HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS
IN APPARATUS FOR REGULATING AND MEASURING THE FLOW OF FLUIDS."
A communication from abroad by Francisco de Paula Isaura y Fargas, Pedro
Garcia y Corvera, and José Barrufet y Veciana, all of Barcelona, in the Kingdom of
Spain..
This apparatus consists of three principal parts, namely; a cylindrical barrel
enclosing a piston, and termed a regulator, a cylindrical conducting pipe communi-
cating with one end of the regulator and placed at a right angle to the same, and
an inlet chamber provided with a disc valve and fluid passages, said inlet chamber
being placed at the opposite side of the conducting pipe and opening into the latter.
The water or other fluid enters the apparatus through a pipo which communicates
by two branches with two orifices, where it strikes against the face of the said disc
valve so as to remove the latter from its seat until a projection on its back is
arrested by tho cover of the inlet chamber. The fluid then flows into the inlet
chamber and through a perforation of the disc valve into a channel which opens
into the said conducting pipe. From the latter the fluid passes into the base of
the regulator and between the circumference of the piston and the inner surface of
the barrel to the upper part of the regulator, the piston leaving sufficient play
between itself and the barrel. If the quantity of fluid, entering the base of the
regulator is greater than what can pass between the floating piston and the walls of
CD 1.77

page_text: the barrel, the piston will be lifted, and thereby act upon one arm of a lever situated
inside the conducting pipe, and the other arm of which enters a recesss of the disc
valve. The motion of the lever causes the disc to descend or to turn on its face,
whereby the perforation of the disc is moved away from the aperture which
communicates with the conducting pipe, and thus the supply of water shut off or
diminished.
The floating piston is made hollow and guided in the axis of the barrel by a
piston rod extending upward and downward through an upper end and a lower
guide.
The fluid which has passed into the upper part of the barrel escapes through an
opening in the upper cover. By introducing into the hollow piston a smaller or
greater quantity of weights, the quantity of water passing between the piston and
the barrel may be regulated, that is to say, the piston may be lifted earlier or later.
The fluid escapes from the apparatus through a pipe situated at the top of the
regulator; and as the channel which connects the inlet chamber with the conducting
pipe is wider than the perforation in the disc valve, there will be a pressure of
water against the valve face.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Herbert John Haddan in the Great Seal Patent Office on the 10th
May 1881.

IN APPARATUS FOR REGULATING AND MEASURING THE FLOW OF FLUIDS."
A communication from abroad by Francisco de Paula Isaura y Fargas, Pedro
Garcia y Corvera, and José Barrufet y Veciana, all of Barcelona, in the Kingdom of
Spain.
This apparatus consists of three principal parts, namely, a cylindrical barrel
enclosing a piston, and termed a regulator, a cylindrical conducting pipe communi-
cating with one end of the regulator and placed at a right angle to the same, and
an inlet chamber provided with a disc valve and fluid passages, said inlet chamber
being placed at the opposite side of the conducting pipe and opening into the
latter. The water or other fluid enters the apparatus through a pipe which
communicates by two branches with two orifices, where it strikes against the face
of the said di-c valve so as to remove the latter form its seat until a projection on
its back is arrested by the cover of the inlet chamber. The fluid then flows into
the inlet chamber and through a perforation of the disc valve into a channel which
opens into the said constructing pipe. From the latter the fluid passes into the
base of the regulator and between the circumference of the piston and the inner
surface of the barrel to the upper part of the regulator, the piston leaving sufficient

