Office of the Commissioners of Patents, with his Petition, on the
6th October 1873.-A communication from abroad by Francis
Cutting, of Woburn, Massachusetts, in the United States of
America.
I, EDWARD OPLE BLAKE, of Leadenhall Street, in the City of London,
Merchant, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN Apparatus for Carbureting and Supplying CarbuRETED ÅIR FOR
LIGHTING AND HEATING PURPOSES," a communication to me from abroad by
Francis Cutting, of Woburn, Massachusetts, in the United States of
America, to be as follows:-
This Invention relates to a peculiar construction and arrangement
of apparatus for carbureting atmospheric air, by the use (by preference)
of the liquid hydrocarbon known in commerce as gasoline (although,
other volatile liquid hydrocarbons may be employed if desired, and
for supplying such carbureted air for lighting and heating purposes.
One of the essential features of this apparatus (which may be either
fixed or portable) is that the carbureting chamber or cylinder is entirely
surrounded by or submerged in water, or in a mixture of water and

obtained.
The gasoline reservoir or carbureting chamber is constructed for this
purpose with an outer jacket, which is kept filled with water, or with
a mixture of water and. glycerine, to avoid thermal and refrigerating
influences.
An automatic atmospheric valve is combined with the gasoline
reservoir or carbureting chamber for the purpose of regulating the
internal pressure, by supplying air to the reservoir or carbureting
chamber when the pressure inside is less than the atmospheric pressure.
This automatic atmospheric valve may consist of a flexible disc, and
a V shaped raised seat, the aperture being covered with wire gauze
having a central boss to which the said flexible disc is secured by a
screw or otherwise. There is also combined therewith a safety valve
constructed as a loaded metallic thimble fitting into an annular mercury
cup, and opening outwards. Also a filler constructed as a canister with
a central pipe entering the filling tube of the reservoir, and depressing
a spring check valve therein situated, such central pipe being provided
, with an exterior annular flange or petticoat fitting into an annular
mercury cup formed on or attached to the outside of said filling tube.
The gasoline pans of the reservoir or carbureting chamber are filled
with sponge or other suitable absorbent material to absorb and present
the gasoline to the passing air, such sponge being confined and preserved
in-its proper position by a superposed network of wire gauze forming the
floor of the air channel.
It is further proposed to arrange and locate the gasoline reservoir
through which the air to be carbureted is to be forced or pumped above
the burners for the purpose of economizing the liquor; but the said'
apparatus may if desired be placed in any other convenient situation.
The air-forcing apparatus may be actuated by a weight and cord, so
that when wound up it will supply air to the carbureting chamber during
any desired length of time..
