Improvements in Apparatus for Dressing and Finishing Woven
Fabrics.
I, THOMAS THORP, Engineer of 161 Great Clowes Street Broughton,
Manchester, and CHARLES WOOD, Engineer of 76 Romford Street, Heaton
Norris, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to that class of gig mills or apparatus for dressing and
finishing woven fabrics in which a cylinder carrying a series of raising rollers is
caused to revolve while the fabric is caused to travel over the rollers at different
speeds. In these gig mills it is usual to drive the raising rollers at different speeds
by various arrangements of gearing. According to the present invention, only
the cylinder is driven at different speeds, the raising rollers being retarded or held
stationary by friction rings bearing on pullies at their ends, or being driven by
these rings when their cards are ground, sharpened or cleaned.
The fabric is moved by a drawing roller of which the speed is varied by
adjusting a friction roller to bear against various parts of a revolving cone or
disc. The apparatus comprises also a grinding and brushing arrangement for
cleaning the cards, and for laying the pile or nap of the fabric on both sides some
of the brushes or grinders going with the nap, and others going against the nap.
a stud
For driving the cylinder at various speeds relatively to that of the motor shaft,
we employ a driven shaft provided with mitre sun and planet gear of the
following kind. The shaft has fitted on it a set of sleeves each free to turn on
the shaft but each capable of being clamped to it, as, for instance, by a setting
screw. The first sleeve, which is driven by any suitable gear from the motor,
when clamped to the shaft drives it at speed 1. This sleeve has on it a mitre
wheel which operates as the driver of a mitre wheel mounted on
projecting at right angles from a second sleeve. This mitre wheel is carried as
a planet round a stationary mitre sun wheel and therefore the sleeve which
carries the planet, if clamped to the shaft, would drive it at speed . By means
of another set of this sun and planet mitre gear the speed of the shaft may be
reduced to, and so on serially if required. The shaft thus driven by means of
suitable gear drives the cylinder which carries the raising rollers and also drives
the cone or disc by which the speed of travel of the fabric is varied as desired.
Each of the raising rollers has on one end, or on each end, a pulley within a friction
ring which is held stationary or may be driven by chain gear from the motor
shaft. Above the main cylinder is another smaller cylinder carrying card
rollers which can be brought into action on the raising rollers for sharpening
their dents or teeth. Also below the main cylinder is another smaller cylinder
carrying brush rollers for clearing the raising rollers. As the fabric travels
from the machine it passes between two smaller cylinders with toothed rollers,
one of which lays the pile or nap on the one side, and the other lays it on the
other side if desired.
The grinding brushing, and pile laying cylinders are driven by belts or other
suitable gear from the motor shaft.

Improvements in Apparatus for Dressing and Finishing Woven
Fabrics.
We, THOMAS THORP, Engineer of 161 Great Clowes Street, Broughton,
Manchester, and CHARLES WOOD, Engineer, of 76 Bamford Street; Heaton
Norris, 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 that class of gig mills or apparatus for dressing and
finishing woven fabrics in which a cylinder carrying a series of raising rollers is
caused to revolve, while the fabric is caused to travel over the rollers at different
speeds. In these gig mills it is usual to drive the raising rollers at different speeds
by various arrangements of gearing. According to the present invention, only the
cylinder is driven at different speeds the raising rollers being retarded or held
stationary by friction rings bearing on pullies at their ends, or being driven by
these rings when their cards are ground, sharpened, or cleaned; the fabric is
moved by a drawing roller of which the speed is varied by adjusting a friction
roller to bear against various parts of a revolving cone or disc. The apparatus
comprises also a grinding and brushing arrangement for cleaning the cards and for
laying the pile or nap of the fabric on both sides, some of the brushes or grinders
going with the nap and others going against the nap. For driving the cylinder
at various speeds relatively to that of the motor shaft, we employ a driven shaft
provided with mitre sun and planet gear of the following kind. The, shaft has
fitted on it a set of sleeves each free to turn on the shaft but each capable of being
clamped to it, as, for instance, by a setting screw. The first sleeve, which is
driven by any suitable gear from the motor, when clamped to the shaft, drives it
at speed 1. This sleeve has on it a mitre wheel which operates as the driver of a
mitre wheel mounted on a stud projecting at right angles from a second sleeve.
This mitre wheel is carried as a planet round a stationary sun wheel and
therefore the sleeve which carries the planet, if clamped to the shaft, would
drive it at speed . By means of another set of this sun and planet. mitre gear,
the speed of the shaft may be reduced to t, and so on serially if required. The
shaft thus driven by means of a suitable gear drives the cylinder which carries the
raising rollers and also drives the cone or disc by which the speed of the travel of
the fabric is varied as desired. Each of the raising rollers has on one end or on
each end a pulley within a friction ring which is held stationary or may be driven
by chain gear from the motor shaft. Above the main cylinder is another smaller
cylinder carrying card rollers which can be brought into action on the raising rollers
for sharpening their dents or teeth. Also below the main cylinder is another
smaller cylinder carrying brush rollers for cleaning the raising rollers. As the
fabric travels from the machine it passes between two smaller cylinders with
toothed rollers one of which lays the pile or nap on the one side and the other
lays it on the other side if desired. The grinding, brushing and pile laying
cylinders are driven by belts or other suitable gear from the motor shaft.
