Improvements in and relating to Numbering Apparatus for use in
the Manufacture of Paper for Bank-notes and the like.
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
his invention to be as follows:-
This invention relates to a method of impressing continuous numbers on paper
pulp or paper during its manufacture in a paper-machine, and to automatic apparatus
therefor.
The principal feature of the apparatus for realizing the aforesaid method of
numbering consists essentially in the movableness of the filigree characters which, in
this particular case, are numbers. Heretofore the filigree characters employed for
producing impressions on paper pulp have always been fixed and therefore invariable
in their reproduction.
The apparatus by means of which the aforesaid method is carried into effect
comprises a series of discs, each of which is provided with the ten numbers
0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The first or units-disc receives its movement from the
machine itself, as will hereinafter he explained. It actuates the tens-disc, and by a
special mechanism causes it to move through one-tenth of its circumference, that is to
say, it effects a change in the number each time when the units-disc has performed a
complete revolution. The tens-dise in its turn, actuates under similar conditions the
hundreds-dise, the latter actuates the thousands-disc, and so on. In short, each disc is
turned through one-tenth of its circumference when the one which drives it has
accomplished a complete revolution, the succession of the numbers therefore takes
place in the order of the decimal numeration.
In the rotation of the apparatus a cam located in the interior of each disc is set in
motion, and, when turning, causes the number which participates in the numbering to
protrude during about one-third of a revolution of the roller. Each of these numbers
or movable filigrees is, in fact, screwed upon the extremity of a rod or driver which,
when it does not receive any movement from the cam, is under the action of a spring
that tends to act in the opposite direction to that of the cam, that is to say to move
back the character.
Our apparatus comprises discs the number of which is determined by the highest
number to be impressed on the paper.
This apparatus is placed in the interior of the dandy-roller, and supported by the
axis of the latter. The revolution of the dandy-roller serves to impart motion to the
numbering apparatus.
The discs have at their circumference the filigree characters 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Provision is made for stamps carrying light frames of wire gauze, upon each of
which either a light or dark filigree character is provided in the ordinary manner.
The same object can also be obtained by providing the said stamps with an india-
rubber pad having a number in relief or in intaglio; or by any of the means which
have heretofore served to impress filagrees on paper. To the aforesaid stamps is im-
parted an intermittent rectilinear movement produced by means of cams which
novement serves for impressing filigree characters on the pulp. Each character may
form one piece with the stamp which has a square tail-piece adopted to slide in an
opening of corresponding form, which is pierced in the crown of the above-mentioned
lisc and prevents the character from turning. A driver which is guided in a groove
.

page_text: formed in the said disc is connected by a screw-threaded extremity with the tail-piece
of the stamp. A plate spring, one end of which is secured to the disc bears against
the driver so as to press it inwardly into the path of the cam.
The latter is traversed by a small square shaft upon one of whose extremities is
keyed a toothed wheel that receives its motion from another toothed wheel placed
concentrically to the main shaft, but not turning with the same.
The movements which take place for carrying the stamps to the relative positions
which they occupy at the moment when the cams operate that is to say at the time
when the characters are impressed on the paper pulp, are determined by the first of
the said discs, which is the units-disc.
A toothed sector receiving its movement from the said small shaft which traverses
it will in every revolution of this shaft cause the units disc to make one-tenth of a
revolution, through the medium of pinions and a toothed wheel.
In its movement the stamps 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, will in their turn be placed
opposite the aforesaid cam which, at a given moment communicates to them the
movement for effecting the impression.
A bridge-piece fixed by screws upon the disc keeps the aforesaid toothed sector and
pinions in place.
Upon the units-disc is secured a cam whereby the engagement of the tens-disc is
determined.
Two small pinions which gear with each other have their axes fixed
upon a plate connected with the eccentric nave of the tens-disc.
One of the said pinions is of sufficient width to gear constantly with the toothed
crown of the tens-disc and in intermittently with the units-disc through the medium
of a tappet and the toothed crown. A turned cylindrical surface stops the movement of
the aforesaid pinion when one of the characters of the tens-disc is displaced through
one-tenth of a revolution. The said tappet determines the engagement of one pinion
with the toothed crown through the medium of the other pinion.
