Martin, No. 162, Paris, Manufacturer, for the Invention of "AN
IMPROVED REGISTERING, CONTROLLING, AND WEIGHING MACHINE."
Scaled the 16th July 1875, and dated the 6th March 1875.
PROVISIONAL SPECIFICATION left by the said Edme Augustin
Chameroy at the Office of the Commissioners of Patents, with his
Petition, on the 6th March 1875.
I, EDME AUGUSTIN CHAMEROY, of Faubourg St. Martin, No. 162, Paris,
Manufacturer, do hereby declare the nature of the said Invention for
"AN IMPROVED REGISTERING, CONTROLLING, AND WEIGHING MACHINE," to be as
follows:-
The weighing of goods on ordinary balances or weighing machines
often gives rise to errors, because the weight has to be read off directly
from the beam without any mark being preserved by which it can be
verified; in fact, a verification can only be obtained by weighing a
second time. This drawback would be entirely prevented if at the time

machine itself could be obtained; and this is the object of my present
Invention.
According to one modification of my Invention, which I will describe
as applied to platform scales, a flat steel or brass bar is fixed to the
under side of the scale beam, and is engraved in relief with figures indi-
cating the weight of the goods.
bar and on the beam, and carries
a ticket or card rests. Below the
provided with a handle.
The movable weight slides on this
below the bar a small plate, on which
plate is a cam, the axis of which is
The operation of the machine is as follows:-The goods to be weighed
having been placed on the platform, the movable weight is shifted on
the beam until an index on the beam is on a level with a fixed index,
that is to say, until a true balance has been obtained. The weight can
then be read off in the usual way from the indications on the beam.
Then to obtain a printed indication of the weight the ticket is slipped
under the engraved bar, the cam is then turned by means of its handlo
so as to lift the small plate, and the ticket is thus caused by pressure to
receive an impression of the figures corresponding to the weight. The
cam handle is then lowered and the ticket withdrawn.
When the weighing has been effected the movement of the beam may
be prevented by a hinged stop.
The printing of the ticket might also be done by the means generally
adopted for printing railway tickets; or in the damp way followed in
numbering bills or warrants; or, in some cases, the figures indicating the
weight, instead of being engraved on the beam, may be arranged on
rotating discs representing units, tens, and hundreds; these discs would
be fixed at one point to the machine, and be operated by the travel of
the sliding weight on the beam; or the advance of the weight on the
beam could be effected by an endless screw, or a toothed wheel, or a steel
band on an axle, which at the same time works the numbering discs of
the weight.
For weighbridges with two beams, or for balances with two sliding
weights, the application of these several modes will be the same. It will
suffice for each weight to have a system of printing, the figures of which
would arrange themselves below one another on the tickets, so that they
may be readily added,

page_text: th
According to another arrangement I employ several weights, say
three, of different values, and fixed on separate and parallel sliding bars.
One weight would be, say, 10 lbs.; another, 1 lb.; and the third,
1/10 lb. On the under side of the bars is a series of notches, say 10 on
each bar, and on the upper side is a set of projecting figures, one
opposite each notch. These figures represent on each bar the numbers
0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Each bar has a handle by which it can be
lifted. On the upper side of the scale beam is a knife edge, on which
one notch of each bar rests. Above the bars is a block having an up-
and-down movement in a frame, the downward movement being given
by pressing upon a knob, and the upward movement by a spring. The
weights with their bars slide on rails or guides on the scale beam.
The action of this controlling weighing machine is as follows:-After
having "tared" the machine the notches of the-several bars must bo
placed on the knife edge, so that the figures 0 may be opposite and tho
weight indicated be 0. The machine in this first position is in equili
brium, that is to say, the movable index and fixed index are exactly
opposite cach other. If goods to be weighed be then placed on the
platform, and it is required to obtain a printed record, the way to
proceed is as follows:-
-
First. Try if by pushing the first weight of 10 lbs. on the first bar a
notch is found which corresponds approximately to the weight; it being
understood that the figures indicated on this first bar represents 100 lbs.
cach. Suppose, for example, that the bar placed at the figure 3 was too
licavy and at figure 2 it was too light, the goods would therefore weigh
more than 200 and less than 300 lbs.
Second. Proceed in like manner with the second bar, which represents
tens, and it will be found at, say, the figure 3, which will signify that
the weight is less than 240 lbs. but more than 230 lbs.
Third. Proceed in like manner with the third bar, which represents
units, and the exact weight will be obtained, say 237 lbs.
The machine now shewing by its indexes that the exact weight has
been ascertained, the movable stop is raised so as to prevent movement
of the machine. The knob above mentioned is then pressed down so as
to cause the block to impress on the ticket the figures representing the
weight. These figures will be found side by side, and can therefore bo
casily read.

