I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention a communication to me
from abroad by Auguste Hippolyte Marinoni and Jules Michaud, both of 96 Rue
d'Assas, Paris, France, Machine Builders, to be as follows:-
This Invention relates to improvements in printing machines generally, parts of
said improvements being more especially applicable to perfecting machines or to
double feed machines arranged to print either on both sides of the sheet or on one
side only.
.'
The improvements as regards perfecting machines consist
1st. In mechanical means for receiving the printed sheets.
2nd. In the employment of separate mechanical receivers for the sheets printed
on one side by each of the cylinders.
3rd. In the employment of special cams for this double machine printing on one
side only.
4th. In the employment of a single feeding place in machines for obtaining either
two different impressions on one side only with two different deliveries, or for
printing on both sides of a single sheet.
5th. In means for readily converting the machine from a perfecting machine to
one producing two impressions on one side only.
The improvements in printing machines generally have for object :-
1st. To improve the inking and ink distribution.
2nd. To enable the form to be slid upon the bed from the end of the machine.
3rd. To ensure the cutting up of the sheets without grooving the rollers and also
allow of the displacement of the cutting disc or discs.
4th. To ensure a regular delivery of the sheets from the machine.
I have, in former patents, described various arrangements of mechanical receivers,
some being single for machines working without set-off sheets, and others being
double, which separate and mechanically receive both the printed and the set-off
sheets.

page_text: Reference is to be had to the accompanying drawings forming part of this
Specification, which show examples of the improvements as applied both to
perfecting machines and to machines printing on one side only with two feeding
places.
for
Figures 1 and 2 show two different forms of machine combined in one,
printing on one side of the sheet with two feeding places, the machine being
symmetrical in arrangement, but it will be understood that both ends of the
machine may be made alike if desired.
The same letters of reference represent similar parts, at both ends of the
machine.

To print single sheets on one side only, the sheets are placed on the feed
board C where they are seized by the fingers of cylinder B¹ and after being
printed by said cylinder and conducted to cylinder B, they pass onto the sheet
delivery roller D₁ whence they are conducted by the tapes E' F' G' to the flyers
or mechanical receivers which deposit them upon the receiving table H*.
When the machine is used for perfecting, the feed board G³ is raised out of the
way into the position shown in dotted lines, the set of tapes E, F is raised to the
position shown in dotted lines in order to afford access to the bed for placing
the form in position and the sets of tapes E', F, G¹ and flyer mechanism are put
out of action all the sheets passing out at the opposite end of the machine.
When the machine is to print two sheets at a time on one side only, the sheets
are placed on two feed boards C¹ C as usual; the sheets on feed board C¹ are fed
to cylinder B¹, are printed by it, pass to the delivery roller D¹ and thence, by the
tapes E F G¹, to the flyers I¹ which deposit them upon the receiving table H¹.
The sheets placed on feed board C₁ are fed to and printed by cylinder B' and
pass thence to the delivery roller D2 and by means of the sets of tapes E' F'* G*
are conducted to the flyers I, by which they are deposited upon the receiving
table H'.
The manner in which the sheets are delivered at the two ends of the machine
and the action of the flyers will be readily understood by the aid of the drawing
figure 1 and the foregoing description, and it now remains to explain how the
sheets are seized and released by each of the cylinders B₁ B³. In arrangements
heretofore employed this object has been effected by placing additional cams on
the cam holder and dispensing with the cams NO by which the double single feed
is obtained.
The same result has also been obtained by fixing the cam holder used for
perfecting and placing a second cam holder on the opposite side, which carried the
cams for gripping and releasing the sheets for the two cylinders.
The following arrangement ensures great precision in the gripping and "lay" of
the sheets.
For this purpose the cam holder is fixed without dismounting any of the cams,
which is a very great advantage, and upon the parts which support the cylinders,
cams R' R' are mounted which serve for both gripping and releasing the sheets of
each cylinder. In this arrangement the opening of the fingers is effected at every

