PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition, on
the 26th July 1864.
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices,
24, Rue du Mont Thabor, Paris, in the Empire of France, and 38, Por-
chester Terrace, Bayswater, in the County of Middlesex, Patent Agent, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
FEED APPARATUS FOR STEAM AND OTHER BOILERS, WHICH IMPROVEMENTS ARE ALSO
APPLICABLE TO RAISING AND FORCING FLUIDS," communicated to me by Gilles
Deprez, a person resident at Seraing, in the Kingdom of Belgium, to be as
follows:-
This Invention consists in certain improvements in feed apparatus for high-
pressure and other steam boilers, which improvements are also applicable to

page_text: raising and forcing fluids, and by means of which great economy of fuel is
secured, and risk of derangement entirely obviated.
The annexed Drawing represents a section of the apparatus, in which a is a
pump chamber; b, c, and d, three lateral openings covered by a brass box e;
f, a conduit with tap f¹ branching off into two tubes g, h, with taps g', h¹; i,
a hollow valve; j, its rod; and k, the main piston working in the pump
chamber; and l, its rod. The two rods j and I are set in movement by the
machine, and cold water drawn from the well by a supply tube opening at c,
filling the pump chamber a. At the return stroke of the piston k the water
is driven from the chamber into the box e, and from thence into the conduits f,
by one or other of the openings 6 or d, alternately uncovered by the valve i.
At the opposite end of the tube h is placed a reservoir fixed on one of the flues
of the boiler in which the water is driven on leaving the tube f when the tap
g', placed on the tube 9 (communicating with the boiler it is intended to
feed) is shut, and in which it is heated to any temperature above that of
boiling water. The water being suitably heated, the communication between
the pump, the well, and the boiler is intercepted, and the heated water is
drawn back into the pump, and then driven into the boiler by shutting off
the communication with the last reservoir and opening that with the boiler.

page_text: Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN APPARATUS FOR STEAM AND OTHER BOILERS, WHICH IMPROVE-
MENTS ARE ALSO APPLICABLE TO RAISING AND FORCING FLUIDS," communicated to
me by Gilles Deprez, a person resident at Seraing, in the Kingdom of
Belgium, upon the condition (amongst others) that I, the said Henri Adrien
Bonneville, my executors or administrators, by an instrument in writing
under my, or their, or one of their bands and seals, 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 the said Letters Patent.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, 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 :-
This Invention consists in certain improvements in feed apparatus for high-
pressure and other steam boilers, which improvements are also applicable to
raising and forcing fluids, and by means of which great economy of fuel is
secured, and risk of derangement entirely obviated.
The annexed Drawings represent, Fig. 1, a plan view of the improved appa-
ratus; Fig. 2, a section of the same by the line A, B, of the plan; Fig. 3, a
transversal section by the line C, D; and Fig. 4, a front view by the line E, F.
In these Figures a is the pump chamber; b, the piston; c and d, com-
pression or outlet ways; e, entrance conduit; f, slide valve; g, brass box or
chamber; h, opening in said box; i, tap; x and y, branches of tube j, z tap;.
u, aspiration tube, communicating with well or cold water tank.
The improved apparatus is composed of a pump chamber a, which may be
placed either vertically or horizontally. This pump chamber has exactly the
form of a steam cylinder. Inside it works a solid piston 6 with metal packing.
It is made with two distributing conduits c and d, which are exclusively used
for the compression or outlet of the water. A third conduit e, between the
preceding ones, also forms part of the cylinder. By this conduit the water
enters. The three conduits open into a table or plate well adjusted and cast.
with the cylinder, in which are formed three rectangular openings or ports.
A brass box g covers exactly the tube and the three openings; it is bored
from above with a circular opening h, closed by a cock i. A slide valve ƒ of
brass is placed on the port table, which it covers. This slide valve is made to.
slide backwards and forwards so that in its rectilinear stroke it comes alter-
nately in communication with the central port e, and one or other of the side

