I, AUGUST MONFORTS, manufacturer, residing in München-Gladbach, Kingdom of
Prussia, do hereby declare the nature of this invention to be as follows:-
My invention relates to gig or teazling-machines in which the cloth is exposed to
the teazling operation at two or more points simultaneously, and its object is to
provide means for imparting different degrees of tension to the different portions of
the cloth operated upon at the same time, and for preventing the teazling-cylinder or
cylinders from drawing the cloth along with them and thereby altering its tension
at any point..
For this purpose I place around the teazling-cylinder or system of cylinders a
number of cloth-conveying rolls and guide-rolls, the conveying-rolls being connected
together by suitable gearing adapted to impart to the rolls equal circumferential speed,
and both sets of rolls being arranged to convey and conduct the cloth at two or more
points across the teazling-cylinder or cylinders. Moreover, the conveying-rolls are
provided on their surface with small pins, hooks or other equivalent devices whereby
the cloth is drawn along and prevented from slipping, and, finally, the driving-
wheels carried by the axles of the conveying-rolls, are so attached to the said axles
that they may be released from the same and fixed again in a different position.
This arrangement allows any one of the rolls to be turned by a certain amount
relatively to its driving-wheel, and the tension of the cloth between the said roll and
the neighbouring rolls to be altered.
Any system of teazling-cylinders rotating with considerable speed, produces an
outward current of air, by which the fibres detached from the cloth are carried about
in the work-room. In order to obviate this inconvenience, I arrange inside of the
system of cylinders a cylindrical case serving as a screen to reduce the strength of the
said current.

Improvements in Gig-machines.
I, AUGUST MONFORTS, manufacturer, residing at München-Gladbach, Kingdom of
Prussia, 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 :-
My invention relates to gig or teazling-machines in which the cloth is exposed to
the teazling operation at two or more points simultaneously, and its object is to
provide means for imparting different degrees of tension to the different portions
of the cloth operated upon at the same time, and for preventing the teazling-cylinder
from drawing the cloth along with it and thereby altering the tension of the cloth at
any point.
For this purpose I place around the teazling-cylinder or the system of rollers
constituting the said cylinder, a number of cloth-conveying rolls and guide-rolls, the
conveying-rolls being connected together by suitable gearing adapted to impart to
the same equal circumferential speed, and both sets of rolls being arranged to convey
and conduct the cloth at two or more points across the teazling-cylinder.
Moreover, the conveying-rolls are provided on their surface with small pins, hooks,
or other equivalent means whereby the cloth is drawn along and prevented from
slipping, and, finally, the driving-wheels carried by the axles of the conveying-
rolls, are so attached to the said axles that they may be released from the same and
fixed again in a different position. This arrangement allows any one of the
conveying-rolls to be turned by a certain amount relatively to its driving-wheel, and
the tension of the cloth between the said roll and the neighbouring rolls to be
altered.
As the system of rollers composing the teazling-cylinder rotates with considerable.
speed, it produces an outward current of air, by which the fibres detached from the
.cloth are carried about in the work-room. In order to obviate this inconvenience,
I arrange inside of the said system of rollers a cylindrical case or drum serving
as a screen to reduce, the strength of the said current.
On the annexed sheet of drawings Fig. 1 shows in transverse section a gig-
machine comprising my improvements. Fig. 2 is a sectional view of a part thereof.
w are the teazling-rollers, carried as usual by means of two disks keyed on the
shaft g, the said rollers being rotated on their own axles in known manner and
simultaneously rotating together with the shaft g. These rollers form together the
teazling-cylinder. The line represents the cloth to be acted upon. Z Z Ze, &c.,
are the cloth-conveying-rolls, and a bbc c¹, &c., the guide-rolls. The latter may,
however, be replaced by fixed bars. To the axles of the conveying-rolls are secured
the sprocket-wheels (shown in Fig. 1 by circles only), over which runs a chain l,
driven in any suitable manner. The conveying-rolls and the wheels k being
respectively of like diameter, the circumferential speed of the former will be the same,
and besides they all turn in the same direction. Instead of the described chain-gear

page_text: the conveying-rolls may be provided with spur-wheels, gearing with intermediate
wheels transmitting motion from one roll to the other in like direction, or any other
suitable mechanism for driving the rolls as required, is employed. The guide-
rolls a bbc, &c., are so arranged relatively to the teazling-cylinder that, between
any two of them belonging to two neighbouring conveying-rolls, for instance,
between the rolls a and b, b and c, &c., the cloth will be brought in contact with
the teazling-cylinder. The conveying-rolls being provided on their surface with pins,
hooks, or other like appliances, as hereinbefore stated, which prevent the cloth from
slipping, it is evident that, when the machine is in operation, the cloth will be drawn
along with uniform speed at all its points of contact with the teazling-cylinder, and
the tension once imparted to the same between any pair of neighbouring conveying-
rolls, is not exposed to variations by the working of the machine even if it should be
very much reduced.
In view of allowing this tension to be altered at will, either upon any portion
between two conveying-rolls or upon the whole extent of the cloth being on its
passage through the machine, the wheels are fitted rotatively upon the bosses p
keyed to the axles of the said rolls (see Fig. 2), and they are arranged to be secured
to the bosses p by means of nuts n working on the ends of the bosses, which have
screw-threads. For facilitating the rotation of these nuts, they may be provided with
hand-wheels. Any one of the said nuts being slackened, the corresponding conveying-
roll may be turned relatively to its wheel k as much as the cloth allows. After the
roll has been adjusted so as to impart to the portion of the cloth being in front of, or
behind the same, the required tension, the nut is screwed tight again. In like
manner the tension of the other portions of the cloth may be regulated to the same, or
to different degrees, as may be desired. If the cloth has to be slackened upon the
whole extent of the part being in the machine, as many of the wheels k are released
at once as may be considered necessary.
The aforesaid cylindrical case or drum serving as screen to reduce the strength of
the outward current of air, produced by the rotation of the teazling cylinder, is shown
in the drawing by the circle m, the said case or drum being fixed to the shaft g by
spiders p or in other convenient manner.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In gig or teazling-machines in which the cloth is brought at one pass two or
more times in contact with the teazling-cylinder, the combination, with the said
cylinder, of a plurality of conveying-rolls Z, Z, Ze, &c., having on their surface pins,
hooks, or other equivalent appliances for preventing the cloth from slipping thereon,
and provided with driving-wheels k, that are secured to the axles of the rolls by
means allowing the rolls to be easily released from, and rotated independently of, the
wheels and connected therewith again, and a mechanism for driving the conveying-
rolls by the wheels k, substantially as and for the purpose specified.
2. The combination, with a teazling-cylinder comprising a set of rollers w, placed
in a circle, of a case or drum m arranged inside of the said set of rollers, substantially
as and for the purpose described.
