Improvements in Apparatus for Weighing and Measuring the
Volume and Density of Bodies.
I, EDMOND CHAMEROY of 15 Rue Richelieu, Paris, in the Republic of France,
Manufacturer, 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 mechanism for measuring the volume or density of solid or
liquid matters of all descriptions. It is provided with runners carrying suitable
printing devices whereby the weight, volume and density of the bodies measured, as
well as the date of the measurement are stamped, or indicated in print. This
measuring machine moreover includes one or more stationary or movable dials
showing at a distance the weight or volume of the substances placed on the bridge or
platform of the weighing machine.
In order to enable my invention to be more readily understood I have illustrated
various modifications of it in the accompanying drawings, in which however only the
beams of the weighing machine are represented all the other parts being similar to
those of ordinary machines of the same description.
In these drawings ;—
Figs. 1 and 2 represent the beam of my weighing and measuring machine with a
double graduated lever integral therewith, and Fig. 3 shows a similar beam with two
independent graduated levers.
It will be seen that the beam A consists of two graduated bars or levers a barranged
one above the other; one of them a indicating units and fractions of units while the
other indicates tens, hundreds and thousands.
Upon each of these levers or bars a collar or runner a¹ b' respectively is arranged
to slide which runners may contain suitable printing mechanism or the like so
arranged as to be operated from outside if desired.

At the ends of the graduated bars or levers grooved pulleys p p and q are
arranged whereon flat or round endless bands ropes or cables a and y are passed,
which may be made of any suitable material and are respectively attached to the
opposite sides of runners a¹ and b¹, so that as these runners a¹ and I move they cause
a corresponding displacement of the bands x and y and the consequent rotation of
the loose pulleys p p and q q' on their respective shafts.
Upon or behind the runners a¹ and b¹ are situated receptacles c (Fig. 2) each
provided with a lid or cover with a bevelled inner surface as shown in Fig. 4 and a
tube or nozzle c' for the admission of the material either liquid or solid which it is
desired to measure or weigh.
Each of these receptacles may have a removable bottom screwed or otherwise
secured to the circular wall, or it may be fitted with a discharge tube c" for the
removal of the matters after the measurement is completed. The top tube or nozzle cl
may be made of glass and marked as shown at z Figs. 4 and 6 whereby is indicated
the limit up to which the receptacle should be filled so that it may in every instance
be filled up exactly to the same level. The receptacle e may be integral with the
runner, as shown in Fig. 4 or it may be independent of its runner and simply hooked
or attached thereto in the manner shown in Fig. 6.
In any desired point of each of the bands or cables x and y a counterweight al
and y' is placed so as to counterbalance the weight of the runners a' b¹ and of their
respective receptacles c when empty.
.
Opposite to the bars or levers a and b or in some cases below them I arrange a
third divided or graduated bar or lever e, on which moves a runner e¹. This
additional bar serves to counterbalance the weight of the receptacle placed upon the

