Henry George Hacker, at the Office of the Commissioners of Patents,
with their Petition, on the 14th April 1860.
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:-
Our Invention consists in arrangements of machinery hereafter described,
whereby silk or other threads of which the chenille is to be formed, are laid
round two main or foundation wires, have other small wires or threads applied
thereto, according to whether soft or stiff chenille is to be produced, are then
cut, and are held between the small wires or threads, which are twisted, and
thus the chenille is formed.
Our Invention also consists in the construction of a gathering reel, which
twists or assists in twisting the small wires or threads, takes up the chenille
as it is finished, and exposes a fresh surface for winding it, in order to avoid
the crushing of the chenille by winding layer upon layer.
The carriage carrying all the apparatuses except the foundation wires may
be made to move along a table provided for the purpose, or it may be
stationary, and the foundation wires may be moved. The whole of the motions
are derived from one crank handle.
We proceed to describe the machinery, supposing the foundation wires to
be stationary, and the carriage to move along the table:-A screw is fixed

page_text: along the whole length of the table, and at the side thereof a nut on the base
of the carriage fits over the screw, and by turning the screw the carriage is
made to travel; the rotary motions to the bobbins carrying the silk or other
threads and also to the twisting apparatuses, are derived by pulleys and bands,
which take their motion from the revolution of the screw. The bobbins
carrying the silk or other threads revolve round and cover the foundation wires
which pass through guides in standards on the carriage bed; a small wire or
thread is laid next the foundation wires before the silk threads are wrapped
on, and after they are wrapped a second small wire or thread is laid on the
top of the silk threads; by the onward motion of the carriage the chenille
threads come in contact with a knife, which is so placed as to present itself
under and between the foundation wires, and thus the chenille threads are cut;
they leave the foundation wires, which are carried clear of the twisting appa-
ratuses, and are held between the two small wires or threads to be twisted, as
next explained.
For twisting we employ sometimes one and sometimes two apparatuses.
The first consists of a frame made to revolve vertically, and carrying two
wheels furnished with wires at their circumference held between two discs ;
the wires in the two wheels are so set that during the revolution of the wheels
the wires in one wheel enter the spaces between the wires in the other wheel,
thus a slight nipping action takes place not injurious to the chenille, but
sufficient to hold it while the twist is being given by the rotation of the appa-
ratus; the chenille then passes on to the gathering and twisting reel, which
rotates vertically, and by means of toothed gear, worm, and worm wheel, and a
central screw spindle, is made at the same time to revolve round and constantly
to shift its position upon the screw spindle.
