Year: 1860

page_text: LETTERS PATENT to Robert Harrison, of Bacup, in the County of
Lancaster, Mechanic, and George Taylor, of the same Place, Carder, for
the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRE-'
Sealed the 22nd May 1861, and dated the 24th November 1860.
PROVISIONAL SPECIFICATION left by the said Robert Harrison, and
George Taylor at the Office of the Commissioners of Patents, with
their Petition, on the 24th November 1860.
We, ROBERT HARRISON, of Bacup, in the County of Lancaster, Mechanic,
and GEORGE TAYLOR, of the same Place, Carder, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
PREPARING COTTON AND OTHER FIBROUS SUBSTANCES FOR SPINNING," to be as
follows:-
Our Invention relates to the "carding engine," and is designed for the
purpose of stopping the delivering rollers which feed the card roller, called the
"licker in" or "breaker," when the said "licker in" stops, so that the cotton
or other fibrous substance may not be fed to the "licker in" and accumu-
late before it when from accidental causes it may happen to be stationary.
The improvement consists in an arrangement of gearing to effect this object
in connection with the driving gearing of the feeding rollers. Upon the

page_text: "licker in card roller we apply a worm wheel gearing with a worm upon a
shaft provided with an arrangement of catch boxes, and also in connection with
the "side shaft" driving the feeding rollers, this "side shaft" is also provided
with "catch boxes," and is so arranged that where the "licker in" stops the
worm shaft stops, and throwing the catch boxes out of gear, which commu-
nicate the driving motion to the feeding rollers, and causes the said rollers to
stop and cease delivering the cotton until the catch boxes are placed in gear
again.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Harrison and George Taylor in the Great Seal
Patent Office on the 22nd May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wo, ROBERT
HARRISON, of Bacup, in the County of Lancaster, Mechanic, and GEORGE
TAYLOR, of the samo Place, Carder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of November, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of
Her reign, did, for IIerself, Her heirs and successors, give and grant unto
us, the said Robert Harrison and George Taylor, Her special license that we,
the said Robert Harrison and George Taylor, our executors, administrators,
and assigns, or such others as we, the said Robert Harrison and George
Taylor, our exccutors, administrators, and assigns, should at any time agreo
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES
FOR SPINNING," upon the condition, amongst others, that we, tho said Robert
Harrison and George Taylor, by an instrument in writing under our hands-
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in tho Great Scal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Robert Harrison and George Taylor,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained-in

page_text: and by the following statement and accompanying Drawings (that is to
say):-
Our Invention relates to the carding engine, and is designed for the purpose"
of stopping the delivering rollers which feed the card rollers called the "licker
in" or "breaker" when the said "licker in "stops, so that the cotton or other
fibrous substance may not be fed to the "licker in," and accumulate before'
it when from accidental causes it may happen to be stationary.
The improvement consists in an arrangement of gearing to effect this' object
in connection with the driving gearing of the feeding rollers. Upon the
"licker in" card roller we apply a worm wheel gearing with a worm upon a
shaft provided with an arrangement of catch boxes, and which is also in connec-
tion with the "side shaft" driving the feeding rollers. This "side shaft" is
also provided with catch boxes, and is so arranged that when the "licker in
stops the worm shaft stops and throws the catch boxes out of gear, which
communicate the driving motion to the feeding rollers, and causes the said
rollers to stop and cease delivering the cotton until the "boxes" are placed
in gear again.
In order that the Invention may be better understood and explained in
detail, we have hereunto attached a Sheet of Drawings, made upon a scale
of about three inches to the foot, and having similar letters of reference marked
upon corresponding parts of the mechanism.
Fig. 1 represents that portion of the carding engine to which the improve-
ments are shewn attached; Fig. 2 is a plan view of the mechanism, and Fig. 3
is also a plan view illustrating a modification or variation of the same; Fig. 4
is a detached view of the spur wheel and ratchet wheel hereafter to be
explained.
In Fig. 1, a, a, is the framing of a portion of the carding engine, and 6,1
the "licker in" shaft, upon which is secured the worm c, gearing with the
worm wheel & upon the vertical shaft c, upon which is the ratchet wheel f
and spur wheel f', the latter rotating loosely, driven by the spur wheel 9 on
the shaft g', which receives its motion, through the catch box k, from the bevil
gearing on the shaft of the feed roller h, the feed roller being driven by the
bevil gearing and side shaft i; upon the shaft g' is placed the "catch box" k,
which acts upon the lever 1, and throws the bevil pinion i on the side shaft
out of gear with the bevil wheel, and so causes the stoppage of the "feed
rollers." Or, if preferred, the mechanism may be caused to act upon the
doffer which drives the side shaft, by stopping which in a similar manner the
same effect is produced, a suitable rod and levers being employed to connect the
catch box or other equivalent on the shaft driving the doffer with the catch
'

page_text: box ; the action of the various parts being as follows:-As long as the "licker
in" continues in action the ratchet wheel f, revolves in the same direction and
at a quickor speed than the spur wheel f', but on the stoppage of the "licker
in," and in consequently of the ratchet wheel, the "pawls" taking hold in the
ratchet wheel stop the revolution of the wheels f' and y; the vertical shaft g'
continuing to rotate causas the lower half of tho catch box to become
depressed, and so acts upon the lever and the rod m as to cause it to
throw tho bovil pinion on tho side shaft out of contact and stop the feed
rollers.
In the modification shewn in Fig. 3 the action is the same, the shaft g!
being dispensed with. The ratchet wheel on the stoppage of the "licker in "
holds the catch box k, which is driven by tho side shaft i, and the wheel g
continuing to revolvo slides on the shaft, and acts on the bell crank lever 1,
thereby throwing the bovil pinion i out of action.
Having now described the nature of the said Invention, together with the
method of performing the same, wo wish it to be distinctly understood that wo
claim stopping the "feeding roller" or "feeding rollers" in carding engines when
the "licker in" card roller stops, by means of the mechanism described and
shown in the Drawings attached, or other modification thereof for effecting tho
desired purpose.
In witness whereof, we, the said Robert Harrison and George Taylor,
have hereunto set our hands and seals, this Twentieth day of May,
in the year of our Lord One thousand eight hundred and sixty-one.
