Year: 1870

page_text: LETTERS PATENT to Marmaduke Wilkin, of 2, Saint James' Terrace,
Parish of Paddington, County of Middlesex, Gentleman, John
Clark, of 8, Belmont Terrace, Parish of Kensington, County of
Middlesex, Engineer, and Adam Scott, of 3, Blomfield Crescent,
Parish of Paddington, County of Middlesex, Gentleman, for the
Invention of "IMPROVEMENTS IN SUBDIVIDING PARTICLES OF WATER AND
PROVISIONAL SPECIFICATION left by the said Marmaduke Wilkin,
John Clark, and Adam Scott at the Office of the Commissioners
of Patents, with their Petition, on the 1st March 1870.
We, MARMADUKE WILKIN, of 2, Saint James' Terrace, Parish of
Paddington, County of Middlesex, Gentleman, JOHN CLARK, of 8,
Belmont Terrace, Parish of Kensington, County of Middlesex, Engineer,
and ADAM SCOTT, of 3, Blomfield Crescent, Parish of Paddington,
County of Middlesex, Gentleman, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN SUBDIVIDING PARTICLES OF WATER

page_text: AND OTHER FLUIDS, AND APPLYING THE SAME TO SANITARY AND OTHER PURPOSES,"
to be as follows:-
This Invention has for its object the subdividing particles of water
or other liquids so as to form a fine spray or mist, and the following
applications of the Invention are given as some of the uses to which it
may be applied.
1st. For reducing the temperature and rendering the air more healthful
in halls, theatres, and other similar places where crowds assemble,
also in dwelling houses or similar places in hot sultry weather, also in
hot countries.
2nd. For reducing the temperature of engine and furnace rooms in
_steam_ships,_also in ships' holds,-cabins,-and-other-places-of-a-similar-
kind.
3rd. For purifying the air in sick rooms, or in fever wards in hospitals
or similar places.
4th. For purposes of distillation by discharging the "wash” to be
distilled into a stratum of hot air or other medium, thereby bringing
the wash more effectually into the vaporising process without subjecting
it to the boiling process.
The means whereby we attain these objects are as follows:-We fit
up a vessel to contain the liquid and make small perforations in the
bottom to permit the liquid to escape. We cover the said perforations
with a piece of cloth to distribute the liquid equally by moistening the
cloth. We fit underneath one or more revolving circular brushes made
with bristles or other materials in the usual way. The brushes are so
near the cloth as to touch it. When the brushes are made to revolve
the liquid is distributed in fine spray by being projected from the
bristles of the brushes. We also add wires or bars within reach of
the bristles and fitted transversely to the direction of the rotation, so that
the bristles shall strike the said wires or bars and throw off the liquid
with which they have been charged from the cloth. The said vessel
may also be furnished with a conductor or pipe having the said per-
forations in it and covered with cloth as aforesaid. The revolving
brushes may be driven by a strap in connection with engine power or
may be operated by hand. We also use under certain circumstances
flat brushes having a reciprocating movement imparted to them instead
of the revolving circular brushes described. In the domestic applica-
tion of the Invention the brushes may be combined with a fan or

page_text: fans, which may either be attached to the spindle on which the brushes
revolve or be otherwise applied in connection with it. This Inven-
tion may also be applied in the manufacture of shot by charging the air
contained in the towers or other places with moisture by the said
apparatus of brushes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Marmaduke Wilkin, John Clark, and Adam Scott,
in the Great Seal Patent Office on the 1st September 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MARMA-
DUKE WILKIN, of 2, Saint James' Terrace, Parish of Paddington,
County of Middlesex, Gentleman, JOHN CLARK, of S, Belmont Terrace,
Parish of Kensington, County of Middlesex, Engineer, and ADAM
SCOTT, of 3, Blomfield Crescent, Parish of Paddington, County of
Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of March, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Marmaduke Wilkin, John Clark, and Adam
Scott, Her special licence that we, the said Marmaduke Wilkin, John
Clark, and Adam Scott, our executors, administrators, and assigns, or
such others as we, the said Marmaduke Wilkin, John Clark, and
Adam Scott, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN SUBDIVIDING PARTICLES OF WATER AND
OTHER FLUIDS, AND APPLYING THE SAME TO SANITARY AND OTHER PURPOSES,'
upon the condition (amongst others) that we; the said Marmaduke
Wilkin, John Clark, and Adam Scott, our executors or administrators,
by an instrument in writing under our, or their, or one of their
hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Scal Patent Office

