Paper Making Machines, and in the Mechanism therefor.
We, WILLIAM ARCHIBALD, Manager, and JOSEPH PURDIE, Engineer, both of
Springfield Paper Mills, Polton, in the County of Midlothian, North Britain, do
hereby declare the nature of the said invention for IMPROVEMENTS IN SHIFTING
AND ADJUSTING THE DECKLE FRAMES OF PAPER MAKING MACHINES AND IN THE
MECHANISM THEREFOR to be as follows:-
This Invention, which relates to improvements in shifting and adjusting the
Deckle Frames of Paper Making Machines, and in the mechanism therefor has for
its object the shifting of the Deckle Frames of Paper Making Machines and the
altering the width of web of Paper being made thereon, without the Machine being
stopped, and thereby saving much time, loss of fibre, and waste generally.
In carrying this Invention into practice, in substitution for the long Deckle
Frame generally in use upon a Paper Making Machine there is provided a short
Frame preferably of brass and about 2 feet long. This frame is cast or otherwise
formed with a recess of about 10 inches long or of such length as will receive the
Deckle strap pulley. The ends of this frame are made plain, the end in front of
the recess being connected to the wooden or other elbow to which the breast apron
is attached. This elbow is fixed to the long bar of wood or of other material which
slides along a dovetail in the breast board of the Paper Making Machine.
The end of the frame in front of the recess has a small dovetail cast, or otherwiso
formed in it, in this dovetail the slice, which levels the flow of pulp on the Machine
is placed.
In the centre of this recess and at its proper height, is fixed a hollow socket of
brass of or about 2 inches diameter, on this socket the Deckle strap pulley revolves,
and through the hollow centre of the said socket is inserted a screw by which the
Deckle Strap pulley can be pushed in or drawn out as required.
The Deckle frame for the opposite side of the Machine, is made in a manner
similar to that hereinbefore described, and is also similarly fixed to the elbow or
the Breast Board, and provided with a dovetail for the slice; but the screw through
the socket on the recess is preferably left handed, that is to say, the reverse of that
in front, so that when turned from any side of the Machine the Deckle frames are
shifted out or in by one action of the screw.

page_text: The screws through these sockets are made of such a length as to meet at the
centre of the Machine, where they are connected by an ordinary coupling in such
manner as to form one rigid rod across the Machine, but if desired to vary the
Deckle frames at the front and the back, this coupling can be released and the
screws turned from the front and the back of the Machine to any point desired.
The coupling and the outside and inside faces of the sockets are fitted with nuts
on the screws, which, when the Deckle frames are properly adjusted, are tightened
up and act as lock nuts and so prevent the shifting of these parts from vibration
or from other cause.
•
The elbow on the breast board is also provided with a brass hinge so as to
accommodate it to the shake or vibration of the Machine.
The screws project from the Deckle frames, outwards over the shake bars of the
Machine, and are supported in bearings or eyes formed in the upper part of small
standards, a hand wheel being provided on the ends thereof for working the said
screws.

We, WILLIAM ARCHIBALD, Manager, and JOSEPH PURDIE, Engineer, both of
Springfield Paper Mills, Polton, in the County of Midlothian, North Britain, do
hereby declare the nature of our invention for IMPROVEMENTS IN SHIFTING AND
ADJUSTING THE DECKLE FRAMES OF PAPER MAKING MACHINES AND IN THE
MECHANISM THEREFOR and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our Invention, which relates to improvements in shifting and adjusting the
Deckle frames of Paper making machines, and in the mechanism therefor has for
its object the shifting of the Deckle Frames of Paper Making Machines and the
altering the width of web of paper being made thereon, without the machine being
stopped, and thereby saving much time, loss of fibre and preventing waste
generally.
In carrying this Invention into practice, in substitution for the long Deckle
Frame generally in use, upon a paper making machine, there is provided a short
Frame preferably of brass and about 2 feet long. This frame is cast or otherwise
formed with a recess of about 10 inches long or of such length as will receive the
Deckle strap pulley. The ends of this frame are made plain, one end is connected
to the wooden or other elbow, and the other or opposite end of the said frame has
a small dovetail cast, or otherwise formed in it. In this dovetail the slice, which
levels the flow of pulp on the machine, is placed.
In the centre of this recess an at its proper height, is fixed a hollow socket of
brass of or about 2 inches diameter, on this socket the Deckle strap pulley
revolves, and through the hollow centre of the said socket is inserted a screw by
which the Deckle strap pulley can be pushed in or drawn out as required.
The Deckle frame for the opposite side of the machine, is made in a manner
similar to that herein before described, and is also similarly fixed to the elbow, and
provided with a dovetail for the slice; but the screw through the socket on the
recess is preferably left-handed, that is to say, the reverse of that in front, so that
when turned from any side of the machine, the Deckle Frames are shifted out or
in by one action of the screw.
The screws through these sockets are made of such a length as to meet at the
centre of the machine, where they are connected by a coupling in such manner as
to form one rigid rod across the machine, but if desired to vary the Deckle frames
at the front and the back, this coupling can be released and the screws turned from
the front and the back of the machine to any point desired.
The right and left handed screwed shafts are provided with nuts which, when
the Deckle frames are properly adjusted, are tightened up and act as lock nuts and
so prevent the shifting of these parts from vibration or from other cause.
The elbow on the breast board is provided with a brass hinge or its equivalent
so as to accommodate it to the shake or vibration of the machine.
The screws project from the Deckle frames, outwards over the shake bars of the
machine, and are supported in bearings or eyes formed in the upper part of small