page_text: I may remark that it is always necessary to bring the bars into the
notches, because there would not otherwise be figures opposite to give
tho impression of the weight.
I have described the application of my Invention to a platform
weighing machine but no difficulty will be found in adapting it to an
ordinary balance, or to a weighbridge for heavy loads, or to a steel-
yard.
The tickets printed by the machines may be made to shew on one side
the gross weight, and on the other the tare; also the date and the
number of the machine.
Instead of weights sliding in the usual way on the beam I may use
weights moved in a circular direction at the ends of arms or radii turning
in a vertical plane. On the axis on which these arms turn are keyed
stop ratchets and sectors provided with figures for printing on tickets,
as above explained.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edme Augustin Chameroy in the Great Seal
Patent Office on the 31st July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDME
AUGUSTIN CHAMEROY, of Faubourg Saint Martin, No. 162, Paris, Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

tion for "AN IMPROVED REGISTERING, CONTROLLING, AND WEIGHING MACHINE,'
upon the condition (amongst others) that I, the said Edme Augustin
Chameroy, my executors or administrators, by an instrument in 'writing
under my, or their, or one of their hands and scals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edme Augustin Chameroy, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had
to the accompanying Drawings, that is to say:
The weighing of goods on ordinary balances or weighing machines.
often gives rise to errors, because the weight has to be read off directly
from the beam without any mark being preserved by which it can be
verified; in fact, a verification can only be obtained by weighing a
second time. This drawback would be entirely prevented if at the time
of weighing a printed record of the weight produced mechanically on the
machine itself could be obtained; and this is the object of my present
Invention, and of the several arrangements herein-after described.
The first arrangement or modification of my Invention, which I will.
describe as applied to platform scales, is represented in Figures 1 to 4,
Figure 1 being an elevation; Figure 2, a transverse section; and
Figure 3, a longitudinal section; while Figure 4 is a view of the under
side of the beam.
A is the platform on which the goods to be weighed are placed; B,
the frame of the machine; C, the movable beam; D, the part con-
necting the beam C with the movement of the platform A; E, the
movable index on the beam; and F, the fixed index on the frame; G is
a flat steel or brass bar fixed to the under side of the beam C, and
engraved in relief with figures indicating the weight of the goods; His
the movable weight which slides on the beam C, and carries below the
bar a small plate J, on which a ticket or card I (shewn separately in
Figure 5) rests; below the plate. J is a cam K, the axis of which is pro-
vided with a handle L.

page_text: The operation of the macbine is as follows:-The goods to be weighed
having been placed on the platform A, the movable weight H is shifted
on the beam C until the index E is on a level with the fixed index F,
that is to say, until a true balance has been obtained. The weight can
then be read off in the usual way from the indications on the beam.
Then to obtain a printed record of the weight the ticket I is slipped
under the engraved bar G, the cam K is then turned by means of its
handle L so as to lift the plate J, and the ticket I is thus caused by
pressure to receive an impression of the figures corresponding to the
weight. The cam handle L is then lowered, and the ticket I with-
drawn.
When the weighing has been effected the movement of the beam may
be prevented by a hinged stop M.
The printing of the ticket might also be done by the means generally
adopted for printing railway tickets; or in the damp way followed in
numbering bills or warrants; or, in some cases, the figures indicating
the weight, instead of being engraved on the beam, may be arranged on
rotating discs representing units, tens, and hundreds; these discs would
be fixed at one point to the machine, and be operated by the travel of:
the sliding weight H on the beam C; or the advance of the weight on
the beam could be effected by an endless screw, or a toothed wheel, or a
steel band on an axle, which at the same time works the numbering
discs of the weight.
:
'
For weighbridges with two beams the application of these several
modes will be the same.. It will suffice for each weight to have a system
of printing, the figures of which would arrange theniselves below one
another on the ticket, so that they may be readily added.
Again, there could be arranged in the interior of the movable weight H
and on the same plane as the beam C a steel plate having the units 0
to 9 indicated by lines or marks engraved in relief, which would be
impressed on the ticket at the same time as the figures of the beam. In
this case the figures representing teus are followed by a small line a.
The ticket impressed in this way is represented in Figure 11. The
Figures 2 and 7 are marked by the beam, and indicate by the line a that
the Figure S should be taken as the unit, as shown by the corresponding
linc.

