Improvements in Apparatus for Delivering Measured Quantities of
Liquid and Registering the Deliveries.
We, MAX SCHRÖTER, Manufacturer, and IZRAEL CHAIM PRASZKIER, Merchant,
both of 114, Piotokowska-Strasse, Lodz, Poland, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention has reference to apparatus for delivering measured quantities
of liquid and registering the deliveries.
The improved apparatus hereinafter described, while being of most simple and
easy manipulation, allows of exercising a strict control over the liquid which
has to be delivered, whether into one vessel or it may be several at a time.
Further it allows of determining at any desired moment the weight of the liquid
still remaining in the reservoir or main container.
This latter advantage is of very great practical value in the case of that class
of liquids whose coefficient of expansion is not only very considerable, so that
they vary greatly in volume with variations of temperature, but which liquids
also possess the property that their coefficients of expansion at the same time vary
with the temperature and density, the result of which is that the deduction of
weight from volume cannot be effected without taking other matters into account,
but necessitates the employment of tables and tedious computations.
Apparatus constructed in accordance with our invention is represented in various
modifications in Figs. 1 to 3 of the accompanying drawings.
The counter or indicator o which registers the flow of the liquid from the
apparatus is actuated by the float A through the intermediation of any suitable
transmitting mechanism.
The mechanism for this purpose represented in Fig. 1 comprises the screw
spindle 7, toothed gearing D D and spindle t. The float. A is provided with an
internal female thread and carries two projections n n working in corresponding
slots so that the float cannot itself rotate, but in rising and falling sets the
spindle in rotation, this motion being communicated to the toothed wheels D D¹,
spindle and the pointer of the counter o by bevel gearing as shown.
.
The transmitting mechanism represented in Fig. 2 comprises the following
arrangement of parts. The float A is secured to one end of a cord, or it may
be a small chain, 7, which passes over pulleys D1 and D2 to a pulley D3 which
actuates the indicator o; all these three pulleys are fast on their spindles, which
consequently rotate with the pulleys during motion of the float. After passing
round the pulley D³ the cord is led to the pulleys D and D5, which are situated
behind the pulleys D2 and D' respectively, and upon the same spindles, but
running loose thereon; both these loose pulleys are therefore free to rotate on
their spindles (in the opposite direction to the latter). The other end of the
cord 7 is connected to a counterweight G which balances the float A.
It will be evident that any other suitable transmitting mechanism may be
employed for communicating the movements of the float to the indicator. For
example, the cord passing from the float A to the counterweight & may go

page_text: round only one pulley and actuate the counter o through the intermediation of
the spindle of such pulley, another pulley fixed thereon, an endless chain, and a
pulley fixed on the spindle of the indicator o.
In all cases the float and also the mechanism for transmitting the movements
thereof, are shut off from the liquid in the liquid reservoir W by the pipe R in which
said float works or the chamber R in which said mechanism is contained. The
counterweight is also preferably suspended in a special pipe R2 (Fig. 2) which
if desired may also be situated in the pipe R, without however being connected
thereto. The pipe R communicates with the liquid container W through a small
pipe provided with a cock Q. To empty the float chamber R, either the cock Q
(the plug of which must in. this case be suitably bored, see Fig. 2) may be
employed, or a special cock Q¹ (Fig. 1) may be provided. In this latter case
the communication between Wand R should be adapted to be closed when
desired by a cock Q as shown in Fig. 1.
In order that the control shall extend not only to the liquid passing out
through R, but also to that remaining in the reservoir W, either of the arrange-
ments represented in Figs. 1 and 2 and which we will now describe may be
employed.
In Fig. 1 the float in its rise simultaneously actuates two different indicators,
which are so calibrated, that while the one indicates the quantity of liquid flow-
ing into R from the main container W, the other indicates the quantity remain-
ing in the container W. If however the communication between W and R is
to be interrupted as described by the cock Q2 and the liquid allowed to flow out
from R through Q', this latter indicator must first be thrown out of gear in
order that the indication of the quantity of liquid remaining in the container W
shall not be affected by the sinking of A. With this arrangement however
there is the drawback that at the commencement of outflow of the liquid from R,
the indicator concerned viz., that showing the quantity of liquid delivered (which
indicator is not adapted to be thrown out of gear) does not stand at the zero
point of the scale, so that the actual quantity of liquid allowed to flow out can
only be arrived at by subtraction.
