IMPROVEMENTS IN APPARATUS FOR FEEDING WOOL, AND OTHER FIBRES TO CARDING ENGINES
Year: 1885

page_text: I, WILLIAM CLIFFE of Perseverance Iron Works, Longwood, near Huddersfield,
Yorkshire, Machine Maker do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR FEEDING WOOL, AND OTHER FIBRES TO CARDING
ENGINES to be as follows :-
"
My invention has reference to prior Letters Patent granted to me bearing date
the 25th day of August A.D. 1884 N° 11,594
In the Specification of such Letters Patent I shewed and described a revolving
brush or winged arms provided with bristles for removing the fibre off the teeth of
a certain roller, and off the teeth of an endless travelling apron which fibre
afterwards dropped into a weighing scale.
According to my present invention I dispense with the rotary winged brush,
and use instead thereof one or more vibrating arms having bristles or card teeth
fixed at their extremities.
I also employ a stationary bar full width of the travelling apron, which bar is
provided with spikes so arranged that when the vibrating brush has passed the
edge of the board, and the points of the teeth in its downward movement for the
purpose of removing the fibre off the endless apron, that in its return movement
the bristles strike the row of the teeth projecting from the board and in so doing
the brush is cleaned and the loose fibres connected thereto are removed, con-
sequently the brush is freed from fibres each time it strikes the endless apron.
The upper vibrating brush cleans the spiked drum in its downward motion and
it is cleaned from loose fibre in its return stroke by coming into contact with the
spike on the endless apron, in exactly the same manner as the lower vibrating
brush is cleaned by the spikes on the stationary bar.
By these means the fibre on the spiked roller, and upon the endless apron is
thoroughly removed with the peculiar advantage of having a clean brush for every
downward stroke.

I, WILLIAM CLIFFE of Perseverance Iron Works Longwood near Huddersfield,
Yorkshire Machine Maker do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR FEEDING WOOL AND OTHER FIBRES TO CARDING
ENGINES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
".
My invention has reference to prior letters Patent granted to me bearing date
the 25th of August A.D. 1884 N° 11,594.
In the Specification of such Letters Patent I shewed and described a revolving
brush or winged arms provided with bristles for removing the fibre off the teeth of
a certain roller, and off the teeth of an endless travelling apron which fibre
afterwards dropped into a weighing scale.
According to my present invention I dispense with the rotary winged brush and
use instead thereof one or more vibrating arms having bristles or card teeth fixed
at their extremities.
I also employ a stationary bar full width of the travelling apron which bar is
provided with spikes so arranged that when the lower vibrating brush has passed
the edge of the board and the points of the teeth in its downward movement for
the purpose of removing the fibre off the endless apron, that in its return movement
the bristles strike the row of teeth projecting from the board, and in so doing the
brush is cleaned and the loose fibres connected thereto are removed, consequently
the brush is freed from fibres each time it strikes the endless apron.
The upper
vibrating brush cleans the spiked drum in its downward motion and it is cleaned
from loose fibre in its return stroke by coming into contact with the spikes on the
endless apron in exactly the same manner as the lower vibrating brush is cleaned
by the spikes on the stationary bar.
In order that my inventions may be more fully understood, reference is herein
made to the accompanying sheet of Drawings illustrative thereof.
Fig. 1 is
sectional elevation of feed box having my improvements and certain other parts
in connection thereto. A the hopper, into which the fibre is placed in the ordinary
manner, and B is the usual spiked lattice sheet employed for lifting the fibre out
of the hopper, as it travels around the rollers C and D. E is the spiked drum or
swift which revolves in the same direction as the rollers C and D so that the teeth
on the swift and lattice sheet revolve in opposite directions at the point of contact
whereby the loose portions of fibre are partly stripped from the lattice sheet Band
carried around by the swift E until they are met by the vibrating brush F which
removes the fibre from the teeth of the said swift and transfers it to the lattice
sheet, from which it is finally removed and thrown into the weighing scale G by a
second vibrating brush H, mounted on the same shaft as the hereinbefore mentioned
brush F. On the return or upward movement of the brush H the bristles come in
contact with the teeth on the stationary bar I which removes any fibre that may
adhere to it whereby it is clean and free from fibres every time it strikes the lattice
'

page_text: sheet. The upper vibrating brush F is also cleaned from loose fibres on its upward
movement by coming into contact with the spikes on the lattice sheet in exactly
the same manner as the lower vibrating brush is cleaned by the spikes on the
stationary bar L. J is the usual vibrating beater or combe employed for removing
the superfluous fibre which the swift or spiked roller E may be carrying around
therewith.
In Fig. 2 I have shewn a modified arrangment of the parts for feeding wool or
other fibres to carding engines, where it will be seen that the swift E and vibrating
brush F are dispensed with the fibre being stripped direct from the lattice sheet B
by the vibrating brush H.
By employing vibrating brushes for purposes explained a great advantage is
found over using a comb or spiked metal bar as the metal comb could not reach
the surface of the spiked swift E and lattice sheet B, but bristles or card clothing
can be used so as to get to the bottom of the teeth on both drum and lattice in
such manner as to scrape or brush the surface of the said swift and lattice sheet by
which means all the fibre can be removed at each stroke, and by cleaning the
brushes first by the teeth on the lattice sheet and by the teeth on the bar I at
each upward movement of the vibrating brushes, a clean brush is presented
each time.
The means and method of giving rotary motion to the rollers C, D, E and
oscillating or vibrating motions to the beater J, and brushes F, and H, are not
shewn and described as they may be various as will be well understood by
machinists.
'
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
Firstly. In combination with the spikes lattice sheet B and spiked swift E of
the vibrating brushes H, and F in manner and for purposes substantially as shewn
and described.
Secondly. The combinating of the spiked cleaning bar I with the spiked lattice
sheet B and vibrating brush H in manner and for purposes substantially as shewn
and described.
Thirdly. The combination of spikes lattice sheet B with the vibrating brush H
substantially as described and shewn.
