Improvements in Gig Mills Employed in the Finishing of Textile
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,
particularly such Gig Mills as are described in the specification of my patent
No. 11640 year 1885.
DESCRIPTION OF DRAWINGS.
Fig. 1, shows an elevation of Gig Mill with my improvements applied.
Fig. 2 is a front elevation of Fig. 1.
Figs. 3 and 4 are enlarged details of strap fork and indicator.
In patent No. 11640, year 1885 it will be seen that the card rollers a, a, a, are
regulated by straps which surround their pulleys fixed at the ends.
These straps get their motion from the counter shaft c and pulley h, and these are
driven by wheels fg, belts and step cone pulleys e e, driven from the main shaft b,
which runs always at a certain fixed speed. By means of the step cone pulleys e e,
the variation of the speed of the counter-shaft c, is regulated, which again regulates
the variation of the speed of the card rollers a, a, a.
Hitherto I have made these step cone pulleys e e, with five or more steps, the
variation of the speed of the card-rollers a, a, a, could therefore not be less or more
than the effect obtained in shifting the belt from one step to another of these cones.
This has proved to be too great a variation for raising certain classes of goods, and in
order to overcome this difficulty I have made the following improvements.
In the annexed drawings the card rollers a, a, a, are regulated by straps i, which
surround their pulleys fixed at the ends of such rollers; these straps get their motion
from the counter-shaft c, and pulleys h, and these are driven by wheels f, g, and plain
pulley e.
This plain pulley e, is connected by a belt k, with pulley 1, which gets its motion
from the taper cone o, by bevel wheels m, n; the cone o receives its motion by means
of a belt p, from another cone q, driven by the mitre or bevel wheels r, s, and pulley t,
by belting from pulley u on main shaft b. It will be seen that in shifting belt p, on
the taper cones o, 9, the speed of the pulleys 1, e, and through them of the card
rollers a, a, a, may be perfectly and gradually decreased or increased as required
which as stated before, for some goods is of great advantage.
Shaft v, is a screw which by means of a handle w, works the double strap fork ;
this screw may be replaced by a rack or any other suitable movement.
To the strap fork a, is attached a finger z, pointing to a shaft y, which is divided
into half inches and numbered so that the finger always indicates the speed given by
the belt p.
The before described driving arrangement may be fixed in any convenient position
upon the machine, also the nitre or bevel wheels m, n, r, s, may be replaced by
friction wheels, the pulleys e, l, t, u, by chain wheels.
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 Mills, such as protected by patent No. 11640, year 1885, the employment
of taper cones for speeding gradually the counter shafts which drive the card rollers,
substantially as shown and described.

page_text: 2. The general arrangement of the taper cone driving mechanism as and for the
purposes shown and described.
3. The method of indicating the speed of the cones in the manner and for the
purposes.substantially. as shown and described.
