e, EDWARD
D'ORVILLE, of Manchester, in the County of Lancaster, Merchant, and Jonn
PARTINGTON, of Wicken Hall, near Rochdale, in the same County, Bleacher,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Nineteenth day of December, in the fourteenth year of Her reign,
and in the year of our Lord One thousand eight hundred and fifty, did, for
Herself, Her heirs and successors, give and grant unto us, the said Edward
d'Orville and John Partington, Her especial license, full power, sole privilege,
and authority, that we, the said Edward d'Orville and John Partington, our
exors, admors, and assigns, and such others as we, the said Edward d'Orville
and John Partington, our exors, admors, or assigns, shall 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, our Inven-
tion of "CERTAIN IMPROVEMENTS IN FINISHING THREAD OR YARN;" in which
said Letters Patent is contained a proviso, that we, the said Edward d'Orville
and John Partington, shall cause a particular description of the nature of
our said Invention, and in what manner the same is to be performed, to
be enrolled in Her Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters

page_text: Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with. the said proviso, we, the said
Edward d'Orville and John Partington, do hereby declare the nature of our
Invention of certain improvements in finishing thread or yarn to consist in the
construction and arrangement of certain machinery or apparatus by which
thread or yarn in a damp or wet state is stretched and dried in a state of
tension, by which process a superior finish is produced than by the process now
in common use; and the manner in which the same is to be performed and
carried into effect is particularly described and ascertained in the Drawings
hereto annexed, and the following explanation thereof; the scale to which the.
Drawings are made is marked thereon, and the same letter of reference
indicates the same part of the machinery in each view there represented.
Before we commence the description of the annexed Drawing we would
remark that this is a double machine; that is, yarn or thread are finished on
both sides, as will be herein-after described; but as the same letter indicates
the same part, the description will apply to either side, although it may be
more convenient to follow the description of one side of the machine only.
:
In the annexed Drawing, Figure 1 represents an end view, Figure 2 a side
view, and Figure 3 a plan, of one arrangement of our apparatus or machinery;
in these Figures, the letter A represents fast and loose pulleys, driven. by a
strap a; by the traverse of which, that part of the machinery which effects the
continuous motion of the yarn or thread when being submitted to the drying
process is put in motion or stopped in the ordinary manner. On the same
shaft which carries the pulleys A is placed the spur wheel B, geering into the
carrier wheel b, which drives the two opposite spur wheels C, C; these wheels
are respectively keyed on to the shafts d, d, passing the whole length of the
machine, and supported by pedestals on the framing, as represented in
Figures 2 and 3. At each end of the shafts d are keyed the metal rollers D;
which, when this part of the machine is in motion, necessarily revolve with
the shaft d; perpendicularly beneath the rollers D are placed similar rollers E,
keyed on to the shaft c, which is connected to the racks F, as shewn in
Figures 2 and 3. To the bottom of these racks F is fastened the table f¹,
which table, as well as the racks F, shaft e, and rollers E, are made to move.
up and down, being guided by the ends of the table f¹ and shaft e in the
perpendicular slots f, such motion being effected in a manner as will be
herein-after described. The pulleys G, best seen in Figure 2, set in motion
or stop that part of the machinery which relates to the stretching of the yarn

