Improvements in Apparatus for Controlling and Measuring Liquids.
I HEINRICH BÖRNER, of 46 Lutherstrasse, Berlin in the Kingdom of Prussia and
German Empire, Manufacturer, do hereby declare the nature of this Invention and
the manner in which the same is to be performed to be particularly described
and ascertained in and by the following statement :-
This Invention refers to an apparatus for controlling and measuring liquids, in
which by the opening of a cock one of two vessels is filled alternately with liquid,
such vessel closing automatically when filled to prevent waste, and in which when
the cock is turned into its other position the filled vessel is emptied and the empty one
again filled.
In order that my invention may be the better understood, I now proceed to describe
the same, in relation to the drawings hereunto annexed and to the letters and figures
marked thereon.
Figure 1 is a longitudinal section.
Figure 2 is a horizontal section according to the line I—I.
Figures 3 and 3 show the position of the four-way cock between the two measuring
vessels and one position of the air tap.
Figures 4 and 4* shew the relative position of the four-way cock and the air tap in
the other position.
Figure 5 is a plan of the counting gear used in the apparatus.
Figure 6 is a plan of the same from below and of the starting mechanism in one
position and
Figure 6 shews the other position.
The device for controlling liquids is arranged as follows:-
Between two measuring vessels B B' of any suitable shape is arranged a four-way
cock H, the channels of which communicate with the lower part of the vessels B B'.
For this purpose the vessels B B¹ have oblique bottoms.
The vessels B B are closed at the top by covers D D¹ having orifices 0 0', closed
by valves fixed to the upper ends of two floats S S'. Therefore if the level of
the liquid rises in one of the vessels B B¹ the float S or S¹ respectively is raised the
valve g or
gis placed against the orifice o or o', for which purpose the covers D D
are arranged as valve seats at the orifices o o', and the valves g g close the orifices o o'
against the liquid.
To ensure the more perfect prevention of the escape of liquids from the vessels BB'
they are provided with cylinders C C above the orifices o o¹. The cock H has a
plug K arranged for four-ways a, z, a, & x¹. The way leads to a short pipe which is
connected to the liquid reservoir by means of a flange f. The way a leads through a
connecting piece a a² to a further cock A the plug of which is supplied with a
handle A' for operating the measuring device.
The plug K is operated through turning the handle A', as the latter is connected to
a connecting rod y, pivotted at b to the transverse piece c, attached to the plug K.
The movement of the four-way cock is limited by the pin d.
When therefore the cock a is opened the plug K is placed so that the channel
communicates either with the vessel B or B and the channel a with the other vessel.
The operation of the cock A and the plug K respectively is indicated or transmitted
to the counting gear R at the commencement of working the plug K by means of the
double lever i turning around in and guided in a fork e of the transverse piece c by
which it is operated.

page_text: The upper end of this double lever i has a slot, in which is guided the pin m' of
a slide having teeth p¹.
Into these teeth p¹ of the slide p which slides to and fro on the lower surface of the
counting gear enters the projection g' of a double lever q to which it is attached
by an elastic arm. This lever is pivotted on a pin q² and operates the slide v
carrying a ratchet pawl by means of its fork q³ which grips the pin v' of the
slide v.
The spring like action of the piece 71 allows of the complete opening of the cock H
and complete movement of the slide by the lever i respectively.
The slide has two ratchet pawls o o opposite each other and gearing into the
opposite teeth of a ratchet wheel u which by means of suitable gearing transmits its
motion to the several dials of the counting device R.
When during the rotation of the plug K the lever i turns on its pivot the toothed
slide makes a corresponding movement. In this way and by the elastic double
lever the slide carrying the pawls is moved in one direction or another thus
inducing one of the two spring pawls o or o¹ to gear into the teeth of the ratchet
wheel while the other pawl slides over a tooth of the ratchet wheel u.
The movements of the double lever i and of the slide v are so regulated that during
the movement of the plug K from one position to the other, the ratchet wheel u is
moved forward to the extent of one tooth.
To facilitate the escape of liquid from a filled vessel B or B¹ when the float S or S¹
respectively closes the upper orifice o or o', a special air tap h is provided the plug k
of which is operated simultaneously with the plug K by means of the rod 1, thus
admitting atmospheric air to the emptying chamber.
The air tap is connected to the upper part of the vessel B B' by means of
channels nn and communicates at the corresponding position of the plug K with the
vessel B or B whichever is to be emptied. When then according to Figure 3 the
channel is brought into communication with the channel a of the vessel B and
therefor liquid is drawn from the vessel B through and a, the plug kopen on the
top, communicates through the channel n' with the vessel B' and is closed against the
vessel B see Figure 3. When on the other hand the channel is connected by a to
the vessel B' and the latter is filled and therefore the vessel B is also to be emptied
through and a, the plug k is connected to the vessel B by the channel n and closed
against the vessel B' see Figures 4 and 4".
.
The before described apparatus for controlling liquids may be modified, so that the
cock A is dispensed with and the liquid is drawn off direct through the pieces a¹ a²,
and it is designed particularly to measuring beer, wine, spirits, petroleum &c. and
may be made of any size.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed 1 declare that what
I claim is :.
1st. An apparatus for controlling and measuring liquids in which are arranged two
vessels B B connected to a four way cock K so that the entering liquid fills one of
the vessels while the other is emptied the vessels B B having in their upper parts
valves gg actuated by floats S S¹ to prevent overflowing of the liquid, in combination
with a counting mechanism R operated by the rotation of the plug K of the four
way cock by means of the double lever i, toothed slide p, elastic lever g and slide v
carrying ratched pawls.
2nd. In an apparatus for controlling and measuring liquids as claimed in claim 1
the arrangement of an air tap plug k worked from the plug K and which is connected
to the upper parts of the vessels B B¹ by means of channels n n' to facilitate the
drawing off of the liquid from the completely filled vessels B or B¹ respectively.
3rd. In an apparatus as claimed in claim 1 the operation of a counting mechanism R
by means of a slide p having teeth p' and operating the projection q₁ of the elastic

page_text: end of a double lever 9 thus working the counting mechanism in such a manner that
the latter is operated at the commencement of the movement of the slide p, while the
teeth pand the elastically attached projection q' allow of further movement of the
slide and consequent complete opening of the cock H.
