Improvements in Apparatus for the Manufacture of Paper.
We, DANIEL MACNEILL WATSON, Dalmarnock Paper Mills, Glasgow, in the County
of Lanark, Manager, and THOMAS TEMPLETON MACKIE LUMSDEN of the firm of James
Milne and Son, Abbeyhill, Edinburgh, in the County of Midlothian, Engineer, do
hereby declare the nature of this invention to be as follows:-
of
This Invention has for its object improvements in apparatus used in the manufacture
paper and it relates to the deckle frames and straps which by their position regulate
the width of the paper being made the improved apparatus affording facility for
effecting changes in the width without the necessity of stopping the machine.
As constructed in accordance with this Invention the improved apparatus consists of
two fixed standards or brackets between which there extends a horizontal rod or bar
whereon the "deckle" frames are hung or supported. Through a boas on each of
the said frames (and whereon the "decklo" strap pulleys are carried) a screw passes,
the screws, which are threaded in opposite directions, being laid parallel to the
horizontal rod or bar and connected together at their meeting ends by any suitable
clutch inechanism. The bearings in the standards or brackets for the bar or rod and
for the screws are connected together by vertical screws or equivalent means so that
they can be raised and lowered simultaneously.

On cach deckle frame a rod or roller is carried in brackets and over the said
rods or rollers the ends of the "apron' are passed each end having one extremity
of a cord connected to it the cord thence passing to the other side of the machine
where it is conducted over a pulley centred on the bracket or standard. A weight
is hung on the free end of each cord so that in adjusting the width between the
"decklo" frames, and which is effected through turning a hand wheel on the end
of the screw, the width of the "apron is simultaneously adjusted the weights
always maintaining the apron in a stented condition. By making the screw in two
lengths and disengaging the clutch between them the "deckle" frame at one side
of the machine can be shifted without affecting the position of the frame at the other
side.
"
On a plain part of the screw and on the horizontal bar above it a bracket is
carried the said bracket having a horizontal arm with a slotted hole at its outer
extremity through which passes the stem of an eye or jaw which is fixed at the
desired position in the slot by nuts or equivalent means. The inner "slices" for
regulating the flow of the pulp and which at their outer extremities are connected
to the "aeckle" frames pass each other in the said eye or jaw wherein they are
held by a pin which passes through the jaw and through slotted holes made in the
"slices."
"The outer " slices may be similarly carried at their central parts in a
bracket arm or their said parts may be supported from the breast beam in an adjustable
eye or jaw.

page_text: performed, to be particularly described and ascertained in and by the following
statement :-
This Invention has for its object improvements in apparatus used in the manufacture
of paper and it relates to the deckle frames and straps which by their position regulate
the width of the paper being made the improved apparatus affording facility for
effecting changes in the width without the necessity of stopping the machine.
"
The invention is illustrated in longitudinal section at figure 1 in plan at figure 2
in end elevation at figure 3 and in transverse section at ligure 4 of the annexed
drawings and as shown by these figures the improved apparatus consists of two
fixed standards or brackets A, between which there extends a horizontal rod or
bar B, whereon the "deckle frames C, are bung or supported. Through a boss Bi
on each of the said frames (and whereon the "deckle strap pulleys D, are carried
loosely) a screw slnft E, asses, the shaft, which has its ends threaded in opposite
directions, being laid parallel to the horizontal rod or bar B. Instead of one
shaft E, two serows may be employed, their meeting ends being connected by any
suitable clutch mechanism. The bearings in the standards or brackets A, for the
bar or rod B, and for the screw or screws E. are connected together by vertical
screws, or equivalent means so that they can be raised and lowered simultaneously.
On the lower part of each deckle frame (, a bar G, is carried and over the said
bars, the ends of the "apron" H are passed each end having one extremity of a cord I
connected to it, the cord thence passing to the other side of the machine where it is
conducted over a pulley J centred on an arm K projecting from the bracket or
standard A. A weight is hung on the free end of each cord so that in adjusting
the width between the deckle frames C (and which is affected through turning a hand
wheel M on the end of the screw E,) the width of the "apron" is simultaneously
adjusted the weights always maintaining the apron in a stented condition. By making
the screw E, in two lengths and disengaging the clutch between them the deckle
frame at one side of the machine can he shifted without affecting the position of the
frame at the other side.
On a plain part E', of the screw E, and on the horizontal bar B, above it
a bracket N, is carried said bracket having as seen more particularly at figure 5,
horizontal arms N₁, on which jaws Q, are being the said jaws being fixed at the
desired position on the arms by pinching screws or equivalent means. The
"slices "R, S, for regulating the flow of the pulp and which at their outer extremities are
connected to or supported on the "deckle" frames C, pass each other at their inner
onds in the said jaws. The outer "slices" S, instead of having their inner ends so
carried may have the said parts supported from the breast beam in an adjustable eye
or jaw.
་་
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what wo
claim is :-
1. In apparatus for the manufacture of paper a deckle frame and apron arranged
to effect changes in the width of the paper being madu without stopping the machine,
substantially as set forth with reference to the drawings annexed.
2. In apparatus of the class set forth the combination of the rod B screw or
screws E and frames C carrying the deckle strap pulleys D whereby the width of
paper being made can be adjusted without stopping tho machine substantially as
described with reference to the accompanying drawings.
3. In apparatus of the class set forth the combination of the weighted cords I with
the apron and bars G of the frames C whereby the width of the apron is adjusted
simultaneously with the width between the frames and without stopping the action
of the machine substantially as described with reference to the drawings annexed.