page_text: within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said Marmaduke Wilkin, John Clark,
and Adam Scott, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement.
This Invention has for its object the subdividing particles of water or
other liquids, so as to form a fine spray or mist, and the following
applications of the Invention are given as some of the uses to which it
may be applied :-
1st. For reducing the temperature and rendering the air more healthful
in halls, theatres, and other similar places where crowds assemble, also
in dwelling houses or similar places in hot sultry weather, also in hot
countries.
2nd. For reducing the temperature of engine and furnace rooms in
steam ships, also in ships' holds, cabins, and other places of a similar
kind.
3rd. For purifying the air in sick rooms, or in fever wards in hospitals
or similar places by distributing disinfectants therein.
4th. For purposes of distillation by discharging the "wash" to be
distilled into a stratum of hot air or other medium, thereby bringing the
"wash more effectually into the vaporizing process without subjecting
it to the boiling process.
"
5th. For manufacture of shot by charging the air contained in the
towers or other places with moisture.
The means whereby we attain these objects are as follows:-We fit
up a vessel to contain the liquid and make small perforations in the
bottom to permit the liquid to escape. We cover the said perforations
with a piece of cloth or sponge to distribute the liquid equally. We fit
underneath one or more revolving circular brushes made with bristles or
other materials in the usual way. The brushes are so near the cloth or
sponge as to touch them. When the brushes are made to revolve the
liquid is distributed in fine spray by being projected from the bristles of
the brushes. We also fit wires or bars within reach of the bristles, the
said wires or bars being transverse to the direction of the rotation of
the brushes so that the bristles shall strike the said wires or bars and
throw off the liquid with which they have been charged from the clothi

page_text: Figures 1 and 2 are elevations at right angles of the general arrange-
ment of the brush and liquid vessel. It is raised on the top of a pole
which is fitted to a stand. The stand may be fitted with wheels to make
it more portable.
"A" is the vessel filled with liquid. There are one or more perfora-
tions in the bottom covered by the cloth "B." The circular brush "C"
is carried in bearings "D," D," and driven by the line "E." "F, F," are
wires or bars placed transversely to the brush.
Figure 3 is an elevation of the arrangement for cooling the air or
effecting the other objects named in this Specification, or other purposes
where the operation of cooling or damping is required on a larger scale.
It consists of a central spindle "A" having a series of circular brushes
fitted on it and driven by a strap from the engine or other motive power
by the pullies "B, B." The supply pipe "C" is perforated and covered
with cloth to diffuse the liquid equally. The supply of water or other
liquid is contained in a tank, or, at sea, may be led in from the outside
of the ship. "D, D," are wires or bars secured in the end plates "E, E."
The holes in these plates are slotted to permit of the adjustment of the
bars as the tips of the brushes get worn. "F, F," are supporting
brackets fixed to the under side of the deck when fitted on board ship.

page_text: Figure 4 is an arrangement by which the operation of the brush can
be combined with a fan or punka. The liquid is contained in the
vessel "A," and is supplied to the brush by the duct or wick "B" by
capillary attraction.
Having now described the nature of our said Invention, and by what
means we carry the same into practical effect, we would have it clearly
understood that we do not confine ourselves to the precise details herein
set forth and illustrated on the annexed Sheet of Drawing, as modifi-
cations may be made in the shape, arrangement, and combination of
various parts of our Invention while retaining its fundamental
characteristics.
-In-witness-whereof,-wc,-the-said-Marmaduke-Wilkin,
John Clark,
and Adam Scott, have hereunto set our hands and seals, this First
day of September, in the year of our Lord One thousand eight
hundred and seventy.
