Year: 1861

page_text: LETTERS PATENT to Hugh Mason, of Ashton-under-Lyne, in the County
of Lancaster, Cotton Manufacturer, for the Invention of "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON OR OTHER
FIBROUS MATERIALS."
Sealed the 10th December 1861, and dated the 12th June 1861.
PROVISIONAL SPECIFICATION left by the said Hugh Mason at the
Office of the Commissioners of Patents, with his Petition, on the 12th
June 1861.
I, HUGH MASON, of Ashton-under-Lyne, in the County of Lancaster, Cotton
Manufacturer, do hereby declare the nature of the said Invention for "IM-.
PROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON OR
OTHER FIBROUS MATERIALS," to be as follows:-
My said improvements relate, firstly, to an improved stop motion for the.
drawing frame. When the sliver breaks in its passage from the rollers the
trumpet through which, if not broken it would pass, is so balanced that in
the absence of the sliver it falls back and acts upon a catch in communication
with the stop motion and stops the frame. And also when a snarl or lump
is formed and cannot pass through the trumpet, the same effect of stopping
the frame takes place. The said arrangement has the effect of an additional
singling motion, because when the ordinary motion fails to act the frame will
be stopped as already described.

page_text: Secondly, to improvements in rollers with loose bosses working upon fixed
spindles instead of allowing them lateral motion as hitherto adopted, which
has the injurious effect of cutting or wearing into the sides of the bearings.
I make a collar or swell on that part of the spindle next to the cap. The
loose boss is countersunk at each end or has an internal shoulder, the effect
being that if the rollers should be set out of line the bosses will not work
outwards towards the cap.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Hugh Mason in the Great Seal Patent Office on the
12th December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HUGH
MASON, of Ashton-under-Lyne, in the County of Lancaster, Cotton Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of June, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Hugh Mason, Her special licence that I, the said Hugh
Mason, my executors, administrators, and assigns, or such others as I,
the said Hugh Mason, 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 OR APPARATUS FOR PREPARING AND SPINNING COTTON
OR OTHER FIBROUS MATERIALS," upon the condition (amongst others) that I, the
said Hugh Mason, my executors or administrators, 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 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 Hugh Mason, 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 ful-
lowing statement (that is to say) :-

page_text: This Invention relates, firstly, to an improved stop motion for the drawing
frame. The trumpet through which the sliver passes from the drawing rollers
to the can or coiler is placed upon pivots and nicely balanced, so that when
the sliver is absent from roller lap, breakage, or other cause, or when a snarl
or lump is formed the trumpet falls back and acts upon a catch or lever in
communication with the stop motion and stops the frame.
Secondly, to improvements in rollers with loose bosses working upon fixed
spindles. Instead of allowing them lateral motion as hitherto adopted, which
has the injurious effect of cutting or wearing into the sides of the bearings,
I make a collar or swell on that part of the spindle next to the cap. The
loose boss is countersunk at each end or has an internal shoulder, the effect
being that if the roller should be set out of line the bosses will not work
outwards towards the cap.
The first part of this Invention will be clearly understood by referring to
the figures and letters on the accompanying Sheet of Drawings; the second
part being so plain and simple as to require no further description or illus-
tration.
Fig. 1 is a transverse section of a plunger drawing frame having one arrange-
ment of my improved stop motion; Fig. 2 an end view of the balanced'
trumpet and parts connected with it, drawn about full size; Figs. 3 and 4
are end views of modifications of the same, and Figs. 5, 6 & 7, represent
other modes of balancing the trumpet, and Fig. 8 is a transverse section of
part of a coiler drawing frame having one arrangement of my improvements
attached.
In Fig. 1, a is one of the end frames of the machine; b, 'the drawing
rollers; c, the ordinary eccentric shaft for the singling motion, and d, the
calender rollers placed in an angular position. In Figs. 1 and 2, the trumpet
through which the sliver passes to the can is shewn at e, it is weighted by
an arm or projection f, provided with pivots g, and extending below the
table as at h. The pivots g form part of a small block, fitting a slot i, having
through it a screw so that the positions of the pivots may be adjusted and
balance the trumpet in such a manner that when the sliver is passing through
it the end h will be raised, and when the sliver is absent or when the trumpet
is pressed by a snarl the end h will be lowered as shewn by the dotted lines.
Below the arm or projection f there is an additional rocking shaft k having
fixed to it the lever and another lever m. On the ordinary eccentric shaft c
there is a lever n, Fig. 1, connected by the rod o to the lever m, so that
when the eccentric shaft moves to and fro the additional shaft k moves in
the same manner, and if the shaft is held the eccentric shaft is held also.

