Year: 1861

page_text: LETTERS PATENT to John Platt, of Oldham, in the County of Lancaster,
Mechanical Engineer, and John Buckley, of the same Place, Overlooker,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS."
PROVISIONAL SPECIFICATION left by the said John Platt and John
Buckley at the Office of the Commissioners of Patents, with their
Petition, on the 20th July 1861.
We, JOHN PLATT, of Oldham, in the County of Lancaster, Mechanical
Engineer, and JOHN BUCKLEY, of the same Place, Overlooker, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS MATERIALS," to be
as follows:-
Our Invention relates to apparatus whereby the winding-on screw is regulated
by automatic means according to the increasing size of the cop, this end
being attained by using the shaper for determining the rate at which the said
screw shall traverse the nut. In carrying out our Invention we employ the
governing chain of the faller and band connected therewith for bringing a pinion
which is driven from any convenient part into a position from which it may
pass into gear with another pinion connected to the winding-on screw, but it
is prevented from engaging therewith until permitted to do so by an inclined
plane connected to the shaper.
Also, we cause the governing chain of the faller to be wound up by the
shaper so as gradually to raise the parts which act upon the band.

by the said John Platt and John Buckley in the Great Seal Patent
Office on the 20th January 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
PLATT of Oldham, in the County of Lancaster, Mechanical Engineer, and
JOHN BUCKLEY, of the same Place, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of July, One thousand eight hundred
and sixty-one, in the twenty-fifth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto us, the said John Platt and John
Buckley, Her especial license that we, the said John Platt and John Buckley,
our executors, administrators, and assigns, or such others as we, the said
John Platt and John Buckley, our 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 FOR SPINNING AND DOUBLING COTTON
AND OTHER FIBROUS MATERIALS," upon the condition, amongst others, that we,
the said John Platt and John Buckley, by an instrument in writing under
our hands and seals, (or under the hand and seal of one of us) should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Buckley, do hereby declare
the nature of our said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings (that is to say) :—.
Our Invention relates to apparatus whereby the winding-on screw of mules
is regulated by automatic means according to the increasing size of the cop.
In the accompanying Drawing Fig. 1 represents a portion of a mule in elevation
and Fig. 2 is a plan view thereof. The winding-on" quadrant" is shewn at
a, and the axis thereof at b. At c is the radial arm which carries the ordinary
screw for traversing the nut to which the winding-on chain is attached. At d
is a lever turning upon a fixed centre at e, and weighted at f, so that its
tendency is to turn downward. It is however upheld, excepting at certain
intervals, by two catches g, h, which extend as shewn in the Drawing beneath

page_text: a pin i projecting from the said lever d. The two catches g, h, turn upon a
centre at k; the latter of them is drawn under the pin i by means of a
weight, but the former retains the said position by its own gravity. The
lever & is provided with a pendant arm n, upon which is mounted a pinion o
situate above a pinion, which together with a pulley runs loosely upon a
stud r.
The pulley is provided with a band, which passes also over a
pulley s fixed to the ordinary shaft t, which carries the pinion for giving motion
to the winding-on quadrant a. The pulley 9 and pinion p therefore are con-
stantly driven whenever the usual motion is communicated to the draft t.
Beneath the pinion is also a second pinion u fixed upon a boss V, which
carries at its other end a bevel pinion W taking into another x, fixed upon
the winding or regulating screw; if therefore the pinion o be placed in gear with
the two pinions p, u, it acts as a carrier between them for conveying rotatory
motion from the former to the latter, and consequently to the regulating screw,
but if it be removed from that connexion, then the action on the regulating
screw will cease, although the pulley q and pinion p may continue to revolve.
Upon the quadrant a is fixed a projecting part y (shewn detached in two
views, Figs. 3 and 4) it consists of a series of steps arranged so as to constitute
an inclined plane in the direction of the axis of the quadrant and continued
partly around the axis thereof, the periphery of each step is however excentric
thereto, so that when the said quadrant is turned each of these steps acts as
a cam upon any part which may then be resting upon it. At z is a rod hinged,
by a compound joint at 1 to the lever d, and extending downward so as to
pass through a slot formed in a stationary plate 2. To this rod is attached a
chain 3, which after passing over a pulley 4 carries a weight 5, and by this
means the road is continually pressed inward so as to cause its lower end to
bear against a curved plate 5. This plate is formed at the end of a lever 6, turning
upon a fixed centre at 7, and connected at its other end to a rod 8, which is jointed
at 9 to the ordinary shaper bar 10. Upon the rod z is a projecting piece 11
extending above the inclined plane y. At 12 is the usual governor band
passing over a pulley 13, which pulley carries a tappet 14. The operation is as
follows:-Supposing the formation of a cop to be commencing, the governor
band 12 by causing the roller 13, to revolve, will bring the tappet 14 against
the tail end of the lever g, so as to cause it to turn upon its centre and remove
its upper end from the pin i, and the radial arm of the quadrant by turning
downward will operate by a set screw 16 against against the other lever / so as
to cause it also to turn upon its centre, and then the lever d will be free to fall,
this falling however is arrested by the arrival of the projecting part 11, in
contact with one of the steps constituting the inclined. plane y, and according

