Improvements in Printing Machines.
I, GEORGE CROYDON MARKS, of 18 Southampton Buildings, Chancery Lane,
London, W.C., Consulting Engineer and Patent Agent (a communication, to me
from The Campbell Printing Press and Manufacturing Company, a Corporation
organized under the laws of the State of New York, of 1 Madison Avenue, City,
County and State of New York, U.S. America, Printing Press Builders) 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:
The aim of this invention is to improve the construction of traveling cylinder
web printing machines, and the improvements are especially applicable to the form
of this machine in which the web is perfected or printed on both sides.
The improvements may be summed under four heads. The first improvement
consists in including the driving mechanism for reciprocating the cylinders
between the side-frames of the machine so that the same is out of the way, whereby
the machine is rendered much more safer and efficient in operation. The second
improvement consists in arranging the loopers that shift the web through the
printing meclianism in position to move substantially parallel to the movement of
the carriers so that the web will pass directly from the feeding-in looper to a
guide moving at one side of the first impression cylinder, and directly from the
guide moving at one side of the second impression cylinder to the feeding-out
Tooper, this arrangement saving a number of bends in the web, and rendering the
feeding action
very easy and direct. The third improvement consists in providing
gearing for positively turning the feeding-out looper so that the web will be
coaxed or combed around the same. The fourth improvement consists in the
special arrangement of the beds, whereby they are arranged horizontally in
different planes, end to end, or one in advance of the other.
A traveling-cylinder, web-perfecting printing machine having these improve-
ments is illustrated in the accompanying three sheets of drawings.
Referring to the drawings and in detail,
Fig. 1 is a side elevation of the machine,
Fig. 2 is a sectional elevation thereof,
Fig. 3 is a detail view upon an enlarged scale of the gearing used to turn the
feeding-out looper, and
Fig. 4 is a cross-sectional view of the driving mechanism.
The specific improvements before referred to can best be understood by a detailed
description of the entire machine.
Referring to the drawings and in detail, 10 and 11 designate the side frames of
the machine, between which are secured the form-beds A and B:

page_text: The form-beds A and B are horizontally arranged, and the form-bed A is arranged
in advance of the bed -B, so that the beds are rendered very accessible for 'the
purpose of placing the forms thereon.

designates the first impression cylinder, and D) the second impression
cylinder.
These impression cylinders are journalled in the movable carriers E E, and have
the usual gears arranged at the ends thereof to mesh with racks secured at the
sides of the beds, as indicated in dotted lines in Fig. 2, so that, as the cylinders
are moved forwards and backwards over the beds, the same will be positively
turned to roll thereover.
Mounted in the movable carriers E E at each side of each impression cylinder
are a number of form inking rollers F F F F, which are arranged to take ink from
the fountains GGG G, which are arranged at each end of each bed, and apply
the same to the forms.
The movable carriers E E are connected together at their rear ends by means of
a tic or brace H.
The movable carriers E E are fitted to slide in ways 12--12 cut or planed into
the side-frames 10 and 11, and the tie or cross-brace H is arranged to work in
slots 13-13 cut in the side-frames 10 and 11.
14 designates the driving shaft, to which power can be applied in any of the
ordinary manners.
On the end of this shaft 14' is arranged a bevel-pinion 15, which meshes with a
large, horizontally-arranged bevel-gear 16; which is mounted on the end of a
shaft 17 journalled in suitable bearings 18 and 19.
The upper bearing 18 has a suitable extending supporting flange 20, which
engages a flange 21 on the bevel-gear 16, so that the bevel-gear 16 is rigidly
journalled and supported.
A wrist-pin 22 is secured in the bevel-gear, and fitting on the same is a square
block 23, which engages a slot or groove 24 formed or planed in the under side of
the brace or tie H.
By this construction, as the bevel-gear 16 is rotated, the movable carriers E E
and the parts mounted therein will be moved forwards and backwards.
This forms a very strong, simple and direct driving mechanism, which is
especially advantageous for use in machines of this character, as being included
entirely between the side-frames, the operators cannot be hurt thereby, and it is
further an advantageous construction in that no pitmen are used, whereby the
reversal in either direction takes place at the same speed and in the same time, so
that the shift of the web in the machine takes place under the same conditions,
when the impression cylinders reverse off the forms in either direction.
The web to be printed is drawn from a web-roll W, which may be arranged in
suitable bearings or brackets extending from the side-frames in the usual manner.
The web is led first around rollers 25 and 26 journalled in the side-frames, then,
around a roller 27, then around a drum 28, which is ternied the feeding-in drum,
then around the feeding-in looper 29, then to a guide or roller 30 journalled in the
carriers EE, then under the impression cylinder C, then over a guide or roller 31
journalled in the carriers E E, then around tlie rollers 32 and 33, then around a
roller or guide 34 journalled' in the carriers E E under the impression cylinder D,
then around a guide or roller 35 journalled in the carriers EE, around the feeding-.
out looper 36, then around a drum 37, which is termed the feeding-out drum.
At this point the web may be severed into sections in the ordinary manner, and
one section of the web led around rollers 38 and 39; and the other section around
suitable turner-bars 41 in the ordinary manner, so that the plicated sections can
be passed over a longitudinal former or folder 40, and the sheets cut therefrom and
delivered and folded in any of the ordinary ways, as desired.
It will be seen that by this passage through the machine, the web will be printed
on opposite sides or perfected.
:
42, 43 and 44 designate a series of tape-pulleys or rollers, around which run a set

