AN IMPROVED. METHOD OF AND APPARATUS FOR 'GILLING' WOOL
Year: 1884

page_text: I, WILLIAM TERRELL GARNETT, of the firm of William Garnett & Co, Spinners,
Barkerend Mills, Bradford, in the county of "York, do hereby declare the nature
of the said invention for "AN IMPROVED. METHOD OF AND APPARATUS FOR 'GILLING'
WOOL" to be as follows:—
"
My invention relates to applying a double set of "fallers" to "gill boxes" which
arrangement of "fallers" has hitherto only been applied to "preparing boxes
through which wool or other fibrous substance to be combed is passed before going
through the process of combing.
This improved arrangement of fallers working in what are called "gill boxes "
in distinction to "preparing boxes" is caused to operate upon the wool after it
has undergone the process of carding before the process of combing and also after
that process.
The "fallers" are propelled by revolving screws in the ordinary way, the second
set of fallers being actuated by screws of the same pitch as. the first set but driven
by gearing to revolve at a faster speed than the first set; or the screws propelling
the second set of fallers may be constructed with a quicker pitch than those pro-
pelling the first set, thereby obtaining the desired "draft" between the first and
second set of rollers.
I also find it preferable in certain cases to provide the second set of fallers with
finer teeth and at a closer pitch' than the first set, and also to provide a second
dabbing brush to press the wool more completely into the teeth of the second set
of fallers, which dabbing brush has hitherto being applied only to the first set of
fallers.
By these improvements I combine and perfect in one machine and in one
operation the process of gilling both before and after combing which two processes
have hitherto been effected in both instances in two opérations.
By this double operation I effect a saving of time, or produce a finer result in the
same time.

CUMILLIE DIECIFICATION.
I WILLIAM TERRELL GARNETT of the firm of William Garnett and C° Spinners,
Barkerend Mills, Bradford in the county of York do hereby declare the nature of
my invention for "AN IMPROVED METHOD OF AND APPARATUS FOR GILLING'
WOOL" 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 applying a double set of "fallers" to "gill boxes" which
arrangement of "fallers has hitherto only been applied to preparing boxes" or
apparatus for preparing wool before it goes through the process of carding.
This improved arrangement of fallers working in what are called "gill boxes"
in distinction to " preparing boxes" is caused to operate upon the wool -after it
has undergone the process of carding before the process of combing and also after
that process.
The fallers are propelled by revolving screws in the ordinary way, the second
set of fallers being actuated by screws of the same pitch as the first set, but driven
by gearing to revolve at a faster speed than the first set; or the screws propelling
the second set of fallers may be constructed with a quicker pitch than those pro-
pelling the first set, thereby obtaining the desired "draft" between the first and
second set of fallers.
I also find it preferable in certain cases to provide the second set of fallers with
finer teeth and at a closer pitch than the first set, and also to provide a second
dabbing brush to press the wool more completely into the teeth of, the second set
of fallers, which dabbing brush has hitherto been applied only to the first set of
fallers..
By these improvements I combine and perfect in one machine and in one
operation the process of gilling both before and after combing which two processes
have hitherto been effected in both instances, in two operations.
By this double opération I effect a saving of time, or produce a finer result in the
same time.
In order to enable my improvements to be fully understood I will proceed to
describe the same by reference to the accompanying drawings in which figure 1,
represents a sectional elevation and figure 2, a sectional plan of the apparatus
employed in carrying out my improvements.
The fluted rollers A, supply the first set of fallers C, and the fluted rollers B, draw
off the gilled wool from the second set of fallers D. The first set of fallers C, is
actuated by the revolving screws E, which receive motion by means of gearing
'from the bevil wheels F, and the second set of fallers D is actuated by the
revolving screws G, which receive motion by means of gearing from the bevil
wheels H.
When the fallers have dropped at the ends of the propelling screws, they are
returned to the ends of the screws, from which they started, by bottom screws
revolving in the opposite direction to the top screws. The returned fallers are
lifted up from the bottom screws by cams, at the ends thereof, by means of which
cams the returned fallers are re-placed in their position between the threads of the
top propelling screws.

page_text: The second set of fallers D, is in some cases provided with a greater number of
finer teeth or pins and which teeth or pins are placed more closely together than in
the first set of fallers C.
The second set of fallers is caused to travel more quickly than the first set, in
order to obtain the required draft; and the relative speeds of the two sets of
fallers is regulated by change wheels actuating the bevil wheels driving the
propelling screws.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that I make
no general claim to the construction, arrangement or operation of preparing boxes
with double sets of fallers as herein described but what I claim is
(1) In combination with the apparatus hereinbefore described the method or
process of operating upon the fibres of wool, between the processes of carding and
combing and between the processes of combing and spinning; that is to say at a
more advanced stage in the preparation of wool for spinning than that in which
similar apparatus has hitherto been employed substantially as set forth.
(2) The construction and employment of a second set of fallers in gill boxes,
which fallers have finer or smaller teeth or pins and which are more numerous and
are placed closer together than those employed in the first set of fallers whereby
I am enabled to give a finer finish in one process to the wool being gilled.
