IMPROVEMENTS IN MACHINES FOR DRESSING OR FINISHING CLOTH
Year: 1884

page_text: I JOHN CLAYTON MEWBURN of 169 Fleet Street in the City of London Fellow
of the Institute of Patent Agents do hereby declare the nature of my invention
for IMPROVEMENTS IN MACHINES FOR DRESSING OR FINISHING CLOTH to be as
"
follows:-
This invention relates to machines for dressing or finishing cloth. The improved
machine comprises as its chief parts a copper steam injector, and 2 drying cylinders
the one of cast iron and the other of copper both heated by steam, in combination
with an endless jacket or apron of felted wool which draws the cloth to be dressed
or finished, and when this jacket or apron lengthens by use, its tension can be
readily regulated by means of a movable roller.
The machine has 2 frames which support all the cylinders and rollers, and
motion is given to it by means of a treadle. On a crank shaft driven by the
treadle is keyed a toothed wheel which by toothed gearing transmits motion to
the
copper drying cylinder. From the shaft of this cylinder motion is transmitted
to the iron drying cylinder. The cloth or fabric to be dressed or finished is wound
on a drum from which it passes over a roller and then over the injector; this has the
form in section of a hollow triangle and is pierced with holes; it is covered with a
thin cloth through which passes the steam for damping the cloth to be dressed. When
the cloth has passed over the injector it enters between the 2 drying cylinders and
then it is drawn onward by the endless felt or jacket. This felt passes round the
iron drying cylinder, then round the copper drying cylinder, then over wooden
rollers placed above the copper cylinder, then over a roller at the back of the
machine, next round the movable tension roller and finally back to the iron drying
cylinder.
The tension roller is movable in a vertical guide so as to be able to tighten the
endless felt or jacket as it lengthens during work. This tension is effected by
means of a transverse shaft which is fitted with a handle and carries a bevel pinion
at each end; these pinions gear with pinions on vertical screws whose nuts serve as
bearings to the tension roller,

page_text: The steam is admitted by valves or cocks and is conducted by pipes to the
drying cylinders, and from one of these cylinders to the injector.
There is a wooden roller which rests upon the iron drying cylinder and can be
lifted when commencing to dress a piece of cloth and also when the dressing is
completed. The part of the machine which carries the iron drying cylinder, the
injector, the roller between the cloth drum and injector, and the cloth drum
can be moved outwards so as to allow of introducing or engaging the cloth
between the 2 drying cylinders and at the same time producing a pressure on
the cloth between them. This pressure is obtained by means of weights attached
to a chain. When it is wished to draw out the movable part, this is effected
by one or more levers fixed to one or more wheels which when the lever is
acted on raise the weights; a catch then takes into a notch in the wheel, and
the movable part can then be drawn out by hand. When on the contrary it
is wished to produce pressure on the cloth the catch is released, and a nose of the
lever bears upon a pin fixed to the movable part and thus presses the iron cylinder
against the copper cylinder.
Cloth in fresh or new pieces can also be dressed by adding to the machine a
roller about 6 or 8 inches from the back roller and of the same diameter and
revolved at the same time by means of a strap which passes over small pulleys
situated outside the frames of the machine on the spindles of these rollers.

page_text: I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow.
of the Institute of Patent Agents do hereby declare the nature of my invention
for "IMPROVEMENTS IN MACHINES FOR DRESSING OR FINISHING CLOTHI and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The improved machine which forms the subject of this invention comprises as
its chief parts a copper injector and 2 drying cylinders the one of cast iron and the
other of copper both heated by steam, and an endless apron of felted wool which
draws the cloth or fabric to be dressed or finished; when this apron lengthens
by, use its tension can be readily regulated by means of a movable roller.
The annexed drawings represent one of the improved machines. Figure 1 is an
elevation of the left hand end, Figure 2 a front elevation of the left band portion
and Figure 3 an elevation of the right hand end. Figure 4 is a plan. Figure 5 is
a horizontal section of the 2 cylinders.
The machine has 2 frames A which support all the cylinders and rollers and
motion is given to it by the pulleys I, I and transmitted therefrom to the various
parts. The pulley shaft carries a disc H which drives the friction roller D, the
shaft of this roller carries an endless screw C which actuates the wheel B; tho
shaft of this wheel carries the copper drying or dressing cylinder O which is
heated by steam. L is a fly wheel to regulate the motion. On the shaft of the
cylinder O is a toothed wheel M in gear with a pinion N on the cast iron drying
cylinder P which is likewise heated by steam. The cylinder P rests on a frame a
which is jointed at o to the main frame and has pressure exerted on it by the
spring b, this pressure being capable of regulation by means of the hand wheel c.
The frame a also carries the drum or roller R which receives the fabric to bo
dressed or finished; the movement of the drum R can be regulated at will by
means of the friction box S. The frame a likewise supports the roller T over
which the fabric to be dressed or finished passes and the pipe Q formed with holes
which constitutes the steam injector. x, x is the endless apron, it travels around
the cylinder O as indicated by the letters U U₁ U U³ and over the rollers
UU U U Us; this apron can be tightened by moving the roller U as far as V
and by lowering the roller U7 as far as X. A roller Y bears on the fabric to bo
dressed or finished; this roller is supported by arms Z, Z at the 2 ends of the
machine; these arms which are mounted on axes at o, o' also carry weighted
levers, which allow of a pressure more or less great being exerted by the
roller Y on the fabric The fabric can be finally received on the roller m.
All the driving mechanism is connected at the left of the machine. A hand
wheel G is fixed on a screw shaft F which in turning in the one direction or the
other moves backwards or forwards a collar E; this collar in turn moves the
roller D on its shaft. The position of this roller relatively to the disc H being
thus adjustable the speed of the machine can be regulated at will. By moving the
handle D' the clutch or guide K can be made to shift the driving belt from the fast
to the loose pulley or vice versa.

page_text: In Figure 3 is seen the arrangement of pipes for heating the cylinders O and P
and the injector Q. The steam is supplied by the pipe f; it enters the cylinder O
at g and leaves it by the pipe i; the inlet of the steam to the cylinder P is effected
by the pipe h; this pipe is fitted with a cock which can be worked by a handle C'
and the connections 1, 1. The steam enters the cylinder P at one end and leaves
it at the other and passes by the pipe t to the injector Q which is fitted with a
cock; the outlet for the steam from the injector Q is at k. The fabric to be
dressed or finished passes from the drum or roller R over the roller T then over
the triangular injector Q which is formed with holes. When it has passed
over the injector the fabric enters between the cylinders O, P from which it is
drawn by the endless apron x. If the fabric is new or in the piece it can be
received on the roller m after the dressing or finishing.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, as communicated to
me, I declare that what I claim is
1. In a dressing or finishing machine, the combination of an injector, 2 drying
or dressing cylinders and an endless apron, arranged and working substantially as
herein before described with reference to the annexed drawings.
2. The combination of parts herein before described and represented in the
annexed drawings and forming an improved dressing or finishing machine.