Fig. 1 of the accompanying drawings is an elevation and Fig. 2 a part plan
showing positive gear for driving the cylinder and pile dressing drums.
Fig. 3 is an elevation and Fig. 4 a part plan showing progressive circumferential
speed driving for the cylinder and pile dressing drums.
Fig. 5 shows an arrangement for driving the machine through compound gearing
by means of setting screws.
Referring to Figs. 1 and 2, A A. are the loose and the driving pulleys driving by

page_text: spur gear A¹ a shaft B upon which are held stationary by hooks when the machine
is raising and driven by setting screws pinching the shaft when grinding, sprocket
wheels B B driving sprocket wheels B* B* which are connected by brackets & to
the friction rings 6' 62. The shaft B by bevil gear C C' drives a balanced sleeve D
which passes through a sun wheel D' held stationary. On stud E of the sleeve D
is a planet wheel E₁ which drives the clutch gear E connected by clutch levers F F
to the next sleeve G and the sun wheel G. Similarly on stud G2 is a planet
wheel H which drives clutch gear H' adjoining clutch H. The shaft I by bevil
gear II drives the cylinder shaft J. Also upon the shaft I is secured a cone K
which transmits through friction roller K' and bevil gears L and L¹ a variable
speed to the cloth roller M. This has a pulley M' driving by a belt the cloth
roller M², a pulley N on the shaft of which drives the cloth roller N¹. The shaft I
by bevel gear P P¹ drives the shaft P' of the pile dressing drum, the discs Q Q of
which carry the dressing rollers 1, 2, 3, 4 with pinions upon one end of each. Two
of these pinions gear with internal gear Q' and the other two with external teeth Q'
which may be held stationary or driven. The shaft P2 by spur gear K R¹ drives
the shaft S of the pile dressing drum the discs S' on which carry the dressing
rollers 5, 6, 7, 8, each having on its one end a pinion; two of these gear with
internal teeth T, the other two with external teeth T', which may be held stationary
or driven. Thus the dressing rollers 1, 2, 3, 4, 5, 6, 7, 8, may have circumferential
speeds relatively to that of the cloth, with the pile and against the pile. The flock
clearing cylinder shaft U has fixed upon it discs U which carry the brush
rollers 1, 2, 3, 4. At the one end of the shaft U is placed internal gear U³, at the
other end external gear U³ which may be held stationary or driven at a speed
relative to that of the raising cylinder. The grinding cylinder shaft V is mounted
in adjustable bearings V' and has secured upon it two discs V2 to carry the card-
clad grinding rollers 1, 2, 3, 4, each having on one end a pinion, two of which gear
with internal teeth W₁ the other two with external teeth W which may be held
stationary or driven at a speed relative to that of the raising cylinder.
Referring now to Figs. 3 and 4 A A are the fast and loose pullies on shaft B on
which is fixed a cone B₁ driving the friction pulley C adjustable along shaft C' by
a screw D and clutch D' worked by a hand wheel D. The shaft C' by bevel
gear E E' drives a friction plate E' fixed on the cylinder shaft F which has loose
upon it internal gear G' and external gear G. To arms of G and G are bolted arms
of chain wheels H and H' which are driven when grinding by chain wheels I I¹
pinched to the shaft by setting screws or are held stationary by hooks when the
machine is raising.
For driving the dressing drums at variable speed J is a roller adjustable along
shaft J by a screw K and fork K' worked by hand wheel K³, the speed of
being thus varied as it is nearer to or further from the centre of E2. The shaft J¹
by bevel gear L L' drives the dressing drum shaft M on which is a
pulley N
driving by a belt a pulley N' on the dressing drum shaft O. This has on the one
end external teeth O¹ on the other end internal teeth O' gearing with pinions upon
the ends of the dressing rollers 1, 2, 3, 4, the external and internal teeth being
held stationary if required.
In the side elevation Fig. 5 A. A are the fast and loose pullies on the shaft B
which by bevil gear C D drives a sleeve carrying a bevil wheel D' gearing with a
planet wheel E which is mounted on stud E¹ of sleeve E2 and revolves around the
sun wheel F. Upon the sleeve E is fixed a wheel G gearing with planet wheel H
which is mounted on stud H' of sleeve H2 and revolves ronud the sun wheel I.
On the sleeve H is fixed a wheel J gearing into planet wheel K mounted loosely
on stud K of sleeve K². L, L1, L2, L³, are setting screws to clamp the several
sleeves. When the screw L is screwed up the shaft N receives the maximum
speed. When L is unscrewed and L' screwed the shaft revolves at half speed and
o on, the cylinder which is driven from the shaft N being thus worked at various
peeds. M M are setting screws which clamp the sun wheels F and I.
