Improvements in or relating to Machines for Drying Paper, Piece
Goods, and the like.
I, JAMES DEMAINE PICKLES, of 92, Greenway Street, Darwen, in the County
of Lancaster, Paper Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The invention relates to improved apparatus for controlling and regulating the
supply of steam to the drying cylinders of paper making or paper drying machines
applicable to machines for drying and calindering piece goods and yarns, and
consists of a combined tension and steam valve operating device whereby the
steam supply and consequent heat of the drying cylinder or cylinders regulated
and adjusted through expansion and contraction (according to humidity) of the
paper, piece goods, or yarns being passed over the drying cylinder or cylinders.
The invention also comprises an anti-friction sling bearing for axes of the tension
device.
Apparatus for purposes aforesaid and according to this invention comprises a
shaft extending across the machine and in front of one of the drying cylinders.
On ends of said shaft is a bell-crank lever; the horizontal arm of one of such
levers has at its outer end a quadrant from which hangs or depends a strap
carrying balance weights, the other arm of the bell-crank is downwards or
pendent shaped and carries one end of a tension and guide roller. The lower
part of the pendant arm of the T shaped lever is attached by a pin or stud to one
end of a horizontal swing bar having two anti-friction bowls or runners, whilst
the outer end of said bar is supported by an adjustable swing rod, and from the
horizontal bar is a chain, cord, or other connection extending over a guide
pulley, and to the arm of the steam supply valve. In connection with the anti-
friction bowls or runners of the horizontal swing bar is an endless strap having
tappet surfaces, a tappet chain, or a peg barrel for purpose hereinafter explained.
The cross shaft first herein referred to is supported or slung in two (preferably
sheet brass) straps from opposite sides of the shaft, one end of each strap being
fast to the shaft, the other ends are secured to a carrier or part of the framing
of the machine, and inasmuch as the said shaft is not required to make more
than a small part of a revolution, the one strap is partly unwound from, whilst
the other is partly wound around the shaft, consequently the latter makes a
partial roll in the slings, and there is no rubbing or frictional contact between
the shaft and its bearings. There is thus provided a nicety of balance and
adjustment of parts.
The action of the apparatus briefly described is as follows:-When the steam
supply in the drying cylinder and the condition of the paper, piece, or yarn,
is normal, the lower arm of the г shaped lever is vertical. On change of
condition expansion or contraction occurs, and there is more or less (as the case
may be) tension on the tension roller, and the vertical arm of the shaped lever
is moved out of plumb, and thereon the horizontal swing bar is moved and

page_text: through its connections with the steam supply valve, the latter is operated so
as to give more or less steam to the drying cylinder according to requirement;
meanwhile the tappet strap, tappet chain, or peg barrel, is steadily moving and
on coming into contact with the runners, bowls, or pegs of the horizontal swing
bar, will move back and set the pendent arm of the shaped lever again at zero,
and the steam supply will for the time being be normal, again to be varied as
soon as the tappet or peg passes the bowls should the condition of the paper,
piece, or yarn, require continued variation from normal supply.

