AN IMPROVED PUMP
Year: 1856

page_text: LETTERS PATENT to Louis Adolphe Faure, Mechanician, of Paris, in
the Empire of France, and of 45, Essex Street, Strand, London, for
the Invention of "AN IMPROVED PUMP."
Sealed the 28th April 1857, and dated the 29th October 1856.
PROVISIONAL SPECIFICATION left by the said Louis Adolphe Faure at
the Office of the Commissioners of Patents, with his Petition, on the
29th October 1856.
I, LOUIS ADOLPHE FAURE, Mechanician, of Paris, in the Empire of France,
and of 45, Essex Street, Strand, London, do hereby declare the nature of the
said Invention for "AN IMPROVED PUMP," to be as follows:-
This pump is a double-acting one, and is placed inside and eccentrically of
an air chamber, and is provided with four valves, all of which are placed at
or near the bottom of the pump, and in the centre of the air chamber. Two
of these valves (the inlet valves) are placed in the inlet pipe, which is a little
below the bottom plate of the air chamber, and the other two, which are the
discharge valves, are placed on the bottom plate of the air chamber above, but
between the inlet valves. A partition between the bottom plate and the inlet
pipe divides one inlet & one discharge valve from the others. The discharge
pipe is placed on the side of the air chamber. The bottom of the pump
barrel is in immediate connexion with one set of valves, and the top of the
pump barrel is connected to the other set of valves by a tube or pipe, fastened
to the top and bottom plate of the air chamber, a passage being made in the
upper plate for the water to pass to and from the upper part of the piston.
By removing the inlet pipe all the valves are immediately brought to view.
The piston of the pump may receive its motion in any well known manner.

page_text: The air chamber, the pump barrel, and the tube or pipe, which connects the
upper part of the pump with one set of valves, are merely cylindrical, without
flanges, &c. between them & the upper & lower plates are placed layers
of india-rubber, leather, or otherwise, to keep the several parts air-tight, and
the two plates are bolted together by bolts passing through the air chamber,
so that by removing theso bolts the pump can easily be taken to pieces. The
above arrangement of valves can be also used with a pair of single-acting
pumps, so as to give a double effect and continual supply. The pump barrels
in such case may be placed either on the outside or inside of the air chamber.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Louis Adolphe Faure in the Great Seal Patent Office on the
29th April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Louis
ADOLPHE FAURE, Mechanician, of Paris, in the Empire of France, and of
45, Essex Street, Strand, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of October, in the year of our Lord
One thousand eight hundred and fifty-six, in tho twentieth year of Her reign,
did, for Herself, IIer heirs and successors, give and grant unto me, the
said Louis Adolphe Faure, Her special license that I, tho said Louis
Adolphe Faure, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, tho..Channel Islands, and Isle of Man,. an Invention for "AN
IMPROVED FUMP," upon tho. condition (amongst others) that I, the said
Louis Adolphe Faure, 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 months next and
immediately after the date of tho said Letters Patent.
*NOW KNOW YE, that I, the said Louis Adolphe Faure, do hereby declare
the nature of niy 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:-
My pump consists of a cylindrical or square box, having a metallic top-or

page_text: cover, and a similar base or platform; these latter are firmly bolted together
by means of iron tie rods or bolts passing from top to bottom; this forms the
air chamber of the pump. Within this air chamber, and eccentric to it, I
arrange the pump barrel, which consists of a cylindrical tube with or without
flanges, placed vertically, having india-rubber or other packing where its
extremities meet the surfaces of the cover and platform, so as to render its
various parts air-tight. The pump may be either a double-acting or a single-
acting one; if of the former, another similar tube of smaller diameter than the
barrel, passing from the top to the bottom of the air chamber, puts the top.
part of the pump barrel in communication with the water supply; if of single
action, this tube may be omitted. The inlet pipe connecting the pump with
the water supply enters at the bottom of the platform, and within its mouth,
and partly within a chamber formed in the platform, into which the mouth of.
the inlet pipe enters, are placed two valves, which I call the inlet valves. This
last-mentioned chamber, which may be considered as the enlarged mouth of
the inlet pipe, is in immediate communication with the bottom of the barrel,
which when double acting is also in connexion with the top by means of the
before-mentioned tube and a passage formed in the top or cover. . It is
seperated from the air chamber by a plate forming the bottom of the latter,
which plate serves for the seat of two valves opening into the air chamber,
allowing, when in action, the water to pass from the barrel or from the mouth.
of the inlet pipe into, the said air chamber. These valves I call the outlet
valves, being in communication with the opening of the discharge pipe placed
in the side of the air chamber. A partition standing upon the seat of the
inlet valves, and passing along the under surface plate, seperating the inlet
mouth from the air chamber, forms two compartments, each of which contains
one inlet and one outlet valve, seperating them from the other two correspond-
ing valves. The barrel of the pump, which is worked by, an air-tight piston,
and piston rod, is thus in direct communication at its bottom with one com-
partment, containing one set of valves, while at its top, by means of the
passage in the cover and the tube, is in similar connexion with the other
compartment containing the other two valves. The piston rod may be worked
by a balanced lever, or an arm fixed upon a standard, or by any other known
method, and the whole may be mounted on a frame to render it portable.
So as to make the above Specification more clear and intelligible, the
following Drawings and description are appended, which are only intended
to shew the general principles of construction I adopt in forming my pump.
Modifications in the arrangement, dimensions, and details must necessarily
be introduced, according to the particular use and extent to which the same
