Improvements in Gig Mills Employed in the Finishing of
Woven Fabrics.
I, CHARLES EDWARD MOSER, of Aix-la-Chapelle, Germany, Machine Maker,
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 Gig Mills employed in the finishing of textile fabrics, and
particularly to such Gig Mills as are described in the Specification of my Patent
No. 11,64085.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a side elevation of Gig Mill (as set forth in the Specification of my
Patent No. 11,64085) with my improvements applied.
Fig. 2, is a side view of one part of such Gig Mill, and Fig. 3, is a front view of
same.
Fig. 1. The action of the card rollers a, a, a, is regulated by the straps b, which
surround their pulleys fixed at the ends. The said straps receive their motion from
the countershaft and pulleys A which are driven by wheels E, belts F and step cone
pulleys D driven from the centre shaft B, which runs always at a certain fixed
speed. By means of the step cone pulleys I), the variation of the speed of the
countershaft A is regulated, which again regulates the speed or energy of the card
rollers a, a, a.
'Hitherto I have made these step cone pulleys D with 5 or more steps; the
variation of the degrees of energy of the card rollers could therefore not be less or
more than the effect obtained in shifting belt F from one step to another of these
cones. This has proved to bo too great a variation for raising suitably certain goods,
and in order to overcome this difficulty without altering the present cone pulley
arrangement for driving the countershaft A' I speed the cloth, which is to be raised,
in a perfect gradually progressive manner by means of flat cones d and has shown in
Figs. 2 and 3. of the drawings hereunto annexed.
I
may add that in Gig Mills as set forth in the specification of my Patent
No. 11,64085, and to which my invention particularly refers, the increasing or
decreasing of the speed of the cloth to be raised, has the same result as the
increasing or decreasing of the speed of the card rollers, namely the varying of the
energy of the card rollers; it comes therefore to exactly the same, whether, in order
to obtain a gradually progressive energy of the card rollers, I vary the speed of
the said card rollers, or the speed of the cloth which is to be raised.
Figs. 2 and 3. On the stud C (fixed to the main frame,) revolving loose upon its
stud or shaft is a flat cone d to which is attached a pulley e; this pulley e receives its
motion by a belt from the main shaft B. On frame C is fixed another stud g
carrying a corresponding flat cone / attached to pulley i from which is a belt to
pulley k driving the drawing through roller by means of wheels. On the said
stud g is also a pinion driving a wheel fixed on drawing through roller m.
From cone d to cone runs a belt O which is guided by a double fork q sliding on
a bar p fixed in the main frame.
In sliding this fork q on the bar p, the belt O is shifted along the cones d and h
and their speed varied, and as the two drawing through rollers and m, are in direct
gearing with them, their speed is varied accordingly.
Suppose now that the card rollers a, a, a, of the Gig Mill are working with a
certain speed or energy, but this speed or energy proving to be too strong or too
weak, I can bring the belt O on fat cones d and in such a suitable position that

page_text: any difference of energy of the card rollers between one step to another of step
cones D is obtained simply by speeding the cloth to be raised according to the
degree of energy desired. This is the object of my invention.
Of course the flat cones d and h must be of such form, that they allow any variation
of speed of the cloth. which it is necessary to obtain, in order to arrive at the same
degrees of energy of the card rollers, as if these were driven indirectly by long flat
cones progressing altogether. as much as now the step cones D do from one step
to the next.
On Gig Mills which have step cones of 5 steps, any degree of energy of the cards
may therefore he given between two adjoining steps through the additional flat cones
driving the cloth as described before.
In order to make the cloth adhere firmly to the drawing through rollers, l, m, m,
of the Gig Mill shewn in Fig. 1. I cover them all with perforated sheetings; and
further the cloth is passed behind the Gig Mill between two brush rollers G, G, which
are driven from the main shaft B by straps; these rollers are for the purpose of
cleaning and laying the nap, if required.
At the front of the machine is placed a Heating cylinder around which the
cloth L passes before it goes to the raising cylinder. This "Heating" cylinder H
may either be heated by gas, air, water or steam, its object is to dry and warm the
cloth before it goes on to the card rollers a, a, a; it may be either fixed or
revolving.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In Gig Mills, such as set forth in the Specification of my Patent No. 11,64065,
the employment of flat cones for speeding gradually the cloth which is to be raised
for the purpose as described.
2. The employment of a heating cylinder for the purpose as described.
3. The arrangement of a Gig Mill with two brushes G, G as described and shewn
in Fig. 1.
