IMPROVE- MENTS IN PAPER MAKING MACHINES
Year: 1885

page_text: I THOMAS ROWLAND, of Dean Mill, Midgley, in the County of York, Foreman
paper maker, do hereby declare the nature of my said invention for "IMPROVE-
MENTS IN PAPER MAKING MACHINES," to be as follows:-
This invention relates to improved apparatus for adjusting, or decreasing, or
increasing the distance between the "dickles," and the width of the apron according
to the width of paper required, such adjustinent being performed with expedition,
and if necessary, without stopping the machine the screw clamps, screw bosses,
heretofore used being dispensed with.
"
According to this my invention, I support the "dickles on cross shafts, carried
by standards, on the side frames of the machines, and upon the side frames, I also
mount standards, which form bearings, for two horizontal screwed, or worm shafts,
these pass through one of the "dickles" and the outer ends of the two screw shafts
are provided with gear and connected by a side shaft. Above the "dickles" and at
right angles to them is a rack, over which is a cross shaft, and on the latter is a
pinion, gearing with the said rack, and also a drum, to which is attached the inner
end of the apron, the latter covering the said drum; the ends of the cross shaft
above the rack are supported by brackets or arms; connected at their lower ends,
to the "dickle," so that when by the gear first herein referred to, the screw shafts
are caused to revolve, to the right, or to the left, so will the "dickle" through
which the screw shafts work, be drawn further from, or brought nearer to, the
centre of the machine, whilst at the same time the movement of the "dickle
will by the connecting arms, carry forwards the cross shaft, and the pinion thereon,
will impart rotary motion to the said shaft, and by the drum thereon, take up, or
pay the apron evenly and regulary across the apron board, there being a guide,
between the apron board, and the drum, under which the apron passes-One or
both "dickles," may be provided with the adjustable apparatus as above described;
or both "dickles" may be connected by right and left handed screwed shaft.

Improvements in Paper Making Machines.
I THOMAS ROWLAND, of Dean Mill, Midgley, in the County of York, Foreman
Paper Maker, do hereby declare the nature of my said invention for "IMPROVE-
MENTS IN PAPER MAKING MACHINES" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement
This invention relates to improved apparatus for adjusting, or decreasing or
increasing the distance between the "dickle" and the width of the apron according
to the width of paper required such adjustment being performed with expedition
and if necessary without stopping the machine the screw clamps screw bosses
heretofore used being dispensed with.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this specification, in which :-
Fig. 1 is a side elevation of the Machine.
Fig. 2 is a plan view of the same.
According to this my invention I support the "dickles" 1, 2, on cross shafts 3, 4,
carried by standards 5, (as ordinary) on the side frames 6 of the Machine, and upon
the side frames 6 I also mount standards 7, 8, which form bearings 9 for two hori-
zontal screwed or worm shafts 10, 11, these pass through the "dickle" 1 and the
outer ends of the two screw shafts are provided with gear and connected by a side
shaft or cord and pulleys 12-Above the " dickles" and at right angles to them is
a rack 13, over which is a cross shaft 14, and on the latter is a pinion 15 gearing
with the rack 13, and also a drum 16, to which is attached the inner end of the
apron 17, the latter covering the said drum, the ends of the cross shaft 14 above
the rack 13 are supported by brackets or arms 18, connected at their lower ends, to
the dickle" 1.so that when by the gear or cord 12 herein referred to, the screw
shafts 10, 11, are caused to revolve to the right or to the left so will the "dickle."
through which the screw shafts 10, 11 work be drawn further from or brought
nearer to the centre of the Machine, whilst at the same time the movement of the
"dickle" will by the connecting arms 18, 18, carry forwards the cross shaft 14 and
the pinion 15 thereon will impart rotary motion to the said shaft 14, and by the
drum 16 thereon, take up or pay out the apron evenly and regularly across the
apron board 19, there being a guide 20 between the apron board and the drum
under which the apron passes-One or both "dickles" may be provided with the
adjustable apparatus as above described.

page_text: 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
The adjustable dickles, the rack and pinion, drum and apron, in combination
and as herein described and illustrated in the annexed drawings, or any mere
modification of the same.
