IMPROVEMENTS IN APPARATUS- EMPLOYED IN THE MANUFACTURE OF PAPER
Year: 1876

page_text: LETTERS PATENT to George Holloway, of Chartham, in the County of Kent,
Paper Manufacturer, for the Invention of "IMPROVEMENTS IN APPARATUS-
EMPLOYED IN THE MANUFACTURE OF PAPER."
Sealed the 27th June 1876, and dated the 5th January 1876.
PROVISIONAL SPECIFICATION left by the said George Holloway at the
Office of the Commissioners of Patents, on the 5th January 1876.
GEORGE HOLLOWAY, of Chartham, in the County of Kent, Paper Manufacturer.
"IMPROVEMENTS IN APPARATUS EMPLOYED IN THE MANUFACTURE OF PAPER."
The object of the Invention is to afford increased facility for effecting changes
in the width of the paper during manufacture without necessarily stopping the
paper-making machine.
Paper-making machines as at present arranged have the channels formed for the
widths by side or "deckle" frames, which are moved inwards or outwards for
variations of widths by hand, and are attached to a lip or apron, and this apron is
folded up or extended by hand, as the case may be, at each side, to effect which
the paper machine has to be stopped, thereby causing great loss of time and
material.
"
According to my Invention the two sides or "deckles of the channels are
adjustable to the required widths by sliding on the wire cloth and the "
'apron," and
I retain the "apron" fixed to the feeding trough so as not to be folded up at the
ends thereof, and I support the edge of it so that the sides of the channels or the
"deckles may pass over it and the wire cloth freely and without stopping the
paper-making machine for adjustment during working.
"
"
I work the first "slice" or "gate" upon the apron itself or close to the edge of
the apron before the deckle strap comes in contact with the pulp, which enables me
to command a greater depth of pulp in front of the "gate," so as to better equalize
its flow upon the wire cloth, and both the "slices or "gates" are constructed in
links or parts supported by frames or girders, and I make the links or parts of the
slices adjustable by set screws so as to facilitate correct adjustment for making the
paper uniform in substance.

"IMPROVEMENTS IN APPARATUS EMPLOYED IN THE MANUFACTURE OF PAPER."
The object of the Invention is to afford increased facility for effecting changes in
the width of the paper during manufacture without necessarily stopping the paper-
making machine.
Paper-making machines as at present arranged have the channels formed for the
widths of the paper by side or "deckle" frames, which are moved inwards or out-
wards for variations of widths by hand, and these frames are attached to a lip or

According to my Invention the two sides or "deckles" of the channels are
adjustable to the required widths by sliding on the wire cloth and the " apron,"
and I retain the "apron" fixed to the feeding trough so as not to be folded up at
the ends thereof, and I support the edge of this apron so that the sides of the
channels or the "deckles" may pass over it and the wire cloth freely and without
stopping the paper-making machine for adjustment during working.
"
"
I work the first "slice
or "gate" upon the apron itself, or close to the edge of
the apron, before the "deckle" strap comes in contact with the pulp, which enables
me to command a greater depth of pulp in front of the " gate," so as to better
equalize its flow upon the wire cloth, and both the slices or "gates" are con-
structed in links or parts supported by frames or girders; and I make the links or
parts of the slices adjustable by set screws so as to facilitate correct adjustment for
making the paper uniform in substance.
But that the Invention may be the better understood, I will, by the aid of the
accompanying Drawings, proceed to describe means pursued by me in carrying the
Figure 1 shows by plan view, Figure 2 by side view, and Figure 3 by transverse
section, parts of apparatus employed in the manufacture of paper with my improve-
ments applied thereto. The letters of reference employed apply to each of the
views.
a represents the vat containing the pulp; b, the delivery or feeding trough; and c,
clamps, according to my Invention attached to the feeding trough, between which
one edge of the apron d is held. This apron d projects from between the edges of
these clamps c, as represented by the red lines, with its outer edge resting on the
wire cloth, represented by the blue dotted line f, as that cloth passes up over the
cylinder or breast roll g. The clamps c are held in position by set screws c¹ with
capability for adjustment of extent of apron d to project therefrom.
The "slices" or "gates" h are composed of bars h¹ which are formed in parts,
and are applied with capability of sliding one on another, and of being held in the
desired relation by screw and nut h², or other suitable connections; and these bars h¹
are connected to rods h³, which at their upper ends are formed to receive screw
nuts h, by which they are supported from the plates h³; and these plates ho are
supported with capability of sliding on the stationary bars i, i, and of consequent
adjustment of the "slices ог "gates." The bars i, i, are supported at their ends
by stationary frames j. k represents one of the "deckle" frames, the position of
which is adjustable by screws k¹, k¹, which are formed with necks to revolve in
bearings o, o, and have applied to them the drums or pulleys ; and these pulleys
or drums are connected together so as to be moved simultaneously by bands or
straps and represents one of the deckle straps; m, m, represent the small

deckle frame forming the channel for conducting the pulp from the feeding trough c
on to the wire cloth f.
Having thus described my Invention, and means which I find to answer in
carrying the same into effect, I would have it understood, that I do not confine
myself to the precise arrangements of parts as thus shown and described, as
variations may be made in the same without departing from the peculiar character
of my Invention; but what I claim is,-
First. The arranging or combining parts in connection with apparatus employed
in the manufacture of paper, whereby the feed apron is held as required, and the
sides or "deckles are capable of adjustment without the necessity for stopping the
working of such apparatus, substantially as described.
"
Secondly. I claim the arranging or combining parts whereby the position of the
"slices" or "gates” is adjustable, substantially as described.
In witness whereof, I the said George Holloway, have hereunto set my hand
and seal, this Twenty-sixth day of June, in the year of our Lord One thou-
sand eight hundred and seventy-six.
GEORGE HOLLOWAY. (L.S.)