page_text: Figures 6 to 10 represent another arrangement, in which I employ
several weights, say three, of different values, and fixed on separate and
parallel sliding bars. The same letters of reference apply to parts cor-
responding to those represented in Figures 1 to 4. V is the tore of the
machine; J, J, J, are the parallel bars provided with weights; H is a
weight of, say 10 lbs., on the bar J; H', a weight of 1 lb. on the bar J';
and II, a weight of 1/10th of a pound on the bar J. On the under side of the
bars is a series of notches L, L, L, say ten on each bar, and on the upper.
side is a set of projecting figures K, one opposite cach notch L.
figures represent on cach bar the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Each bar has a handle N, N¹, N, by which it can be lifted. On the
upper side of the scale beam O is a knife edge P, on which one notch L
of cach bar rests. Above the bars is a block Q, having an up-and-down
movement in a frame T, the downward movement being given by
pressing upon a knob R, and the upward movement by a spring S. The
weights with their bars slide on rails or guides on the scale beam.
These
The action of this controlling weighing machine is as follows:--After
having "tared" the machine the notches L of the several bars J, J', J³
must be placed on the knife edge P, so that the figures 0 may be opposite
and the weight indicated be 0. The machine in this first position is in
equilibrium, that is to say, the movable index E and fixed index Fare
exactly opposite each other. If goods to be weighed be then placed on
the platform, and it is required to obtain a printed record, the way to
proceed is as follows:—
First. Try if by pushing the first weight II on the first bar Ja
notch Lis found which corresponds approximately to the weight, it being
understood that the figures indicated on this first bar represent 100-lbs..
cach. Suppose, for example, that the bar placed at the figure 3 was too
heavy and at figure 2 it was too light, the goods would therefore weigh
more than 200 and less than 300 lbs.
Second. Proceed in like manner with the second bar J', which reprc.
sents tens, and it will be found at, say, the figure 3, which will signify.
that the weight is less than 240 but more than 230 lbs.
Third. Proceed in like manner with the third bar J, which repre-
sents units, and the exact weight will be obtained, say 237 lbs. (sec
Figure 10).

page_text: The machine now showing by its indexes E, F, that the exact weight
has been ascertained, the movable stop M is raised so as to prevent move-
ment of the machine. The knob R is then pressed down so as to cause
the block Q to impress on the ticket I the figures representing the
weight. These figures will be found side by side, and can therefore be
casily read.
I may remark that it is always necessary to bring the bars J, J', J,
into the notches L, L, because there would not otherwise be figures
opposite to give the impression of the weight.
This arrangement has over the first arrangement described the advan-
tage that it gives the weight in figures instead of indicating divisions,
which are always liable to cause errors. In short, this arrangement may
be applied to the various forms of weighing machines, and always gives
the same result, viz., a correct weighing, with an indication of the weight
in figures impressed automatically.
The tickets printed by the machines may be made to show on one side
the gross weight, and on the other the tare; also the date and the
number of the machine.
Instead of weights sliding in the usual way on the beam I may use
weights moved in a circular direction at the ends of arms or radii turning
in a vertical plane. On the axis on which these arms turn are keyed
stop ratchets and sectors provided with figures for printing on tickets,
as above explained.
Figures 12, 13, and 14 (Sheet 2) represent another arrangement with
graduated weights. A is the beam formed at the upper side with
notches indicating the weight, while the lower side is furnished opposite
these notches with projecting figures; B is a movable weight sliding on
the beam A; C is a weight for indicating tons, and sliding in the
weight B; it has, like the beam A, notches and projecting figures, but
only from 0 to 9. The weight of C is calculated so as to produce by its
displacement one-tenth of the indications given by the weight B. D is a
weight for indicating units; it has, like C, notches and projecting figures
from 0 to 9; E is a handle to move the weight C; G is an opening in
the weight B for reading off and impressing the weight weighed on the
machine; H is a small movable plate placed at the bottom of the
opening G and below the beam A; J is a cam or excentric on the

