Improvements in Machines for Printing and Associating Webs of
Paper, Severing the same into Sheets, and Collecting the latter
to Form Products of Various Sizes.
I HENRY EDWARD NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of Middlesex, Civil 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 :-
This invention relates to a web printing and sheet delivery mechanism, that is
especially designed to meet the wants of that class of printing establishments where it
is desired to issue newspapers of a size or volume which varies with different issues.
It is the object of the invention to provide a comparatively simple anti compact
machine having but a single printing mechanism, which will be capable of producing
large variety of different sized products and at a high rate of speed; to so organize the
printing and delivering mechanisms, that the half of supplement sheet of a six-page or
ten-page product may be inset; and, in the case of the ten-page product, inset between
the two full sheets which form eight of the ten pages; and to provide for the automatic
stopping of the machine in case of accidents.
a
The invention consists in the means for presenting the supplement web to the
printing mechanism, and in the organization of web associating and sheet collecting
mechanisms, whereby the sheets of the product are associated, to be presented to the
folding mechanism, and in means operated by the web for automatically stopping the
machine in cases of need.
As a full understanding of the invention can only he given by an illustration and a
detailed description of an organized machine embodying the same, all preliminary
description will be omitted, and a full description given, reference being had to the
accompanying drawings, which illustrate several embodiments of the invention.

Referring now particularly to Figures 1, 2, and 4, it is to be understood that F. I
represent respectively the form and impression cylinders of the printing mechanism.
These cylinders are arranged in any suitable relation to each other, preferably in
substantially the relation shown, and are provided with the usual inking mechanisms
represented by the rolls and cylinders E.
The form cylinders are of sufficient length to carry three forms (for convenience
called plates) abreast, and are preferably of sufficient size to receive two plates
circumferentially, making six plates 1, 2, 3, 4, 5, 6 to each cylinder, as indicated.
The impression cylinders I are provided with sets of sheet holding pins a. b,
which extend one third the length of the cylinders, and are located between, the
ends of the blankets, and in the position occupied by the blank spaces between the
plates 5. 6. These pins are so arranged upon the cylinders that the two sets of pin
come together at each revolution of the cylinders.
These pins are operated so as to be protruded and retracted at the proper times, to
take and release the supplement sheets, as will be hereinafter more fully explained.
Located upon the receiving side of the first form and impression cylinder, are a
pair of cutting cylinders A. B, which are of a circumference equal to the longth
of a sheet, and are provided with a cutting blade which is arranged and operates
in the wellknown way, to partially, but not wholly, to sever the web passing between
them. These cylinders may extend the entire width of the machine, as shown, or
may be of a length equal only to one third the width of the machine.
Located between the cutting cylinders and the first impression cylinder, are a
series of accelerated parting tapes 7, which occupy one-third, or about one-third,
the width of the machine, and pass around pulleys 8, located respectively adjacent
to the cutting cylinders and the first impression cylinder. These tapes operate in the
usual and well known manner, to complete the severance of the sheets from the web.
The cutting cylinders A B are driven at one half the surface speed of the printing
cylinders, while the accelerated tapes 7 are driven at a speed equal to the surface
speed of the printing cylinders.
Located adjacent to the impression cylinder, is a delivery cylinder C, which is
provided with a set of impaling pins c, similar to the pins a, b, and which are, or
may be operated in a similar manner. These pins are so arranged that as the
impression cylinder and the cylinder Care revolved, the two sets of pins b. c will come
together at each revolution of the impression cylinder. The operating mechanism
of the pins is so timed that as the pins are thus brought together, the pins will
be retracted to release the sheet held by them, while the pins c will be protruded
to take said sheet and transfer it onto the cylinder C.
It is of course to he understood that grippers may be employed in place of the
pins a, b, c, the grippers being operated in the usual manner, to take and release
the sheets at the proper times, but the pins will usually be preferable.
Extending from the cylinder C is a systein of taping, which operates to convey
the sheets, or aid in conveying the web, as the case may be, to the sheet collecting
Imechanism, and to convey the sheets thence to the folding mechanism, or the delivery
mechanism proper, which is not shown in the present case.
This system of taping consists of five sets of tapes d, e, f, g, h, which are arranged
as follows: The set of tapes d pass around the cylinder C, and thence forward
beneath rolls 9. 10, and thence partially around a cylinder 20, and upward past a
roll 11, and around pulleys 12, returning beneath rolls 13 & 14, and stretching

page_text: pulleys 15. The tapes f. pass around the cylinder 20, and upward with the tapes d
past the roll 11, and around pulleys 16, located adjacent to the pulleys 12, returning
around stretching pulleys 17. The tapes g. h pass around pulleys 18, 19, mounted
upon the same shafts that carry the pulleys 12, 16, and operate to receive the
sheets from the tapes d, f, and convey them to a longitudinal folder or other
suitable folding or delivery mechanism, not shown. The tapes e occupy only one-
third the width of the machine, and pass around the roll 9, and then forward with
the corresponding ones of the tapes d, beneath the roll 10, and around a roll 21,
located near the cylinder 20, returning beneath and above stretching pulleys 22, 23.