When the units-disc has effected a complete revolution this mechanism has been set
in motion once, and every character of the tens-disc is thus displaced through one-
tenth of a revolution. If the hundreds-disc is actuated in the same manner, it will
effect one-tenth of a revolution in a complete revolution of the tens-disc that is to say
all the characters will be presented for the impression in a definite order which is that
of the decimal numeration.
When using a numbering apparatus with the paper machine, the dandy roller may
be in its usual place and the said apparatus is located in the interior of the dandy
'roller. In practice this roller is simply placed upon two supports, and bears freely
upon the apron of the machine, so that in its motion of translation this apron will turn
the roller. The dandy roller containing the numbering apparatus can turn under the
same conditions; considering however its weight and the resistances of the entire
mechanism, it may be preferable to actuate the same by a belt so as to maintain a
circumferential velocity equal to that of the apron. In order to obviate the deflection,
the roller can be equilibrated by levers or counterweights, or a roller covered with
india-rubber can be placed below as is done in the case of laid paper or any suitable
arrangements can be adopted.
After the discs required for the highest number which it is proposed to produce in
the paper have been arranged as hereinbefore described the numbering apparatus is
placed in the interior of a dandy roller. Upon the circumference of the latter, and
opposite each of the said discs, is formed an opening in which will appear, for making
impressions in the pulp the series of characters on the movable stamps which are
subjected to the action of the above-mentioned cams. As each stamp is screwed upon
the aforesaid driver it can be adjusted in such a manner that the cam will carry it
just in line or flush with the circumference of the dandy-roller. The cams work
together and are so arranged that their action, which takes place during one-third of
the entire duration of the revolution, will precede by some instants the moment when
the characters must be in contact with the paper under treatment upon the apron and
will discontinue only some instants after. When the characters have been impressed
on the pulp and the stamps are longer subjected to the action of the cam, the operation

page_text: of changing the numbers commences. In the case of the numbers of the units, the
teeth of the above mentioned sector engage with those of a pinion which turns a wheel
through one-tenth of a revolution so as to raise for instance the stamp for the number 1
to the position in which it can be raised by the said cam, this operation being repeated
for all the units.
When the numbers of the tens must be displaced the units-disc is set in motion by
the aforesaid sector some moments after the impression has been made, the tappet
fixed upon this units-disc moves one of the said two pinions which causes the engage-
ment of the other of the two pinions and the toothed part of the units-disc, one-half of
this second pinion gearing constantly with a toothed wheel forming one piece with the
tens-disc. This tens-disc stops at the same time as the units-disc, that is to say
at the end of one tenth of a revolution.
This new position must be occupied by the characters at the moment when the
impression takes place in order that the cam shall be able to operate them A
cylindrical part, against which rubs a plate, which is secured upon the second of the
above-mentioned two pinions, prevents any inopportune movement. The movement
of the numbers of the hundreds, thousands, and so on, is effected in a similar manner,
the hundreds discs being actuated by the tens-disc as herein before described.
When the numbering and counting apparatus is mounted upon the shaft of the
dandy roller, motion is imparted to it by means of the above mentioned small square
shaft which extends through the cams in the marking discs.
This small shaft carries at its extremity a small toothed wheel which receives its
rotary movement from another similar wheel placed upon the main shaft of the
daniy roller. The latter wheel which carries one half of a coupling is loose upon
the main shaft but for imparting rotary motion to the wheel on the said small shaft
it is necessary that it shall not move. The wheel on the small shaft receives its
rotary movement by turning around the one fixed upon the main shaft. These two
wheels are of equal diameter. When the wheel on the small shaft has made a
revolution around the wheel on the main shaft, it has also performed a revolution.
For rendering the wheel on the main shaft immovable it is sufficient to displace a
rod which carries upon its extremity the second half of the above-mentioned coupling
so as to engage the two halves of the latter. The said rod traverses a bracket so
that the second half of the coupling is rendered immovable and also the first balf
when the second half is caused to engage therewith.
