Ventilating and like Purposes.
I, HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street Strand W.C. London in the County of Middlesex Civil
Engineer do hereby declare the nature of this invention a communication to me from
abroad by Heinrich Klein of Mülheim /Rh. in the Empire of Germany Manufacturer
to be as follows:-
This invention consists in an improved ventilator or blower for the moving of air,
gases, smoke and the like. In a suitable shaft, chamber or the like is led a pipe
terminating in a flaring conical mouth directed towards that direction in which the air
or the like is to be moved. The said flaring mouth is bridged near the base by a
suitable support carrying in the centre, axially directed in the conical mouth, a screw
threaded pin, and on said pin is screwed a disc, of preferably slightly smaller diameter
than that of the open end of the conical mouth. By screwing down said disc more or
less, the orifice of this tube is transformed into a ring of greater or less thickness
Steam, air, water or other suitable material is forced with pressure through said orifice
and passes therefrom in a diverging conical current or spray causing air gas smoke or
the like to be drawn along the shaft or chamber.

I HERBERT JOHN HADDAN of the firm of Herbert & Co., Patent Agents of
18 Buckingham Street Strand W.C. London in the County of Middlesex, Civil
Engineer do hereby declare the nature of this invention, a communication to me from
abroad by Heinrich Klein of Mülheim "/Rh. in the Empire of Germany, Manufacturer,
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention consists in an improved ventilator or blower for the moving of air,
gases, or smoke and the like. In a suitable shaft, chamber or the like is led a pipe
terminating in a flaring conical mouth directed towards that direction in which the
air etc. is to be moved.
The said flaring mouth is bridged near the base by a suitable support carrying in
the centre, axially directed in the conical mouth, a screw threaded pin and on said pin
is screwed a disc of preferably slightly smaller diameter than that of the open end of
the conical mouth. By screwing down said disc more or less the orifice of this tube
is transforined into a ring or annular space of greater or less breadth. Steam, air
water or other suitable fluid is forced with pressure through said orifice and passes
therefrom in a diverging.conical current or spray causing air, gas, smoke or the like
to be drawn along the shaft or chamber.
Reference being made to the accompanying drawings, A B is the shaft, C the
conical flaring mouth to the pipe J, D is the bridge E being passages on each side
thereof, G is the annular disc secured upon a spindle in the axis of the mouth.
Fand H are nuts for. adjusting the position of the disc G.

Having now particularly described and ascertained the nature of my said inven-
tion and in what inanner the same is to be performed I declare that what I
claim is.
The combination with a shaft or the like A B of a flaring mouth C, pipe J
communicating therewith and disc G adjustably placed in the mouth C substantially