page_text: spindle of the handle K; L is the ticket for receiving the impression of
the weight weighed; M is a spring stop on the weight B.
The goods to be weighed having been placed on the platform of the
machine, the weight B is shifted up to the point at which the beam A
indicates equilibrium; then this weight is moved back until the spring
stop M meets one of the notches in the beam A, which makes it
immovable. The same is then done with the weight C for the tens, and
with the weight D for the units. The total weight of the goods is thus
indicated in figures. To obtain an impression of this weight it is
sufficient to put a ticket L in the opening G, then to move the handle K,
which by means of the cam J causes the weight indicated by the pro-
jecting figures to be impressed upon the ticket.
The weight for the units may be dispensed with by using a ticket on
which the units 0 to 9 are printed beforehand. This printing is spaced
according to the distance of the figures representing tens. A small
horizontal line a accompanying cach figure of the tens would indicate
the figure of the units to be taken. One of these printed tickets is
shewn in Figure 15.
2
Figure 16 represents the same ticket after having received the indi-
cation of the weight weighed by a machine with a single sliding weight:
Thus, for example, the weight indicated is 162½ lbs. The figures 1 and
6 have been impressed by the projecting figures on the beam, and
represent the hundreds and tens. The small horizontal line a following
the figure 6 of the tens shows that the unit to be taken is 2 plus a
fraction of about 1, making the total weight 162 lbs.
Figure 17 represents a ticket which has been used in a machine with
two sliding weights capable of weighing up to 2,000 lbs. The weight
indicated is 1,870 lbs.
Lastly. Figure 18 represents a ticket from a machine with one sliding
weight and two bolts (verrous). The weight impressed is 19,756 lbs.
It is formed by the figures 19 of the beam which represent thousands,
then by the figure 7 of the first bolt, which indicates hundreds, then by.
the figure 5 of the second bolt, marking the tens; finally, the figure 6 of
the units is shown by the horizontal line a, making the total 19,756 lbs.
Figures 19 and 20 represent another arrangement of weighing machine
with multiple weights. A is the frame of the machine; C, the beam or.

page_text: arm connected to the part B; N, a knob to print the figures; O, the
ticket. To weigh with this arrangement of machine it is necessary suc-
cessively to place on the racks G, H, J, the weights D, E, F.. These
weights represent respectively 100 lbs., 10 lbs., and 1 lb. They have cach
a stop at the centre. The discs K, L, M, bear figures in relief showing
the weight of the goods weighed, and the printing is effected in the
imanner above described.
Instead of small tickets each receiving separately an imprint, as
herein before described, a ribbon or endless band may be used, which
successively moves at will in the interior of the movable weight, so as
to receive at each weighing an imprint of the weight. The series of
weighings can thus from time to time be verified on this endless band,
which it is sufficient to unroll."
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,-
-
First. Constructing weighing machines so that they register the weights
weighed, that is to say, print or impress the weight of the goods on a
ticket or like device, this printing being effected in relief or otherwise,
and in a dry or a wet way, substantially in the manner and for the purpose
hercin-before described.
Second. The arrangement of machine with single movable weight;
herein-before described with reference to Figures 1 to 5.
Third. The arrangement of machine with several weights, herein-
before described with reference to Figures 6 to 10.
Fourth. The employment in the movable weight of the machine of a
steel plate for printing lines to indicate units, as herein-before described
with reference to Figure 11.
Fifth. The arrangement of machine with graduated weights, herein-
before described with reference to Figures 12 to 14.
Sixth. The arrangement of machine with multiple weights, herein-
before described with reference to Figures 19 and 20.
Seventh. Constructing weighing machines of my system without the
movable weight for the units, so as to allow of the use of tickets pre-
viously printed with the units, as herein-before described with reference
to Figure 15..

