IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF CHENILLE
Year: 1859

page_text: LETTERS PATENT to Charles Edmund Wilson, Manufacturer, and Henry
George Hacker, Warehouseman, both of Monkwell Street, in the City of
London, for the Invention of "IMPROVEMENTS IN MACHINERY FOR THE
MANUFACTURE OF CHENILLE."
PROVISIONAL SPECIFICATION left by the said Charles Edmund Wilson
and Henry George Hacker at the Office of the Commissioners of
Patents, with their Petition, on the 26th October 1859.
We, CHARLES EDMUND WILSON, Manufacturer, and HENRY GEORGE HACKER,
Warehouseman, both of Monkwell Street, in the City of London, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
THE MANUFACTURE OF CHENILLE," to be as follows:-
We first erect a table or platform, and place rails thereon or grooves therein
for the reception of the wheels of a travelling carriage, hereafter described.
Over the table we stretch a wire with a groove at top and bottom, this wire
passes from end to end of the table, and through guides and spindles on the
carriage. The front. of the carriage carries at top a bobbin containing a fine
wire, which is guided by a guide pulley into the upper groove in the wire, the
grooved wire with its fine wire passes through a guide, then through a hollow
spindle carrying a bobbin containing silk or other material of which the
chenille is to be formed. The silk from the bobbins is passed through flyers
on the hollow spindle. Rotation being imparted to the flyers, causes them to

page_text: wrap the silk round the two wires, and the carriage being caused to advance
by means of a weight or other suitable contrivance, brings the two clothed
wires between two guide rollers in the back frame of the carriage, when a
third wire, fine, like that secondly herein-before mentioned, is laid upon the
silk; the advance of the carriage brings the silk in contact with a knife, which
enters the bottom groove in the grooved wire. The two fine wires are twisted,
whereupon the silk cut as chenille is carried away upon them. For the fine
wires threads may be substituted, and instead of the carriage being caused to
travel, it may be stationary, and the wires may be drawn through it.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Edmund Wilson and Henry George Hacker, in the
Great Seal Patent Office on the 26th April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
EDMUND WILSON, Manufacturer, and HENRY GEORGE HACKER, Warehouseman,
both of Monkwell Street, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria; by Her Letters
Patent, bearing date the Twenty-sixth day of October, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the said
Charles Edmund Wilson and Henry George Hacker, Her special licence that
we, the said Charles Edmund Wilson and Henry George Hacker, our execu-
tors, administrators, and assigns, or such others as we, the said Charles
Edmund Wilson and Henry George Hacker, 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 THE MANUFACTURE OF
CHENILLE," upon the condition (amongst others) that we, the said Charles
Edmund Wilson and Henry George Hacker, or one of us; our executors
or administrators, by an instrument in writing under our or their, or one
of our or their hands and seals, should particularly 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 immediately after the date of
the said Letters Patent.

page_text: NOW KNOW YE, that we, the said Charles Edmund Wilson and Henry
George Hacker, 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 thereof, reference being had to
the Drawings hereunto annexed, that is to say:-
Since the filing of our Provisional Specification, we have discovered that our
machinery is not capable of producing perfect chenille when a grooved wire is
employed for receiving the wrapping of silk or other thread. We, therefore,
abandon the grooved wire, and proceed to describe the machinery adapted to
wrap the silk or other thread round two wires, and to the cutting of the
thread between the two wires.
We erect a table or platform, in which dovetailed grooves are formed to
correspond with grooves formed on a travelling carriage, to be hereafter
described; or we place rails on or form grooves in the table or platform for
the reception of the wheels of the said travelling carriage. Over the table we
stretch two wires side by side, which extend from end to end of the table, and
pass through guides and spindles in the carriage. The front of the carriage
carries at top a bobbin containing a fine wire, which is guided by a guide
pulley over and between the two wires; these wires with the fine wire pass
through a guide borne by the carriage, then through a hollow spindle also on
the carriage carrying a bobbin, containing silk or other material of which the
chenille is to be formed. The silk from the bobbin is passed through flyers on
the hollow spindle. Rotation being imparted to the flyers, causes them to
wrap the silk round the wires, and the carriage being caused to advance by
means of a weight or endless screw, or other suitable contrivance, brings the
clothed wires against a guide roller, or between two guide rollers in the back
frame of the carriage, when a fine wire, like that secondly herein-before
mentioned is laid upon the silk, the advance of the carriage brings the silk in
contact with a knife, which enters under and between the two main wires.
The two fine wires are twisted, whereupon the silk cut as chenille is carried
away upon them. For the fine wire, threads may be substituted, and instead
of the carriage being caused to travel it may be stationary, and the wires may
be drawn through it.
Figure 1 of the accompanying Drawings is a side elevation; Figure 2 is a
plan; and Figure 3, a view of one end of a machine for the manufacture of
chenille constructed according to our Invention. A, A, is a frame or platform
supported on standards B, B. This frame carries a carriage C, along which
frame it is free to travel in dovetailed grooves a, a, as will be hereafter
described; D, D, are brackets one on each end of the machine, and between

