NEW PATENT ROPE YARN SPINNING MACHINE.
There is now in Lodge-lane, Toxteth-park—a very delightful
locality in the neighbourhood of the town—new and interesting
works for the making of ropes, cables, &c., from both Russia
and -Manilla hemp, recently established by Messrs. Hutche-
son and Jarvie, and in which the yarn spinning machine is
on the principle patented by Messrs. Craig and Jarvie, of
Glasgow, and the only one at work in the kingdom. We
were, on Saturday, politely shown through the works, and
were much gratified by witnessing the whole of the opera-
tions, from the spreading of the raw material to the comple-
tion of the process--which is accomplished in a much shorter
space of time than by the ordinary mode, while the yarn
produced is more even and perfect. The entire machinery
is driven by a handsome steam-engine of twenty horse-power
in a detached building ; and there is a covered rope-walk,
on a dead level, laid with lines of railway, and upwards
of 100 fathoms in length. The machinery for preparation
is on the same principle as that in use in most of our
improved roperies ; but it is finished in a superior manner--
having all the nicety and brightness of a piece of clock-work.
It resembles, in operation, the machines employed
for a
parallel purpose in cotton factories—particularly in its
throwing off the material in roves, or " slivers," into cans
placed on the ground to receive it. The hemp first passes
through the " spreading machine," over sliding or dropping
bars, armed with teeth like heckles, and revolving on endless
brass chains, passing round two internal rollers. The roves—
three in number—are passed on these heckles, uncler a
large roller covered with strong leather, and from which,
finely equalized, it falls softly into the cam The hemp,
before being subjected to this first process, is weighed out
in half-pounds ; and the machine is fed by a girl, who,
to give it an equal supply, is I guided by an indicator,
with a clock face, the movement of which accommodates
itself to the velocity of the work for -the time being. The
roves are then taken to the " spinning frame," in which
the principal novelty of the inventors consists; and which is
a most ingenious piece of mechanism, admirably adapted for
producing a smooth, even. and glossy thread, or yarn—the
grand desideratum in rope spinning. The carriage is the same
in the first working part as the spreading-carriage; and the
roves, after passing over tha dropping-needles, or slides,
and also under a longer roller, are drawn through a horizontal
range of metallic taps, or tubes, the outer part formed of
two pieces, the upper one of which, by means of a spring,
forms a nipper, and answering, in pressing and attenuating the
yarn, the fingers of the operator in the ordinary manlier of
spinning from a fibrous substance. Continuous with this
spinning-nipper is another tube, split, as it were, in two, with
the upper part moveable, 'and pressed down with an equal
force by a small lever, to the end of which a weight is at-
tached. This tube is lined with a rag of any sort of woollen
cloth, as a smoother; and the yarn is drawn from it in a
perfect state, and much more equal and glossy than by hand;
the film, or bristles, of the staple thrown out by the centri-
fugal force in twisting, after the hand, has left it, in
bobbin and fiy-spinning being almost wholly obviated.
The spinning-machine produces 8 threads simultaneously,
from a many roves; and accomplishes, with but three per-
sons to attend it (one of them a female) as much within a
given time as could be spun by sixteen men. The carriage
that draws out the thread moves along the railway in precise
unison with the velocity of the spinning, and the delivery.
The four wheels of the carriage are, by an ingenious applica-
tion, put in motion by connection with the machinery, so that
it runs along to meet every emergency—having sufficient hold
of the rails by its own weight. A ground rope, or a wheel
running on a toothed rack (beth inconvenient) are, therefore,
dispensed with. After 100 fathoms are spun, (of six yarns
simultaneously), the whole is wound upon a common large
warpet's reel at the further end of the shed, whence it is taken
off in " hauls," or large hanks, and is then ready either for
tarring, if it be for ships' use, or for at once being formed
into strands for white rope. The speed at which the spinning
machine may be worked is almost unlimited. The steam was
not well up when we saw it; but eight fine yarns of Manilla
hemp, each of 100 fathoms in length, were spun by it in less
than six minutes. The tarring machine on the works is on
the best principle. For the information of the uninitiated, we
may state that the usual portion of tar put into ropes for ships,
is about a fifth part of the weight of the rope when completed,
or one fourth of the yarn before it is added. When the yarn is
spun, the " the haul" is taken from the further end of the
shed to another large warper's reel at the other, and is
wound upon large bobbins placed on horizontal spindles, and
turned by the engine. When the bobbins are filled, a num-
ber of them, proportioned to the size of the rope required,
are put into a framework called "the bobbin bank." The
yarns are then passed from them through the " register
plates,"—iron plates perforated in circles for forming:the
strands, and thence through iron tubes, so contrived that
each thread in the respective strand, when twisted, has
an equal tension on being put to the strain. This is a
great improvement on the old fashion, by which all the
threads in a strand were of equal length. stretched
out, and compacted by twisting. it followed that the
centre threads were but twisted:in nearly a straight line,
while those outside had, in the completion of the opera-
tion to "go the round" all along, like a cork-screw. A
strain put on a rope made in this way inevitably fell almost
exclusively on the outside yarns of each strand, and
these would break first, before the interior yarns were
put to much stress. By the present plan an equal tension is
put, a priori, upon every thread. The apparatus for laying
the strands is as efficient and rapid in its operation as the'
other parts of the machinery, and is worked with great faci-
lity. It will lay two ropes at a time. The roles produced,
from best bower cables to clothes-lines, are beautifully per-
fect, and have a glossy and silky appearance, which we have
never seen equalled at any other manufactory. Notwith-
standing the " expertness "' of the machinery, a great num-
ber of hands, both male and female, are employed at this
establishment; and we understand it has been visited and
much admired by,aiany gentlemen in the trade, as well as
by others who are interested in improvements in cordage.
We cordially wish Messrs. Hucheson and Jarvie every suc-
cess.
