Smethurst and Company of Cable Mills Oldham Road Manchester in the County of
Lancaster Finishers and CHARLES WOOD in the employ of the said firm Millwright do
hereby declare the nature of said Invention for IMPROVEMENTS IN GIG MILLS EMPLOYED

Our invention relates to the Invention for which Letters Patent No. 11640 were
granted to Edward Moser on the 30th day of September A.D. 1885 and consists
chiefly in the use and application of frictional gearing for the purpose of driving the

facilities for adjusting accurately the range of variable speeds required for the
satisfactory working of the machine whereby the cloth can be treated more effectually

A suitable arrangement of frictional mechanism for this purpose is as follows:-The
said countershaft from which each of the raising rollers receives an independent
rotatory motion by pulleys and belts as in Moser's patented arrangement or otherwise
is driven by gearing or otherwise from an upright or other shaft upon a feather key or
equivalent on which is mounted and free to slide a friction roller or disc the boss of
which is supported by means of a friction clip or other convenient means.
feather key or equivalent on the main or cylinder shaft is mounted a friction plate or
disc which is moved along the shaft into or out of gear as required with the friction
roller on the upright shaft by means of a suitable clutch lever or otherwise. The
friction clip or equivalent which supports the friction roller is arranged to be adjusted
by screws or other means in order to move the friction roller nearer to or farther from
the centre of the friction plate or disc and so impart a quicker or slower revolving
motion to the countershaft and the raising rollers driven therefrom.

We, EDWARD MICHAELIS and ALFRED SMETHURST both of the firm of Alfred
Smethurst and Company of Cable Mills Oldham Road Manchester in the County of
Lancaster Finishers and CHARLES WOOD in the employ of the said firm Millwright,
do hereby declare the nature of said Invention for IMPROVEMENTS IN GIG MILLS
EMPLOYED IN FINISHING WOVEN FABRICS, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
"
Our invention relates to the Invention for which Letters Patent No. 11,640 were
granted to Charles Edward Moser on the 30th day of September 1885 and consists
chiefly in the use and application of frictional gearing for the purpose of driving the
raising cylinder "from the countershaft our object being to increase and give
greater facilities for adjusting accurately the range of variable speeds required for the
satisfactory working of the machine whereby the cloth can be treated more effectually
and more or less stretching be given to it as necessary.
A suitablo arrangement of frictional mechanism for this purpose is as follows:-
The said countershaft from which each of the raising rollers receives an independent
rotatory motion by pulleys and belts as in Moser's patented arrangement or otherwise
is driven by gearing or otherwise from an upright or other shaft upon a feather key or
equivalent on which is mounted and free to slide a friction roller or disc the boss of
which is supported by means of a friction clip or other convenient means.
On a
feather key or equivalent on the main or cylinder shaft is mounted a friction plate or
disc which is moved along the shaft into or out of gear as required with the friction
roller on the upright shaft by means of a suitable clutch lever or otherwise. The
friction clip or equivalent which supports the friction roller is arranged to be adjusted
by screws or other means in order to move the friction roller nearer to or farther from
the centre of the friction plate or disc and so impart a quicker or slower revolving
motion to the countershaft and the raising rollers driven therefrom.
And in order that our Invention may be fully understood and readily carried into
effect we will describe the accompanying Drawing reference being had to the letters
marked thereon.
This Drawing represents in end elevation one of Moser's Patented gig mills with a
raising cylinder made up of a series of in this case fourteen raising rollers a each of
which receives an independent rotatory motion in addition to the revolving motion of
the cylinder as a whole: bis the cylinder shaft which is driven by fast and loose
pulleys or by any convenient arrangement of gearing not shown and c is the counter-
shaft from which the raising rollers a receive their individual rotatory motion by means
of the belt d or other means.
The arrangement which we employ to drive the countershaft c according to our
Invention consists of the following parts:-On the countershaft c is keyed the beve!

page_text: wheel e which gears into and receives motion from the bevel wheel fixed
on the vertical shaft f and on a feather key or equivalent on the shaft f is
mounted the friction roller. g the boss of which is grooved and held in a clip h¹
which is supported on a frame consisting of the rods and crossbars h. The rods of the
frame h are mounted in stationary guides i and the frame is capable of adjustment by
means of a screw joperated by a hand wheel j¹. On a feather key or equivalent on
the cylinder shaft b is mounted the friction disc k which is moved along the said shaft
into and out of gear with the friction roller as required by means of the clutch lever /
which is pivoted on the framing at and is operated by means of a screw and
handwheel m.
To drive the countershaft c and so give rotatory motion to the raising rollers a in
addition to the revolving motion which they receive when the cylinder shaft bis
revolving the clutch lever / is operated to slide the friction disc k into contact with the
friction roller g which thus receives motion and as the vertical shaft turns the bevel
wheel thereon drives the bevel wheel e and countershaft c and the belt d transmits
rotatory motion to each of the raising rollers. By operating the handwheel j¹ and
screw the friction roller g can be moved nearer to or farther from the centre of the
friction disc k so as to vary the speed of the countershaft c and to impart any required
rate of speed to the raising rollers a: also by slackening the nuts ² the friction roller g
and clip ¹ can be moved along the rods to the other side of the centre of the disc k
and be there secured in position by tightening the nuts h².
We would have it clearly understood that we do not limit ourselves to the details
herein shown and described as the same may be varied or modified to suit different
requirements without departing from the nature of our Invention which consists
essentially in the use and application of adjustable frictional gearing for the purpose
of driving at varying speeds as required the shaft or axis from which the raising
rollers receive their individual rotatory motion. For example it is obvious that more
than one raising cylinder may be employed and that the raising cylinder or each
raising cylinder may be formed of any number of raising rollers and other means for
driving the said rollers from the countershaft or equivalent may be employed also
that any suitable equivalent for the vertical shaft f the friction clip and adjusting
screw and the clutch lever / may be used.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
1. The use and application of adjustable frictional gearing in combination with the
arrangement of mechanism herein shown and described or any other suitable arrange-
ment for the purpose of imparting individual rotatory motion at the varying speeds
required to the raising rollers forming the raising cylinder or cylinders of a gig mill
for finishing woven fabrics.
2. The construction combination and arrangement of parts embodying our improve-
ments in gig mills employed in finishing woven fabrics substantially as herein shown
and described.
