page_text: LETTERS PATENT to Jean Baptiste Ambroise Marcelin Jobard, of
Brussels, Belgium, and of 4, South Street, Finsbury, London, Director
of the Museum of Industry at Brussels, for the Invention of "A NEW
SYSTEM OF PUMP."
Sealed the 9th January 1855, and dated the 9th August 1854.
PROVISIONAL SPECIFICATION left by the said Jean Baptiste Ambroise
Marcelin Jobard at the Office of the Commissioners of Patents, with his
Petition, on the 9th August 1854.
I, JEAN BAPTISTE AMBROISE MARCELIN JOBARD, of Brussels, Belgium, and
of 4, South Street, Finsbury, London, Director of the Museum of Industry at
Brussels, do hereby declare the nature of my Invention of "A NEW SYSTEM OF
PUMP to be as follows:-
My Invention consists in employing a tube of vulcanised caoutchouc or any
other similar substance without valve or piston, plunged at one end into the
water or liquid to be raised, and compressed' alternately or in a continuous or
rotative manner at any part of its length, so as to produce a sucking action, as
in the milking of a cow. The liquid is thus raised by suction, and forced from
the opposite extremity of the tube. This system can also be applied to the
injection of air as in bellows.

by the said Jean Baptiste Ambroise Marcelin Jobard in the Great Seal
Patent Office on the 9th February 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
BAPTISTE AMBROISE MARCELIN JOBARD, of Brussels, Belgium, and of 4, South
Street, Finsbury, London, Director of the Museum of Industry at Brussels,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of August, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
nie, the said Jean Baptiste Ambroise Marcelin Jobard, Her special license
that I, the said Jean Baptiste Ambroise Marcelin Jobard, my executors,
administrators, and assigns, or such others as I, the said Jean Baptiste
Ambroise Marcelin Jobard, 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 of "A NEW
SYSTEM OF PUMP," upon the condition, amongst others, that I, the said Jean
Baptiste Ambroise Marcelin Jobard, by an instrument in writing under my
hand and seal, should particularly described 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 I, the said Jean Baptiste Ambroise Marcelin
Jobard, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawing hereto annexed, and to the figures and letters marked thereon, that
is to say :-
My Invention consists in new arrangements of mechanical organs for the
construction of apparatus for drawing and forcing water.
In the annexed Drawing, Figures 1 and 2 represent a sectional elevation and
side view of one of the arrangements. It consists of a cylindrical box A, pro-
vided with two short tubes, to allow the ingress and egress of the extremities
a and b of an indian-rubber pipe. The indian-rubber pipe enters at b, passes
once round the interior of the cylinder A, and comes out at a, enveloping a

page_text: moveable cylinder c, c, which is moved by the excentric d, turning upon its
axis e, which is provided with a crank or handle. By the movement of the
cam the indian-rubber tube receives a successive pressure, which forces forward
the air and water arriving from behind, and thus forms an exhausting and
forcing pump. In lieu of cams conical cylinders, similar to those employed
for crushing chocolate, may be employed.
Figures 3 and 4 represent a modification of the above arrangement. . The
pipe, instead of being rolled round the interior of the cylinder, is rolled round its
exterior, and surrounded with a stiff' moveable hoop a, a, which is successively
pressed over its circumference by the small roller b, b; the pipe enters and
egresses at the side through holes made with a gentle inclination. These two
arrangements of pumps work at option in either direction, which facilitates
the cleaning of the pipes; they may be used for raising water or acids.
Figures 5 and 6 represent a section and plan of an arrangement for elevating
a large quantity of water at a small expense of power. It consists of an
archimedian screw with one or more threads, which presses at the same time a
number of vertical tubes set round the interior of a cylinder. These tubes are
protected by a leather casing c, c, upon which a greasy substance is spread to
facilitate the gliding of the screw upwards. The pipes may be of any required
diameter and length, and may be united on the outside in a single pipe of
larger dimensions.
Figure 7 represents a valve of a new construction. a, a, a, is a metallic
tube open at its two extremities; b, b, a conical tube, pierced all round with
small holes, and soldered at one end to the tube a, a; c, c, is a conical indian-
rubber funnel fitted exactly to the interior of the conical tube b; d is a wooden
peg, which keeps the indian-rubber funnel c in its place, close to the small end
of the tube b. The arrows indicate the direction of the flow of the liquid.
Figure 8 represents a piece of indian-rubber tubing a, provided at each end
with the valve, Figure 7. The valves b, b, are furnished with adjusting rings,
one of which receives a suction pipe c, and the other a propelling pipe d, made
of an elastic material, which serves to regulate the jet c. The pipe forming
the jet has the form of an inverted cone. To set this apparatus in motion
it is necessary to press upon the large pipe a, either with the foot or in any
other suitable manner. By setting various apparatus so constructed round a
reservoir of water, and acting on them by a suitable pressure, a powerful engine
may be obtained.
Figure 9 is a valve similar in principle to that shewn at Figure 7. This
valve is to be set at the extremity of the immersed tube, Figure 10. On taking
hold of the part a, a rotatory jet may be obtained. This apparatus requires

