Pierre Lamar at the Office of the Commissioners of Patents, with their
Petition, on the 23rd December 1859.-A communication from abroad
by Daniel Henry Guillaume, of Courbevoie, near Paris, in the French
Empire, Architect.
We, JOSÉ JOAQUIN DE ARRIETA, of Piccadilly, in the County of Middlesex,
Gentleman, and JEAN PIERRE LAMAR, of Bush Lane, in the City of London,
Merchant, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN BLEACHING, CLEANSING, AND DECOLORIZING, AND IN APPARATUS EMPLOYED
THEREIN," communicated to us from abroad by Daniel Henry Guillaume,
of Courbevoie, near Paris, in the French Empire, Architect, to be as
follows:-
According to this Invention, in effecting the bleaching, cleansing and
decolorizing of textile and fibrous materials and fabrics, paraffine, stearine,
and other matters, we cause steam to come in direct, actual, and immediate
contact with the matters under treatment, and thereby to act directly upon the
same. Where desirable, we employ chemical agents, or reagents, or agents
for cleansing, bleaching, and decolorizing of any usual description, and in any
convenient manner, before, during, or after the subjecting of the matters to
the direct action of steam. In the arrangement of apparatus preferred, but
to which we do not restrict ourselves, the vessel or receptacle which contains
the fabrics or matters to be treated, and which is adapted for the reception of

page_text: steam, has water at the bottom, if desirable, to receive impurities resulting
from and to regulate the steam, and may have a moveable cover fitting on,
but not steam-tight at the joint. The steam may be introduced through a
serpentine worm or coil passing up into the receiver through the water at
bottom, or through water spaces around for regulating its temperature, and in
which serpentine worm or coil small hairbreadth slits are cut, as with a watch
manufacturer's saw, in the direction of the circumference, or partly round it, at
intervals just affording openings for slender jets. or streams of steam, which, by
these means, is injected with less disturbance and agitation than if through
Jarge orifices. Or the vessel may be placed over a furnace, and the water
vaporized, or steam otherwise introduced. For affording space for circulation
of the steam about the material to be operated upon, the material may be
heaped up in the vessel, in which a series of uprights, or rods, or bars may bo
arranged in pairs, so that there-may be afforded between those of each pair
space constituting a sort of flue or channel for the steam to circulate about
and within the folds of the material, which bars may be fixtures, or may be
inserted through. orifices in a. falso bottom, and withdrawn after introducing.
the fabric, leaving the required spaces or channels for the steam; or the
matters may be arranged on perforated discs or shelves, or may be wound
upon beams or rollers, revolving or not, and hollow, for the admission of steam
if desirable, stays or separating pieces being placed at intervals between the
layers of material, or may be otherwise arranged as desirable.
