PROVISIONAL SPECIFICATION.
Improvements in Carding Engines.
I, JOSEPH MOORHOUSE of Oak Street, Shaw, near Oldham, Mill Manager, do
hereby declare the nature of my said invention to be as follows:-
My invention refers to carding engines and relates to the roller on which the lap
rests and by the friction of which the lap is uncoiled and delivered to the ordinary
feed rollers. At present this roller is made with a smooth or plain surface and
hence the lap is liable to slip and become broken by the pull of the feed rollers.
Now my invention has for its object to prevent slipping and afford a more positive
uncoiling or delivery action, and consists in providing the said roller with a series
of holes or perforations extending over the surface thereof and arranged, by
preference in close proximity to each other. The roller being formed hollow and
of cast iron, the perforations may be formed by casting, drilling or stamping.
In practice I have found that by so perforating the roller the fibre of the lap
sinks into the numerous holes and the edges of such holes afford a grip on the lap
and so serve to effectually uncoil the same.

COMPLETE SPECIFICATION.
Improvements in Carding Engines.
1, JOSEPH MOORHOUSE of 15 Oak Street, Shaw, near Oldham, Mill Manager,
do hereby declare the nature of my said invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention refers to carding engines and relates to the roller on which the lap
rests and by the friction of which the lap is uncoiled and delivered to the feeding in
roller. This roller is usually made with a smooth or plain surface and hence
the lap is liable to slip and become broken under the pull of the feed roller. Now
my invention has for its object to prevent slipping and to afford a more positive
uncoiling or delivery action, and consists in providing the said roller with a series
of holes or perforations extending over the surface thereof and arranged, by
preference in close proximity to each other. By so perforating the roller the fibres
of the lap sink into the numerous holes and the edges of such holes affording a grip
on the lap serve to effectually uncoil the same.
And in order that my said invention shall be the more readily understood and
carried into practical effect I have hereunto annexed a drawing illustrating a
perspective view of so much of the feeding in end of a carding engine, as will serve
to illustrate the application of my improvements.
(A) designates a "lap" of cotton and (B) my improved perforated roller on
which the lap rests and by which it is uncoiled and delivered to the feeding in
roller as aforesaid. The roller is perforated as illustrated, more or less, over its
entire surface the holes being, by preference so spaced that as the roller revolves
one lot of holes come into play with the lap before another lot leave it.
number of holes may be varied according to the delivery required, and the shape
and proportions of the holes may also be varied. In Fig. 2 I shew a roller with
The

page_text: rectangular holes and in Fig. 4 a roller with round holes, but said holes may be
oval, triangular, diamond or other shape as desired.
The roller being made of cast iron and of the usual cross section with thin walls,
the holes may be formed by drilling, stamping, or casting, but I have found drilling
by a multiple drilling machine to be most practical.
The use of a perforated roller enables the lap to be uncoiled to the very end
instead of its having, as heretofore with the plain roller, to be taken off the roller,
uncoiled and allowed to overhang the roller in order to get the required friction to
deliver the lap to its extreme end.
With the use of the plain roller when it ceases to revolve the lap beds itself
upon the roller taking up the curvature thereof at the point of contact as seen in
Fig. 3, thus when the roller is restarted it turns round without moving the lap. In
this way the lap becomes broken at or about the point X owing to the continued
pull of the feeding in roller, thus necessitating the repairing of the broken lap and
causing a waste of material. By means of my improvements the fibres of the lap
sink into the holes and therefore produce a series of points or pegs which the roller
can lay hold of (so to speak) and turn the lap.
Instead of being formed with holes the roller may be formed with numerous
counter-sinkings, or may be covered with a sheet of perforated metal of suitable
thickness.
It will be obvious that my improvements are equally applicable to existing
rollers and may with advantage be applied to other rollers in this and similar
machines requiring to give a more positive delivery of textile substances.
Having thus 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 :-
:-
In carding engines and the like the use and employment of a drum or roller
formed or provided with perforations or their equivalent for uncoiling and
delivering the "lap" substantially as hereinbefore set forth.
