PROVISIONAL SPECIFICATION.
Improvement in Air Propellers Worked by Water.
CHARLES VOGEL, Electrician, 68, Grafton Street, Fitzroy Square, London, W.,
do hereby declare the nature of this invention to be as follows:-
-
I provide in a suitable aperture in a wall of a room an ordinary vertical
centrifugal fan with straight sheaves set at an angle of 45° & round its periphery
I fix a waved or otherwise suitably shaped strip of metal enclosed in a suitable
casing. On the right & left hand top side I provide two jet inlets & at the bottom
a suitable outlet for the waste water. The pressure of the inflowing water acting
on the waved strip of metal, will rotate the fan or air propeller either to the
left or right according from wich side the water is allowed to enter, thus in
the one instance extracting the foul air from the room & in the other instance
injecting fresh air into the room. If required I provide also a hinged lid or
cover to close the fan or air propeller when not in use to prevent draught.
Dated this 6th day of April 1899.
Popov air propellers worked by water.
I, CHARLES VOGEL, of 68, Grafton Street, Fitzroy Square, London, Engineer,
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:-
The object of this invention is to provide a simple and effective air propeller
worked by water that is readily reversible in its operation and serves either to
extract foul air or to inject fresh air as required.
This I effect by the improved mechanism hereinafter described.
In the ac-
companying drawings wherein similar letters of reference indicate corresponding
parts, Figure 1 is a transverse, and Figure 2 a longitudinal section of an air
propeller constructed according to my invention. a is an air fan mounted on
a spindle b, and furnished with a ring c of a channel section, and a corrugated
metal band d, or its equivalent. Such ring and band together form a rim and
serve to convert the air propeller into a combination air propeller and water
wheel which is reversible in its operation as presently described. This rim is
enclosed within a casing e that forms a chamber wherein it rotates, and whereto
water is conveyed from any convenient source by means of supply pipes f, that
are coupled to nozzles g fitted in the casing e and furnished with cocks, (not

shewn in the drawings), whereby the water supply is regulated. An outlet
pipe is fitted to the casing to carry off the waste water, while a narrow central
opening el extends round the inner circumference of such casing to allow the
rim of the combined air propeller and water wheel to rotate freely. The
spindle runs in adjustable cone bearings ', held in position by lock nuts 1,
so that when such bearings become slack they can be readily re-adjusted.
a cover hinged to the apparatus in any convenient manner, in order to close the
air way when desired. I fit such apparatus in the wall or elsewhere in any con-
venient position, and connect the same with the water supply pipes. When
so fitted the cock on one of such pipes opened thus causing the water to flow
into the casing e and impinge upon the rim of the combined air propeller and
water wheel thus driving. it in the required direction to extract foul air or inject
fresh air as desired, while to reverse its operation it is only necessary to shut
off one cock and turn on the other when an inflow of water in the opposite
direction is induced thus driving the air propeller in that direction. I would
here observe that I do not confine myself to the precise details of construction
herein before described as the same admit of variation without departing from
the essential features of my invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is
The improved reversible air propeller worked by water, constructed, arranged
and operating, all substantially as hereinbefore described and shewn.