page_text: revolution, but they only close once in every two revolutions when the feed board
is down, that is to say if the fingers open at every revolution, they only seize the
sheets at the desired time. The operation of the fingers at every revolution of the
cylinders may also be utilized for causing each cylinder to seize a sheet at every
revolution so as to obtain with a single feeding place two different impressions, on
one side of the sheet. For this purpose, a single cam R¹, is mounted on the frame
of cylinder B, and by operating the cam holder from which the cams A P are
removed the following result is obtained :—The cam R¹ opens the fingers at every
revolution of cylinder B¹ the feed board C¹, is lowered and a sheet is thus seized at
each revolution. The first sheet is printed by said cylinder B¹ and is conveyed by
the tapes E F¹ G¹ to the flyer I¹ by which it is deposited upon the receiving
table H. The second sheet which is also seized by the fingers of cylinder B' is
transferred to cylinder B by the action of the cams N. O mounted upon the cam
holder whence it passes to the delivery roller D' and is carried by the tapes E' F' G³
to the flyers I and deposited upon the receiving table H. In this manner two
separate impressions on one side only of the sheet may be obtained with a single
feeding place the sheets being delivered at opposite ends of the machine. The
improvements hereinbefore described may be applied either in combination or
separately whether the machine be used for perfecting with a single flyer or
mechanical receiver of any suitable kind either vertical, inclined or horizontal,
or whether the machine be used to print two sheets on one side only with a single
flyer or mechanical receiver disposed either vertically, horizontally or at any angle
or with two flyers disposed in either of these ways, or whether the machine has
but a single feeding place. In this latter case the machine may be arranged for
hand delivery or be provided with flyers.
The improvements in the ink distribution are as follows:-as applied to perfecting
machines, the improvement consists in the employment of two inking tables one
cylindrical and the other flat, whereby the ink upon the flat table over which the
inking rollers pass will be more uniformly distributed.
The distributing cylinder or inking table may be arranged in different ways, one
of which is represented in figures 1 and 2:-a vibrating roller a receives ink from
a ductor or fountain roller e¹ and deposits it upon a distributing cylinder T¹ which
is revolved by a band or in other suitable manner such as by means of a rack M
upon the bed gearing with a toothed wheel R; in either case the table T" is
rotated in opposite directions at a surface speed which is always the same as that
of the flat inking table, thereby permitting the inking roller pl to be in continuous
contact with the cylinder T and also with the flat inking table placed beneath said
inking roller, both in its backward and forward movement.
In this manner a very even distribution of the ink is obtained with the aid of
the distributing rollers placed above the distributing cylinder which distribution
may be still more effectually obtained by imparting an endwise motion to the
distributing cylinder T'. The cylinder T¹ may also receive a continuous circular
motion through gearing mounted on the fountain roller or otherwise.
A
In figure 5 the vibrating roller a receives ink from the fountain roller E and
deposits it upon the distributing cylinder T which receives endwise motion.
vibrating roller p mounted in a rocking lever takes the ink from cylinder T and
descending when the inking table arrives beneath it, deposits the ink which has
been already distributed, upon said table. When the work to be executed does not
require so perfect a distribution of the ink, the distributing cylinder T may be
dispensed with and the ink be taken from the fountain roller and deposited
directly upon the inking table. In this case only one vibrating roller is employed
which is mounted in the other arm X of the rocking lever, the vibrating roller P
being used as a distributor. The employment of a distributing cylinder is thus
rendered optional so that the ink distributing apparatus may work in the ordinary
way if desired. To facilitate the placing of heavy forms in position, the arrange-
ment shown in figures 3 and 4 is employed in which the inking table is made
removable as shown. It is supported at one end by stud pins received in holes

page_text: made in the end of the bed while its opposite end is held by thumb screws f
mounted in a bar c which connects the travelling rails of the bed. The screws f
screw into holes tapped in plates d fixed on the underside of the inking table.
Several of these screws f may be mounted along bar c. To place the forms in
position, the screws fare loosened and the inking table removed, after which the
form placed on a board is introduced in the place of the inking table as shown in
figure 4, the upper edge of said board being on a level with or slightly above that
of the bed; the form can then be pushed into its place with the greatest facility.
I have in a former patent described an apparatus for cutting up the sheets by
means of disc cutters which were capable of adjustment said discs passing between
two tapes placed sufficiently close together to support the sheets and ensure their
severance. This arrangement gives good results so long as the tapes are in tension
but does not ensure a regular cutting action when the tapes become slack.
In order to obviate this objection it is proposed to pass the tapes which hold the
sheets close up to the cutter disc, over a pulley having a groove to receive the disc,
whereby the sheets are pressed against and supported by the pulleys and the sheets
are thus severed with great regularity even though the tapes are not in tension.
This arrangement is shown in figure 6 in which A. is an arm carrying the
grooved pulley, the arm being adjustable upon a rod, so as to allow of its adjust-
ment together with the cutting disc C, for cutting the sheets, either at the centre
or other part; it may also be readily put out of action together with the disc
when the sheets do not require to be severed. Figure 7 shows the arm A and
grooved pulley separately. It is also proposed to make the roller r figure 6
movable so as to render it not only possible to vary the angle which the tape
makes with the delivery roller, but also to advance said roller more or less over the
receiving table according to the strength of the paper whereby the delivery of the
sheets is greatly facilitated.

