PROPELLING DEVICE.
SPECIFICATION forming part ofLetters Patent No. 768,33, dated August 23, 1904.
Application filed Nevember 4, l9 03. Serial No. 179,858. (No model.) i
To all whont it may concern:
Be it known that I, OAREYA. MANKER, a citizen of the United States, residing in Pearl, in the county of Pike and State of Illinois, have invented certain new anduseful Improvements in Propelling Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming'part of this specification.
My invention relates to a propelling device for navigable vessels; and it has for its object to furnish a construction of propelling device in which deflecting-plates are utilized in connection with propellers and arranged in such 5 manner forward of the propellers that they will not only exert a tendencyto elevate the vessel in the water, but willalso act to create an upward and backward flow of water to the propeller blades during their ascending propeller-blades are assisted during their upward strokes by the force of water directed thereagainst, and the blades during their downward strokes act with greater force against the water IIl'WhlCll they are moving and exert a lifting action with respect to the vessel to diminish the water displacement, and consequently the resistance of the water to the vessel -hull, as a consequence of which in- 3 creased speed of the vessel is obtained.
The invention consists infeatur'es of novelty hereinafter fully'described, and pointed out in the claims.
Figure I is a side elevation of a vessel equipped with my propelling device, one
member of the keel being omitted and the deflecting-plates being shown in longitudinal section. Fig. II is an elevation looking at the forward end of the vessel shown in Fig.
4 1. Fig. III is a horizontal section taken through the propelling device on line III III, Fig. I.- Fig. IV is a longitudinal section through a portion of one of the deflectingplates. Fig. Vis a section illustrating a modifioation of the deflecting-plates. Fig. VI is a top view illustrating a modification of the defleeting-plates located in close proximity to i the propellers.
As a result of this arrangement the.
Fig. VII is a longitudinal section through the forward end of a modified form of the deflecting-plates.
1 designates the hull of the vessel.
2 represents a pairof keel members located beneath the vessel-hull and having forward knife-edges 3. The keel members are spaced apart, and extending longitudinally between them are upper and lower deflecting-plates 4,
that are preferably formedwith forward knifeedges 5. (See .Figs'Iand IV.) These defleeting plates" are preferably -curved upwardly and forwardly and act against the water in which the vessel moves with a lifting influence and at thesaine time serve to direct the water above them in a rearward course members and so disposed that they are partially in the rear of the water passage-way between the keel members and project partially beyond a line extending along the outer sides of the keel members. By thus position ing the propellers the blades thereof are permitted to partake of their upward'strokes in the path of the water passing between. the keel members and over the deflecting-plates 4:, while the blades on their descending strokes are out of the path of fiow of the water di- 'rected in the course referred to.
8 designatesa pair of oscillating deflectors mounted on shafts extending horizontally and transversely through "the keel members 2. These deflectors are located at the rear of the deflecting-plates 4'and in front'of' the propellers 6. Oscillation is imparted to the deflectors through any suitable means, such as a rotatable operating-shaft 9, (see Fig. L) that is provided with worms 10, that mesh with worm-gears 11, fixed to the deflectorshafts. I
12 represents auxiliary deflecting-plates carried by the keel members 2 and extending horizontally and outwardly from said members. These auxiliary deflecting-plates are preferably concave at their lower sides, as seen in Figs. II and III, so that they receive water beneath them and act to prevent settling of the vessel.
13 is a rudder located at the rear of the propellers 6.
14 is a curved deflector carried by the vessel-hull and located between the keel members 2 at their rear ends, this deflector serving to direct the water inadownwardly course above the upper deflecting-plate 4 instead of permitting it to flow directly in a rearward course above the propellers.
In Fig. V, I have shown a modification of the deflecting-plates 4, in which the plate 4 is illustrated in the shape of an ogee curve instead of being curved in a single direction, as illustrated in Figs. I to IV. By using a deflecting-plate of this form it may take the place of the defiecting-plate 4 and the deflector at the rear of said plate.
In Fig. VI, I have shown a modification in which a deflecting-plate i is utilized in close proximity to the propellers instead'of being located remote therefrom and having a deflector positioned between the deflectingplate and the propellers. In this modification the auxiliary deflecting-plates 12 are positioned in the same perpendicular line as the deflecting-plate a.
In Fig. VII, I have shown a modification in which the forward end of a deflecting-plate designated 4 is of enlarged and curved form, as seen at t, instead of being in the shape of a knife-edge, the enlargement of the plate serving to diminish the space at the entrance ends of the pair of deflecting-plates, so that the flow of water between the plates will be lessened, if desirable.
In the operation of my propelling device the vessel in its forward movement meets with the water in which it floats, and the deflecting-plates receiving the water beneath them tend to ride on the water, and as a consequence the vessel is lifted in the water. This lifting action of the vessel is due to the deflecting-plates being inclined or curved forwardly and upwardly to impinge upon the water. The water flowing over the deflecting-plates between the keel members passes in a rearward course and flows onto and over the deflectors 8 to be directed therefrom to the under sides of the blades of the propellers 6 at the rear of the deflectors, so as to exert force against said blades in an upward direction and assist them in their rotation. An increased force is thereby imparted to the propellers, as aresult of which the propellerblades move downwardly with greater power against the water, and in addition to their screw-propulsion action to propel the vessel act to lift it in the water to diminish the water displacement, so that greater speed of the vessel may be acquired and maintained.
The oscillating deflectors 8 may be rocked vertically to any desired degree to obtain the proper angle of upwardly -directed flow of water therefrom to the ascending propellerblades in order that the water will strike said. blades with the most beneficial force to accelerate their upward travel. The water doflected also acts on the under faces of the descending propeller-blades to furnish better efliciency of operation thereof than it would act if it were not deflected thereto by the described deflecting construction.
I claim as my invention 1. In a propelling device, the combination with a vessel-hull, of a plate located beneath the hull, and a propeller arranged at the rear of said plate to receive an ascending flow of water that passes contiguous to said plate, substantially as set forth.
2.
