A communication from
Engineer. "IMPROVEMENTS IN PRINTING MACHINERY."
abroad by Hippolyte Marinoni, of Paris, in the Republic of France.
This Invention relates principally to that class of printing machines known as
perfecting machines, and cousists partly in improvements on Patent No. 2704,
dated 3rd July 1879, which Patent was taken out by me as a communication
from the said Hippolyte Marinoni.
According to the said Patent the printed sheet can, if required, be cut into two
or more parts by a small rotary knife or knives before it comes down on to the
flyer" which delivers it.

The first improvement in this present Invention consists in the use or employ-
ment of one or more flat bars, which stand close and parallel to the delivery tapes..
The result is that when the sheet cut into two or more parts comes down the
delivery tapes, the fresh cut edges are maintained flat in front by the bar or bars,
and this compels the sheet to come down straight on the "flyer." As it is often
compulsory to feed "wastes" in when running up the colour, or for various other
purposes in the process of printing, the "wastes" coming in contact with the knife
or knives would of course be cut, and therefore could not be used again.
remedy this the rotary knife or knives and the flat bar or bars are so connected
together that when feeding "wastes" either of the "layers on can, by means of
a lever or any other suitable mechanical contrivance, suddenly disconnect the knife
or knives, and at the same time lift up the flat bar or bars in front of the "flyer"
completely out of the way, so that the waste sheet is, delivered uncut by the
'flyer." When white sheets are fed in again the bar or bars and the knife or

page_text: knives are at once brought back into working position. Care must be taken when
lifting up the bar or bars that the knife or knives be only disconnected just when
the bar or bars are very nearly out of the stroke of the "flyer," and vice versa
when the bar or bars are lowered, that is, the knife or knives must be first
connected.
Although this improvement is herein before described as applied to perfecting
machines, it is equally applicable to all classes of printing machines in which the
sheet is cut into two or more parts before reaching the "flyer" that delivers it.
The second improvement consists in a new arrangement which allows perfecting
machines to be driven at a higher speed than hitherto. At the present time the
speed is limited on account of the bed lifting slightly at one end when the driving
pinion works down the "shape" at the end of the rack. The result is a shock
which should be avoided. To remedy this, at the four corners of the bed are fitted
adjustable clamp pieces, which work in guides provided in the side frames of the
machine.
In the Specification of the above mentioned Patent, No. 2704, dated 3rd July
1879, an arrangement is described for allowing in perfecting machines working
with set-off sheets the use of double "flyers;" it is now proposed to improve the
arrangement, and this improvement may be advantageous in certain special cases.
Instead of using a half or a portion of the set of tapes, which are therein called set
No. 1, for carrying the sheet under the knife or knives, and the other half, or a
portion of the same set, to carry off the set-off sheet, the whole of that set of tapes
are used to carry off the set-off sheet, and between the tapes No. 1 and the tapes
No. 3, somewhere betwixt the perfecting cylinder and the delivery rollers, a new
set of tapes is introduced, which I will call No. 6, and which carry between them
and the set No. 3 the printed sheet. The advantage of this arrangement is that
the printed sheet may be cut before it reaches the delivery rollers, and that it may
also be possible to do away with the two sets of helping tapes No. 4 and No. 5.
Another advantage is that the printed sheet is brought to the "flyer" for a con-
siderable portion of its travel between two sets of tapes, which are independent of
the cylinders, and this will, therefore, lead to a more perfect delivery of the printed
sheet on the "flyer."
Although the new arrangement of carrying tapes is herein specified as applied to
machines described in the Specification of the said Patent, No. 2704, dated 3rd July
1879, this arrangement is equally applicable to all classes of perfecting machines
working with set-off sheets, and in which two “ flyers," or any similar arrangement,
is employed.
To prevent any drag on any of the tapes it is found advisable to have all the
most important rollers driven direct by connecting them with the main driving
gear of the machine.
This can be effected in various ways, either by an endless
chain passing over all the most important rollers, or still better, by connecting all
these rollers by means of light toothed wheels, which will receive their motion
through bevil wheels and a vertical shaft, which will be worked by means of a pair
of skew wheels, one of which is keyed on the slanting shaft that works the
ink duct.

