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 :—
This invention relates to improvements in gig mills employed in finishing woven
fabrics and has for its principal object the construction of an improved machine
arranged in such manner that the cards or teasels can be regulated or adjusted to
operate with more or less power and effect as required according to the thickness and
strength of the cloth under treatment and according to the nature of the finish or nap
to be raised theroon.
We accomplish this object by means of a raising cylinder the surface of which is
.composed of two or more, preferably four, bars or segmental plates covered with teasels
or card clothing. These segmental plates are mounted on discs or spider wheels and
each plate is connected at each end by links or other suitable connections to an
eccentric or equivalent preferably mounted on the boss of a pinion driven by a spur
wheel mounted loose on the cylinder shaft the spur wheels as well as the cylinder
shaft being driven preferably by frictional driving gear substantially in the manner
described in the Specification to Letters Patent No. 7844 A.D. 1887 granted to us
but any other suitable arrangement of driving gear may be employed so long as the
segmental carding plates receive a reciprocating motion preferably concentric with
the axis of the cylinder and independent of the revolving motion they receive around
said axis.
Our present intention is to employ two raising cylinders in each machine with say
four segmental carding plates on each cylinder one cylinder being adjustable with
respect to the other so that the cards may be ground in their places as described in our
Specification No. 1120 A.D. 1888.
The raising cylinders may either both revolve in the same or in the opposite direc-
tion to that in which the cloth is travelling or one cylinder may revolve in the same

page_text: direction and the other in the reverse direction and the card teeth may be set
in the same direction or in the opposite direction to that in which the cloth is
travelling.
When the cylinders are revolving in the same direction as the cloth no raising action
would take place until the independent vibratory motion was given to the segmental
plates by setting on the friction or other gearing to drive the toothed wheels and
eccentrics, then more or less raising would be produced according to the movement
of the carding surfaces on the cloth caused by the eccentrics. When the cylinders
are revolving in the direction opposite to that in which the cloth is travelling and the
eccentrics are actuating the reciprocating plates the maximum raising power of the
mill is developed.
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 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 gig mills employed in finishing woven

Our present intention is to raise employing two raising cylinders in each machine
with say four segmental carding plates on each cylinder one cylinder being adjust-
able with respect to the other so that the cards may be ground in their places as
hereinafter described.
The raising cylinders may either both revolve in the same or in the opposite direc-
tion to that in which the cloth is travelling or one cylinder may revolve in the same
direction and the other in the reverse direction and the card teeth may be set
in the same direction or in the opposite direction to that in which the cloth is
travelling.
When the cylinders are rovolving in the same direction as the cloth no raising
action would take place until the independent vibratory motion was given to the
segmental plates by setting on the friction or other gearing to drive the toothed
wheels and eccentrics then more or less raising would be produced according to the
movement of the carding surfaces on the cloth caused by the eccentrics. When the
cylinders are revolving in the direction opposite to that in which the cloth is travelling
and the eccentrics are actuating the reciprocating plates the maximum raising power
of the mill is developed.
And in order that this invention may be fully understood and readily carried into
effect we will describe the accompanying five Sheets of Drawings reference being
had to the figures and letters marked thereon.
Figure 1 is an end elevation and Fig. 2 a plan with some of the gearing and other
parts removed of a gig mill embodying our improvements. Figs. 3 and 4 are views
of one end of one raising cylinder showing one arrangement of mechanism for
imparting the reciprocating motion to the teasel or card bars or plates Fig. 5 is a
longitudinal sectional elevation of the raising cylinder and its gearing and Fig. 6 is
a similar view to Fig. 3 but showing an alternative arrangement of mechanism for
actuating the teasel or card bars or plates.
Similar letters refer to similar parts throughout the several views.
Referring first to Figs. 1 and 2-a designates the frame of the machine and 6 the
main shaft driven by a pair of fast and loose pulleys 61 6 and on which are also
secured two friction discs or plates c c The friction discs ce transmit motion by a
pair of friction rollers & d' respectively each of which is mounted adjustably on a feather
key on its shaft e or el and is adjusted as required by a screw for .
In the machine shown we have two raising cylinder gg and these are driven from
the friction disc c¹ by means of the roller shaft e¹ and a pair of bevel wheels eno
fixed on the shaft e¹ which gear into a pair of bevel wheel g g fixed one upon each
cylinder shaft. Each raising cylinder y or y¹ consists as best shown in the detail
views Figs. 3, 4, and 5, of two discs h h keyed upon the cylinder shaft and each
disc has four slots cut in it near its periphery these slots being preferably equi-
distant from one another and each boing at right angles to the diameter which bisects
it; but the slots might be slightly curved if desired. In each slot h¹ is fitted a block
or slide which carries the teasel or card bars or plate ; which is secured to the
corresponding block at the other end of the cylinder. Each block i is pivoted
loosely by a studi¹ to one end of an elbow lever which is fulcrumed on a stud k¹
on the disc h and at the other end carries on a stud a roller ³ which rests in the
groove of a seven lift cam each stud being connected to the corresponding stud
on the opposite side of the grooved cam 1 by means of one of a pair of two armed
bosses in m² each of which is mounted loosely upon the cylinder shaft g
Each grooved cam is fixed upon the boss n' of a spur wheel n which is mounted
loose upon the cylinder shaft 93, and each pair of wheels n receives motion from a
pair of spur wheels o (see Fig. 2) fixed one at each end of a shaft o¹ on which is
fixed a bevel wheel o driven by a bevel wheel e fixed on the-shafte which is driven
from the friction plate e by the adjustable friction roller d as already described. As

