Year: 1867

page_text: LETTERS PATENT to William Rigg, of Cannon Street, in the City of
London, for the Invention of "IMPROVEMENTS IN MEANS OR APPARATUS
EMPLOYED FOR SECURING OIL OR OTHER LIQUIDS IN CANS AND OTHER VESSELS,
WHICH IMPROVEMENTS ALSO FACILITATE THE DRAWING OFF OF SUCH LIQUIDS
FROM THE VESSELS IN WHICH THEY ARE CONTAINED."
Sealed the 26th July 1867, and dated the 6th February 1867.
PROVISIONAL SPECIFICATION left by the said William Rigg at the
Office of the Commissioners of Patents, with his Petition, on the 6th
February 1867.
I, WILLIAM RIGG, of Cannon Street, in the City of London, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MEANS OR
APPARATUS EMPLOYED FOR SECURING OIL OR OTHER LIQUIDS IN CANS AND OTHER
VESSELS, WHICH IMPROVEMENTS ALSO FACILITATE THE DRAWING OFF OF BUCH
LIQUIDS FROM THE VESSELS IN WHICH THEY ARE CONTAINED," to be as follows:-
The Invention has for its object improvements in means or apparatus
employed for securing oil or other liquids in cans and other vessels, which
improvements also facilitate the drawing off of such liquids from the vessels
in which they are contained. For this purpose a hole is cut in the top or
other suitable part of the can or other vessel in the ordinary manner, through
which hole the vessel is filled. The metal around the hole is depressed so as
to permit of a cap or cover being soldered therein flush with the outer surface
of the can or other vessel after the filling thereof. This cap or cover is
formed with a short descending tube closed at the bottom, and having a screw

page_text: thread therein, which cap or cover when soldered in position in the can or
other vessel firmly secures the contents thereof. When it is desired to empty
the can or other vessel of its contents a hole is made in the bottom of the cap
or cover and a suitable tap or tube is screwed therein, thereby preventing the
waste which is usually incurred in emptying such vessels. When the vessel is
emptied the tap or tube is removed, and may then be employed with other
vessels provided with similar caps or covers. Instead of forming a screw in
the cap or cover other means of securing the tap or tube thereto may be
employed, and if desired a screw plug or stopper may be employed to close
the opening. The tap or tube may if desired be provided with a cutter, in
order that when being screwed or otherwise secured to the sbort descending
tube of the cap or cover such cutter may remove the bottom of the short
descending tube, and thereby enable the contents of the vessel to be
drawn off.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Willian Rigg in the Great Seal Patent Office on the
6th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RIGG, of Cannon Street, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of February, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Rigg, Her special licence that I, the said William Rigg, my
executors, administrators, and assigns, or such others as I, the said William
Rigg, 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 MEANS OR
APPARATUS EMPLOYED FOR SECURING OIL OR OTHER LIQUIDS IN CANS AND OTHER
VESSELS, WHICH IMPROVEMENTS ALSO FACILITATE THE DRAWING OFF OF SUCH
LIQUIDS FROM THE VESSELS IN WHICH THEY ARE CONTAINED," upon the condition
(amongst others) that I, the said William Rigg, my executors or adminis-
trators, 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.

page_text: 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 William Rigg, 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 thereof, that is to say:-
The Invention has for its object improvements in means or apparatus
employed for securing oil or other liquids in cans and other vessels, which
improvements also facilitate the drawing off of such liquids from the vessels in
which they are contained. For this purpose a hole is cut in the top or other
suitable part of the can or other vessel in the ordinary manner, through
which hole the vessel is filled. The metal around the hole is depressed so as
to permit of a cap or cover being soldered therein flush with the outer surface
of the can or other vessel after the filling thereof; this cap or cover is formed
with a short descending tube, closed at the bottom and having a screw thread
therein, which cap or cover, when soldered in position in the can or other
vessel, firmly secures the contents thereof. When it is desired to empty the
can or other vessel of its contents a hole is made in the bottom of the cap or
cover, and a suitable tap or tube is screwed therein, thereby preventing the
waste which is usually incurred in emptying such vessels. When the vessel
is emptied the tap or tube is removed and may then be employed with other
vessels provided with similar caps or covers. Instead of forming a screw in
the cap or cover other means of securing the tap or tube thereto may be
employed, and, if desired, a screw plug or stopper may be employed to close
the opening. The tap or tube may, if desired, be provided with a cutter in
order that when being screwed or otherwise secured to the short descending
tube of the cap or cover such cutter may remove the bottom of the short
descending tube and thereby enable the contents of the vessel to be
drawn off.
And in order that my Invention may be more fully understood and readily
carried into effect I will proceed, aided by the accompanying Drawings,.
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan, and Figure 2 is a section of one corner of an oil can
having part of my improvements applied thereto.
a, a, is a portion of the top of the can in which a hole is cut, and around
which hole the metal is depressed or countersunk at a', as shewn, in order

page_text: that when the can has been filled through such hole the cap or cover 6 may
be soldered in such depression a¹ and be flush or thereabouts with the outer
surface of the can or other vessel. The cap or cover b it will be seen is
formed with a short descending tube 61, closed at the bottom &, in order that
when such cap or cover 6 has been soldered in position the contents of the
can or other vessel may be securely retained. In the short descending tube b¹
of the cap or cover 6 a screw thread is formed in order when it is desired to
empty the can or other vesssel of its contents to facilitate the attachment of a
tap c thereto, as shewn at Figure 3, or of a tube c*, as shewn at Figure 4, a
hole being either previously made in the bottom of the short descending tube b¹,
or such hole may be formed at the time of fixing the tap or tube therein by
means of a cutter c' applied to the tube or tap, as shewn at Figures 3 and 4,
Figure 5 being an end view of either the tap or tube shewing how the cutter
is applied; Figures 6 and 7 shew two views in which a screw plug or stopper d
is employed to secure the contents of the can or other vessel after a hole has
been formed in the bottom of the short tube b¹ and the tap or tube has been
removed therefrom.
Having thus described the nature of my Invention, and the best means
with which I am acquainted for carrying the same into effect, I would have
it understood that I do not confine myself to the precise details herein shewn
and described; but what I do claim is, the combined improvements, sub-
stantially as herein shewn and described.
In witness whereof, I, the said William Rigg, have hereunto set my
hand and seal, this Second day of August, in the year of our Lord
One thousand eight hundred and sixty-seven.
Witness,
FRED*. HARRIS,
Patent Agent,

Chancery Lane.
