COMPLETE SPECIFICATION filed by the said John Henry Johnson at the
Office of the Commissioners of Patents on the 13th June 1882.
JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman "IMPROVEMENTS IN OR CONNECTED WITH PRINTING MACHINES OR
APPARATUS" communicated to me from abroad by Edwyn Anthony of Lincolns
Inn Barrister at Law at present residing at Number 20 East 16th Street in the
City of New York United States of America
The object of this Invention is simply the delivery and folding apparatus of
printing presses which print from two rolls and in such a way that both the rolls
are printed on alike and that the same matter is printed on each side of a roll.
Provided the rolls issue printed on in the manner just described, my Invention is
applicable whatever be the nature of the printing, mechanism, Figures 18 and 19
illustrate such types of printing mechanism.
Considering the case of an eight page paper the formes may be placed on the
forme-bearing cylinder or cylinders so that after the webs have been printed on
both sides each will come out printed either as indicated in Figure 1 or in figure 2
(formes on sidewise) or as in Figure 3 or Figure 4 (formes on lengthwise). In the
latter case when it is desired to deliver the papers folded it is better to arrange
the formes so that the webs may come out printed as shewn in Figure 5 or
Figure 6 instead of as in figures 3 and 4-In figures 1 and 3 each portion A B is
repeated twice consecutively and likewise C. D, If the portions are repeated three
four or more times what follows will still obviously apply and it is needless to
illustrate such cases by separate diagrams-Heretofore the two webs have been
cut, folded and delivered separately-By bringing them together as hereinafter
explained the mechanism required is greatly reduced for the above purposes.―

page_text: After each web has been printed continuously on both sides they are run together
bringing either of the two webs on to the top of the other one-When the webs
are cut before printing they must of course be brought together after the cutting
but when they are cut after printing, it is usually more convenient to bring them
together before cutting because then one pair of cutting cylinders will serve to cut
both webs-When it is desired to deliver unfolded then whether the webs come
out as in Figures 1. 2. 3 or 4 the same part of one web is brought on to the same
part of the other. Thus the A B's of the one web must fall on to the A B's of the
other, and the C. D's of the one on to the C. D's of the other.-The two webs thus
brought together may now be treated as one web and delivered in any suitable
way.
When it is required to deliver folded the cases of the formes on sideways and
that of the formes on lengthwise must be considered separately.
For example "Formes on sideways'
"In addition to the transverse cuts the webs
must be cut longtidunally along their central lines in any suitable way-The
dotted lines in the figures indicate where these transverse and longtidudinal cuts
are to be given-These may be made while the webs are together so that one
apparatus will serve the purpose-Either of two plans may be adopted for bringing
them together, I may treat each web separately and bring in any suitable way the
A B's of each web on to the CD's of the same web-Then any A H and the
sheet C. L underneath it forms a complete paper and similarly any G B and KD
underneath it form a complete paper.
Each web will now be travelling as
indicated in figure 7 (corresponding to Figure 1) or as in Figure 8 (corresponding
to Figure 2) The spaces C. D. will be equal to the breadths A B (or greater if the
motion of the sheets has been accelerated-I can therefore by properly fixing the
distance of travel of the two webs make them run in one stream as illustrated in
Figure 9 an interval being between consecutive papers if the motion has been
accelerated The stream thus shown must now be conducted to a folding apparatus
suitable for folding papers reaching it in the form indicated, If preferred the
stream or either side (say A H of Figure 9) may be turned the other side up in
any suitable way before it reaches the folding mechanism. In this case the
stream would reach the folders in the shape indicated by Figure 10 and the folding
mechahism must of course be correspondingly modified.
The other way of bringing the webs together is the following-Let the one web
(call it Number 1) run constantly in the same path-Let the A. B portions of the
other (call it Number 2) run on to the top of the C. D portions of Number 1 and
its C. D portions underneath the A B portions of Number 1-This may be
accomplished by running the C. D portions of Number 2 (we suppose Number 2
web to be running above Number web (beyond the folding apparatus and
returning them underneath web Number 1 or by turning the C. Ď portions out of
their path by a suitable apparatus and bringing them back underneath No 1
The webs will now be in the state shown in Figures 7 or 8 (as the case may be)
and the after treatment will be as before.
In the case of Formes on Lengthwise. The arrangement of the formes being
such as will bring the webs out printed as shewn in figures 5 and 6 the method of
procedure is similar to the preceding case but no longtidunal cutting is required,
The dotted lines indicate where the transverse cuts are to be made-Treating each
web separately the A B's go on to the G H's and the C. D's on to the K. L's The
webs are then travelling as in figure 11. or figure 12. and being run into one
stream become as in Figure 13. Or (similarly to the case previously described of
the formes on sidewise) No 1 web may be run constantly in one path and the A D's
of web No 2 run on to the G L's of No 1 and the G L's of No 2 run underneath the
A D's of No 1 The webs having by either plan been brought into the state
shown in figure 13 they may be either so conducted to the folding apparatus
or the A B's may be first turned the other side up by any suitable mechanism so
that the papers will go to the folding mechanism (of course suitably modified) as
shown in Figure 14.

