Improvements in Apparatus for Measuring and Registering !
Quantities of Liquid Drawn from Receptacles.
I, WILLIAM ANTON GOTTLIEB SCHONHEYDER, of No. 4 Rosebery Road,
Clapham Park, in the County of Surrey, Engineer, do hereby declare the nature
of this invention to be as follows :-
My invention relates to that description of apparatus wherein a vessel of:
definite capacity is adapted to be fitted to a main vessel or tank containing liquid,
and is provided with valve appliances whereby on the one hand the liquid is made
to pass from the tank into the measuring vessel so as to fill it while the air is.
allowed to escape from the latter, and on the other hand, the communication
between the vessel and tank being closed, the contents of the former are discharged;
while air is allowed to enter the vessel.
.
According to my present invention I construct such apparatus, as follows. A
vessel having a definite. capacity, and by preference of a conical or tapering form,
is arranged in a horizontal or slanting position and the one end being entirely:
closed, the other, open; end is fixed to a head piece which is provided with ports, :
passages and slide valves, arranged as follows. In the head are formed a large;
and a small valve chamber, separated from each other.
The large chamber. has firstly an opening in its side connected by a branch-
pipe with the reservoir or main vessel, so that the chamber is always filled with..
liquid, secondly two openings in its flat bottom face, communicating directly with
the measuring vessel, and thirdly an opening in its bottom, situated between the
two others and communicating with a passage formed in or under the said bottom į
face which leads to a discharge spout. On the faced bottom surface surrounding
these three openings, rests. a slide valve, which is kept at all times fluid-tight
against the face by the pressure of the liquid in the main tank, and which has a
cavity so formed that in one position it establishes a communication between the
one opening leading into the vessel and the opening leading to the discharge
spout, while at the same time its flange closes the second opening leading into the
vessel; in another position the valve uncovers the last named opening and closes
the communication between the other two, so that in the last named position the
valve allows the liquid to flow from the main vessel and valve chamber into the
measuring vessel, and in the first named position it prevents such flow and allows
the liquid with which the vessel is filled to flow off through the spout. The
requisite motion is imparted to the slide valve for this purpose by means of a
spindle with a crank handle passing through a stuffing box on the chamber, and
carrying a crank pin engaging with a socket in one end of the slide valve, so that
by the rotation of the crank pin the valve is brought alternately into the one or
other of the above named positions: A pawl and ratchet prevents the crank
from being turned backwards!'
.
At or about its middle the "slide valve is connected by a pin (passing through
one of the before mentioned openings) to the one end of a double ended lever that
is pivotted to the underside of the head; aud whose other end is connected by a pin
to a smaller slide valve contained, in the second before; mentioned chamber. This,
chamber also has three openings in its bottom surface,, two communicating with the
measuring vessel, and lone sittiated between thesortwo, communicating with at

page_text: passage leading to the outer air. The chamber has also a side opening communi-
cating by a passage and a suitable pipe with the main tank, above the level of the
fluid or it may communicate with the atmosphere. The slide valve of this
chamber is so formed that in one position it establishes a communication between
the one opening leading into the measuring vessel and the passage leading to the
open air, while in another position it closes this communication and uncovers the
second opening leading into upper part of the vessel or the atmosphere.
By the above described lever connection between the valves it will be seen that
when the large valve is moved into the position in which it admits liquid from the
main tank into the measuring vessel, the small valve will be in the last above
described position, in which consequently the air contained in the measuring vessel
can escape through the uncovered opening in the small valve chamber and through
the passage leading from the side of the latter into the main tank or atmosphere.
When, on the other hand, the main valve is moved into the position for allowing
the liquid to be discharged from the measuring vessel, the small valve is moved
into the position in which it establishes a communication between the vessel and
the passage leading to the outer air, so that air can now flow into the measuring
vessels so as to allow the liquid to flow out.
It will be seen that owing to its connection to the double ended lever the main
valve, when actuated by the crank pin, will receive a compound longitudinal and
lateral to and fro motion which will effectually prevent any grooving &c. of the
valve faces. And the small valve being circular and free to revolve is in a similar
manner prevented from grooving.
The air valve chamber has at its upper part an enlargement, the outer face of
which is closed by a glass disc behind which is a small float. When the measuring
vessel is quite full of liquid, this will also enter and fill the small valve chamber,
thereby causing the float to rise so that it will indicate to the attendant through
the glass that the vessel is full; when the vessel is discharged and filling has
recommenced, the small valve chamber will quickly empty itself into the measuring
vessel, thereby allowing air to escape as before mentioned and the float will fall
again.
The spindle actuating the main valve is connected by suitable gear to any known
form of counter for registering each successive discharge of the contents of the
measuring vessel.
The valves may be held on their seats by means of helical springs bearing on
the one hand against them and on the other hand against a sliding piece separate.
therefrom but travelling therewith and that bears against the inner top surface of
the valve chamber.

