IMPROVED APPARATUS FOR MEASURING, CONTROLLING, AND REGISTERING JUICES
OF BEET ROOT, ALCOHOLS, AND LIQUIDS IN GENERAL."
My Invention consists in an arrangement of vessels of known capacity with
pipes for their supply, and discharge, governed by stop cocks or valves so com-
bined together, and with a registering apparatus, and also with sampling vessels,
that a record is automatically made of the volume and density of liquids, such as
juices of beet root, alcohols, or other liquors, the production of which in a manu-
factory has to be registered for excise or other purposes.
I will describe an arrangement in which I employ two measuring vessels, but it
is to be understood that a greater number of such vessels might be employed by,
simply repeating the apparatus connected with the two which I am about to
describe. A supply pipe leads to a two-way cock or valve, whence a. branch leads
to each of two vessels which are of equal and known capacity. From the bottoms
of these vessels two branch discharge pipes lead to another two-way cock or valve
on the main discharge pipe.
The supply cock or valve is connected by a spindle or rod to the discharge cock
or valve, so that when the supply is opened to the one vessel and closed to the
other, the discharge is closed to the former and opened to the latter, consequently:
the two vessels must necessarily be filled and emptied alternately.
The valve spindle or rod is worked by stops, so that it can only at any one movement
affect the one change of supply to and discharge from the vessels, and it is 'con.

From near the middle of each vessel a syphon pipe leads to a cock or valve on
a pipe leading to a sampling vessel. This cock or valve is connected to the supply

the height of the syphon bend, a sample of the contents drawn from near the middle,
and therefore of average density, flows to the sampling. vessel, which is provided
with two connected cocks or valves, the one giving a passage one-tenth or other
desired fraction of that given by the other, and a pipe from the smaller leads to a
vessel which inay be under seal. Thus whatever quantity may be drawn off by the
larger cock or valve for sampling by the workmen of the establishinent, a known

can thus ascertain the quantity and density of the whole liquid passed through
the apparatus.

"AN
FRANÇOIS DELORI, of Paris, Boulevard de Strasbourg, No. 23, Engineer.
IMPROVED APPARATUS FOR MEASURING, CONTROLLING, AND REGISTERING JUICES OF
BEET ROOT, ALCOHOLS, AND LIQUIDS IN GENERAL.”
My Invention consists in an arrangement of vessels of known capacity with
pipes for their supply and discharge, governed by stop cocks or valves so combined
together, and with a registering apparatus, and also with sampling vessels, that
a record is automatically made of the volume and density of liquids, such as juices
of beet root, alcohols, or other liquors, the production of which in a manufactory has
to be registered for excise or other purposes.
I will describe an arrangement in which I employ two. measuring vessels, but it
is to be understood that a greater number of such vessels might be employed, by
simply repeating the apparatus connected with the two which I am about to
describe. A supply pipe leads to a two-way cock or valve, whence a branch leads
to-each-of-two-vessels which are of equal and known capacity. From.the-bottoms
_of_these vessels-two-branch-discharge pipes lead to another two-way cock or valve
on the main discharge pipe.
€
The supply cock or. valve is connected by a spindle or rod to-the, discharge cock
-or valve, so that-when-the-supply-is-opened to the one -vessel and closed to-the
..other, the discliarge-is-closed-to the former and opened to the latter; consequently
the two vessels must necessarily be filled and emptied alternately.
The valve spindle or rod is worked by stops so that it can only at any one
movement effect the one change of supply to and discharge from the vessels, and it
is connected to a counter by which the number of such changes is registered.
Each of the vessels has a gauge to shew the level of the liquid in it, and is
provided with an air pipe leading to a discharge box, which may be under seal,

