I, JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
gentleman do hereby declare the nature of said Invention for "IMPROVEMENTS
IN PRINTING MACHINES" which Invention has been communicated to me from
abroad by R. Hoe and Company of the City County and State of New York in the
United States of America Printing Machine Manufacturers to be as follows:-
This Invention consists in a modification or extension of the Invention described
in the Specification of Letters Patent N° 2879 A.D. 1882. In the said Specification
it is stated that in order to apply the invention there described the printing
mechanism must be such as to print two webs on both sides each web being
printed on alike, but the matter printed on one side of a web being different from
that printed on the other side And it is further observed that the edges of the
webs must lie in the same pair of parallel planes. The fundamental idea of the
said Invention forming the subject matter of the said patent consists in reversing
one of the webs then bringing the two together (with or without other webs as
therein explained) and longitudinally severing them They are thus caused to form
two streams running side by side, the streams being identical in every way except
that the one is the way up the reverse of the other This conception, however,
admits of a different view. For two such streams are always formed when two
webs printed on as above described are brought together so that a side of one web
is in contact with the similar printed side of the other And by suitable deflection
of the paths of both of the webs (instead of the complete reversal of one of them)
this end may be attained whether the webs issue from the printing mechanism at
an angle to one another or as before described with their edges in the same pair of
parallel planes. This invention consists in carrying out the conception from the
stand point just indicated and the said Invention may be recapitulated as consisting
in combining with a printing press mechanism for printing both sides of two rolls
(each web being printed on alike but with different matter on opposite sides of a
web) with mechanism for deflecting the paths of both webs and mechanism for
longitudinally severing them whereby the similarly printed sides of the two webs
are brought together and they are caused to form two side by-side streams the
saune in every respect except that they are reverse ways up.
Dated this 28th day of August 1885.

I, JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of. Middlesex
Gentleman, do hereby declare the nature of this Invention which has been com-
municated to me from abroad by R. Hoe & Company of the City County and State
of New York in the United States of America Printing Machine Manufacturers
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 an improvement upon that described in Letters Patent
N° 2879 of 1882. In the said Specification it is stated that in order to apply the
Invention the printing mechanism must be such as to print two webs on both
sides each web being printed on alike but the matter printed on one side of a web
being different from that printed on the other; and it is further observed that the
edges of the webs must lie in the same pair of parallel planes. The fundamental
idea of the said patent consists in reversing one of the webs then bringing the two
together (with or without other webs as therein explained) and longitudinally
severing them They are thus caused to form two streams running side by side the
streams being identical in every way except that the one stream is the reverse way
up to what the other stream is This conception however admits of a different
view, for two such streams are always formed when two webs printed on as above
described, are brought together so that a side of one web is in contact with the
similar printed side of the other, and by suitable deflection of the paths of both of
the webs (instead of the complete reversal of one of them) this end may be
attained.
The present invention consists in carrying out the conception from the stand
point just indicated by combining with mechanism for printing both sides of two
webs, means for slitting the same and deflecting mechanism whereby the similarly-
printed sides of the two webs are brought together and form two side by side
streams all of which is more particularly hereinafter set forth and claimed.
Figure 1 is a side elevation and Figure 2 an end view of a machine in accordance
with this Invention.
Referring to Figures 1 and 2, CD designate the form-cylinders. E E indicate
the impression cylinders which print one side of the web-A, and F F those which
print the other side. Similarly G G mark the impression cylinders which print
one side of the web B, and H H those which print the other side. T U V W
designate carrier-cylinders that lead the web from one impression-cylinder to the
next, so as to present a proper surface of it for the second impression on the same
side; tu turning-bars fixed in different horizontal planes, but placed at right
angles to one another and inclined at an angle to the direction of motion of the
webs and L L mark the rotating cutters for longitudinally dividing or slitting the
webs.
The paths of the webs, completely printed on both sides, may be easily traced.
It is clear that the web A will pass round the roller e and thence be guided to the
turning bar t. It then passes round the turning bar t by which its direction of
travel is changed by a right angle; thence round the roller r, and finally between

page_text: the longitudinal or slitting cutters L L, the lower of which should be a cylinder to
support the webs widthwise. The web B passes round the leading rollers g printed
on one side; thence round the cylinders HW H, thus getting printed on the other
side, and from there round the leading roller h, being now completely printed on
both sides. It next passes round turning bar u and then goes between the
alitting-cutters LL. Thus the webs, after passing through the said slitting-cutters
are divided longitudinally and form two side by side streams, fac-similes of one
another, but one lying one way and the other the other.
It should be observed that the deflecting devices should be arranged so that
when the largest number of pages which can be placed abreast on the printing
cylinders is even, the central lines of the widest webs that can be printed are
brought together; but when the said number is odd, then the longitudinal line of
one web, distant the breadth of a page (measured parallel to the axes of the
printing-cylinders) from the central line, should be brought on to the corresponding
line of the other web; and in both cases it is along the lines so brought together
that the longitudinal severance should take place with or without, according to
circumstances, other lines of severance, as explained in the aforesaid specification.
It is obvious that this Invention applies when the webs are transversely cut
before being printed on, the sheets, of course, being suitably conducted between
tapes.
Transvers cutting, folding, and delivery mechanisms are not shown, nor details
of inking &c; and the printing devices have been briefly described because their
construction and operation is well understood, and they do not form a part of the
present invention.
It is plain that the deflecting mechanism and the deflections which the webs
undergo may be varied indefinitely without departing from the invention.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
In a printing machine, the combination, with mechanism for printing both sides
of two webs, (each web being printed on alike, but with different matter, on
opposite sides of a web,) of mechanism for deflecting the paths of both webs, and
mechanism for longitudinally slitting or dividing them, whereby the similarly
printed sides of the two webs are brought together and they are caused to form
two side-by-side streams, the same in every respect except that the two streams
are reversewise up, all substantially as described.
