PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Measuring or Drawing off Liquids.
I, HANS BERGER, Kaiserin Augusta Allee. 15 and 16 Berlin, N.W., in the
Empire of Germany, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention for improvements in apparatus for measuring or drawing off
liquids relates to apparatus in which the measuring vessel is placed below the
container so that when the two vessels are put in communication, the liquid
readily flows from the container to the measuring vessel; and has for its object
to provide a controlling arrangement which shall automatically regulate the flow
of liquid to the measure, in such manner that during the drawing off, any flow
of the liquid from the container is prevented, but when the measure is emptied
and the draw-off closed, the flow is allowed to proceed until the measure is
refilled.
!
According to this invention an opening in the bottom of the container com-
municates with the measuring vessel situated below it, and a similar opening in
the bottom of the measuring vessel forms the draw-off opening. Each opening
is fitted with a valve having a vertical rod suitably guided and extending above
the top of the container, the valve rod of the draw-off valve passing for this purpose
through a tube in the container which tube also admits air to the measuring
vessel. An operating lever is pivotally connected with the upper ends of the
valve rods such lever being weighted at one end and at the other provided with
a chain or cord. The weighted end of the lever is arranged adjacent to the draw-
off valve rod, and in the normal position closes the draw-off opening by pressing
the valve down on its seat. The weight continues to descend by gravity after
the valve rod has reached its lowest position, causing the lever to rotate about
the pivotal support on the upper end of the draw-off valve rod, and thus raise
the container valve rod and its valve from its seat. The valve being normally
held in this position, it will be seen that the measuring vessel is in communica-
tion with the container and is thus filled with liquid ready to be drawn off. The
drawing off is effected by pulling down the free end of the lever with the chain or
cord, the container valve rod being first forced down, and when in its lowest
position forming a fulcrum about which the lever is rotated to raise the draw
off valve which allows the liquid to flow out for use. When the chain or cord
is released the weighted lever returns the parts to their normal position.

I, HANS BERGER, Kaiserin Augusta Allee, 15 & 16, Berlin, in the Empire of
Germany. 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:-
This invention for improvements in apparatus for measuring or drawing off
liquids relates to apparatus in which the measuring vessel is placed below the
container so that when the two vessels are put in communication, the liquid
readily flows from the container to the measuring vessel; and has for its object
to provide a controlling arrangement which shall automatically regulate the flow
of liquid to the measure in such manner that during the drawing off, any flow
of liquid from the container is prevented, but when the measure is emptied
and the draw-off closed the flow is allowed to proceed until the measure is
're-filled.
The apparatus is illustrated in section in the accompanying drawing. A is a
reservoir of any kind for use with liquids, throughout which runs a pipe E, open
at the top and bottom. The reservoir has also an outlet in the bottom which
can be closed by means of a suitable cone, ball, or other valve G. The valve G
is actuated by a rod D projecting through the top of the reservoir and surrounded
with a cone or basket like contrivance N or equivalent apparatus for guiding and
stopping it. Below the reservoir A the measuring vessel B is placed. The
size of this corresponds to a given quantity of the liquid which it is desired to
draw off. The vessel B is furnished with an outlet provided with a pipe J. The
outlet is closed by means of any suitable valve which is also restricted in its
movement, and is fixed to the rod F which passes freely through the pipe E
and extends above the large container A. Both the valve rods D and F are
attached to a lever C pivoted at L and M above the container A. On the one end
of this lever is a weight K on the other a cord or chain 0 which is pulled when
the measuring vessel is to be emptied. The lever C when in the position of rest
has its support in the pivot M and thus keeps the valve H closed being prevented
from turning back completely by the stop N. By means of the weight K the
valve rod D is raised and the outlet of the reservoir opened in the direction of the
vessel B.
The working of the apparatus is as follows:-The vessel A being filled with
liquid and the lever C being in the position of rest, the valve H is closed and the
valve G opened as shown; thus, as the air can pass freely from the measuring
vessel B by means of the pipe E liquid flows into the measuring vessel B until
it is filled: The level of the liquid in the pipe E rises as high as in A, whereupon
the supply ceases of itself. If, now, the chain O be subsequently pulled the
noint L is lowered so that the valve G is closed by means of the valve rod D and
the connection hetween the reservoir A and the measuring vessel B is broken.
The lever then rotates further on the pivot L, M is raised and the outlet at H.
in the measuring vessel B is opened. The contents of B now flow out, as the air
can pass through the pipe E into the vessel B. When the chain is released the
lever C will rotate around L until, by the seating of the valve Hits pivot is
at M and turning still on this, opens the valve G so that B is again filled out
of the store in A.
In order to precisely adjust the contents of the measuring vessel B the pine .T
can be made to screw in. whereby the volume of the liquid flowing out of B is
correspondingly lessened

in regard to its movement.
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. Apparatus for the automatic measuring of definite quantities of liquid, in
which the measuring vessel is placed below the reservoir, the distinguishing
features being a lever, which when the apparatus is used, moves around a pivot
until the measuring vessel is shut off from the reservoir, but thereupon, moves
around a second point serving as a pivot, and after employment of the apparatus,
being actuated by a weight, moves around these two pivots in inverted order; and a
pipe running through the reservoir from top to bottom, and serving as an outlet
and as a guide for a valve rod connected with the lever.
2. The improved apparatus for the automatic measuring of definite quantities
of liquid, substantially as described with reference to the drawings.
