AN IMPROVED VESSEL OR CAN FOR OILING MACHINERY
Year: 1855

page_text: LETTERS PATENT to Ebenezer Daggett Draper and George Draper, of
the State of Massachusetts, of the United States of America, for the
Invention of," AN IMPROVED VESSEL OR CAN FOR OILING MACHINERY."—
A communication.
Sealed the 25th January 1856, and dated the 18th August 1855.
PROVISIONAL SPECIFICATION left by the said Ebenezer Daggett Draper
and George Draper at the Office of the Commissioners of Patents, with
their Petition, on the 18th August 1855.
We, EBENEZER DAGGETT DRAPER and GEORGE DRAPER, of the State of
Massachusetts, of the United States of America, do hereby declare the nature
of the Invention for "AN IMPROVED VESSEL OR CAN FOR OILING MACHINERY" to
be as follows; it being represented in the accompanying Drawing, which
denotes a vertical and central section of it:-
The nature of the Invention consists in combining and arranging with an
oil vessel of peculiar construction, as herein-after described, a chamber and two
pipes, one of which leads into and the other out of said chamber.
In the Drawing, A is an oil can, vessel, or reservoir, provided at its upper
part with a long discharge tube c, which is surrounded at or near its lower end
Within such vessel A and near its upper part is arranged
A pipe C leads out of the trough 6 and into the vessel or
with a trough b.
a close vessel B.

page_text: chamber B, and terminates and opens near the bottom of said vessel B.
Another pipe D leads out of the bottom of the chamber B, and opens into
the oil reservoir A near its bottom, and is inclined towards the side of the
said reservoir, as seen in the Drawing. When the reservoir A is supplied
with oil or other liquid and is inverted, such oil or liquid will flow through the
pipe c and out of it, and such oil or liquid as may run down on the outer
surface of the tube c when it is restored to an upright position will find its
way into the trough b; from thence it will flow down the pipe C into the
chamber B, and from thence into and through the pipe D and into the reser-
voir A. When oil in the vessel A does not reach the bottom of the chamber
B, and we invert the oil vessel, no oil can escape from the chamber B into
the pipe C, but such oil as may be in the chamber B will remain in such
chamber. By means of the pipe D, the chamber B, and pipe C, the air when
the can is inverted passes into the reservoir A, so as to permit the oil to freely
flow out of the pipe c without material obstruction from the pressure of the
atmosphere. The capacity of the tube D should be less than that of the
chamber B. On supplying the oil can with oil, the fluid should not be allowed
to rise in the chamber A above the level of the bottom of the chamber B.
We do not claim the combination of the trough b with the pipe c and the
reservoir A; but we claim the combination and arrangement of the chamber B,
and its pipes C, D, with the oil reservoir A, its trough b, and discharge pipe c,
combined substantially as described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ebenezer Daggett Draper and George Draper in the Great
Seal Patent Office on the 28th January 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EBENEZER
DAGGETT DRAPER and GEORGE DRAPER, of the State of Massachusetts, of the
United States of America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Пer Letters
Patent, bearing date the Thirteenth day of August, A.D. 1855, in the nine-
teenth year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Ebenezer Daggett Draper and George Draper, Her
special license that we, the said Ebenezer Daggett Draper and George Draper,
our executors, administrators, and assigns, or such,others as we, the said
Ebenezer Daggett Draper and George Draper, our executors, administrators,

page_text: 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 Inven-
tion of "AN IMPROVED VESSEL OR CAN FOR OILING MACHINERY," upon the
condition (amongst others) that we, the said Ebenezer Daggett Draper and
George Draper, by an instrument in writing under our 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 we, the said Ebenezer Daggett Draper and George
Draper, do hereby declare our said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement (that is to say):
The nature of our Invention consists in combining and arranging with an
oil vessel of a peculiar construction, as herein-after described, a chamber and
two pipes, one of which leads into and the other out of said chamber.
In the Drawing, A is an oil can, vessel, or reservoir, provided at its upper
part with a long discharge tube c, which is surrounded at or near its lower end
with a trough b. Within such vessel A and near its upper part is a close
vessel B. A pipe C leads out of the trough 6 and into the vessel or chamber
B, and terminates and opens near the bottom of the of said vessel B. Another
pipe D leads out of the bottom of the chamber B, and opens into the oil reser-
voir A near its bottom, and is inclined towards the side of the said reservoir,
as seen in the Drawing.
When the reservoir A is supplied with oil or other liquid and is inverted,
such oil or liquid will flow through the pipe c and out of it, and such oil
or liquid as may run down on the outer surface of the tube c when it is
restored to an upright position will find its way into the trough b; from
thence it will flow down the pipe C into the chamber B, and from thence into
and through the pipe D and into the reservoir A. When the oil in the vessel
A does not reach the bottom of the chamber B, and we invert the oil vessel,
no oil can escape from the chamber B into the pipe C, but such oil as may be
in the chamber B will remain in such chamber. By means of the pipe D,
the chamber B, and pipe C, the air when the can is inverted passes into the
reservoir A, so as to permit the oil to freely flow out of the pipe c without
material obstruction from the pressure of the atmosphere. The capacity of

page_text: the tube D should be less than that of the chamber B. On supplying the oil
can with oil, the fluid should not be allowed to rise in the chamber A above
the level of the bottom of the chamber B..
+
..We do not claim the combination of the trough b with the pipe c and the
reservoir. A; but we claim the combination and arrangement of the chamber B,
and its pipes C, D, with the oil reservoir A, its trough b, and discharge pipe c,
combined substantially as described.
"In testimony whereof, we have hereunto set our signature and seals,
this Fourteenth day of December, One thousand eight hundred and
fifty-five.
