PROVISIONAL SPECIFICATION.
Improvements in Rotary Printing Machines.
I, JULES MICHAUD, of 96 Rue d'Assas, Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows:-
:―
In rotary printing machines the counting of the printed sheets, that is to say
the placing same in packets composed of a given number of printed sheets, either
folded or not, is generally effected by a displacement of the sheets delivered, when
the desired number for forming the packet is attained. In previous Patents I have
shown different arrangements designed by me for effecting this result.
The present application for Patent relates to a new method for effecting the
formation of the packets of a given number of the printed sheets and the ready
removal of these packets.
The means I employ consist generally in employing in the machine several tables
or delivery boxes, and of sending to each of these alternately the desired number
of printed sheets, either folded or not. It will be seen that by this method during
the time that the delivery of the sheets is effected on one of the tables or in one
of the boxes, there will be time to remove the packets already received and formed
on the other tables or in the other boxes.
The different arrangements which I employ for effecting this result and which
I hereinafter describe are only given as examples; they may be indefinitely varied,
the following basis being adopted the directing of a given number of sheets first
to one receiving place, then to a second, then to a third, and to a fourth if this is
necessary.
In Sheet 1 Fig. 1 of the accompanying drawings, the sheet 3 after having passed
through the machine and received a certain number of folds, has a last fold
imparted to it between the cylinders 1 and 2. A bar or rod 4 carries a certain
number of blades or deflectors 5, which enter grooves formed in the cylinder 2;
the blades 5 being engaged in this cylinder all the sheets which pass in front of
them, released by the folding blades 6 will become detached from the cylinder, and,
engaging the cords or tapes 7, will be deposited on the table 8. When the table 8
has received the given number of sheets, the blades 5 will be brought to the
position 51, and the sheets will no longer be detached from the cylinder except by
the cords or tapes 9; they pass to the cords or tapes 10 and then fall on to the
table 11. The movement of the blades is obtained by a cam 12, the speed of
rotation of which is determined by the number of sheets to be received, and which
transmits the movement to the blades by the intermediary of levers and connecting
rods 13, 14 and 15.
In Sheet 2 Fig. 2 of the drawings the sheets arrive from the printing machine
at 16; a lever 17 actuated by a cam 18 is alternately brought in front of the set
of tapes 19 and 20 so as to send to one of the receivers 21 or to the other 22 the
number of sheets constituting the packet to be formed.
On Sheet 3 Figs. 3 and 4 of the accompanying drawings the sheet arriving
at 22, then abutting against a stop 23, is arrested at 24; at this moment, the
knife 25 forces the sheet between the rollers 27, 271, and this is received in the
box 28. The same thing occurs with each of the succeeding sheets until the time
when, under the action of the cam 29 and by the intermediary of the levers and
connecting rods 30, 31 and 32, the stop 23 is moved to the position 231; then the

page_text: sheets passing to 24' abut against the fixed stop 33, and are forced by the knife 26
between the rollers 27, 271, and under the action of the pusher 34¹ are delivered
into the box 28' which is adjacent to the box 28.
In Sheet 4 of the accompanying drawings I have represented another arrange-
ment for effecting the same result.
The sheet after having received a last fold from the knife 36, passes between the
rollers 37, 371, and arrives in the receiving box 39, where a pusher or flyer 40 forces
it against a movable stop 41. When the desired number of sheets rest against the
stop 41, those which follow will be applied by the pusher or flyer 40 against the
stop 42 on the other side of the box; for this purpose it is necessary at a given
moment to produce a change of movement in the direction of travel of the pusher
or flyer 40. The mechanism for effecting this is shown in front elevation in Fig. 5
and in plan view in Figure 6. The flyer or pusher 40 is mounted on the shaft 43,
which at its end carries a crank having a slide 44. A circular eccentric 46 making
one revolution for each sheet printed actuates the shaft 43.
A cam 48 acts on a lever 49 carrying an articulated sleeve 50 through which
passes the connecting rod 47 of the eccentric. Under the action of the cam 48,
the sleeve 50 and the connecting rod 47, which it carries with it, occupy two
different positions, and the slide block to which the connecting rod 47 is attached
is brought to one or other of the ends of the crank 44. From the two positions
of the slide block and the eccentric connecting rod the different movements of the
flyer or pusher 40 result, and the consequence of which is that the descending
sheet is struck by it either to the right or to the left.
As this change of position of the connecting rod and of the slide block occurs
under the influence of the cam 48 between the interval of time which separates the
arrival of two sheets: and further as, still by reason of the construction of the
cam 48 and of the speed of the shaft on which it is mounted, the change of direction
of travel of the flyer or pusher 40 occurs at regular periods corresponding to the
impression of the number of sheets to constitute the packet; the result is that a
packet of a given number of sheets will be received on the right hand and then on
the left hand, and that one of them may be removed while the other is in course of
formation as in the arrangements previously described.
In the arrangements described I have only shown two deliveries of sheets, but
it is very evident that I may employ more.

