An Improved Propelling Apparatus for Aerostatic Vessels.
I, RICHARD CZYGAN, of Hermeskeil, Rhenish Prussia, Germany, Parson 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 propelling apparatus presented by the accompanying drawings brings about
progressive moving towards the direction given by its axis, by virtue of imbibing,
whilst being turned about, the atmospheric air through side-holes in compressing
more and more this air within its center, viz.: close to the axle and in consequence
of the thereafter from one side escaping condensed air producing a reaction, which
gives the required impulsion.
Fig. 1 on the herewith annexed first sheet shows the perpendicular propelling
apparatus elevated, the linear perspective of the same apparatus being offered to
view by Fig. 2; whereas it is horizontally delineated in the Sketch 3, with
horizontal spokes, and in the Sketch 4 with oblique ones; this same horizontal
projection may be seen in the delineation 5 garnished with a flat sheet-metal or
sail-covering D, and in the Sketch 6 the same covering materials being vaulted.
This propelling apparatus is composed as follows:
There is attached to the axle "A" a straight wheel (Fig. 3), or else a declined
one, like that presented by Fig. 4, with its spokes successively lessened more and
more in semicircular progression (see also Fig. 1) that both the semicircles have a
same constructing system as well as any spoke of the one be of symmetrical length
with that diametrically opposite spoke of the other semicircle. The extremities
of the spokes are connected to one another with semicircular metal strips "C,"
annexed to a plain or else curvated sheet or else sail "D," which covers on high all
the wheel. To the tops of the two longest spokes there are attached, either in
perpendicular or in oblique declivity, two bi-angular metal bows "E" (as they may
be seen in the delineations 2-6) bearing two also semicircular metal straps parallel
to the above ones and joined to these with pieces of sheet-metall or cloth F. In
case the wheel attached to the axle of the propelling apparatus is a straight one
(like that delineated in the Sketch 3) some strengthening wires must be guided from
the spokes towards the axle; on the contrary, viz.: as for iuclined wheels the
extremities of the spokes must be connected to one another with wires (as shown
by the Sketch 4).
When the axle "A" duly has been turned, the holes of the metal-bows "E"
will imbibe from every side atmospheric air, which then will be driven towards the
axle, where by continually adduced recent air it will be condensed more and more,
until lastly it is compelled to escape towards the direction given by the axle itself,
thus producing a counter-pressure upon the sheet-metal, or sailcloth-covering "D"
above the wheel and consequently moving on the propelling apparatus towards the
direction of its axle.
As for smaller propellers it will be rather expedient to apply side-faces as well
as the back-curtain made of an only piece, viz. in giving the apparatus that
hemispheric shape, which is shown on the second sheet. On this sheet Fig. 7 shows
the propelling apparatus in front view, Fig. 8 in top view; Fig. 9 represents the
rib twice bent to slings and attached to the axle "a"; Fig. 10 is a cross-section
through the two half hemispheres F and F₁ fastened to the rib c. Fig. 11
represents the propelling apparatus working as wind-motor connected to the
frame P 9 in order to produce a rotatory motion on the cross-axle "a," and Fig. 12
shows the same apparatus where the rib c is distanced from the half hemispheres F
and F, and the motor ceases to work.

In the figures of the second sheet " a represents the axle, in the notch of which
there is pressed by means of the nut "d" (Figs. 9 and 12) the rib c made of a
stout metal strap. Both the extremities are laid together and in the middle of the
strap united by means of rivets. The two slings thus formed by the rib are twice
bent rectangularly. To the inside of the rib there are excentrically fastened two
half hemispheres F and F₁ made of sheet-metal, which are strengthened by the
sheet straps eg g₁h h₁ h,; those of gg, never forming parallel circles, but being
'arranged accordingly to the annexed delineation f.

"till
The same shape of propelling apparatus is well fit for very durable wind-motors
too (Figs. 11 and 12). To this end the boss "b" of the rib "c" is gliding on the
axle "a." The piece
fastly attached to the axle " is pivotly jointed and
by means of the ears and the rods "n to the hemispheres F and F1.
Towards the boss "b" is pressed the weight G by means of the fork-link formed
engaging lever H, that the boss "6" with the rib "
the half hemispheres F and F₁ pressed by the rods n are leaning towards the
rib "c" (Fig. 11) for F and F₁ are connected to the rib c by means of the
pivots "Z." The axle "a" is fastened in the plummer-blocks "p1" which are
connected to one another. To the frame "q" there is connected the reverting
vane S that always turns the apparatus into the direction of the wind. The
plummer-blocks "pq" are connected to the tube R which may turn on a high
stage if the wind alters its direction. From the excentric of the cross-axle "a"
passes through the tube R a wire "w" that is for instance connected to the plunger
of a pump and the like.
If the wind is too violent, the rib c is pressed so very much towards the lever H
that the latter elevates, the two hemispheres open and the wind may pass throughout
the motor, which may also be disengaged by hand by means of a cord passing
through the ear 66
" "shown in Fig. 12. Instead of H and G there may be also
arranged a spring between "p" and "q."
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-
1. The combination, in an improved propelling apparatus for aerostatic vessels,
of a circular disk or covered wheel with a periphery prominent in vertical or else
in oblique direction like the border of a dish and furnished with one slit or with
several ones all opened in the same direction and fit to compel, after duly turning
the apparatus around its axle, from without towards the axle, thus finally forcing the
afore compressed air to escape towards the direction given by the same axle and by
consequence of the herewith produced reaction, to move on the propelling
apparatus towards the opposite direction, substantially as set forth.

2. In a propelling apparatus, that may also be used as wind-motor, the
combination of a twice bent metal strap c" forming two slits E and to which are
excentrically connected two hemispheres F F₁, substantially as set forth.