page_text: Figures 18 and 19 illustrate one of the methods of treatment hereinbefore
mentioned. After printing on both sides each web is conducted by suitable rollers
to the same pair of cutting cylinders C. D (Figure 18) Issuing at L, they need
not again be separated, when the delivery is open but they may go direct to the
delivery apparatus, When they are to be folded then (treating them in one of the
ways herein before explained) the web A will go in one path to the folding
mechanism alternate portions of the other web (B) going with it and alternate
portions being diverted and conducted by suitable rollers and tapes in a path E F
GH N till they rejoin web A underneath the same. Figure 19 illustrates another
printing mechanism and shows in detail arrangements for bringing the webs
together as hereinbefore explained. Each of the forme bearing cylinders K K L
has placed on it a set of 8 formes (each containing one of the eight pages which
make up the paper in question) The rolls are printed on one side by passing
between cylinders G and K and another by passing between cylinders E and Las
the figure indicates. It is obvious that the formes may be arranged on the
cylinders so that the webs shall pass between the cutting cylinders C. D printed on
as shewn in figures 2. 4 or 6, Tapes (as indicated by the dotted line) pass between
C. and D and around the rollers p. p their ends c. c. being run together by suitably
placed skew pulleys-The knife carried by one of the cylinders C. D has small
portions cut away at intervals and the aforesaid tapes are placed so that when the
knife comes around they may run between the said intervals P is a guard which
enters grooves cut for the purpose in the rollers e, e Its object being to prevent
any possibility of either of the rolls getting between e, and e.
Tapes pass around b₁ d₁. b. d₂ e̟, and 6, and also round d, c and y, D. The last
two sets of tapes are fixed so that they may pass between the before mentioned
intervals of the knife-The rollers l. l, m₁. m, touch a circle whose centre lies in
the common tangent of d, d, and the pair of rollers b. b, oscillate in an arc of a
circle whose centre is coincident with that of the circle previously mentioned-
Their oscilliation is timed so that they deliver sleets alternately between L. and
m₁ m, and their oscillation may complete the severance of the web which the knife
has not entirely effected. A set of tapes starts from a pass round ₁r 8 w and y
and thence to a-Their ends a, a must of course be run together but their course
previous to doing so will depend on the folding mechanism (F) which may be of
any suitable kind and placed somewhere in the space ₁r. 8. wy₁.-A set of tapes
starting from 1, passes round r, 8, w and y, and the said tapes are thence returned
by suitably placed rollers to -Tapes also pass round m₁, their ends ff being
ultimately run together their previous course depending on the folding
mechanism A guard is fixed with its ends running into grooves in the rollers m
and t-Its object is to prevent the oncoming web and sheets from coming against
the roller m. whose motion is in the contrary direction-The course of the webs
may now be easily traced-The web A passes between the cylinder D and the
dotted line tapes thence round e,, and along between the tapes f and a--The
web B passes between C. and the dotted line tapes thence between d₁. d. to the
oscillating rollers b₁. b₂ The sheets delivered by the last mentioned rollers between
m. and m, pass along between the tapes f and a above the web A the sheets
delivered between . . pass round r. 8. w then between y₁. Y. and finally between
the tapes and a but underneath the web B.
The completion of the severance of the web A and the folding may now be
done in any suitable way.-When the other method of treatment herein before
mentioned is adopted separate pairs of cutting cylinders will be required for
each web and the rest of the treatment be what has already been described for
that case.
It is clear that when the delivery is unfolded the foregoing methods are applicable
to all papers whatever the number of their pages and that similar methods apply
to papers of a larger number of pages than 8 when the papers are delivered folded-
For example suppose in printing a 12 page paper, the formes are arranged so that
the webs. come out printed as shown in figure 15-Then, treating each web

page_text: separately by any suitable way, the G H's are brought on to the A B's and the
K. L's under the OP's, Each web will then be travelling as shewn in figure 16
A B consisting of two sheets and C. D of one sheet, and similarly O P consisting
of two sheets and M. N of one sheet. Now let No 1 web run constantly in the
same path, and let the A N's of No. 2 web run underneath the C P's of No 1 web
and the C P's of No 2 web run on the A N's of No 1. The webs will then be
running as in Figure 17, As before they may be taken in that state to the folders
or the OP's may be first turned the other way up so as to bring both streams the
same way up.
One way of bringing together two or more sheets of a stream of papers of the
same size and by a slight adjustment to be able to bring together sheets of another
size is the following.
The sheets which may be travelling with any desired interval between successive
sheets enter the mechanism between the rollers D. C. (see figures 20. 21. 22
and 23)
The course and length of the tapes on the roller D depends upon the path of the
sheet before they enter the said rollers such path being immaterial to the mechanism
herein described and being fixed by other considerations.
