IMPROVEMENTS IN SPINNING TEXTILE AND THREADY FABRICS
Year: 1864

page_text: PROVISIONAL SPECIFICATION left by Count George de Vanssay at
the Office of the Commissioners of Patents, with his Petition, on the
23rd January 1864.
I, COUNT GEORGE DE VANSSAY, of Nonancourt, Departement of the Eure, in
the Empire of France, Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN SPINNING TEXTILE AND THREADY FABRICS,"
to be as follows:-
That which I proposed and have realised is to obtain in a much more
direct manner by a new machine a slub or roving of cotton or other fibrous
O material fit for spinning. The materials before being submitted to the new
machine must pass through machines tending to prepare them for putting on
the cards. In this state they are placed on the new machine behind a card
furnished with an apparatus suitable for making slub or roving, and principally
roving ready to be spun. It is preferable to make special machines for this
purpose, but by additions and modifications in the wool cards, and even the
cotton cards now in use, the special machine in question may be formed. The
Drawing which accompanies this Provisional Specification will give a general
idea of this method of working; in fact it not only shews in what consists
the new machine, but also what is to be added to a wool card to form it into
my new machine as far as modifications of this nature may be applied to an
existing apparatus for a new purpose and work.
The continuous and the dotted red lines on the Drawing indicate the basin
or bowl, the covers or lids, and the pannels in which the new machine is to be

page_text: boxed. The apparatus thus boxed in is an American wool card, but cotton
In this second case I
cards may also be enclosed in the same manner.
entirely suppress the doffer of the cotton cards, and substitute in its place the
apparatus used for making cardings in the spinning of carded wool. This
apparatus is composed of one or more cylinders termed doffers, furnished with
fillet cards, each separated in the direction of the circumference of the cylinder
by spaces not furnished with card teeth. These cylinders receive the cotton
or other fibrous materials which issue in small slivers by means of a detaching
cylinder. The following is the description of the new machine, or rather of
the application of my new method of working to an American carding
engine.
A, endless cloth, on which is placed the product of a first carding gathered
in laps or fleece; B, B', two or three feeding cylinders furnished with fillet
cards intended to deliver these laps little by little; C, large drum of wood,
cast iron, or other material, alternately delivering and taking off the fibrous
material which leaves the feeders B, B¹, to the cylinders I am about to
mention; D, one or several cylinders termed working cylinders, furnished
with card teeth, and one or several small cleaning or stripping cylinders D¹,
the functions of which consist in returning to the large drum the fibrous
material taken by the workers. These cylinders are placed on the upper part
of the drum; E, cylinder, termed fly, furnished with fillet cards, serving to
arrange all the threads or filaments parallelly on the drum, so that they may
be easily taken by the cylinders, of which mention will now be made. F. one
or several cylinders termed doffers, furnished with fillet cards, each separated
in the direction of the circumference of this cylinder by spaces not furnished
with card teeth. These cylinders receive the cotton or the other fibrous
materials, which leave in small slivers by means of a detaching cylinder or
licker in G; H, H', pressing arrangement of any description, either rotary
rubbing apparatus or other, intended to form from these slivers of small size
a real roving ready to be wound; I, I, one or more beams applied in front
of the apparatus, and serving to support bobbins on which wind together or
separately all the slubs or rovings issuing from the pressing apparatus. These
rovings might equally be allowed to fall into any sort of receiver, such as
cans, boxes, or other. This apparatus should be boxed or enclosed in three
distinct parts, which during the working of the machine may be used together
or separately, first, in the space comprised between the cylinder F and
the feeders B, B', from the point X to the point X and to the point X",
is placed a species of basin, which perfectly encloses the drum, to which it
may be brought more or less near. This basin or reservoir may be composed

page_text: of an iron plate, a wooden arch, a grating of any sort, or partly of sheet iron
and partly of grating. The basin is supported at each side on, secondly, two
fixed pannels (indicated by the continuous red line) placed more or less near
the drum, and on which rests, thirdly, a movable or fixed hood or cap (indi-
cated by the dotted red line) composed of one or more pieces. This cap is
composed of two sides resting on the fixed sides above described, and united
together by a sheet iron plate or a wooden cover of the entire breadth of the
card, and which shuts in all the upper part comprised between the feeders B
and the cylinder E. These three parts may be used together or separately,
that is to say, the basin or the cover or the pannels only may be used, or two
of the three at once. In this case the shape of the three parts is modified as
may be required.
