Improvements in Insetting and Delivery Attachment for Printing
Machines.
I, JOHN OLIPHANT, Secretary of Lever Brothers Ltd., Soap Works, Port
Sunlight, in the County of Chester, do hereby declare the nature of this invention
to be as follows:-
-
The object of this invention is to provide means whereby it is made possible
for a printing or folding machine to deliver printed matter in double folded
sections, one section inset within the other, instead of single section according to
the principle now usually adopted, and it is the application of this principle of
delivering folded matter inset in double sections which we claim for this invention.
In order to carry out this invention we introduce a mechanism to the delivering
end of the machine whereby a folded sheet of printed matter, as it falls from
the conveying rolls is allowed to remain at rest in a vertical position in "V"
grooves, specially adapted for the purpose, the elasticity of the paper when in
folded condition causing it to spring open and to remain so until a second folded
sheet of printed matter falls from the conveying rolls, and is deposited within the
folds of the first named folded sheet; at this point the flyer carries the whole out
of range; this process is repeated with every delivery of the machine.
DESCRIPTION OF MECHANISM USED.
Our experimental machine is as follows; -The speed of rotation of the shaft
operating the flyers as now used in the ordinary printing or folding machine is
reduced to one half, in order to allow the flyers to make one oscillation in the
time now taken by the flyer in the ordinary machine to make two oscillations.
By 80 doing it allows the first folded sheet of printed matter to remain at rest
vertically supported in the "V" groove, one half of the period taken by the flyers
to make one oscillation. This object is attained by means of gear wheels in ratio
one to two. These actuate the shaft on which is placed an eccentric or an eccentric
and crank. These by means of connecting rods actuate two horizontal shafts which
again by means of bevel gearing actuate vertical ones. On these vertical shafts
are two cranks operating two racks.
These racks by means of segmental toothed wheels operate the flyers causing
them to move through an arc of 180 degrees. Briefly described, the object obtained
by the introduction of the foregoing mechanism is to give motion to paper flyers
such that they oscillate through an arc of 180 degrees, instead of 90 degrees at
a rapidity of oscillation one half that of the ordinary machine, that is to say, they
move 180 degrees in the same period of time now taken to oscillate twice through
an angle of 90 degrees, the ordinary double flyer being substituted by a single
flyer.
The operation of collecting is as follows;-A folded sheet of printed matter
falls from conveying rolls into "V" grooves unfolding itself and remaining in a
vertical position until a second folded sheet passes through the machine, and lodges

page_text: within the folds of the first named folded sheet. During this time the flyers have
passed through an angle of 90 degrees to and fro, and now wipe the two folded
sheets inset one within the other out of range, delivering with every alternate
stroke to left and right. In thus describing our experimental machine, we do
not absolutely bind ourselves to the exact arrangement described, as it is obvious
that in place of a crank and eccentric and two horizontal shafts, two sets
of bevel gear, two vertical shafts and two cranks, a single crank and con-
necting rod, horizontal and vertical shafts and other cranks could in some cases
be substituted. Further, that instead of the segmental gearing and rack moving
the flyers, might be connected direct by link gearing or otherwise with the crank and
vertical shaft for it is obvious that once described an arrangement whereby motion is
conveyed from one moving part to another moving part, and any other ordinary
apparatus for conveying motion can be used which will enable the two moving parts
to have the same relative motion to each other which they have by this mechanism.

Improvements in Insetting and Delivery Attachment for Printing
Machines.
I, JOHN OLIPHANT, Secretary of Lever Brothers Ltd., Soap Works, Port
Sunlight, in the County of Chester, 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 of this invention is to provide means whereby it is made possible
for a printing or folding machine to deliver printed matter in double folded
sections, one section inset within the other, instead of single section according to
the principle now usually adopted, and it is the application of this principle of
delivering folded matter inset in double sections which I claim for this invention.
It has heretofore been customary in the delivery of such folded printed matter
to deliver the same in single form by flyers operating throughout an angle of 90°,
but according to this invention the travel of the flyers is throughout an arc of 180°
and at half the speed of the former. However, I will now proceed to describe my
said invention with reference to the accompanying drawings which form part of
this specification.
In order to carry out this invention I introduce a mechanism to the delivering
end of the machine whereby a folded sheet of printed matter, as it falls from
the conveying roll is allowed to remain at rest in V grooves specially adapted
for the purpose, the elasticity of the paper when in folded condition causing
it to spring open and to remain EO until a second folded sheet
of printed matter falls from the conveying rolls and is deposited within the
folds of the first named folded sheet. At this point a flyer carries the whole out
of range. The process is repeated with every delivery of the machine.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which
Figure 1 is an end elevation of the machine;
Figure 2 a plan;
Figure 3 a part front elevation.