To print single sheets on one side only, the sheets are placed on the laying on
board C¹ where they are seized by the fingers of cylinder B¹, and after being printed
by said cylinder and conducted to cylinder B* they pass onto the sheet delivery
roller D whence they are conducted by the tapes E, F, G³ to the flyers or
mechanical receivers which deposit them upon the receiving table H.
When the machine is used for perfecting, the laying on board C is raised out
of the way into the position shown in dotted lines, the set of tapes E' F' is
raised to the position shown in dotted lines in order to afford access to the bed
for placing the form in position and the sets of tapes E¹, F¹ 'G' and flyer
mechanism I¹ are put out of action, all the sheets passing out at the opposite end
of the machine.
When the machine is to print two sheets at a time on one side only, the
sheets are placed on two laying on boards C³, C' as usual; the sheets on laying
on board are fed to cylinder B₁, are printed by it, pass to the delivery roller D¹,
and thence, by the tapes E, F, G to the flyers I¹ which deposit them upon the
receiving table H¹.
The sheets placed on laying on-board C are laid on and printed by cylinder B
and pass thence to the delivery roller D2 and by means of the sets of tapes E, F, G³,
are conducted to the flyers I by which they are deposited upon the receiving
table H'.
The manner in which the sheets are delivered at the two ends of the machine
and the action of the mechanical receivers will be readily understood by the aid
of the drawing, Figure 1 and the foregoing description, and it now remains to
explain how the sheets are seized and released by each of the cylinders B¹, B³.
In arrangements heretofore employed, this object has been effected by placing
additional cams on the cam holder and dispensing with the cams N. O. by which
the double laying on for printing on one side only is obtained. The same result
has also been obtained by fixing the cam-holder used for perfecting and placing a
second cam-holder on the opposite side, which carried the cams for gripping and
releasing the sheets for the two cylinders.
The following arrangement ensures great precision in the gripping and "lay" of
the sheets.
4
For this purpose the cam holder is fixed without dismounting any of the cams,
which is a very great advantage, and upon the parts which support the cylinders,
cams R¹, R' are mounted which serve for both gripping and releasing the sheets of
each cylinder. In this arrangement the opening motion of the fingers takes place
at each revolution, but they only take a sheet once for every two revolutions, when 5
the laying on board is lowered, that is to say, although the fingers open and close
at every revolution, they only seize the sheets at the desired time. 'The operation
of the fingers at every revolution of the cylinders may also be utilized for causing
each cylinder to seize a sheet at every revolution, so as to obtain with a single
feeding place, two sheets printed on one side only.
For this purpose a fixed cam R¹ mounted upon the frame of cylinder B¹ is
substituted for cam A, for opening and closing the fingers of cylinder B¹ at every
5

page_text: revolution, the said cam R¹ occupying a fixed position with regard to the roller
which actuates the fingers. The cams N, O, P upon the cam holder W move with
it to and from the cylinders.
The parts being thus arranged, the first sheet laid on feed board C¹ is seized
by the fingers of cylinder B¹ and remains attached to said cylinder, while the roller
operating said fingers passes in front of cam N and on the latter moving away
the printed sheet is released by the fingers by the action of cam R¹ and carried
away by the tapes E, F, G to the flyer I¹ by which it is deposited upon the
receiving table H¹.
The second sheet fed from board C¹ is then seized in its turn by the
fingers of cylinder B' and the cam holder W being now brought close up to the
cylinders, whereby the cams NO are caused to act on the rollers operating the
fingers of cylinders B1, B2, the sheet is passed from cylinder B¹ to cylinder B³ and
printed by the latter, after which the grippers are opened by the action of cam P
owing to the cam holder remaining close up to the cylinders, and the sheet is
delivered by the tapes E, F, G2 to the flyers I and deposited upon the receiving
table H. The cam holder W then immediately moves away from the cylinders.
In this manner two sheets printed on one side only may be obtained, with a single
feeding place, the sheets being delivered at opposite ends of the machine.
The improvements hereinbefore described may be applied either in combination
or separately, whether the machine be used for perfecting, with a single flyer or
mechanical receiver of any suitable kind, either vertical, inclined or horizontal, or
whether the machine be used to print two sheets on one side only with a single
Hyer or mechanical receiver disposed, either vertically, horizontally, or at any angle
or with two flyers disposed in either of these ways, or whether the machine has
but a single feeding place. In this latter case the machine may be arranged for
hand delivery or be provided with mechanical receivers.
The improvements in the ink distribution are as follows:-as applied to perfecting
machines, the improvement consists in the employment of two inking tables one
cylindrical and the other flat, whereby the ink upon the flat table over which the
inking rollers pass will be more uniformly distributed. The distributing cylinder
or inking table may be arranged in different ways, one of which is represented in
figures 1 and 2. A vibrating roller a¹ receives ink from a ductor or fountain roller e¹
and deposits it upon a distributing cylinder T' which is revolved by a band or in
other suitable manner such as by means of a rack M upon the bed gearing with a
toothed wheel R, in either case the table T is rotated in opposite directions at a
surface speed which is always the same as that of the flat inking table, thereby
permitting the inking roller p¹ to be in continuous contact with the cylinder T¹
and also with the flat inking table passing beneath said inking roller both in
its backward and forward movement.
In this manner a very even distribution of the ink is obtained with the aid of
the distributing rollers placed above the distributing cylinder which distribution
may be still more effectually obtained by imparting an end wise motion to the
distributing cylinder T¹. The cylinder T₁ may also receive a continuous circular
motion through gearing mounted on the fountain roller or otherwise.
3.3. 3.3. are two sets of inking rollers which are rotated at a surface speed exactly
equal to that of the bed, by the frictional contact of jockey rollers, 1, 2, which
instead of being merely turned by friction from the inking rollers as usual, receive
a positive motion by endless belts from pulleys mounted upon the same shaft as
wheel R. In this manner the inking rollers receive a regular motion and defects
due to the moving form striking the inking rollers when at rest are avoided.
A jockey roller may be placed above each inker or between two inkers as shown.
In figure 5 the vibrating roller a receives ink from the fountain roller E and
deposits it upon the distributing cylinder T which receives endwise motion.
A vibrating roller p mounted in a rocking lever takes the ink from cylinder T
and descending when the inking table arrives beneath it, deposits the ink which
has been already distributed, upon said table. When the work to be executed does