This drawback is avoided by the arrangement shown in Fig. 2.
In this arrangement instead of two cocks Q1 Q2 as shown in Fig. 1 a single
cock Q is employed adapted to be operated by a handle H, the plug of this cock
is suitably bored so that according to the position of the handle H the pipe R
is put either in communication with the liquid container W or with the out-
flow pipe U.
Upon the spindle of the counter o, in addition to the fixed pointer (not shown
in the figure) which indicates upon two concentric scales the quantity of liquid
flowing into R and out of R, there is loosely suspended another pointer 1, which,
by reason of the weight 2, is normally maintained vertical (that is stands at
zero). On both sides of this loose pointer upon the same spindle are two small
discs 3 and 4, of which 3 is fast on the spindle and 4 is movable longitudinally
thereon. Between these two discs is interposed a spring 5, which is in com-
pression and tends to maintain them apart. The adjustable disc 4 is adapted
to be actuated by the upper arm 6 of the rocking lever 6, 7, 8, the lower arm 8
of which is pulled towards the wall of the liquid container W by the draw
spring 9. By moving inwards the arm 12 of rocking lever 10, 11, 12 and thus
overcoming the pull of spring 9. the arm 8 of the lever 6, 7, 8, can be moved.
away from the wall of W and the end of arm 6 will then force the disc 4 against
dise 3, so that the pointer I will be gripped between 4 and 3 and compelled to
follow the rotation of the pointer spindle. The movement of the indicator will
thus, as will be readily understood, always commence from the zero point of
the scale.
Care must be taken that the pointer 1 is always securely gripped while the
liquid is allowed to run from the pipe R. This is attained by providing that
on putting the handle H into the position shown in Fig. 2 it comes against the

page_text: lower arm 12 of the lever 12, 11, 10 and forces same towards the wall of the
liquid container W. The upper arm 10 of lever 10, 11, 12 will thus be moved
away from the wall as above described, and at the same time the upper arm 6
of the lever 8, 7, 6 will force the disc 4 against 3, and the pointer will remain
gripped between these dises until the cock Q is turned off, when the arm 12 will
be released and the spring 5 will force the disc 4 away from the disc 3. 7 and 11
indicate the pivotting points of the levers 6, 7, 8 and 10, 11, 12.
Now it is frequently of importance to provide that the liquid shall only be
allowed to issue from the pipe R partly, that is in quantities at a time, and in
definite quantities. For this purpose the following arrangement, shown in Fig. 2
will serve.
The small pipe is adapted to be closed by a conical plug e which is secured
to a rod f. The rod f is partly square as shown, and its lower (or square) end
works in a guide g, while its upper part, which is threaded, works in the hollow
rod, which is formed with a corresponding internal thread at its lower end.
Upon rotation of the hollow rod h, the rod f, which in consequence of the guide g
cannot rotate with same, must either move upwards or downwards.
Upon the hollow rod is a bevel wheel which is connected with a special
counter o through the intermediation of the bevel wheel, spindle d, pulley D6,
and cord or chain t. Further, the plug e is subject to the action of the motion
of the float A, this being effected in the following way:-
To the pulley D is secured a bevel wheel y¹ which can be put into gear with
the bevel wheel y³ on the hollow rod through the intermediation of the bevel
wheely, which is adapted to be put into and out of gear by the lever s.
In order to effect the desired partial delivery of the liquid from the pipe R,
the train of wheels y', y², y3 is first thrown out of gear by the lever s and the
plug e so to speak wound up" by means of the crank and the mechanism t
Dedahf (this winding up being determined by the indication of the
counter ). The wheels yyy are then put in gear and the liquid allowed
to flow off through the pipes and ; the float A sinks and its movement is
transmitted by the mechanism 7, 1)¹, D², y', y2 y3, h, f to the plug which at
the proper moment namely when the desired quantity of liquid has been delivered
from the pipe I, automatically closes the pipe and prevents further escape of
the liquid from R.