Located adjacent to the cylinder 20 is a sheet collecting cylinder 24, which is pro-
vided with a set of impaling pins k. Co-operating with the cylinder 24 is a second
cylinder 25, which is provided with a cutting blade so positioned as to co-operate with
a cutting groove upon the cylinder 24, just in advance of the pins k, to sever the web
as the latter passes between the two cylinders, as will be hereinafter explained.
The cylinder 20 is provided with a set of impaling pins 1, similar to the pins k,
and operated in a similar manner, which act to take the sheets from the cylinder 24
at the proper time, and transfer them to the cylinder 20, and deliver them into the
control of the tapes d f.
l
The pins are operated in such manner that the sheets may be collected upon the
cylinder 24, or be allowed to pass that cylinder without being collected. For this
purpose the operating devices of the pins k are so arranged, that these pins can be
retracted at each revolution of the cylinder, or at each alternate revolution of the
cylinder, while the devices which operate the pins are so arranged that those pins
can be correspondingly protruded. To effect this, the shafts 37 (see Figs. 21 and 22)
upon which the pins k, are mounted, are provided with rock arms 38, having studs
or bowls, which travel in cam grooves 39, formed in the faces of a pair of engaging
gears 40, which are mounted to turn freely upon the shafts of the cylinders 24, 20.
One of the gears 40 is provided, upon its outer face, with a gear 41, which is rigidly
secured to it, and engages with a similar gear 42, mounted to turn upon a stud
projecting from the framework. The gear 42 is fixed to a second gear 43, which
engages with a gear 44, of one half the size of the gear 43, which is fixed upon the
shaft of one of the cylinders. From this it results, that when the gears 12, 43 are in
engagement with the gears 41, 44, the cams 39 are caused to revolve with the
cylinders 20, 24, but at only one half the speed of the cylinders; that is to say,
the cams will make one revolution to two revolutions of the cylinders. The stud upon
which the gears 42, 43 are mounted, is made capable of movement in the frame, as
indicated in figure 21, so that the gears 42, 43, can be thrown out of engagement
with the gears 41, 44, and when this is done, the gears 40 and cams 39 may be
secured in a fixed position in any suitable manner, as by bolts passing through a
bracket 45, and entering the gears. The cams 39 are so formed that when in their
fixed position, they will act to protrude and retract the pins k l at each revolution of
the cylinders 24, 20, and thus prevent the collection of the sheets upon the cylinder 24.
When, however, the cams are operated by the train of gears, they revolve with the
cylinders, but at one half speed, and thus cause the pins k, to be protruded and
retracted only at each alternate revolution of the cylinders, so that the sheets will be
collected by the cylinder 24.
Located between the second impression cylinder and the collecting cylinder 24, is a
web associating mechanism consisting of two parallel turning bars 50, which are
arranged across the path of the web in such position that one of the webs, or one part
of the web, upon being led around the bars, will be transferred laterally a sufficient
distance to be brought over the other part of the web, and in position to be associated
there with, as will more fully appear when the operation of the machine is described.
The framework for supporting the various parts is partially indicated in several
figures of the drawings, but the gearing and connections for transmitting motion to
the various parts have been entirely omitted. Such gearing and connections, however,
constitute no part of the present invention, and being of the ordinary form, can
readily be supplied by any one familiar with the art. Many of the details in the

page_text: construction of the several parts are also omitted, as the different parts are, in them-
selves, common and well known, and a detailed description and illustration of their
construction is therefore unnecessary in order to convey a full understanding of the
invention.
It is also to be remarked that the forin and construction of the several parts can be
considerably modified without departing essentially from the invention, as the
invention relates more particularly to the general organization of the machine and
the manner of combining the several mechanisms, than to the construction of the
individual mechanisms.
The machine thus organized is capacitated to produce the following variety of
products, namely :-
:-
A product consisting of one full sheet.
A product consisting of one full and one half sheet.
A product consisting of two full sheets.
A product consisting of two full sheets and one half sheet; and
A product consisting of two full sheets and two half sheets.