page_text: Eighth. Constructing weighing machines of my system so that a
ribbon or endless band may be used in the movable weight in lieu of
separate tickets, as and for the purpose herein-before described. .
In witness whereof, I, the said Edme Augustin Chameroy, have
hereunto set my hand and seal, this Fifteenth day of July, in
the year of our Lord One thousand eight hundred and seventy-
five.

LETTERS PATENT to Edme Augustin Chameroy, of Faubourg St. Martin,
No. 162, Paris, Manufacturer, for the Invention of "AN IMPROVED REGISTERING,
CONTROLLING, AND WEIGHING MACHINE." IMPROVEMENTS IN WEIGHING
MACHINERY.
Sealed the 16th July 1875, and dated the 6th March 1875.
PROVISIONAL SPECIFICATION left by the said Edino Augustin Chameroy at
the Office of the Commissioners of Patents, with his Petition, on the 6th March
1875.
I, EDME AUGUSTIN CHAMEROY of Faubourg St. Martin No. 162, Paris, Manu-
facturer do hereby declare the nature of tho said Invention for "AN IMPROVED
REGISTERING CONTROLLING AND WEIGHING MACHINE" to be as follows:-
The weighing of goods on ordinary balances or weighing machines often gives rise
to errors because the weight has to be read off directly from the beam without any
mark being preserved by which it can be verified; in fact a verification can only be
obtained by weighing a second time. This drawback would be entirely prevented if
at the time of weighing a printed record of the weight, produced mechanically on the
machine itself, could be obtained. And this is the object of my present Invention.
According to one modification of my Invention which I will describe as applied to
platform scales, a flat steel or brass bar is fixed to the under side of the scale beam
and is engraved in relief with figures indicating the weight of the goods. The
movable weight slides on this bar and on the beam and carries below the bar a small
plate on which a ticket or card rests; below the plate is a cam the axis of which is
provided with a handle.
The operation of the machine is as follows. The goods to be weighed having been
placed on the platform the movable weight is shifted on the beam until an index on
the beam is on a level with a fixed index, that is to say, until a true balance has been
obtained. The weight can then be read off in the usual way from the indications on
the beam. Then to obtain a printed indication of the weight, the ticket is slipped
under the engraved bar, the cam is then turned by means of its handle so as to lift
the small plate, and the ticket is thus caused by pressure to receive an impression of
the figures corresponding to the weight. The cam handle is then lowered and the
ticket withdrawn.
When the weighing has been effected the movement of the beam may be prevented
by a hinged]stop.

page_text: The printing of the ticket might also be done by the means generally adopted for
printing railway tickets or in the damp way followed in numbering bills or warrants.
Or in some cases the figures indicating the weight instead of being engraved on the
beam may be arranged on rotating dises representing units, tens and hundreds.
These discs would be fixed at one point to the machine and be operated by the travel
of the sliding weight on the beam. Or the advance of the weight on the beam could
be effected by an endless screw, or a toothed wheel, or a steel band on an axle which
at the same time works the numbering discs of the weight.
For weighbridges with two beams or for balances with two sliding weights the
application of these several modes will be the same; it will suffice for each weight to
have a system of printing; the figures of which would arrange themselves below one
another on the tickets so that they may be readily added.
According to another arrangement I employ several weights-say three, of different
values and fixed on separate and parallel sliding bars. One weight would be say
10 lbs., another 1 lb. and the third th b. On the under side of the bars is a series
of notches say 10 on each bar and on the upper side is a set of projecting figures, one
opposite each notch. These figures represent on each bar the numbers 0, 1, 2, 3, 4,
5, 6, 7, 8, 9. Each bar has a handle by which it can be lifted on the upper side of the
scale beam is a knife edge on which one notch of each bar rests. Above the bars is a
block having an up-and-down movement in a frame, the downward movement being
given by pressing upon a knob and the upward movement by a spring. The weights
with their bars slide on rails or guides on the scale beam.

