page_text: LETTERS PATENT to Roger Tatham, of Rochdale, in the County of Lancaster,
Mechanical Engineer, for the Invention of "IMPROVEMENTS APPLICABLE TO
MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS FOR
SPINNING."
PROVISIONAL SPECIFICATION left by the said Roger Tatham at the
Office of the Commissioners of Patents on the 18th April 1879.

"IMPROVEMENTS APPLICABLE TO MACHINERY FOR PREPARING COTTON AND OTHER
FIBROUS MATERIALS FOR SPINNING."
My Invention relates, firstly, to arrangements for cleaning the wire cards of
carding or scribbling machines. For this purpose I employ a roller armed with
needle points' card or other such apparatus situate above the centre of the cylinder
and doffer, and so arranged that it may be brought into contact with the surface
of either, or with that one of the ordinary carding rollers. This cleaning roller may
be mounted in any suitable frame to admit of its being turned or otherwise moved
into contact with any one of the above mentioned surfaces, and it may be driven
from any suitable revolving part of the machine. In connection with this clearing
roller I also adapt a creeper or receptacle for receiving the dirt which it removes.
By successively placing fresh carding rollers in the bearing contiguous to the
cleaning roller the whole series may be cleaned. In another arrangement I place
the cleaning roller between a carding roller and the taker in, so that the surfaces of
these two parts and that of the cylinder may be cleaned in the manner above
described.
In another arrangement I attach bearings to the feed end of the machine for
receiving successive carding rollers, between which and the taker in I adapt, when
required, the above mentioned cleaning roller to be used on either surface, as above
described.
Secondly. My Invention refers specially to that apparatus of preparing machinery
which is commonly called the coiler, but applicable also to other cams for receiving
the fibrous material, and consists in arrangements by the use of which a fresh cau

page_text: may be presented to receive the material when another has been filled. For this
purpose I cause the usual gearing which (in coilers) rotates the apparatus to impart
a slow motion to other gearing which moves a finger or other such part through a
certain space in a determined time, and when that has been done the said finger
causes the supporting plate for the can to move bodily so as to bring an empty can
into the position for receiving the material. For this purpose two or more cans may
be adapted to the supporting plate to be successively brought into the receiving
position, and the motion of the said plate may take place in a rotatory direction or in
a right line. Change wheels may be used for determining when a fresh can shall
be presented, and a knife or other suitable apparatus may be adapted for severing
the slivers between cans.
The above description refers specially to coilers, but my Invention may also be
adapted to other cans which receive fibrous material.

