I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the valves of what are ordinarily
known as pulsometers by means of which it is possible to raise 70 kilogrammes of
water to a height of 9 metres with one atmosphere of steam pressure and with
considerable economy of fuel.
The steam admitted in the usual way through an upper valve enters a cap or
cover and surrounds an inner main valve which is screwed between the flanges of
the cap and the pulsometer itself and is covered with a fine sieve so that no dirt,
suspended in the steam, can enter the valve below. The steam then passes through
an opening above in the body of a main valve to a cylindrical valve and round the
latter alternately to one and the other chamber of the pulsometer, the water being
drawn from a supply pipe by the condensation of the steam in one chamber which
is momentarily closed by the cylindrical valve whilst in the other chamber the
water already drawn up is simultaneously forced up in a delivery pipe.
The right side of the body of the main valve is freely moveable and is guided
laterally the steam passing in drives this side of the valve to the right for a short
distance then passes round the hollow cylindrical valve into one of the chambers,
turning the valve over at the same time. By the moving of the side piece of the
main valve, a suspended weighted rod is moved from its vertical position, and
afterwards brings back the moveable side of the main valve by swinging back with
an adjustable set screw against the vertical surface of the fixed part of the valve
a continuous opening and closing of the body of the valve being thus effected,
whereby the cylindrical valve between them is turned over from side to side at the
same time.
Each steam chamber has on its under end an inclined pipe, which has at each end
a suction valve and a delivery valve. Both inclined pipes are connected above and
below by a junction pipe to a suction pipe and a delivery pipe, so that by the
alternate suction and pressure in the two chambers, a continuous suction in the
suction pipe and a continuous pressure in the delivery pipe are caused.
The right inclined pipe is connected with the left chamber by a tube which is
provided in the chamber with a rose covered with a fine sieve. This tube is
provided with a cock which serves to regulate the admission of water or to stop it.
In the same manner the left inclined pipe is connected with the right chamber by
a pipe which also has a rose inside and a cock outside. The steam pressing in one
of the chambers the water through the delivery valve forces at the same time
some water through the corresponding tube, which causes the condensation of the
steam in the other chamber and leads to the suction through the suction valve
and vice versa. In the moveable part of the body of the main valve are screwed
two set screws which can come against the face of the fixed part of the main
valve, if they are screwed out, so as to regulate adjustably the movement of the
moveable part of the valve.
To each chamber of the pulsometer is screwed upon the flange of the body of
the main valve an air valve which is provided with an adjustable weight which opens
and allows the admission of air at a determined pressure of the atmosphere. For this
purpose the valve rod is made of square section, so that the air can enter between

page_text: it and the circular bore and through the opened valve, as soon as the external air
lifts the rod.

Improvements in Pulsometers.
A communication to me from ARMAND WLOCH, of Namslau, in the Empire of
Germany, Engineer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention and in. what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement and accompanying drawings, that is to say:-.
This invention relates to the improvements in the valves of what are ordinarily
known as pulsometers by means of which it is possible to raise 75 kilogrammes of
water to a height of nine metres with one atmosphere of steam pressure, with
considerable economy of fuel.
In the accompanying drawing
Figure 1 is a longitudinal section of the improved pulsometer, Figure 2 a front
view, Figure 3 a longitudinal section at right angles to Figure 1, and Figure 4a
plau.
The steam is admitted through an upper valve into the cap A, and enters the
rectangular slot C between the two parts of the valve scat and moves the loose
part D of the same to the right as far as the pendulum G allows, according to
the height of the steam pressure. If the pressure is low the valve seat part D¹ is.
only moved for a short distance and if the pressure is higher, then the part. D¹ is
moved through a greater distance, so that when the pressure falls, the pendulum G
brings the moveable part D' nearer to the fixed part D, and when the pressure is
steady the pendulum G remains in the same position, but the circular valve E goes
from one side to the other, closing one chamber, and opening the other chamber of the
pulsometer, into which the steam enters, pressing down the water, and then when
the condensation commences as presently described sucking the valve E to this side
and closing it, steam then entering the other chamber, pressing down the water
and as the steam condenses, sucking the valve E to this side, a movement which is
assisted by the steam pressure.
On the face of the moveable part D¹ of the valve scat are screws R, Figure 1
which can be screwed out more or less, to obtain a more or less small space between
the valve seat D and the moveable valve seat part D' to allow the steam to cuter
between them.
The pin F of the pendulum G is fastened to the fixed part of the valve seat D,
and the pendulum carries on its upper arm a screw H, for adjusting the position of
the pendulum G, Figure 3. The moveable valve seat part D' is guided in the
part Dand has sufficient room on the right side, for it to move backward and
forward.
The whole valve seat is covered with a fine sieve B, which prevents the dirt,
suspended in the steam from coming into the valve.
Each steam chamber has on its under end an inclined pipe, which has at cach
end a suction valve J and a delivery valve K, both inclined pipes are connected
above and below by a junction pipe L to a suction pipe M and a delivery pipe N
so that by the alternate suction and pressure in the two chambers, a continuous
suction in the suction pipe M and a continuous pressure in the delivery pipe N are
causerl.

page_text: The right inclined pipe is connected with the left chamber by a tube O which is
provided in the chamber with a rose, covered with a fine sieve. This tube O is
provided with a cock P, which serves to regulate the admission of water or to stop
it. In the same manner the left inclined pipe is connected with the right chamber
by a pipe Q, which also has a rose inside and a cock P outside.
The steam in one of the chambers pressing the water through the delivery
valve K forces at the same time some water through the corresponding tube O
or Q, which causes the condensation of the steam in the other chamber and leads
to the suction through the suction valve J and vice versa. In the moveable part D¹
of the body of the valve D are screwed two set screws R which can come against
the face of the fixed part of the valve D, if they are screwed out, so as to regulate
adjustably the moveable part D' of the valve.
To each chamber of the pulsometer is screwed upon the flange of the body of
the valve D an air valve S which is provided with an adjustable weight T which
opens and allows the admission of air at a determined pressure of the atmosphere.
For this purpose the valve rod U is made of square section, so that the air can
enter between it and the circular bore and through the opened valve V, as soon as
the external air lifts the rod U with the weight T, which may be filled with zinc
or lead and may weigh about 135 grammes.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:
-
1. Above the chamber of a pulsometer the arrangement of a valve D, whose
part D is moveable and encloses with the other part D the hollow cylinder E,
which closes alternately both chambers, according as the part D' is opened or
closed by means of the suspended weight rod.
2. Over the suction valves J of the pulsometer, the arrangement of the cross
tubes O and Q in the chambers to effect the condensation of the steam and the
suction by injecting the water.
3. Underneath the valve D the arrangement to each chamber of an air valve S
which is weighted with the adjustable weight T.
