Office of the Commissioners of Patents, with his Petition, on the
21st November 1868.-A communication from abroad by Régis
Blanchard, Machinist, of Paris, in the Empire of France.
I, JOHN GARRETT TONGUE, of the Firm of Tongue and Birkbeck,
Patent Agents and Engineers, of 34, Southampton Buildings, Chancery
Lane, in the County of Middlesex, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE TREATMENT AND PREPARATION
OF YARNS OR THREADS FOR WEAVING, SEWING, OR OTHER PURPOSES, AND IN THE
MACHINERY EMPLOYED FOR THIS PURPOSE," to be as follows:-
Certain yarns or threads, such as those made from silk waste, and
spinning waste, and other materials, are rough and hairy, and have knots
or slubs which render their employment difficult for weaving and other
purposes if the surface of the thread is not made smooth and even by
some means, and the object of this Invention relates to certain means
and machinery for effecting this object.
According to this Invention a rubbing of the thread against itself is

page_text: produced by any suitable mechanism, or by causing it to interlace among
or around bars having a to-and-fro or reciprocating movement.
In carrying out this Invention according to one arrangement of
machinery proposed to be employed the yarn or thread to be operated
upon is wound upon bobbins placed at the lower part of the machine;
it then makes a turn around a roller above, and afterwards it also makes
a turn around each one of a series of bars or spindles mounted upon
oscillating arms; and afterwards the yarn or thread passes around other
rollers, and is so conducted as to come in contact with a bar or rod; and
finally the yarn or thread is wound upon bobbins placed at the upper
part of the machine in a suitable state for being woven or employed for
other purposes. 'The yarn or thread is pulled at the upper part, that is
to say, the bobbins upon which the yarn is wound have a rotating
movement imparted to them so as to drag the thread from the first-
mentioned series of bobbins. A break or frictional drags are applied at
intervals upon the axes of the bobbins and rollers to impart a suitable
tension to the yarn or thread during its passage from one series of
bobbins to the other. The bars or spindles around which the yarn is
wound as above described are carried by oscillating arms actuated by
means of cranks or other suitable contrivances so as to impart to them
a reciprocating movement which can be set in motion or arrested at will
by an attendant, the effect of this movement being to cause the yarn or
thread to run round upon the bars or spindles and so produce a rubbing
of the thread upon itself and cause the roughness which is prejudicial
to its employment to be removed. In order that the yarns or threads
may be wound regularly upon the bobbins each of such yarns or threads
passes through a guide or fork, and the base upon which such forks are
mounted has a to-and-fro movement imparted to it. When a thread
happens to break the movement of its bobbin it must be so arranged as
to be arrested without being obliged to stop the whole machine; to
accomplish this the axis of the bobbins is formed in lengths, each of
which length carries only several bobbins and one toothed wheel which
gcars with a wheel mounted upon an axis; and by raising one end of
the spindle upon which the bobbins are placed by means of a lever or
otherwise the wheels will be disengaged and the bobbins cease to turn.
of
As is well understood the machine is composed of a certain number
groups of bobbins combined with the mechanism for setting them

page_text: and the other parts appertaining to them in motion; these groups are
arranged one at the end of each other and can be worked independently.
It will be readily understood that the machinery for carrying this
Invention into practice may be greatly varied without departing from
the nature thereof.
