CERTAIN IMPROVEMENTS IN SLUBBING AND ROVING FRAMES FOR PREPARING FOR SPINNING COTTON, FLAX, AND OTHER FIBROUS SUBSTANCES."
Year: 1853

page_text: LETTERS PATENT to Weston Grimshaw, of Mosley, in the County
of Antrim, Ireland, Flax Spinner, for the Invention of “CERTAIN
IMPROVEMENTS IN SLUBBING AND ROVING FRAMES FOR PREPARING
FOR SPINNING COTTON, FLAX, AND OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Weston Grimshaw
at the Office of the Commissioners of Patents, with his Petition,
on the 30th April 1858.
I, WESTON GRIMSHAW, of Mosley, in the County of Antrim, Ireland,
Flax Spinner, do hereby declare the nature of the said Invention for
CERTAIN IMPROVEMENTS IN SLUBBING AND ROVING FRAMES FOR PREPARING
FOR SPINNING COTTON, FLAX, AND OTHER FIBROUS SUBSTANCES," to be
as follows, that is to say:-
According to the modes which have heretofore been in practice of
constructing machines of this class, the spindles have been usually
arranged in two parallel rows, this number not being exceeded. Now
my Invention consists in constructing them with three or more rows of

page_text: spindles. I thus economise both the cost of production, and the
original cost of the machinery, as well as the space it occupies. I do not
confine myself to any particular mode of driving the spindles, but for
the most part I adhere to the well known methods at present in
practice.
SPECIFICATION. in pursuance of the conditions of the Letters Patent,
filed by the said Weston Grimshaw in the Great Seal Patent
Office, on the 27th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WESTON GRIMSHAW, of Mossley, in the County of Antrim, Ireland,
Flax Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of April, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Weston Grimshaw, Her special
licence that I, the said Weston Grimshaw, my executors, adminis-
trators, and assigns, or such others as I, the said Weston Grimshaw,
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 terin 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 "CERTAIN IMPROVEMENTS IN SLUBBING AND ROVING FRAMES FOR
PREPARING FOR SPINNING COTTON, FLAX, AND OTHER FIBROUS SUBSTANCES,"
upon the condition (amongst others) that I, the said Weston Grim-
shaw, by an instrument in writing under my hand and seal, 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 Weston Grimshaw, do hereby
declare the nature of my said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the drawing
hereto annexed, and to the letters and figures marked thereon, that
is to say:
My Invention relates to the machines commonly known as slubbing
frames and roving frames, both which machines, as is well understood,
are similar in their, nature and purposes, being employed in processes
preparatory to the spinning of fibrous substances. It consists in apply-
ing such a method of construction to them as to introduce into each
frame a greater number of spindles than usual, with compactness and
simplicity, by which means I am enabled to effect an economy in the
cost of production, as well as in the original cost of machinery, and in
the amount of space it occupics. According to the modes which have
heretofore been in practice, the spindles in such frames are arranged in
a continuous row, or more commonly in two parallel rows, as shown in
the annexed drawing at Fig. 1, which is a plan of part of a roving
frame, sufficient to exhibit the arrangement of the spindles marked
8, 8, 8, &c. Now, by my improvement, I cmploy three or more rows of
spindles, arranging then so with respect to one another, that the ends
or slivers may be brought to them in the most convenient manner
from the delivering rollers. Fig. 2, is a plan of part of a roving frame,
with three rows of spindles; and Fig. 3, is a vertical cross section of the
same. The same letters in both figures refer to the same parts, s, s, &c.,
being the spindles with their bobbins, b, b, &c.; f,f, the flyers; and r,
the front rollers. It will be seen that the spindles, as well as the
bobbins, are driven by the horizontal shafts h, h', and bevels wheels
v, v', communicating motion to the horizontal trains of toothed wheels
w, w, w', w', &c. I do not, however, confine myself to this particular
mode of driving, as it is evident that that kind of gear commonly known
as skew gear, would be conveniently applicable to the purpose, as
well as various other methods which might be adopted. In like
manner, I do not confine myself to three rows of spindles, as it may be
shewn that frames may be constructed with four or more rows; the
number, however, will be always limited by convenience or utility.

page_text: What I claim in the foregoing statement as being new, and of my In-
vention, is the construction, as described, of slubbing and roving frames,
with three or more parallel rows of spindles, instead of with two rows
or one row, as heretofore practised.
In witness whereof, I, the said Weston Grimshaw, have hereunto
set my hand and seal, the Twenty-sixth day of October, in the
year of our Lord One thousand eight hundred and fifty-three.
Signed in the presence of
Richard Howson,
of Manchester.
WESTON GRIMSHAW. (L.S.)
