Year: 1873

page_text: LETTERS PATENT to John Nasmith, of Manchester, in the County of
Lancaster, Mechanical Engineer, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS
FOR SPINNING."
Scaled the 19th August 1878, and dated tho 22nd February 1878.
PROVISIONAL SPECIFICATION left by the said John Nasmith at the
Office of the Commissioners of Patents, with his Petition, on the
22nd February 1878.
.
I, JOHN NASMITH, of Manchester, in the County of Lancaster,
Mechanical Engineer, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER
FIBROUS MATERIALS FOR SPINNING," to be as follows:—

page_text: portions of fibrous material, and impurities which may cling to the
taker-in are opened and cleansed. For this purpose I place beneath
the feed rollers a row or rows of -needle points in contact or nearly so
with the surface of the said taker-in, when therefore the material arrives
in contact with these points it undergoes a combing action by which it t
is opened and cleaned.
"
Scoondly. My Invention consists in causing the stop motion of
drawin frames to come into operation when knotty or thick places
occur in the sliver as well as when it breaks. For this purpose I use
the ordinary trumpet piece drawn down by the tension of the sliver 1
against a weighted lever, and on a breakage taking place the motion of
the machine is arrested as usual. When knotty or thick parts arrive at
the trumpet their obstruction causes it to be pulled downward against
the weighted lever above mentioned whereby a part is brought in contact
with the usual vibrating or revolving apparatus, and the motion of the 1
machine is arrested.
•
Thirdly. I apply to the orifice of the trumpet an adjustablo pieco
which may be caused to increase or decrease the aperture. For this
purpose I use a pin extending through a boss and capable of being with-
drawn from or passed for any required distance into the orifice through 2
which the sliver passes, and of being held there by a tightening screw.
On the end of this pin I form a rounded groove which forms a curve
for gradually guiding the sliver.
.
SPECIFICATION in pursuance of the conditions of the Letters Paten
filed by the said John Nasmith in the Great Seal Patent Office 25
on the 22nd August 1878.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
NASMITH, of Manchester, in the County of Lancaster, Mechanical
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 30
Patent, bearing date the Twenty-second day of February, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, givo

page_text: Firstly. To the carding engine, and consists in the adaptation thereto.
of an instrument of a certain construction whereby lumps or entangled
portions of fibrous material and impuritics which may cling to tho
taker-in are opened and cleansed. For this purpose I place beneath tho
feed rollers a row or rows of needle points which act as a comb. ;
In the accompanying Drawing this part of my Invention is shown at
Fig. 1, in which the taker-in is shown at a and the feed rollers at 6,
beneath which is a bar o carried by a bracket extending from the framó- .
work, and having fixed thereto a plate & the outward edge of which is:
furnished with a series of needle points e, as seen in Fig. 2, which points.
may be attached by soldering or-by other convenient means. When the
material arrives in contact with theso points it undergoes a combing
action by which it is opened and cleaned, tho said points allowing tho
fibres to bo pulled through them, but preventing the passage of seeds,
leaf, or dirt, such impurities falling along the surface of tho plato d.

page_text: The second part of my Invention is shown at Figs. 3 and 4; the former
of which represents a portion of a drawing frame with its stop motion
in cross section and the latter in front view. The usual callender rollers
are at f, above which is the trumpet & balanced on the knife edge and
provided at its other end with the jointed filling picco i situate above i
the constantly revolving tappet wheel j mounted on the shaft k, which
is driven from the back stop motion shaft in any convenient manner.
The filling piece is provided with a projecting part 2 which extends
under a lever m capable of turning upon a centre n and having a pro-
jecting part o which is situate over a second revolving tappet wheel j* 1
mounted on the shaft k, the said lever resting upon a stop z and weighted
as required, according to the thickness of the sliver. The trumpet g
is retained at the proper distance from the callender roller by tho
weighted lever m balanced by a weight p. During the operation of the
machine should a sliver break the trumpet being no longer drawn
down thereby will turn upward, and the filling pieces will fall within
rango of the tappet wheel j, whereby the part will be forced against
the frame g and act as a stop for arresting the motion of the machine
in the well known manner, and thus far the operation is that commonly
in uso; but supposò that a thick or knotty portion of sliver should enter
the trumpet, then according to our Invention the extra friction thereon
will pull it downward, and by turning it upon the knife edge h will
elevate the filling piece, the part thereof acting on the weighted
lever m, the extra friction of the sliver will overcome the weighted
lever m and will cause it to turn upon its centre » and bring the pro-
jocting part o within range of the tappet wheel je, and the said part o
thus acting as a stop will cause the motion of the machine to be arrested
as in the former case.
Fig. 5 shews in section, and Fig. 6 in plan view, a modification of
this part of our Invention. At g is the trumpet which in this instance
rests by means of a part r upon the frame q and is provided with a knife
edge & capable of turning upon a weighted lever t, which also has a
knife edge capable of turning upon a fixed part 10. The lever t is
formed with an orifice through which a lug of the trumpet piece g
extends, and to this lug is jointed the filling piece i.
The operation is as follows:-When the machine is at work the
several parts are in the positions shown, the trumpet is held against

page_text: the frame g at the point and its ordinary centro e upon the weighted
lover, and the tension of the sliver is drawing downward the trumpet
against tho weight of the lever at this time provented from rising
beyond a certain distanco by a cross bar w. Should a sliver break then
the above mentioned balance is destroyed and the weight of the filling
picco i will cause the trumpet piece to turn upon the centro s and the said
filling picco will arrive within the range of the tappet wheel j, whoroby
the motion of the machine will be arrested as usual. Suppose a knotty
place in the sliver to arrive at the trumpet, then the increased power
exerted by the sliver will drag the trumpet downward, causing it to
turn upon the point and depress its ordinary centre & by moving the
lever t, and thus the filling pieco i will be brought within rango of tho
tappot wheel j.
Another part of my Invention relates to the orifice of the trumpet
of the stop motion, and consists in applying an adjustable picco which
may be caused to increase or decrease the aperture; this is shown at
Figs. 7 and 8, in which 7 represents the trumpet with a boss to through
which is an aperture for the reception of a pin a which may be adjusted
inward or outward and maintained in any required position by means of
a set scrow y. The inward end of this pin is formed as a rounded groove
which forms a curve for gradually guiding tho sliver, and by adjusting it
inward or outward tho orifico may be regulated as desired..
Having thus described and ascertained the nature of my said In-
vention, and the manner in which the same is to be performed, I
3 desire it to bo understood that I claim as secured to me under the
abovo in part recited Letters Patent and for the purposes above set
forth,-
Firstly. As applied to carding engines the use in conjunction with
the taker-in of an instrument of the character of that shewn at Fig. 1.
Secondly. As applied to the stop motion of drawing frames I claim
the use of additional parts, substantially as described and brought into
action when thick or knotty places occur in the sliver, thereby arresting
the motion of the machine.

to the thickness of the sliver.
In witness whereof, I, the said John Nasmith, have hercunto set my
hand and scal, this Twenty-first day of August, in the year of
our Lord One thousand eight hundred and seventy-three.
