends of the sides
have a hole stamped out in each. The sides are then bent into a semi-elliptical
or bow shape so as to form a spring. The cap has a piece of leather or other
suitable material inserted in it to prevent the oil from leaking. I now pass the
two projecting arms of the pin on the spout through the holes in the ends of the
spring and then head such arms to prevent the sides springing off. The spout is
inserted in the lubricating can and it is then complete.
When the lubricating can is required for use the sides of the spring are pressed
such pressure raising the cap up from off the mouth of the spout and is then pushed
back leaving the mouth of the spout free for lubricating purposes. When the
lubricating can is not required the cap is raised up and pushed forward the
projecting wing on the cap slides over the top of the spout elongating the spring
till the cap reaches the top of the spout when the expansion of the elliptical sides
of the spring forces the cap down and holds it firmly on the top of the spout
preventing any leakage or flow of oil.
Or instead of the elliptical shaped spring I stamp or cut out of sheet steel or
other metal a straight piece having a cap and wing stamped at one end, the other
end for a certain distance being cut or split to form two sides, these sides are
then bent to form two coil springs, one of each of these springs are then fastened
on to one of each of the projecting arms of the pin on the spout of the lubricating
can. The spout is inserted in the lubricating can and the can is then complete.
When the can is required for use the cap is lifted up and forced back and held.
down by the coil springs leaving the mouth of the spout free for lubricating
purposes. When the can is not required the cap is raised up and pushed forward
the projecting wing on the cap slides over the top of the spout till the cap reaches
the top of the spout when the expansion of the coil springs forces the cap down
and holds it firmly on the top of the spout preventing any leakage or flow
of oil.
My invention does away with the employment of a screw valve or loose cap as
now commonly used or employed for the purposes of opening or closing the mouth
of the spout of lubricating cans is very simple in construction and not likely to
get out of order.

Improvements in Lubricating Cans.
I JOHN HARRISON of Kensington Works Kensington Street Birmingham in the
County of Warwick Manufacturer 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 :-
My invention consists of an improved method of opening and closing the mouth
of the spout of lubricating cans and is made and performed as follows:-
I first drill a hole in the requisite position through the spout of the can and
through this hole I pass a pin which I solder or otherwise fasten so that the ends
project on each side of the spout and form arms for the spring after described to
turn upon. I next stamp or cut out of sheet steel or other metal a suitable shaped
piece for my purpose (and which I call the spring) the centre of which is stamped
into a cap having laterally projecting wings and the extreme ends of the sides
have a hole stamped out in each. The sides are then bent into a semi-elliptical
or bow shape so as to form a spring. The cap has a piece of leather or other
suitable material inserted in it to prevent the oil from leaking. I now pass the
two projecting arms of the pin on the spout through the holes in the ends of the
spring and then head such arms to prevent the sides springing off. The spout is
inserted in the lubricating can and it is then complete.
When the lubricating can is required for use the sides of the spring are pressed
(such pressure elongates the spring and raises the cap up from off the top of the
spout) and is then pushed back leaving the mouth of the spout free for lubricating
purposes. When the lubricating can is not required the cap is lifted up and
pushed forward the projecting wing on the cap slides over the top of the spout
elongating the spring till the cap reaches the top of the spout when the expansion
of the elliptical sides of the spring forces the cap down and holds it firmly on the
top of the spout preventing any leakage or flow of oil.
Or instead of the elliptical shaped spring I stamp or cut out of sheet steel or
other metal a straight piece having a cap and wing stamped at one end, the other
end for a certain distance being cut or split to form two sides, these sides are then
bent to form two coil springs. One of each of these springs are then fastened on
to one of each of the projecting arms of the pin in the spout of the lubricating
can. The spont is inserted in the lubricating can and the can is then complete.
When the can is required for use the cap is lifted up and forced back and held
down by the coil springs, leaving the mouth of the spout free for lubricating
purposes. When the can is not required the cap is raised up and pushed forward
the projecting wing on the cap slides over the top of the spout till the cap reaches
the top of the spout when the expansion of the coil springs forces the cap down
and holds it firmly on the top of the spout preventing any leakage or flow
of oil.
In addition to either of the above methods I can perform my invention in the
following way.
Instead of bending the sides of the spring into a semi-elliptical or bow shape
as first described such sides are bent down at right angles to the cap and nearly
at the bottom of the sides a slot is cut out in each, and the extreme end of each
side is then bent up for the purpose of allowing the spring after described to bear
upon (this shape I call a slide cap). The ends of the pin in the spout (as above
described) are passed through the slots in the sides and then headed to prevent
the sides from coming off and at the same time allow the sides to slide up and down
on the spout. A small spring is then fastened on the screw at the bottom of the
spout in such a way that the ends of the spring bear on the turned up ends of the
sides of the slide cap.
The spout is then screwed into the lubricating can and it is then complete.

page_text: When the can is required for use the slide cap is pushed up from off the mouth
of the spout and the spring bearing down on the bottom ends forces the slide cap
down leaving the mouth of the spout free for lubricating. When the can is not
required for lubricating the slide cap is raised up and pushed forward, the wing
on the cap slides over the top of the spout till the cap reaches the top of the spout
when the pressure of the spring at the bottom forces the cap down and holds
it firmly on the mouth of the spout effectually preventing any leakage or flow
of oil.
The accompanying drawings show the shapes of the different springs, the
letters (a) show the spring (6) the cap and wings and (c) the pin passing through
the spout.
Figs. 1 and 2 are front and side views of the spring first described.
Fig. 3 shows the spring secondly described before the ends are coiled into
springs,
Fig. 4 showing a side view of the same fitted on to the spout.
Fig. 5 is a side view of the cap slide and spring last described, the slot being
shown at (d) and the turned up end and spring at (e).
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:
The opening and closing of the mouth of the spout of lubricating cans by
the methods and means of the springs caps and wings and slide cap as before
described.