In order to cause the engagement always at the place where the disengagement
took place, the two halves of the coupling have each only a single tooth. The tooth
on the part of the coupling which is fixed to the said loose wheel will thus always
encounter the tooth on the second half of the coupling which is held in the bracket
at the same place where it has left it because the bracket is always held in the same
place.
The disengagement can be effected when the numbers are either in the opening or
outside the opening. This enables the same number to be impressed twice or more
times with facility. The time necessary for this purpose is available because the
stamps are kept in their backward position during two-thirds of the revolution of the
roller and will appear in the opening during the other third.
This is obtained by dispensing with the above-mentioned two small pinions, and in
order that it may not be necessary to remove these pinions from the axes on the
round plates upon which they are mounted, which would not be practical, the aforesaid
plates are simply replaced by other plates without pinions.
The said small pinions being thus dispensed with, the discs are firmly connected so
that they can all turn at the same time like a single disc. For this purpose a small
fork piece is secured upon each disc, in the space between two numbers and on the
same line.
As the forked piece for the first disc, engages with that for the second
disc and the latter forked piece with that for the third disc and so on, all the discs
will be connected.
If two, three or more numbering apparatus are fixed upon the same axis in the

page_text: dandy roller, they can be displaced by causing them to slide upon the said axis.
They are stopped by a slide ring provided with a pressing screw.
With regard to the practical realization of the numbering each apparatus has
assigned to it one half of the work to be performed if there are two apparatus, ono
third of the work if there are three apparatus and so on.
Suppose, for example there are 50,000 sheets to be numbered and provision is made
for the use of two numbering apparatus, the first of these is adapted for 1 to 25,000,
and the second apparatus for 25,000 to 50,000 the two apparatus operating at the
samo time.
The movement of the numbering apparatus being in direct relation with that of
the dandy roller in which it is enclosed, because each revolution of the roller corre-
sponds a revolution of the apparatus, the same apparatus can operate with dandy
rollers of different diameters, which is of inportance from an industrial point of
view.
In fact, the sizes of the paper to be numbered can vary somewhat and the indis-
pensible condition of the numbering is that the number shall be formed once in
each sheet and always at the same place. It is therefore necessary that the circum-
ference of the dandy roller shall represent the length of each sheet and consequently
a different dandy roller is required for each different size of paper.
The sizes susceptible of being numbered being three or four, it will be necessary
to have three or four dandy rollers of appropriate diameters, which constitutes a slight
expense, whereas the same numbering apparatus will operate with any of these four
rollers.
Although the operation of the numbering apparatus is made to correspond exactly
with that of the dandy roller, with a view to obtaining a better result, because it is
more certain and convenient, and also with a view to the advantages hereinbefore set
forth, the described apparatus is also adapted to be advantageously operated outside
and independently of the dandy roller either before or after it at any point of the said
apron. In this case the apparatus can be actuated directly. This arrangement may
even present the advantage that by varying the velocity of the apparatus relatively
to that of the paper which is being manufactured, the space between the marks
obtained can be conveniently varied so that in this inanner the changing conditions
depending on the difference in the sizes are fulfilled by the same apparatus.
In the course of the manufacture of paper in a paper-machine it may be necessary,
owing to accidents or other causes to interrupt the numbering while the machine
continues the manufacture.
Various means may be employed for obtaining this result. One of these consists
in simply raising the roller which will stop as soon as it discontinues to bear upon
the apron.
The roller may also be left revolving in its place but the numbering may be
interrupted by causing the stamps for the number at which the apparatus has been
disengaged to make successively any desired number of impressions.
For this purpose it is sufficient to operate the aforesaid coupling so as to discontinue
the motion imparted by the rotation of the roller to the numbering discs and render
these immovable while the roller continues to turn. As this coupling has only one
tooth it permits the re-engagement of its halves at the exact point where the disen-
gagement has been effected. Despite every precaution which may be taken there
will be defective sheets that require to be replaced by others upon which the number
must be impressed separately in order that the series shall be complete. This case
has been provided for in the construction of the improved apparatus, which, when
it is to be used for again impressing certain numbers which are not in consecutive
order, undergoes two modifications that can be rapidly effected.
