1 Claim.
This invention appertains tonew and useful improvements in propulsion means for marine vessels.
The principal object of the present invention is to provide a multiple propeller assembly for single power plant vessels.
Another important object of the invention is to provide a multiple propeller assembly for single power plant vessels in which the speed of the propeller unit is'increased by gearing over the turning speed of the power plant.
Other objects and advantages of the invention will become apparent to the reader of the following description.
In the drawings:
Figure 1 represents a fragmentary top plan View showing a power plant and the propeller assembly.
Figure 2 is a fragmentary vertical sectional view through the hull of a vessel showing the propeller assembly and power plant.
Figure 3 is a diagrammatic view showing the gearing arrangement. I
Figure 4 is a fragmentary detailed sectional view showing one of the driven shafts. f
Figure 5 is an elevational view of one of the bearings.
Figure 6 is a side elevational view wheel and ring gear.
Figure 7 is an outside rear elevational view of the stern of the boat.
Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1 that numeral 5 denotes the stern portion of a of the flymarine vessel and consistent with one practical embodiment of the present invention, this por- The propeller shafts l2 and M are rearwardly diverged with respect to the axially disposed shaft l3, but each of these shafts extends through a bearing structure l6 located upon a stand ll suitably secured to the bottom of the boat or to some supporting structure in the boat.
The forward, end of each of the shafts I 2, l3 and I4- is equipped with a beveled pinion I8 meshing with the ring gear I I] as in the manner substantially shown in Figure 1.v The arrange ment of these pinionsis substantially shown in Figure 3, it being shown that the lowermostpinion l8 meshes with the lower portion'of the ring gear l0 while the remaining pinions I8 mesh with the ring gear ill at diametrically opposite portions of the ring gear substantially ninety degrees removed each from the-lowermost pinion Thus it can be seen, that the single power plant 1- drives three propellers and the speed of I these propellers is increased over the speed of rotation of the drive shaft 8 by the speed increasing gears I0, l8. This arrangement econo- V mizes on space and also on power.
While the foregoing specification sets forth the invention in specific terms, it is tobe understood that numerous changes in the shape, size and materials may be resorted to without departing 7 from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
A propulsion apparatus comprising a power plant, a flywheel driven by the power plant; a
tion of the vessel has three openings therein, in
l2, l3 and I 4, each extending through a corre-' sponding bushing 6 in the stern of the boat and being equipped at its rear end with a propeller l5. I
ring gear on the flywheel, a plurality of stem directed propeller shaftsdisposed in rearwardly diverged relation with respect to eachother and including a. pair of shafts upon opposite sides of said gear, respectively, and a lower shaft at the bottom of said gear, each of the shafts provided with a propeller, and beveled pinionsat the remaining ends of the shafts in mesh with the ring gear, and bearing stands through which shafts are journaled.