page_text: '
not require so perfect a distribution of the ink, the distributing cylinder T may
be dispensed with and the ink be taken from the fountain roller and deposited
directly upon the flat inking table.
In this case only one vibrating roller is employed which is mounted in the other
arm X of the rocking lever, the vibrating roller P. being used as a distributor.
The employment of a distributing cylinder is thus rendered optional so that the
ink distributing apparatus may work in the ordinary way if desired.
To facilitate the placing of heavy forms in position, the arrangement shown in
figures 3 and 4. is employed in which the inking table is made removable as shown.
It is supported at one end by stud pins received in holes made in the end of the
bed while its opposite end is held by thumb-screws f mounted in a bar c which
connects the travelling rails of the bed. The screws f. screw into holes tapped in
plates & fixed on the underside of the inking table. Several of these screws f may
be mounted along bar c. To place the form in position, the screws fare loosened
and the inking table removed, after which the form placed on a board is introduced
in the place of the inking table as shewn in figure 4, the upper edge of said board
being on a level with or slightly above that of the bed; the form can then be
pushed into its place with the greatest facility.
I have in a former patent described an apparatus for cutting up the sheets by
means of disc cutters which were capable of adjustment, said dises passing between
two tapes, placed sufficiently close together to support the sheets and ensure their
severance. This arrangement gives good results so long as the tapes are in tension,
but does not ensure a regular cutting action when the tapes become slack.
In order to obviate this objection it is proposed to pass the tapes which hold the
sheets close up to the cutter disc, over a pulley having a groove to receive the disc,
whereby the sheets are pressed against and supported by the pulleys and the sheets
are thus severed with great regularity, even though the tapes are not in tension.
This arrangement is shown in figure 6 in which A is an arm carrying the grooved
pulley, the arm being adjustable upon a rod, so as to allow of its adjustment
together with the cutting disc C, for cutting the sheets, either at the centre or other
part; it may also be readily put out of action together with the disc when the
sheets do not require to be severed. Figure 7 shows the arm A. and grooved
pulley separately. It is also proposed to make the roller r figure 6 movable so as
to render it not only possible to vary the angle which the tape makes with the
delivery roller, but also to advance said roller more or less over the receiving table
according to the strength of the paper whereby the delivery of the sheets is
greatly facilitated.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st. The herein described arrangements whereby sheets, perfected or single
printed by one or both cylinders may be mechanically received upon a perfecting
machine with vertical, horizontal or inclined, flyers substantially as specified.
2nd. Arranging the machine for delivering the sheets by means of mechanical
receivers at one end and for hand delivery at the other end as specified.
3rd. The employment of cams fixed upon the supports of the cylinders for the
double laying on for single printing as described.
4th. The herein described arrangements for double laying on for single printing,
with a single feeding place, the cam which causes the closing of the fingers at
every revolution being mounted either upon the cylinder uprights or otherwise as
specified.
5th. The employment in combination of two inking tables, one cylindrical and
the other flat, whereby the ink is more uniformly distributed as described.
6th. The herein described arrangements whereby a distributing cylinder may be
employed at will in printing machines generally as specified.

page_text: 7th. The herein described arrangement of removable inking table whereby to
enable the forms to be slid into position from the end of the machine.
8th. The herein described arrangement of adjustable cutters, applicable to
printing machines generally for dividing the sheets at variable points as described.
9th. The application of an adjustable roller above the sheet delivery roller, for
the purpose of regulating the position of the latter to suit the kind of paper,
whereby the delivery of the sheets greatly facilitated.
10th. The application of the improvements herein described in combination, both
to perfecting and other printing machines generally.
