JOHN JOWETT, 5, Adelphi Street, Burnley, Lancashire, Printer, do hereby
declare the nature of this invention to be as follows:-
-:
This invention relates to an improved mechanical apparatus for adjusting &
keeping in a straight pile, the sheets of paper as they are delivered from the
flyers of printing machines.
Attached to the delivery board of the printing machine & at right angles to
each other are two fixed but adjustable gauges which slide up suitable guides
fixed on the delivery board & can be clamped at any position (to suit the size of
sheet operated upon) by a thumb or set screw. These form two sides of a rectangle
into which the sheets are delivered by the flyer & against which the sheets are
pushed by the other moving sides of the rectangle. The other two moving sides
of the rectanle are fixed together & form a square one side of which can be
adjusted along the other side & clamped to it at any part by a thumb or set
& to facilitate this, one is provided with a suitable bracket which slides along a
suitable guideway on the other. The square consisting of the two beating up
gauges one adjustable along the other, is arranged to swing on two equal radial
arms which turn in bearings attached to the delivery board & moves in the path
of the arc of a circle commencing when the arms are parallel with the back side
of the square or that side which is parallel with the flyer shaft.
The adjustable moving square thus pushing the sheets home against the two
fixed gauges forming two sides of the rectangle. Thus the movement of both
moving sides is combined in one, by the action of the square moving in the arc
of a circle. The reciprocating motion of the radial arms can secured by placing
a cam or eccentric on the fiver shaft which presses against one of the radial
arms when the cam or eccentric part is passing the centre of the shaft, the radial
arm being kent against the eccentric by a spring, or the radial arm might be
provided with a U shaped cup in which the eccentric turns & thus give a positive
reciprocating motion to the radial arms in the arc of a circle. The action of
the adiuster is as follows viz. When the sheet is being delivered by the flyer
the rectangle opens but closes up as the flyer goes back to receive another sheet,
or by setting the eccentric with its full side at right angles to the flyer the
rectangle closes twice for each sheet delivered, thus both sides of the moving
square give a double knock & still is out of the way or is open when the sheet
is delivered. The side of the square which is parrallel to flyer shaft keeps parallel
owing to its swinging or equal arms.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention has reference to new and improved mechanism for adjusting and
keeping in a straight pile, sheets of paper as they are delivered from the flyer
of printing machines. My invention is so arranged, that instead of having two
or more distinct movements of the beating-up boards as in other machines, the
sheets of paper are adjusted and beaten up perfectly parallel and straight by one
movement only, two beating-up boards for this purpose moving in unison and
simultaneously together against two adjacent sides of the sheets of paper from
one source of operation, the object being thereby to give a corner knock or jog
to the sheets of paper, whereby a considerable simplification of mechanism is
effected, a reduction of cost is brought about, and the attendant may more readily
set the adjuster to different gauges for various sizes of sheets than possible with
other types of adjusters at present in use.
With this object in view, I connect the two beating up boards at right angles
to each other, and they are preferably fixed on the respective limbs of a L shaped
tubular bracket, through one limb of which a rod is passed, by which the
requisite beating up motion is given to the beating up boards. The tubular
bracket is capable of sliding, and is adjustable in any position upon the said rod,
by means of a thumb screw. Further, the end board is capable of extension in
width by an additional board carrying a rod, which enters the tubular limb of
the bracket, and is also adjustable in any desired position by a set or thumb
screw.
This operating rod is preferably arranged to move in a parallel line, or approxi-
mately so, with the flyer shaft of the printing machine, and is actuated by two
radial arms, suitably jointed to the said rod. One of the said radial arms carries
a vertical pin or stud, which is acted upon by a wiper, cam, eccentric or the like
on the flyer shaft of the printing machine, or may be operated from another
source in such a manner as to cause the radial arms to describe the arc of a
circle, and give a parallel and end movement to the rod, with which they are
connected, thus knocking up evenly the sheets of paper against two stationary
guide plates of novel construction. A spring acting upon one of the radial arms
returns the beating up boards to their normal position.
