CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF PROVISIONAL SPECIFICATION
Year: 1856

page_text: LETTERS PATENT to Victor Jean Baptiste Mauban, of 39, Rue de
l'Echiquier, Paris, and 4, South Street, Finsbury, Lamp Manufacturer,
for the Invention of "CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF
PROVISIONAL SPECIFICATION left by the said Victor Jean Baptiste
Mauban at the Office of the Commissioners of Patents, with his Petition,
on the 2nd June 1856.
I, VICTOR JEAN BAPTISTE MAUBAN, of 39, Rue de l'Echiquier, Paris, and
4, South Street, Finsbury, Lamp Manufacturer, do hereby declare the nature
of
my said Invention for "CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF
CANS FOR HOLDING OIL AND OTHER LIQUIDS," to be as follows, that is to say: -
My improvements consist in constructing cans for holding oil and other
liquids so as to avoid the contents from being overturned or spilled, as usually
takes place with vessels of a similar kind now in use, especially when placed
in an inclined position. For this purpose the ingress and egress orifices of
the can are closed air-tight by means of two small valves, which are worked
by a spring set in the interior of the can. The spring serves to keep the
valves closed when the can is full of oil, and by pressing it down with a piston.
rod properly adjusted to the can and moved by the hand, the valves are made
to open when required to draw off the liquid.

by the said Victor Jean Baptiste Mauban in the Great Seal Patent
Office on the 1st December 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VICTOR
JEAN BAPTISTE MAUBAN, of 39, Rue de l'Echiquier, Paris, and 4, South
Street, Finsbury, London, Lamp Manufacturer, send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of June, in the year of our Lord One
thousand eight hundred and fifty-six, in the nineteenth year of Her reign, did,
for Herself, Her Heirs and successors, give and grant unto me, the said
Victor Jean Baptiste Mauban, Her special license that I, the said Victor
Jean Baptiste Mauban, my executors, administrators, and assigns, or such
others as I, the said Victor Jean Baptiste Mauban, my executors, adminis-
trators, 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 "CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF CANS FOR
HOLDING OIL AND OTHER LIQUIDS," upon the condition (amongst others) that I
the said Victor Jean Baptiste Mauban, by an instrument in writing under my
hand and seal, 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
anonths next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Victor Jean Baptiste Mauban, do
hereby declare the nature of my 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, reference being had to the Drawing
hereunto annexed, and to the figures and letters marked thereon, that is to
say:-
The improvements consist in applying to the ingress or egress orifices of
cans for holding oil a valve or stopper worked by a rod, and kept closed by
a spring, thereby enabling the can to be placed at any inclination without
exposing the contents to be overturned and waste. These cans are adapted
for oiling locomotives and other machinery.
Having thus described the nature of my Invention, I will now proceed to
describe and shew the mode of carrying the same into effect, reference being

page_text: had to the Drawing hereunto annexed, in which the same letters refer to
similar parts.
Figures 1, 2, 3, shew sections of different forms of the improved oil cans.
In Figure 1, E is the can, on the side of which is fixed a guide B for the
rod A, provided with a milled cap A'; the opposite end of the rod A is
attached to the bell-crank lever C, working on the fulcrum D, soldered or
otherwise fixed to the sides of the can; the other extremity of the lever is
fitted to the vertical rod F, working in a suitable guide, to which rod is
attached the valve or stopper G, composed of caoutchouc or other flexible
material, which is made to fit tight by the opening I by means of a spring.
The oil is poured into the vessel by removing the screw cap J, fitted with
a tube or spout I. By pressing on the cap A¹ the valve G is withdrawn and
the oil passes out through the spout. Figures 2 and 3 are modifications of
the improved oil can. The oil is supplied to the vessel through an opening
provided with a screw cap C¹. Figure 4 is a section of a tea-pot with the
valve applied to an opening H in the spout. Figure 5 represents the same
arrangement applied to a coffee-pot.
Ilaving now described the nature of my said Invention, and in what
manner the same may be carried into effect, I would have it understood that
what I claim is,―
First, the mode of constructing oil cans for preventing the escape of the
oil when overturned, as herein-before described.
Secondly, the method of constructing vessels for making infusions to
prevent the injurious effects of the atmosphere on the liquid they contain, as
herein-before described.
In witness whereof, I, the said Victor Jean Baptiste Mauban, have
hereunto set my hand and seal, this Twenty-ninth day of November,
in the year of our Lord One thousand eight hundred and fifty-six.