The manner of operating the machine in producing the product consisting of two
full sheets and one half sheet, or what will usually be a ten-page paper, will be first
described. When it is desired to produce this product, the plates will be omitted
from the form cylinders, and the pins a, b, c will be rendered operative. The cutting
cylinders A. B, which, as before stated, are driven at a surface speed equal to one half
the surface speed of the printing cylinders, will be put into operation, and also the
accelerated tapes 7, and the pins will be retracted and the pins / protruded at each
alternate revolution of the cylinders 24 20. A main web K, of two thirds the full
width of the machine, or, in other words, of a width to be perfected by the plates
1, 2, 3, 4 (see Figure 1), will be led directly to the printing mechanism (see Figure 1)
in position to be perfected by these plates. After being perfected, the web K will
pass beneath the roll 9, and upward around a roll 26, and thence around the bars 50,
by which it will be transferred laterally one-half its width, as shown in Figure 5,
after which it will pass around register rolls 27 (see Figure 2), and between the
cutting and collecting cylinders 24, 25, where its leading ond will be taken by the
pins k, and carried around by the cylinder 24. A second or supplement web H (see
Figure 1) of one-half the width of the web K, will be led between the cutting
cylinders A B. (see Figure 2), by which it will be partially severed into sheets, and
will then advance between the accelerated tapes 7 at one half the speed of the web K,
until its leading end arrives in the bite of the pulleys 8, adjacent to the first impression
cylinder, when it will be nipped by the pulleys, and its speed accelerated so as to
complete the severance of the first sheet, and advance its leading end onto the
impression cylinder. The parts will be so timed (see Figure 2), that the leading
end of the sheet will be thus advanced onto the impression cylinder in proper
position to be taken by the pins a, and carried around upon that cylinder, so as to
receive an impression upon one side from the plate 5, carried by the first form
cylinder. The sheet thus held by the pins a, will be carried around upon the first
impression cylinder, until the pins a. come together, when the pins a will be
retracted, and the pins protruded, so that the sheet will be taken by the latter
pins, and transferred onto the second impression cylinder, thus bringing the side
of the sheet already printed next to the second impression cylinder, and the
unprinted side in position to be printed by the form 5. upon the second form
cylinder. The sheet will be carried around upon the second impression cylinder until
the pins b, c come together, when the pins will be retracted, and the pins e protruded,
so as to take the sheet, and transfer it onto the cylinder C, from which cylinder it will
be stripped by the tapes d, and pass into the control of the tapes d. e.
After one sheet has been thus severed from the web H, and accelerated, the end of
the web will continue to advance between the tapes 7 until it passes into the bite of
the pulleys &, when a second sheet will be severed from the web in the same manner,
and at the same this takes place, the pins a will have again arrived in position to
take this second sheet, and so the operation will be repeated. Owing to this acceleration

page_text: of the sheets severed from the web H, each sheet will, as it passes forward between the
tapes d. e, be separated from the following sheet by a space equal to the length of a
sheet (as shown in Figure 2). As the first sheet arrives at the roll 21, it will be
directed around that roll by a switch 28, and its leading end will arrive at the
cylinder 24, in position to be taken by the pins k, and carried around upon that
cylinder imposed upon the leading end of the web K, which latter web has, by reason
of being transferred laterally, been brought into position directly above the path of
the sheets severed from the web H. The leading end of the web K and the sheet
severed from the web H, will be carried around upon the cylinder 24 until the blade
carried by the cylinder 25, co-acting with the groove of the cylinder 24, severs the
web K, just in advance of the pins k, leaving the freshly severed end of the web K
impaled upon the pins, and imposed upon the sheet severed from the web H, the half
sheet being inset between the full sheet and the end of the web, as indicated in
Figure 6.
The two sheets and the leading end of the web thus collected will be carried
around upon the cylinder 24, until the pins k, I come together, when the pins k will
be retracted, and the pins / protruded, so as to take the two sheets and the end of the
web, and transfer them onto the cylinder 20, where they will be carried round upon
said cylinder, until stripped from the pins by the tapes f, when they will pass into the
control of the tapes d, f. When the cutting blade upon the cylinder 25 again comes
into operative position, the second sheet will be severed from the web K, leaving
the freshly severed end of the web impaled upon the pins k, and the operation
will be repeated.
The collected sheets, after leaving the cylinder 20, will pass forward between the
tapes d, f, and be delivered into the control of the tapes g. h, by which they will be
conveyed to a longitudinal folder, or other folding mechanism, and be folded so as
to produce the ten-page product illustrated in Figure 8, the half or supplement sheet
of this product being inset between the main or full sheets.
If it should not be desired to have the half sheets severed from the web H
inset between the full sheets severed from the web K. the switch 28 may be
shifted, as shown in Fig. 2 a, so that the half sheets, instead of being directed around
the roll 21 to the collecting cylinder, will be directed forward beneath the roll 21,
and be associated with the full sheets, as the latter pass into the control of the
tapes d. f.
To produce a product consisting of two full sheets, or what will usually be an
eight page paper, such as shown in Figure 9, the operation will be exactly the same
as just described, except that the web H will be omitted, and in such case, the
pins a, b, c, the cutting cylinders A. B, and accelerated tapes 7, may be rendered
idle. Or instead of operating in this manner, the plates 1, 2 may be omitted, and
the plates 6 supplied, and the web K moved laterally, so as to pass to the printing
cylinders in position to be perfected by the plates 3, 4, 5, 6. In such case, the
pins a, b, c would be rendered idle, and the web, instead of being led upward around
the roll 9, and forward above the roll 26, and around the turning bars, would be
led directly forward between the tapes d, e, and around the roll 21, to the
cylinder 24.