The ends d d of each tape must of course ultimately run together and be united
to one another thus making them endless. The sheets (of the required number
together) pass out of the mechanism between the rollers A H-The ends c c
of each tape which passes round the roller H must of course be ultimately brought
together and joined-Their path is immaterial to, and depends upon considerations
outside of, the mechanism herein described.
Similarly the ends a a of the tapes which pass round the rollers C. and A must
be ultimately joined their course being independent of the devices herein shown.―
Tapes pass round the rollers B and E only-Tapes also pass round the four
rollers E. F. B. G (figures 20 and 22) or round the five rollers E F B G L
(Figure 21) or the six rollers E. F. B. G. L. R (figure 23) Obviously these tapes
must run on different parts of the rollers B. E. to the parts on which run the tapes
which pass round B and E only. Starting one of these last mentioned tapes at the
roller F it goes around the roller B then round G (and L in figure 21 and LR
Figure 23) thence round E from which it returns to F and its circuit is complete―
This set of tapes will be called "Set L."
The roller D must have its surface cut away at intervals so that loose pulleys
may be placed on it of smaller diameter than D and which must rotate in the
contrary direction to that of D's motion, Round each of them tapes pass their
course being as follows. Starting one at b it passes round K thence round G (and
Lin Figure 21 and L and R in Figure 23) thence round E and finally round a
loose pulley such as has been described-Its ends bb must of course afterwards
be joined but their course before they do BO may be almost anything
whatever and it may be fixed by cousiderations independent of the mechanism
herein described Y is any suitable fixed guide which passes between grooves in the
roller D. Its function is to prevent any tendency of the motion of the oncoming
sheets as they issue from E being checked by the Roller D whose motion is in the
contrary direction.
The number of the tapes last mentioned should be the same as the number in
"Set L" and one of each set should run on one another the sheets passing between
them.
P and Q are guides centred respectively at A and B and they are moved by
suitable mechansim so that at one time they are in the positions shown in
Figures 20 and 22 and at another in those illustrated in Figures 21 and 23.
The rollers G and F must be capable of being fixed in various positions so that
the length of the circuit l, m. n may be varied at pleasure while the length of the
tapes which go around B. G (and L. Figure 21 and LR Figure 23) E and F remains
the same.
If it is desired to lengthen the circuit l. m. n, F is moved nearer to B
and E and G farther away if to shorten it the converse operation must be performed,

page_text: It is better that F instead of being a roller should be a system of independent
pulleys in order that they be capable of taking a position between B and E,
Or the tapes may be returned by means of skew pulleys fixed at g, g. (Figure 22)
which would cause the motion of the tapes to be at an angle to the plane of the
paper-They would then pass over other pulleys and be joined together-The last
pulleys might be capable of adjustment at different distances so that their movement
might compensate the movement of G.
The shape of the circuit l, m, n is immaterial-There may be only one roller such
as G as shown in Figures 20 and 22 or two as shown in figure 21 or three as
shown in Figure 23 or any other number-When more than one roller such as G is
used only one or more of them as preferred may be made adjustable-The rollers G
and F (or equivalent) must be adjusted so that the length of the circuit l. m, n
equals the length of the particular sheet in question (ineasured in the direction of
its motion) plus the interval between successive sheets-Or it may be any multiple
of the aforesaid length-This adjustment of the distance will bring the sheets
exactly one on the other-By varying the said distance the sheets may be made
to partially overlap one another to any extent desired-The sheets enter between
the rollers D and C, and continue to go around and round the circuit l, m, n (thus
bringing any desired number of sheets together) so long as the guides P. Q are in
the positions shown in Figure 21-When the required number have been thus
brought together the guides must take up the positions shown in figures 20 and 22
and the sheet will pass out between the roller A and H-By properly adjusting
the length of the path l, m, n, l, in the way herein before described, it is clear that
sheets of any size may be brought together or each sheet may be brought not on
the one immediately behind it, but on the next but one, or the next after that or
otherwise-It is obvious that in general when the number of the sheets to be
brought together or their breadth (in the direction of the motion) or the interval
between them is changed the periods of the movements of P and Q must also be
changed-Different shaped cams will be needed for effecting the movements-
Devices for sending one portion of a set of travelling sheets in one direction and
another in another are well known, and any other suitable device (for example a
pair of oscillating rollers) may be used instead of the one here specified-The
rollers shown in the drawings need not be equal to one another and they may be
of any convenient diameters.
Having now described and particularly ascertained the nature of the said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention to be secured to me by Letters Patent is.―
First The combining together (after they have printed on both sides so as to
issue in the way herein before specified) of two webs substantially in the manner
and for the purposes herein before described and illustrated in the accompanying
drawings.
Second. The bringing together any number of travelling sheets the mechanism
being capable by adjustment of thus bringing together sheets of any the same size
substantially in the manner and for the purpose herein before described and
illustrated in the drawings.
In witness whereof I the said John Henry Johnson have to this my
Specification set my hand and seal this thirteenth day of June One
thousand eight hundred and eighty two.
