Fig. 5 is a detail view of the device for carrying on the paper:
The bases or tables B' and B' are immovably fixed onto the uprights or frame-
work A and A' of the machine and they respectively carry a form or set up
type X1 for the first and X' for the second impression of the sheet.
The pressure cylinders C and C² move over these tables pressing both in their
forward and backward travel..
The two cylinders turn (i.e. are journalled) in the bearings D' D' and D' D'
provided at the sides of the frame.
The bearings D' D' are moved by the connecting rods E¹ and E the latter
being driven on one side by the main driving wheel F and on the other by the
crank wheel F power being transmitted to the press through the fast and loose
pulleys y and the driving wheel z.
The pressure cylinders C' and Care connected by means of the rods G¹
and G.
Each. of the cylinders C C is further provided with a toothed wheelic c
and cat each end of which the first mentioned toothed wheels run on the fixed
toothed racks ee and the latter on the fixed toothed racks ee. In this manner
a rolling and compressive action is imparted to the cylinders.
The form or set-up type X for the first impression receives its ink from the
inking rollers H' to H supported in slots or bearings provided. in the bearings D'
and D of these the rollers H to H ink the form during the forward motion of
the cylinder and the rollers H' to H on its backward motion.
In the same manner the form X for the second impression is supplied with ink
by similar sets of inking rollers.J to J during both the forward and backward
motion of the cylinder:
The inking of the rollers H' to H is effected by means of an inking apparatus
consisting of the set of cylinders M' to Me whilst the inking apparatus consisting
of the set of cylinders N' to N° serves a similar purpose for the rollers J¹ to Jo.
The paper is fed through in the following manner.
The continuous length of paper on leaving the roll o is first carried over the
guide rollers p' and p' which are supported in the uprights or frame of the machine
and over the rollers q¹ and 9 which turn in the bearings D¹ and D' pass under or

page_text: partly round the cylinder C and passing over the rollers and which likewise
turn in the bearings D and D' it then winds round the carrying-on rollers s' t. s.
After this the paper runs over a tension roller t to the rollers u' and u' which turn
in the bearings D D then it passes round the cylinder C' and over the rollers &¹
and and runs finally over the roller to which is supported in the frame of the
machine.
From here the paper is led to the carrying-on rollers and and the
perforating device y' and then continues through the rollers 2 to 3 which divide
it at the perforations when it is carried either to a folding or laying out apparatus
suitably arranged on the press.
The paper which is fed into the machine in the manner above described is
printed on one side whilst the cylinder C' is advancing from position I to
position II shown in dotted lines in Fig. 4. When the cylinder C₁ has reached the
position II and before its return the carrying-on rollers & to are caused to
rotate by means of the toothed segments 1 and 2 arranged on the driving wheel F
and so to advance the paper a distance corresponding to the length of the said
segments; so that by employing segments of different lengths the paper can be sɔ
advanced as to form sheets of any desired size.
The paper which has now received its impression on one side now passes on and
ultimately round the cylinder and there receives its impression on the other
side and is then drawn through the carrying-on rollers and " which move
simultaneously with the carrying-on rollers s¹ to s' and after passing through the
perforating device is carried to the laying-out apparatus.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is ;-
1. A press adapted for printing on both sides of a continuous sheet of paper-
having in combination two fixed bases or tables arranged one behind the other to
carry the form, two pressure cylinders adapted to move to and fro over said tables,
means to guide the continuous sheet of paper round each such cylinder, means to
impart the aforesaid reciprocal motion to said cylinders rolling motion being
imparted to the cylinders by means of toothed wheels arranged on the extremities
of said cylinders which wheels engage in fixed toothed racks provided on the
machine all substantially as and for the purposes described.
2. In a press as claimed above a device at the rear of each pressure cylinder
for drawing or carrying on the paper such device being adapted to advance the
paper after each impression the length of the sheet which is being printed this
length being capable of regulation to the length of any sized sheet desired to be
printed by the employment of toothed segments of suitably corresponding lengths
substantially in the manner and for the purposes hereinbefore described.
3. The improved printing press arranged constructed combined and acting
substantially in the manner and for the purposes hereinbefore described and
illustrated in the drawings hereunto annexed.