page_text: of tapes 45, which coact with the feeding-in drum 28, so that the web will be
positively and evenly pulled from the web-roll W.
+
46 and 47 designate two pulleys, which are driven by any suitable gearing, not
necessary to show.
53 designates adjustable frames, in which frames the roller 32, before referred to,
is journalled.
Also arranged in one of these frames are pulleys 49, 54' and 50, and a pulley 52
is arranged on the same shaft as the roller 32.
A pulley 51 is also arranged on the same shaft as the roller' 33:
A belt 48 is passed around the pulleys 46, 47, 52, 54, 51, 50 and 49, so that the
rollers 32 and 33 will be positively turned in a direction to tend to coax or comb
the web through the machine.
2
By this arrangement, it will also be seen that the roller 32 can be adjusted
without disturbing the tension of the belt 48, this adjustment of the roll 32 being
used to olitain register, that is, to so adjust the length of the web between .the
two impression cylinders, that the impressions printed upon opposite sides will
properly lie back to back.
540, 55 and 56 designate suitable tape-pulleys or rollers, which are mounted in
the frame, and which carry suitable tapes 57 co-acting with the periphery of the
feeding-out drum 37, so that the web will be positively coaxed or combed around
the feeding-out drum.
The feeding-in looper 29 is journalled in suitable arms 59, mounted on a
shaft 60, and these arms have suitable rollers which engage slots cut in cams 61
arranged on the same shaft as the feeding-in drum 28, so that the feeding-in
looper 29 will be vibrated backwards and forwards.
The feeding-out looper 36 is journalled in suitable arms 62 mounted on a
shaft 63, and the arms 62 have rearward extensions 64 in which are journalled
rollers 65, which fit in slots cut in cams 68 arranged upon a shaft 67.
It will be seen that the web passes directly from the feeding-in looper 29 to the
guide-roller 30 mounted in the movable carriers E, and directly from the guide-
roller 35 mounted in the carriers E E to the feeding-out looper 36.
By this arrangement, the pull on the web when the same is shifted is trans-
mitted very directly to the points of resistance, that is, to the periphery of the
impression cylinders, and a number of lends in the web which are necessarily
in the previously designed presses of this character are done away with, and, by
this arrangement, the web can be much easier drawn through the machine.
A gear 68 is arranged on the shaft 67, as indicated in dotted lines in Fig. 3,
and' this gear meshes with a gear 69 loosely journalled on the shaft 63.
An intermediate 70 is mounted upon a suitable stud secured to one of the looper
arms 62, and this intermediate meshes with and turns a pinion 71 mounted on
the shaft of the looper 36.
By this arrangement, the looper 36 will be positively turned to coax or draw
the web forward around the same.
The oscillation of the arms 62 about the shaft 63 as a centre, by means of the
gearing referred to, will cause the pinion 71 to turn in such direction and at such
speed that the web will not slip on the looper 36, as the looper 36 will unroll or
roll up, as it were, in the loop of web around the same, and the gearing before
referred to, besides causing the looper to have this rolling and unrolling motion,
still turns the same continuously so that the web is drawn around the looper
without slip or friction.
This action tends to greatly help the wel through the machine, because it is
at this point that most of the strain of feed comes on the web.
Any suitable gearing may be arranged to drive the various parts of the machine,
one desirable form of spur gearing being indicated in dotted lines in Fig. 1.
The operation of the parts before referred to is as follows:
As the machine is operated, the carriers E E are moved forwards and back-

page_text: wards, and the impression cylinders C and D are thus caused to pass over the
forms placed on the stationary beds A and B.
When the cylinders C and D are pressing the web on to the forms, the looping
roller 29 is caused to move to the left by its cams to take up all the incoming web
paid around the feeding-in .drum 28, and the feeding-out looper 36 is caused to
move to the right to supply the necessary web to the feeding-out drum 37, so that
the web can be continuously paid out from the printing mechanism.
This opposite movement of the feeding-in and feeding-out loopers takes place
at such speed that the web between the loopers will remain stationary during the
said printing operation, so that the cylinders will move through moving folds of
stationarily held web to effect the printing..
As soon as the cylinders pass out of printing contact with the forms, the
looper 29 is caused to move to the right, and the looper 36 to the left.
The movement of the looper 36 to the left, combined with the action of the
feeding-out drum 37, will draw or pull the web that is paid out by the looper 29
and the feeding-in dium 28 forward around the impression cylinders during the
period while the impression cylinders are reversing their direction or travel off of
the forms, so that when the impression cylinders again come into printing contact
with the forms on the return stroke, a fresh portion of web can be presented and
printed by each impression cylinder.
This feeding or shifting action of course takes place as the cylinders reverse off
the forms in either direction, so that the impression cylinders will print on both
their forward and backward strokes.
The improvements herein described are applicable to a traveling cylinder web
press which prints upon but one side of the web, as for example, the bed B and
cylinder D could be considered as omitted, and the web led directly from the
roller 33 to the feeding-out looper 36.
By the arrangements herein described and shown, a machine of this character is
provided which is very rapid and efficient in operation.
The details herein shown and described may be varied by a skilled mechanic
without departing from the scope of the invention, as expressed in the claims.
