page_text: LETTERS PATENT to Alfred Pemberton, of Eccles, in the County of Lan-
caster, Agent, and Alfred William Pemberton, of the same Place, Clerk,
for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
SPINNING, DOUBLING, OR TWISTING COITON, AND OTHER FIBROUS MATERIALS,"
Sealed the 1st December 1865, and dated the 6th June 1865.
PROVISIONAL SPECIFICATION
SPECIFICATION left by the said Alfred Pemberton and
Alfred William Pemberton at the Office of the Commissioners of
Patents, with their Petition, on the 6th June 1865.
We, ALFRED PEMBERTON, of Eccles, in the County of Lancaster, Agent, and
ALFRED WILLIAM PEMBERTON, of the same Place, Clerk, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY Ox
APPARATUS FOR SPINNING, DOUBLING, OR TWISTING COTTON, AND OTHER FIBROUS
MATERIALS," to be as follows:-
Our Invention relates, firstly, to an improvement upon a method of
obtaining the drag in throstle frames, for which Letters Patent were granted
to Alfred Pemberton, dated Dec 13th, 1864, No. 3087, but which is also
applicable to other methods of obtaining the drag.
According to our Invention we apply a false bottom or flange to the bobbin,
and which may remain permanently in the machine. This false bottom or
flange may be connected to the bobbin when in use by a pin projecting into
a recess, or similar ordinary contrivance. Against this false bottom the drag
apparatus described under the aforesaid Patent of Alfred Pemberton is
Price Sd 1

page_text: applied. Or we put on the drag by passing cords with tension over the
periphery of the said false bottom or flange, as is now, practised in some
descriptions of spinning, twisting, or doubling machinery.
Secondly, our Invention consists in applying flanged bobbins for receiving the
material to be spun, doubled, or twisted, to flanged tubes mounted upon the
spindles, and resting by flanges upon the rail. When the bobbins are to be
doffed they are lifted from these tubes which remain upon the spindles. The
bobbins may be adapted either end downward, accordingly as one end becomes
worn or injured.
Thirdly, our Invention consists in a method of regulating the drag, which
is ordinarily obtained by passing cords over the flanges of the bobbins. This
we accomplish by connecting the said cords with set screws, by the turning of
which the tension may be diminished or increased.
Fourthly, our Invention relates to guides for conducting the material from
the rollers to the flyers. For this purpose instead of the usual wire or curl
we employ a curved plate, upon which the material runs on its passage, and
by which it is therefore guided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Pemberton and Alfred William Pemberton in the
Great Seal Patent Office on the 6th December 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALFRED
PEMBERTON, of Eccles, in the County of Lancaster, Agent, and ALFRED
WILLIAM PEMBERTON, of the same Place, Clerk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of June, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Alfred Pemberton and Alfred William Pemberton, Her special license
that we, the said Alfred Pemberton and Alfred William Pemberton, our
executors, administrators, and assigns, or such others as we, the said Alfred
Pemberton and Alfred William Pemberton, 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 MACHINERY OR APPARATUS FOR

page_text: SPINNING, DOUBLING, OR TWISTING COTTON, AND OTHER FIBROUS MATERIALS," upon
the condition, amongst others, that we, the said Alfred Pemberton, and Alfred
William Pemberton, by an instrument in writing under our hands and seals,
(or under the hand and seal of one of us), 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 I, the said Alfred Pemberton, 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:-
One part of our Invention, according to our Provisional Specification,
related to a method of guiding the yarn to the flyer, but since the filing
thereof we have found that the same is not of practical utility, and therefore
lay no claim thereto.
Our Invention consists in an improved method of obtaining the drag in
throstle frames or other such machines in which a drag upon the bobbin is
required.
Figs. 1 and 2 represent one method of carrying out our Invention.
A throstle spindle is shewn at a, mounted as usual in the lifting rail b, and
carrying the bobbin c. Between the flange of the bobbin and the. copping
rail we place a disc d, of wood, metal, or other suitable material, which disc is
caused during the operation of the machine to run with the bobbin by means
of a pin e situate in a hole formed in the flange of the bobbin. Against the
periphery of the disc d we place a spring, or cause a weight to act thereon,
so as to generate friction, and effect the required drag.
In the Drawing that apparatus for effecting the drag is shewn for which
Letters Patent were granted to me, Alfred Pemberton, in conjunction with
John Ford, dated December Thirteenth, One thousand eight hundred and
sixty-four, Number 3087, in that case, however, the apparatus acted imme-
diately upon the flange of the bobbin, whereas according to our present
improvement it acts through the medium of the separate flange or disc d.
The said apparatus is as follows:-At f is a bracket attached to the lifting
rail, which bracket is tapped for the reception of a set screw (. The inward
end of this screw is connected to a bowed spring h, to the ends of which is
attached a strip of flannel, or other soft substance i, and bearing against the
periphery of the disc d. By turning the set screw g backward or forward
the pressure of the flannel i upon the disc d is loosened or tightened, and the

page_text: ::drag decreased or increased at pleasure." According to this system there is a
i set screw. g and appendages for each spindle, and the requirements" of each
bobbin may therefore be attended to, the brackets f may, however, be wide
enough to carry two or more set screws.g. When the bobbin is full, and is
doffed as usual, the disc d is left on the lifting rail, and it will be seen there-
fore that the surface against which the drag acts is not liable to damage, and
remains uniform.
The above description explains the principle of our Invention, and the
arrangement pointed out may be used; we prefer, however, generally to
employ the modification shewn at Fig. 3, in which the bobbin c is, as before,
united when running to a disc d, by means of a pin e, but in this case a
washer is placed between the said disc d and the copping rail b. The
washer is not connected to the disc d, but is at liberty to turn upon the
rail independently thereof. By this arrangement a portion of the drag
which would be caused by the disc d running upon the rail is destroyed,
and a starting point involving a smaller amount of friction is obtained, and
this may be increased to the required extent by the set screw g, and its
appendages, described in reference to Figs. 1 and 2, which are, of course, to
be applied as in the former instance. The original amount of friction (to be
increased to the desired point by the screw g) may be varied according to the
yarn to be twisted by changing the washer k for another of greater or smaller
diameter.
Figs. 4 and 5 shew another method of decreasing the friction between the
disc d and rail b. In this instance the said disc is provided with a ring of
metal, which rests upon the rail b. In Fig. 6 is another form with the same
object, the disc being turned to a smaller diameter at m, and hollowed out.
Figs. 7 and 8 shew our Invention in conjunction with another and known
method of regulating the drag. In this instance a cord n passes partly
around the disc d, which cord is attached at one end to the back of the
rail b, and the other end is provided with a weight p, which may be shifted, so
as to cause the cord n to lap more or less around the disc d. This shifting
cord is well known as applied direct to the flange of the bobbin. It will be
seen that by our Invention the two flanges of the bobbin may be of the same
form, and that it may therefore be turned end for end when injured.
We have in the foregoing description described certain methods of retarding
the disc d, so as to obtain the drag, but we do not confine ourselves thereto,
as other arrangements of springs, weights, or other equivalents may be
employed; that which we claim as secured to us under the above in part
recited Letters Patent, and for the purpose above set forth, being the use of a

page_text: surface running with the bobbin when the drag is required, but from which
the bobbin may be detached for doffing.
In witness whereof, I, the said Alfred Pemberton, have hereunto set
my hand and seal, this Fifth day of December, in the year of our Lord
One thousand eight hundred and sixty-five.
ALFRED PEMBERTON. (L.s.)
