The invention relates to rotary web perfecting, and folding machines that is to
say to machines in which a web of paper is printed on both sides, cut into sheets of
the required size and folded once or oftener before delivery.
The main objects are to simplify the construction of various parts and to render
them more efficient and trustworthy in action.
Under the first part I construct a stereotype cylinder with reduced ends and
cut or form screwthreads on such reduced ends, I then fit on the said screw threads
flanged nuts so contrived that when screwed up they press against, overlap and hold
the stereotype in its place on the cylinder.
Under the second part. I fit a cam or cams in the interior of a rotary folding
cylinder and arrange such cam or cams to give motion to one or more blades or
blade carriers when the folding cylinder is caused to rotate. The blades are either
gripping or folding blades or both.
Under the third part, I secure the cams above mentioned on shafts working in
bearings secured to or forming part of the ends of the folding cylinders and I provide
the said shafts with toothed wheels to gear and be used in combination with toothed
wheels on the shafts carrying the folding cylinders.
Under the fourth part. One or more of the cam shafts of folding cylinders is or
are connected with the driving gear by means of catches or equivalent devices, so
that the relative position of such shaft or shafts and the driving gear may be
altered and the time of action altered so as to allow of newspapers of whole or half
size being printed and folded on the same machine.

1. The Invention relates to rotary web perfecting and folding machines that is to
say to, Machines in which a Web of Paper is printed on both sides, cut into sheets
of the required size and folded once or oftener before delivery.
2. The main objects are to simplify the construction of various parts and to render
them more efficient and trustworthy in action.
3. Under the first part I construct a Stereotype Cylinder with reduced ends and
cut or form screw threads on such reduced ends I then fit on the said screw threads
flanged nuts so constructed that when screwed up they press against overlap and
hold the stereotype in its place on the Cylinder.

may be in separate pieces as shown at f¹ f2 figure 2. h. bearings i, guides
j, springs, k, set screws. The impression Cylinders l, are also made with reduced
ends and flanged nuts.
4. Under the second part I fit a cam or cams in the interior of a rotary folding
cylinder and arrange such cam or cams to give motion to one or more blades or
blade carriers when the folding Cylinder is caused to rotate. The blades are either
gripping or folding blades or both.
5. Under the third part I secure the cams above mentioned on shafts working in
bearings secured to or forming part of the ends of the folding cylinders and I
provide the said shafts with toothed wheels to gear and be used in combination
with toothed wheels on the shafts carrying the folding cylinders.
6. Under the fourth part One or more of the cam shafts of folding cylinders is or
are connected with the driving gear by means of catches or equivalent devices, so
that the relative position of such shaft or shafts and the driving gear may be
altered and the time of action altered so as to allow of Newspapers of whole or half
size being printed and folded on the same machine.
Figure 3 is an end view partly in section figure 4 a longitudinal section of
apparatus illustrative of the second third and fourth parts of my invention 1 part
of frame of machine to which the folding apparatus is fitted 2 shafts of folding
cylinders; each shaft is provided with a toothed wheel 3 fitting loosely thereon
and made or formed with an arm 4 The lower end of each arm is secured to the
frame 1 or in any convenient way so as to prevent the wheels 3 from turning
when the shaft 1 revolves. 5 are the folding cylinders of cast iron with slots 6
through which the folding and gripping blades work The Cylinder ends 7 are
bolted to the Cylinders and keyed on the shafts. 8 are bearings in the ends of
the cylinders for carrying the shafts 9, 10, 11, 12 and 13 On the ends of the said
shafts are secured toothed wheels 14 which gear into the stationary wheels 4 and
cause the shafts to rotate when the Cylinder is revolving All the wheels are the
same size and have the same number of teeth so that each shaft rotates once for
each revolution of the Cylinder The shafts are cam shaped within the Cylinder
so as to give motion to the blade carriers 15. hinged at 10 to bearings secured on
the shafts 2. Helical springs on guides 17 secured to the Cylinders 5 keep the

