PROVISIONAL SPECIFICATION.
Improvements in Carding Engines Used in Carding Flax or other
Fibrous Materials.
We, JAMES MACKIE, of Albert Foundry, Belfast, in the County of Antrim,
Machine Maker, an: GEORGE SILAW, of Florence Terrace, Whiterock Road,
Belfast, in the said county, Works Manager, do hereby declare the nature of this
invention to be as follows:-
-
.:
The object of this invention is to separate the fibre from the wood or other
waste matter before the fibre is deposited on the main carding cylinder.
It consists in the application of an approximately concentric shell or combing
plate placed between a high speed combing roller and the slow speed card feed
roller.
The shell fits closely to the points of the clothing on the high speed combing
roller, and also to the periphery of the feed roller, embracing a portion of the
circumference of the combing roller equal to the approximate length of the fibre
to be combed, and about one fourth the circumference of the feed roller.
The shell may be made with a plain combing surface, or otherwise, as for
instance, spiral grooves may be cut in the surface or perforations cut through
the plate.
In a <
downstriker" card as used for flax we may employ one or more high speed
rollers to strip the combing roller, and place the material upon the main carding
cylinder. In an upstriker" card as used for cotton, these additional rollers,
may not be required.
<<
The feed roller is pressed against the shell by means of levers and weights in
a manner well understood.
•
Immediately below the shell and combing roller is placed an ordinary knife,
or knives fixed and adjusted in the usual manner.
The remaining portion of the combing roller and stripping roller or rollers is
covered by circular covers, plain on the top side, and plain or perforated on
the lower sides.

Improvements in Carding Engines Used in Carding Flax or other
Fibrous Materials.
We, JAMES MACKIE, of Albert Foundry, Belfast, in the County of Antrim,
Machine Maker, and GEORGE SHAW, of Florence Terrace, Whiterock Road,
Belfast, in the said county, Works 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:-
The object of this invention is to separate the fibre from the wood or other
waste matter before the fibre is deposited on the main carding cylinder.

page_text: It consists in the application of an approximately concentric shell or combing
plate placed between a high speed combing roller and the slow speed card feed
roller.
The shell fits closely to the points of the clothing on the high speed combing
roller and also to the periphery of the feed roller embracing a portion of the
circumference of the combing roller equal to the approximate length of the fibre
• to be combed and about one fourth (4) the circumference of the feed roller.
The invention will be fully described with reference to the following drawings,
Fig. 1. Part section of a downstriker card.
Fig. 2. Part section of an upstriker card.
Fig. 3. End elevation of a plain combing plate.
Fig. 4. End elevation of a grooved combing plate.
Fig. 5. Part front elevation of a grooved combing plate.
Fig. 6. Section of a perforated combing plate.
Fig. 7. Part front elevation of a perforated combing plate.
Referring to the drawings.
Fig. 1. A represents part of a main carding cylinder, such as used for carding
flax, and is covered with. carding points in the usual manner. This cylinder
revolves in the direction shown by the arrow; and is termed a downstriker."
B is a slow speed feed roller, and is pressed along line X, Y, against the upper part
of combing plate C, by means of levers and weights in a manner well under-
stood. D is a high speed combing roller, revolving in the direction shown, and
covered with pointed clothing. The combing plate C, fits closely between the
slow speed feed roller B; and the points of the clothing on high speed combing
roller D, as shown. E is a carrier roller, introduced for the purpose of stripping
the combing roller D, and placing, the material upon the main carding cylinder A.
One or more of these carrier rollers E may be used as desired. F. and F, are
knives adjustably fixed under combing roller 1), in the usual manner.
combing plate C is made slightly longer than the length of fibre to be combed.
Fibre is fed up to feed roller B in the usual manner, and is held between feed
roller B and combing plate C, at the point C, until its full length has passed
this point, when it is taken up by the clothing points on rollers D) and E, and
deposited on the main carding cylinder A. During the time the fibre is held
at it is subjected to the combing action of the roller D, and being held up
to the points of the clothing, by the combing plate C, it is effectively stripped of
its waste matter. The loosened waste matter on passing the end of the plate C,
is thrown by the double action of centrifugal force and gravity against the
knives F, and F1, and falls to the ground.
The
The remaining portions of the combing roller D, and stripping roller E, are
covered by means of circular covers H, provided with the usual rods J, and J.
placed at the joints, to prevent undesirable draughts.
Fig. 2, shows the "
upstriker" system in which the cylinder runs in the
direction shown, and in which the roller E. (Fig. 1) is not required.
Fig. 3, shows an enlarged end view of a plain combing plate.
Figs. 4 and 5, show a combing plate provided with spiral grooves G, cut in
the surface as shown, and which give more freedom for the loosened waste
matter to escape.
Figs. 6 and, show a perforated combing plate, and which allows part of the
loosened waste matter to escape through the plate itself.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the said is to be performed, we declare that what
we claim is:-
1. The application to carding engines of a concentric combing plate, substan-
tially as described and illustrated.
2. The combination of a concentric combing plate, a high speed combing roller,
and a slow speed feed roller, substantially as described and illustrated,

page_text: 3. The combination of a concentric combing plate, a high speed combing roller,
a slow speed feed roller, and carrier rollers such as E, substantially as described
and illustrated.
