Year: 1877

page_text: LETTERS PATENT to George Knowles, junior, of Bolton, in the County of Lan-
caster, Cotton Spinner, and Alfred Higgins, of Salford, in the said County,
Machine Maker, for the Invention of "IMPROVEMENTS APPLICABLE TO
MACHINERY FOR SLUBBING OR ROVING COTTON AND OTHER FIBROUS
MATERIALS"
Sealed the 1st September 1877, and dated the 12th March 1877.
PROVISIONAL SPECIFICATION left by the said George Knowles and Alfrod
Higgins at the Office of the Commissioners of Patents on the 12th March
1877.

MENTS APPLICABLE TO MACHINERY FOR SLUBBING OR ROVING COTTON AND OTHER
FIBROUS MATERIALS."
Our Invention relates to a method of obtaining a surface upon which the material
may be wound in place of the bobbins ordinarily employed. For this purpose we
provide the usual "braid," with a tube extending upward, and through which the
spindle passes, and instead of using the ordinary bobbin, we place a tube of paper,
leather, or other such inaterial upon the said "braid " tube, and upon it the material
is wound.
The paper or other such tube may be adapted so as to slip on freely, but fitting
sufficiently to wind without slipping when the slubbing or roving has the proper
tension, but free to move when the tension becomes excessive; or it may be
made to run positively with the "braid" by a spring notch or other ordinary
attachment.
7. humid juba may run either upon a short or long collar.
20 SPECIFICATION in pursuance of the conditions of the Letters Patont filed by
the said George Knowles and Alfred Higgins in the Great Seal Patent Office
on the 12th September 1877.

"" IMPROVE-

page_text: MENTS APPLICABLE TO MACHINERY FOR SLUBBING OR ROVING COTTON AND OTHER
FIBROUS MATERIALS."
Our Invention relates to a method of obtaining a surface upon which tho
material may be wound in place of the bobbins ordinarily employed. For this
purpose we provide the usual "braid" with a tube extending upward, and through
which the spindle passes, and instead of using the ordinary bobbin (that is with
notches at its lower end), we place in lieu thereof a simple tube upon the said
"braid" tube, and upon it the material is wound.
In the accompanying Drawing, Fig. 1 shews in section one form of our Invention;
at 1, is the spindle, running in what is commonly called a collar 2, and at 3 is the
"braid," extending upward and bearing at 3* against the spindle 1, and so far the
parts are in ordinary use. At 4 is a tube, supposed in this case to be made of
paper, and upon which the material is to be wound. This tube, when adapted for
use, is slipped on to the extension of the "braid "3, fitting it with sufficient friction
to enable the "braid " to drive it during the proper working of the machine, but
should the tension become excessive, the friction is overcome, and the said tube 4 is
caused to slip round and regulate the tension, but in addition to this, if the tubes
(as at 4) be made of paper, they may be secured of equal or nearly equal weights.
Figs. 2 and 3 shew a modification of our Invention. In this instance the spindle 1
runs as before in a collar 2, and the braid 3, instead of the former arrangement, being
provided with a short tube 5 only. At 4 is the tube constituting our Invention,
and made of wood if desired; its upper end runs upon the spindle 1, and its lower
end is slipped upon the extension 5 of the "braid," fitting it with a certain amount
of friction. Projecting from the braid are brackets 6, to which are jointed levers 7,
the lower ends thereof being provided with weights 8, and their upper ends 9 being
in contact with the tube 4. As the operation of winding proceeds, the tube 4 is
driven to a certain extent by the friction of contact between the tube 4 and the
part 5 of the "braid," but in addition to this the centrifugal force arising from the
revolution of the "braid," throws the weights 8 outward, and causes the parts 9 to
press against the tube 4, which is thus, as before, driven by friction only, and this
centrifugal arrangement may be adapted to the arrangement shewn at Fig. 1.
Fig. 4 shows another modification of our Invention. The "braid" is the same as
that shewn in Fig. 2, but running on a shorter collar 2, and the tube 4, which con-
stitutes our Invention, is of different shape and slipped over the bare spindle, but
the bottom thereof is adapted as before to the part 5 of the braid. At 8 is the cen-
trifugal weight, but in this instance, instead of the rigid finger 9, it is provided
with a spring 10, which presses with elastic force against the tube 4. One of these
pressers only is shewn in the Drawing, but there may be two or more.
Fig. 5 is a plan view of Fig. 4, and shews the top of the presser 9 notched as at
9*, in order to gain a firmer hold upon the tube 4.
Having thus described and ascertained the nature of our said Invention, and the
manner in which the same is to be performed, I desire it to be understood that we
claim as secured to us under the above in part recited Letters Patent, and for the
purposes above set forth, the use of simple tubes acting as bobbins in the manner
described, whereby the necessity for slots or other such parts by which they are
commonly driven is dispensed with.
In witness whereof, I, the said Alfred Higgins, have hereunto set my hand'
and seal, this Eleventh day of September, in the year of our Lord One
thousand eight hundred and seventy-seven.