page_text: or thread while in a state of motion, which we shall now proceed to describe.
The pulleys G, shaft g', and pulley R are set in motion by the strap g. On
the pulley R run two straps, passing over the pulley 1 and 2, which pulleys
run loose on the shaft: The strap which runs on the pulley r is a straight
strap, and that which runs on the pulleya crossed one. The pulley is
made fast on the shaft, and it is evident that this shaft may be made to
revolve in contrary directions by traversing either the straight or the crossed
strap, as may be required, on to the fast pulley. On the end of the shaft
is keyed the bevil wheel J, gearing into the bevil wheel j, which is keyed on
the bottom end of the upright shaft k², on the top end of which shaft is keyed
the worm 1, gearing into the worm. wheel h, which is keyed on the shaft H,
as seen in Figures 2 and 3. On this shaft H are keyed the two pinions I, I,
gearing into the racks F. The handles and pare for the purpose of
traversing the two straps on the pulley R in the ordinary manner, best seen in
Figure 2. By this motion the rollers E are either raised or lowered in the
following manner :-The strap 9 being traversed on to the fast pulley G,
motion is given to the shaft g¹ and the pulley R, which, by means of the two
straps before mentioned,, causes the loose pulleys and to revolve in
.contrary directions. By moving the. handles o or p, as occasion may require,
one or the other of these straps is traversed on the fast pulley ; which
moves the shaft, bevil wheels J. and j, shaft k', and worm 1'; the worm
moves the worm wheel h, shaft H, and pinions I, which pinions elevate or
depress the racks F, as required; the shaft e and rollers E, being in connection
with the racks F, are thus elevated or depressed at the will of the operator.
Having described that part of the machinery which relates to the motion
and stretching of the yarn or thread, we shall now proceed to describe the
apparatus for drying it. K represents a stove for burning coke, which is
supplied as required at the door i, see Figure 1; L is the stove pipe, by which
the smoke and gas is conveyed away; 9 is a throttle valve for regulating the
draught; the handle N is connected by a rod q' to the stove K, supported by
wheels on the curved railway M; by moving the handle N backwards or
forwards, the stove k therefore may be made to approach to or recede from
the rollers D and E, as may be required. To allow of the traverse of the
stove K, the pipe L is made. to move freely in the coupling or joint.t, as seen
in Figure 2.
Having described the construction of one arrangement of our machinery or
apparatus, we shall now proceed to describe the mode of operating therewith
when finishing yarn or thread. Supposing, therefore, the stoves K to be heated,

page_text: the operator puts the machine in motion, by traversing the driving straps a and g
on to the fast pulleys A and G, and places a hank or hanks of yarn in a damp
or wet state round each pair of rollers D and E, as shewn by blue lines in the
Drawings, the lower rollers E having been previously raised by the traversing
of the crossed strap on to the fast pulley, so as to approach near to the
rollers D. As soon as the wet yarn or thread has been placed on the rollers
D and E, the operator moves the handle p, so as to traverse the straight
strap on to the fast pulley 3, thus lowering the bottom roller's E, as herein-
before described. When the rollers E have receded from the rollers D so far
as to stretch the yarn or thread, this acts as a strap, and causes the rollers E
to revolve at the same speed as the rollers D. Whilst this continuous motion
of the stretched yarn or thread is going on, the operator moves the handle N,
so as to bring the heated stove K close to the rollers D and E, on which the
hanks are placed, so that the drying process proceeds at the same time, and
the yarn or thread (when dry) is taken off the rollers D and E with a more
perfect finish, and free from all tendency to coil or snarl, which yarn finished in
the ordinary manner is subject to. The foregoing description of the annexed
Drawing will shew one arrangement by which our Invention may be performed
and carried into effect; but it will be obvious to mechanics and persons con
versant with work of this nature, that the arrangement of such apparatus or
machinery may be variously modified and varied, and yet produce the same
result; and it is also obvious that the requisite heat for drying may be
generated and arranged otherwise than we have described. We do not
therefore claim as our Invention the exact arrangement of apparatus or
machinery or means of heating herein set forth and described, nor do we
claim any separate or well-known part of such machinery; but we do claim the
finishing of damp or wet thread or yarn in a state of tension and of motion
whilst submitted to the drying process; and such our Invention being,
to the best of our knowledge, new and never before practised in that part of
Her Majesty's Dominions called England, we deliver this as our true and
faithful Specification of the same.
In witness whereof, we, the said Edward d'Orville and John Partington,
have hereunto set our hands and seals, the Seventeenth day of June,
in the year of our Lord One thousand eight hundred and fifty-one.
EDWARD (L.S.) D'ORVILLE.
JOHN
(L.S.) PARTINGTON.