page_text: From near the middle of each vessel a syphon pipe leads to a-cock or valve on a
pipe leading to a sampling vessel. This cock or valve is connected to the supply
and discharge cocks or valves, so that it is always open to the vessel that is
receiving supply, and closed to that which is discharging. When the former
becomes filled to the height of the syphon bend, a sample of the contents drawn
from near the middle, and therefore of average density, flows to the sampling
vessel, which is provided with two connected cocks or valves, the one giving a
passage one-tenth or other desired fraction of that given by the other, and a pipe
from the smaller leads to a vessel which may be under seal. Thus whatever
quantity may be drawn off by the larger cock or valve for sampling by the work-
men of the establishment, a known fraction of liquid of. the same quality flows by
the smaller cock or valve, and is retained in a vessel for the examination of the excise;
or their official, who can thus ascertain the quantity and density of the whole liquid
passed through the apparatus.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a front view; Fig. 2, a plan; and Fig. 3, a side view of
measuring, controlling, and registering apparatus according to my Invention, having
two measuring vessels, of which the one is supposed to be removed in Fig. 3.
A,A, are the two vessels, which in distilleries may be quite closed, but in sugar
works might be open. B is the supply pipe; and C, the discharge pipe, each pro-
vided with a cock or valve D and E respectively, which are connected by a spindle
G, so that when the supply cock is opened to either vessel the discharge from the
same is closed. The spindle G, works in bearings in a framing F; to which the
cocks are fixed. The spindle is worked by a lever H, acting on it by a ratchet and
pawl, so that it can only be turned in the one direction one-quarter of a revolution
at a time. 1, 1, are branch pipes connecting the cocks with the vessels; K is a
counter of any known kind enclosed in a. case, and worked by the spindle G.
P, P, are air pipes to the measuring and sampling vessels. These air pipes should
be led into some closed or looked chamber above the apparatus. Q, are glass gauges
to shew the level of liquid in the vessels. These gauges might be extended down-
wards, and graduated to shew the volume of liquid.
By means of the apparatus so far described the volume of liquid supplied by the
pipe B and discharged by C can be readily ascertained.
For testing the density of the liquid the following details are employed:-Bent
siphon pipes S communicate with the measuring vessels at points R, about midway
in their height, and rise to nearly the level of their covers. They are provided with
small cocks or valves U, U, worked from the spindle G, so that while one of the
measuring vessels is filling the cock U on that side is open, the other being closed
whilst its vessel is emptying. Both pipes S lead to the sampling cock V, which is
worked by gearing X, Y, from the spindle G, and which communicates by a pipo
with the vessel T. This vessel has a discharge cock Z, which may be locked or
sealed, and which is connected by gearing to a smaller cock Z³, made of such area
of passage as to discharge 1/10th or other known fraction of the volume discharge by
Z. From this cock a pipe T' leads to a locked or sealed reservoir.
This testing apparatus is worked in the following manner:-When one of the
mensuring vessels A is filled, the siphon pipe S, belonging to it, becomes also filled,
and this constitutes a sampling charge retained in the pipe S by the closure of tho
cock V. When the spindle G is turned so as to reverse the supply and discharge of
the two vessels, the cock U of the charged siphon S is closed, but V is opened,
permitting the charge of the siphon to flow into T. From T a quantity of the
liquid is withdrawn from time to time to be tested for density by opening the cock
Z, but at the same time 1/10th or other known fraction of the quantity so withdrawn
is conveyed by the pipe T" to a reservoir, the measurement of the contents of which
can serve as a check of the total quantity withdrawn.
It is to be understood that in constructing apparatus such as I have described, all
the joints of pipes, cocks, or covers, should be made in such a way that they cannot
be tampered with, or that any tampering with them should furnish means of

page_text: detection. For this purpose, locks may be applied, or seals, or stamps in lead or
other impressible material.
The measuring vessels may be provided with overflow pipes, leading to closed
vessels, or with floats to work a bell or other audible alarin, so as to apprise the
attendant that they are filled. Also a cylinder caused; to revolve, or a strip of paper
caused to advance by clockwork, may receive marks from a pencil or other tracer
connected to the spindle G, so as to indicate the times of filling and emptying the
measuring vessels.
"Having thus described the nature of my Invention, and in what manner the
same is to be performed, I claim, the use for measuring and testing liquids of two
or, more measuring vessels, with connected cocks or valves for their supply and
discharge, in combination with a sampling vessel charged by means of siphon.pipes
and-cocks-or-valves therefore connected to those of supply and discharge, the
whole constructed and operating substantially as and for the purposes herein
set forth.
In witness whereof, I, the said François Delori, have hereunto set my hand
and seal, this Twenty-ninth day of October, in the year of our Lord One