The first of these modifications consist in connecting all the discs of the same
numbering apparatus with each other so that they will all be displaced at the same
time in each rotation of the entire apparatus. This is obtained by replacing each of
the above-mentioned round plates, which are in the interior of the large toothed

page_text: wheels and which carry the two small pinions, by other plates which, instead of these
small pinions, have each at the same place a piston fixed to them which piston is
adapted to engage with one of the interior teeth on the large discs.
The second modification required consists in securing the movable stamps upon
the circumferences of the discs in the desired order, so that, when properly grouped,
they shall impress the desired numbers by the simultaneous displacement of the
discs. In this manner ten numbers can be impressed at a time in each operation of
the disc.

Improvements in and relating to Numbering Apparatus for use in
the Manufacture of Paper for Bank-notes and the like.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 a method of impressing continuous numbers on paper pulp
or paper during its manufacture in a paper-machine, and to automatic apparatus
therefor.
The principal feature of the apparatus for carrying out the aforesaid method of
numbering consists essentially in the moyableness of the filigree characters which, in
this particular case, are numbers. Heretofore the filigree characters employed for
producing impressions on paper pulp have always been fixed and therefore invariable
in their reproduction. The apparatus by means of which the aforesaid method is
carried into effect comprises a series of discs, each of which is provided with the ten
characters 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The first or units-disc receives its movement
from the machine itself, as will hereinafter be explained. It actuates the tens-disc
and by a special mechanism causes it to move through one-tenth of its circumference,
that is to say, it effects a change in the number each time when the units-disc has
performed a complete revolution. The tens-disc in its turn, actuates under similar
conditions the hundreds dise the latter actuates the thousands disc and so on. In
short each disc is turned through one-tenth of its circumference when the one which
drives it has accomplished a complete revolution, the succession of the numbers
therefore takes place in the order of the decimal numeration.
In the rotation of the apparatus a cam located in the interior of each disc is set in
motion, and, when turning, causes the number which participates in the numbering
to protrude during about one-third of a revolution of the roller. Each of these numbers
or inovable filigrees is in fact, screwed upon the extremity of a rod or driver, which,
when it does not receive any movement from the cam, is under the action of a spring
that tends to act in the opposite direction to that of the cam, that is to say to move
back the character.
The apparatus which I have constructed for carrying the aforesaid method of
numbering into practice is represented by way of example in the accompanying
drawings, in which,
Figure 1 represents the disc for the units and the parts which impart movement to
this first disc.
Figure 2 represents the driving mechanism for moving the discs for the tens.
Figure 3 represents one of the numbering types having filigranes at the moment
when the cam has communicated to it the movement for the impression.
Figure 4 represents a section on the line A-B of the disc for the units and of that
for the tens combined.
Figure 5 represents the apparatus mounted in dandy-roller.

page_text: the
Figure 6 represents the mechanism for moving the apparatus and its adaptation to
paper machine.
Figure 7 represents the support for the dandy cylinder and the numbering
mechanism at the same time.
The apparatus comprises discs C, the number of which is determined by the highest
number to be impressed on the paper. This apparatus is placed in the interior of the
dandy-rollor, and supported by the axis of the latter. The revolution of the dandy
roller serves to impart motion to the numbering apparatus.
The discs C have at their circumference the filigree characters 0, 1, 2, 3, 4, 5, 6,
7, 8, 9. Provision is made for stamps carrying light frames of wire gauze, upon each
of which either a light or dark filigree character is provided in the ordinary manner.
The same object can also be obtained by providing the said stamps with an india-
rubber pad having a number in relief or in intaglio; or by any of the means which
have heretofore served to impress filigrees on paper. To the aforesaid stamps is
imparted an intermittent rectilinear movement produced by means of cams e which
movement serves for impressing filigree characters on the pulp. Each character may
form one piece with this stamp which has a square tail-piece f adapted to slide in an
opening of corresponding form which is pierced in the crown of the above-mentioned
disc C and prevents the character from turning. A driver which is guided in a
groove formed in the said dise is connected by a screw-threaded extremity i with
the tail-piece f of the stamp. A plate spring 9 one end of which is secured to the
disc C bears against the driver so as to press it inwardly into the path of the
cam c.
