PROVISIONAL SPECIFICATION.
An Improved Steam Pump of the class known as Pulsometers.
I AUGUST BRÜGGEMANN of Breslau, Germany, Engineer do hereby declare
the nature of this invention to be as follows:-
The improved steam pump of the class known as pulsometers, according to my
invention is constructed substantially in the manner shewn in the accompanying
drawings and consists of the regulator head K, two working chambers a and b,
condenser sieves s, suction valves, pressure valves ³; and wells g.
The action of the pulsometer is as follows: When the steam inlet valve is opened,
and the regulator is in the position shown in drawing, then steam enters regulator
head K, through channel 1, and fills the slide chamber, which, by means of slide d,
is partitioned into the 3 compartments 2, 6, and 7.
In the position shewn, compartment 2 is connected with compartment 6 by means
of channel 5 and slit c, while chamber 5 is shut off from compartment 7 by means
of the stroke check h and connection with said compartment can only take place
through slit c.
The steam then enters chamber b through steam channel 3 and forces the liquor
therein contained through a pressure valve 2 into the pipes.
When the water level has gone down sufficiently for the steam to penetrate into
the enlargement e of chamber then the working steam quickly condenses and
especially so when it comes into contact with the metal sieve s which is here
placed.
In consequence of the said steam condensation a sudden decrease of pressure
takes place in chamber and therefore also in compartment 2 and 6 of the regulator.
In this way over pressure will arise in compartment 7, whereby slide d is reversed
and steam channel 4 is opened to working chamber a, simultaneously with which
valve v3 opens, allowing water or other fluid to be sucked from well g through
opening o' to chamber b, whereby complete condensation of steam in chamber b
takes place and this chamber becomes filled with liquid, air entering at the same
time through opening o' of valve v³, the quantity of such air being regulated by
partly covering openings o² with a slide t.
When chamber is filled with liquid again, which coincides with the liquid being
driven out of chamber a as far as enlargement e, then the afore described action
for reversing slide d is repeated in the opposite order, while suction valve v² in
chamber 6 closes up and suction valve 2 of chamber a comes into action. These
processes are now continuously repeated as long as the steam inlet remains open.

COMPLETE SPECIFICATION.
An Improved Steam Pump of the class known as Pulsometers.
I, AUGUST BRÜGGEMANN of Breslau, Germany, Engineer, 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 :-
The improved steam pump of the class known as pulsometers, according to my
invention is constructed in the manner illustrated in the drawings, accompanying
my Provisional Specification; and consists substantially of the regulator head K,

page_text: two working chambers a and b, condenser sieves s, air or fluid or liquid valves v³,
suction valves v², and wells 9.
The action of the apparatus is as follows:-
When the steam inlet valve is opened, and the regulator is in the position shown
in drawing then steam enters regulator head K through channel 1, and fills the
slide chamber, which by means of slide.d is partitioned into the three compart-
ments 2, 6, and 7.
In the position shown, compartment 2 is connected with compartment 6, by means
'of channel 5 and slit e, while chamber 5 is shut off from compartment 7 by means
of the stroke check h, and connection with said compartment can only take place
through slit c. The steam then enters chamber through steam channel 3 and
forces the liquor therein contained through a suction valve into the pipes.
When the water level has gone down sufficiently for the steam to penetrate into
the enlargement e of chamber b, then the working steam quickly condenses, and
especially so when it comes into contact with the metal sieves which is here
"placed.
In consequence of the said steam condensation, a sudden decrease of pressure
takes place in chamber and therefore also in compartments 2 and 6 of the regulator.
In this way over pressure will arise in compartment 7, whereby slide d is reversed,
and steam channel 4 is opened to working chamber a, simultaneously with which
valve opens, allowing water or other Huid to be sucked from well g, through
opening to chamber, whereby complete condensation of steam in chamber b
takes place, and this chamber becomes filled with liquid, air entering at the same
time through opening of valve ³, the quantity of such air being regulated by
partly covering openings o2 with a slide t.
When chamber is filled with liquid again, which coincides with the liquid being
driven out of chamber a as far as enlargement e, then the afore described action for
reversing slide d is repeated in the opposite order, while suction valve ² of chamber a
comes into action. These processes are now continuously repeated as long as the
steam inlet remains open. The arrangement and construction of the discharge or
delivery valves may be the same as in ordinary pumps of this kind.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
"
The invention of "An improved steam pump of the class known as pulsometers
substantially as hereinbefore set forth and described and illustrated by the
accompanying drawings.
