Year: 1867

page_text: .LETTERS PATENT to Robert King, John Lowden, and William Gartside,
fall of Oldham, in the County of Lancaster, for the Invention of
"CERTAIN IMPROVEMENTS IN CARDING ENGINES."
Sealed the 18th February 1868, and dated the 22nd August, 1867.
PROVISIONAL SPECIFICATION left by the said Robert King, John
Lowden, and William Gartside at the Office of the Commissioners
of Patents, with their Petition, on the 22nd August 1867.
We, ROBERT KING, JOHN LOWDEN, and WILLIAM GARTSIDE, all of Oldham,
in the County of Lancaster, do hereby declare the nature of the said
Invention for "CERTAIN IMPROVEMENTS IN CARDING ENGINES," to be as
follows:
Our Invention is designed for the purpose of stripping and cleaning the
"doffer" cylinder of carding engines, which are machines employed for
preparing and carding fibrous substances, and this cleaning is effected at
regular intervals of time during the continued action of the machine by means
of self-acting mechanism.
The improvements consist in the use of a roller or "stripper" supported
and revolving in the. ordinary grinding roller bearings, and placed over the
longitudinal axis of the "doffer" cylinder; the said roller or stripper is pro-
vided or covered with "cards" over one half its circumference or surface,
which will when revolving in the manner herein-after described enter the

page_text: cards of the doffing cylinder, the remaining balf of the roller being left plain
so as to run clear of the cards on the cylinder. The end of the roller or
stripper shaft is provided with a worm wheel actuated by an arrangement of
gearing which imparts thereto a slow revolving motion, the said worm wheel
being loose upon the shaft, but which drives the "stripping roller" by means
of a catch secured to such wheel taking into a ratchet wheel secured upon the
shaft. Bebind this worm wheel and on the stripping roller shaft a disc one
half of its periphery (corresponding with the half surface of the roller covered
with cards) is secured, being supplied with teeth, and the remaining half being
plain. A small pinion driven by strap and pulley is so situated in connection
with this disc that when the teeth of the disc come into contact with the
pinion the stripper" roller is caused to revolve at an accelerated speed,
and slow during the remaining half when driven by the worm and worm wheel.
The stripper roller is also provided with a comb, which receives a slow
reciprocating motion by means of an eccentric applied to any convenient shaft.
This comb is employed for the purpose of clearing the revolving stripper
during its slow movement of the short loose fibres, cleared from the doffer
cylinder.
66
The action of the machine being as follows:-During the slow motion of
the stripping roller when driven by the worm and worm wheel the reciprocating
comb on the top of the same is employed to cleanse it from all loose short
fibres, which cleansings are received into a trough or receptacle for removal,
and as soon as this clearing of the stripping roller is accomplished the slow
movement of the disc. has brought the teeth upon its-surface into contact with
the revolving pinion simultaneously with the cards, upon the stripper roller
I coming into contact with the cards of the doffer cylinder, which causes the
cards of the stripper roller in revolving to pass through the cards of the doffer
cylinder, causing thereby during such half accelerated revolution a complete
clearance or stripping of the doffer cylinder..
By the employment and use of this peculiar and novel arrangement of
mechanism the necessity of stopping the operation of carding during stripping
is obviated, and the doffing cylinder is kept in a more efficient and constant
working condition, and the fleece delivered being free from short fibres is of a
superior Quality

NOW KNOW YE, that we, the said Robert King, John Lowden, and
William Gartside, do hereby declare the nature of the said Invention, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement and accompanying Drawings
(that is to say)
Our Invention is designed for the purpose of stripping and cleaning the
doffer
cylinder of carding engines, which are machines employed for
preparing and carding fibrous substances, and this cleaning is effected at
regular intervals of time during the continued action of the machine by means
of self-acting mechanism.
The improvements consist in the use of a roller or "stripper" supported
and revolving in the ordinary grinding roller bearings, and placed over the

