Year: 1862

page_text: LETTERS PATENT to Joseph White, of 7, Trinity Street, Southwark, in the
County of Surrey, for the Invention of "IMPROVEMENTS IN LUBRICATING,
OR OIL CANS, OR OIL FEEDERS, AND IN THE MECHANICAL ARRANGEMENTS FOR
PROTEAM ..
"
Sealed the 8th July 1862, and dated the 11th January 1862.
PROVISIONAL SPECIFICATION left by the said Joseph White at the Office
of the Commissioners of Patents, with his Petition, on the 11th January
1862.
I, JOSEPH WHITE, of 7, Trinity Street, Southwark, in the County of
Surrey, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN LUBRICATING, OR OIL CANS, OR OIL FEEDERS, AND IN THE MECHANICAL
ARRANGEMENTS FOR REGULATING THE FLOW OF OIL THEREFROM," to be as
follows:-
My improvements relate primarily to a can in which the moveable top or
cover, instead of being screwed in or on to the same, is provided with a top
or cap fitting tightly in its place, and having inside the said cap leather, cork,
or other similar substance, so that by pushing the top into its place an air-
tight cover will be obtained. Inside this can I apply arrangements for
regulating the flow of oil from said can, and such arrangements consist in
this, viz., instead of the plunger tube heretofore used, having a small coiled
spring therein, with collars soldered or or secured at each end, together with
other troublesome constructions, I use a tube without any collars, and through
this descends a vertical plunger, which has a groove along it to act as an air
vent when pouring out oil; said plunger being provided with proper collar

page_text: and washer for closing from time to time the end of the tube through which
said plunger passes, the end of which plunger acts upon a lever inside the
aforesaid can; the said lever having its fulcrum in or on a cross bar or wire,
such fulcrum or turning point differing from the old arrangements, inasmuch
as instead of the cross bar or wire turning in small slight pieces of tube, the
said lever, has for its fulcrum a sound piece of tube, which is free to move on
the said fulcrum; or, the cross bar or wire turns in suitable bearings attached
either to the sides, the top, or bottom of the can. Or, instead of the arrange-
ments mentioned, the plunger might be arranged to act on the end of a bent
lever, with its fulcrum provided at the bottom of the can. The valve at the
other end of the bent lever for stopping the spout being weighted to close
easily. The spring or springs, which are not restricted to any particular form
or character, actuate the aforesaid lever, and may be applied above, below, or
in front, or at back of said fulcrum, or at the sides of the same, so as to act
by tension, or by pressure on the said lever; the end of the lever opposite
to the plunger being provided with a valve for stopping the entrance to the
spout, this valve being faced with a washer of leather, cork, or other suitable
substance, which is firmly secured to it by turning over the metal of the valve,
and clipping it tightly, or even by other suitable means, if preferred.
Another arrangement which could be adopted (but which I do not prefer
to use) for effecting the regulating of the flow of oil, is, by means of a lever,
which is withdrawn backwards, or propelled forwards by a trigger in the
place of the plunger, and thus closes the spout with a valve, or opens it again
as may be requisite.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph White in the Great Seal Patent Office on the 11th
July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
WHITE, of Trinity Street, Southwark, in the County of Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of January, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph White, Her special licence that I, the said Joseph White, my
executors, administrators, and assigns, or such others as I, the said Joseph

page_text: White, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
LUBRICATING, OR OIL CANS, OR OIL FEEDERS, AND IN THE MECHANICAL ARRANGE-
MENTS FOR REGULATING THE FLOW OF OIL THEREFROM," upon the condition
(amongst others) that I, the said Joseph White, my executors or admi-
nistrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Joseph White, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
(Part No. I.) My improvements relate to a can in which the moveable
top or cover is provided with a top lining of leather, cork, or other similar
substance, so that by temporarily securing the top in its place, an air-tight
and liquid-tight cover will be obtained. Inside this can I apply arrangements
for regulating the flow of oil from said can, and such arrangements consist
in this, instead of the plunger tube heretofore used, having a small coiled
spring therein, with collars soldered or secured at each end together with other
troublesome constructions, I use a tube without any collars, and through
this descends a vertical plunger, which has a groove along it to act as an air
vent; when pouring out oil, this plunger being provided with proper washers
for closing from time to time the end of the tube through which said plunger
passes, the end of which plunger acts directly or indirectly upon a lever'
inside the aforesaid can, the said lever having its fulcrum in or on a cross-
bar or wire, which fulcrum or turning point differs from the old arrangements
inasmuch as instead of the cross-bar or wire turning in small slight pieces
of tube, the fulcrum of said lever is either fixed or turns in such suitable
bearings as are hereafter described attached to the sides, to the top or the
bottom of the can. Or instead of the arrangements mentioned, the plunger
might be arranged to act on the end of a bent lever, which has its fulcrum
at the bottom or at the top of the can, the valve at the other end of the bent
lever for stopping the spout being weighted to close easily, and the spring or