The latter is traversed by a small square shaft B upon one of whose extremities
is keyed a toothed wheel E that receives its motion from another toothed wheel F
placed concentrically to the main shaft A, but not turning with the same.
The movements which take place for carrying the stamps to the relative positions
which they occupy at the moment when the cams operate that is to say at the time
when the characters are impressed on the paper pulp, are determined by the first of
the said discs C, which is the units-disc.
A toothed sector a (Figure 1) receiving its movement from the said small shaft B
which traverses it will in every revolution of this shaft cause the units-disc C to make
one tenth of a revolution, through the medium of pinions 6 and a toothed wheel c.
In its movement the stamps 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 will in their turn be placed
opposite the aforesaid cam e which, at a given moment, communicates to thein the
movement for effecting the impression.
A bridge-piece k fixed by screws upon the disc C keeps the aforesaid toothed sector
and pinions a and b in place.
The disc C for the tens is set in motion by that of the units, and in such a way
that it executes of a revolution, while the latter makes a whole revolution. This move-
ment of the disc of the tens takes place simultaneously with the movement of the disc
for the units i.e. while the latter is performing the last tenth of its revolution viz.-the
space or distance from 9-0 turning in the direction indicated by the arrow Figure 1.
At the moment when the unit disc Centers upon the last tenth of its course a pin
or stop attached to the disc is in contact with a toothed pinion m, which in turn
engages with a pinion n these pinions m and n turn on two axles mounted upon the
plater which is secured in any suitable manner to the shaft A. It will therefore be
understood that the pin or stop 7 will turn the tens disc through the medium of the
pinions m and n. The pinion n is of sufficient size to enable it to engage continuously
with the toothed segment a (Figures 2, 4) of the disc of the tens, and so as to project
into the round hollowed out portion of the units-disc.
When the disc C is performing the last tenth of its revolution, the pin causes the
pinion m to revolve and as a consequence to impart motion to the other pinion n which
engages with the toothed segment p of the units disc C.
The number of teeth with which the toothed segment is provided is such as to cause
the pinion n to perform a complete revolution.
The third disc is that of the hundreds and is actuated by that of the tens in the same

page_text: way as the latter is by the units disc, and the same arrangement obtains for the discs
of the thousands, millions &c.
One of the said pinions n is of sufficient width to gear constantly with the toothed
crown of the tens-dise and intermittently with the units-disc through the medium of
a tappet and the toothed crown. A turned cylindrical surface s stops the movement
or the aforesaid pinion n when one of the characters on the tens-disc is displaced
through one-tenth of a revolution. The said tappet determines the engagement of
one pinion n with the toothed crown through the medium of the other pinion m.
When the units disc has effected a complete revolution this mechanism has heen
set in motion once, and every character of the tens-disc is thus displaced through one-
tenth of a revolution. If the hundreds-disc is actuated in the same manner, it will
effect one-tenth of a revolution in a complete revolution of the tens- lise that is to say
all the characters will be presented for the impression in a definite order which is that
of the decimal numeration.
Figures 5 and 6 show how the numbering apparatus is adapted to the paper machine,
the dandy roller may be in its usual place and the said apparatus is located in the
interior of the dandy roller. In practice this roller is simply placed upon two supports
(Figure 7) and boars freely upon the apron of the machine, so that in its motion of
translation this apron will turn the roller. The dandy roller containing the number-
ing apparatus can turn under the same conditions, considering however its weight and
the resistances of the entire mechanism, it may be preferable to actuate the same by a
belt so as to maintain a circumferential velocity equal to that of the apron. In order
to obviate the deflection, the roller can be equilibrated by levers or counterweights, or a
roller covered with india-rubber can be placed below as is done in the case of laid
paper, or any suitable arrangements can be adopted.
3
Figure represents two counting and marking apparatus mounted upon the dandy
roller.
Figure 7 represents the support for the dandy roller. After the discs required for
the highest number which it is proposed to produce in the paper have been arranged
as herein before described the numbering apparatus is placed in the interior of a dandy
roller (Figure 5). Upon the circumference of the latter, and opposite each of the said
dises, is formed an opening in which will appear for making impressions in the pulp,
the series of characters on the movable stamps which are subjected to the action of the
above-mentioned cams e. As each stamp is screwed upon the aforesaid driver / it can
bo adjusted in such a manner that the cam will carry it just in line or flush with the
circumference of the dandy roller. The cans work together and are so arranged that
their action, which takes place during one-third of the entire duration of the revolution
will precede by some instants the moment when the characters must be in contact with
the paper under treatment upon the apron and will discontinue only some instants after.
