IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING, AND TWISTING FIBROUS SUBSTANCES
Year: 1873

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, DOUBLING, AND TWISTING FIBROUS SUBSTANCES."
Scaled the 19th December 1873, and dated the 26th June 1873.
PROVISIONAL SPECIFICATION left by the said John Carter at the
Office of the Commissioners of Patents, with his Petition, on the
26th June 1873.
I, JOHN CARTER, of Halifax, in the County of York, Cotton Spinner,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY FOR SPINNING, DOUBLING, AND TWISTING FIBROUS SUBSTANCES," to
be as follows:-
This Invention relates to improvements in machinery for spinning,
twisting, or doubling wool, silk, cotton, or other fibrous substances, and
the object is to impart the required rotation to the spindles without the
aid of the driving drum or tin cylinder, and separate driving cord or
band for each spindle as heretofore.

page_text: I employ a number of grooved guide pullies attached to convenient
parts of the frame, so as to guide and direct a band, tape, or strap
(working over the said pullies) to bear on and in the groove of the warle
on each spindle, and by the friction so produced thereon to impart the
necessary rotation to the spindles. The driving band or tape receives
its motion from a grooved pulley on the driving shaft.
In some cases the said shaft may be continued from end to end of the
"frame," and a driving pulley for the band be employed at each end of
the said shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Carter in the Great Scal Patent Office on
the 24th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
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 Twenty-sixth day of June, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Carter, Her special
licence that I, the said John Carter, my executors, admini-
strators, and assigns, or such others as I, the said John Carter,
my exccutors, 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, DOUBLING, AND TWISTING FIBROUS SUBSTANCES," upon
the condition (amongst others) that I, the said John Carter, my exccutors
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 Scal 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
say:-
This Invention relates to improvements in machinery for spinning,
twisting, or doubling wool, silk, cotton, or other fibrous substances, and
the object is to impart the required rotation to the spindles without the
aid of the driving drum or tin cylinder, and separate driving cord or
band for each spindle.
I employ a number of guide pulleys attached to convenient parts of
the frame, so as to direct and guide a band, tape, or strap working over
the said pulleys to bear on and in the groove of the wharle, or on and
against the pulley on each spindle, and by the friction so produced
thereon impart the necessary rotation to the spindles. The driving band
or tape receives its motion from a pulley on the driving shaft.
In some cases the said shaft may be continued from end to end of the
frame, and a driving pulley for the band be employed at each end of the
said shaft or other part of the length of the frame.
The nature and particulars of this Invention are fully set out in and
by the following description, aided by Drawings, in the latter of which
Fig. 1 is an end clevation of such parts of a "frame" as are necessary
to illustrate the application of these improvements thereto; Fig. 2 is a
sectional plan of Fig. 1; Figs. 3, 4, 5, 6, and 7 are details or views of
the separate parts drawn about full size.
A is the framework of the machine; B, B, are the ordinary fast and
loose pulleys on the shaft C, on which shaft is the pulley E, which gives
motion to the band, tape, or strap F; G, G, are stretching. pulleys,
which may be moved in the slot g, g, so as to tighten the said band, tape,
or strap, which latter is by means of the guide pulleys H guided or
directed so as to bear on and in the groove of the wharle J of each
spindle, or on and against the pulley J of each spindle. The friction of
the band, tape, or strap F on the wharle or pulley H, as the case may
be, imparts the requisite rotation to the spindle on which such.appliance
is attached.
I would have it understood that the guide pulleys H are to be adjusted
or placed in position relatively to the position of the wharves or pulleys J

page_text: on the spindles, so as to ensure the band, tape, or strap bearing on and
against the said wharves or pulleys J, in such degree only as to give the
amount of friction necessary to drive the spindles and no more, because
if the said guide pulleys are so placed as to bear on the said band, tape,
or strap more than is requisite to accomplish that object there is, an
unnecessary amount of power required for driving the same, and more
wear and tear both of the driving band, strap, or tape, and of the necks
and spindles.
The drawing rollers may receive rotation from one of the guide
pulleys (say H¹) by means of the train of gearing shown at Fig. 8, so that :
in the event of breakage or damage to the band, tape, or strap, the
spindles and the drawing rollers cease simultaneously to move and rotate;
consequently there can be no breakage of ends.
The driving strap or tape I prefer should be double, that is to say, two
straps or two tapes secured together, whereby the defective and uneven ]
jointing (when a single strap is employed) is avoided. An even and
true surface is secured throughout the strap or tape so made.
Having thus fully described the nature and particulars of this my
said Invention, together with the manner in which the same is to be
or may be performed or carried into practical effect, I would have it?
understood that I claim as my Invention, the use or employment of the.
guide pulleys H, applied and arranged as herein described and shewn in
the accompanying Drawings, for the purpose of maintaining the strap,
tape, or band F in contact with the wharles or pulleys J, and thereby to
impart the necessary rotation to the spindles.
In witness whereof, I, the said John Carter, have hereunto set
my hand and seal, this Twenty-third day of December, in the
year of our Lord One thousand eight hundred and seventy-
three.
