CERTAIN IMPROVEMENTS APPLI- CABLE TO DRAWING AND SLUBBING FRAMES USED IN THE MANUFACTURE OF COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Jonn
HOULDSWORTH, of Glasgow, in the County of Lanark, 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 Ninth day of December, in the sixth year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said John
Houldsworth, His special licence that I, the said John Houldsworth, my
exors, adors, and assigns, or such other as I, the said John Houldsworth,
my exors, adiñors, 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, an Invention, communicated to
me by a certain Foreigner residing abroad, of "CERTAIN IMPROVEMENTS APPLI-
CABLE TO DRAWING AND SLUBBING FRAMES USED IN THE MANUFACTURE OF COTTON
AND OTHER FIBROUS SUBSTANCES;" in which said Letters Patent is contained a
proviso obliging me, the said John Houldsworth, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature of
the said Invention, and in what manner the same is to be performed, and to

page_text: cause the same to be enrolled in His said Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said
Letters Patent, as in and by the same; reference being thereunto (unto) had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Houldsworth, do hereby declare that the nature of the said Invention
consists in the application and adaptation of certain machinery or apparatus to
drawing and slubbing frames used in the manufacture of cotton and other
fibrous substances, for the purpose of stopping the action of such machines so
soon as any one or more end or ends of cotton or other fibrous substance shall
break or cease to be supplied to the machine; and the manner in which the
same is to be performed and carried into effect will be seen by reference to
the annexed Drawing and the following description thereof.
In this description it will remarked that any part of the machinery which is
referred to by a letter of reference is indicated by the same letter of reference
in each of the various views and sections where such part is represented.
In the Drawing, Figure 1 represents a front view, and Figure 2 an end
view of one description of drawing frame used in the manufacture of cotton,
to which the improvements are applied; and Figures 3, 4, and 5 are views
and sections on an enlarged scale of the apparatus or machinery in which the
improvements consist. In Figures 1 and 2, A represents the driving pulley
of the machino which receives motion from any adequate power; and B is a
strap or belt conveying motion to the fast pulley b or to the loose pulley U¹,
according to the position in which it is placed by the strap guider C. The
drawing rollers and various other parts of the machine which are common to
ordinary machines of this class, being no part of the Invention, require no
particular description. In Figures 1 and 2, a represents a series of-guides-
through which the sliver of cotton or other fibrous material is passed previous
to its arrival at the drawing rollers. These guides a are respectively supported
on small studs, on which they vibrate in the direction indicated by dotted lines
and an arrow at Figures 2 and 5. D is a shaft supported at each extremity,
and passing along the back of the drawing frame. This shaft D is allowed
to revolve freely, and is provided with a rib or midfeather d on one side and
a projection or finger piecé e on the other side, and the relative position of
these parts & and e will be best scen on an enlarged scale at Figures 4 and 5.
Returning to Figures 1 and 2, E represents a horizontal lever moving on its
fülerum at f, one extremity of which lever is 'connected with the strap guider
C, and the other held and guided by forks a proceeding from the under sido