To produce a product consisting of one full sheet, or what will usually be a
four page paper, such as shown in Figure 7, the operation will be exactly the
same as described in connection with the eight-page product, except that the
pins k, l, will be made to operate at each revolution of the cylinders 24, 20, so that
the sheets severed from the web K, instead of being collected, will pass forward
singly between the tapes d f. In this case, of course the plates upon the form
cylinders will be duplicated, so that two papers will be printed at each revolution
of the cylinders.
To produce a product consisting of one full sheet and one half sheet, or what will
usually be a six page paper, such as shown in Figure 12, the form cylinders will each
be provided with six plates, the plates 1, 3, 5 being duplicates of 2, 4, 6.

page_text: The pins
b, c will be rendered inoperative, and the pins k, will remain the same
as in producing the four page paper.
The web H will be led directly to the printing cylinders, as indicated in Figure 3,
or, as will be preferable, a single web equal to the entire width of the machine
will be employed. In either case, the cutting cylinders A. B and the acceleratel
tapes 7 may, of course, be rendered idle. The web or webs, after being perfected,
will pass beneath the roll 9, and if a single wide web is used, it will be acted upon at
that point by a slitter 29, so as to he divided into two webs K H.
The web K will be led around the turning bars, and to the cylinders 24, 25, the
same as first described, while the web H will pass forward between the tapes de, and
to the cylinder 24, as shown in Figure 3, where, owing to the transfer of the web K,
it will become associated with the latter web, and the leading ends of the two webs
will be taken by the pins k, and carried around upon the cylinder 24, until the pins k, l
come together, when the pins will take the leading ends of the webs,- & transfer
them to the cylinder 20, from which they will be taken by the tapes f, & carried
forward between the tapes dj, superimposed, as shewn in Fig. 10. When the cutting
blade of the cylinder 25 comes into position to co-act with the groove of the cylinder 24,
the two webs will be severed, leaving the freshly severed ends of the webs impaled
upon the pins k. The sheets thus severed from the webs will be delivered by the
tapes d, to the tapes g. h, and the full sheet will be folded, thus producing the product
shown in Figure 12.
To produce a product consisting of two full sheets and two half sheets, or what will
usually be a twelve page paper, the operation will be exactly the same as last described,
except that the twelve plates upon the form cylinders will each contain different
matter, and the pins kl will be operated to collect sheets upon the cylinder 24, the
same as in producing the eight and ten page products. The result of this will be,
that the sheets severed from the webs will pass forward between the tapes d, f,
superimposed, as shewn in Fig. 11, and the product, when folded, will be of the form
shewn in Fig. 13.
The organization of the machine which has been described may be varied con-
siderably, without departing from the essential features of the invention. In some
cases, it may be preferred that the web or webs should be led to the printing
mechanism, so that the lower form and impression cylinders will act first upon the
web. If this should be desired, it can readily be accomplished by organizing the
machine, as shewn in Figs. 14 to 18.
This organization is substantially the same as that already described, but it is varied
in some few particulars. In this case, the under set of the accelerated tapes 7 extend
across the entire width of the machine, while the upper set occupy only one
third the width of the machine, as in the organization first described. The
web K is led around the roll 8 at the side of the tapes 7, and is carried forward by
the under set of the tapes 7 to the first impression cylinder, the under set of tapes
thus affording a means of carrying the web, which aids in threading the machine.
The web H, after passing between the cutting cylinders A, B, passes between the
tapes to the first impression cylinder, the same as first described. The tapes d, in
this case, terminate at, and return around the roll 13, which is located adjacent to
the collecting cylinder 24. The tapes e are arranged substantially the same as in
the organization first described. The web K, instead of leaving the last impression
cylinder at the cylinder C, is led from the cylinder around a roll 30, and thence
around guide rolls 31, 32, to the turning bars, where it is transferred laterally, as
shewn in Fig. 17, and thence passes to the rolls 27, the same as in the organization
first described. The cylinder 20 is in this case omitted, and the collecting cylinder 24
is provided with a set of lifting fingers p, which are constructed and operated to
strip the sheets from the pins, and to direct the sheets off the cylinder into the
control of two sets of tapes m n, which pass respectively around pulleys 33, 34,
adjacent to the cylinder, and return around the pulleys 16, 12, and operate to
convey the sheets from the collecting cylinder to the tapes g h.

page_text: The operation of the machine thus organized in producing a ten page product is the
same as in the organization first described, except that the associated sheets, instead of
being taken by the pins of the cylinder 20, and delivered to the tapes df, to be
conveyed to the tapes g h, are directed off the cylinder 24 by the fingers p into the
control of the tapes m, n.
