Year: 1870

page_text: LETTERS PATENT to William Hoyle, Manager, Joseph Harrison,
Foreman, and Joseph Rothera, Engineer, all of Bradford, in the
County of York, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND TWISTING FIBROUS SUBSTANCES.
Sealed the 31st March 1871, and dated the 3rd October 1870.
PROVISIONAL SPECIFICATION left by the said William Hoyle, Joseph
Harrison, and Joseph Rothera at the Office of the Commissioners of
Patents, with their Petition, on the 3rd October 1870.
We, WILLIAM HOYLE, Manager, JOSEPH HARRISON, Foreman, and
JOSEPH ROTHERA, Engineer, all of Bradford, in the County of York,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY FOR SPINNING AND TWISTING FIBROUS SUBSTANCES," to be as
follows:-
66
This Invention relates to that class of machinery for spinning and
twisting fibrous substances technically known as 'frames," and the
object is to effect or produce more even and elastic yarn or thread than
heretofore, and consists in having the bottom front roller constructed

page_text: hollow (instead of solid as heretofore) so that steam, hot water, or other
heating media may be introduced or passed through it. Also in the appli-
cation of one, two, or more brass or other metal tubes or pipes (for the
said heating media to pass through) placed behind the front rollers or
between them and the bobbin board. The rovings or yarns are caused
to pass over, under, or between the said tubes or pipes (and between the
front rollers as usual) and receive heat therefrom, whereby we obtain the
desired object.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Hoyle, Joseph Harrison, and Joseph
Rothera in the Great Seal Patent Office on the 3rd April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
HOYLE, Manager, JOSEPH HARRISON, Foreman, and JOSEPH ROTHERA,
Engineer, all of Bradford, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of October, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said William Hoyle, Joseph Harrison, and Joseph
Rothera, Her special licence that we, the said William Hoyle, Joseph
Harrison, and Joseph Rothera, our executors, administrators, and
assigns, or such others as we, the said William Hoyle, Joseph
Harrison, and Joseph Rothera, our 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 AND TWISTING FIBROUS SUBSTANCES," upon the condition (amongst
others) that we, the said William Hoyle, Joseph Harrison, and Joseph
Rothera, our executors or administrators, by an instrument in writing
under our, 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 we, the said William Hoyle, Joseph Harrison,
and Joseph Rothera, do hereby declare the nature of our 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 accom-
panying Sheet of Drawings, that is to say :-
This Invention relates to that class of machinery for spinning and
twisting fibrous substances technically known as "frames" and the
object is to effect or produce more even and elastic yarn or thread than
heretofore, and consists in having the bottom front roller shaft con-
structed hollow (instead of solid as heretofore) so that steam, hot water,
or other heating media may be introduced or passed through it. Also
in the application of one two or more brass, or other metal tubes or
pipes (for the said heating media to pass through) placed behind the
front rollers or between them and the bobbin board. The rovings or
yarns are caused to pass over, under, or between the said tubes or pipes,
(and between the front rollers as usual) and receive heat therefrom,
whereby we obtain the desired object.
In order that this Invention may be clearly understood we herein give
reference to an accompanying Sheet of Drawings a twisting or doubling
frame with our improvements applied thereto.
Fig. 1 is an end view, and Fig. 2 is a cross section of same; A. is
the bottom front roller shaft, which, as will be seen, is hollow, so that
steam, hot water, hot air, or other heating media or fluid may be intro-
duced therein when the said shaft becomes heated thereby, and it heats
the rollers B fixed thereon, and these rollers by contact communicate
heat to the top rollers C. Behind the front rollers are two metal pipes
or tubes D and E, which are connected at one end of the frame by
another short pipe F, and the former is connected at the opposite end
by a pipe G to the hollow shaft A, so that the steam or other heating
media may circulate through the shaft and pipes, and which may be
introduced either into the pipe E and exhausted or discharged from
the shaft A into an ordinary syphon box, or visa versa introduced to the
shaft A and discharged from the pipe E. A suitable stuffing box joint
is requisite to be made at the connection of the shaft A with the pipe,
as will be understood. These pipes or tubes B and C by preference are
of drawn iron enamelled with glass or coated with porcelain, but may
be of smooth brass or other metal or material that the yarn will slip or
slide easily over.

page_text: It will now be observed that the yarn is caused to pass from the
bobbins H over the roller E and under the roller D, thence under the
roller B and over the roller C, and thence to the ordinary flyer I for twist-
ing and winding it on the bobbin J which is carried on the spindle K in
the usual manner.
It will also be readily perceived that the Invention is equally applic-
able to spinning frames as to doubling or twisting frames, the pipes
being suitably placed and arranged according to circumstances.
Having thus described the nature of our said Invention and shewn
by Drawings and explanation in what manner the same is and may be
performed or put into practice, we would have it understood that we do
not confine ourselves to any particular details in the mode or manner
of applying our improvements, but what we claim as of our Invention,
is,-
Firstly. The constructing of the bottom front roller shaft hollow,
and the application and use of one or more metal tubes behind or
between the said roller and the bobbin board for the purpose of intro-
ducing heat to the rovings or yarns when spinning and doubling or
twisting.
Secondly. The method of applying heat to the rovings or yarns in
the process of spinning, doubling, or twisting by means of steam, hot
water, hot air, or other heating appliances in manner substantially as
shewn and described.
In witness whereof, we, the said William Hoyle, Joseph Harrison,
and Joseph Rothera, have hereunto set our hands and seals, this
Thirtieth day of March, in the year of our Lord One thousand
eight hundred and seventy-one.
