IMPROVEMENTS IN APPARATUS OR APPLIANCES FOR COLLECTING AND DELIVERING SHEETS OF PAPER FROM PRINTING PRESSES
Year: 1884

page_text: I, GEORGE ASHLEY WILSON, of Liverpool, in the county of Lancaster, Engineer,
do hereby declare the nature of my said invention for IMPROVEMENTS IN APPARATUS
OR APPLIANCES FOR COLLECTING AND DELIVERING SHEETS OF PAPER FROM PRINTING
PRESSES to be as follows:-
The main objects are to provide simple durable and efficient apparatus or
appliances for collecting sheets of paper as they issue from printing presses, mainly
rotary web perfecting machines, and delivering the sheets so collected in piles of
two or more generally thirteen to a fly or layer of any usual or suitable kind or to
folding cylinders or mechanism.
The apparatus or appliances consist essentially of a grooved collecting drum two
sets of carrying tapes and rollers arranged in novel manner and a switch actuated
by improved gear.
*
One set of carrying tapes is led from a roller at the printing press end to the
collecting drum nearly round the latter and thence to the laying or folding
mechanism. The other set of tapes is led from a roller close to the above mentioned
one at the printing press end to the collecting drum and thence directly to the
laying or folding mechanism. The rollers referred to are carrying rollers and aro.
fewer or more in number as occasion requires.
The switch is hung or carried on a pivot or in bearings and is held in contact
with the drum in the grooves by means of a spring or equivalent device. It is
advantageous to use one of the tape carrying rollers or a shaft carrying roller to
carry the switch The said switch is caused to move to and from the collecting
drum by means of a pawl actuated by a bell crank or other lever once for each
double revolution of the said collecting drum. Two papers are in this way collected
and delivered together. More than one switch may be used with each drum. In
addition to the mechanism for giving uniform motion to the pawl, cams or like
devices are arranged to act on the pawl when required and prevent its motion
except at lengthened intervals of time. When such are used three or more
preferably thirteen papers are collected and delivered the number being determined
by the adjustment of the switch.

page_text: I GEORGE ASHLEY WILSON of Broad Green near Liverpool in the County of
Lancaster, Engineer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN APPARATUS OR APPLIANCES FOR COLLECTING AND DELIVERING SHEETS
OF PAPER FROM PRINTING PRESSES, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The main objects are to provide simple durable and efficient apparatus or
appliances for collecting sheets of paper as they issue from printing presses, mainly
rotary web perfecting machines, and delivering the sheets so collected in piles of
two or more generally thirteen to a fly or layer of any usual or suitable kind or to
folding cylinders or mechanism.
The apparatus or appliances consist essentially of a grooved collecting drum two
sets of carrying tapes and rollers arranged in novel manner, and a switch actuated
by improved gear.
One set of carrying tapes is led from a roller at the printing press end to the
collecting drum, nearly round the latter and thence to the laying or folding
mechanism. The other set of tapes is led from a roller close to the above mentioned
one at the printing press end to the collecting drum and thence directly to the
laying or folding mechanism. The rollers referred to are carrying rollers and are
fewer or more in number as occasion requires.
The switch is hung or carried on a pivot or in bearings and is held in contact
with the drum in the grooves by means of a spring or equivalent device. It is
advantageous to use one of the tape carrying rollers or a shafts carrying roller to
carry the switch. The said switch is caused to move to and from the collecting
drum by means of a pawl or equivalent device actuated by a bell crank or other
lever once for each double revolution of the said collecting drum. Two papers are
in this way collected and delivered together. More than one switch may be used
with each drum.
The view hereunto annexed is illustrative of apparatus constructed in accordance
with my invention the various parts being only shown in outline as they are of
themselves well known in connection with rotary printing presses; the novelty
consisting in the arrangement and combination of the parts. a represents a
collecting drum with circumferential grooves b b₁ are two sets of carrying tapes;
the tapes bare led from a roller c where the papers are received from the printing
press past the roller d to and nearly around the collecting drum a thence around
the roller c where the papers are delivered to the laying or folding mechanism and
back over the rollers to the roller c; the tapes 6¹ are led from the roller g close to
the roller c where the papers are received from the printing press to the collecting
drum a around the roller h thence direct to the roller i close to the roller e where
the papers are delivered to the laying or folding mechanism and back to the
roller g.
l
The switch j is carried on the roller shaft h, is provided with projections which
fit into the grooves on the drum and is held in contact with the said drum by the
spring attached to an overhanging portion of the said switch or to the disc n and
to the frame carrying the drum and rollers; pawl on one arm of the bell crank
lever m carried by the roller shaft h. The said pawl takes into a notch on the
disc n attached to the switch; to the other end of the bell crank lever ma
connecting rod o actuated by a cam 2 is attached. The cam p is geared to any

page_text: convenient moving part of the printing press or laying or folding mechanism so as
to actuate the pawl once for each double revolution of the drum a and allow the
projections of the switch to enter the grooves of the said drum. In this manner
two papers following each other between the rollers c and g and the tapes b b' are
collected one over the other on the drum a and are delivered together between the
said tapes b and b¹ and rollers ie. to the laying or folding mechanism.
In addition to the mechanism for giving uniform motion to the pawl, cams or
like devices are arranged to act in any well known or suitable way on the pawl
when required and prevent its motion except at lengthened intervals of time.
When such are used three or more preferably thirteen papers are collected and
delivered, the number being determined by the adjustment of the switch.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
First. The combination with rotary printing presses of a collecting drum with
tapes and rollers arranged substantially as setforth.
Second The combination with a collecting drum for rotary printing presses of a
switch with pawl actuating mechanism constructed and operating substantially as
setforth.