In producing the eight page product, the web H and the plates 6 may be omitted,
and the web K led through the machine in exactly the same way as in producing the
ten page product just described, or the plates 1, 2, may be omitted, and the plates 6
supplied, and the web K moved laterally, so as to be in position to be perfected by
the plates 3, 4, 5, 6. The pins a, b, c, being in this case idle, the web K may be led
either around the cylinder Cand between the tapes de to the cutting and collecting
cylinders 24, 25, or it may be led from the roll 30 around the roll 35, and thence above
the turning bars to the rolls 27, and to the cutting and collecting cylinders; the collecting
cylinder being in either case operated the same as in producing the ten page product.
To produce the four-page product, the web K may be led in either of the ways just
described, the fingers p upon the collecting cylinder being operated so as to direct each
shoot separately off of the cylinder, and into the control of the tapes m, n.
To produce the six page product, the plates will be arranged and the web or webs
led to the printing mechanism, the same as in the organization first described. After
being perfected, the web or webs will be led around the rolls 30, 31, 32, and if a single
wide web is used, it will be split by the slitter 29 as it passes the roll 32. From the
roll 32 the web K will pass around the roll 35 to the rolls 27, while the web H will
pass around the turning bars 50, so as to be transferred laterally into position beneath
the web K, as shown in Fig. 18, and will then pass to the rolls 27, associated with the
web K. From the rolls 27, the associated webs will pass to the cutting and collecting
cylinders, and be severed into sheets and delivered to the tapes m, n, the fingers of
the cylinder 24 being in this case operated at each revolution of the cylinder.
To produce the twelve page product, the operation will be the same as in producing
the six page product, except that the plates upon the printing cylinders will not be
duplicated, and the fingers of the collecting cylinder will be operated only at each
alternate revolution of the cylinder, so that two pairs of sheets will be collected before
they are directed off the cylinder.
The organization shewn in Fig. 19 is substantially the same as that last described,
except that in this case the tapes d, e and the cylinder 25 are omitted, and the collecting
cylinder 24 is located adjacent to the cylinder C. The cylinder C is provided with a
cutting groove located just in advance of the pins c, and the collecting cylinder 24 is
provided with a co-acting blade located just in advance of the pins k. The cylinder
24 is also provided in this case with a coacting cylinder 20, similar to the cylinder 20
in the organization first described, having a set of pins 1, which act to take the sheets
from the collecting cylinder at the proper times, and deliver them to the tapes m, n,
the former of which, in this case, pass around the cylinder 20, to be conveyed to the
tapes g, h, and thence to the delivery mechanism
proper.
The operation of the mechanism, thus organized, in producing the various products,
is exactly the same as described in connection with Figs. 14 to 18, except that the web
or webs, after leaving the roll 27, instead of passing to the collecting cylinder 24, pass
to the cylinder C, and thence between the cylinders C and 24, where it or they is or
are severed into sheets. The operation of the cylinders 24 and 20, in collecting and
disposing of the sheets, and in disposing of the sheets without their being collected, is
exactly the same as in the organization first described.
In the organization shewn in Fig. 20, the cylinder C is omitted, and the collecting
cylinder 24 is located adjacent to the impression cylinder, and in about the position
occupied by the cylinder C in the organization shewn in Fig. 19. The collecting
cylinder, in this case, is equipped the same as in Figs. 1 to 4, and is provided with
the co-operating cutting and delivery cylinders 2, 20, the latter having pins 1, the
same as in said Figures. In this case also the turning bars 50, instead of being
arranged horizontally, as in Fig. 19, are arranged vertically. The operation of this
organization is exactly the same as that shewn in Fig. 19, except that the web or webs

page_text: is or are cut into sheets, as it or they pass between the cylinders 24, 25, the same as
in the organization first described.
If it should be desired to unite the sheets forming the product, the machine may be
provided with suitable pasting apparatus, as s, t, (see Fig. 2), which will be operated
in the usual manner to apply lines of paste to the web K, and the web H or the sheet
severed from that web.
The automatic stop mechanism is to be used in connection with a web printing, or
printing and delivery mechanism, for the purpose of stopping the latter in case of the
breaking of the web, and thus preventing a "choke," which would be liable to damage
the machine.
