Improvements in Pulsometers.
I, JOHN REID of No. 1 Ladeira São Bento Rio de Janeiro Brazil, Profession,
Mechanical Engineer, do hereby declare the nature of this invention, to be as
follows:-
This Invention has for its object improvements in pulsometers...
The improved pulsometer is provided with a steam moved piston valve controlling
the admission of steam. The construction is preferably as follows:-the body of the
pulsometer consists of two chambers rectangular at the lower part and at the upper
part tapering or of funnel like form and terminating at the top in an aperture for the
admission of steam.
Each of these working chambers is furnished with a suction and a delivery valve
and is provided near the top with a small vent fitted with a regulating valve.
The upper apertures of the working chambers communicate by passages with the
interior of a cylindrical valve chest, on either side of a disc valve.
This valve is contained in a cavity within the valve chest and whilst the apparatus
is at work steam is admitted to this cavity by opening a steam cock provided for the
purpose. The disc valve resting at one end of the cavity bars the passage for the
steam in this direction but leaves it free to pass out of the cavity at the other end and
thence into one of the working chambers of the pulsometer.
Around
In starting the apparatus the disc valve is moved to and fro in the cavity by hand
by means of a handle connected with the valve rod but when the apparatus is in
regular work the movement of the valve takes place automatically. To effect this two
pistons are provided on the rod of the disc valve one on either side of it and the
cylindrical valve chest is lined with brass where these pistons work within it.
each piston an annular groove is formed and there is a small steam port through the
side of the cylinder in which the piston works; this when the piston is at the outer
end of its stroke (which is very short) corresponds with the groove in the piston.
Perforations in the piston allow the steam to pass from the groove through the piston
and into the outer end of the cylinder. The pressure of this steam accumulating in
front of the piston presently drives it to the other end of its stroke revorsing the

page_text: position of the valve. When the piston is in its new position the groove in it comes
to correspond with another small port through the cylinder side and by this the steam
previously admitted to the cylinder escapes. Then by the like action of the cylinder
and piston on the other side of the disc valve the position of the valve is again
reversed and so on continuously. Regulating cocks are provided upon the pipes
which admit steam to the cylinders and also on the pipes in connection with exhaust
ports by which the steam finds exit from the cylinders.
The disc valve directs steam first into one body chamber of the pulsometer and then
into the other. The admission takes place when the chamber is full of water and the
steam drives the water out through the delivery valve and so away to the place where
the water is required to be delivered. Whilst the chamber is thus emptying through
tho delivery valve a portion of the water passes out by a small jet pipe into the other
chamber in the body of the pulsometer which at this time is filled with steam. The
condensation of this steam is thus brought about and a vacuum is formed. The suction
valve thus opening admits water into the chamber and by the time it has filled the
change in the position of the disc valve occurs, steam is in turn admitted to this
chamber of the body of the pulsometer and the water is driven out from it into the
delivery pipe.

In order that my said invention may be more fully understood and' readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical transverse section of an apparatus constructed according to
my invention.
Figure 2 is a horizontal section on the line 1-1 Figure 1.
Figure 3 is a vertical longitudinal section on the line 2-2 Figure 1.
Figure 4 is a vertical transverse section of the valves to a larger scale.
Figure is a vertical longitudinal section.
Figure 6 is a plan, and
Figure 7 is a horizontal section of the same.
a a are the two chambers of the pulsometer each of them is furnished with a
suction valve a¹ and a delivery valve a², near the top is a small vent fitted with
a regulating valve a³-the upper apertures of the working chambers a communicate by
passages with the interior of a cylindrical valve chest having the disc valve e centrally
in it. As is shown this valve is contained in a cavity within the valve chest. Steam
is admitted to the cavity by the steam pipe & Figures 4 and 7. This steam pipe is
fitted with a throttle valve shown in elevation in Figures 1 and 4. The disc c is
mounted upon a rod e furnished at one end by with a lever handle e' by which it can be
moved to and fro. The rod e also carries two piston valves ff these piston valves are
perforated with holes as is clearly seen in Figures 5 and 7. These holes f¹ f¹
lead from grooves around the piston valves (see Figure 5) to hollows on their outer faces
(see Figure 7). At the end of each stroke of the the groove in one or over valve of the
holes comes opposite to the a holes in the cylinder leading to the one
extremities of the steam pipe provided with a cock g' (see Figure 5) and at the other
end of their stroke the same valve groove comes opposite to the holes /¹ h¹ leading
from the cylinder to the exhaust pipe (see Figures 6 and 7) by which the exhaust
steam is leil to the space between the other valve f and the dise c.
The action of the pulsometer is as follows:-
The steam being opened to the piston valve by means of the throttle valve d' the
steam passes through one of the outlet ports thence to one of the chambers a.
After the steam has flowed to this chamber for the space of two or three seconds, the
throttle valve is closed and the valve e is pulled over to the opposite seating by means
of the hand lever e' this being done the throttle valve is reopened supplying steam to
the opposite port thence to the other chamber a. After the steam has flowed for
the space of another two or three seconds into this chamber the throttle valve is
reclosed and the valve c moved to the other seating as before. This being repeated
for two or three times the chambers a will be filled with water, then the throttle valve
is opened allowing the steam to pass through the port which is opened thence to the
chamber discharging the water that this contains when water is discharged the
cylindrical valve is pulled over thus admitting steam to the other chamber, discharging
the water therein at the same time injecting a jet of water to the opposite chamber by
the jet tubes which are placed at bottom of the same chambers this causing the
condensation of the steam therein producing a vacuum and thus filling the chamber
with water by the time the other is emptied.

page_text: The cock then can be opened allowing steam to pass through one of the pistons
ports which is open to steam consequently forcing the valve c to the opposite
seating giving steam to the other chamber a and discharging the water therein and
injecting a jet of water as before to the other chamber the steam then being open to
the other piston port, will force the valve over to the other seating as soon as tho steam
is exhausted from the opposite piston by the exhaust pipes h h and so continue its
automatic motion as long as it is supplied with steam and water to pump.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I do not claim generally the use of steam moved valves in connection with pulso-
meters or the valves Tf separately and apart from each other but I declare that what I
claim is :-
1. The piston valves ff whose perforations f¹ fl at one end of the stroke come
opposite to steam admission ports and at the other end of the stroke to exhaust ports
substantially as described.
2. The combination of the dise valve c with the two perforated piston valves fj
substantially as described.
3. The combination of the lever e¹ rod e and valves ff and c so that the apparatus
can be started by hand substantially as described.
4. My improvements in pulsometers substantially as described.