Improvements in or relating to Machines for Drying Paper, Piece
Goods, and the like.
I, JAMES DEMAINE PICKLES, of 92, Greenway Street, Darwen, in the County
of Lancaster, Paper Manufacturer, do hereby declare the nature of this invention
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 improvements in steam cylinder drying machines for
drying paper and piece goods the object being to utilize the contraction or
expansion of the paper or piece to operate or actuate through the movements
of a tension roller mechanism whereby the steam valve may be automatically
controlled so as to give a greater or less steam supply according to requirements.
Such being the nature and object of my said invention the following is a
complete description of same, reference being had to the accompanying drawing
which is a front elevation of part of three steam drying cylinders with my
improvements applied thereto.
According to this invention A, B and C are the drying cylinders and D the
line of paper or piece being dried.
At 1 is a shaft extending across the machine being pivotedly mounted in
brackets 1 in front of the drying cylinder A. On one or both ends of the said
shaft 1 is mounted a bell-crank lever 3; the horizontal arm 4 of one of such
levers 3 has at its outer end a quadrant 5 from which hangs a strap 6 carrying
balance weights 7. The other arm 9 of the bell-crank lever 3 is downward or
pendant and carries near to its upper end a tension or guide roller S extending
across the machine. The lower part of the lever 9 is attached by a pin or
stud 10 to one end of a horizontal swing bar 11 carrying at its other end two
gear wheels 12-13 whilst the outer end of the said bar 11 is supported by an
adjustable swing rod or chain 4. At 15 is a cord or chain one end of which is
wound around the boss of the wheel 24, and after passing over the guide
pulleys 16-17 the end is attached to the fixed point 26. To the pulley 16 is
attached a cord or chain passing over a guide pulley 16* and then connected with
the arm of the steam supply valve 18. At 19 is the boss of the axle 20 of the
cylinder B and in or attached to such boss 19 is a projection or tappet piece 22
preferably made of leather, which projection so long as the position of the gear
wheels 12-13 and the steam supply is normal passes clear of the said
wheels 12-13, but when the steam supply is in excess or below requirements
the tappet 22 acts on one or other of the wheels 12-13 turning the same, and
by means of the worm and worm wheel 23-24 the cord or chain 15 is wound or

page_text: unwound from the boss 25 and thereby the cord or chain 15 opens or closes the
steam valve as required.
So long as the steam supply is normal or what is required, the vertical arm 9
is plumb, but when the tension on the piece D is less through excess of moisture
and a greater supply of steam is required to dry same the arm 9 actuated by
the weight 7 swings out of plumb towards the left hand carrying with it the
swing bar 11 and so the wheel 13 is moved into such a position that the tappet
piece 22 in its revolution comes in contact with said wheel 13 and through the
movement of the worm 23 wheel 24 and cord connections the steam valve is
operated and opened and more steam supplied. If too much steam is supplied
and the paper becomes too dry and contracted the tension applied to the roller
overcomes the weight 7 and moves the lever 9 towards the right hand and the
roller 8 to the position indicated by dotted lines and the swing lever 11 brings
the wheel 12 linable with the tappet 22 and a reverse motion to that above set
out is imparted to the worm and worm wheel 23-24 and the steam supply valve
is more or less closed.
At 27 is a lever attached by joint to the arm 9 and in such lever is a holding
notch 28 by means of which the controlling mechanism may be moved to the
right hand until the steam valve is closed, and the mechanism can be held
in this position by hooking the notch 28 over the stud 26.
The several brackets and bearings 1-26 for carrying the mechanism are fixed
to or form part of the end frame or guards of the machine not shewn in the
drawing.
The projection or tappet piece 22 may consist of one wiper as shewn, or two
or more of such tappets may be employed in order to adjust the inequalities at
less intervals of time than one complete revolution of the boss 19.
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) In machines for purpose aforesaid the combination of a bell-crank 3 carry-
ing the tension roller 8 the pendant arm 9 swing bar 11 carrying the gear
wheels 12-13 and the projection 22 which operates the steam valve as and for
the purpose herein described and substantially as illustrated by the annexed
drawing.
(2) In machines for purpose aforesaid, the combination of the weighted lever 4
quadrant 5 and weight 7 for operating the arms 3 and 9 tension roller 8 arm 11
gear 12-13 worm 23 worm wheel 24 for winding or unwinding the cord con-
nection 15 communicating with the steam valve lever as and for the purpose
herein described and illustrated by the annexed drawing.
(3) In machines for purpose aforesaid the use in combination of the gear
wheels 12-13 operated by a wiper or tappet piece such as 22 said wheels operating
the worm and worm wheel 23-24 and cord connection with the steam valve
lever as herein described and substantially as illustrated by the annexed drawing.