page_text: which the two main wires E, E, are stretched; F is a screwed shaft extending
from end to end of the machine, and passing through a nut on the lower part
of the travelling carriage. Rotary motion is imparted to this shaft F by a
winch handle G; H is a grooved wheel keyed to the opposite end of the
shaft F to that which carries the winch handle G; I' is another grooved wheel
on a shaft, which carries another grooved pulley I of or about the same size as
the wheel H; J is a strap imparting motion from the wheel H, to the wheel I'
and pulley I; K is a strap passing round the pulley I, and another smaller
grooved wheel L mounted on a spindle M, to which the fine wires b, b₁ used
in the manufacture of the chenille are fastened. On motion being imparted
to the winch handle G, rapid rotary motion is conveyed to the spindle M, and
consequently to the fine wires b, b¹. The screwed shaft F in its course through
the travelling carriage, passes through the centre of a bevil wheel N, which
is secured to the shaft F by a pin which fits into a slot formed lengthwise in
the said shaft F, so that when the shaft F revolves, the bevil wheel N rotates
with it. This wheel N is in gear with a wheel mounted on a shaft P,
which also carries another wheel Q in gear with a wheel R, which is mounted
on a shaft carrying a grooved pulley S, round which a strap passes to a small
pulley T; V is a disc of metal attached to the pulley T, carrying a flyer and
bobbin W filled with silk or other material used for the manufacture of the
chenille. The same power (viz. that applied through the winch handle G),
which communicates rotary motion to the fine wires b, 6¹, also causes the
bobbin W through the gearing just described to revolve, and at the same time
drives the travelling carriage along the screwed shaft F. The pulley T is
mounted on a hollow spindle, which is supported by a bracket X fixed to the
travelling carriage. The main wires E, E, pass through this hollow spindle,
and through holes formed in two brackets Y fixed to a bar Z. Fine wire
which is attached at one end as before described to the spindle M, is led from
a bobbin c through the bracket Y, under and between the two main wires E, E.
Silk or other material from the bobbin W passes through a small eye fixed
to the disc, and is wound round the wires E, E, and fine wire b, the whole,
that is, the wires E, E, the fine wire b, and the silk are surrounded and passed
over by the hollow spindle which is moving with the parts attached thereto
in a horizontal direction. Soon after the hollow spindle has left the covered
wire; the second fine wire b' also attached to the spindle M, and led from a
bobbin c', through a guide d over a roller, and beneath a roller enters between
and over the two main wires E, E, a knife which passes through a support,
and is held therein by a thumbscrew, enters under and between the main
wires E, E, and cuts the silk, whilst the two fine wires b; and 6', holding the

page_text: cut silk between them become twisted, and thus the chenille is formed. A
screw k passing through a guide regulates the position of the knife. One
motion imparted to the screwed shaft, sets the whole of the parts of the
machine in simultaneous action.
And having now described the nature of our said Invention and in what
manner the same is to be performed, we declare that we make no claim to
any of the parts of the machinery herein-before described taken separately, nor
do we make any claim to the employment of the foundation composed of two
wires, as the employment of such double wire foundation forms part of the
subject of an Invention for which we obtained Provisional Protection the
Fourteenth day of April instant; but we claim, the combination of machinery
for the manufacture of chenille, consisting of a travelling carriage carrying
silk or other thread wrapping apparatus, a cutting blade, and fine wires, and
of an apparatus for twisting the same, all constructed and acting substantially
in manner herein-before described.
In witness whereof, I, the said Charles Edmund Wilson, have hereunto
set my hand and seal, this Twenty-sixth day of April, One thousand
eight hundred and sixty.
CHARLES EDMUND WILSON