page_text: to the supposition that the cop is being commenced, the step so acting
will be that which forms the bottom of the incline, namely, at 18, Fig. 3.
By this operation the pinion o will have been brought nearly into gear with
the two pinions u, p; but will for the present be kept free therefrom; upon
the return motion however of the quadrant in the direction of the arrow, the
step of the incline being excentric to the centre thereof, will lower the stop 11,
so as to allow the pinion o to pass into gear with the two pinions p, u, and
the revolution of the shaft t will communicate rotatory motion to the pulley q
from thence to the pinion o, and through it to the pinion u, and thus the regu-
lating screw of the winding-on motion will be turned. A further motion of
the quadrant will bring a projecting piece 20, in contact with a stop 21 carried
by the lever d, which stop being thus forced forward will cause the said lever to
turn upon its centre so as to raise the pinion o out of gear with u, p, and then
the levers g, h, again falling under the pin i, the position of the parts shewn
in the Drawing will be restored, and thus the operation will continue for each
vibration of the quadrant. As the cop increases in size, however, it is neces-
sary that a less turning of the regulating screw shall take place, and for this
purpose the steps of the inclined plane are gradually moved forward so as to bring
them successively under the part 11. Suppose, for instance, that the said steps
are so moved forward that the most elevated receives the part 11 when it falls
then a similar motion to that above described will lower it so as to place the
pinion o into gear, but such lowering will take longer to effect, therefore the
pinions o, p, u, will be a shorter time in gear and less motion will be imparted
to the regulating screw, and after the same manner all intermediate stages of
the incline will effect a proportionate turning of the screw, and thus the
required variation for the winding-on will be effected. The advance of the
step incline is accomplished by the sliding of the shaper bar, which causes the
rod 8 to turn the lever 6 upon its centre, thereby shifting the position of the
curved end 5 so as to allow the rod z to be drawn inward by the weight 5,
thus bringing the part 11 gradually over a greater elevation of the incline.
The lever 6 carries a pin 25 situate within a slot formed in lever 26, turning
upon a fixed centre at 27 as the shaper bar advances in its usual operation, it
therefore causes the lever 26 to turn upon its centre 27, thereby altering the
position of an inclined plane 28; fixed thereon, at 29, is a roller carried by a
lever 30, the boss of which is prevented with another lever 31, to which a
chain 32 is attached, its other end passing over a ratchet wheel 33, after which
it passes to the usual governor lever, which acts upon the notched wheel, and
from thence to the faller. As the carriage runs out the roller 29 arrives in
contact with the inclined piece 28, and the levers 30, 31, are therefore caused

page_text: to turn upon their centre, thus pulling down the chain 32, and winding up the
governing chain and lever, and as the inclined plane 28 is altered as above
described, the extent of the said winding-up is determined by the shaper. When
the cop has arrived at its full thickness the chain 32 will have been so acted
upon as to have lifted the governor lever, so that it will no longer fall into the
notches, and thus there will no longer any action of the band 12, and the lever d
will consequently keep the pinions o, p, u, out of gear. In like manner during
the formation of the cop the band 12 ceases to act when the threads become slack
and the turning of the screw is not required; when also the cop is at its full
thickness the shaper bar will have advanced so that the lever 8 will have
passed the rail A by which it is supported, and the said lever will then fall
from the lever 6 to which it is connected by a pin 40. We have in the
above description alluded to the inclined plane formed by the steps as being
stationary in reference to the stop 11, but this arrangement may if desired be
reversed, the said incline having a traversing as well as a rotatory motion
imparted thereto, in which case the mechanism corresponding to the part 11
will not of course move sideways. We have also described the shaper as
the medium for determining which of the steps shall be in operation, but the
required relative positions of the incline and part 11 may be governed by
other moving parts of the mule from the motion of the radial arm, for instance,
which may be applied so as to traverse the said incline in order to bring
its several elevations into operation. We would also observe that it will be
evident the incline may be plain, that is, without steps, if desired.
Having thus described and ascertained the nature of our said Invention,
and the manner of carrying the same into effect, we desire it to be understood
that we claim as secured to us under the above in part recited Letters Patent,
the use of the shaper for determining the above-mentioned action of the
regulating screw of the winding-on motion.
Also, the use of the inclined plane for regulating the amount of motion
imparted to the regulating screw.
Also, causing the governing chain of the faller to be wound up by the shaper
so as gradually to arrest the action of the band 12.
In witness whereof, I, the said John Buckley, have hereunto set my
hand and seal, this Eighteenth day of January, in the year of our Lord
One thousand eight hundred and sixty-two.

CALLY. (L.S.)