Improvements in Apparatus for Measuring and Registering
Quantities of Liquid Drawn from Receptacles.
I, WILLIAM ANTON GOTTLIEB SCHÖNHEYDER, of No. 4 Rosebery Road,
Clapham Park, in the County of Surrey, Engineer, 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 :-
My invention relates to that description of apparatus wherein a vessel of definite
capacity is adapted to be fitted to a main vessel or tank containing liquid, and is
provided with valve appliances whereby on the one hand the liquid is made to pass
from the tank into the measuring vessel so as to fill it while the air is allowed.to.

page_text: Fig. I shews a front view partly in section.
Fig. 2 shews a section on line X X.
Fig. 3 a section on line Y Y and
Fig. 4 a back view.
Fig. 5 shews a side view of the apparatus as attached to the measuring vessel
and tank.
A casing A containing a large valve chamber B and a small one C, is attached
to a measuring vessel D of conical or tapering form as shewn so as to facilitate the
discharge of liquid and air, the casing or head A being fixed to the vessel D by
the circular face A' Fig. 4.
The large chamber B has firstly an opening E in its side communicating by a
passage E and pipe E with the tank F containing the liquid, of which measured
quantities are to be discharged; by means of the said pipe and passage conse-
quently the chamber B is always kept full of liquid. Secondly this chamber has
in its flat bottom B' two openings G G communicating directly with the measuring
vessel D, and between these, another opening G2, communicating with a passage G³
leading to a discharge spout H,
On the faced bottom surface surrounding the openings G G G2 rests a slide
valve I, which is kept at all times pressed fluid tight upon the said face by the
pressure transmitted from the head of liquid in the reservoir to that in the
chamber B.
This valve has a cavity 1' so formed that in one position of the valve it
establishes a communication between the openings G₁ and G2 so that liquid can
flow off from the vessel D through the discharge spout H, while at the same time
the flange I of the valve closes the opening G; this position of the valve is
shewn in the lower half of Fig. 1. In another position shewn in the upper half
of Fig. 1 the valve I uncovers the opening G, so that liquid can flow from the
tank F through the chamber B into the measuring vessel while the flange of the
valve closes the communication between G' and G2.
The requisite motion is imparted to the valve for bringing it into either of these
positions, by means of a spindle J passing through a stuffing box in the cover A²,
which is turned by a suitable key or crank handle, and which has a crank on its
inner end the pin J of which enters a socket in the valve flange 12. Thus by the
motion of the slide valve the measuring vessel D is alternately filled with a definite
quantity of liquid from the tank and has that quantity discharged.
The slide valve carries a pin K extending inwards through the opening G¹ and
connected to one end of a double ended lever L pivotted at L' to the inner side
of the casing A and having its other shorter arm L2 pivotted to a pin M carried
by a second slide valve N contained in the second chamber C. This chamber also
has three openings in its bottom face, namely two O, O', communicating with the
vessel D, and a third 02 communicating with a passage 03 leading to the open air
(Fig. 4).
The chamber C also has a side opening-P leading to a passage P₁ communi-
cating with a pipe Q leading up through the tank F to above the highest level of
the liquid therein. Or the passage P₁ might merely open to the outer air.
The slide valve N has a cavity N' which, in the position shown in lower part
of the chamber C Fig. 1 establishes a communication between the openings.
and O2, and consequently puts the vessel D in communication with the outer air,
the opening O¹ being at that time closed by the flange of the slide valve.
When brought into the position shown in the upper part of chamber C on the
other hand, the valve uncovers the opening O', and consequently puts the vessel D
in communication through passage P¹ and pipe Q with the upper air space in the