In many web printing machines, as at present organized and operated, the web passes
through the printing mechanism, and through a great part of the delivery mechanism,
before it is severed into sheets. During its passage through the machine, the web
usually undergoes a considerable amount of manipulation; for example, it may be folded
longitudinally, and then transversely, before being severed into sheets; it may be split
longitudinally, and its sections associated; one or both of the sections of the web, or
the whole web, may be turned at right angles one or more times, or be transferred
laterally by passing over turning bars; two webs coming from different rolls may be
associated; two or more webs or sections of a web may be pasted together; the web
may be turned over between the printing of its opposite sides; or it may be made to
undergo various other manipulations. The particular manipulation to which the
web is subjected varies, of course, with different classes of machines, but in all the
more improved web printing machines, the web necessarily undergoes considerable
manipulation, and is subjected to considerable strain, and owing to the fact that the
more improved machines are operated at a very high rate of speed, there is always
more or less danger that the web will become broken, either from some imperfection in
it, or from some slight imperfection in the operation of the machine, and this, when
it occurs, is liable, unless the machine is at once stopped, to cause the damp paper to
wedge in among the parts of the machine in such a way as to occasion a
"choke,"
which will cause much trouble and delay, and is liable to break or otherwise damage
parts of the machine. It is therefore exceedingly desirable that means should be
provided by which, in case the web breaks during any part of its course through the
machine, the machine will be stopped in time to prevent a choke and its attendant
damage.
To this end I provide the devices which are employed to start and stop the machine,
viz., the belt shifter or other similar device, and the brake with connections by which
they can be operated from some moving part of the machine, and these connections
include a clutch nechanism which is operated by an electro-magnet. The term
connections is therefore used to designate the mechanism which connects the belt
shifter or similar device with some moving part of the machine, and through which
the belt shifter is operated from the machine. This magnet is located in an electric
circuit having a number of branches, which are connected with circuit closers
located in different parts of the machine, and so arranged that so long as the web is
unbroken, the circuit through the magnet will remain open, and the clutch mechanism
will not be operated, but when a break occurs in the web, the circuit through the
magnet will be closed, thereby energizing the magnet, and operating the clutch
mechanism, so as to establish the connection between the machine and the stopping
devices, so as to operate these, and stop the machine in time to prevent a choke and
its attendant trouble and damage.
Referring now particularly to Figs. 23 to 28, it is to be understood that A
represents the side frame of a printing mechanism, B the main driving shaft, C, D
the usual fast and loose pulleys, with which the main shaft is provided, E the brake
pulley, the driving belt, and G the usual forked belt shifter. The belt shifter G is
attached to a head 15, which is arranged to slide freely upon a bar H projecting from
the framework A, and is provided with a handle 10 by which the belt shifter can be
operated. The connections for operating the belt shifter from the machine are, in the
case illustrated, organized as follows: The head 15 is provided with an inwardly

page_text: extending har 20, having a rack 19, which engages with a pinion 21, which is,
mounted to turn freely upon a shaft 40, supported in brackets K, extending from the
side frame A. Secured to the sides of the pinion 21, or made integral therewith, is
a ratchet 22, which is of somewhat larger size than the pinion. The shaft 40 is
provided with a gear 39, which engages with a gear 38, mounted on a stud extending
from the bracket K, and connected to a bevel gear 37, which in turn engages with a
similar gear 36, mounted upon a shaft which is constantly driven from the printing
machine, so as to drive the shaft 40 when the printing mechanism is in operation.
The shaft 40, in addition to the loose pinion 21 and ratchet 22, is provided with a
disc 35, which is fixed to the shaft, and carries a friction band 34, inside of which is
arranged a disc 33 which is loose upon the shaft. The friction band 34 is provided
with an adjusting screw 16, by which it can be tightened onto the disc 33, so as to
cause the latter to turn with the shaft 40 until sufficient resistance is offered to
overcome the friction of the band 34. The disc 33 is provided upon its face with one
or more pawls 9, which are so arranged that when they are permitted to do so, they
engage with the ratchet 22, and thus impart the motion of the shaft 40 and disc 33
to the ratchet and the pinion 21, and thence to the rack 19 and the belt shifter. The
pawls 9 are provided at their ends with recesses 2 (see Fig. 28), which are engaged
by the hooked ends of catches 8,, which are also pivoted upon the face of the disc 33,
in such manner as to normally hold the pawls 9 out of engagement with the
ratchet 22, as shown, in Fig. 25. The catches 8 are provided with tail pieces 7, which
project outward slightly, and between which and the pawls are arranged springs 6,
which perform the double function of holding the catches in engagement with the
recesses 2 in the ends of the pawls, and also of throwing the pawls into engagement
with the ratchet 22, whenever they are released from the catches.
F
Located at one side of the disc 33, is a lever 5, which is pivoted upon a bracket I,
in such position that its lower end normally lies out of the path of the tail pieces 7
of the catches 8, as they are carried around by the disc 33 in its revolution with the
shaft 40. The lever 5 is so positioned, however, that by being rocked slightly on its
pivot, its lower end will be thrown into the path of the tail pieces 7, and thus rock
the catches 8, so as to cause them to release the pawls 9, and allow the latter to
engage with the ratchet 22.
t
t
In order to prevent the lever 5, from being sprung or bent as it is struck by the
tail pieces 7, its lower end is arranged to move along the face of, and be supported
by a projection 4, extending from the bracket L. The upper end of the lever 5 is
provided with a cross head. 12, which forms the armature of an electro magnet 23,
which is so arranged that when energized, it will move the armature 12, and thus
rock the lever 5, so as to carry its lower end into the path of the tail pieces 7 of the
catches 8. This magnet 23 is located in the electric circuit before referred to, which
is provided with circuit closers so arranged that whenever the web breaks at any
point in the printing or delivery mechanism, the circuit will be closed through the
magnet, and the magnet energized as just stated.
f
Referring now to Fig. 29, the manner in which the apparatus is applied to ар
ordinary web printing and delivery mechanism will be explained. Although this
particular form of web printing and delivery mechanism has been selected
for the purpose of illustration, the apparatus is equally applicable to the form of
web printing and delivery mechanism shown in Figs. 1 to 20, or to any other, as
will be readily understood from the following description.
