Improvements in Apparatus for Drawing the Slivers from Gill
Boxes, Combing Machines, and the like.
We, THOMAS HENRY ACKROYD, of Birkenshaw Mills, Birkenshaw, near Leeds, in
the County of York, Spinner and Manufacturer, and ALLAN BROADLEY, of the same
place Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the means of delivery of the
slivor from Gill boxes, Combing machines, and the like, in such a manner that, the
sliver is more effectually passed from the machines into the ordinary cans.
Hitherto some difficulty has been experienced in passing the slivers through the
calender rollers, as there is a tendency of the loose fibres of the sliver in passing
through the said rollers, to wrap round the same; and thus draw from the sliver
some of its bulk, and in time choke the rollers altogether.
The calender rollers may be supported and driven in the usual manner, and below
the said rollers we secure a plate, on which are fixed or formed journals for supporting
the additional rollers, which are geared together, and may be driven by means of a
bolt.
The fibrous sliver on leaving the machine, passes through a hole in the ordinary
guide plate above the rotating calender rollers, the circumferences of which are in
contact with the additional rollers, which revolve in such direction, that any loose
fibre on leaving the calender rollers is conducted along with the sliver into the can
placed below to receive it, instead of the same wrapping round the calender rollers as
is now often the case.

boxes, Combing Machines, and the like.
We, THOMAS HENRY ACKROYD, of Birkenshaw Mills, Birkenshaw, near Leeds, in
the County of York, Spinner and Manufacturer, and ALLAN BROADLEY, of the
same place, Manager, 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 certain improvements in the means of delivery of the
fibrous sliver from Gill-boxes, Combing machines, and the like, and has for its object
the better delivery of the sliver as it is passed from these machines into the
respective sliver cans.
Hitherto some difficulty has been experienced in passing the slivers through the
callender rollers, as there is a tendency of the loose fibres of the sliver in passing
through the said rollers to wrap round the same and thus draw from the sliver somo
of its bulk, and in time to choke the rollers altogether.
We accomplish our object by placing a pair of rotating cloaring rollers below the
ordinary calender rollers, and thus pass the sliver intact and without any possibility
of the loose fibres of the sliver wrapping round the upper or calonder rollers.
By this our arrangemant, we dispense with the ordinary cloth lined "rubbers"
which are liable to great wear and toar involving constant repairs or renewals.
In order that our invention may be understood, we have prepared a sheet of
drawings wherein.
Fig. 1. represents a side viow of our improved apparatus as applied to gill boxes.
Fig. 2. is a plan.
Fig. 3. n front view, and―
Fig. 4. a cross section through the rollers.
The calender rollers A. A. are shown as attached to the delivery end of a gill
box, supported by the usual brackets B. B. secured in the same manner as hitherto.
The calender rollers A. A. may be driven in the usual manner by gearing or by a
belt passing over pulley P. and below the said rollers, we secure a plate D. on which
are fixed the journal blocks E. E. for supporting the additional rollers F. F driven by
a bell on pulley G. the roller spindles being geared together by spar wheels H. H.
The rollers all revolve in the direction of the arrows, and the circumferences of
the respective top and bottom rollers are close together.
The fibrous sliver S. on leaving the rollers R. of the gill box is drawn through the
hole J. in the ordinary guide plate by the revolving calender-rollers A. A. and by
the circumferences of the respective rollers A. and F being close together and
rotating in the direction indicated, any loose fibre from the sliver is conducted along
with the body of the sliver into the can K. placed bolow to receive it, instead of the
same wrapping round the calendor rollers as is now often the case.

page_text: Although the apparatus is shown as applied to a gill box, it will be well understood
by persons skilled in the art of preparing fibrous material for spinning, calender
rollers of the same construction are applied to combing machines for drawing the
slivers therefrom, and that by applying our additional rollers thereto in the manner
described, the slivers will be more effectually conducted into the cans below.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :—
The use of additional or clearing rollers F. F. in combination with the calender or
delivery rollers A. A. of gill boxes, combing machines, and the like, substantially in
the manner and for the purpose herein set forth.