page_text: to be primed by suction before being used. The immersed tube may be rigid,
and the rotatory movement made by means of the hands. This apparatus.
serves for dispersing liquids.
Figure 11 shews a contrivance applicable for cleaning windows; it consists
of a metallic tube, terminating in an indian-rubber bulb a, provided with two
valves, and set in motion by the pressure of the hand. -
I also employ a short strongly articulated straight tube of sufficient strength
and elasticity to overcome the resistance of the atmosphere and raise a column
of water; it may be pressed in the centre by a lever or elliptical cams, and
provided with valves, for the construction of an exhausting and forcing pump.
The power necessary for working the said pumping apparatus may be obtained
from the passage of men, vehicles, or railway carriages over platforms, beneath
which one or several series of-suitable flexible tubes, constructed-as herein-
before described, may be disposed. The movements of a boat, the deflection
of its masts, or the agitation of the waves, may also be applied.for the same
purpose.
1.
I construct a valve in caoutchouc without the use of metal, and consisting
of one or more slits made longitudinally in a tube of caoutchouc, which slits
open like lips upon pressure being applied thereto, and shut after the passage
of fluids by closing one upon the other, like the natural extremities called by
anatomists "meata."
د
I also construct an artificial artery, provided with valvula in thin caoutchouc,
and working by pressure given by the hand, similar to the action of the natural
arteries caused by the pressure of the heart. I place above these artificial
arteries moveable planks or flooring, for the purpose of raising water when
pressed upon by the passage over them of men, animals, or carriages.
. [
I also construct pumps of vulcanized india-rubber having the form of a
water rat or salamander, or any other animal, the tail being represented by a
tube of caoutchouc, one end of which is plunged in the water and the other
inserted into its body, furnished with a valve of the kind above described,
opening in the inside, and of which the mouth is split to form the jet, the
whole forming a pump which can be worked by the pressure of the hand, the
foot, or the knees.
..
My pumps may be applied to the pumping of water from the holds of
vessels. I render them self-acting by suspending in the water at the sides of
the ship one or more planks, each attached horizontally by four chains, like a
common scale board. The pitching and rolling movement of the ship will
suffice to produce an action upon the levers, which press the caoutchouc tubes,
arranged as, pumps, in the manner. before described. My pumps may be

page_text: adapted to the purposes for which air bellows are usually employed by changing
their dimensions.
And having now described the nature of my said Invention, and the manner
of carrying the same into effect, I would have it distinctly understood that I
do not confine myself to the precise details herein laid down, as they may be
varied without departing from the principle upon which my Invention is based;
nor do I claim the application of caoutchouc to the construction of pumps
except in the manner herein-before described; but what I claim is,--
First, the employment of an elastic tube pressed in its centre by a lever, by
elliptical cams, or an archimedian screw, for constructing pumps, as herein-
before described and referred to in Figures 1, 2, 3, 4, 5, and 6 of the Drawing.
Secondly, the peculiar construction of pumps and valves, as herein-before
described and referred to in Figures 7, 8, 9, 10, and 11 of the Drawing.
In witness whereof, I, the said Jean Baptiste Ambroise Marcelin Jobard,
have hereunto set my hand and seal, this Twenty-seventh day of
January, in the year of our Lord One thousand eight hundred and
fifty-five.
