Specification of Letters Patent.
Patented Aug. 27, 1907.
Application filed December 8,1906. sol-a1 No. 848,873.
To all whom it may concern:
Be it known that I, Fnnnnnrcx W. Onomo, a citi zen of the .United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Screw-Propellers, of which the following is a specification. i a
The primary object of my invention is toincrease .the efficiency of screw propellers for marine propulsion without a corresponding increase of the power required to operate them. I
Numerous other advantages accrue from its use some of which are set forth in the specification.
I attain my objectin the manner illustrated inthe accompanying. drawing in which typical propeller blades embodying my invention are shown.
Figure 1 is a face view of one form. of my improved propeller; Fig. 2 a view partly in section, of a modification of the structure of Fig. 1; Figs. 3 and 4 views partly in section' of structural modifications of my improved propeller and Figs. 5 and 6 are sectional views of further structural modifications.
The propeller blade maybe of any suitable or desired size, shape, material or coristmction and 1 form -interior 4 of the blade 3. This passage is preferably closed at its outer end as shown 2. In practice a' hollow shaft is used on account of its strength and lightness. This hollow blade 3 is provided with an outlet or outlets preferably on one of its faces. These outlets may be of any desired form, number or arrangement. I show a single crescent opening 5 in Fig. 2 and the plurality of circular apertures 6 in Fig.
' 1. These apertures may. be protected by a lip 7 to amist in the pumping action. As shown in 3 the blade is cast around the pipes 8 having outlets on the face-of the blade and inlets at the hub.
In 4 the fluid passages are cast inthe blade and extend from the hollow hub to one face.
InFig. 5channelsare castin the blade andth pipes laid therein.
InFig. 6channels10arecastinthefaceand the cover plate 9 issecured thereover.
In operation the fluid passage 2 of the shaft l is connected with any source of fluid supply. Ina boat an intake pipe would be run out at the bow and carried through the condenser of a steam engineer the cooler of a gas engine. thence to the passage 2. On revolving the shaft and propeller in either direction fluid is drawn at the bow thereby assistirigto relieve bow pressure, circulates through the condenseror cooler and finally is discharged through the opening or openings in the blade where it tends to relieve or decrease the vacuum ordinarily caused by the rapid rotation of the screw propeller. If desired a small turbine for power purposes may be installed along the pipe line I claim 1. A screw propeller blade having a fluid passage therein provided with an outlet in one face thereof and slip on the face of the blade adjacent to the outlet.
2. A screw propeller blade having a plurality of fluid passages therein each of which is provided withun outlet in the face of the blade and'a lip on the face ot the blade adjacent to the outlet.
3. A hollow screw propeller blade having an outlet in the face thereof and a lip on the face of the blade adjacent to the outlet.
4. A hollow screw propeller blade having a plurality of outlets in the face thereof and lip's'on the face of the blade adjacent to each of said outlets.
5. A screw propeller comprising a hollow shaft closed at the outer end, a plurslityof hollow blades thereon in open communication with the interior of the shaft, outlets in the faces of the blades and lips on the faces of the blades adjacent to the outlets. I 4
In testimony whereof lhave aflixed my signature in presence of. two witnesses.