page_text: A are the receiving hoppers or troughs, in which the folded printed matter is
delivered at a central point into the inclined gaps or grooves B. These are of
V shape and located in the position shown. The bed of the hopper A is pro-
vided with concentric openings C throughout an arc of 180°. Through these slots
or openings C the fingers D protrude, said fingers I being formed on or attached
to the flyer E mounted on a vertical axis 1. This axis is provided with a pinion G
to which motion is imparted by the reciprocal movements of the rack H. The
elasticity of the paper of the folded printed matter on being delivered into the
said grooves 13, will cause it to spring open to the angle of the grooves B or
thereabouts and to remain so until a second folded sheet of printed matter is
delivered from the same machine and within the open folds of the first named
folded sheet. At this point the oscillating flyers E sweep the two out of range
while another pair are being delivered into the angular receptacle B whereupon
the return of the flyers take the next pair of folded sheets along to the opposite
extremity of the trough A, and so on with every successive delivery of the
machine.
The speed of the shaft which operates the flyers is by this invention reduced to
one half in order to allow the flyers E to make one oscillation in the time now
taken by the ordinary machine to make two oscillations. By so doing it allows
the first folded sheet of printed matter to remain at rest supported in the V-
grooves B during one half of the period taken by the flyers to make one oscillation.
This object is attained by means of gear wheels in a corresponding ratio and advan-
tageously in the following manner:-
is the frame supporting the shaft H on one end of which is an eccentric P
having a rod Q which connects with the lever R attached to the rock shaft L. This
rock shaft is provided with a mitre wheel M, meshing with a like wheel on the
shaft L' and to which shaft is attached a lever N connected to the toothed rack H
which engages with the sector shaped gear wheel G to which the flyers E are
connected. On the opposite end of the shaft H' is a crank disc I having a wrist
pin to which is attached a rod J connecting with the lever K attached to the
rock shaft which is provided with similar mitre wheels M¹ and connections to
the one previously described. On one end of the counter-shaft H' is a master
gear wheel S which meshes with the pinion T secured to the driving shaft T¹.
Briefly described the object attained by the introduction of the foregoing mechanism
is to give motion to paper flyers so that they shall oscillate through an arc of
180 degrees instead of 90 degrees, at a rapidity of oscillation one half of that of
the ordinary machine, that is to say, they move 180 degrees in the period of time
now taken to operate twice through an angle of 90 degrees, the ordinary double
flyer being substituted by a single flyer.
The operation is as follows:-
The folded sheet of printed matter falls from conveying rollers into V grooves,
unfolding itself and. remaining in position until a second folded sheet passes
through the machine, and lodges within the open folds of the first named folded
sheet. By a sweep of the flyers they wipe the two folded sheets inset one within
the other, out of range, delivering with every alternate stroke to left and right.
In thus describing my experimental machine, I wish it to be understood that I
do not absolutely bind myself to the mechanism described. Further I do not
confine myself to the radial action of the flyers, as the delivery of the printed inset
matter may be effected by a reciprocating set of fivers in a straight path to feed
the printed matter to left and right. The plane of the base of said straight hopper
need not necessarily be horizontal, but may be advantageously inclined so as to
retard their movement along the hopper somewhat, and thereby cause a greater
number of bundles to accumulate in a given space than would be the case were
it
open or horizontal.
A gravity pressure weight rolling down towards the centre
feed could with advantage be employed. It will be obvious that these oscillatory
or reciprocating movements of the flyer can be effected by various forms of
mechanism, as modifications of the means herein shown and described, and to

page_text: which I would have it understood that I do not confine myself. It is obvious that
once describe an arrangement whereby motion is conveyed from one moving part
to another moving part, and any other ordinary apparatus for conveying motion
can be used which will enable the two moving parts to have the same relative
motion to each other which they have by this mechanism.
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. The improvement in insetting attachments for printing machines, comprising
a hopper or trough, gaps or grooves adapted to hold the printed matter transversely
in the hopper and also permit the first portion to open to receive the succeeding
or inset portion, and flyers adapted to oscillate or reciprocate in the hopper so
that immediately a second sheet is delivered into the folds of the first sheet, the
flyers will sweep the two out of range while another pair are being delivered
into the receptacle, whereupon the return of the flyers take the next pair of sheets
along to the opposite extremity of the trough, and so on with every succeeding
delivery of the machine, substantially as described.
2. In insetfing attachments for printing machines, the combination with a
hopper or trough, of angularly shaped grooves or gaps formed midway in or upon
the said hopper or trough and in such a manner as to hold the folds of the sheets
open while the inset portion is delivered thereinto, substantially as and for the
purpose described.
3. In insetting attachments for printing machines, a hopper or trough formed
with radial or semicircularly arranged grooves in the base, in combination with
flyer arms which protrude through the grooves and which in their semicircular or
reciprocal action intermittently sweep the folded and inset matter placed in the
paths to one or the other side of the hopper or trough, substantially as described.
4. In insetting attachments for printing machines, the combinations and
arrangement of gearing and connections for driving the flyers one half the
speed of the main driving shaft, and enable the flyers to travel through an are
of 180° and thereby effect a delivery both in its forward and return movements,
substantially as described.
5. In insetting attachments for printing machines, the combination with a
hopper or receiver having grooves forming a grid or grating at bottom, of
V-shaped grooves or gaps formed at either side of the said hopper to receive the
printed and folded matter on issuing from the printing machine, said printed
matter being swept either to the one side or other of said receiver by the arms or
flyers protruding through the spaces formed by the grating aforesaid, substantially
as & for the purpose herein set forth.