page_text: of. the sliding.rod F, as best seen in the detached parts represented at Figures
8 and 4. The traverse or end motion of this sliding rod F is indicated by
dotted lines, and the spiral spring g with which it is provided gives it a constant
tendency to move in the direction of the small arrow towards the point
indicated at g. The opposite end of the rod F to that at which the letter g¹
is placed is returned or has a small projection, as seen at Figures 3 and 4,
whero represents a spring catch pressing in a notch on the slide rod F, and
holding it in the position there represented; but as soon as this spring catch h
is forced back, and the slide rod F relieved, the spiral spring 9 carries it to the
point indicated at.g', and consequently vibrates the lever E in the direction of
the arrow and dotted lines at its extremity at Figure 4.
Having described the property and action of the various parts in which the
improvements consist, together with the position and manner in which they
are applied to one description of drawing frame, I shall now proceed to
describe the effect of their combined action, by means of which the machine is
stopped so soon as one or more end or ends break or cease to be supplied to
the drawing frame. Supposing, therefore, the driving strap B placed on the
fast pulley b, as represented at Figure 1, and the machine to be in action, a
regular supply of cotton or other fibrous substance will be drawn forward
through the respective guides a by the action of the drawing rollers, and this
constant drawing action of the cotton or other substance will by its friction
draw forward the series of guides a to the bearings, as seen at Figures 1, 2, 3,
and 5. But supposing ono of the ends to break, or the supply of cotton or
other fibrous substance to cease, the guide through or over which such end
passes to the drawing rollers being no longer held up by the friction of such
end, will, by its gravity, vibrate or fall to the position shewn in dotted lines at
a, Figures 2 and 5. In this position the opposite end of the guide a to that
at which the cotton or other fibrous substance had passed through, strikes
against the midfeather or rib d, and revolves the shaft D to a position in
which the projection or finger piece e strikes against the spring catch h, and
forces it back, as represent in dotted lines at Figure 5. The slide rod F
being relieved by the spring h, which is thus forced out of the notch, the
spiral spring g immediately forces the rod F to the point g', as seen in dotted
lines at Figures 1, 3, and 4, and vibrates the horizontal lever E to the position
indicated in dotted lines at E' in Figure 4. The strap guider C, being thus
carried by the lever E with which it is connected, will traverse the strap B
from the fast pulley 6 to the loose pulley 6', and stop the machine, as required.
It will also be seen, by referring to Figures 1 and 3, that there is sufficient

page_text: space between the forks a, x, or projections from the rod F to vibrate the
lever E by hand when required, and thereby traverse the strap. B,.into the
loose pulley, and stop. the machine. But when the machine is in action, and
all the ends up, the rod F must be placed by hand in the position seen in
Figures 1, 3, and 4, and the lover E.in the position to keep the strap B on
the fast pulley where it is held by a small swell in the fork on the under
side of the rod F, as seen at Figures 1 and 3.
From the foregoing description the advantages arising from the application
of these improvements to drawing frames used in the preparation of cotton for
spinning (inasmuch as the machine requires less attendance, and stops as soon
as an end breaks or the supply ceases) will be readily seen by spinners and
persons conversant with the subject; and although the application of the
improvements to other drawing and slubbing frames may require some varia-
tion in the construction and arrangement of the parts, yet such variation and
arrangement must greatly depend on the build and construction of the machine
to which the improvements are to be applied, and will be readily effected by
any competent mechanic.
Having now described the nature of the improvements, and the manner in
which the same are to be performed and carried into effect, together with the
mode of applying the same to one description of drawing frame, I wish it to
be understood, that I do not claim any of the separate or well-known parts of
such machines or apparatus. But I do claim the construction and arrangement
of apparatus or machines set forth and described at Figures 3, 4, and 5, of the
Drawing, as applied to drawing and slubbing frames used in the manufacture of
cotton and other fibrous substances, for the purposes already explained. And
I further claim any modification of such Invention by which the friction
arising from the motion of the cotton_or_other-material-supplied-to drawing
and slubbing frames used in the manufacture of cotton and other fibrous
substances may be made to support a lever, weight, or other implement,
which lever, weight, or other implement shall cause the machine to stop so
soon as the friction or support of such cotton or other fibrous substance shall
cease to exist. And which Invention having never before, to the best of my
knowledge and belief, been 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 my
Specification of the same, and that I do verily believe this my said Specifica-
tion doth comply, in all respects; fully and without reserve or disguise, with the
proviso in the said herein-before in part recited Letters Patent contained;

page_text: wherefore I hereby claim to maintain exclusive right and privilege to the said
Invention.
In witness whereof, I, the said John Houldsworth, have hereunto set my
hand and seal, the Thirty-first day of May, in the year of our Lord
One thousand eight hundred and thirty-six.