"IMPROVEMENTS APPLICABLE TO MACHINERY FOR PREPARING COTTON AND OTHER
FIBROUS MATERIALS FOR SPINNING."
My Invention refers to that apparatus known in the preparation of fibrous
material as the coiler, and by which the said material is delivered into cans which
are removed as they become filled, and consists in an arrangement by the use of
which fresh cans may be mechanically and successively presented to receive the
sliver when one has been filled, and I proceed to describe a method by which my
Invention may be practically carried out and by reference to the accompanying
Drawing, in which Fig. 1 represents a partial side view of the lower part of the
coiler apparatus, all the working parts being mounted on a foundation plate a from
which there extends the usual upright pillar b carrying the ordinary feed rollers and
revolving plate, which however are not shewn in the Drawing, they being of the
ordinary construction. Fig. 2 is a horizontal section of the apparatus taken about
the line A, B; Fig. 3, another horizontal view taken about the line C, D; Fig. 4, a
side view of the top of the pillar b; and Fig. 5, a plan view thereof. Instead of
using one can, to be removed by hand when filled, I use two or more mounted upon
a table c capable of turning upon a centre, and in the arrangement I am about to
describo two are employed. The aforesaid table c is mounted upon a centre d
carried by the foot plate a extending from the pillar b, and to it is attached a
toothed wheel e not turning upon its centre, but bodily fast with the table c. At f
is the usual shaft, which is enclosed within the pillar b, and to which rotatory motion
is communicated from the carding engine or other preparing machine in the
ordinary manner, and on the lower end of which is a toothed pinion g taking into
a wheel h which gears into another wheel i fast upon the circular disc k, which is
capable of revolving upon a stud / carried by the cable c, and by these means the
cane is caused to revolve in the well known manner. At F is a second can mounted
upon a second disc which is capable of turning upon another stud also extending
from the table c and provided with a toothed wheel ' corresponding to that shewu
at i, and the object is to bring these two toothed wheels i, i', alternately into gear
with the driving wheel h as the said cans become filled so as to avoid the necessity
of removing a filled can by hand and replacing an empty one by hand as is now the
practice. This is accomplished in the following manner-Upon the ordinary
shaft is mounted a pinion m in gear with a wheel n mounted on a stud, and fast
with it is a bevil p, in gear with another, the axis of which carries a worm q, taking
into a worm wheel r, the axis of which has another worm s in gear with a wheel t,
extending downward from which is a projecting pin u, situate in the same place as
a stud v, rising from a toothed wheel w, which is capable of being driven at certain
times by a wheel x on the ordinary shaft f, but at other times remaining stationary,
there being a few teeth removed at one part of its circumference, as seen at y. Fast
with this wheel is another gearing into the wheel 1, which is capable of driving at
certain times the wheel e fixed to the table c.
According to the positions of the parts as shewn the material is being delivered
into the can e and coiled in the usual manner, during which operation the ordinary
shaft drives the wheel t very slowly by means of the worms q, 8, and the finger u
is therefore gradually carried towards the stop v, and eventually it arrives in contact
therewith and moves it and the spaced wheel w forward until the teeth thereof and
those of the wheel x arrive in gear. This takes place when the can E has been filled,
the gearing being so arranged to suit the proper period of time and which may be
altered by changing the wheels to suit different requirements, and the said wheel to

page_text: therefore becomes driven by the shaft ſ, and by means of the wheels », 1, causes the
table c to turn upon its centre d and shift the filled can E into the position of that
shewn at F, to be removed by the attendant while the empty can F is turned into
the position of that shewn at E, there to be filled, by which time the spaced part y
of the wheel w will have regained the position shewn, and the said wheel w will
therefore cease to be driven. To register the position of the table c there is formed
on it a V part 5 which passes into a notch formed in a spring 6 carried by the foot
plate c. The table c carries an upright rod 7, on the top of which is a cam 8, which
when the said table revolves arrives against a sliding pin 9, which by being raised
acts against the cover 10 by means of a pin 11 extending therefrom, and by lifting
the said cover carries the ordinary bevil wheel of the usual rollers out of gear, and
thus stops the delivery, but when a fresh can has arrived in the position E the
elevation of the cam 8 has passed the pin 9 and the bevil of the rollers falls into
gear. On the upright rod 7 are horizontal blades 12, and each time a can is shifted
one of these passes through the sliver proceeding from the rollers and severs it. For
the performance of the above described operations and to enable the parts to recover
the positions shewn the stop v has of course to pass the finger u.
For this purpose
the said finger is mounted in the wheel w so as to be capable of sliding upward and
downward therein, and its bottom is formed as an incline, one side of the stop v
being of a similar form; when therefore the stop u has to pass it pushes up the
finger n, which afterwards fulls by its own gravity, and thus the starting point is
regained. In the Drawing the gearing is shewn uncovered for the purpose of
exposing the parts, but any suitable casing may be adapted. I have above described
the use of two cans, but three or more may be mounted on the table, the gearing
being modified to bring them successively into the position shewn at E, and instead
of the cans turning on a centre the table which carries them may be caused to move
to and fro in a right line.
Having thus described and ascertained the nature of my Invention, and the
manner in which the same is to be performed, I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent and for the
purpose above set forth, the use of a table for carrying two or more cans capable of
being shifted so as to replace each other by the revolution of the shaft for other
ordinary moving part of the machine.
In witness whereof, I, the said Roger Tatham, have hereunto set my hand
and seal, this Seventeenth day of October, in the year of our Lord One
thousand eight hundred and seventy nine..
