IMPROVEMENTS IN ENGINES FOR CARDING COTTON AND OTHER. FIBROUS MATERIALS
Year: 1862

page_text: LETTERS PATENT to Alfred Travis, Foreman, and Benjamin Travis.
Mechanic, both of Dukinfield, in the County of Chester, for the
Invention of "IMPROVEMENTS IN ENGINES FOR CARDING COTTON AND OTHER.
FIBROUS MATERIALS."
Sealed the 24th October 1862, and dated the 30th April 1862.
PROVISIONAL SPECIFICATION left by the said Alfred Travis and
Benjamin Travis, at the Office of the Commissioners of Patents
with their Petition, on the 30th April 1862.
We, ALFRED TRAVIS, Foreman, and. BENJAMIN TRAVIS, Mechanic, both of
Dukinfield, in the County of Chester, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN ENGINES FOR CARDING COTTON AND OTHER
FIBROUS MATERIALS," to be as follows:-
Our Invention relates to new combination and arrangement of
mechanism for giving motion to the comb, which strips the fibrous material
from the "doffer" of carding engines, and it consists in an excentric or crank
pin fixed in, on, or formed upon a pulley which is free to rotate upon a stud
fixed in a bracket from the framing of the engine. This pulley is driven by a
belt or band from the axis of the main card cylinder, or any other convenient
rotating part of the engine. The excentric or crank pin is arranged to work
in a slot or space formed lengthways in an arm or lever secured to the

page_text: end of the shaft passing in front of the "doffer," which shaft carries the doffer
comb.
The stud upon which the pulley, excentric, or crank is placed is adjustable,
so that it can be brought nearer to or further from the comb shaft, and thus
the oscillatory movements produced by the rotation of the excentric or crank
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Travis and Benjamin Travis in the Great Seal Patent
Office on the 29th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALFRED
TRAVIS, Foreman, and BENJAMIN TRAVIS, Mechanic, both of Dukinfield, in the
County of Chester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Alfred Travis and Benjamin Travis Her special license that we,
the said Alfred Travis and Benjamin Travis, our executors, administrators,
and assigns, or such others as we, the said Alfred Travis and Benjamin
Travis, 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
ENGINES FOR CARDING COTTON AND OTHER FIBROUS MATERIALS," upon the condition
(amongst others) that we, the said Alfred Travis and Benjamin Travis,
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 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 Alfred Travis and Benjamin Travis
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 Drawings (that is to
say):-
Our Invention relates to
a
new combination and arrangement of

page_text: mechanism for giving motion to the comb, which strips the fibrous material
from the "doffer" of carding engines, and it consists in an excentric or crank
pin fixed in or formed upon a pulley which is free to rotate upon a stud fixed
in a bracket from the framing of the engine. This pulley is driven by a belt:
or band from the axis of the main card, cylinder, or any other convenient rota-
ting part of the engine. The excentric or crank pin is arranged to work in: a.
space formed lengthways in an arm or lever secured to the end of the shaft
passing in front of the doffer, which shaft carries the doffer comb. The stud
upon which the pulley, excentric, or crank is placed is adjustable, so that it
can be brought nearer to or further from the comb shaft, and thus the
oscillatory movements produced by the rotation of the excentric or crank can
be made of greater or lesser extent, as required.
Fig. 1 is a side or end elevation, and Fig. 2 a plan view of the mechanism
constituting our Invention, and also so much of a carding engine as is neces-
sary for showing its application; Fig. 3 is a side view with the pulley part
removed, and Fig. 4 a front or edge view, partly in section, of the mechanism
of our Invention detached and drawn to a scale of half its natural size.
A, framing of engine; B, doffer; C, axis of main card cylinder; D, pulley
for tightening the strap driving the "clearers" in carding engines where
"clearers" are used. The doffer comb a is rivetted on arms a¹ adjustable in
length, which are carried by the oscillating shaft 6, having bearings which are
carried by, and can slide in the stands c, secured to the framing. The bear-
ings of the shaft bare adjustable to and from the doffer by the set screws d.
Upon one end of the shaft 6 an arm e is secured, and this arm has two screw
pins frivetted into it upon which a bar e' is secured by adjusting screws.
In
the
space between the bar e¹ and arm e the excentric (g) works against a strip
of leather (e) which passes on each side of it between the two screw pins f, holes
being formed at each end of the strips of leather so as to pass upon the screw pius.
The excentric (g) is cast upon the boss of a pulley (g) which is free upon
a stud (1) secured by a screw to a bracket i fastened to the stand c; this
bracket (i) and stud (h) are adjustable by means of the slot (c) in the stand
and the slot (¹), in the bracket (i), for the stud (h). The pulley (9') is kept
upon the stud by a part k which is secured to it by a set screw, and this
part thus acts both as a collar and a receptacle for oil, the upper part being
made hollow and covered by a lid binged to one side. The oil passes from the
hollow in (k) through a hole in the side of the stud (h), then along its hollow
axis, and then through two holes to a channel made in the surface of the stud,
and thus the pulley is lubricated. The pulley may be driven by a band, as
shown in dotted line in Fig. 1, either from a pulley (1) upon the axis of the

page_text: main card cylinder, or from a pulley (m) on the boss of the tightening
pulley D.
We have now particularly described the nature of our Invention and the
mode of carrying the same into effect, and claim as our Invention the com-
bination and arrangement of mechanism for giving motion to the doffer comb
of carding engines as herein-before described and shown in the Drawings.
In witness whereof, we, the said Alfred Travis and Benjamin Travis,
have hereunto set our hands and seals this Twenty-eighth day of
October, in the year of our Lord One thousand eight hundred and
sixty-two.
