PROVISIONAL SPECIFICATION.
An Improved Method of Applying Dye and other Liquids to
Feathers.
I, HENRI NICOLAS BOUR, of 29, Rue des Petites Ecuries, Paris, France,
Dealer in Feathers, do hereby declare the nature of this invention to be as
follows:-
Hitherto feathers have been dyed by dipping in a dye-bath of suitable
composition according to the colour to be produced. This method is, however,
slow and expensive and it is hardly possible to dye a feather more than two
colours.
My invention consists in a new process of dyeing feathers, which is not only
free from the above objections but enables the feathers to be dyed even after
being curled, a result never heretofore attained. This new process consists in
applying the dye or other liquid to the feather in an atomized condition by the
employment of an ordinary atomizer or spray producer.
The dye or other liquid to be applied on the feather, is discharged in the form
of fine spray on to the feather at such points and for such a length of time as to-
produce the desired effect. The mist formed by the atomized dye liquid when
sprayed upon the feather will dye it without moistening it so that, if it has already
been curled in the ordinary way, the curl will not thereby be taken out of it. By
thus applying dyes of different colours, highly varied and entirely novel effects.
may be produced.
My process is applicable not only for dyeing feathers but also for producing othe
effects, such for example as bleaching, mordanting, and the like, and the invention
extends to applying all such liquids as bleaching agents mordants, varnishes, etc.,
to feathers by atomizing or spraying. I may employ any kind of atomizer,.
whether operated by ball, pump, or bellows, which being well known need no
further description.

An Improved Method of Applying Dye and other Liquids to
Feathers.
I, HENRI NICOLAS BOUR of 29, Rue des Petites Ecuries, Paris France,
Dealer in Feathers, do hereby declare the nature of this invention and in what-
manner the same is to be performed to be particularly described and ascertaine.l
in and by the following statement :-
Hitherto feathers have been dyed by dipping in a dye-bath. This method is
however slow and expensive and the production of variegated or parti-coloured
shades upon the same feather is hardly possible by this method which at most-
admits of dyeing, a feather two different colours.

take the curl out of it if it has already been curled in the ordinary way, this
method of dyeing feathers after curling enabling a result to be obtained which has
not heretofore been possible. Moreover by thus applying dyes of different colours,
highly varied and entirely novel effects may be produced.
My process is applicable not only for dyeing feathers but also for producing
other effects, such for example as mordanting, bleaching, varnishing, and the like,
and the invention extends to applying all such liquids as mordants, bleaching
agents, varnishes, etc. to feathers by atomizing or spraying. I may employ any
suitable kind of atomizer whether operated by elastic, ball, pump, bellows, or by
the breath, which being well known need no further description.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The herein described process of applying dyeing, bleaching, or other liquid
to feathers which consists in spraying the dye or liquid in a finely-atomized
condition upon the feather by means of a liquid atomizer as and for the purpose
specified.
2. The herein described process of dyeing feathers parti-coloured, which consists
in spraying the dye in a finely-atomized condition upon different parts of the
feather as specified.
3. The herein described process of dyeing feathers which consists in first curling
the feathers in the ordinary way and then applying the dye or dyes by spraying
the same in a finely-atomized condition upon the feather as described.
4. As a new article of manufacture, a feather which has first been curled and
then dyed by having the dye sprayed upon it in the form of a mist produced by a
liquid atomizer or pulverizer as specified.
