MENTS IN APPARATUS FOR THE MANUFACTURE OF PAPER

page_text: I CHARLES JOHN RICHARDSON of Team Valley Paper Mills, Gateshead on Tyne,
Paper Manufacturer do hereby declare the nature of my invention for "IMPROVE
MENTS IN APPARATUS FOR THE MANUFACTURE OF PAPER "
to be as follows:-
The object of the invention is to afford increased facility for affecting changes
in the width of paper during manufacture, without necessarily stopping the paper
making machine."
"
As paper machines are now generally arranged the "deckle frames" which
regulate by their position the width of the paper, are pushed in or drawn out
by hand when an alteration in the width of the paper is required and the "apron
or "lip" which is attached to them has also to be rolled up or spread out, as the
case may be, by hand. This operation can only be carried out well when the
paper machine is at rest, thus involving loss of time and material by a stoppage.
The two deckle frames can also only be dealt with one after the other unless a
double staff of men be used.
According to my Invention the deckle frames are made to move in or out
simultaneously under the manipulation of a single man, without any stoppage of
the paper making machine whilst the action of the same mechanical means rolls
up or spreads out the apron in the required manner.
The deckle frames are carried by two parallel horizontal bars extending across
the machine. These bars are geared together so that they can be turned simul-
taneously by one hand wheel.
By means of right and left hand screw threads upon them the deckle frames are
moved in and out when the bars are turned. The deckle frames carry the wheels on
which the deckle straps run. They also carry horizontal rollers on which the
apron is wound as the deckle frames approach and from which it is unwound as
they recede from each other. A cord and weight in connection with each roller
keeps the apron always strained.

The slices also which regulate the flow of the pulp are connected with the deckle
frames and move in and out with them sliding the one on the other. =

manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-

As paper machines are now generally arranged the "deckle frames" which
regulate by their position the width of the paper are pushed in or drawn out by
hand when an alteration in the width of the paper is required and the "apron" or
"lip" which is attached to them has also to be rolled up or spread out, as the case
may be by hand. This operation can only be carried out well when the paper
machine is at rest, thus involving loss of time and material by a stoppage. The
two deckle frames can also only be dealt with one after the other unless a double
staff of men be used.
According to my invention the deckle frames are made to move in or out
simultaneously under the manipulation of a single man, without any stoppage of
the paper making machine whilst the action of the same mechanical means rolls up
'or spreads out the apron in the required manner.
The deckle frames are carried by two parallel horizontal bars extending across
the machine. These bars are geared together so that they can be turned simul-
taneously by one hand wheel.
By means of right and left hand screw threads upon them the deckle frames are
moved in and out when the bars are turned. The deckle frames carry the wheels
on which the deckle straps run. They also carry horizontal rollers on which the
apron is wound as the deckle frames approach and from which it is unwound as
they recede from each other. A cord and weight or equivalent arrangement in
connection with each roller keeps the apron always strained.
The slices also which regulate the flow of the pulp are connected with the deckle
frames and move in and out with them sliding the one on the other.
In order that my said arrangement may be most fully understood and readily
carried into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a half plan of the deckle frames and other apparatus concerned in
the alteration of the width of the paper.
Figures 2 and 3 are sectional elevations of the same, the sections are taken on
the lines A B and C D in Figure 1 respectively.
a a are two round bars supported in bearings b b on the side frame c of the
paper machine. There are screws on the bars a and the threads of these screws
are right hand on one side of the machine and left hand on the other. d is one
of the deckle frames, there is a similar frame on the other side of the machine.
f

page_text: e is a hand wheel by which the bars a can be simultaneously turned the bars
being geared together by means of chain wheels and an endless chain f. Hence
when the hand wheel is turned the deckle frames (with the parts which they
carry) approach to or recede from each other.
The plate forms a part of the deckle frame and it constitutes one side of the
trough g from which the paper pulp is delivered on to the travelling web of the
machine. H is the deckle wheel it is carried by an axis on the deckle frame and
the endless deckle strap K runs around it.
The width of the paper depends on the position of the deckle straps and is
controlled by them in the usual way. L is a roll carried by brackets fixed to
inner side of the plate d. The ends of the apron M are fixed to the rolls L on either
side of the machine. Each roll L at one end is provided with a small barrel N to
which a cord O is attached; it is lapped around the roll and at its further end it
carries a weight P tending to wind up the apron on the barrel and keep it tight
but nevertheless allowing the apron to unwind from the roll L when the decklę
plates are moved further apart. In place of employing a weight P the cord may
be made fast to the frame of the machine; in this case the barrel N will require to
be coned and suitably proportioned so that equal lengths of apron and cord may be
wound and unwound.
.The slices R R which control the flow of the pulp are jointed together at the
centre so as to admit of their sliding in and out and they are self supporting.
Their ends are received into guide grooves Q in the plates in which they are
adjustable vertically by the thumb screws S.
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 combination of the deckle frames d d which support the deckle
wheels H and the ends of the continuous apron M with the screwed bars a a or
equivalent parts which move the two deckle frames simultaneously in opposite.
directions.
(2.) The combination with the apron M of moveable rollers L and cords and
weights O and P or equivalent parts which keep the apron strained between the
rollers.
(3.) The combination with the deckle frames d of the jointed slices R R.
(4.) The combination of the deckle frames the gear connecting the deckle frames
the apron and mechanism carried upon the deckle frames which spreads and rolls
up the apron substantially as described.
