I, EDWARD THOMAS CLEATHERO, of The Hollies, Barrington Road, Altrincham,
in the County of Chester, Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
The present invention relates to improvements in means for packing or knock-
ing up sheets as they are being delivered one on to another, so as to form a
pile on a delivery board. It is specially applicable to the flyers and delivery
boards of printing machines.
In carrying it into effect, one adjacent side and end fence are moved away
from the side and end fences respectively opposite to them, to receive the sheet;
and are then moved up to them again after the sheet has been delivered, to
knock it up during the time that the flyer is making its return stroke. The
reciprocating motion just described is derived from the flyer shaft or from any
other moving part of the machine, and through any suitable link and lever
mechanism. It is preferred that of the two side fences, the one next to the
flyer shaft shall be the moveable one. Its motion may be either arcual or diagonal
in suitable slotted guides in the delivery table or by means of levers and links.
A link is pivotted
An arcual motion is imparted to it by the following means.
on each end of the said fence, the opposite ends of the links being pivotted on the
delivery board. A rod works in guides on the adjacent side of the said board,
and a link extends from a fixed point on this rod, to a fixed point on the fence.
The rod is moved in one direction by a bell crank lever having its fulcrum.on
the delivery board and its ends connected respectively to the flyer shaft and
the said rod, and in the other by a returning spring. The knocking up motion
of the moveable end fence is linear, the moving side fence and it moving
together. The latter derives its motion from the rod last mentioned through a
lever which has its fulcrum upon the said rod and is adjustable thereon. This
lever has the said end fence pivotted upon its outer end. The working position
of this pivot is adjustable lengthwise of the lever, and the angle which the lever
makes with the rod is also adjustable; so that the working position of the mov-
ing end fence is adjustable according to the position of the fulcrum of the lever
upon the rod; the angle between the said lever and rod; the position length-
wise of the lever, of the pivot that holds the said fence to it; and the position
of the fence itself with reference to the lever.
The remaining side and end fences are fixed when they are in working posi-
5 tion, but the positions are adjustable within wide limits by a link pivotted by
one end on each fence and a lever pivotted by one end on the delivery board,
the lever and link being pivotted together by their free ends. Further, the
positions of the pivots on the delivery board are adjustable farther from or

page_text: nearer to the respectively opposite moving fence. The fixed side fence is pre-
ferably duplicated, by being in two half fences aligned with each other, in order
that long sheets may engage with it near the two corners instead of halfway
along the side.
The positions of the flyer slots upon the flyer rod, are adjustable so that they
can be moved to the right or left thereon to prevent them smearing the wet
print. The opposite and fixed side fence or fences are slotted vertically so as
not to stop the flyer slots when they are delivering.

Improvements in Means for Packing or Knocking Up Sheets as they
are being Delivered on to a Delivery Board, specially applicable to
Printing Machines.
I, EDWARD THOMAS CLEATHERO, of The Hollies, Barrington Road, Altrincham,
in the County of Chester, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly des-
cribed and ascertained in and by the following statement:-
The present invention relates to improvements in means for packing or knock-
ing up sheets as they are being delivered one on to another so as to form a pile
on a delivery board. It is specially applicable to the flyers and delivery boards
of printing machines.
Referring to the accompanying figures which are to be taken as part of this
specification and read therewith:-
Figure 1 is a plan; and
Figure 2 is a front elevation of the present invention showing it applied to
the flyer and delivery board of, say, a printing machine.
Figure 3 is a side elevation of Figures 1 and 2 looking at them from the left
hand:
Figure 4 is a side elevation looking at the same two figures from the right
hand;
The full lines of the preceding figures show the flyers down and the packing
or knocking up boards out of action.
Figure 5 is a plan after removal of the flyers, showing the sheets of the pile
packed or knocked up
Figure 6 is a rear elevation of Figure 5 including the butt ends of the flyers
to show the position which they occupy at the moment the packing or knocking
up has been completed.
1 is the delivery board; 2, the flyer shaft turning with the usual reciprocating
motion in brackets 3, 3; 4, 4, the flyers; 5, the stop bar on which they rest
when they are out of action; 6, and 7, 7, the fixed side and bottom stops
adjustable upon the board 1; 8,. the pile of sheets upon the board 1; and 8, the
last sheet deposited thereon.and waiting to be packed or knocked up. So far
the parts just mentioned are substantially the same as heretofore.
Each stop 6 and 7, 7, is independent of the other to the extent that the adjust-
ment of either is not limited by the position of the other. For this purpose, a
stop is pivotted upon the outer end of a link 9, which has its opposite end