page_text: carriers 15 in contact with the cam shafts 18 are folding blades and 19 gripping
blades secured to the carriers 15 by set screws or equivalent means
20 knife
21 moveable piece. 22 paul or catch secured to the wheel 14 which is loose on the
shaft 9 of the upper cylinder 23 disc secured to the shaft 9 and made with two
recesses to receive the paul 22. The shaft 13 of the lower cylinder and its driving
wheel are similarly connected-The third cylinder 24 for giving a second fold to
large papers is fitted with a single gripping blade operated through a cam shaft
and wheels 14 and 3 in manner similar to that described for the other two
cylinders.
The cylinders are shown arranged for folding papers the length of which is
equal to the circumference of the Cylinders The knife 20 in the lower Cylinder
cuts off a sheet from a printed web at each revolution After the paper has been
cut and the Cylinders have rotated a small distance the folding blade 18 operated
by the shaft 13 in the upper cylinder pushes a portion of the leading edge of the
sheet between the upper blade 19 operated by the shaft 13 of the lower cylinder
and the edge of the slot in which the blade works the leading edge of the sheet is
carried round during the rotation of the cylinders until they are in the position
shown by the drawings at about which position the said leading edge is released
at the same time the folding blade operated by the shaft 11 of the lower cylinder
pushes the paper between the gripper of the shaft 11. of the upper cylinder and
the edge of the slot in which it works. The centre of the sheet is carried by the
before mentioned gripper of the upper cylinder between it and the third cylinder 24
and the first fold is made. Whilst the middle of the sheet is being carried forward
by the upper cylinder the tail edge is caught by the grippers of the shaft 10 of
the lower cylinders and carried forward until the folded centre of the sheet is part
the line of contact of the second and third cylinders When the folded sheet has
been carried half round the upper cylinder the folding blade worked by shaft 9
forces the centre of the sheet into the grippers. of the third cylinder which carries
it away and produces the second fold
When it is desired to fold sheets of half the length of the circumference of the
lower cylinder the piece 21 is removed and a knife substituted for the folder 18
The positions of the shaft 9 and wheel 14 of the upper cylinder 5 and the shaft 13
and wheel 14 of the lower cylinder are altered by raising the pauls 22 and turning
round the shaft whilst the wheel remains stationary until the pauls enters the
recesses in the opposite side-of the disc 23 when so arranged The shafts 9 and 12
of the lower roller operate folding grippers and the shafts 10 and 13 both
operate grippers for folding the leading edge of the sheet Two blades 18 of the
upper cylinder act as folding and two as gripping blades The alteration of the
positions of the shafts and wheels above mentioned carries the blades receiving
motion from such shaft to act at times suitable for folding papers in length half
the circumference of the cylinders and this is effected by the blade carriers 15
bearing during any given part of the revolution of the shafts 9. 13 on different
portions of the cam surface thereof as will be obvious. The half size sheets when
folded by the two Cylinders 5 are carried away between the upper and third
cylinder without receiving a third fold as the times of folding are so altered that
the gripping blade of the third cylinder does not come into action.
Having now described and particularized the nature of my said Invention in
such manner that others will be enabled to carry my improvements into effect.
I claim
First. Stereotype Cylinders with reduced ends cut or formed with screw
threads and provided with a flanged nut or its equivalent substantially in
the manner and for the purpose setforth.
Second. Folding Cylinders with internal cam shafts and cams giving motion
to blade carriers substantially as setforth.
Third. Folding Cylinders fitted internally with cams and shafts carried in
bearings in the Cylinder ends and actuated by toothed gearing substantially
as setforth.

page_text: Fourth. Cam shafts fitted in folding cylinders provided with driving wheels
६ and and connected thereto by pauls or catches substantially in the manner and
for the purposes setforth on shafts 9 and 13, and
Fifth, Folding Cylinders fitted with folding and gripping blades substantially
as setforth.
In witness whereof I the said George Ashley Wilson have hereunto set my
hand and seal this sixteenth day of January in the year of our Lord One thousand
eight bündred and eighty four.