page_text: ports c, d. Instead of a slide valve two small pistons serving the same pur-
pose may be used. The conduit e, cast with the cylinder, receives an aspirating
tube which descends into the well or water tank, and this tube has the form
of a syphon, so that the cold water rising in it to a certain height, the distance
to which the water is to be raised is diminished, and it thus becomes easy to
set the pump to work.
In direct-action apparatus like that represented in the Drawing, the pump
rod may be lengthened and made to pass through a small air cylinder provided
with two extreme taps. On this prolongation a small piston may be placed,
so that as the taps are more or less open, this air cylinder will play the part
of a regulator of the movement, and will give it all the softness desirable.
Let us suppose that the piston moves from right to left in the pump
chamber, the slide valve then has the position shown in the Drawing, that is
to say, the water enters by the conduit e, and passes from thence into the slide
valve f, the conduit c, and the pump chamber, thus following the stroke of the
piston. When the piston is arrived at the extremity of its stroke the pump
body is full of water, the return stroke then begins, but the slide valve f no
longer covers the orifice of the conduit c; the latter being in direct commu-
nication with the interior of the box g, the water is driven into the latter, and
rises in the tube j.
The distributing valve being subjected from without to the pressure of the
atmosphere or perhaps even a stronger pressure, and a vacuum being formed
beneath it, it is supposed to remain perfectly well attached to the table without
any tendency to rise.
.
The tubej branches off into two parts x and y, on each of which is placed
a tapi, z. One of these branches opens into a reservoir well closed and placed
on the brickwork of the boiler. This tank may be of any convenient form,
according to circumstances. It should be placed in one of the flues of the
furnace, so that the flames and hot gases disengaged may heat the water
driven into it by the pump, and carry the water to any temperature above
boiling water; it is provided with a safety valve and an atmospheric valve.
When this water is well heated it is used for feeding the boiler, which is done
by closing the tap of the aspirating tube, which plunges in the well or reservoir,
and closing the cock i while opening that z, when the pump draws the water
which had been driven into the heating tank, and is now in a boiling state, or
rather this water with its steam descend of themselves into the pump chamber,
the reservoir being in a rather elevated position, and then the slide valve f
distributes hot water instead of cold water. For this purpose a second tube
is placed on the heating tank and connected with the opening u, commu-

page_text: nicating with the port e and the under part of the slide valve f. The hot
water enters immediately under the valve, penetrates into the pump chamber,
is driven into the box g, and rises into the tube j, but cannot return to the
tank because the tap i is closed, while the tap z, which opens the commu-
nication with the boiler, is open. Thus this boiling water is driven imme-
diately into the boiler, which operation is the object of the apparatus. This
apparatus is not at all liable to derangement, because the distribution is
made by a valve worked by the engine itself, which is not the case with valves
the working of which is subject to the pressure which reigns in the pump
chamber. It is well known that the moment the water begins to vaporize
the valves can no longer rise. The slide valve and piston may be worked by
excentrics, cams, cranks, or rods of any kind, as the case may require.
Thus the improved apparatus allows of realising a great economy in fuel.
It is of great simplicity, and not liable to get out of order, whereas in feeding
with luke-warm water even valves occasion continual embarassments. The
waste steam of the engine may be utilised when the water is not heated
above 100° centigrade (212° Fahrenheit), by conducting this steam directly
into the heating tank, by means of a plunging tube, where it would become
partially condensed while heating the water.
The pumping part of this improved apparatus may be applied to air pumps,
exhaust pumps, fire engines, and divers other means of raising and forcing
fluids.
Having thus described the nature of the said Invention communicated to
me by my foreign correspondent, I claim and wish to secure by Letters
Patent the improvements in feed apparatus for steam and other boilers above
described and represented in the accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have here-
unto set my hand and seal, this Sixteenth day of January, in the
year of our Lord One thousand eight hundred and sixty-five.