page_text: longitudinal axis of the "doffer" cylinder. The said roller or stripper is
provided or covered with "cards" over one half or part of its circumference or
surface, which will when revolving in the manner herein-after described enter
the cards of the doffing cylinder, the remaining half of the roller being left
plain so as not to come in contact with the cards on the cylinder. The end
of the roller or stripper" shaft is provided with a ratchet wheel actuated
by a pawl in connection with an arrangement of lever and revolving indented
disc, which imparts thereto a slow revolving motion. Behind this ratchet
wheel and on the stripper roller shaft a disc or wheel is secured, one
half or
segmental portion of its periphery (corresponding with the half or segmental-
surface of the roller covered with cards) being supplied with teeth, and the
remaining surface being plain. A small pinion driven by gearing is so situated
in connection with this disc that when the teeth of the disc come into contact
with the pinion the "stripper" is caused to revolve at an accelerated speed,
and slow during the remaining half when driven by the ratchet wheel and
pawl; the stripper roller is also provided with a comb which receives a slow
reciprocating motion by means of an eccentric applied to any convenient shaft.
This comb is employed for the purpose of clearing the revolving stripper"
during its slow movement of its 'short loose fibres cleared from the doffer
cylinder.
''In order that the Invention may be better understood and explained in
detail we have hereunto attached a Sheet of Drawings made about half size.
Fig. 1 represents a side elevation of that portion of a carding engine sup-
porting the doffing cylinder, to which is applied the "stripping" or "cleansing"
roller for cleansing such doffing cylinder, and the mechanism for actuating
the cleansing roller and comb stripping such 'roller; Fig. 2 represents a side
elevation of the same; and Fig. 3 represents an enlarged view or diagram
of the cards of the stripping roller, shewing their relative position to the cards
of the "doffing cylinder "when passing through the same to cleanse the
doffing cylinder" from short loose fibre whilst the operation is progressing,
the arrows indicating the direction during revolution.
66
In Figs. 1 and 2, a, a, is the "doffing" cylinder, and 6 the stripping roller
supported in the ordinary grinding roller bearings; this stripping roller b is
provided or covered with cards cover half or other portion of its external
surface which enter the cards of the doffing cylinder (as seen in Diagram,
Fig. 3), for the purpose of removing the short loose fibres therefrom; the
remaining surface of the "stripping roller" not covered with cards is left plain
in order that when revolving it will not be in contact with the cards of the
doffing cylinder." The mechanism for actuating the "stripping roller" is

page_text: so arranged as to impart a slow revolution when not in contact with the doffing
cylinder, and a quick or accelerated revolution when stripping or cleansing
the doffing cylinder; and we would remark that a variable revolution for this.
purpose may be effected by several means which are mechanical equivalents,
Cone being described in our Provisional Specification, of which the one here
described is a simplified modification and equivalent, certain parts having been
substituted for others for simplification, the principal-features remaining the
same; and we therefore now describe the simplified arrangement.
'On the end of the shaft of the stripping roller & the, ratchet wheel dis

of the lever f and the revolving indented disc ga slow motion to the stripping.
roller b, whilst the stripping cards care not in contact with the doffing":
cylinder a ; and in order to impart an accelerated revolution to the "stripper,"
or when these cards are in contact, the following mechanism is applied:On
the shaft of the "stripper" roller b, between the ratchet wheel d and the end
of the roller, a partly toothed wheel h is secured, which is supplied with teeth.
on that portion of its periphery corresponding to the covered surface of, the
stripper roller. ; this disc or wheel revolves slowly with the roller when
driven by the ratchet, but when the stripper cards c come into contact with
the cards of the doffer cylinder the continued action of the ratchet brings the.
teeth of, the wheel h into gear with the pinion i, which receives its motion
through the carrier wheel k from the wheel lon the doffer shaft, and the speed
of the pinion when driving the "stripping roller "b is regulated so as to
complete the accelerated revolution of such roller during one revolution of the
doffer cylinder, thus enabling the "stripping cards" c to collect the accumu-
lation of loose short fibre from the doffer cylinder at certain intervals during
the process. of carding. A slow reciprocating motion is imparted to the comb m
by the eccentric n during the slow revolution of the stripping roller, such
comb cleansing the cards c on the revolving stripper 6 from the loose short
fibres and dirt collected from the "doffer" cylinder, and these cleansings are
received into a trough or receptacle for removal, or if preferred this cleaning
conib may be constantly revolving instead of reciprocating; as soon as this
clearing of the stripping roller is accomplished the slow movement of the
disc has brought the teeth upon its surface again into. contact with the
3 revolving pinion simultaneously with the cards upon the stripper roller coming
into contact with the cards of the doffer cylinder, which causes the cards of
the stripper roller in revolving to pass through the cards of the doffer cylinder,
causing thereby during such accelerated revolution a complete clearance or
stripping" of the doffer cylinder.

page_text: By the employment and use of this peculiar and novel arrangement of
mechanism the necessity of stopping the operation of carding during stripping
is obviated, and the doffing, cylinder is kept in a more efficient and constant
working condition, and the fleece delivered being free from short fibre is of a
superior quality.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim,-
First. The novel application and use of a roller or rollers partly covered with
cards employed to "strip" or clean the doffing cylinder in carding engines,
and having an intermittent slow and accelerated revolution effected by the
aforesaid means or other mechanical equivalent, and also the combination
therewith of a reciprocating or constantly revolving comb to clean the said
partly covered stripping roller.
"
Secondly. The novel arrangement of "cards" on cleaning rollers, as shewn
in Fig. 3, whereby the teeth or "cards.". enter the "card" surface to be
stripped whilst moving in the same direction as such surface, but at a reduced
speed, instead of the teeth being opposed and moving in reverse directions as
hitherto, as herein-before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, we, the said Robert King, John Lowden, and
William Gartside, have hereunto set our hands and seals, this
Nineteenth day of February, in the year of our Lord One thousand
…” eight hundred and sixty-eight
