PROVISIONAL SPECIFICATION.
An Improved Method of and Means for Increasing the Efficiency of
Steam Generators.
I, GUILLERMO ANTONIO FARINI, of Dartmouth Lodge Perry Vale, Forest
Hill in the County of Surrey, Gentleman do hereby declare the nature of this
invention to be as follows:-
My invention relates to an improved method of and means for increasing the
mechanical work done by a steam generator in a given time, and by the com-
bustion of a given quantity of fuel, thereby increasing the efficiency of said
generator.
In carrying my said invention into effect, I cause atmospheric air to be injected
into the steam or water space, or both, of the generator by means of a pump or
pumps attached to and operated by the prime motor or motors driven by the
generator or by a separately operated pump or pumps, or I may employ any form
of injector, inspirator or the like for effecting said purpose.
I preferably, in order to obtain the best economical result, heat the air before or
during injection, deriving said heat from the waste products of combustion, or from
the radiation from any part or parts of the generator.
I may also inject water, vapor, or steam in combination with the air aforesaid,
as a feeding arrangement and may use a double acting pump or any form of
injector or the like for this purpose.
I find in actual practice, that the result of such injection affords a greatly
increased effect, and that the power or energy absorbed in operating the pump,
injector or equivalent is negligible relatively thereto.

COMPLETE SPECIFICATION.
An Improved Method of and Means for Increasing the Efficiency of
Steam Generators.
I, GUILLERMO ANTONIO FARINI, of Dartmouth Lodge, Perry Vale, Forest
Hill, in the County of Surrey, Gentleman, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates to an improved method of and means for increasing the
mechanical work done by a steam generator in a given time and by the com-
bustion of a given quantity of fuel thereby increasing the efficiency of said
generators.
In order to clearly illustrate my said invention, I have appended the accom-
panying sheet of drawings in which the arrangement of the pump is shewn partly
in section.
In carrying my said invention into effect, I cause atmospheric air to be ejected
into the steam or water space or both of the generator.
I preferably, however, use a trunk piston pump, conveniently attached to any
part of the motor or engine so that it may be driven by it. Referring to the
drawing, A is the inlet valve for the air supply, controlled by a spiral spring a.
The piston B is provided with a foot valve D opening to ports C so that the first
compression may take place in the lower cylinder or chamber above B on the
Prima77

upstroke thereof; B being operated by the hollow trunk G. On said upstroke
the valve D is closed and E is opened, controlled by the stop F.
A fixed piston
or plunger H is arranged so as to effect a further compression and is provided
with suitable channels or ports to inject the mixture of air or air and steam, or
air and water into the generator through the upper part thereof. The trunk G
is operated by a crank, eccentric sheave or other equivalent means by the
crosshead I.
I preferably, in order to obtain the most economical result, heat the air before
or during injection, deriving said heat from the waste products of combustion, or
from the radiation from any part or parts of the generator, by passing it through
a coil, pipe or sheaf of pipes suitably placed to absorb said waste heat.
I also prefer to inject water vapor or steam in combination with the air aforesaid
as a feeding arrangement, and may use a double-acting pump, or any form of
injector for that purpose, always, however, employing the type of pump hereinbefore
described.
I find in actual practice that the result of such injection affords a greatly increased
effect, and that the power or energy absorbed in operating the pump or its equivalent
is negligible relatively to such effect.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
First. The method of and means for injecting air into a steam generator
substantially as herein described with reference to the drawings and for the purpose
specified.
Second. The method of and means for injecting heated air and water or vapor
into a steam generator substantially as herein described, and for the purposes
specified.
