London Middlesex, Gentleman, for an invention of IMPROVEMENTS
IN
PROVISIONAL SPECIFICATION left by the said Nathaniel John Holmes at
the Office of the Commissioners of Patents on the 14th March 1882.
NATHANIEL JOHN HOLMES of The Hall, Primrose Hill Road, London, Middlesex
Gentleman, IMPROVEMENTS IN BLEACHING VEGETABLE FIBRES, TEXTILE FABRICS
AND LIQUIDS,
My improvements consist in the employment of an electric current for the
purposes of bleaching by passing the same through the liquid or bleaching
ingredient used to form the bath and thus by means of the electrical decomposition
set up augment the energy of the bath or bleaching agent employed, For this
purpose I make use of an electric current derived from any of the usual known
sources of electrical energy, and by means of suitable electrodes immersed or placed
in circuit with the bleaching agent employed the electric current is caused to
circulate or pass through the bleaching agent and produce electrical decomposition
in amount proportional to the quantity and intensity of the current employed,
thus augmenting the natural action of the bleaching agent and producing a more
rapid and energetic action upon the material substance or liquid under treatment
for bleaching.
I use as the bleaching agent to form the bath in connection with the employment
of the electric current to produce this accelerated action chlorozone known in this
country as Holmes' Ozone Bleach; or the lime liquor prepared from chloride of
Lime but I do not confine my improvement of the application of the decomposition
set up in the bleaching bath by the passage of an electric current to these two
bleaching agents alone, but the decomposition by the electric current may be also
employed with advantage in connection with various other bleaching preparations
to increase their energy and chemical action.

VEGETABLE FIBRES TEXTILE FABRICS AND LIQUIDS
BLEACHING
My improvement consists in the employment of an electric current for the
purposes of bleaching vegetable tissues textile fabrics and liquids by causing an
electric current to pass through the liquid or bleaching solution used to form the
bath in which the material to be bleached is immersed and thus by the action set
up by the electric current develope increased energy and power in the bleaching
action of the agent employed.
For this purpose I make use of an electric current derived from any of the
usual known sources of electrical energy and by means of suitable electrodes
immersed or placed in circuit with the bleaching agent employed or the article to
be bleached the electric current is caused to circulated or pass through the bath and
substance to be bleached and by the chemical or electric action thereby produced
in amount proportional to the quantity and intensity of the electricity employed a
more rapid and energetic action upon the material or liquid under treatment takes
place.
In this application of Electricity for bleaching purposes I do not confine myself
to any particular form or description of bath or bleaching agent which may be the
ordinary Lime liquor bath or "Chlorozone" known in Great Britain as Holmes
Ozone Blench or any other of the usual substances or compounds used for the
purposes of bleaching may be employed in connection with the application of the
Electric current to increase their energy and chemical action.
