the Commissioners of Patents, with his Petition, on the 9th
October 1868.
I, SAMUEL TRAGHEIM, of Swinton Street, Gray's Inn Road, in the
County of Middlesex, Interpreter, do hereby declare the nature of the
said Invention for "AN IMPROVED METHOD OF AND APPARATUS FOR WASHING,
DYEING, COOKING, AND WHOLLY OR PARTLY DISSOLVING SUBSTANCES OF VEGETABLE,
ANIMAL, OR MINERAL ORIGIN, AND FOR EVAPORATING AND CONCENTRATING
SOLUTIONS OF THE SAME SUBSTANCES," to be as follows:-
This Invention has for its object to cause a more uniform and rapid
circulation of the water or other fluids with which the substances to be
operated upon are now treated, and this is effected by the use of the
apparatus hereafter described, which is placed in an open boiler or copper
or in a vessel heated by any convenient means. Various forms of
apparatus may be devised of which the following kinds are thosewhich
I prefer :-
A perforated disc supported unon feet or upon a rim. between the

page_text: under part of which disc and the bottom of the interior of the vessel to
be heated are placed fans fitted to a shaft or shafts revolving parallel
with the plane of the perforated disc. The substances and liquids to be
treated are to be placed upon the perforated disc and the rotation of the
fans will assist in keeping up a circulation of water. This I call
apparatus A.
A perforated disc supported upon feet or a rim, some of the per-
forations of which disc shall be protected on the upper side by pro-
jecting pegs or fenders and prevented from being covered down close
by the substances to be washed, dyed, or dissolved; such perforated disc
may be arched upwards or downwards. The substances to be treated
or operated upon are to be placed upon the perforated disc and
the water will rise up and pass through the clothes. This I call
apparatus B.
An upright pipe or cone standing upon legs or on a vandyked or
serrated rim fitted at its upper end with a rim or tubes inclined
sideways or downwards or provided with a fixed cowl with apertures
or with a cowl or system of tubes placed upon a pivot with apertures
sideways, arranged as in the machine called Barker's mill, so that a
liquid passing through them shall cause a horizontal rotatory motion,
and thereby distribute the fluid in all directions upon the substance
under treatment. The substances to be washed, dyed, or dissolved and
the liquids to be evaporated are to be placed around the upright pipe.
This I call apparatus C.
A serpentine pipe the lower end of which shall be near the bottom
of the vessel and its upper end nearly at the level of the highest
point in the vessel. The substances to be operated upon are to be
placed between the upper and lower ends of this serpentine pipe.
This I call apparatus D.
An unperforated disc or disc with vandyked or serrated edges sup-
ported on feet with a fixed vertical pipe rising therefrom, the upper end
of which is provided with tubes or cowls as described for apparatus C.
The substances to be cleansed are to be placed upon the false bottom.
This apparatus I call apparatus E.
If the above mentioned apparatus be placed upon the false bottom
of the open copper or vessel to be heated and the vessel be supplied

place and the washing, dyeing, or other operations will be greatly
facilitated.
