We WILLIAM HORSFALL GREENWOOD, Commission Wool Comber, and FREDERICK
FARRAR, Manager both of Upper Castle Street Bradford in the County of York do
hereby declare the nature of our invention for AN IMPROVED APPLIANCE TO
PREVENT THE FORMATION OF LAP ON THE DRAWING OFF ROLLERS OF COMBING
MACHINES to be as follows:-
"
This invention relates to an improved appliance to prevent an accumulation of
fibres or "lap" round the drawing off rollers of combing machines. Hitherto on
the breakage of a sliver the loose end of the sliver continues to be drawn off, and
is liable to wrap round the drawing off roller not covered by the leather or sheet,
thereby forming an accumulation of fibres or "lap" which coming in contact with
the pins of the combing circle greatly damages them.
To carry out our invention we employ a third roller placed against and driven
by the press roller, or roller covered by the leather, or sheet, and in close proximity
to the drawing off roller.. Thus on the breakage of the sliver the loose end of such
sliver is led away by the third roller and is thereby prevented from "lapping" and
coming in contact with the pins of the combing circle.

We WILLIAM HORSFALL GREENWOOD, Commission Wool Comber, and FREDERICK
FARRAR, Manager both of Upper Castle Street, Bradford in the County of York,
do hereby declare the nature of our invention for AN IMPROVED APPLIANCE TO
PREVENT THE FORMATION OF "LAP" ON THE DRAWING OFF ROLLERS OF COMBING
MACHINES 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 novel and useful improvements in the drawing off
rollers of "Nobles" and other combing machines, and its object is to prevent
"lap" or an accumulation of fibres round auch drawing off rollers.
The invention consists of the application to the said drawing off rollers of a
third roller which is placed in such a position relative to such drawing off rollers
that the end of a broken sliver, or any stray fibres, is, or are led away in the
proper direction, and therefore do not lap round the drawing off roller next to the
combing circle which has hitherto frequently occured, and caused serious damage
to the pins of such circle.
In order that those skilled in the art to which our invention appertains may
know how to apply and use the same we will proceed to describe it in detail
referring by letter to the accompanying drawing forming a part of this specification
in which Figure 1 is a sectional elevation of such parts of a combing machine as
are necessary to explain our invention. Figure 2 is a sectional plan of the same,
in which the broken line a, b represents the sectional line of the former figure.
The drawing off rollers A and B have a third roller C, which is preferably
similarly fluted, placed besides them. The roller C is mounted on a vertical stud Ď
fixed on a bracket E secured to any convenient part of the comb frame, and such
roller is placed in contact with the leather or apron F passing round the drawing
off or press roller B, and is therefore made to revolve in the same direction as the
drawing off roller A which it is arranged to just clear; thus, a broken sliver, or
other stray fibres, is, or are led away.in the proper direction by the said third
roller C; therefore such fibres are prevented from lapping round the roller A.
'
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare what
we claim is:
In a combing machine, the combination with the drawing off rollers of a third
roller, substantially as herein shewn and described and for the purpose specified.