dated 3rd July 1879, which Patent was taken out by me as a communication from
the said Hippolyte Marinoni.
According to the said Patent the printed sheet can, if required, be cut into two
or more parts by a small rotary knife or knives before it comes down on to the
'flyer" which delivers it.
"
The first improvement in this present Invention consists in the use or employ-
ment of one or more fat bars, which stand close and parallel to the delivery tapes.
The result is that when the sheet cut into two or more parts comes down the
delivery tapes, the fresh cut edges are maintained flat in front by the bar or bars,
and this compels the sheet to come down straight on the "flyer." As it is often
compulsory to feed "wastes" in when running up the colour, or for various other
purposes in the process of printing, the "wastes" coming in contact with the knifo
or knives would of course be cut, and therefore could not be used again. To
remedy this the rotary knife or knives and the flat bar or bars are so connected
together that when feeding "wastes" either of the "layers on can, by means of
a lever, or any other suitable mechanical contrivance, suddenly disconnect the
knife or knives, and at the same time lift up the flat bar or bars in front of the
flyer" completely out of the way, so that the waste sheet is delivered uncut by
the "flyer." When white sheets are fed in again, the bar or bars and the knife or
knives aro at once brought back into working position. Care must be taken when
lifting up the bar or bars that the knife or knives be only disconnected just when
the bar or bars are very nearly out of the stroke of the "flyer," and vice versa

Although this improvement is hereinbefore described as applied to perfecting
machines, it is equally applicable to all classes of printing machines in which the
sheet is cut into two or more parts before reaching the "flyer" that delivers it.
The second improvement consists in a new arrangement which allows perfecting
machines to be driven at a higher speed than hitherto. At the present time the
speed is limited on account of the bed lifting slighly at one end when the driving
pinion works down the "shape "at the end of the rack, and when driving too
fast. The result is a shock which should be avoided. To remedy this, at the four
corners of the bed are fitted adjustable clamp pieces which work in guides provided
in the side frames of the machines.
In the Specification of the above mentioned Patent, No. 2704, dated 3rd July
1879, an arrangement is described for allowing in perfecting machines working
with set-off sheets the use of double "flyers;" it is now proposed to improve the
arrangement, and this improvement may be advantageous in certain special cases.
Instead of using a half or a portion of the set of tapes, which are therein called set
No. 1, for carrying the sheet under the knife or knives, and the other half, or a
portion of the same set, to carry off the set-off sheet, the whole of that set of tapes
are used to carry off the set-off sheet, and between the tapes No. 1 and the tapes
No. 3, somewhere betwixt the perfecting cylinder and the delivery rollers, a new
set of tapes is introduced, which I will call No. 6, and which carry between them
and the set No. 3 the printed sheet. The advantage of this arrangement is that