The above described apparatus can obviously be multiplied; that is to say several
pipes R can be employed with one container W, these pipes all communicating
with W by means of small pipes such as r. In this case the connecting pipes
would be adapted to be closed by means of cocks all arranged to be opened and
closed by a common rod. One of the pipes R would be provided with a float
actuating a counter through the intermediation of transmission mechanism.
Such an arrangement of apparatus as this would allow of filling in a very exact
and certain manner, as many vessels, say bottles, at a time as there are pipes R
in communication with the container W.
All the above described arrangements possess the advantage that they can be
applied to any reservoir of liquid for example to an ordinary cask; this has not
been possible with hitherto known apparatus of the kind in question. For this
purpose it is only necessary to insert the pipe R (together with R R2 and the
other mechanism) in the head of the cask in a fluid tight manner and to connect
it with the latter by a narrow pipe such as and provide an exit opening. In
other words, while in the hitherto known apparatus the calibration of the inte-
grator had to be reckoned with reference to the entire container, the counter
has here only to correspond to the pipe R which is capable of being disconnected
and can be applied to any liquid container.
Apparatus of the kind last described is shown in Figure 3 the float, transmitting
mechanism and counting devices not being shown.
In the cylindrical container W is an open ended pipe R' which surrounds an
interior movable cylinder R. Cylinder R communicates by a disconnectible

page_text: tube ¹µl with the container W. The parts, each of which is provided
with a cock (g' q respectively) can be brought together or separated from each
other, this being effected by the piper being provided with an outer pipe Cmovable
longitudinally thereof, adapted to enter the pipe, and in this way unite r
and to form a single passage. which movements can be effected either directly
by hand or by mechanisin P.
In order to use the apparatus the cylinder R is first so placed that its lower end
is at the same level as the bottom of the liquid container. The sliding pipe C
is then pushed into the pipe to connect R with W, and the cocks q and q
are opened. Consequently the liquid levels in the two containers will become
coincident. If the relation of the cross sectional area of W (pipe R being
excluded) and R equal n, then the volume of liquid remaining in W will be n
times as great as that in R, and therefore in order to arrive at the entire quantity
of liquid, inclusive of that in R, it is only necessary to multiply the latter
by (n+1). If the weight of the liquid in R be known, the entire weight can be
obtained by the same simple reckoning, since both quantities always remain in
the same proportion.
If it be desired to obtain the weight of the cylinder R, the cocks q1 and q11 are
first closed, C and are pushed apart, the support M is drawn out and R allowed
to sink on to the balance x. The run-off pipe u provided with a cock K allows
of delivering the liquid from the cylinder R.
It will be obvious that the arrangements above described and shown in Figures 1
and 2 can be applied with that last described (Figure 3) in one and the same
liquid container, and may even be inserted in the same pipe R.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what'
we claim is :-
1. In apparatus for delivering measured quantities of liquid and registering
the deliveries, the combination of a pipe or chamber adapted to be connected to
the liquid reservoir, a float such as A working in said pipe or chamber, a counter
or indicator adapted to register the quantity of liquid delivered at each operation
of the apparatus, and mechanism for transmitting the motion of said float to
said counter or indicator, all substantially as described and represented in
Figures 1 and 2 of the accompanying drawings.
2. In apparatus of the kind specified in Claim 1 the combination with the
registering device of a special pointer such as 1 loose on its spindle, and which
by means of devices such as 3 and 4 and levers such as 6, 7, 8 and 10, 11, 12 is
automatically gripped and actuated every time the outflow of the liquid from the
float chamber begins and at the end of such flow resumes the zero position, sub-
stantially as described and shown in Figure 2.

liquid to be delivered at one operation of the apparatus and which plug upon
the outflow of the liquid from the float chamber sinks under the action of the
float and mechanism such as (1, D1, D2, y', y², y³, h, f, c) whereby the motion
of the float is transmitted to the said plug and at the moment previously deter-
mined by the setting of same closes the outflow pipe all substantially as described,
and represented in Figure 2.