When the characters have been impressed on the pulp and the stamps are no longer
subjected to the action of the cam, the operation of changing the numbers com-
mences. In the case of the numbers of the units, the teeth of the above-mentioned
sector a engage with those of a pinion which turns a wheel c through one tenth of a
revolution, so as to raise for instance, the stamp for the number to the position in which
it can be raised by the said came this operation being repeated for all the units.
When the numbers of the tens must be displaced the units-disc is set in motion by
the aforesaid sector a some moments after the impression has been made, the
tappet (Figure 2) fixed upon this units disc moves one of the said two pinions m
which causes the engagement of the other of the two pinions n and the toothed part p
of the units disc, one half of this second pinion n gearing constantly with a toothed
wheel forming one piece with the tens-dise C. This tens disc stops at the
same time as the units-disc that is to say at the end of one-tenth of a revolution:
The point for example passing from the point 0. This new position must be occupied
by the characters at the moment when the impression takes place in order that the
cam e shall be able to operate them. A cylindrical part, against which rubs a plate
which is secured upon the second of the above-mentioned two pinions n, prevents any
inopportune movement. The movement of the numbers of the hundreds, thousands,

page_text: and so on, is effected in a similar manner, the hundreds discs C" being actuated by
the tens-disc C₁as hereinbefore described.
the
Figures 5 and 6 represent the numbering and counting apparatus mounted upon
shaft of the dandy roller, motion is imparted to it by means of the above-mentioned
small square shaft B which extends through the cams e in the marking discs.
This small shaft carries at its extremity a small toothed wheel E which receives
its rotary movement from another similar wheel F placed upon the main shaft of
the dandy roller. The latter wheel which carries one half of a coupling is loose
upon the main shaft A and also the first part of the gear wheel which adheres
to it, but for imparting rotary motion to the wheel on the said small shaft it is
necessary that it shall not move. The wheel on the small shaft B receives its
rotary movement by turning around the one fixed upon the main shaft. These
two wheels are of equal diameter. When the wheel E on the small shaft has made a
revolution around the wheel F on the main shaft, it has also performed a revolution
upon itself.
For rendering the wheel on the main shaft imunovable it is sufficient to displace a
rod g which carries upon its extremity the second half L of the above-mentioned
coupling so as to engage the two halves of the latter.
The said rod traverses a bracket so that the second half of the coupling is rendered
immovable and also the first half when the second half is caused to engage
therewith.
In order to cause the engagement always at the place where the disengagement
took place, the two halves of the coupling have each only a single tooth. The
tooth on the part of the coupling which is fixed to the said loose wheel F will
thus always encounter the tooth on the second half of the coupling L which is held
in the bracket at the same place where it has left it because the bracket is always
held in the same place.
The disengagement can be effected when the numbers are either in the opening or
outside the opening. This enables the same number to be impressed two or more
times with facility. The time necessary, for this purpose is available because the
stamps are kept in their backward position during two thirds of the revolution of the
roller and will appear in the opening during the other third.
This is obtained by dispensing with the above-mentioned two small pinions, n and m
and in order that it may not be necessary to remove these pinions from the axes on
the round plates upon which they are mounted, which would not be practical, the
aforesaid plates are simply replaced by other plates without pinions.
The said small pinions being thus dispensed with, the discs are firmly connected
so that they can all turn at the same time like a single disc. For this purpose a
small forked piece is secured upon each disc, in the space between two numbers and
on the same line. As the forked piece for the first disc, engages with that for the
second disc and the latter forked piece with that for the third disc and so on, all the
dises will be connected.
If two, three or more numbering apparatus are fixed upon the same axis in the
dandy roller, they can be displaced by causing them to slide upon the said axis. They
are stopped by a slide ring provided with a pressing screw.
