CERTAIN IMPROVEMENTS IN SPINNING AND SLUBBING MACHINES
Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HIRST, of Leeds, in the County of York, Cloth Manufacturer, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eleventh day of January, in the fifth year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
William Hirst, His especial licence, that I, the said William Hirst, my exors,
admors, and assigns, or such others as I, the said William Hirst, my exors,
admors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS
IN SPINNING AND SLUBBING MACHINES;" in which said Letters Patent there is
contained a proviso obliging me, the said William Hirst, by an instrument in
writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in His said Majesty's High Court of
Chancery within six calendar months next and immediately after the date
of the said recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Hirst, do hereby declare that the nature of my said Invention

page_text: consists in adding a second row of spindles to the machines now used for
spinning woollen threads, by which I am enabled to spin double the quantity
in nearly the same space and in the same time with the same machine;
but to effect this I am obliged to vary several parts of the machine,-for
instance, I am obliged to arrange the warls and bands in such a manner that t
they shall not, from their increased number, interfere with each other. The
supply of slubbing also to be spun must be double the former quantity; to put
which in the same or nearly the same space, requires a new arrangement of
the creels. The rollers also under which the thread passes in mules have
heretofore been fluted under each thread, and a plain surface left between 1
each thread; but to meet the necessities of the increased number of threads I
have been obliged to flute the whole length of the rollers, since by my new
arrangement I occupy that which on the old plan was spare space on the
rollers. And in further compliance with the said proviso, I, the said William
Hirst, do hereby describe the manner in which I perform my said improve-
ments by the following description thereof, reference being had to the Drawing
annexed, and the Figures marked thereon (that is to say) :-
DESCRIPTION OF THE DRAWING.
Figure 1 is an end view of a spinning machine. A, B, are two additional
creels of slubbing, leading, as usual, under the rollers e, r, the under of which
rollers is fluted in its whole length instead of partially, as is generally the case;
from these rollers the threads pass horizontally and beside one another to
the spindles, two of which only I have shewn, though, of course, there would
be four, one to each thread; but as the other two would be in a line with those
represented, of course they could not be seen in this view. C is a spindle in
its usual situation, and a is one of my said extra spindles, shewing its relative
position on the frame. It will be seen that this spindle is on one side of and
a little behind the ordinary spindle; and, in order that the warls and bands
should not interfere with each other, it will be seen how widely they are
placed apart, with reference to each other. Fig. 2 is a plan of the said
spindles; those marked a being my said extra row. Fig. 3 is a front view of
part of a spinning machine, shewing one scries of spindles, and the manner in
which the warls and bands are arranged.
Now, whereas, I claim as my Invention the following improvements (that is
to say) The two additional rows of creels of slubbing marked A and B, when
my said improvements are applied to mules, and also the additional or extra row
of spindles marked a, whether applied to mules or billies, and the arrangement
of the warls and bands for giving motion to the same. And these, my said

page_text: improvements, as applied to the spinning of woollen threads, being, to the best
of my knowledge and belief, entirely new, and never before used in that part
of His said Majesty's United Kingdom of Great Britain and Ireland called
England, His Dominion of Wales, nor Town of Berwick-upon-Tweed, I do
hereby declare this to be my Specification of my said improvements, and that
I do verily believe this my said Specification doth comply in all respects, fully
and without reserve or disguise, with the proviso in the said herein-before in
part recited Letters Patent contained; wherefore I do hereby claim to maintain
exclusive right and privilege to my said improvements.
In witness whereof, I, the said William Hirst, have hereunto set my hand
and seal, this second day of July, in the year of our Lord One thousand
eight hundred and twenty-five.
