Year: 1865

page_text: LETTERS PATENT to Hyde Bateman, of Barnes, in the County of Surrey,
Surveyor, and Edward Gooch Garrard, of Vauxhall, in the same County,
Wine Merchant, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF PUMPS FOR RAISING OR FORCING WATER OR OTHER LIQUIDS
OR FLUIDS."
Sealed the 17th April 1866, and dated the 24th October 1865.
PROVISIONAL SPECIFICATION left by the said Hyde Bateman and
Edward Gooch Garrard at the Office of the Commissioners of Patents,
with their Petition, on the 24th October 1865.
We, HYDE BATEMAN, of Barnes, in the County of Surrey, Surveyor, and
EDWARD GOOCH GARRARD, of Vauxhall, in the same County, Wine Merchant,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF PUMPS FOR RAISING OR FORCING WATER OR OTHER LIQUIDS OR
FLUIDS," to be as follows:-
Our Invention of "Improvements in the Construction of Pumps for Raising
or Forcing Water, or other Liquids or Fluids" consists of a shallow cylindrical
shaped water chamber or vessel divided circumferentially into two parts, one
of which is fixed, and the other moveable by means of a lever which projects
therefrom through the outer casing of the pump. The moveable part of the
water chamber has a central cylindrical valve chamber attached thereto, and
moving with it. The edges of the cylindrical water chamber are packed so
as to keep the chamber water-tight, and yet admit of the moveable part

page_text: working on the stationary part. The fixed and moveable parts of the water
chamber are provided with pistons, which fit the annular space in the
cylinder between the periphery of the valve chamber and the inner diameter
of the cylinder. The valve chamber is provided with inlet and outlet valves
which communicate with suitable pipes, from one of which the water or other
liquid or fluid is supplied to the interior of the pump, while the liquid or fluid
escapes from the pump through the other pipe. It will now be understood
that the internal capacity of the water chamber is divided by its fixed and
moveable pistons into four compartments, the capacities of each of which are
increased or diminished as the moveable pistons of the water chamber are
made to advance towards or recede from the fixed pistons by the action of the
lever or pump handle outside. It will now be understood that by giving
motion to the moveable pistons by means of the handle any water or other
liquid or fluid that is found between the fixed and advancing pistons will be
forced out through the valves into the exit pipe, and at the same time the
advancing pistons will create a vacuum behind them into which the liquid or
fluid from the supply pipe will rush, and will in its turn be forced out of the
exit valves when the moveable pistons make the return stroke. By the com-
bination of the four compartments with their proper valves a continuous flow
of liquid or other fluid from the pump may be maintained by the reciprocating
motion of the handle or lever. If desired two handles or levers, one pro-
jecting from each side of the pump, may be employed, and thus form a cheap
and very effective fire-engine. The pump is applicable either as an ordinary
lifting or forcing pump, or for exhausting, forcing, or compressing air or
gases.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Hyde Bateman and Edward Gooch Garrard in the Great
Seal Patent Office on the 24th April 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HYDE
BATEMAN, of Barnes, in the County of Surrey, Surveyor, and EDWARD GOOCH
GARRARD, of Vauxhall, in the same County, Wine Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of October, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Hyde Bateman and Edward Gooch Garrard, Her special licence that

page_text: we, the said Hyde Bateman and Edward Gooch Garrard, our executors,
administrators, and assigns, or such others as we, the said Hyde Bateman
and Edward Gooch Garrard, our 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 for
"IMPROVEMENTS IN THE CONSTRUCTION OF PUMPS FOR RAISING OR FORCING WATER
OR OTHER LIQUIDS OR FLUIDS," upon the condition (amongst others) that we,
the said Hyde Bateman and Edward Gooch Garrard, our executors or admi-
nistrators, by an instrument in writing under our, or their, or one of their
hands 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 Hyde Bateman, on behalf of myself and
of the said Edward Gooch Garrard, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement, reference
being had to the Drawing hereunto annexed, and to the letters and figures
marked thereon (that is to say):
Our Invention of "Improvements in the Construction of Pumps for Raising
or Forcing Water or other Liquids or Fluids," consists of a shallow cylindrical
shaped water chamber or vessel divided circumferentially into two parts, one
of which is fixed, and the other moveable by means of a lever which projects
therefrom through the outer casing of the pump.
In the accompanying Drawing Fig. 1 is an external side elevation of a
pump constructed according to our improvements, shewing the outer casing
with the inlet or outlet valve at the central part; Fig. 2 is an end elevation
of the same, shewing the inlet valve at one side and the outlet valve at the
opposite side, and shewing also the slot or guide in which work the arm or
lever whereby the moveable part of the internal cylinder is worked; Fig. 3
is an inside view of the pump; with one half of the outer casing and also one
half of the working cylinder removed in order to shew the arrangement of the
interior; Fig. 4 is a longitudinal vertical section shewing the same half of
the pump, but certain of the parts, such as the central valve chamber and the
pistons, shewn in section; Fig. 5 is a transverse vertical section taken in the
line y, y, of Fig. 3, shewing the inlet and outlet passages and valves, also
the packing of the inner cylinder and the slots or guides for the arm or lever