page_text: springs, which are not restricted to any particular form or character, actuate
the aforesaid lever, and may be applied above, below, in front, or at back
of the said fulcrum, or even at the sides of the same, so as to act by tension
or by pressure on the said lever, the end of the lever opposite to the plunger
being provided with a valve for stopping the entrance to the spout, which
valve is faced with a washer of leather, cork, or other suitable substanco
firmly secured to it by turning over the metal of the valve or the sides, or
the ends, or both, and clipping tightly the same. An arrangement that I do
not prefer to use, but which could be adopted, if desired, would effect the
regulating of the flow of the oil by means of a lever withdrawn backwards or
propelled forwards by a trigger in the place of the plunger, thus closing the
spout with a valve, or opening it again as may be requisite. The handles
of my improved cans I prefer to make double or S shaped.
(Part No. II.) Having thus described the nature of the said Invention,
I will now describe in what manner the same is to be performed, wherein I
shall refer to the accompanying Drawings, by the words, figure, and letters
following, that is to say:-
Figure 1, side view of oil can, partly in section, shewing the disposition of
the mechanical arrangements herein-before described; Figure 2, plan view
shewing the oil can as placed bottom upwards, and the bottom removed;
Figure 3, detail view of the top of the plunger. Each of the said Figures
have the same letters of reference marked thereon in order to denote the same
parts wherever the same can be made to appear.
A, denotes the body of can; B, the cap or cover, which is made with
a recess at top, which recess is filled with leather, cork, felt, or other
similar material (6); C, the handle which is double or S-shaped, as
shewn, enabling the user to hold the can with more steadiness; D, plunger,
which passes through a tube e, e, and also through the washers f, f, the
upper washer being of leather, or other similar material and the lower
washer of metal of any kind. This plunger has an air groove g, running
from the top to the washer f. f. The lower end of the said plunger being
slotted or forked, holding the end of the lever E, which lever as aforesaid,
begins at the point near where the lower end of the plunger D is attached, and
a little beyond this is also attached the spiral spring F, the same being hooked
at its lower extremity, so as to hold to the lever E. The said lever E extending
to the mouth of a small tube G, communicating with the end of the spout H,
which has a valve I, which, consisting of a piece of tin or other suitable
metal or material, faced with a washer or pad of leather, cork, or other similar
material, secured to the metal by the latter being turned over at the edges, and

page_text: tightly clipping the said washer or pad. This valve cuts off the communication
between the body of the can A, and the spout H leaving the said spout full of
oil, which will not however flow from the spout till the said valve is removed
from contact with the mouth of the said tube G, that is, by pressure on the
plunger, which acts on the lever, to the end of which the said valve is secured.
It will be seen that the lever E has for its fulcrum a cross bar K of stout wire
or small tube, which fulcrum may be fixed by soldering or otherwise, or it may
turn in bearings of the kind shewn by the Drawings at L, L, which I term double
brackets, or instead of being of the precise form shewn by the Drawings, they
may be single brackets. These arrangements will insure that the oil shall
never issue from the can except when the plunger D is pressed upon, and
hereby the flow can always be regulated from a very small drop to full flow.
Although I have shewn the cap or cover as fitted on to its place, and secured
by a projection in the neck, to which the cover is fitted, taking into a bayonet
joint, slit in the cylindrical part of the cover, yet the same might be screwed or
otherwise temporarily secured in its place. And as before mentioned, the
spiral spring shewn by the Drawing, might be replaced by another kind of
spring, and instead of the plunger acting directly upon the end of the lever E,
it may
be sometimes desirable to make it act on a cross lever acting on said
lever E. Or the bent lever arrangement alluded to in the outset of this
Specification might be adopted. Or the relative positions of the parts varied
in any arrangement.
(Part No. III.) Having now particularly described and ascertained the
nature of the said Invention, and in what manner the same is to be per-
formed, I hereby declare that I claim the exclusive right and title to the
Invention, the nature and character whereof is set forth in the outset, (at the
part marked from Part No. I. to Part No. II.,) of this my Specification thereof.
In witness whereof, I, the said Joseph White, have hereunto set my hand
and seal, this Eleventh day of July, in the year of our Lord, One
thousand eight hundred and sixty-two.
Witness,