Improvements in Rotary Printing Machines.
I, JULES MICHAUD, of 96 Rue d'Assas, Paris, France, Engineer, 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 :-
In rotary printing machines the counting of the printed sheets, that is to say the
placing same in packets composed of a given number of printed sheets, either
folded or not, is generally effected by a displacement of the sheets delivered, when
the desired number for forming the packet is attained. In previous Patents I have
shown different arrangements designed by me for effecting this result.
The present application for Patent relates to a new method for effecting the
formation of the packets of a given number of printed sheets and the ready removal
of these packets.
The means I employ consist generally in employing in the machine several tables

page_text: or delivery boxes, and of sending to each of these alternately the desired number
of printed sheets either folded or not. It will be seen that by this method during
the time that the delivery of the sheets is effected on one of the tables or in one of
the boxes, there will be time to remove the packets already received and formed
on the other tables or in the other boxes.
The different arrangements which I employ for effecting this result and which I
hereinafter describe, are only given as examples, they may be indefinitely varied, the
following basis being adopted: the directing of a given number of sheets first to
one receiving place, then to a second, then to a third, and to a fourth if this is
necessary.
In Sheet 1 Fig. 1 of the drawings filed with the Provisional Specification the
sheet 3 after having passed through the machine and received a certain number of
folds, has a last fold imparted to it between the cylinders 1 and 2. A bar or rod 4
carries a certain number of blades or deflectors 5, which enter grooves formed in
the cylinder 2; the blades 5 being engaged in this cylinder all the sheets which
pass in front of them released by the folding blades 6, will become detached from
the cylinder, and, engaging the cords or tapes 7, will be deposited on the table 8.
When the table 8 has received the given number of sheets, the blades 5 will be
brought to the position 5¹, and the sheets will no longer be detached from the
cylinder except by the cords or tapes 9; they pass to the cords or tapes 10 and then
fall on to the table 11. The movement of the blades is obtained by a cam 12 the
speed of rotation of which is determined by the number of sheets to be received,
and which transmits the movement to the blades by the intermediary of levers and
connecting rods 13, 14 and 15.
In Sheet 2 Fig. 2.of the drawings the sheets arrive from the printing machine
at 16, a lever 17 actuated by a cam 18 is alternately brought in front of the set of
tapes 19 and 20 so as to send to one of the receivers 21 or to the other 22 the
number of sheets constituting the packet to be formed.
On Sheet 3 Figs. 3 and 4 of the drawings filed with the Provisional Specification
the sheet arriving at 22, then abutting against a stop 23, is arrested at 24; at this
moment the knife 25 forces the sheet between the rollers 27, 271, and this is received
in the box 28. The same thing occurs with each of the succeeding sheets until the
time when, under the action of the cam 29 and by the intermediary of the levers
and connecting rods 30, 31 and 32, the stop 23 is moved to the position 23'; then
the sheets passing to 24¹ abut against the fixed stop 33, and are forced by the
knife 26 between the rollers 27, 27¹, and under the action of the pusher 34¹ are
delivered into the box 28' which is adjacent to the box 28.
The following description of a delivery arrangement for folded sheets which is
shown in Fig. 4 on the sheet of drawings filed with the present Specification is a
modification of that shown in Sheet 3 Figs. 3 and 4 of the drawings filed with the
Provisional Application.
The sheets arrive at 60 between the cords 61 and 62, and a cam 63 through the
intermediary of levers and connecting rods 64 and 65 actuates the stops 66 which,
at exact periods are brought in the passage of the folded sheets and during equal
periods remain raised as is indicated at 66'.
When the stops 66 are raised, the sheets come against the stops 67 fixed to the
flyer 68, and the latter being lowered, places them upon the table at 69.
When the number of sheets at 69 is attained, the stops 66 under the action of
the cam are brought to the lowered position and arrest the following sheets.
The flyer 68 then delivers them on the table at 70 in a position adjacent to
those previously delivered.
While this second packet is being formed the first may be removed.
The second packet being formed, the stops disappear and the following sheets are
delivered again at 69.
In Sheet 4 of the drawings filed with the Provisional Specification I have
represented another arrangement for effecting the same result.
The sheet after having received a last fold from the knife 36, passes between the

page_text: rollers 37, 371 and arrives in the receiving box 39, where a pusher or flyer 40 forces
it against a movable stop 41. When the desired number of sheets rest against
the stop 41, those which follow will be applied by the pusher or flyer 40 against the
stop 42 on the other side of the box; for this purpose it is necessary at a given
moment to produce a change of movement in the direction of travel of the pusher
or flyer 40. The mechanism for effecting this is shown in front elevation in Fig. 5
and in plan view in Fig. 6. The flyer or pusher 40 is mounted on the shaft 43
which at its end carries a crank having a slide 44. A circular eccentric 46 making
one revolution for each sheet printed actuates the shaft 43.
A cam 48 acts on a lever 49 carrying an articulated sleeve 50 through which
passes the connecting rod 47 of the eccentric. Under the action of the cam 48,
the sleeve 50 and the connecting rod 47 which it carries with it occupy two
different positions, and the slide block to which the connecting rod 47 is attached
is brought to one or other of the ends of the crank 44. From the two positions of
the slide block and the eccentric connecting rod the different movements of the
flyer or pusher 40 result, and the consequence of which is that the descending sheet
is struck by it either to the right or to the left.
As this change of position of the connecting rod and of the slido block occurs
under the influence of the cam 48 between the interval of time which separates the
arrival of two sheets; and further as, still by reason of the construction of the
cam. 48 and of the speed of the shaft on which it is mounted, the change of
direction of travel of the flyer or pusher 40 occurs at regular periods corresponding
to the impression of the number of sheets to constitute the packet; the result is
that a packet of a given number of sheets will be received on the right hand and
then on the left, and that one of them may be removed while the other is in course
of formation as in the arrangements previously described.
In the arrangements described I have only shown two deliveries of sheets, but it
is very evident that I may employ more.
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. The combination with a rotary printing machine of parts, blades, movable
levers, etc., for forwarding a given number of sheets in different directions the
ones from the others, the parts being themselves combined with different delivery
receptacles.
2. The combination with a rotary printing machine of movable stops and delivery
receptacles, the function of these stops being for the purpose of arresting the supply
to one or other of the receptacles.
3. The combination with a delivery flyer of movable projections or stops causing
the separation into distinct packets of the sheets received by the flyer.
4. Combination with a rotary printing machine of delivery mechanism the
periodical reversal of the movement of which has the result of sending a given
number of printed sheets in different directions.