The action of this controlling weighing machine is as follows:-After having
"tared" the machine the notches of the several bars must be placed on the knife edge
so that the figures O may be opposite and the weight indicated be 0. The machine in
this first position is in equilibrium that is to say, the movable index and fixed index
are exactly opposite each other. If goods to be weighed be then placed on the
platform and it is required to obtain a prinied record the way to proceed is as
follows:-
First, Try if by pushing the first weight of 10 lbs. on the first bar a notch is
found which corresponds approximately to the weight, it being understood that the
figures indicated on this first bar represents 100 lbs. each. Suppose for example that
the bar placed at the figure 3 was too heavy and at figure 2 it was too light the goods
would therefore weigh more than 200 and less than 300 lbs.
Second. Proceed in like manner with the second bar which represents tens and it
will be found at say the figure 3 which will signify that the weight is less than 240 lbs.
but more than 230 lbs.
Third. Proceed in like manner with the third bar which represents units and the
exact weight will be obtained, say 237 lbs.
The machine now shewing by its indexes that the exact weight has been ascertained
the movable stop is raised so as to prevent movement of the machine. The knob
above mentioned is then pressed down so as to cause the block to impress on the
ticket the figures representing the weight. These figures will be found side by side
and can therefore be easily read.
I may remark that it is always necessary to bring the bars into the notches because
there would not otherwise be figures opposite to give the impression of the weight.
I have described the application of my Invention to a platform weighing machine
but no difficulty will be found in adapting it to an ordinary balance or to a weigh-
bridge for heavy loads or to a steel-yard.
The tickets printed by the machines may be made to shew on one side the gross
weight and on the other the tare, also the date and the number of the machine.
Instead of weighis sliding in the usual way on the beam I may use weights moved
in a circular direction at the ends of arms or radii turning in a vertical plane. On the
axis on which these arms turn are keyed stop ratchets and sectors provided with
figures for printing on tickets as above explained.

NOW KNOW YE that 1 the said Edme Augustin Chameroy do hereby declare
the nature of my said Invention, and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement, thereof,
reference being had to the accompanying Drawings that is to say:-
The weighing of goods on ordinary balances or weighing machines often gives rise

To remove this deject it has been proposed, at the time of weighing, to obtain a printed
record of the weight, produced mechanically on the machine itself, could be obtained.
And this is Now the object of my present Invention and of the several arrangements
herein-after described is to obtain a printed record in a simple and efficient manner.
The first arrangement or modifiention of my Invention, which I will describe as
applied to platform scales, is represented in Figures 1 to 4 Figure 1 being an elevation

