Year: 1873

page_text: “LETTERS PATENT to Allen Chappell, of Linthwaite, near Huddersfield,
in the County of York, Working Engineer, and John Charlsworth,
of Linthwaite, aforesaid, Carding Engineer, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR FEEDING WOOL OR OTHER FIBROUS
MATERIAL TO CARDING OR OTHER MACHINES OF A LIKE CLASS."
-Sealed the 12th August 1873, and dated the 14th February 1873.
PROVISIONAL SPECIFICATION left by the said Allen Chappell and
John Charlsworth at the Office of the Commissioners of Patents,
with their Petition, on the 14th February 1873.
We, ALLEN CHAPPELL, of Linthwaite, near Huddersfield, in the
County of York, Working Engineer, and JOHN CHARLSWORTH, of
Linthwaite, aforesaid, Carding Engineer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN APPARATUS FOR FEEDING WOOL
OR OTHER FIBROUS MATERIAL TO CARDING OR OTHER MACHINES OF A LIKE CLASS,"
to be as follows:-
This Invention relates to improvements in apparatus for feeding or
supplying wool or other fibrous material to carding engines or machines

page_text: •
of a similar class for which Letters Patent were granted to Philip Charles
Evans and Henry James Hogg King, dated the 20th day of January in
the year of our Lord 1869, No. 184; and the object of this Invention is
to remedy certain defects in such apparatus by providing a simple means
of temporarily suspending the action of the fibre supplying roller, and to
ensure the deposit of fibre on the feed sheet or endless lags at a proper
time, so that there shall be an equal and regular supply of material to
the machine, the apparatus as heretofore constructed by reason of its
irregularity of delivery giving at one time an excess of material at other
times not sufficient,
The motion of the supply roller is temporarily arrested by means of a
forked lever to which a slight oscillatory and rising and falling motion
is imparted by means of a disc wheel operated by a bell crank lever.
When a certain weight of fibre has been delivered by the delivering roller
to the "scale," the latter will tilt slightly, thereby bringing a projection
(attached to the said lever) in contact with a pin of an upright shaft or
bar connected with the gear for driving the supply roller, which gear
is thus put out and the rotation of the supply roller is arrested. Mean-
while the scale is held in its partially tilted position by means of a
catch lever, which lever will be released by a motion or sliding bar
actuated from the driving roller of the feed sheet, and which motion
may be communicated from the said driving roller by means of a shaft
and bevel gearing. It will thus be seen that should the delivering
roller supply the scale more rapidly at one time than another the only
effect will be that the rotation of the said roller will the sooner be
arrested, and that the scale will not as heretofore discharge or deliver
the fibre as soon as filled, but that such delivery will only take place
when the feed sheet has travelled a sufficient distance and a further
sunnly of fibre is necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent 30
filed by the said Allen Chappell and John Charlsworth in the Great
Seal Patent Office on the 14th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALLAN
CHAPPELL, of Linthwaite, near Huddersfield, in the County of York,
Working Engineer, and JOHN CHARLSWORTH, of Linthwaite, aforesaid, 3
Carding Engineer, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Allan Chappell and John Charlsworth, Her
special licence that we, the said Allan Chappell and John Charlsworth,
our executors, administrators, and assigns, or such others as we, the
said Allan Chappell and John Charlsworth, our executors, administrators,
and assigns, should at any time agree 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 APPARATUS FOR
FEEDING WOOL OR OTHER FIBROUS MATERIAL TO CARDING OR OTHER MACHINES OF
▲ LIKE CLASS," upon the condition (amongst others) that we, the said
Allan Chappell and John Charlsworth, our executors or administrators,
by an instrument in writing under our or their, or one of their 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 the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Allan Chappell and John Charls-
worth, 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 and by the following statement and accompanying Sheets
of Drawings, that is to say :-
This Invention relates to improvements in apparatus for feeding or
supplying wool or other fibrous material to carding engines or machines
of a similar class, for which Letters Patent were granted to Philip
Charles Evans and Henry James Hogg King, dated the Twentieth day
of January A.D. 1869, No. 184; and the object of this Invention is to
remedy certain defects in such apparatus by providing a simple means of
temporarily suspending the action of the fibre supplying roller, and to
ensure the deposit of fibre on the feed sheet or endless lags at a proper
time, so that there shall be an equal and regular supply of material
to the machine, the apparatus as heretofore constructed by reason of its

