SUBMERGED FEATHERING IPADDLE-WHEEL.
Specification of Letters Patent.
Patented March 2, 1909.
Application filed February 8, 1906. Serial No. 300,127.
To all whom it may concern:
Be it known that I, LADISLAV V oJZiCEK, a subject of the Emperor of Austria-Hungary, residing in Prague, Kingdom of Bohemia, in the Austro Hungarian Empire, have invented new and useful Submerged Feathering Paddle-Wheels, of which the following is a specification.
My invention relates to improvements in submerged feathering paddle wheels of the type illustrated in T. A. Cooks U. S. Letters Patent No. 296,728; and the objects of my invention are, first, to make the propeller practically applicable to vessels of all kinds and to various depths of water; secondly, to enable it to be used not only as a propeller but as a steering medium and this, moreover, without changing the direction of rotation of its motor; third, to enable it to work even in water containing material which would entangle or obstruct the usual propellers if they were open or exposed.
I have illustrated my invention, in several adaptations thereof, in the accompanying drawings, wherein,
Figures 1 and 2 are diagrammatic views illustratin the propelling and steering operations; ig. 3 is a side view, partly in section, of another form of my invention; Fig. 4 is a horizontal sectional view of what is seen in Fig. 3 taken just above the meeting plane of two parts of a certain gear casing 20; Figs. 5 and 6 illustrate different types of blades or paddles; Fig. 7 shows a construction in which the driving motor is directly connected with the mechanism; Fig. 8 is a view in side elevation, partly in section, of another form of my invention; Fig. 9 is a horizontal sectional view on Fig. 8 taken just above the meeting plane of the parts of the gear casing 20 Fig. 10 is a View in side elevation, partly in section, of substantially the same ind of paddle wheel as is shown in Figs. 8 and 9, in another form.
Referring, first, to Figs. 1 and 2, let 1 designate the main axis of the propeller and 2, 3 and 4 the axes of paddles 6, 7 and 8 arranged equidistantly from each other and from the axis 1, the same being geared together and with the axis 1 in such manner that if the whole system revolves around axis 1 in either direction for a certain number of revolutions each paddle will rotate around its own axis in the opposite direction only half the number of revolutions of the whole. The result will be that each paddle, in rotating around the axis 1, will in each such complete revolution once assume a position in which it lies in a radius from the axis 1, and the point where this occurs will be the same for all the paddles. If the center gear of the train of gearing, i. 0., the gear on the axis 1 remains non-rotary the point at which the blades assume the position stated will never change; but if said gear can be turned in either direction the point referred to may be shifted relatively to the axis so that the blades, as the whole system rotates around the axis 1, can be made to assume the radial position in any radius from axis 1. For instance, in Fig. 1, with the whole system rotating in the direction of the arrow, the blade 8 will exert a rearward pressure as indicated by the arrow leading therefrom, thus propolling the boat forward; in Fig. 2, withthe whole system rotating in the direction of the arrow this being the same direction as in Fig. 1 the blade 8 will exert pressure in the direction of the arrow leading therefrom and therefore propel the vessel rearwardly; and if the gear on 1 is shifted in either direction rotatively, so the point at which the blade 8 will stand in a radius from the axis 1 will be shifted rotatively, thus providing for the blade 8 exerting pressure more or less in a lateral direction, which will of course be then useful in steering.
In carrying out this principle, and referring to Figs. 3 to 6,in suitable brackets 1718 at the stern of the vessel 16 are journaled vertically a hollow shaft 9 inclosing a shaft 1. The propeller comprises blades 6 and 7 each rotatable on its own axis and around the shaft 1, which latter effect is produced by rotating shaft 1 which carries with it the casing 20 in which the gearing for rotating each blade on its own axis is disposed and which forms a part of the rotating structure and in which the blades are individually journaled. The propelling energy may be derived from any suitable source, through a belt, (not shown) adapted to be placed around the pulley 10. 14 is a pulley on shaft 9 which may be suitably connected by an endless belt or the like, (not shown) with the steering wheel (not shown) of the vessel. On an extension of the shaft 9 is a gear 0 within the casing 20 and the blades 6 and 7 have gears 23 and 24 inclosed in the casing and meshing with gear 0. The motor being in operation, as each blade is turned to a radial position with relation to shaft 1 it will exert a pressure and move the vessel and the point at which the blades assume this radial position may be changed for the purpose of steering the vessel by altering, rotatively, the position of shaft 9.
Figs. 5 and 6 show other forms which the blades 6 and 7 may have.
In Figs. 8 and 9 9 is the power shaft and 1 the steering shaft, the latter carrying the gear 0 and the former the gear casing 20.
Except that the pulley 14 is arranged on the shaft 1 and the power is transmitted to shaft 9 from a suitable motor through a shaft 31 and bevel gearing 29 and 30 arranged in the casing 32, the construction here shown is substantially the same as that already described.
In Fig. 7, 9 is the steering shaft and 25 an explosion engine used to drive the power shaft (not shown).
It will be obvious that, as shown in Fig. 10, the arrangement shown in Fig. 8 may be made reciprocal, 1" being the steering shaft and carrying the central gear in the casing 20 so that the construction remains substantially the same. The hollow shaft 9 is much shorter and does not reach higher than the beveled wheel transmission. The tube 9 which in its outward appearance resembles the tube 9 in Fig. 8 does not rotate but forms one piece with the casing 32", the latter being substantially the same as the casing 32 in Fig. 8.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. The combination in a vessel, of a propelling means depending therefrom andbeing free or clear below, said means comprising, a rotary inclosed casing, a plurality of blades orpaddles journaled in said casing, a central gear inclosed by said casing, other gears inclosed by said casing and connecting said blades or paddles with the central gear, each blade being supported at one end in said casing and having its other end free or clear, a shaft, a hollow shaft inclosing said firstnamed shaft, said shafts carrying the one the central gear and the other the casing, and means for rotating said shafts independently of each other, said blades or paddles depending from the casing and being free and clear at the sides and bottoms thereof, substantially as described.
2. The combination of a stationary casing, a rotary inclosed casing arranged below the stationary casing, a hollow shaft penetrating the stationary casing and carrying the rotary casing, bevel gearing, inclosed in the'station ary casing, for rotating said shaft and the rotary casing, a plurality of blades or paddles journaled in the rotary casing, a central gear inclosed by the rotary casing, other gears inclosed by said rotary casing and connecting the blades or paddles with the central gear, a shaft carrying said central gear and penetrating the hollow shaft and means for rotating said last-named shaft, substantially as described.
3. The combination in a vessel, of a propelling means depending therefrom and being free or clear below, said means comprising, a plurality of rotary blades or paddles, a rotary disk-shaped casing, each blade or paddle being journaled at one end in said casing and being free or clear at its other end, gearing in said casing connecting said paddles, and concentric shafts operatively connected the one with said casing and the other with said gearing, substantially as described.
a. The combination in a vessel, of a propelling means depending therefrom and being free or clear below, said means comprising, two or more blades or paddles mounted in flying position upon a rotary disk casing and journaled in said casing, with a gearing in said inclosed casing which rotates said paddles with half the number of turns and in opposite directions of how the whole paddle wheel is rotated around its central axis, the paddle wheel having two concentric shafts as shown, one of which is rotated for propelling and the others for steering, independently of each other, the mean peripheral velocity of the paddle being higher than twice the velocity of the vessel, all substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
LADISLAV voJAcEK.