page_text: standards, a hand wheel being provided on the ends thereof for working the said
screws.
In order that our Invention may be properly understood and readily carried
into effect, we will now proceed to describe the drawings hereunto annexed :-
Figure 1, is a view partly in plan and partly in horizontal section of portion of
a paper making machine, with our improved apparatus attached.
Figure 2, is a view of the same partly in side elevation and partly in longitudinal
section.
Figures 3 and 4 are respectively a part longitudinal section and part horizontal
section of the same drawn to an enlarged scale.
Figures 5 and 6 are views of detached portions of the same also drawn to an
enlarged scale and all hereinafter more particularly described.
In carrying our Invention into practice, in substitution for the long Deckle frame
generally in use upon a Paper making machine, we provide a short deckle frame a,
preferably of brass and of about 2 feet in length. This frame a, is cast or other-
wise formed with a recess b, of about 10 inches in length so as to receive the Deckle
strap pulley c, and allow it to rotate freely therein. The ends of this deckle
frame a, are made plain, one end is connected to the wooden or transverse portion e,
of the elbow, and the other or opposite end thereof is supported on the bar f, and is
provided with the vertical dovetail groove g. (Figure 1.) wherein the slice herein-
after described, and by which the flow of pulp on the machine is levelled, is free to
be adjusted. The wooden or transverse portion e, of the elbow is connected to the
longitudinal portion thereof in such a manner as to accommodate it to the shake or
vibration of the machine. This may be effected by hinging the two parts of the
elbow together, but we prefer to provide for this vibration, by the elastic con-
struction of the longitudinal portion of the said elbow.-This feature of construction
is represented more particularly on an enlarged scale at Figure 4 of the annexed
drawings, and it consists in arranging the sheet h, of India-rubber or other equivalent
elastic material between the two sheets i, of metal preferably brass. These three
sheets h, and i, respectively are secured by the bolt and nut j, and by the clips k,
and, (Figures 3 and 4) or their equivalents, against the inner side of the deckle
frame a, and the lower edge of the India rubber h, extends down below the brass
plates, at its two sides and bears with more or less pressure as adjusted by the
screw d, upon the apron k', and the breast board l', as hereinafter more particularly
described.
The slice herein before referred to is formed in two parts m, and n, and each of
which parts is provided with a rigid bracket o, and an adjusting screw ?, (Figures 3
and 4) the latter of which bears upon the projection q, (Figures 1 and 2) at the
outside of the deckle frame a, and in this manner supports the said slice. When
the screws p, are turned, the slice rises or falls vertically within its dovetail guides g,
(Figure 1) and thus increases or decreases the thickness of the layer of pulp passing
thereunder. At Figure 1 of the annexed drawings the brackets o, and screws p,
are not represented, for the purpose of enabling the construction of the dovetail
grooves g, and their connections with the portions m, and n, of the slice to be more
clearly understood, and it will be seen with reference to that Figure of drawing
that the said portions m, and n, of the slice are maintained in close contact with
the vertical edge of the sheet h, of India rubber so that the pulp is prevented from
escaping at this part. The two inner ends of the portions m, and n, of the slice
overlap each other and are supported one against the other by means of the clips r,
one of which is secured to each such portion. These clips r, as represented on an
enlarged scale at Figures 5 and 6, are provided, with the vertical screws 8, which
enable the inner ends of the two portions m, and n, to be raised or lowered so that
the layer of pulp may be thicker or thinner at its centre than at its outer edges.
The position of the screws 8, when adjusted may be secured by the lock nuts t, and
the two portions m, and n, bound closely together by the thumb screws u, or their
equivalent.