page_text: the grooved cam revolves it alternately raises and lowers the rollers k, which are
coupled together by the arms of the bosses m m' and so actuates the elbow levers k which
as they rock on their fulcra transmit a reciprocating motion to the blocks i and
tensel or card bars or plates j. It is obvious that the motion of the bars or plates j
may be varied by adjusting the position of the friction roller d and moving it nearer
to or farther from the centre of the friction disc c and in like manner that the speed
of the cylinders g g may be varied by adjusting the position of the friction roller d'
relatively to the centre of the friction disc c'. The fabric y to be raised is introduced
to the machine at X (Fig. 1) and traversed over rollers or guides to the revolving
raising cylinder g where it is operated upon by the reciprocating teasel or card bars
or plates thence to the top of the machine over a roller which is driven as herein-
after described; from the roller the fabric returns to the cylinder g' where it is
again operated upon by the bars or plates; thence under a guide roller p¹ to the
other raising cylinder g over a driven roller r back to the cylinder g under a guide
roller and over a delivery roller p³ which may or may not be weighted according
to the nature of the fabric, the fabric being finally plaited preferably by means of the
usual "plaiting down" box & which receives its reciprocating motion from a crank
on a revolving disc s which is driven by belts from a pulley b³, (see Fig. 1) on the
shaft. The aforesaid guide roller is driven by a belt from a pulley (see Fig. 2)
on the shaft b and the guide roller is driven by a belt from the roller but other
suitable arrangements may be employed for guiding and traversing the fabric
through the machine as for example the fabric might be taken round the raising
cylinders.
For convenience-in grinding the tengols or card teeth we prefer to mount each end
of the raising cylinder in a slide block (see Fig. 1) and these slide blocks t may
be moved by screws t¹ to set the cylinder g¹ close to the cylinder and to put the
bevel wheel into gear with a bevel wheel e (see Fig. 2) on the shaft e¹ to cause
the two cylinders gg to revolve in the same direction. If necessary before setting
the cylinders go together the bars or plates are taken off reversed and secured in
position again on their cylinder so as to have the card teeth set in the same direction
on both cylinders. The shaft o' which carries the two spur wheels o is mounted at
each end in a slide u (see Fig. 1) and before the two raising cylinders have been
moved together it is necessary to turn the screws ' and lower the blocks u and the
shaft of and gears o out of the way.
We have shown and described frictional gearing for imparting the revolving
motion to the raising cylinders g g' and also in conjunction with the grooved
cams and elbow levers for imparting the variable reciprocating motion to the
teasel or card bars or plates ; but we wish it to be clearly understood that these
details may be varied or modified without departing from the nature of our present
invention which consists essentially in a raising cylinder composed of two or more
raising bars or plates having an independent reciprocating motion in addition to a
revolving motion around the axis of said cylinder.
One alternative arrangement for imparting the required reciprocating motion to
the teasel or card bars or plates j is illustrated by Fig. 6.
In this case instead of the grooved cam we employ a spur wheel n² fixed on the
boss. n of the spur wheel n (see Fig. 4). In gear with this wheel n² are four
pinions each of which is mounted on a stud o secured to the cylinder end h; on
the boss of each pinion is also fixed an eccentric which by means of an
eccentric strap and link v³, imparts a rocking motion to the levers which are
fulcrumed on the studs and pivoted to the slide blocks which thus receive the
required reciprocating motion.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is ;-
1. A gig mill having a raising cylinder or each raising cylinder the periphery of
which is composed of two or more segmental teasels or card bars or plates to

page_text: which a
variable reciprocating motion is imparted independently of and in
addition to the revolving motion which said bars or plates receive around the
cylinder axis.
2. The combination with means for imparting a variable revolving motion to
the raising cylinders g g', of means for imparting a variable reciprocating inotion
to the segmental teasel or card bars or plates substantially as and for the purposes
herein described and as shown on the annexed Drawings.
3-Mounting one or more raising cylinders constructed substantially as herein
described in adjustable bearings for the purpose of enabling the cards to be ground
in their places on said cylinders without removing the cylinders from the machine
substantially as herein set forth.
4. The several constructions and combined arrangements of parts embodying our
improvements in gig mills substantially as herein shown and described.
