Improvements in or relating to Gig Mills Employed in Finishing
Woven Fabrics.
We EDWARD MICHAELIS and ALFRED SMETHURST 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 this Invention to be as follows:-
Our invention relates to gig mills for raising and finishing woven fabrics and
particularly to gig mills of the Grosselin or Moser type in which each raising cylinder
is made up of a series of raising rollers arranged around a common centre and all the
said rollers revolve around this centre in one direction and also are rotated on their
own axes usually in the reverse direction.
Now according to our present Invention we revolve the raising rollers which are
covered with card clothing or wire or other teeth round a common centre as heretofore
but we mount the rollers adjustably in pairs and arrange each alternate pair of rollers
so that the teeth set and act upon the cloth in the direction in which the cylinder and
cloth travel and we arrange the remaining pairs of rollers so that the tooth set and
act upon the cloth in the opposite direction; we rotate all the rollers on their axes in
the reverse direction to the rotation of the main or cylinder shaft at such a speed as
will release the card teeth set in the same direction as the cloth travels allowing them
to act sufficiently on the cloth by their revolution around the main shaft and so that
the card teeth set in the opposite direction to that in which the cloth and cylinder
travel will act against the surface of the cloth effectually.
One object of mounting the raising rollers in adjustable bearings and in pairs is
to enable the rollers in each pair to be set close up to one another and the wire on
one roller ground by contact with the other roller. Instead of mounting all the
rollers in adjustable bearings half of the rollers only or other number may be mounted
in adjustable bearings.
For grinding purposes we propose to disconnect the frictional or ordinary driving
gear and we employ a suitable arrangement of gearing whoreby all the rollers may be
caused to rotate in the opposite direction to that in which their teeth are set.
We prefer to drive the rollers when finishing the fabric by the frictional gearing
described in the Specification to our Letters Patent No. 7844 of 1877.

to be particularly described and ascertained in and by the following statement :-
Our invention relates to gig mills for raising and finishing woven fabrics and

page_text: particularly to gig mills of the Grosselin or Moser type in which each raising
cylinder is made up of a series of raising rollers arranged around a common
centre and all the said rollers revolve around this centre in one direction and also
are rotated on their own axes usually in the reverse direction.
Now according to our present invention we revolve the raising rollers which are

but we mount the rollers adjustably in pairs and arrange each alternate pair of
rollers so that the teeth set and act upon the cloth in the direction in which the
cylinder and cloth travel and we arrange the remaining pairs of rollers so that the
teeth set and act upon the cloth in the opposite direction; we rotate all the rollers
on their axes in the reverse direction to the rotation of the main or cylinder shaft at
such a speed as will release the card teeth set in the same direction as the cloth travels
allowing them to act, sufficiently on the cloth by their revolution around the main
shaft and so that the card teeth set in the opposite direction to that in which the
cloth and cylinder travel will act against the surface of the cloth effectually.
One object of mounting the raising rollers in adjustable bearings and in pairs is
to enable the rollers in each pair to be set close up to one another and the wire on
one roller ground by contact with the other roller. Instead of mounting all the
rollers in adjustable bearings half of the rollers only or other number may be
mounted in adjustable bearings.
For grinding purposes we propose to disconnect the frictional or ordinary driving
gear and we employ a suitable arrangement of gearing whereby all the rollers may
be caused to rotate in the opposite direction to that in which their teeth are set.
We prefer to drive the rollers when finishing the fabric by the frictional gearing
described in the Specification to our Letters Patent No. 7844 of 1887.
And in order that our Invention may be fully understood and readily carried into
effect we will describe the accompanying two Sheets of Drawings reference being
had to the figures and letters marked thereon.

applied and Figs. 2 and 3 are detail views of parts of the same.

the wheels or dises a¹ carrying the adjustable bearings of the raising rollers arranged
in pairs 623 one of each pair of bearings is fitted on a right hand screw thread
and the other on a left hand screw on the same spindle & fitted in lugs a³ on the discs a¹;
when the spindle is turned in one direction it causes the rollers to recede from
each other and when it is turned in the other direction it causes the rollers to
approach so that they may be set close up to one another to grind the wire. On
one end of the driving shaft is fixed a friction plate e which drives the friction
pulley d fitted on the shaft d¹ and the friction pulley e fitted on the shaft e¹
the friction pulleys are moved toward or from the axis of the friction plate
by guides screws and hand wheels or by suitable equivalents to vary the
speed; a bevel wheel d' on the shaft d gears into and drives a bevel wheelf fixed
on the shaft and on this last named shaft is keyed the wheelf which gears into
and drives a wheel g fixed on the boss of the large wheel g¹ loose on the shaft a; the
wheel drives the pinions fixed on the shafts of the raising rollers 6*63 and the
alternate pairs of raising rollers 6262 are driven in the same direction by the bevel
wheel e on the shaft el which gears into a bevel wheel i on the shaft on which is
fixed the wheel which gears into the wheel k fixed on the boss of the large wheel k¹
loose on the shaft a and the wheel k¹ gears into and drives the pinions il fixed on
the shafts of the rollers 66. The Drawing shows the parts in the relative positions.

When the machine is not at work and it is desired to grind the card clothing on the
raising rollers for which purpose we reverse the direction of rotation of the rollers b³ 6*
the friction pulleys d and e are withdrawn from contact with the friction plate c and
the wheel m on a feather key on the shaft f¹ is moved inward so as to gear into and
receive motion from the wheel o on the shaft a; the carrier wheel p on the stud p¹ is
moved inward so as to gear with the wheel r on the shaft i¹ and with the wheel o

page_text: which imparts motion to it the shafts 1 and i transmit motion to the raising
rollers band 6 6 by the gearing already described and cause them all to rotate in
the direction opposite to that in which their teeth are set.
Although we have only shown the raising rollers arranged in pairs in adjustable bearing
so that they may be brought in contact with each other and so that the alternate pairs
are or may be driven in opposite directions for grinding they may be otherwise
arranged for instance every alternate roller may be mounted in adjustable bearings so
that it may be brought in contact with another roller when desired but in all cases
it is necessary or desirable that the rollers which are brought in contact with each other
for grinding should have their teeth set in the same direction and should rotate in the
opposite direction to that in which their teeth are set.
By setting the teeth of each pair of raising rollers in the same direction and by
mounting the raising rollers so that they may be brought into contact with and grind
each other a great saving in time and labour is effected in the grinding of the wire or
teeth.
We are aware of the Specifications of Moser's Patent No. 11640 of 1885 and of
Mewburn's (Grosselin's) Patent No. 5394 of 1888 and we wish it to be understood
that we do not claim anything described and claimed therein.
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. In a gig mill for finishing woven fabrics, the arrangement of the raising
rollers in adjustable bearings and in pairs in combination with means for driving all
said rollers on their axes in the reverse direction to that of the rotation of the main
or cylinder shaft substantially as and for the purposes herein set forth.
2.-Mounting the raising rollers of which the raising cylinder of a gig mill is com-
posed in adjustable bearings so that the wire or teeth on one roller may be brought
into contact with the wire or teeth on an adjacent roller for grinding purposes without
removing said rollers from the machine.
3. The arrangement and application of the gearing herein described and illustrated
or equivalent mechanism whereby some of the adjustable mounted raising rollers of
gig mills may be rotated for grinding purposes in the same and the remainder in
an opposite direction to that in which they are rotated when acting upon the fabric.
4. The construction combination and arrangement of parts embodying our im-
provements in gig mills for finishing woven fabrics substantially as herein shown
and as described.
