PROVISIONAL SPECIFICATION.
Improvements in or connected with Machinery for Pumping Raising
or Forcing Liquids.
I REGINALD CZERMACK of Teplitz, in the Province of Bohomin in the Empire
of Austria, Manufacturer do hereby declare the nature of this invention to be as
follows:-
:-
The improvements forming the subject of this invention relate to that class of
pumping machinery which is fitted with ball-valves and the object of the improve-
ments is both to avoid the existence of incompletely filled spaces in the suction
and force or delivery pipes, and to render all the ball-valves, at the same time,
readily accessible; so that such valves, together with their seats, muy be quickly
cleansed, changed and repaired.
The first-mentioned object is attained owing to the position in which the suction
and force pipes and the pump cylinder or barrel are arranged with relation to the
valve chest or chamber; whilst the last mentioned object is accomplished by tho
provision of a valve-chest cover or lid, common to all the valves, and adapted to be
opened and closed by means of a hand-wheel mounted on a spindle.
In the accompanying drawings in which a ball-valve pump, provided with a
water tank and embodying the present improvements, is represented by way of
example,
Figure 1 is a side elevation of the machine partly in section.
Figure 2 is a top-view or plan thereof with the valve chest shown in horizontal
section and
Figure 3 is an end elevation thereof partly in scotion.
In the several figures like parts are indicated by similar letters of reference.
As shown in the drawings the pump-gear, located within the water-tank A,
consists of the valve-chest or chamber G, which a vertical partition divides into
two compartments, each of which contains two superposed valve-seats for the
ball valves r, and these two compartments laterally communicate between the
superposed valves with open pump-cylinders, C and C' respectively.
The two compartments of the valve-chest or chamber are connected with one
suction pipe S common to both located beneath them and with which is connected
an exhaust or vacuum air chamber W fitted with a cock H, in the well known
manner; whilst at the top, the two compartments of the valve chest communicato
with the force or delivery pipe S', also provided with an air chamber Wand con-
trolled by cocks H'.
Owing to this arrangement of the suction and force or delivery pipes, the
existence of incompletely filled spaces is effectually obviated inasmuch as the water
brought by the rising piston or plunger K into the suction pipe S, by raising also
the valves in the corresponding compartment of the valve chamber completely
fills such compartment as well as the space underneath the same whilst the other
piston or plunger which at the same time descends, causes the whole of the con-
tents of that compartment of the valve chamber connected with the cylinder of
such plunger to pass away into the force-pipe S'.

page_text: The valve-chest or chamber G is provided with openings closed by covers or
lids & opposite the several valves.
These lids d are screwed to or mounted upon one common carrier plate D
adapted to be advanced or retracted by turning a hand-wheel 1 fixed on a screw-
spindle P; working in a nut P by which means upon turning the hand wheel R
in one or the other direction the lids or covers d of all the valves will be simul-
taneously opened or closed so that all the valves are thus rendered easily accessiblo
at the same time.
In the case of pump mechanism arranged within a water-tank, the screw
spindle Pas shown in the drawings passes through the wall of the tank und, for
the purpose of reliably guiding the carrier-plate 1), together with the lids d
attached to it, parallel guide rods are provided, supported at one end by the
valvo chest or chamber and at the other, by the wall of the tank.
Where the pumps are arranged outside the water tank the guide-rods F lastly
referred to may be dispensed with, and the nut P' wherein the adjusting screw I'
is arranged to turn, may be carried by a suitable bearing, secured to the valve-
chest or chamber.
Improvements in or connected with Machinery for Pumping, Raising
or Forcing Liquids.
I, REGINALD CZERMACK of Teplitz in the Province of Bohemia in the Empiro
of Austria Manufacturer do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
The improvements forming the subject of this invention relato to that class of
pumping machinery which is fitted with ball or clack-valves and the object of the
improvements is both, to avoid the existence of incompletely filled spaces in the
suction and force or delivery pipes and to render all the ball valves at the same
time readily accessible so that such valves together with their seats, may be quickly
cleansed changed and repaired.
The firal-mentioned object is attained owing to the position in which the suction
and force-pipes and the pump cylinder or barrel are arranged with relation to
the valve chest or chamber whilst the last mentioned object is accomplished by
the provision of a valve-chest cover or lid common to all the valves, and adapted to
be opened and closed by means of a hand-wheel mounted on a spindle.
Referring to the drawings accompanying my Provisional Specification in which
a ball or clack valve pump. provided with a water tank, and embodying the present
improvements is represented by way of example.
Figure 1 is a side-elevation of the machine partly in section.
Figure 2 is a top-view or plan thereof with the valve chest shown in horizontal
section, and,
Figure 3 is an end elevation thereof partly in section.
In the several figures like parts are indicated by similar letters of reference.
As shown in the drawings, the pump-gear, located within the water-tank A,
consists of the valve chest or chamber G, which a vertical partition divides into
two compartments. each of which contains two superposed valvo-seats for the ball
or clack valves v and these two compartments laterally communicate-between the
superposed valves-with open pump cylinders C and C', respectively.

page_text: The two compartments of the valve chest or chamber are connected with one
suction pipe S, common to both located beneath them and with which is connected
an exhaust or vacuum air chamber W fitted with a cock H in the well known
manner whilst at the top, the two compartments of the valve chest communicate
with the force or delivery pipe S' provided with the usual air chamber W' and
controlled by cocks H'.
Owing to this arrangement of the suction and force or delivery pipes, the
existence of incompletely filled spaces is effectually obviated inasmuch as the
water brought, by the rising piston or plunger K, into the suction pipe S by raining
also the valves in the corresponding compartment of the valve-chamber, com-
pletely fills such compartment as well as the space underneath the same whilst
the other piston or plunger. which at the same time descends, causes the whole of
the contents of that compartment of the valve chamber connected with the cylinder
of such plunger to pass away into the force-pipe St.
The valve-chest or chamber G is provided with openings closed by covers or
lids d opposite the several valves.
These lids d are secured to or mounted upon one common carrier plate D
adapted to be advanced or retracted by turning a hand wheel R fixed on a screw
spindle P. working on a nut P by which means upon turning the hand-wheel R
in one or the other direction, the lids or covers d of all the valves will bo simul-
taneously opened or closed so that all the valves are thus rendered easily accessible
at the same time.
In the case of pump mechanism arranged within a water-tank the screw
spindle P-as shown in the drawings-passes through the wall of the tank; and.
for the purpose of reliably guiding the carrier-plate D, together with the lids d
attached to it, parallel guide rods are provided supported at one end by the
valve chest or chamber and at the other by the wall of the tank.
Where the pumps are arranged outside the water tank, the guide-rods Flastly
referred to may be dispensed with, and the nut 1" wherein the adjusting screw P
is arranged to turn may be carried by a suitable bearing, secured to the valve
chest or chamber.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In pumps controlled by means of ball or clack valves, a divided valve chest
or case (, the two compartments or chambers of which contain, each, two super-
posed valves, while communicating below with one common suction pipe S and
at the top with the common force pipe S¹; and being each connected-between the
valve seats with one of the two open pump-cylinders C C substantially as shown
and described and for the purpose stated.
2. In pumps arranged in the manner stated in the preceding claim, a valve
chamber closing device, enabling the compartments of the valve case or chest G,
corresponding to the several valves, to be all opened or closed at the same time,
and consisting of a plate D carrying the lids d of all the lateral valve orifices,
adjustable by means of a screw spindle P and hand wheel R; such plate in the case
of pump-mechanism arranged within a water tank-being guided between rids
such as F, substantially as shown and described and for the purpose stat :d.
