IMPROVEMENTS IN PREPARING AND SPINNING WOOL AND OTHER FIBROUS SUBSTANCES."
Year: 1866

page_text: LETTERS PATENT to Louis John Crossley, of Willow Hall, near Halifax,
and Joseph Sunderland, of Halifax, in the County of York, for the
Invention of "IMPROVEMENTS IN PREPARING AND SPINNING WOOL AND OTHER
FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Louis John Crossley and
Joseph Sunderland at the Office of the Commissioners of Patents, with
their Petition, on the 14th July 1866.
We, Louis JOHN CROSSLEY, of Willow Hall, near Halifax, and JOSEPH
SUNDERLAND, of 1Ialifax, in the County of York, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN PREPARING AND SPINNING WOOL
AND OTHER FIBROUS SUBSTANCES," to be as follows
Heretofore it has been usual to employ a system of 1ollers, termed carrier
rollers, between the back and front rollers of drawing, roving, and spinning
frames, the object of which is to prevent the twist leaving the slubbing or
roving too soon before reaching the front roller.
Our improvements consist in dispensing with these said "carrier rollers,"
and in substiting therefor a length of wood, metal, pottery, or a combination
thereof, over which the slubbing or roving passes on its way to the front
roller, and we so arrange this said piece of wood or material that its position
in relation to the back and front rollers can be altered at pleasure, either
backwards or forwards, or elevated, or depressed.
The advantages arising from this Invention are manifold, amongst others

page_text: is the ease with which when new rovings or slubbings are put into a spinning
frame they may be passed forward; there is also a great saving in oil, and
in the wear and tear, owing to the increased simplicity of the machine, as well
as a great economy in the cost of the frame; the very general evil of lapping
on the carrier rollers is also got rid of, and the yarn produced is superior in
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
hy the said Louis John Crossley and Joseph Sunderland in the Great
Seal Patent Office on the 7th November 1800.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Louis
JOHN CROSSLEY, of Willow Hall, Halifax, and JOSEPH SUNDERLAND, of Halifax,
in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of July, in the year of our Lord
Oue thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
dil, for Herself, Her heirs and successors, give and grant unto us, the said
Louis John Crossley and Joseph Sunderland, Her special licence that we, the
said Louis John Crossley and Joseph Sunderland, our executors, adminis-
trators, and assigns, or such others as we, the said Louis John Crossley and
Joseph Sunderland, 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 "IMPROVE-
MENTS IN PREPARING AND SPINNING WOOL AND OTHER FIBROUS SUBSTANCES," upon
the condition (amongst others) that we, the said Louis John Crossley and
Joseph Sunderland, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, or under the hand
and seal of one of us, or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formned, 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 we, the said Louis John Crossley and Joseph
Sunderland, do hereby declare the nature of the said Invention, and in what

page_text: manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
Drawing hereunto annexed, and to the letters and figures marked thereon
(that is to say):
Ileretofore it has been usual to employ a system of rollers, termed carrier
rollers, between the back and front rollers of drawing, roving, and spinning
frames, the object of which is to prevent the twist leaving the slubbing or
roving too soon before reaching the front roller.
Our improvements consist in dispensing with these said "carrier rollers,
and in substituting therefor a length of wood or material, over which the
slubbing or roving passes on its way to the front roller, and we so arrange
this aid piece of wood or material that its position in relation to the back and
front rollers can be altered at pleasure, either backwards or forwards, or
elevated or depressed.
Having thus stated the nature of our Invention, we will proceed more fully
to describe the manner of performing the same.
The Drawing represents so much of a transverse section of a machine as
will enable a workman, aided by the description herein contained, fully to
understand the Invention and how it may be performed. We would, however,
here state that we do not confine ourselves to the precise arrangement shown
in the Drawing so long as the peculiarity of our Invention be retained, which
consists in dispensing with the carrying rollers, and introducing a carrying
surface of wood or other suitable material, as before stated, in place of such
carrying rollers.
a, a, and b, b, are the ordinary front and back rollers, and heretofore the
carrying rollers were applied and used intermediate of the rollers a, a, and
b, b. These in the arrangement shown are dispensed with, and in place
thereof the surface c of wood or other suitable material is applied, which is
made capable of adjustment by screws d as is shewn ; these screws are tapped
into a bar or rail e, and by means of them the surface c can either be raised
or lowered bodily, and either edge may be elevated or depressed. The rail e
is clamped to the inclined rack f, which forms part of the frame, by the
screw 9, so that by shifting the bar or rail e on the rack the surface c can be
set nearer to or further from the front rollers a as may be required, according
to the distance at which the rollers a and b are set.
The advantages arising from this Invention are manifold, amongst others
in the ease with which new rovings or slubbings are put into a spinning
frame and passed forward; there is also a great saving in oil, and in the

page_text: wear and tear, owing to the increased simplicity of the machine, as well as a
great economy in the cost of the fiame; the very common evil of lapping on
the carrier rollers is also avoided, and the yarn produced is superior in evenness
and lustre to that spun in the old way.
In witness whereof, we, the said Louis John Crossley and Joseph
Sunderland, have hereunto set our hands and seals, this Eighth day of
October, in the year of our Lord One thousand eight hundred and
Sixty-six.
LOUIS JOHN CROSSLEY. (LS)