page_text: whereby the moveable part of the inner cylinder is actuated; Fig. 6 is an
external elevation of this moveable half of the cylinder with the arms and
levers attached thereto; Fig. 7 is an internal elevation of the same, shewing
the packing grooves against which the other half of the cylinder works, and
shewing also the central valve chamber and pistons connected with: this half
of the cylinder; Fig. 8 is a transverse vertical section taken through the
external casing, and shewing within the pump and working parts connected
therewith.
The pump is composed mainly of two parts a and b, which are enclosed within
an outer casing A simply for protection and appearance, and not because such
casing is an essential part of the machine. The part à of the working
cylinder or water chamber is moveable, and the part 6 is fixed. Either the
moveable part a or the fixed part 6 of the water chamber has a central
cylindrical valve chamber e attached thereto, and this valve chamber if con-
nected with the moveable part will move with it. The edges or rubbing
surfaces of the cylindrical water chamber are packed at c so as to keep the
chamber water-tight, and yet admit of the moveablo part a working on the
stationary part b. The fixed and moveable parts a and b of the water
chamber are provided with pistons d, d*, which fit the annular space in the
cylinder between the periphery of the valve chamber e and the inner diameter
of the cylinder or casing f. The valve chamber e is provided with inlet and
outlet valves g and h, which are kept in their proper position by hollow
spindles 1, 1, Figures 3, 4, and 5. These valves 9 and h communicate with
suitable pipes i, from one of which the water or other liquid or fluid is
supplied to the interior of the pump, while the liquid or fluid escapes from
the pump through the other pipe j. It will now be understood that the
internal capacity of the water chamber is divided by its fixed pistons d, d, and
moveable pistons d*, d*, into four compartments, the capacities of each of
which are increased or diminished as the moveable pistons d*, d*, of the water
chamber are made to advance towards or recede from the fixed pistons d, d,
by the action of the levers or pump handles d², d, outside. It will now be
understood that by giving motion to the moveable pistons d*, d*, by means of
the bandle d', which is fixed to the moveable balf a of the cylinder, any water
or other liquid or fluid that is found between the fixed and advancing pistons d
and d will be forced out through the valve h into the exit pipe j, and at the
same time the advancing pistons d* will create a vacuum behind them into
which the liquid or fluid from the supply pipe i will rush, and will in its turn
be forced out of the exit valves h when the moveable pistons d✶ make the
return stroke. By the combination of the four compartments with their proper

page_text: valves a continuous flow of liquid or other fluid from the pump may be
maintained by the reciprocating motion of the handle or lever d³. If desired,
two handles or levers d', one projecting from each side of the pump as shewn
in the Drawing, may be employed, and thus form a cheap and very effective
fire-engine. The pump is applicable either as an ordinary lifting or forcing
pump, or for exhausting, forcing, or compressing air or gases. The two
halves a and 6 of the working cylinder or water chamber are kept water-tight
by means of the tightening screws k, k, which may be screwed up from the
outside.
Having now described our Invention of "Improvements in the Construc-
tion of Pumps for Raising or Forcing Water or other Liquids or Fluids," and
having explained the manner of carrying the same into effect, we claim as the
Invention secured to us by Letters Patent as aforesaid, the combination of the
fixed and moveable parts a and b forming the working cylinder or water
chamber, which is provided with a central valve chamber and fixed and
moveable pistons, as herein set forth.
In witness whereof, I, the said Hyde Bateman, have hereunto set my
hand and seal, the Twenty-third day of April, in the year of our
Lord One thousand eight hundred and sixty-six.
Witness,
J. W. MOFFATT,
