Sealed the 5th February 1867, and dated the 10th November 1866.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 10th November.1866, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices,' 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED APPARATUS
FOR PUMPING OR VENTILATING," a communication from Paschal Joseph Hognoul,
& person resident at Liège, in the Kingdom of Belgium, Engineer, and have
petitioned Her Majesty to grant unto me, my executors, administrators,

page_text: and assigns, Her Royal Letters Patent for the same, and made solemn
Declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification under my hand and seal
fully describes and ascertains the nature of the Invention, and the manner in
which the same is to be performed, reference being had to the accompanying
Drawings, and to the figures and letters marked thereon, that is to say:—
The Invention communicated to me relates to an improved pump which
may be used either to draw water or for the purpose of ventilation; it is
specially applicable to mining operations or hydraulic works. It is both a
suction and a forcing pump, and consists in an elliptical box made of cast
iron or some other convenient and resisting metal, in which turn two parallel
fluted rollers or cores bearing big rounded teeth and slopes, which catch into
each other as they roll round. During their rotation, which is actuated by
their axles passing through the bottoms of the box, these teeth graze the
inside of the box and catch into each other at the central part of the box,
leaving no space between them and the inside part of the box they graze,
sucking up the water or the air by a conduit opening into one of the sides of
the box, whilst forcing the water or air by another conduit on the opposite
side of the same.
For the better understanding of the distribution of this improved pump or
ventilator reference has been had to the accompanying Drawings, Figure 1 of
which is an inside view in elevation, and Figure 2 a section in elevation of the
same.
In Figure 1, A, A, are stuffing boxes which serve to maintain the inside
pressure; B, B, are the big rounded teeth of the gearing serving to suck up
the air or water; C is the pump barrel; D, D, are the extremities of the
sucking and forcing tubes.; E is the frame.
In Figure. 2, F, F, are the bottoms of the pump barrel; G, G, are stuffing
boxes;. H, H, are the driving shafts, on which are fixed the cores or drums
bearing the big rounded teeth or gearing B, B; I, I, are the sucking and forcing
tubes of the water or air; J. is the driving block actuating the driving shaft H;
support of the driving shaft H; L is the frame; M, the foundation
brickwork; N, the central part of the pump.
K is
the
This pump is used as above described to draw air or water. Its dimensions
may vary according to its application. The greater or less force it may have lies
in the greater or less vacuum existing between the big rounded teeth or
gearing. Those intended for the purposes of ventilation. require a motive power
less great.

page_text: Having now described the nature of the said Invention, and the manner of
carrying the same into effect, I would have it understood that I do not confine
myself to the precise details above enumerated, as these may obviously be
modified without departing from the principle of the Invention according to
the special construction and intended applications of the same; but what I
claim is, an apparatus which may be indifferently used for drawing water or
for the purposes of ventilation, substantially as herein-before set forth and
described, and represented in the different Figures of the accompanying
Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereto
set my hand and seal, this Third day of November, in the year of our
Lord One thousand eight hundred and sixty-six.
