IMPROVEMENTS ON CER- TAIN INSTRUMENTS OR MACHINES COMMONLY CALLED ROVING FRAMES AND SLUBBING FRAMES, USED FOR PREPARING COTTON WOOL FOR SPINNING
Year: 1831

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MILNE, of Shaw, in the Parish of Oldham, in the County of Lancaster, Cotton
Spinner, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirteenth day of July, in the second year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
John Milne, His especial licence that I, the said John Milne, my exors,
admors, and assigns, or such others as I, the said John Milne, my exors,
admors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS ON CER-
TAIN INSTRUMENTS OR MACHINES COMMONLY CALLED ROVING FRAMES AND SLUBBING
FRAMES, USED FOR PREPARING COTTON WOOL FOR SPINNING;" in which said
Letters Patent is contained a proviso obliging me, the said John Milne, by
an instrument in writing under my hand and seal, particularly to describe
and ascertain the nature of my said Invention, and in what manner the same
is to be performed, and to cause the same to be enrolled in His said Majesty's
High Court of Chancery within two calendar months next and immediately

page_text: after the date of the said recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Milne, do hereby declare the nature of my said Invention to consist in
shortening the spindles and separating the flyers therefrom, and fixing a wheel
upon each flyer in such machines as aforesaid, and giving to the spindles and
flyers a separate motion, whereby much of the vibration and consequent
unsteadiness of motion occasioned by the usual length of spindle with the
heavy flyer at the top of it is avoided, and other advantages obtained. And in
further compliance with the said proviso, I, the said John Milne, do hereby
describe the manner in which my said Invention is to be performed by the
following description thereof, reference being had to the Drawing annexed,
and to the figures and letters marked thercon (that is to say) :-
DESCRIPTION OF THE DRAWING.
:-
Figure 1 represents an end view in section, and Figure 2 a front view,
of part of a roving frame or machine used for bringing cotton wool into a
proper state to be afterwards spun by mules or throstle frames into yarn. In
these Figures all the ordinary parts of the machine have been omitted, except
such as were required to shew the position in which the improvements are
applied; thus, in Figure 1, the driving pulley and geering by which the motion
is conveyed to the front roller are only shewn by the pitch lines of the wheels;
and all parts appertaining to the motions in the machine with which tho
improvements were not concerned are omitted, with a view to better cluci-
dation. In Figures 1 and 2 similar letters are used to denote similar parts.
The framing is marked A, A, and the drawing rollers B, B. The roving is
tinted red in both views, and is conducted from the front roller through the
flyer in the ordinary manner, and thenco to the bobbin, as shewn in the
Drawing. But it will be remarked, that the flyer, instead of being sup-
ported as in machines hitherto constructed on tho top of the spindle, is
supported by a fixed part of the framing marked C, C, and which I therefore
call the flyer rails. The flyers thus supported are driven at a regular speed
from any convenient movement of the machine, for the purpose; and in the
arrangement here represented, the spur wheel D drives two flyers by means
of the pinions marked E, E, which aro fixed upon the flyers. The spur wheel
D is driven by bevil geer from the shaft F, which receives its motion from
the driving shaft of the machine. It will be observed that there is a notch
cut out of the shoulder of the flyer at W. I find this prevents the thread

page_text: breaking so often as without it. G represents the copping rail, which receives
the ordinary alternating motion, by means of a rack and pinion, as shewn
at H, in Figuro 1, the movement of the pinion being reversed at the requisite
period by the well-known application of the mangle wheel or other means.
G is the copping rail on which the spindles which carry the bobbins are
supported by the steps m, m, and the collars n, n, all which move up and down
with the copping rail. The spindles in this arrangement receive their motion
from the shaft I, by means of the bevils, as shewn in the Drawing. The
shaft I is driven at an adequate speed by means of a strap and cone placed on
the driving shaft K, which cone is regularly traversed (in the ordinary manner)
so as to compensate for the filling of the bobbin, which necessarily requires
to be drawn slower as it fills, the front roller delivering at all times alike,
supposing the speed of the first mover to be always the same. The speeds of
the flyers and bobbins must of course be regulated according to the work to
be performed in any of the well-known methods now in use, which may be
applicable to the machine either as a roving or slubbing frame.
Now whereas I claim as my Invention a flyer detached from the spindle
with a wheel fixed upon it to give it motion, by which means the flyer may
be more effectually supported, and the spindle considerably shortened; an
arrangement which overcomes, in a great degree, the ordinary vibration of the
flyer, gives great facility to doffing and changing the bobbin, and enables
the improved machine to be driven at a greater speed than one on the ordinary
construction. And such my Invention as applied to roving frames and
slubbing frames being, to the best of my knowledge and belief, entirely new
and never before used within that part of His said Majesty's United Kingdom
of Great Britain and Ireland called England, His said Dominion of Wales,
or Town of Berwick-upon-Tweed, I do hereby declare this to be iny Specifi-
cation of the same, and that I do verily believe this my said Specification
doth comply in all respects, fully and without reserve or disguise, with the
proviso in the said herein-before in part recited Letters contained; where-
fore I hereby claim to mantain exclusive right and privilege to my said
Invention.
In witness whereof, I, the said John Milne, have hereunto set my hand]
and seal, the First day of September, in the year of our Lord One
thousand eight hundred and thirty-one.
JOHN MILNE. (L.S.)