With regard to the practical realization of the numbering, each apparatus has
assigned to it one half of the work to be performed if there are two apparatus one
third of the work if there are three apparatus and so on.
Suppose for example there are 50,000 sheets to be numbered and provision is made
for the use of two numbering apparatus the first of these is adapted for 1 to 25,000,
and the second apparatus for 25,000 to 50,000 the two apparatus operating at the
same time.
The movement of the numbering apparatus being in direct relation with that of
the dandy roller in which it is enclosed, because to each revolution of the roller
corresponds a revolution of the apparatus, the same apparatus can operate with
dandy rollers of different diameters, which is of importance from an industrial point
of view.

page_text: In fact the sizes of the paper to be numbered can vary somewhat, and the indis-
pensable condition of the numbering is that the number shall be found once in each
sheet and always at the same place. It is therefore necessary that the circumference
of the dandy roller shall represent the length of each sheet and consequently a
different dandy roller is required for each different size of paper.
The sizes susceptible of being numbered being three or four, it will be necessary
to have three or four dandy rollers of appropriate diameters, which constitutes a
slight expense, whereas the same numbering apparatus will operate with any of these
four rollers.
Although the operation of the numbering apparatus is made to correspond exactly
with that of the dandy roller, with a view to obtaining a better result, because it
is more certain and convenient, and also with a view to the advantages hereinbefore
set forth, the described apparatus is also adapted to be advantageously operated
outside and independently of the dandy roller either before or after it at any point
of the said apron. In this case the apparatus can be actuated directly. This
arrangement may even present the advantage that by varying the velocity of the
apparatus relatively to that of the paper which is being manufactured, the space
between the marks obtained can be conveniently varied so that in this manner the
changing conditions depending on the difference in the sizes are fulfilled by the
same apparatus.
In the course of the manufacture of paper in a paper machine it may be necessary,
owing to accidents or other causes to interrupt the numbering while the machine
continues the manufacture. Various means may be employed for obtaining this
result. One of these consists in simply raising the roller which will stop as soon as
it discontinues to bear upon the apron. The roller may also be left revolving in its
place, but the numbering may be interrupted by causing the stamps for the number
at which the apparatus has been disengaged to make successively any desired number
of impressions. For this purpose it is sufficient to operate the aforesaid coupling
Figure 5 so as to discontinue the motion imparted by the rotation of the roller to the
numbering discs and render these immovable while the roller continues to turn. As
this coupling has only one tooth it permits the re-engagement of its halves, at the
exact point where the disengagement has been effected. Despite every precaution
which may be taken there will be defective sheets that require to be replaced by
others upon which the number must be impressed separately in order that the series
shall be complete. This case has been provided for in the construction of the
improved apparatus, which when it is to be used for again impressing certain
numbers which are not in consecutive order undergoes two modifications that can be
rapidly effected.
The first of these modifications consists in connecting all the discs of the same
numbering apparatus with each other so that they will all be displaced at the same
time in each rotation of the entire apparatus. This is obtained by replacing each of
the above-mentioned round plates, which are in the interior of the large toothed
wheels and which carry the two small pinions, by other plates which, instead of these
small pinions, have each at the same place a piston fixed to them which piston is
adapted to engage with one of the interior teeth on the large discs.
The second modification required consists in securing the movable stamps upon the
circumferences of the discs in the desired order, so that when properly grouped, they
shall impress the desired numbers by the simultaneous displacement of the discs. In
this manner ten numbers can be impressed at a time in each operation of the disc.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed as communicated to me by my
foreign correspondents I declare that what I claim is :-
First. The improved method of impressing continuous numbers on paper pulp or
paper during its manufacture.
Second. The employment of movable filigree characters printing automatically in
B

page_text: the paper pulp, the said characters being actuated by means of dises effecting one by
the other the combined movements of the movable numbering types and provided
in the interior with a cam which in its rotation causes the characters which are
to produce the number protrude and to be compressed; this system enabling the
movable characters to print according to the method and the law of the decimal
numeration
Third. The method of fixing the apparatus upon the shaft of the dandy roller.
Fourth. The improved apparatus arranged constructed and operating substantially
as hereinbefore described and represented in the accompanying drawings.
