Year: 1862

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IMPROVEMENTS
IN PUMPS." A communication from abroad by Jean Marie Henri Paul
Sealed the 10th October 1862, and dated the 14th April 1862.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
14th April 1862.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PUMPS," (communicated to me from abroad by Jean Marie
Henri Paul Metivier, of 34, Rue Keller, Paris, France), to be as follows:-
The characteristic feature of this Invention of improvements in pumps is
the employment of two shafts together with inclined pump barrels and pistons,
as hereafter explained. One of the shafts is inclined at any desired angle, and
the two shafts are coupled together by a universal or other joint, ensuring the
same speed to both and causing them to revolve in the same direction. One
of the shafts carries, through a horizontal disc or cross bars, a pair or more of
pump barrels set at the same angle as the inclined shaft, while the other (say,
the inclined shaft) has fixed on the lower part an inclined cross head with rods
and pistons, also inclined to correspond and work in the pump barrels. A

page_text: vessel or case fitted with a cover, which may be removed when required, has
a suction pipe fitted at the lower and discharge pipe at the upper part; both
pipes are provided with suitable valves, and in this vessel the barrels and
pistons are enclosed. The pump barrels (say, four) are suspended from the
under side of the horizontal disc or cross bars in such manner as to be able to
adapt themselves to the inclinations of the pistons. A ring of some strong
flexible material unites and keeps the pumps water and air tight, so that the
top of the pump barrel is in communication with the discharge, while the
bottom of the pumps is in communication with the lower part of the vessel.
A diaphragm may, if desired, surround the lower part of the plate. On motion
being communicated to the upper shaft similar motion is transmitted to the
lower and to the pump barrels and piston respectively; that is to say, if at the
commencement of the rotation the piston was at the bottom of one barrel and
the opposite piston at the top of the opposite barrel, then, upon the completion
of a semi-rotation, that which was at the top would have become at the bottom
of the barrel, and vice versa. As the barrels move, or as the pistons move in
the barrels, so air, water, or other liquid is drawn into and discharged from
the vessel: The action is similar, whether the shafts receive a continuous
rotary motion in one direction or an alternate rotary motion. Either the
barrels may be made to move over the pistons or the pistons may be made
to move in the barrels, according to which shaft they are respectively con-
nected to.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 14th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of April, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Richard Archibald Brooman, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such others
as I, the said Richard Archibald Brooman, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and

page_text: 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 PUMPS," (communicated to me from abroad by Jean
Marie Henri Paul Metivier, of 34, Rue Keller, Paris, France), upon the
condition (amongst others) that I, the said Richard Archibald Brooman, my
executors or administrators, by an instrument in writing under my, 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 Richard Archibald Brooman, 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 thereof, reference being had to the Drawings hereunto
annexed, that is to say:
is
The characteristic feature of this Invention of improvements in pumps
the employment of two shafts together with inclined pump barrels and pistons,
as hereafter explained. One of the shafts is inclined at any desired angle, and
the two shafts are coupled together by a universal or other joint ensuring the
same speed to both and causing them to revolve in the same direction. One
of the shafts carries, through a horizontal disc or cross bars, a pair or more of
pump barrels set at the same angle as the inclined shaft, while the other (say,
the inclined shaft) bas fixed on the lower part an inclined cross head with rods
and pistons, also inclined to correspond with and work in the pump barrels.
A vessel or case fitted with a cover, which may be removed when required,
has a suction pipe fitted at the lower and a discharge pipe at the upper part;
both pipes are provided with suitable valves, and in this vessel the barrels and
pistons are enclosed. The pump barrels (say, four) are suspended from the
under side of the horizontal disc or cross bars in such manner as to be able to
adapt themselves to the inclinations of the pistons. A ring of some strong
flexible material unites and keeps the pumps water and air tight, so that the
top of the pump barrels is in communication with the discharge, while the
bottom of the pumps is in communication with the lower part of the vessel.
A diaphragm may, if desired, surround the lower part of the plate.
Figure 1 of the accompanying. Drawings is a vertical section, and Figure 2
is a horizontal section, of a pump fitted with four barrels, according to this
Invention.

page_text: A is a metal or wood case enclosing the pumps; B is a cover secured to
the case by bolts or screws, and in such manner that it may with facility be
removed when required; C is the suction pipe, and D is the discharge pipe,
each being provided with a stop. valve; K is a packing of leather or other
flexible material between the cover B and case A. The two shafts M, N,
are united at the point O and have a continuous or alternate rotary motion
imparted to them by means of a crank pulley, toothed wheels, or other appli-
ance for communicating motive power. H is a plate united by bolts to a
bottom plate H' keyed to the shaft M, the plate H is made tight by packing a
inserted in a groove b formed in a flange depending from the cover. To the
lower plate H¹ four pump barrels F are attached, each barrel being free to
move about the points I through universal joints, so that they may assume
any inclination, according to the motion of the pistons. A suitable packing
unites the barrels of the pumps to the plate H' so that no water may pass up
round the outside of the barrels; the upper end of the barrels is enlarged, and
over this enlargement leather washers d are placed and secured to the plate H',
the washers have sufficient play to allow of their moving with the barrels.
L, L, are diaphragms between the plates H and H' to maintain around the
pump barrels a volume of water and to prevent unnecessary agitation that
would otherwise take place in the case; sometimes, however, these diaphragms
are dispensed with. The plates H, H', are held together by bolts g, 9; f is a
packing of india-rubber inserted between the flanges. P is a cross bar fixed
to the second or inclined shaft N, and to which the pistons Q are fixed. These
pistons are fitted with semicircular, valves h or with ordinary valves; the
piston rods are parallel with the shaft N and are set at an equal distance from
its axis. On motion being communicated to the shaft M similar motion is
transmitted to the lower shaft N, to the plates H, H, barrels F, and pistons Q.
If at the commencement of rotation one piston was at the bottom of one
barrel and the opposite piston at the top of the opposite barrel, then, upon the
completion of a semi-rotation, that which was at the top would have become
at the bottom of the barrel, and vice versa. As the barrels move, or as the
pistons move in the barrels, so air, water, or other liquid is drawn into and
discharged from the pump. The action is similar whether the shafts receive
a continuous rotary motion in one direction or an alternate rotary motion.
Loss of power by friction is avoided and the weight is concentrated on one
point z, in which the end of the shaft N rests; k is a screw for regulating the
height of the shafts M and N. The cover B carries a dome-shaped vessel m
fitted with a stuffing box, through which the shaft M passes; n is a stirrup
above the dome m for supporting the shafts of the wheels 9, 9', and that of the

page_text: crank, which may be placed on a vertical shaft or on a prolongation of one of
the shafts on which the wheels q¹ are mounted; r, r, are sight holes in the
case and plates for facilitating the placing in position of the different parts and
for viewing the interior. Either the barrels may be made to move over the
pistons or the pistons may be made to move in the barrels, according to which
shaft they are respectively connected to.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim the employment
in pumps of two shafts jointed together, and of inclined pump barrels and
pistons, all being fitted and caused to act, substantially as herein-before
described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Fourteenth day of October, One
thousand eight hundred and sixty-two.
K. A. BROUMAN. (L.S.)