It is to be understood; that in the diagram given, M represents the impression
cylinders, N the form cylinders, and n the inking mechanism for the main printing
machine. O represents the main web, o the slitter by which the main web is divided,
and P the web turners by which the sections of the main web are associated. R
represents the single impression cylinder, S the single form cylinder, and the
inking mechanism of the supplement printing machine. T represents the supplement
web, which is of one half the width of the main web, and V the web turners by
which the supplement web is transferred laterally and turned over after it is printed
on one side so as to be re-presented to the same cylinders, to be printed on its other
"

page_text: side. W represents the longitudinal folder by which the two sections of the main
web and the supplement web, after being associated, are folded longitudinally, and
✗ the cutting and folding cylinders by which the associated and longitudinally folded
webs are severed into sheets, and the sheets folded transversely, preparatory to being
finally delivered from the machines.
Located at suitable points in the paths of the webs through the machine where
the webs are most likely to become broken, are a number of circuit closers a, which
consist of fixed contact points 13, located upon one side of the web, and just out of
contact therewith, and light spring contact points 14, located upon the other side of
the web, and arranged to bear gently upon the web, so that as long as the web is
unbroken, the two contact points of the circuit closers are kept apart, but whenever
the web becomes broken at any point where one of these circuit closers is located, the
two contact points will immediately come together, and thus close the circuit at that
point. These contact points 13, 14 are connected by wires b with a suitable battery c,
and with the electro magnet 23, as indicated in Fig. 29, so that whenever the two
points forming any one of the circuit closers are permitted to come together, a
circuit will be closed through the magnet 23, and it will be energized, and rock the
lever 5 as before explained. The points indicated in the diagram for the location of
the circuit closers a, are purely arbitrary, and have been selected merely for the
purpose of illustration. The circuit closers can be located at any points, and there
can be a greater or less number of them, according to the requirements of any
particular machine to which the apparatus is applied.
Referring now again to Figs. 23 to 28, the operation of the automatic stop
mechanism will be explained. In describing this operation, it will first be assumed
that the printing mechanism is operating in a perfect manner so long as this
continues, the contact points 13, 14 of the various circuit closers a will be kept
separated, and no circuit will be completed through the magnet 23; the pawls 9
will be held out of engagement with the ratchet 22 by the catches 8, and the lever 5
will remain in its normal position, so as not to engage with the tail pieces 7; the
shaft 40 will be driven by the printing mechanism, and the disc 33 and pawls 9 will
be carried idly by it, and the belt shifter G and the parts connected therewith will
remain in the position shown in Figs. 23, 24, and 25. If, at any time, however,
either of the webs should break, the contact points of the one of the circuit closers a,
located at or next in advance of the point where the web breaks, will at once, or
almost immediately afterwards, come together, thereby closing the circuit through
the magnet 23, so as to energize the magnet. The magnet thus energized will,
through its armature 12, rock the lever 5, and throw its lower end into the path of
the tail pieces 7, so that as soon as the first one of these tail pieces arrives opposite
the lever, it will be rocked by the lever, so as to disengage the catch 8, and allow the
pawl 9 of that catch to engage with the ratchet 22, and this will cause the ratchet 22
and pinion 21 to revolve with the shaft 40, and thus, through the rack 19, move the
bar 20, and shift the belt F from the fast pulley C to the loose pulley D, and remove
the power from the machine, as shown in Fig. 26. As soon as the belt F has been
fully shifted onto the loose pulley, the belt shifter will be arrested by its head 15
coming into contact with a pin or other suitable stop 17 projecting from the bar H, as
also shown in Fig. 26. As soon as the belt shifter is thus arrested, it will overcome
the friction between the disc 33 and band 34, and permit the band to move around
the disc, and thus avoid danger of breaking the parts of the apparatus, in case the
printing mechanism should not come to rest by the time the belt has been entirely
shifted onto the loose pulley. As the printing mechanisms to which this invention is
designed to be applied are very heavy, and are run at great speed, the parts
necessarily acquire a great momentum, so that the machine will continue to run for a
considerable time are the belt has been shifted onto the loose pulley, unless
resistance is offered. It is therefore desirable, in order to bring the machine to rest
quickly in case of the breaking of the web, to provide a brake mechanism which
shall be automatically applied at the same time the belt is shifted. For this purpose,
the brake pulley E is provided with a brake shoe 50, which is pivoted to the short

page_text: arm of a lever 49, the long arm of which rests upon the upper edge of the bar 20
of the belt shifter. The bar 20 is so formed that when the belt shifter is in its
normal position, that is to say, when the belt is on the fast pulley C, the long arm of
the lever 49 will be raised so as to hold the shoe 50 out of contact with the brake
pulley, as indicated in Fig. 23. The bar 20 is however provided with an incline 18,
which, as the bar is moved outward to shift the belt onto the loose pulley, permits the
long arm of the lever 49 to drop, so as to lower the shoe 50 onto the pulley E and
the shoe 50, and the fulcrum of the lever 49 are so positioned with relation to each
other and to the pulley E, that as soon as the shoe is applied to the pulley, the further
movement of the pulley tends to increase the pressure of the shoe, and make the
brake more effective.
