CERTAIN IMPROVEMENTS IN ENGINES OR MACHINES FOR CONVEYING WATER OR OTHER FLUIDS
Year: 1834

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN.
BEARE, of Pall Mall East, in the County of Middlesex, Civil Engineer, send
greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Royal Letters Patent, under the Great Seal of Great Britain, bearing
date at Westminster, the Twelfth day of April, in the fourth year of His
reign, did, for Himself, His heirs and successors, give and grant unto me, the
said John Bearc, His especial licence, full power, sole privilege and authority,
that I, the said John Beare, my executors, administrators, and assigns, or
such others as I, the said John Beare, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein mentioned, should and lawfully
might make, use, exercise, and vend, within England and Wales and the
Town of Berwick-upon-Tweed, an Invention of "CERTAIN IMPROVEMENTS IN
ENGINES OR MACHINES FOR CONVEYING WATER OR OTHER FLUIDS;" in which said
Letters Patent is contained a proviso obliging me, the said John Bearc, to
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in His Majesty's High
Court of Chancery within six calendar months next and immediately after the
date of the said in part recited Letters Patent, as in and by the same, refe-
rence being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Beare, do hereby declare that the nature of my said Invention, and in

page_text: what manner the same is to performed, are particularly described and ascer-
tained in and by the following description thereof, reference being thereto had,
and to the Drawings hereunto annexed (that is to say)
These Improvements in Engines or Machines for Raising or Conveying
Water or other Fluids consists:-Firstly, in an improvement in the form or
construction of the chambers of a vacuum pump, which is designed for the
purpose of affording greater facility of access to the bucket and other internal
parts than can be obtained by the ordinary constructions of pumps.
Secondly, a variation or modification in the construction, by which the same
advantages may be obtained in reference to a lift or force pump.
Thirdly, a contrivance, which I call an air retainer, for the purpose of
assisting the upward flow of the liquor through the suction pipe.
Fourthly, the adaptation of a mechanical apparatus by which I am enabled
to combine the operations of a vaccuum pump and a force pump with the
ordinary action of the lever of a water closet.
And, fifthly, in the employment of a flexible diaphram connected to the
piston of a beer engine.
In the accompanying Drawings, Fig. 1 represents the external appearance
of a ship's pump constructed with the first-mentioned improvements. Fig. 2
is a section of the same, taken vertically through the middle of the pump, and
shewing the whole of the interior and the working parts. The upper and
lower chambers a, a, and b, b, are of cast iron or other suitable material,
formed in one piece without flange joints. The cap, cover, or top piece e is
movable, being loose, and fitted to the rim of the upper chamber by a lip;
it is thereby capable of being instantly removed in order to obtain access to
the interior. In this pump I employ a flexible conical diaphram d, of leather
or other suitable material, the one part of which is secured to the bucket and
the bell-formed shield e, employed to prevent the diaphram from collapsing as
the bucket ascends; the other part of the conical diaphram is by a couple of
brass or copper rings f. f, screwed together, nipped tightly, as shewn detached
from the pump barrel at Fig. 3. The bucket is then let down into the barrel,
as seen at Fig. 2, the rings resting upon the inner ledge g. 9, of the chambers;
and they may, if required, be slightly fixed within the barrel by a wedge driven
between the barrel and the edge of the rings, or by any other convenient
mode.
Fig. 4 is a lifting or forcing pump for mines or deep wells. This Figure
represents the external appearance of a pump as fixed within a well. Fig. 5
is a vertical section of the same, taken through the middle of the pump, and
showing the parts within. In this instance the chambers, with the cap also,

upper or square chamber at a, a, a, a, which is closed by a plate b, bolted
with packing, as seen at Fig. 4.

Fig. 6, the contrivance which I call an air retainer, represents the
part of the suction pipe, attached, as usual, by flanges to the bottom of the
lower chamber of the pump barrel. Fig. 7 is a section of the same, taken
through the middle. This portion of the suction pipe is considerably enlarged
in its diameter, for the purpose of affording space within for the reception of a
volume of air, the elastic force of which is intended to aid the ascent of the
water. Within this enlarged or protuberant part of the suction pipe a, a, a
tube 6 is inserted, which is held by an upper rim or flange between the bottom
flange of the chamber and the top flange of the suction pipe. This tube
enables a volume of air to occupy the interior of the suction pipe, and pre-
vents that volume of air from being drawn up into the pump barrel, and
which thus confined by the tube 6 in the space c, c, within the suction pipe,
acts continually as an elastic pressure, aiding the upward flow of the water
or other liquor.

Fig. 8 exhibits, in elevation, the external appearance of the principle parts
of a water closet which is designed to act without the necessity of placing a
cistern of water above. In this Figure, a is the basin; b, the discharging
valve box; c, the discharging pipe; d, d, the lever by means of which the
discharge valve is opened by a handle and rod e; a barrel or chamber f con-
tains the plunger of a lifting or forcing pump; and to the bottom of this
pump the suction pipe g is attached, leading from a reservoir
the pipe or tube by which water is forced up by the pump into
the lever d the pump rod k is connected by a joint, so that in raising the
handle e for the purpose of opening the discharge valve, the lever d also lifts
the rod k, and causes the plunger to force a volume of water up into the
basin; and in depressing the handle k again the discharging valve is closed,
and the plunger forced down, ready to lift another column of water at the
next stroke.

engine; Fig. 10 is a section of the same; and Fig. 11 shews the flexible
conical diaphram detached. In this instance the outer edge of the diaphram
may be confined between the flanges of the upper and lower portions of the
barrel, or it may be confined by rings and placed upon a ledge within the barrel,
as described in reference to Fig. 2. The inner part of the diaphram is to
be attached to the bucket, also as Fig. 2, and the foot valve is formed by a
perforated cock, with a clack on the upper side. When adapted to a beer
