IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING; TWISTING, OR WINDING WOOL, SILK, COTTON, FLAX, OR OTHER FIBRES."AL
Year: 1874

page_text: LETTERS PATENT to John Carter Ramsden, of Smith House, Light-
cliffe, in the County of York, Silk Manufacturer, for the Invention
✓ of "IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING; TWISTING, OR
WINDING WOOL, SILK, COTTON, FLAX, OR OTHER FIBRES."
PROVISIONAL SPECIFICATION left by the said John Carter Ramsden
at the Office of the Commissioners of Patents, with his Petition, on
the 25th February 1874.
I, JOHN CARTER RAMSDEN, of Smith House, Lightcliffe, in the County
of York, Silk Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING, TWISTING,
OB WINDING WOOL, SILK, COTTON, FLAX, OR OTHER FIBRES," to be as follows:―

page_text: Secondly. To an improvement in the construction of the spindles
employed thereon.
The driving belt, band, or tape passes from the main driving pulley
over the wharle or pulley on one or more of the first spindles of the
scries, then over "a friction pulley" placed between and at the opposite
side of the next two spindles, then to the front of and over one or more
of the wharles or pulley on the next one or more spindles, thence over
another friction pulley placed between the wharles of the next pair of
spindles, and so on over the whole series of spindles on one side of the
"frame," whence it passes over guide and stretching pulleys to and over
the wharles and friction pulleys on the other side of the frame in the
order as described above.
The friction pulley above referred to is in contact with the wharles or
pulleys on the two spindles botween which it is placed, so that each pair
of spindles having these intervening "friction pulleys" receive their 1
rotation therefrom, and such friction pulley also serves as a guide pulley
to divert the belt, band, or tape to the front of the next spindle or
spindles.
The stretching pulley is adjustable in its bearings so that the tension
on the belt, band, or tape may be regulated as required with facility, and 2
gives equal frictional contact throughout.
The spindles may be made of tubing wholly or in part of their length,
and provision made for the introduction of lubricant to the interior. The
lubricant to be used must be of a nature not to flow save in the event of
the foot of the spindle heating by friction. The foot of each spindle is 2
tapered to a centre, and perforations made to admit the flow of lubricant
to the footstep. Spindles so made are lighter, and create loss friction
than thoso heretoforo made solid.

Office on the 25th August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN CARTER
RAMSDEN, of Smith House, Lightcliffe, in the County of York, Silk
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of February, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Carter Ramsden, Her special
licence that I, the said John Carter Ramsden, my executors, admini-
strators, and assigns, or such others as I, the said John Carter
Ramsden, 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, DOUBLING, TWISTING, OR WINDING
WOOL, SILK, COTTON, FLAX, OR OTHER FIBRES," upon tho condition (amongst
others) that I, the said John Carter Ramsden, my executors or admi-
nistrators, 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
bo 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.
NOW KNOW YE, that I, the said John Carter Ramsden, 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 Shect of Drawings, that
is to say:-

page_text: :
imparting rotation to the spindles of such machinery, and consists as
follows:-
The driving belt, band, or tape passes from the main driving pulley
over the wharle or pulley on one or more of the first spindles of the
series, then over a "friction pulley" placed between and at the opposite
side of the next two spindles, then to the front of and over one or more
of the wharles or pulleys on the next one or more spindles, thence over
another friction pulley placed between the wharles of the next pair of
spindles, and so on over the whole series of spindles on one side of the
"frame," whence it passes over guide and stretching pulleys to and over
the wharles and friction pulleys on the other side of the frame in the
order as described above.
The friction pulley above referred to is in contact with the wharles or
'pulleys on the two spindles between which it is placed, so that each pair
of spindles having these intervening friction pulleys receive their rotation
therefrom, and such friction pulley also serves as a guide pulley to
divert the belt, band, or tape to the front of the next spindle or spindles.
The stretching pulley is adjustable in its bearings, so that the tension.
on the belt, band, or tape may be regulated as required with facility, and
gives equal frictional contact throughout.
In order that this Invention may be clearly understood reference is
given herein to an accompanying Sheet of Drawings in outline of a
'spinning frame or machine for spinning as aforesaid with my improve-
ments applied thereto.
Fig. 1 is a plan view or horizontal section of such parts of a frame
modified in construction as are necessary to illustrate my improved
method of driving the spindles. A are the series of spindles, and B the
rails supporting the same on both sides of a frame, which rails are made
wider than usual; C is the main driving pulley, or pulley which receives
motion from the mill shafting, and transmits same to the spindles by the
endless belt, band, or tape D, which passes in direct contact with two
spindles or the wharles thereon, then over a friction pulley E, which is
in contact with the next two spindles, the belt thence passing in contact
with the next two, thence over another friction pulley E', and so to the
whole series of spindles; G is a friction pulley with adjusting screw H
for regulating the tension of the belt.

page_text: Fig. 2 is a detail to further elucidate the parts of the apparatus, which
are marked with the same letters of reference as in Fig. 1.
Having now described the nature of the Invention, and shewn by
Drawings in what manner the same is to be performed, I wish it to be
understood that what I claim as my Invention is, the peculiar arrange-
ment of means and method of driving spindles of spinning machinery
as herein described and shewn by accompanying Drawings.
In witness whereof, I, the said John Carter Ramsden, have here-
unto set my hand and seal, this Twenty-fourth day of August,
in the year of our Lord One thousand eight hundred and seventy-
foun
JOHN CARTER RAMSDEN. (L.S.)