In order to prevent the battery c from being consumed when the machine is not in
operation, and when, as a consequence, the web is not threaded through the machine,
so as to prevent the contact points of the circuit closers a from coming together, and
also to permit the machine to be operated slowly, as in starting up, it is desirable to
provide means by which the clutch mechanism will only be operated to automatically
stop the machine after the belt has been shifted fully onto the fast pulley, or after the
machine has attained its full speed. For this purpose, the circuit in which the
magnet 23 is located is provided with a circuit breaker d, consisting of two contact
points 27, 28, formed of spring arms, and located in such position that the two points
will be brought together, so as to close the circuit at that point only when the bar 20
is moved inward to its extreme position, as shewn in Figs. 24 and 25, so as to shift
the belt pulley onto the fast pulley. From this it will be seen, that whenever the
belt is on the loose pulley, or not fully on the fast pulley, as will be the case when
the machine is at rest, or is being operated slowly, the circuit through the magnet 23
will be broken, so that the clutch mechanism will not be operated by the lever 5,
and the circuit can only be completed when the belt is fully shifted onto the fast
pulley, so as to operate the machine at full speed.
Whenever the clutch mechanism has been operated to shift the belt and apply the
brake, as has been explained, it is of course necessary, before again starting the
machine, to disengage the pawl 9 from the ratchet 22, and restore it to its normal
position. To effect this, the pin or stop 17 is made removable from the bar H, and
the bar is provided with a second pin or stop 24, located outward from the stop 17,
a distance just equal to the distance between two of the teeth of the ratchet 22.
When, therefore, it is decided to disengage the pawl from the ratchet, it is only
necessary to remove the pin or stop 17, and move the bar 20 and the belt shifter
outward, which can readily be done by grasping the handle 10 against the stop 24.
This will, through the rack 19, revolve the ratchet, a distance equal to the length of
one of its teeth, so as to bring the pawl 9 onto the crown of the tooth in the rear of
one with which it is in engagement, and when it is in this position, it will be caught
by the catch 8, and retained, so that the belt shifter and the bar 20 can then be
moved freely inward. The recesses 2 in the ends of the pawls 9 are inclined, as
best shown in Fig. 28, so that as soon as the catches 8 are fairly entered into the
recesses, the tension of the springs 6 will force them further in, and thus raise the
pawls slightly away from the teeth of the ratchet. It is also necessary, before
commencing to shift the belt back onto the fast pulley, to start the machine, to raise
the shoe 50 away from the pulley E. The incline 18 cannot be depended upon for
this purpose, because it would not act to rock the lever 49 until after the belt had
been shifted a considerable part of the required distance. The bar 20 is therefore
provided, upon its under side, with a stud 26, which, as the bar is moved outward
to shift the belt onto the loose pulley, engages with a pivoted dog 25, depending
from the under side of the lever 49, and rocks said dog to the position shown in
Fig. 26. Whenever, therefore, the bar 20 and belt shifter are moved inward, the
stud 26 engages with the recess formed in the end of the dog 25, and acts to raise
the lever abruptly, so as to raise the shoe 50 from the pulley E. As the bar 20 and
the belt shifter are moved inward to their extreme position, the stud 26 is carried so

page_text: far inward as to pass out of the recess in the end of the dog, and permit the latter to
rock back to its normal position, as shown in Fig. 25.
It is to be understood that the electrical connections which are herein illustrated
as consisting of wires b, may in practice be formed partly by the frame and other
parts of the machine.
Although the automatic stop mechanism is herein shown as applied to a machine in
which the starting and stopping is effected by shifting the driving belt from a loose
to a fast pulley, and vice versa, it can, by changing the form of the connections, be
applied equally well to those machines where the starting and stopping is effected by
tightening and loosening the driving belt, or by operating a friction or other clutch,
and such an application of the stop mechanism is, in a broad sense, within the scope
of the present invention.