page_text: the printed sheet may be cut before it reaches the delivery rollers, and that it may
also be possible to do away with the two sets of helping tapes No. 4 and No. 5,
described in Patent No. 2704, dated 3rd July 1879. Another advantage is that
the printed sheet is brought to the "flyer" for a considerable portion of its travel
between two sets of tapes which are independent of the cylinders, and this will
therefore lead to a more perfect delivery of the printed sheet on the "Hyer."
Although the new arrangement of carrying tapes is herein specified as applied
to machines described in the Specification of the said Patent, No. 2704, dated
3rd July 1879, this arrangement is equally applicable to all classes of perfecting
machines working with set-off sheets, and in which two "flyers," or any similar
arrangement; is employed.
To prevent any drag on any of the tapes it is found advisable to have all the
most important rollers driven direct by connecting them with the main driving
gear of the machine. This can be effected in various ways, either by an endless
chain passing over all the most important rollers, or still better, by connecting all
these rollers by means of light toothed wheels, which will receive their motion
through bevil wheels and a vertical shaft, which will be worked by means of a pair
of skew wheels, one of which is keyed on the slanting shaft that works the
ink duct.
But in order that this Invention may be more clearly understood, I will proceed
to describe the same by the aid of the accompanying Sheets of Drawings, in which
Figs. 1 and 2 (Sheet 1) show respectively a side elevation and a plan of the
apparatus comprising the first part of this Invention. A, A, are the flat bars
which stand close and parallel to the delivery tapes for the purpose of compelling
the cut sheet to come down straight on to the "Byer." These bars are mounted
on the shaft F, on one end of which shaft is fixed the crank L, connected by the
rod ML to the screw arrangement, as shown at N (Fig. 1), or to a lever or other
suitable mechanical contrivance, for the purpose of raising or lowering the bars A.
By turning the crank handles on the screwed rod N in one or other direction the
rod M. is moved laterally, and through the crank L causes the shaft F to partially
revolve, and thus raise or lower the said bars. The shaft F is supported at either
end by brackets K. secured to the shaft E. Mounted on the shaft is a lever G
carrying the tappet H, which when the shaft F is partially revolved moves along
the under side of the bracket C mounted loosely on the shaft E, and supporting
one end of the shaft O carrying the knife P. The other end of this shaft is supported
by the bracket 1) also loosely mounted upon the shaft E. When the shaft F is
revolved in the direction to raise the hars A the tappet H acts upon the bracket C
and misos the shaft O, and consequently disconnects the knife P, at the same timo
lifting it clear of the female cutting roller Q. The parts are so arranged that the
tappet H. does not act upon the bracket C until the bars A are clear of the stroke
of the "flyer." When the shaft F is revolved in the direction to cause the bars A
to descend the tappet H no longer acts upon the bracket C, and the shaft O carrying
the knife P is caused to descend by the spring R.
Fig. 3 (Sheet 1) shows a vertical section of one of the adjustable clamp pieces C',
which are fitted to the four corners of the bed B', and which work in guides Gi
provided in the side frames A¹ of the machine for the purpose of preventing the
shock due to the rising of the bed when the driving pinion works down the " shape"
at the end of the rack, or when driving too fast. D' is a bolt and nut for the
purpose of adjusting the clamp piece C¹."
Fig. 4 (Sheet 2) shows the new arrangement of tapes forming the third part of
this Invention. This arrangement is an improvement upon the Patent No. 2704,
dated 3rd July 1879, above referred to, and it consists in employing the whole of
the set of tapes No. 1 for the purpose of carrying off the set-off sheet between
them and set No. 2, and in placing between the sets of tapes No. 1 and No. 3,
somewhere betwixt the perfecting cylinder and the delivery rollers, a new set of
tapes No. 6, which carry between them and the set No. 3 the printed sheet. By

page_text: this arrangement of tapes the sets Nos. 4 and 5 described in the above mentioned
Patent may be dispensed with.
In Fig.4 (Sheet 2) all the most important rollers are driven direct from the main
driving gear of the machine by means of light toothed wheels, which receive their
motion through bevil wheels and a vertical shaft worked by means of a pair of
skew wheels, one of which is keyed on the slanting shaft that works the
ink duct.
In Fig. 5 (Sheet 2) the motion is imparted to the rollers by means of an endless
chain passing over all the most important rollers.
Figs. 6 and 7 (Sheet 3) show the improvements for disconnecting or connecting
the knife or knives as applied to perfecting presses other than those mentioned in
the Patent above referred to.
Having now described the nature of this Invention, and the manner of carrying
the same into effect, I wish it to be understood that what I claim as new is,―
First. The use or employment of one or more flat bars, which stand close and
parallel to the delivery tapes, as and for the purpose herein described.
Second. The arrangement of connecting the rotary knife or knives and the bar
or bars, so that by means of the screwed rod or a lever, or any other suitable
mechanical appliance, the knife or knives may be suddenly disconnected, and at
the same time the bar or bars be lifted up in front of the "flyer" completely out
of the way, as and for the purpose herein described.
Third. The use or employment at the four corners of the bed of adjustable clamp
pieces, which work in guides provided in the side frames of the machine, as and for
the purpose herein described.
Fourth. The arrangement of tapes, as and for the purpose herein described.
In witness whereof, I, the said Albert Sauvée, have hereunto set my hand
and seal, this Twenty-eighth day of May, 1880.
