I, HENRI CHARVET, of Lille, in the Department of the Nord, in the Empire
of France; Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE SPINNING OF COTTON, AND IN ITS VARIOUS APPLI-
CATIONS," to be as follows:-
After I have passed the raw cotton or cotton wool through the beater or
scutcher I dye it of various colours, according to the effect or design I intend
to produce; I then repass it by the opener and the lap scutcher, on leaving
which, I submit it to the carding machine, then to the combing machine, and
then to the slubbing or bobbin frame. The mode of preparation will vary
according to the lighter or deeper mixture, or more or less apparent design to
be produced. If a very slightly marked or undecided mixture be desired, I
take slubs or rovings of as many colors as necessary, but I take care that the
slubs of the colours which are most striking are slightly the thinnest. If, how-
ever, it is imperative that only slubs or rovings of equal thickness be used, I
take more slubs of the lighter shades of colour than those of deeper shade. If
I require a decided mixture, I have recourse to a contrary arrangement, that
is to say, I take more slubs of the showy colours and fewer of the less striking.
In the one or other case the number of slubs varies with the effect or design
to be produced. From the slubbing frame I carry the slubs or rovings to the
stretcher or billy, putting two threads of this mixture together. If it is desired

page_text: to deepen the mixture, I put one mixed thread and one of an even colour.
The same effect is obtained by putting two mixed threads together. From
the stretcher I pass to the spinning jenny. To obtain the mixture in question
I here put two slubs or rovings of one mixture, and when I desire to deepen
or lessen the mixture I put a mixed roving with another of uniform colour,
according to the effect required. On leaving the spinning jenny I double and
twist two threads of the same mixture together in the doubling and twisting
machine. I generally use only the longest stapled and most brilliant cotton
that can be obtained, my object being principally the manufacture of rich and
somewhat high-priced goods. For the mixtures which are to be slightly
marked, simple or single colour may be preserved as far as the slubbing frame,
and the mixture be commenced only at the stretcher or billy, or even at the
spinning jenny, by putting, for example, one coloured slub or roving and one
white one together, or other colours. From the result of this last operation
I take two mixed spools, which I pass together to the spinning jenny; I also
make mixed threads in simple warp. I begin my mixture at the slubbing frame,
and end it at the spinning jenny, as above indicated; or the mixture may be
commenced at the carding machine. In this case, I take the desired colours
in the requisite proportions, and the cotton then passes through all the pro-
cesses of spinning. The employment of these threads does not exact any
particular care, whether used for sewing, for weaving, for knitting, or for
chenille. Their use whether for even or striped woven fabrics, chenille, glove-
making, lace, or other purpose, will ensure the production of the most novel
and tasteful effects. These combinations are not only applicable to cotton, but
to silk, flax, and wool, whether these materials be used alone or mixed.
