page_text: LETTERS PATENT to John Carter, of Halifax, in the County of York,
Cotton Spinner, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR SPINNING, TWISTING, AND DOUBLING FIBROUS SUBSTANCES.”*
FOR
SPINNING, TWISTING, AND DOUBLING FIBROUS SUBSTANCES.'
Scaled the 29th February 1876, and dated the 31st August 1875.
PROVISIONAL SPECIFICATION left by the said John Carter at the
Office of the Commissioners of Patents, with his Petition, on the
31st August 1875.
I, JOHN CARTER, of Halifax, in the County of York, Cotton
Spinner, do hereby declare the nature of the said Invention for "Iм-
PROVEMENTS IN MACHINERY FOR SPINNING, TWISTING, AND DOUBLING FIBROUS
SUBSTANCES," to be as follows :-
This Invention relates,—

page_text: from end to end of the machine. In cach plate is a hole corresponding
in size with the ring to be used. On each side of this hole a portion of
the metal is turned down in the form of a rim, and to attach the ring
thereto it is only necessary to compress it slightly and place it between
the two rims of the plate, where it is firmly held by the clasticity of the
material of which it is made.
Secondly. My Invention relates to means to be employed when
spinning direct from rovings or condensings, and my object is to prevent
the roving from stretching between the hobbin and the drawing rollers.
For this purpose I employ a small tube, upon which is a wharle or
pulley, and this tube I place between the bobbin and the drawing
rollers, with one end thereof close to the said drawing rollers. On
rotation being communicated to the tube the portion of roving between
it and the bobbin becomes twisted, and consequently stronger, which
prevents it from stretching, but on leaving the tube the twist is taken
out, and it is presented to the drawing rollers in the same state as it left
the bobbin.
Thirdly. My Invention consists in employing a fixed spindle when
using upright or reversed flyers, the flyer revolving loosely upon the
spindle and carrying the bobbin round by the tension of the thread; by
so doing I am enabled to produce greater tension or drag upon the
thread, and also to prevent the bobbin from overrunning itself when the
machine stops.
"
Fourthly. This Invention relates to a novel arrangement of the bands
for driving the spindles of such machinery, and is adapted more
especially to machinery in which what are known as "endless bands
are used. The chief objection to "endless" bands is that when a band
breaks it is necessary to remove every band between it and one end of
the machine, and also to take the tin cylinder out of its bearings before
the band can be replaced. This causes a great loss of time and trouble,
which is avoided by my arrangement. For a full explanation of this I
refer to the accompanying Sheet of Drawings. I make the band long
enough to serve for four spindles, two on each side of the machine, and
instead of a tin cylinder I employ a shaft, upon which are a number of
grooved pullies, one pulley driving four spindles. The band is placed
on the spindles in the following manner:-The spindle A is taken out
of its footstep and passed through the band, which is then carried over

page_text: the pulley B, one portion entering the groove, the other passing over the
shaft. The portion entering the groove is carried underneath and round
the pulley C (which is raised out of its footstep and passed through the
band) to the opposite side of the machine, round the two pullies E and
D, which are removed and replaced inside the band. It will be seen
that the four pullies travel in the same direction. To avoid friction on
the shaft the pullies C and E are placed lower on the spindles than the
pullies A and D. With this arrangement either bands, straps, or tapes
may be employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Carter in the Great Seal Patent Office on the
29th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Jonn
CARTER, of Halifax, in the County of York, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of August, in the year
of our Lord One thousand eight hundred and seventy-six, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Carter, Her special licence
that I, the said John Carter, my executors, administrators, and
assigns, or such others as I, the said John Carter, my 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 FOR SPINNING, TWISTING, AND DOUBLING FIBROUS SUBSTANces,” upon
the condition (amongst others) that I, the said John Carter, my
executors or administrators, by an instrument in writing under my,
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.

page_text: NOW KNOW YE, that I, the said John Carter, do hereby declare
the nature of my 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 Sheet of Drawings, that is
to sav

page_text: placed within the band. To avoid friction on the shaft the wharles on
the spindles are placed at different heights.
This variation may be greatly lessened by the plan shewn in Figs. 5
and 6, where the band is passed around the moveable pulley G, which
serves both for a guide and tightening pulley.
The manner of placing the band in position is similar to that in the
case previously described, and will be more readily understood from an
inspection of the Drawings than from a written description.
In order that the corresponding parts of the band (supposed to be
stationary) may be recognized they are numbered, the numbers in
Figs. 3 and 4 referring to each other, as also do those in Figs. 5
and 6.
I purposely omit and relinquish those parts of my Invention described
under the second and third sections of my Provisional Specification, and
confine my claims to,―
Firstly. The method of suspending the "rings" of the ring flyers,
substantially as shewn and described.
Secondly. The arrangement of driving bands (whether "endless" or
not), whereby the same may be removed and replaced without the
necessity of either removing the driving shaft or disconnecting the ends
of the band, as herein shewn and described, or any mere modification
thereof.
In witness whereof, I, the said John Carter, have hereunto set
my hand and seal, this Twenty-sixth day of February, in the
year of our Lord One thousand eight hundred and seventy-
six.