point upon the board 1. The axes of all the said pivots are vertic
so that the links move in a plane parallel with the delivery board, and for t
10 having its opposite end pivotted at a co
purpose of holding the respective stops in the desired position, each pivot
5 provided with a thumb screw 11. Further, the bottom stops 7, 7, are slotte
vertically as shown at 12, to allow of the flyers 4 getting down as near to th
board as may be desirable, and as the position of the slots will vary with the posi
tion of the respective bottom stop, all the flyers 4 are adjustable lengthwise of the
flyer shaft 2, by means of sliding sockets 13 in which their butt ends are res
10 pectively fixed, a set screw 14 in each socket, and a slot 15 in the flyer shaft,
all the sockets 13 being capable of a sliding motion upon the said shaft 2.
16 is the top fence, packer, or knocker up. It is carried by two links 17, 18,
the adjacent ends of which are pivotted to its back at 19, 19, at equal distances
from its ends. The opposite ends of the said links 17, 18, are pivotted upon
5 vertical pivots 20 fixed to the board. 21 is a rod parallel with the top edge of
the said board and capable of a reciprocating sliding motion in lugs 22 pro-
jecting therefrom. It is moved in one direction by the rock of the flyer shaft 2
to raise the flyers 4, winding up the chain 23. The latter is fast to the said
shaft 2 by one end, and by the other to one end of a bell crank lever 24, having
its fulcrum in a pillar block 25 fast on the board 1 and its opposite end con-
nected by a link 26 to the adjacent end of the rod 21. 27 is a link having one
end pivotted by the pivot 28 fast on the rod 21 and the other end pivotted at 29
on the back of the fence 16, preferably in the relative positions with regard
to the two links 17, 18, that
flyers 4 are raised the fence 16 is moved diagonally over the board 1 towards
shown in Figures 1 and 5. So that each time the
the angle between the stop 6 and the stops 7, 7, packing up accordingly the
sheet 8 just laid down by the flyers 4 on the pile 8.
30 is the movable end fence. It is worked to and from the opposite stop 6,
not diagonally but in a direction parallel with the rod 21, by being made
ast to the latter by an arm 31. The latter is fixed to a block 32 capable, of
ongitudinal adjustment along the rod 21, by means of a set screw 33 passing
own through the said block into a groove 34 in the rod 21. The screw 33 also
erves as a pivot for adjusting the angle at which the arm 31 stands with the
id rod 21, that arm being held in the adjusted position by a thumb screw 35
orking through an arcual slot 36 in the said arm 31 down into an extension
the block 32. The fence 30 is connected to the respective end of the arm 31
means of a bracket 37 fast to its back, a longitudinal slot 38 in the arm 31
d a thumb screw 39 working down through the said slot 38 into the bracket 37.
The fence 30 is thereby capable of considerable adjustment, ifs working
ition depending upon the angle which the arm 31 makes with the rod 21,
position of the block 32 on the said rod, the position lengthwise of the
31 of the screw 39 and the position of the fence 30 with reference to the
31. This fence, packer, or knocker up 30 is put through its packing or
cking up motion simultaneously with that of the top fence 16-they both
ck up and retire together. This is clearly indicated in Figures 5 and 6, and
d 2, the two former showing the end of the knocking up motions, and the
latter the end. of the retiring motions.
is a spring around the rod 21 and resilient between one of the lugs 22 and
ivot 28. It serves to return the two fences 16 and 30 to their normal
ons as the flyers 4 are rocked down to lay a fresh sheet on the pile.
sing now particularly described and ascertained the nature of my said
ion and in what manner the same is to be performed, I declare that what
m is:-
he hereinbefore described combination of fiver shaft. Arena
dinally thereon and adjustable clotte

page_text: 2. The herein before described combination of movable top fence; adjustable
and movable side fence; and mechanism for putting them both through their
respective packing or knocking up motions simultaneously in the respective
directions described.
