PROVISIONAL SPECIFICATION left by the said John Gustavus Rollins
at the Office of the Commissioners of Patents, with his Petition,
on the 4th December 1868.
I, JOHN GUSTAVUS ROLLINS, of Old Swan Wharf, Upper Thames
Street, in the City of London, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN NOZZLES FOR OIL CANS AND OTHER
VESSELS," a communication to me from abroad by Henry Page, of
Boston, in the State of Massachusetts, United States of America, to be
as follows:-

page_text: thin metal spun up into a screw, and apply a screw cap thereto made
in a somewhat similar manner; but instead of leaving the bottom of the
nozzle open to the can or other vessel, I fix a piece of thin metal or
other suitable material therein, which may be readily removed by a
knife or other suitable means when it is desired to pour out the contents
of the can or other vessel. The space enclosed between the bottom of
the nozzle and the screw cap or cover may have placed therein a paper
of directions or even advertisements, whilst a trade mark may be stamped
or otherwise indicated on the bottom of the nozzle. By these means
the can or other vessel is hermetically sealed for transport, whilst when
the bottom of the nozzle is removed the cap or cover forms a sufficiently
secure protection to the contents thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Gustavus Rollins in the Great Seal Patent.
Office on the 4th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GUSTAVUS ROLLINS, of Old Swan Wharf, Upper Thames Street, in the
City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of December, in the' year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Gustavus Rollins, Her special
licence that I, the said John Gustavus Rollins, my executors, adminis-
trators, and assigns, or such others as I, the said John Gustavus
Rollins, 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 Mau, an Invention for
"IMPROVEMENTS IN NOZZLES FOR OIL CANS AND OTHER VESSELS," a communi-
cation to me from abroad by Henry Page, of Boston, in the State of
Massachusetts, United States of America, upon the condition (amongst
others) that I, the said John Gustavus Rollins, my executors or adminis
trators, by an instrument in writing under my, or their, or one of their

page_text: hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, 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 John Gustavus Rollins, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, 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 nozzles for oil cans
and other vessels. For this purpose the nozzle is formed by preference
of thin metal spun up into a screw, and a screw cap is applied thereto
which is made in a somewhat similar manner; but instead of leaving
the bottom of the nozzle open to the can or other vessel, a piece of thin
metal is fixed at the bottom thereof, which may be readily removed by a
knife or other suitable means when it is desired to pour out the contents
of the can or other vessel.
And in order that the Invention may be more clearly 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 vertical section of a head of a can with a screw nozzle,
having the improvement applied thereto; Figure 2 is a vertical sectional
view, representing the nozzle with the improvement applied, before it
is attached to the can or vessel; Figure 3 is a vertical sectional view on
a larger scale, representing the joint between the nozzle and the can.
Similar letters of reference indicate corresponding parts in the several
Figures.
The principal objects of this Invention are to obtain absolute tightness
of the nozzle of the can or other vessel until it is desired to take out
the contents, to afford facility for its being opened without injury, and
to provide for the vessel being afterwards closed with a tolerable degree
of tightness
The Invention consists in hermetically sealing the bottom of the
nozzle by a plate of metal made separate from the nozzle, but soldered
with it to the can or vessel, such plate being made of such thickness

page_text: irrespective of the nozzle that, while it may be strong enough for the
protection of the contents of the vessel, it may when it is desired to
open the can or vessel be easily cut out with a pocket knife or other
simple cutting instrument without injuring the nozzle, and thereby
preventing the future closing of the vessel by a cap or stopper. When
the cap or stopper is put on or in the nozzle thus closed at the bottom
there is formed within the nozzle a box within which may be placed a
circular or paper of printed directions for the opening of the vessel, or
for the use of its contents, or anything else which it may be desirable to
insert.
This Invention, though applicable to nozzles other than screw
nozzles, is represented in the accompanying Drawing applied to a screw
nozzle A. This nozzle itself has nothing peculiar in its construction,
and is soldered to the head B of the can or other vessel around the
margin of a suitable hole a provided therein for the purpose of filling
the can or vessel, but before it is applied to the vessel it has attached
to its bottom the plate or diaphragm C, which constitutes the Invention.
This plate or diaphragm may be attached in various ways, but the most
convenient is to make it with a turned up rim c, c, as shown in Figure 2,
which will fit tightly over the bottom of the nozzle. The can or vessel
is filled through the opening a before the nozzle is soldered thereto. In
soldering on the nozzle to the vessel care must of course be taken that
the solder d is so applied that it entirely covers the rim c, c, and effects
the union of the nozzle itself to the vessel. It will be seen that when
the cap D is put on the nozzle, the latter being closed at the bottom
forms a closed box for the reception of any small article which it may
be desirable to place therein. When it is desired to open the vessel the
cap Dis taken off, and the plate or diaphragm C may be cut out with
a pocket knife or other instrument without in any degree injuring the
nozzle as is likely to be done in cutting out the closed top of a nozzle.
Instead of the plate or diaphragm C being attached to the nozzle before
the application of the latter to the can or vessel, it may be applied
to the hole in the head of the can or vessel separately from the
nozzle, and before the application of the nozzle thereto. The closed
bottom of the nozzle may have stamped upon it any trade mark or
device which would afford protection against the refilling of the vessel
with inferior material for the purpose of disposal as the original contents,
The plate C made in a separate piece from the nozzle has several

page_text: advantages over a bottom forming a portion of the nozzle itself, not the
least important of which is that it can be made of any thickness
irrespective of the nozzle, and hence made so thin as to provide for its
being easily cut out with a pocket knife, while the nozzle may be made
so stout that it will not be liable to injury. The nozzle and plate may
also be made of different metals.
Having thus described the nature of the said Invention, and the
manner in which the same is carried into effect, I would have it under-
stood that I do not confine myself to the precise details herein shown
and described; but what I claim and desire to secure by Letters Patent
is,―
First. The plate C made separate from the nozzle and can, in com.
bination with the nozzle and the can, substantially as and for the purpose
herein specified.
Second. The box formed within the nozzle by the closed bottom Cand
the cap or stopper, substantially as herein described.
In witness whereof, I, the said John Gustavus Rollins, have here-
unto set my hand and seal, this Thirty-first day of May, in
the year of our Lord One thousand eight hundred and sixty-
nine.