ment of the platform A. E the movable index on the beam and F the fixed index on
the frame G is a flat steel or brass bar fixed to the under side of the beam Cand
engraved in relief with figures for indicating the weight of the goods. H is the
movable weight which slides on the beam and carries below the bar, a small
impressing plate J on which a ticket or card I (shewn separately in Figure 5. as
carrying marks to indicate the units) rests; below for the purpose of receiving an impress
of the ascertained weight of the goods on the platform. Below the plate J is a cam or
excentric pressing roller K the axis of which is provided with a handle L.
The operation of the machine is as follows. The goods to be weighed having been
placed on the platform A the movable weight H is shifted on the beam Cuntil the
index E is on a level with the fixed index F that is to say until a true balance has
been obtained. The weight can then be read off in the usual way from the indications
on the beam. Then to obtain a printed record of the weight the ticket I is slipped
under the engraved bar G the cam K is then turned by means of its handle L
so as to lift the plate J and the ticket I is thus caused by pressure to receive an
impression of the figures corresponding to the weight. The cam handle L is then
lowered and the ticket I withdrawn.
When the weighing has been effected the movement of the beam may be prevented
by a hinged stop M.
The printing of the ticket might also be done by the means generally adopted for
printing dating railway tickets or in the damp way followed in numbering bills or
warrante. Or in some cases the figures indicating the weight instead of being
engraved on the beam may be arranged on rotating discs representing units tens and
hundreds. These discs would be fixed at one point to the machine and be operated
by the travel of the sliding weight II on the beam C. Or the advance of the weight
on the beam could be effected by an endless screw or a toothed wheel or a steel band
on an axle which at the same time works the numbering dises of the weight.
For weighbridges with two beams the application of these several modes will be the
same; it will suffice for each weight to have a system of printing the figures of
which would arrange themselves below one another on the ticket so that they may be
readily added.
Again, there could be arranged in the interior of the movable weight H and on the
same plane as the beam Ca steel plate having the units 0 to 9 indicated by lines or
marks engraved in relief which would be impressed on the ticket at the same time as
the figures of the beam. In this case the figures representing tens are followed by a
small line a. The ticket impressed in this way is represented in Figure 11. The
Figures 2 and 7 are marked by the beam and indicate by the line a that the Figure 8
should be taken as the unit as shewn by the corresponding line.
Figures 6 to 10 represent another arrangement in which I employ several weights-
say three of different values and fixed on separate and parallel sliding bars. The
same letters of reference apply to parts corresponding to those represented in
Figures 1 to 4. V is the tare of the machine. J, J, J' are the parallel bars provided
with weights. H, is a weight of say 10 lbs. on the bar J. Ha weight of 1 lb. on
the bar and H a weight of th of a pound on the bar J2. On the under side of
the bars is a series of notches LL say ten on each bar and on the upper side is a
set of projecting figures K one opposite each notch L. These figures represent on
each bar the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Each bar has a handle N, N' N'.
by which it can be lifted. On the upper side of the seale beam O is a knife edge I'
on which one notch L of each bar rests. Above the bars is a block Q having an up-
and-down movement in a frame T the downward movement being given by pressing
upon a knob R and the upward movement by a spring S. The weights with their
bars slide on rails or guides on the scale beam.
The action of this controlling weighing machine is as follows: After having
"tared the machine the notches L of the several bars J, J, J², must be placed on

page_text: the knife edge P so that the figures 0 may he opposite and the weight indicated he 0.
The machine in this first position is in equilibrium that is to say the movable index E
and fixed index F are exactly opposite each other. If goods to be weighed be then
placed on the platform and it is required to obtain a printed record, the way to
proceed is as follows:-
First. Try if by pushing the first weight H on the first bar Ja notch L is found
which corresponds approximately to the weight it being understood that the figures
indicated on the first bar represent 100 lbe. each hundreds. Suppose for example
that the bar placed at with the figure 3 in position was too heavy and at with figure 2
in position it was too light the goods would therefore weigh more than 200 and less than
300 lbs.
Second. Proceed The bar J being left with its second notch on the knife edge, then
proceed in like manner with the second bar J' which represents tens and If it will be
found at is adjusted to say the figure 3, which will that may signify that the weight
is less than 240 but more than 230 lbs.
Third Proceed Next proceed in like manner with the third bar J' which represents
units and the exact weight will be obtained say 237 lbs. (see Figure 10.)
The machine now showing by its indexes E, F that the exact weight has been
ascertained the movable stop M is raised so as to prevent movement of the machine.
The knob R is then pressed down so as to cause the block Q to impress on the ticket I
the figures representing the weight. These figures will be found side by side and can
therefore be easily read, as indicated at Fig. 10.
1 may remark that it is always necessary to bring the bars J, J, J' into the
notches L, L because there would not otherwise be figures opposite to give the
impression of the weight.
This arrangement has over the first arrangement described the advantage that it
gives the weight in figures instead of indicating divisions which are always liable to
cause errors of reading. In short this arrangement may be applied to the various
forms of weighing machines and always gives the same result. viza correct
weighing with an indication of the weight in figures impressed automatically.
The tickets printed by the machines may be made to show on one-side the
gross weight and on the other the tare, also the date and the number of the
machine.
Figures 12, 13, and 14 (Sheet 2) represent another arrangement with graduated
weights. A is the beam formed at the upper side with notches indicating the weight
while the lower side is furnished opposite these notches with projecting figures. B is
a movable weight sliding on the beam A. C is a weight for indicating tens and
sliding in the weight B, it has like the beam A notches and projecting figures but
only from 0 to 9. The weight of C is calculated so as to produce by its displacement
one-tenth of the indictations given by the weight B. D is a weight for indicating
units it has like C notches and projecting figures from 0 to 9. E is a handle to move
the weight C. G is an opening in the weight B for reading off and impressing the
weight weighed on the machine. His a small movable plate placed at the bottom of
the opening G and below the beam A. J is a cam or excentric on the spindle of the
handle K. L is the ticket for receiving the impression of the weight weighed M is a
spring stop on the weight B, for entering the notches of the beam A.
The goods to be weighed having been placed on the platform of the machine the
weight B is shifted up to the point at which the beam A indicates equilibrium; then
this weight is moved back until the spring stop M meets one of the notches in the
beam A which makes it immovable. The same is then done with the weight C for the
tens and with the weight D for the units. The total weight of the goods is thus
indicated in figures. To obtain an impression of this weight it is sufficient to put a
ticket L in the opening G then to move the handle K, which by means of the cam or
excentric roller J causes the weight indicated by the projecting figures to be impressed
upon the ticket.
The weight for the units may be dispensed with by using a ticket on which the