One of these guide plates is backed by a tubular L bracket, one limb of which
is capable of sliding and adjustable in any position upon a rod carried by a bracket
to which is fixed the other guide board. Through a boss in the latter bracket,
the said rod is passed and adjustable thereon by a thumb screw, the said bracket
being also curved at the bottom so as to be capable of sliding and adjustable upon
a guide bar secured by screws to the delivery table of the machine. The guide
plates may thus be readily expanded or contracted to any desired degree either
inwards or outwards to admit of different sizes of sheets being evenly knocked up.
My invention will be fully understood by reference to the accompanying draw-
ings, in which A and B are the two beating-up boards fixed to the respective
limbs of the tubular L bracket C, and adjustable as desired either forward or
backward upon the operating rod D by the thumb screw E. An additional
board F, carries rod Ġ pushed into the other extremity of tubular bracket.C,
and adjustable thereon by set screw H so as to extend the beating up board B
at this side to suit various sizes or widths of paper.
The operating rod D derives its motion, which is approximately parallel to the
flyer shaft J and also an end movement through the medium of the radial arms K
and L, which swivel upon jointing pieces M secured to the operating rod D) by
set screws, such radial arms in their movement describing the arc of a circle.
The radial arm. K moves on the stud K¹ passed through the delivery board
and having fixed to it and underneath such board a short arnt O¹ acted upon by
spring P, which returns the arms, and consequently the beating-up boards, to
their normal position after each knock up.
The radial arm L is pivotted to the bracket Q fixed to the delivery board, and

page_text: carries projecting pin Q¹ which is acted upon by a wiper or the like R carrying
anti-friction bowl R', which wiper is secured to the flyer shaft J of the printing
machine.
With the forward movement of the flyer in the act of delivering a sheet, the
said wiper R forces forward the radial arm L, which, through its connections
with the rod D and radial arm K, gives the required parallel and end
movement to the beating up boards A B and F, and effecting the knock up, the
said radial arms describing the arc of a circle. The spring P returns the arms
and boards to their normal position as described. With the backward movement
of the flyer, the pin Q is again struck by the wiper R, thus giving a double
knock to the sheets with each delivery. It will be observed, that a corner knock is
given to the sheets of paper, and that the beat up is effected from two adjacent
sides simultaneously.
The sheets of paper are beaten up against the stationary guide plates S and S¹.
The guide plate S is backed by a shaped tubular bracket T, which is adjust-
able by a set screw on the rod T carried by the bracket U, through a boss in
which the said rod is passed and secured by a set screw, whereby it is also
adjustable. The bracket U carries the guide plate S', and is slotted to slide and
be secured in any position upon the guide bar V fixed to the delivery board by
screws as shewn. By such arrangement of the respective guide plates, they may
be readily adjusted to suit various sizes of paper sheets.
In a modification, the guide plate S may be dispensed with, and a third beat-
ing-up board adjustably secured to the operating rod D at that side, in such a
way that when the boards A and B are knocking up the sheets of paper, the said
additional or third board will be out of action, and vice versa.
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 improved means of adjusting sheets of paper as they are delivered from
printing machines, whereby a corner knock is effected to two adjacent sides of
the paper with one movement of the bearing up boards, substantially as described
and shewn on the drawing.
2. In sheet adjusters for printing machines, the radial arms K and L, operating
rod 1), and spring P in combination with beating up boards such as A and B,
arranged and acting substantially as described and shewn upon the drawing.
3. In sheet adjusters, the L bracket C in combination with beating up boards
such as A and B for facilitating the adjustability of such boards upon rod D, and
either with or without the adjustable extension board F, substantially as
described, and illustrated.
4. The improved form and construction of stationary guide plates of sheet
adjusters for printing machines, and the means whereby they are adjusted to suit
various sizes of paper, (excepting so far as regards the movement of the bracket U
upon the guide bar V), substantially as described, and illustrated.
5. The general arrangement and combination of parts of a sheet adjuster for
printing machines, substantially as described and shewn upon the drawing.
