PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Folding and Collecting Printed
Sheets of Paper.
I GEORGE ASHLEY WILSON of Broad Green in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object is to provide simple apparatus which will occupy reduced space and
with accuracy fold and collect or associate folded sheets, and then fold such
collected or associated sheets together.
Apparatus under my invention consists in the combination of at least three
rotating cylinders the first of which is provided with a creasing blade, the second
with at least two grippers side by side each arranged to act conjointly with the
creasing blade of the first cylinder, the second cylinder is further provided with a
creasing blade which acts conjointly with grippers in the third cylinder, tail
grippers and the usual driving mechanism are provided.
The action of the apparatus is as follows:-A sheet is carried forward by the
first cylinder and is seized by the grippers in the second cylinder, and carried
round folded until a second sheet is brought forward by the first cylinder and is
seized by the grippers of the second cylinder both sheets being carried round
with their folded edges together until they are seized by the grippers of the third
cylinder and are folded together.
Dated this Fourteenth day of February 1891.
COMPLETE SPECIFICATION.
Improvements in Apparatus for Folding and Collecting Printed
Sheets of Paper.
I GEORGE ASHLEY WILSON of Broad Green in the County of Lancaster,
Engineer do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object is to provide simple apparatus which will occupy reduced space and
with accuracy fold and collect or associate folded sheets, and then fold such
collected or associated sheets together.
Apparatus under my invention consists in the combination of at least three
rotating cylinders the first of which is provided with a creasing blade, the second
with at least two grippers side by side each arranged to act conjointly with the
creasing blade of the first cylinder, the second cylinder is further provided with a
creasing blade which acts conjointly with grippers in the third cylinder, tail
grippers and the usual driving mechanism are provided.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2 are elevations at right angles to each other and Fig. 3 is a
transverse section of apparatus constructed in accordance with my invention. a is
the first cylinder provided with a tail gripper b and folder creasing blade c. d is the
second cylinder provided with two folder grippers ef side by side formed of inter-
spaced fingers and with a tail gripper creasing blade y and folder creasing blade h.
[Price Bl

page_text: i is the third cylinder provided with a folder gripper j. The grippers b, e, and j
are secured on shafts k and are operated by arms and cams -m in the usual way,
the gripper fingers fare carried on sleeves n on the shaft k¹ and are operated by
an arm and cam m¹ through a shaft 2 and segmental pieces o, one pair to each
sleeve. The cam m on the third cylinder has an oscillating motion imparted to it
by means of the gear wheels and connecting rod p, so that it only operates to seize
the paper at each second revolution.
The cams m and m' are caused to revolve by the toothed wheels p, q at a slower
speed than the cylinder d so as to operate the grippers e and fat the proper times.
The action of the apparatus is as follows:
-
The leading edge of the sheet is seized by the tail gripper 6 and is carried round
to the position shown. The gripper f then seizes the centre of the sheet cut off in
the usual way, and carries it into the position shown on cylinder d. The gripper e
then seizes the centre of a second sheet and both folded sheets are carried round
until their centres are seized by the gripperj on cylinder i when both sheets are
delivered folded together.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of three or more rotating cylinders provided with creasing
blades and grippers disposed and operating substantially in the manner and for the
purpose set forth.