page_text: play between itself and the barrel. If the quantity of fluid entering the base of
the regulator is greater than what can pass between the floating piston and the
walls of the barrel, the piston will be lifted, and thereby act upon one arm of a
lever situated inside the conducting pipe, and the other arm of which enters a
recess of the disc valve. The motion of the lever causes the disc to descend or to
turn on its face, whereby the perforation of the disc is moved away from the
aperture which communicates with the conducting pipe, and thus the supply of
water shut off or diminished. The floating piston is made hollow and guided in
the axis of the barrel by a piston rod extending upward and downward through an
upper and a lower guide.
The fluid which has passed into the upper part of the barrel escapes through an
opening in the upper cover. By introducing into the hollow piston a smaller or
greater quantity of weights, the quantity of water passing between the piston
and the barrel inay be regulated, that is to say, the piston may be lifted earlier
or later.
The fluid escapes from the apparatus through a pipe situated on the top of the
regulator; and as the channel which connects the inlet chamber with the conducting
pipe is wider than the perforation in the disc valve, there will be a pressure of
water against the valve face.
The lettering upon the three accompanying Figures in the Drawing is the same
in all, referring to the same corresponding parts in each.
The first Figure is a vertical lateral section showing a pump barrel B, called here
the regulator, and forming one connected piece with the horizontal tube D, to
which the name of the conductor has been given. To this conductor is fitted, by
means of a screw arrangement at OH, a special mechanism denominated the
compressor. This last is, in its turn again, hermetically shut by means of the
stopper TU, and these portions, taken as a whole, and looked at from without,
present the appearance of two cylinders joined at right angles.
The second Figure is a vertical section, though presenting a front view, of the
compressor mechanism, which is again shown by means of a section M N in the
upper part of the said Figure 2.
Hence it will be seen that this apparatus consists of three principal parts in two
pieces only, namely, the part called the compressor, screwed on to the conductor D
at OH and the regulator B connected therewith.
The mechanical arrangement of the part called the compressor consists of the
following A partition represented by RS, HO, which at its lower part gives
access to the tube G, and thus admits the water into the apparatus; at the bottom
of this tube, where it is joined to the partition, are fitted two orifices or pipes at right
angles made in the thickness of the partition, and communicating at RS with the
inner receptacle of the compressor, as represented by b, b. On the face RS of the
partition, and in the space intervening between the said two orifices b, b', there is
left a slit b, which is the opening of communication between the interior A of
the compressor and the interior of D of the conductor. Through this slit passes
the end n of the lever, the end of which supports at the same time the disc c, which
ascends or descends, following the said end of the lever as it goes up or down.
However, if a knob or protuberance x be fitted to said partition RS, HO, on
its RS face at a point at the side nearest the perimeter of the circle, the disc C will
work excentric fashion, turning round instead of moving up and down vertically,
so that the desired effect is the same, as will appear in the sequel.
The said partition RS, HO, carries on its OH face a projecting part 8, which
supports the centre or axis e¹ upon which the lever K turns.
In the interior space A of this part, called the compressor, fitted to its FS face, and
supported by the above named knob or protuberance is the disc C, which has
likewise two apertures, one entire running right along the disc v, and another
partial opening not going right across the whole thickness of the disc, and
intended to admit the extreme point of the lever k, as shown at 1 This dise
rising and falling vertically, or moving excentric fashion, if the knob be fixed at the

page_text: side, adjusts (joins) or separates its orifice in front and in the direction of
communicating aperture 6", whereby it shuts off or opens the communication
between the compressor and the conductor, acting like a valve. This said disc is
fitted with a fixed knob f which acts as a butt against the stopper (TU²).
The conductor D or tube of communication between the compressor and the
regulator contains in its interior rod nothing but the lever K and the requisite
spindle rod U.
The regulator B, as already stated, is a pump barrel with its sucker Q joined to
the rod V.
This sucker does not fit accurately to the inside walls of cylinder B, leaving a
space, duly considered, in view of the gauge or measurement expected of the
apparatus. The mathematical accuracy of this measure is arrived at by introducing
into the inside of the sucker, which is hollow, a metallic body to increase the
weight of the sucker according to the required gauge. This sucker has an axis or
rod y adhering it, which works in, and is guided by, the ring like tubes M, M¹.
In this way the want of equilibrium in the sucker is avoided, and the gauging or
measuring is facilitated.
From the foregoing explanation it will be understood that the sucker of
cylinder B descends by its own weight until the rod V and the lover K reach the
bottom of tube D; then the extreme point of the lever, which impinges upon the
aperture of the disc C (which disc is placed inside of the compressor A), causes
said disc C to bring its aperture right opposite the communication orifice b¹¹,
thus giving the maximum influx of the liquid. This is shown in the first Figure,
which consequently presents the apparatus in its natural position before com-
mencing work, and the fluid, whether gaseous or liquid, entering through the
tube S will pass in freely through the pipes b, b', at right angles, thence through
orifice on to the aperture of communication ¹¹, next from the latter to the
conductor D, and from this to the regulator B in its upper portion, passing through
the space intervening between the outer wall of the sucker and the inner wall of
the regulator.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Tenth day of May, A.D. 1881.
