The end of the passage A Fig. 1 which is screwed inside or outside is connected
with the lowest part of a cask filled with the fluid to be devided in equal quantities.
The fluid enters the apparatus from A through the passage B and fills the space D.
E is a hollow tap movable but fitting fluid-tight into F Figs. 1, 2 and 3. By
turning the tap E, connection can be made either between the inlet passage. B and
the space D Figs. 1 and 3, or between the latter and the outlet passage j, the latter
connection being that shewn in Figs. 1 and 2. In the upper part of the space D
is arranged the piece O. By turning the contents of the space D may be
adjusted. Within O is arranged L and the valve k. L and are both firmly
attached to a thin spindle. L is either made hollow of thin metal plates or it is

properly guided in two points. Below L is arranged the disc N which serves for
guiding the valve-spindle and prevents the valve from falling too low.
It will be
seen that the valve itself never comes into contact with the fluid which is essential
for keeping the valve and its seat clean and tight.
From above the valve seat leads the passage u to a space which communicates
by the passage R with the atmosphere. The cover P. is firmly attached to the
tap E which may be turned by the handle S. v Fig. 4 is a pin preventing E from
being turned too far.
The action of the apparatus is as follows: After the tap E Fig. 1 is in the
position that the opening H Figs. 1 and 3 corresponds with the inlet passage B
Fig. 3 (the outlet passage G Fig. 2 being closed in this position) the fluid will rise
within the space D Fig. 1 and after having risen to a certain height will lift the
swimming piece L and consequently close the valve k. The air now being pre-
vented to escape farther from the space D. prevents the fluid from rising higher.
In this moment the tap E may be turned so that the outlet G corresponds with the
outlet passage; as shewn in Fig. 2. The valve lowering itself in this position
allows the admission of the atmospheric pressure which will cause the fluid to run
out through the passage j. The process described may be repeated and it will be
seen that the quantity of fluid running out through is always the same.
As
regards the weight of the swimming piece L it is most important that it, while
lifting itself by the rise of the fluid, it lowers itself again when the passage G
is opened; L must therefore have a certain weight which may be found by
experiment.
In Figs. 5, 6, 7 and 8 the cock is separated from the measure, the walls of the
latter being transparent, which has the advantage that the rise of the fluid
within D may be seen and controlled from outside.
B Fig. 5 is the inlet passage, j is the outlet passage, E is the tap with two
passages and h, S is the handle. L is a swimming piece (either solid or hollow)
k is a little ball valve and u and R are channels for the escape or admission of air.
This valve arrangement has the advantage that although the valve k is guided
just as perfectly as the valve k in Fig. 1, the guidances can never come into contact
with the fluid.
In the position shewn in Figs. 5 and 6 the fluid enters the space b through the
passages B, g and h and causes when risen to a certain height the lifting of L and
consequently the closing of the valve k. In this moment the handle S
may be
turned downwards in the direction of the arrow until the passage g communicates
with b and the outlet j. Then the valve k will lower itself and the contents of the
space D will run out through the passage j. Also in this arrangement L must
have a certain weight which I find by experiment.
I sometimes arrange the tap E so that while it is turned open by hand
(g making communication between b and j) it turns back into its former position
automatically by means of a weight W attached to the opposite side of the
handle S Figs. 5, 6 and 7.
A modified form of a cock shows Fig. 8. In this case the upper part of the
space D is arranged exactly in the same manner as shewn in Fig. 5 but the device
for controlling the outlet and inlet of the fluid is arranged as follows:
F Fig. 8 is a kind of cylinder within which the piston E moves fluid-tight.
The piston E is provided with two passages g and h. m is a spring by means of
which the piston is pressed back when moved by hand in the direction of the
arrow p. In the position shewn in Fig. 8 the fluid enters the space D through the
passages B, g and b. When the space D is filled, the piston E may be moved by
means of the button S in the direction of the arrow p. When h makes com-
munication between b and j the fluid will run out through j. This having taken
place, E will return by means of the spring m into its former position and the
space D will fill itself again.

page_text: 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
First. A cock with hollow tap, the latter serving as measure, in combination
with a valve and swimmer of a certain weight as and for the purposes herein before
described.
Second. A cock (or arrangement as shewn in Fig. 8) with a separate space D
(serving as a measure) in combination with a valve k and swiminer L (Figs. 5
and 6) as and for the purposes herein before described.
Third. To make the walls of the space D Figs. 5, 6 and 8 transparent that the
rise of the fluid within D may be observed and controlled from outside.
Fourth. A cock, or device as shewn in Fig. 8, constructed in such a manner that
while opened by hand, the tap or piston turns back into its former position by
means of weights or a spring, substantially as herein before described and shewn in
the accompanying drawings.
