PROVISIONAL SPECIFICATION.
Improvements appertaining to Carding Machines employed in the
Preparation of Wool and other Fibrous Substances.
We, IRA ICKRINGILL of the Firm of Ira Ickringill and Company Limited of
Keighley in the County of York, Worsted Spinners, and ALFRED SMITH of the
same place, Foreman, do hereby declare the nature of this invention to be as
follows, that is to say :-
In connection with those carding machines wherein a kind of trough or guard of
sheet metal or other material is fixed to intervene between the main cylinder of
said carding machines and the floor for purposes well known, a difficulty has been
experienced in avoiding damages and disarrangement to and of certain of the card
rollers known as workers and strippers by reason of the accumulations of fibres
which on failing to be taken by the "doffer" fall upon the edge of the above
described trough or guard and there remain until sufficiently bulky to be drawn in
by the main cylinder around with which they travel in lumps or burrs causing the
damages and disarrangement referred to, by throwing these workers or strippers
out of their bearings.
To obviate this defect and make the fibres as they fall pass along with the main
cylinder in an even and desirable manner is the object of our invention. This we
attain by mounting a plain roller in suitable proximity with the main cylinder and
" doffer
as also with the edge of the trough. Rotary motion is imparted by chain
and sprocket wheel or other mechanism to this said plain roller the direction of this
motion being so that its upper periphery will travel from the main cylinder by
which means as any fibres fall they are caught by this plain roller and moved to
continue their fall so as to reach the floor.

COMPLETE SPECIFICATION.
Improvements appertaining to Carding Machines employed in the
Preparation of Wool and other Fibrous Substances.
We, IRA ICKRINGILL of the Firm of Ira Ickringill and Company Limited, of
Keighley in the County of York, Worsted Spinners and ALFRED SMITH of the
same place, Foreman, 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, that is to say :-
In connection with those carding machines wherein a kind of trough or guard of
sheet metal or other material is fixed to intervene between the main cylinder or
swift of said carding machines and the floor for purposes well known, a difficulty
has been experienced, in avoiding damages and disarrangements to and of certain
of the card rollers known as workers and strippers by reason of the accumulation
of fibres which, on failing to be taken by the doffer, fall upon the edge of the above
described trough or guard and there remain until they have accumulated into a
sufficient bulk to be drawn in by the main cylinder or swift around with which they
travel in lumps or burrs causing the damages or disarrangements referred to by
throwing these workers or strippers out of their bearings.

page_text: In the accompanying sheets of drawings
Fig. 1 is side elevation of a portion of a carding machine showing the application
of our improvements.
Fig. 2 is a similar view to Fig. 1 but the framework and other parts are omitted
so that our invention may be more clearly understood.
To obviate the defect herein before described and prevent the fibres from accumu-
lating and being carried along with the swift in lumps or burrs is the object of our
invention, and this we attain by mounting a plain or smooth-surfaced roller a in
suitable proximity with the swift or main cylinder b, and "doffer" c as also with
the edge d' of the trough or guard d.
Rotary motion is imparted by the chain e and sprocket wheels fand g (the
wheel being fixed upon the shaft h upon which is fixed the sprocket wheel k, this
wheel being operated by the well known chain m through which motion is
imparted to the other parts of the machine) to this roller a, or other meaus, such as
toothed gearing wheels or the like, might be employed for imparting said motion to
said roller a as will be readily understood.
The roller a is rotated in the direction indicated by the arrow n while the swift bis
rotated in the direction of the arrow p in this manner the upper part of the periphery of
the former (roller a) travels from this swift b, by which means as any fibres fall there-
from at this part they are caught by the plain roller a and made to continue their
fall so as to reach the floor instead of being allowed to accumulate on the edge d¹
of the trough d as above described, thus the possibility of these accumulated fibres
being caught by the cylinder b and carried by it along the trough d (from which
they gather all the stray fibres that may have fallen therein and in such quantities
as to completely displace the workers s) is entirely avoided.
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:-
1. In a carding machine the combination of the swift b, the doffer the trough d
and the roller a this latter being mounted and arranged to operate in the manner
and for the purpose substantially as specified.
.
2. In a carding machine, the combination of the roller a, means for imparting
motion to this roller a, the swift b, the doffer c and the trough d substantially as set
forth and described.