page_text: The lever vibrates to and fro clear of the end h of the arm f when the
trumpet is raised by the sliver, but is held by the arm when the trumpet
falls back and acting on the eccentric shaft stops the frame. The notched
part of the top of the lever comes in contact with the aforesaid arm, but
the tongue part raises the trumpet to its working position when the lever
moves back. In order to prevent the sliver from lapping on the calender
rollers there is a guard p consisting of a piece of felt or other suitable material
fastened to a plate fixed to the small frame q. Fig. 3 represents a balance
trumpet having at the bottom of the arm fa recess or indentation r, and
the lever on the additional shaft is pointed at the end as at s; the said
lever moves freely to and fro when the sliver is passing through the trumpet,
but enters the recess, and is held fast when the trumpet falls back and stops
the frame. Fig. 4 represents a balanced trumpet having a projection t at
the bottom of the arm f, and the lever on the shaft k has two tongues
or lifters so that after the lever has been held and the frame stopped
tho trumpet shall be raised by the lever as it moves either backwards or
forwards.
Figs. 5, 6, and 7, represent a few of the many modified arrangements
which can be employed for balancing the trumpet. In Fig. 5 the pivots g
are fixed to the shoulder v, having a screwed arm w, to the other end of
which is jointed a pin a, which passos through a hole in the table above
the rocking lever 1, so that when the trumpet is raised the pin is above the
lever, but when the trumpet falls back the pin is lowered and coming in
contact with the lever holds it and stops the frame. On the screw w there
is the nut y, which is shifted to the exact position required for balancing the
trumpet. In Fig. 6 the trumpet is balanced by screwing in or out the
plug z, and in Fig. 7 the same effect is produced by placing the pivots g of
the trumpet upon a shoulder a¹, acting as a nut, into which is screwed tho
arm b¹ carrying the pin x, so that by screwing the arm in or out of the nut
the weight will be adjusted as required. Each of these improved arrangements
not only prevents the formation of waste, but has the effect of an additional
singling motion, because when the ordinary singling motion fails to act the
frame will be stopped as before described. In many cases it may be found
advantageous to use this additional rocking shaft only, dispensing with the
ordinary eccentric shaft, in which case the said additional shaft will be
required to have an eccentric or other well known stopping motion in con-
nection with it. The same effect may be produced if the additional shaft
is caused to revolve instead of vibrate. The aforesaid arrangements may be
applied to a coiler drawing frame with equal facility. The position of the

page_text: trumpet is changed to suit the altered position of the calender rollers, and
the projecting arm made of any desired form and length, care only being
required to make the trumpet exceedingly sensitive by nice balancing, so
that when the trumpet is held by the sliver in its passage no stoppage shall
take place, but when the trumpet is relieved the projecting arm comes in
contact with the lever on the additional rocking or revolving shaft and stops
the frame.
Fig. 8 represents a transverse section of a coiler drawing frame. a is one
of the end frames of the machine; b, the drawing rollers; c, the ordinary
eccentric shaft; d, my additional rocking or revolving shaft, and e, the calender
rollers, above which are placed the trumpet f balanced as required on the
pivots g, so that when the sliver is absent from the trumpet the lower end
of the arm h can come in contact with the lever i on the shaft d, and hold it
so as to stop the frame either by connecting it by the levers j, k, and rod
with the ordinary eccentric shaft, or if used singly by an eccentric or other
well known stopping motion at the end of the shaft d.
Having now described the nature and particulars of my Invention, and
the manner in which the same is to be performed, I desire it to be understood
that I claim, the improvements in machinery or apparatus for preparing
and spinning cotton or other fibrous materials as such are herein described and
illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Hugh Mason, have hereunto set my
hand and seal, this Tenth day of December, in the year of our Lord
One thousand eight hundred and sixty-one.
Signed, sealed, and delivered by the
within-named Hugh Mason, in
the presence of
G. SEPTIMUS HUGHES,
17, Cross Street,
Manchester.