page_text: tank F, the communication between the openings O and O³ being then cut off by
the valve.
By the above described lever connection between the valves I and N it will be
seen that when the valve I is moved into the position in which it admits liquid
from the main tank into the measuring vessel, the valve N will be in the last above
described position, in which consequently the air contained in the measuring
vessel D can escape through the uncovered opening O¹ in the valve chamber Č
and through P and Q into the main tank. When on the other hand, the valve I
is moved into the position for allowing the liquid to be discharged from the
measuring vessel, the valve N is moved into the position in which it establishes
a communication between the vessel and the passage 03 leading to the outer air,
so that air can now flow into the measuring vessel so as to allow the liquid to
flow out.
It will be seen that owing to its connection to the double ended lever L the
valve I when actuated by the crank pin J will receive a compound longitudinal
and lateral to and fro motion which will effectually prevent any grooving &c. of
the valve faces. And the small valve being circular and free to revolve is in a
similar manner prevented from grooving.
The valve chamber has at its upper part an enlargement C¹ the outer face
of which is closed by a glass disc R behind which is a small float S. When the
measuring vessel D is quite full of liquid, this will also enter and fill the valve
chamber thereby causing the float S to rise so that it will indicate to the
attendant through the glass that the vessel is full, when the vessel is discharged
and filling has recommenced the small valve chamber will quickly empty itself
into the measuring vessel, thereby allowing air to escape as before mentioned and
the float will fall again.
The spindle J actuating the valve I is connected by suitable gear to any known
form of counter for registering each successive discharge of the contents of the
measuring vessel.
The valves may be held on their seats by means of helical springs T T
bearing on the one hand against them and on the other hand against a sliding
piece T T separate therefrom but travelling therewith and that bears against
the inner top surface of the valve chamber.
When it is not desired to discharge the air from the measuring vessel D into
the tank F, the slide valve chamber C slide valve N and lever L can be dis-
pensed with, and the upper part of the measuring chamber be simply provided
with an air pipe leading up to a height above that of the level of the liquid in
the storage tank.
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. In apparatus for measuring and registering quantities of liquid drawn from
receptacles, the combination with a measuring vessel of a casing or head con-
taining firstly a slide valve and ports whereby the lower part of the said vessel
can either be put in communication with a tank or reservoir of liquid so as to
be filled therefrom, or be cut off therefrom and have its contents discharged, and
secondly a slide valve and ports whereby the upper part of the vessel can either
be put in communication with the air space of the reservoir or with the outer air,
the said two slide valves being connected by a lever so that when the first named
valve is in the position for filling the measuring vessel, the second valve is in
position for discharging the air therefrom, and when the first named valve is in
position for discharging the contents of the measuring vessel, the second valve is
in position for admitting air thereto, substantially as described.
2. In apparatus for measuring and registering quantities of liquid drawn from
receptacles, the combination with a measuring vessel of a slide valve chamber
such as B having a passage E E' leading to the main tank, two ports G and G¹

page_text: communicating directly with the said vessel, and a port G³ communicating with a
discharge passage, and a slide valve, such as 1, actuated by a crank spindle or
other device from the outside, and so arranged that in one position it opens the
port G so as to admit liquid into the measuring vessel and closes the communi-
cation between the ports G¹ and G³, while in another position it closes the
port G and opens the communication between ports G' and G2 for discharging
the contents of the vessel, substantially as described.
3. In apparatus for measuring and registering quantities of liquid drawn from
receptacles the combination with a measuring vessel of a slide valve chamber
such as C having ports 001 communicating directly with the said vessel, a
port O communicating with the outer air, and a port P P leading to the air
space of the main reservoir, and a slide valve such as N, so arranged that in one
position it opens the port O' so that the air can escape from the measuring
vessel into the main tank during the filling, while in another position it closes
the said port and opens the communication between ports O and O2 so as to
allow the outer air to enter the measuring vessel during the emptying substantially
as described.
4. Apparatus for measuring and registering quantities of liquid drawn from
receptacles, combined and operating as herein described with reference to the
accompanying drawings.