page_text: units 0 to 9 are printed beforehand. This printing is spaced according to the distance
of the figures representing tens. A small horizontal line a accompanying each figure
of the tens would indicate the figure of the units to be taken. One of these printed
tickets is shewn in Figure 15.
Figure 16 represents the same ticket after having received the indication of the
weight weighed by a machine with a single sliding weight. Thus for example the
weight indicated is 162 lbs. The figures 1 and 6 have been impressed by the
projecting figures on the beam and represent the hundreds and tens. The small
horizontal line a following the figure 6 of the tens shows that the unit to be taken is
2 plus a fraction of about making the total weight 162 lbs.
Figure 17 represents a ticket which has been used in a machine with two sliding
weights capable of weighing up to 2000 lbs; the weight indicated is 1,876 lbs.
Lastly. Figure 18 represents a ticket from a machine with one sliding hanging and
two sliding weights and two bolts (verrons). The weight impressed is 19756 lbs.
It is formed by the figures 19 of the beam which represent thousands then by the
figure 7 of the first bolt sliding weight which indicates hundreds, then by the figure 5
of the second bolt sliding weight marking the tens, finally the figure 6 of the units is
shown by the horizontal line a making the total 19756 lbs.
Instead of weights sliding in the usual way on the beam 1 may use weights moved
in a circular direction at the ends of arms or radii turning in a vertical plane. On
the axis on which these arms turn are keyed stop ratchets and sectors provided with
figures for printing on tickets as above explained.
Figures 19 and 20 represent another this arrangement of weighing machine with
multiple weights. A is the frame of the machine the beam or arm connected to
through the part rod 13. with the scale or platform and forming one with a sector frame
furnished with segment racks G III mounted loosely on the fulcrum of the beam Care
three pendent weights D E F which have each a stop or paul at their centre to engage
with their respective rack teeth and hold the weights in their adjusted positions.
Connected rigidly to the arms of these weights are type carrying segments K. L M which
stand above the fulcrum of the beam C and more with the weights and the beam N, a knob
to print the figures denoting the weight of the goods. O the ticket to receive the impress
of the type segments. To weigh with this arrangement of machine it is necessary
successively to pluce on adjust to the racks G, H, J the weights D, E, F. These
weights represent respectively 100 lbs. 10 lbs. and 1lb. They have each a stop at
the centre. The dises The type segments K, L, M bear figures in relief for showing
the weight of the goods weighed and the printing is effected in the manner above
described.
Instead of small tickets each receiving separately an imprint as herein before
described a ribbon or endless bund-may be used which successively moves at will in
the interior of the movable weight so as to receive at each weighing an imprint of
the weight. The series of weighings can thus from time to time be verified on this
endless bund which it is suflicient to troll.

the same is to be performed, I declare that I claim