page_text: bridge or platform of the weighing machine and destined to contain the matter it is
desired to weigh or measure.
Upon the spindle of each of the pulleys p q a plate or dial and k may be fixed as
shown in Figs. 1 and 2. These movable dials are marked with divisions similar to
those of the aforesaid graduated bars or levers a and b to which they correspond
respectively, so that the fixed index hands or pointers and will upon their
respective dials point to the same figures as those which their corresponding
runners a¹ and 6 show as they move along, so that the same figures may be read off
the dials as from the graduated bars or levers. Instead of fixing the said graduated
discs or dials hand to the spindles of the pulleys p and 1 may arrange them so
that they will be stationary and secure the pointers and k¹ upon the revolvable
shafts or spindles as in Fig. 3.
In the arrangement shown in Fig. 3 the two graduated bars or levers a and b are
independent of each other while the remaining parts are arranged in the same manner
as in Figs. 1 and 2 except the graduated discs or dials. Both graduated bars or
levers here are linked together by a bracket or supporting piece fitself supported by
a knife edge f arranged upon each of the graduated bars.
To get the figures indicating the weight or volume printed or stamped it is only
necessary as shown in Fig. 6 to insert a ticket o' into the opening o of the runners a
and and to firmly press such ticket against the lower portions of the graduated
bars a and b by means of the lever g; the figures being formed in relief upon the
lower edge of the said bars a and b in a manner corresponding to the vertically
visible divisions of the bar, so that the ticket o¹ thus receives an impression from
such projecting figures corresponding to the indication of the runner for the time
being.
Side by side with the printing mechanism which indicates the weights or measures,
I arrange within the runners a and another printing mechanism whose types of
figures are so arranged as to indicate the complete date. In order to enable this date
to be changed from day to day suitable external operating mechanism may be
provided.
To control or adjust the tension of the bands or cables and Ι arrange the
bearings and of the pulleys p¹ and q' in the manner shown in Fig. 5 so that these
bearings may be capable of displacement within the spaces n by the operation of
screws whereby the shaft w may at will be brought nearer to or removed farther
from the opposite pulley p or 9 as the case may be.
The operation is as follows:-
:-
(1) When a body is to be weighed or measured it is placed upon the weighing
bridge or platform in the ordinary manner, and, assuming that all the runners a
and care in their zero positions all that is necessary is to fill with water the
receptacle c of both the runners a¹ and 6' up to the marks of tubes c¹ and to adjust
the runners a¹ and upon their respective graduated bars so that the points or
indices uu take up their position opposite each other. The equilibrium being by
this time obtained the weight may be read off the graduated bars a and b or the
dials and k and an impression indicating the weight may be taken by inserting a
ticket o' into the slits or openings o of the runners a b'.
(2) When it is desired to ascertain the quantity of liquid or solid matter contained
in a receptacle or vessel of a given weight the runner e¹ is first moved upon the
graduated bar e so that the weight it indicates may correspond to that of the empty
receptacle. A certain quantity of the matter to be weighed is then taken (say a litre)
and placed in the receptacles c so that they are filled up to the marks. When this
is done the runners a' and b¹ are displaced in such a manner as to counterbalance the
receptacle placed upon the bridge or platform of the weighing machine. The figures
marked upon the graduated bars a and b or the dials h and k may then be read off
while the size or volume is stamped by means of the lever g upon the ticket o¹. It is
thereupen sufficient to add to these figures one litre (viz. the amount taken away at
the beginning of the operation) to ascertain the volume of liquid or solid material
contained in the receptacle placed upon the bridge or platform.

page_text: (3) When it is desired that a receptacle R should contain any given quantity of
matter say 455 litres the weight of the receptacle R is first to be ascertained by
conveniently displacing the runner el upon the graduated har e. Then the
receptacles c are filled with the matter which the receptacle R is to contain. After
this the runner is placed opposite the number 400 and the runner a¹ opposite the
number 55 when the receptacle R is filled with matter until the indices u u¹ are
opposite one another. When this occurs it shows that exactly 455 litres of matter
have been filled into the receptacle R.
(4) When it is desired to ascertain the density of the matter contained in a
receptacle R the weight of which when empty is known we first move the runner e
upon the graduated bar e in such a manner that it indicates the weight of the empty
receptacle R. When this is done a certain amount say one litre of matter is taken
from the receptacle R, then the receptacles c are filled with water and the weight of
the filled receptacle R is counterbalanced by a suitable displacement of the runners.
Let the number then indicated on the graduated bars be A. The receptacles c are
thereupon emptied and the water is replaced by some of the matter contained in the
receptacle R which matter is taken from the litre taken away at the beginning of the
operation. When the receptacles c are thus filled the receptacle R is counterbalanced
by a corresponding displacement of the runners a' and and another number say B
is read off. The density of the matter will then be found by the following relation
of the figures read off.

The method of grouping or combining in series the graduated bars or levers the
runners and the pulleys such as represented in the drawing may be varied at will so
long as the same purpose is attained viz;-the correct indication of the weight, size,
and density of the matter submitted to the test either on the said graduated bars or
upon the dials or a corresponding impression,-together with the date,-upon a ticket
of any convenient shape or size by means of printing devices fixed to the graduated
bars or arranged within the runners.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
-
1. A weighing and measuring apparatus whereby the weight, size and density of
bodies or matters may be ascertained characterized by a pair of graduated bars or
levers connected with or independent of each other and arranged either parallel to or

counterbalanced by a weight attached to an endless band or rope both ends of which are
connected with the rummers such rope passing over a pair of loose pulleys and with a
dial or graduated disc or plate mounted upon the shafts of the said pulleys or secured
to the said pulloys themselves and capable of indicating the weight and measurements
by a corresponding displacement of the runners and finally by a printing mechanism
also indicating the weights and measurements arranged either within the said runners
or upon the graduated bars the whole constructed and operating substantially as
described and illustrated in the drawings.
2. In a weighing and measuring apparatus indicating the weight size and density