page_text: Each of the deckle strap pulleys o, is supported and rotates upon a hollow socket
which may be secured to, or, as represented at (Figure 4) it may be formed in
part with, the deckle frame a, and on which it may be retained in position by a
collar or other equivalent means, The deckle frame a, and its attachments at the
opposite side of the machine are constructed in a manner similar to that herein-
before described but the interior surfaces of the sockets v, at the two sides of the
machine are respectively formed with right and left handed screw threads,
Through these sockets v, are screwed the shafts w and x, which are provided with
screw threads respectively corresponding to the screw threads of the sockets v.
The two meeting ends of the shafts w, and x, are united by means of the nut y, in a
manner somewhat analogous to the two parts of a gas-union, that is to say, the end
of one shaft is turned partly conical while the end of the other shaft is turned with
a hollow cone, so that when these two parts are drawn tightly together by the
nut y, they may be rotated together as one shaft. The screwed shafts w, and x,
both extend outwards beyond the deckle frames a, and are supported in and by the
standards z, which are rigidly secured to the side or shake bars a¹, of the machine,
to which bars also are rigidly attached the standards 61, and c¹, for supporting the
shafts d, and e¹, respectively. At the outside of the standards z, and keyed or
otherwise secured to the shafts w, and x, respectively, there are provided the hand
wheels f¹, by means of which the said shafts w, and a, may be rotated together as
one shaft, or when the nut y, has been previously loosened, independently of each
other as herein after explained. At the inside of the standards z, the nuts g¹, are
provided upon the screwed portions of the shafts w, and x, so that by tightening
these nuts g¹, against the said standards z, they act as lock nuts and secure the
shafts w, and x, against rotation. The deckle pulleys h¹, and i¹, are not secured upon
but are free to rotate and slide longitudinally upon their respective shafts d',
and e', so that when the deckle straps j', are moved inwards or outwards these
pulleys all automatically assume their parallel positions. The bar f, hereinbefore
referred to is supported in the standards k³, wherein it is secured against longi-
tudinal motion by the bolts 12, or their equivalents and those ends of the deckle
frames a, which are supported upon the said bar f, are also capable of sliding
longitudinally thereon.
The apron k¹, hereinbefore referred to is composed of india-rubber or other
analogous material and is secured to the breast board 1, by the metal plate m',
between which, and the said breast board 1, it is retained by the screws n', the said
apron under our present Invention being of an increased width extending nearly to
the slice m, n. The breast board 1, is secured to the transverse bar o', of the
shaking or vibrating frame, by means of the brackets p', which are bolted or other-
wise secured to the underside of the said breast board.
The vibrating portion of the mechanism which is hereinbefore described is
connected to the rigid or fixed vat q¹, or breast r¹, of such vat, by means of the
vertical and horizontal sheets a¹, of india-rubber which are secured down upon
these two vibrating and rigid parts respectively by the plates t', and screws u¹.
It will readily be understood from the foregoing description of apparatus that
when the two screwed shafts w, and x, are rigidly united by the nut y, they may
be rotated as one shaft and thus cause the deckle frames a, and their respective
pulleys c, and elbows e, to simultaneously move in opposite directions, that is to
say, to approach toward or recede from one another so that the width of the layer
of pulp passing over or through the machine is correspondingly affected. When
the nut y, has been loosened in the manner hereinbefore referred to, either of the
screwed shafts w, and x, may be rotated independently of the other so that the
width of the layer of pulp may be regulated at one side of the machine only.
When the deckle pulleys h¹, and i, have arrived at their respective positions parallel
with the deckle pulleys c, which generally results after a few revolutions thereof,
the position of the deckle straps j', may be secured against deviation by means of
the rollers w', which are pivoted in the arms x, (Figure 1) and which arms are

page_text: capable of being adjusted within the standards y¹, so that they may be in rolling
contact with the said deckle straps j¹.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
The general arrangement and combination of parts whereby, without necessi-
tating the stoppage of paper making machines, the two deckle frames a, thereof
and their respective pulleys c, and elbows e, and their attachments may be moved
simultaneously nearer to or farther from each other and whereby, after loosening
the coupling nut y, each such deckle frame a, and its attachments may be moved
nearer to, or farther from, but independently of, the opposite deckle frame a,
substantially as and operating in the manner herein before set forth with reference
to the annexed drawings.
