COMPLETE SPECIFICATION.
Improvements in Apparatus for Measuring and Retailing Thin
Liquids, such as Petroleum, Spirits, and the like.
We, GUSTAF MAGNUS NYSTRÖM, Manufacturer, and ASSAR CHRISTOPHER
LEMBKE, Manager, both of Malmö, Sweden, 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 relates to an apparatus for measuring and retailing thin liquids
such as petroleum, spirits, and the like in varying predetermined quantities in
shops or other places and has for its object to provide means whereby the gas or
alcohol is prevented from evaporating from the said liquids which evaporation has
heretofore taken place.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a vertical section of a complete apparatus and Fig. 2 a front view at an
enlarged scale of the measure or glass vessel constructed in accordance with our
invention and described for the storage, measuring and retailing of petroleum, but
which is also applicable for measuring and retailing other thin liquids.
In carrying out our invention the said apparatus consists of two receptacles a & b,
6 being placed upon a with its flange over the top a¹ of the bottom receptacle a
which flange may be reduced in size as far as the crown a to form a water joint to
prevent the escape of gases or bad smells. The upper receptacle b has two
bottoms c&d which form an intermediate space for the petroleum and keep the
latter at an equal pressure when being drawn off. In the bottom c is an opening
furnished with a funnel shaped strainer c' through which the petroleum, flows
from the upper receptacle b into the said intermediate space. In the bottom c is
also arranged a pipe c² which serves for the escape of the air driven from the inter-
mediate space by the out flowing petroleum. This pipe c³ reaches to the top of the
upper receptacle 6 which is covered by a lid 2.
The
The pipe g fixed in a part of the lid bª and in the bottom d supports a pump h,
the lower end of which reaches to the bottom of the lower receptacle a.
pump is loosely suspended from a spring h' so that it can be easily taken out of
h
the apparatus and so that after coupling to its delivery end an additional tube, it will
also serve to pump petroleum from a cask into the lower receptacle a, in which case
the pipe g forms a passage for the liquid and air. The cavity for the pump in the
lid 6 is closed by another lid f placed loosely upon a flange ƒº¹ a water joint being
formed between the two lids.
Three taps I, II and III positioned side by side communicate with the aforesaid
intermediate space, each of which taps has two passages of different size in
connection with corresponding pipes i & j, i the upper smaller one passing through
the wall of the larger one ; and reaching to the mouth of the tap. When turning
the latter two ports are opened or closed simultaneously. The small pipe i does not
communicate with the aforesaid intermediate space like the large pipe ; but is
connected to a pipe k which projects through the lower bottom d of the upper
receptacle and communicates with the lower receptacle a. The pipes & i are
passed jointly into a draw off arrangement which consists of a measure or glass
vessel m suspended at the side of the apparatus and in which the said pipes end at
different depths. The position of the ends of the first pair of pipes i, j, in the

page_text: measure or glass vessel m is equal to the level of a quantity of liquid therein
measuring two litres, that of the second pair equal to one litre and that of the third
pair equal to five deci-litres. It will be evident that by increasing the number of
taps other different quantities can be measured.
The bottom of the measure or glass vessel m is furnished with a tap n which
besides an ordinary outlet o is formed with a smaller one o'. The latter com:nuni-
cates with the atmosphere and has a pipe p reaching to the top of the measure or
glass vessel m which serves to admit air into the same when drawing off liquid.
The measure or glass vessel m is suspended from the tap pipes j and at the bottom
carried by two holders g springing from the side of the apparatus and ending in two
metal straps R which run to the cap 1 of the measure or glass vessel m.
these straps or on an independent one r are marks which indicate the different
levels of liquid. On the plugs of the different taps are also marked the different
measures.
On one of
In front of the apparatus is suspeuded a plumb the point of which must be
brought in line with a point fixed to the apparatus so that the apparatus will
always stand perpendicular. A piece of sheet lead is also attached on which the
correctness of the measures is certified.
The apparatus described works as follows:-
This
By means of the pump described the lower receptacle is filled with petroleum
from a cask and the petroleum is then pumped into the upper receptacle until the
same is full. By opening the taps which communicate with the intermediate space,
for instance the "one litre tap II" the petroleum will flow into the measure or
glass vessel m' until the level of petroleum has reached the end of the respective tap
pipe and is closed thereby. The air in the measure or glass vessel which so far
has escaped into the inner pipe i of the tap in action is bottled up and prevents the
petroleum in the measure or glass vessel rising higher thus giving time to close the
tap. If the tap is not closed immediately the petroleum will continue to flow from
the pipe j and flow back through the pipes i & k into the lower receptacle a.
creates an audible dripping sound which draws attention to the fact. Tap II is
then closed and the outlet tap n and thereby the air passage of opened whereby
just as much air enters, as petroleum flows out. The same takes place in the
apparatus itself. Each time the measure or glass vessel is filled with a quantity of
petroleum from the upper receptacle b a corresponding amount of air enters the
fower receptacle a through the pipes i, k. The two receptacles a & bare brought in
communication with each other through the space between the pump and its pipe g
in which it rests, so that the air entering the upper receptacle b, from which the
pretroleum flows, may escape through the same. By reason of this arrangement
the air pressure in the intermediate or closed space will always remain the same
until the last drop of petroleum has been drawn off which circumstances facilitate
a very reliable measuring and retailing of the petroleum.
In the same manner the apparatus will work for other thin liquids hereinbefore
indicated.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
1st. An apparatus for measuring and retailing thin liquids, such as petroleum,
spirits, and the like consisting of two receptacles a & b communicating with each
other, being placed onto a and rendered tight thereon by a water joint through
which receptacles is passed a pump, its upper end resting in a pipe 9 positioned in
the upper receptacle 6, its lower end extending to near the bottom of the lower or
proper liquid receptacle a from which the liquid is pumped to the upper receptacle b
as may be required, which latter at its lower end is furnished with a number of
outlet taps I, II, III, the outlet pipes j of which, reach different depths in a joint
measure or glass vessel m mounted at the side of the apparatus and provided at its
lower end with an outlet tap n having a liquid and an air passage o & o¹ respectively,

page_text: the measure or glass vessel m itself communicating through the upper taps and
their pipes i, k, with the lower receptacle a, all substantially as set forth.
2nd. In combination with the apparatus specified in the preceding claim, the
formation of a second bottom c in the upper closed receptacle 6 above the
taps I, II & III, which bottom is furnished with a strainer c¹ and receives an air
pipe c² leading from the intermediate space thus formed to the interior of the upper
receptacle 6 all substantially as set forth.
