IMPROVE- MENTS IN MACHINERY OR APPARATUS FOR SPINNING, DOUBLING, AND TWISTING WOOL OR OTHER FIBROUS SUBSTANCES."
Year: 1873

page_text: LETTERS PATENT to Frederick Smith, of Ravensthorpe Mills, Mirfield,
in the County of York, Overlooker, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR SPINNING, DOUBLING, AND TWISTING
WOOL OR OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Frederick Smith at the
Office of the Commissioners of Patents, with his Petition, on the
29th May 1873.
I, FREDERICK SMITH, of Ravensthorpe Mills, Mirfield, in the County
of York, Overlooker, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING, DOUBLING,
AND TWISTING WOOL OR OTHER FIBROUS SUBSTANCES," to be as follows:-
-
This Invention relates to that class of machinery for purposes above,
known as hand mules, and to self-acting mules, and the object of the
Invention is the construction, arrangement, and application of apparatus
to such machinery so as to admit of two or more threads being spun on
one mule at the same time, and also that such threads may when

page_text: required be doubled on the same mule, and so not only produce two
threads at the same time on one machine, but also of doubling on the
same machine as the spinning is effected, I dispense with the use of a
separate machine for doubling, with consequent economy of time, labour,
and power required as heretofore.
In constructing mules, whether hand mules or self-acting, according
to this Invention, I affix at the back or near to the ordinary single
condenser drums, a standard or standards, and mount thereon an
additional condenser drum or drums, the condensed fibre from which is
passed through the operation of spinning, and it will be seen that the
operative can readily draw from any one or more of such condensers,
and that the doubling of two or more of the threads will at once be
effected on such threads being connected to the twist spindles.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Smith in the Great Seal Patent Office
on the 29th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
SMITH, of Ravensthorpe Mills, Mirfield, in the County of York, Over-
looker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of May, in the year
of our Lord One thousand cight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Frederick Smith, Her special licence
that I, the said Frederick Smith, my exccutors, administrators, and
assigns, or such others as I, the said Frederick Smith, 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 OR APPARATUS FOR SPINNING, DOUBLING, AND TWISTING WOOL OR OTHER
FIBROUS SUBSTANCES," upon the condition (amongst others) that I, the
said Frederick Smith, my executors or administrators, by an instrument

page_text: 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.
NOW KNOW YE, that I, the said Frederick Smith, 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 the class of machinery for purposes above,
known as hand mules, and to self-acting mules, and the object of the
Invention is the construction, arrangement, and application of apparatus
to such machinery, so as to admit of two or more threads being spun
on one mule spindle at the same time, and also that such threads may
be doubled on the same mule, and so not only produce two threads at
the same time on one machine, but also by doubling on the same
machine as the spinning is effected, I dispense with the use of a separate
machine for doubling, with consequent economy of time, labour, and
power required as heretofore.
In constructing mules, whether hand mules or self-acting, according
to this Invention, I affix at the back or near to the ordinary single
condenser drums, a standard or standards, and mount thereon an
additional condenser drum or drums, the condensed fibre from which is
passed through the operation of spinning, and it will be seen that the
operative can readily draw from any one or more of such condensers,
and that the doubling of two or more of the threads will at once be
effected on such threads being connected to the twist spindles.
In order that this Invention may be clearly understood, I herein give
reference to an accompanying Sheet of Drawings, illustrative of the
same.
Fig. 1 is an elevation of such parts of an ordinary self-acting mule
as are necessary to illustrate my Invention, Fig. 2 being a detail of
same.
A is the ordinary condenser drum or bobbin, and B, the surface
roller mounted on the framework C; D is a standard on which are

page_text: mounted an additional condenser drum E and surface roller F, the
condensed fibre from which is passed along with the fibre from the
drum A to the twist spindle G, and the two threads are passed through
the operation of spinning and doubling simultaneously, thus dispensing
with the use of a separate machine for doubling.
It will be readily seen that by the use of a greater number of drums
more than two threads may be twisted and doubled together.
Having thus described the nature of my Invention, and shewn the
manner in which the same is performed, I would have it understood that
I do not confine myself to the precise details of construction or arrange-
ment of apparatus as herein shewn and described, but what I claim as
my Invention is, the method of spinning and doubling two or more
threads of fibrous substances simultaneously, whereby a separate machine
for doubling is dispensed with, in manner substantially as shewn and
described.
In witness whereof, I, the said Frederick Smith, have hereunto
set my hand and seal, this Twenty-sixth day of November, in
the year of our Lord One thousand eight hundred and seventy-