page_text: irregularity of delivery giving at one time an excess of material, and at
other times not sufficient.
The motion of the supply roller is temporarily arrested by means of
a forked lever, to which a slight oscillatory and rising and falling motion
is imparted by means of a disc wheel operated by a bell-crank lever.
When a certain weight of fibre has been delivered by the delivering
roller to the "scale," the latter will tilt slightly, thereby bringing a
projection (attached to the said lever) in contact with a pin on the
"scale" and the fork of the lever against a pin of an upright shaft con-
nected with the gear for driving the supply roller, which gear is thus put
out and the rotation of the supply roller is arrested. Meanwhile the
"scale" is held in its partially tilted position by means of a catch lever,
which lever will be released by the motion of a sliding bar or tappet
actuated from the driving roller of the feed sheet, and which motion
may be communicated to the said driving roller by means of a shaft and
bevel gearing. It will thus be seen that should the delivering roller
supply the "scale" more rapidly at one time than another, the only
effect will be that the rotation of the said roller will the sooner be
arrested, and that the "scale" will not as heretofore discharge or deliver
the fibre as soon as filled, but that such delivery will only take place 1
when the feed sheet has travelled a sufficient distance and a further
supply of fibre is necessary.
Such being the nature and object of this Invention we will now
proceed to describe the same fully, and in order that the same may be
clearly understood we have hereunto annexed two Sheets of Drawings,
and have marked the same with figures and letters of reference, the
same letter referring to the same part in the various views or Figures.

Fig. 1 is a side elevation shewing our apparatus applied to machinery
for the purposes herein set forth. At Fig. 2 is shewn a modification of
that part of the apparatus employed for operating the "stop motion" a
for temporarily arresting the rotation of the supply roller; Fig. 3 is a
detail enlarged view of part of the apparatus.
A is the forked lever to which a slight oscillatory and a rising and
falling motion is imparted by means of the disc B operated by the bell-
crank lever C; D, being a connecting rod actuated by means of the
disc E as usual. When the delivering roller F has delivered to the scale
G a determined weight of fibre the scale will tilt, and the projection H
on the lever A will come in contact with the pin J on the bar of the

page_text: scale lever L, whereon the lever A will be raised, and on the next revo-
lution of the disc B the forked end or foot of the lever will strike the
stop pin S, knocking the same off, and the motion of the supply roller
is arrested by the transfer of the strap from fast to loose pulley as usual.
Meanwhile the scale G is held in its partially tilted position by means
of the catch lever M, which lever will be held in position by means of
the projection N until released by the cam P (on the end of the sheet
roller R) acting on the lever H³.
At Fig. 3 A is a sliding lever actuated by the arm B, the latter
being operated by means of the bell-crank lever C, whereby the said
lever A has a traverse or sliding motion given thereto within the
tube A¹. On the scale G tilting the projection H will by means of the
pin W be raised so that the end of the lever A will strike the pro-
jection H, and so slide or knock off the stop pin S, and the strap is
transferred as usual. The sheet rollers are driven by means of bevel
gear T, T, and connecting shaft Y, so as to secure positive motion for
the sheet.
Having thus fully described the nature and particulars of this our
said Invention, together with the manner in which the same is to be or
may be performed or carried into practical effect, we would have it
understood that what we claim as our Invention is, the construction,
application, and use of apparatus for securing a regular supply of
fibre to carding or other machines of a like class as herein described and
shewn in the Drawings.
In witness whereof, I, the said John Charlsworth, for and on behalf
of myself and the said Allan Chappell, have hereunto set my
hand and seal, this Ninth day of August, in the year of our Lord
One thousand eight hundred and seventy-three.
