PROPELLING MEANS FOR- MOTORS.
Application filed August 6, 1918.
To all whom it may concern:
lle it known that I, PRESLEY B. McCHns- NIGY, a citizen of the United States, residing at Princeton, in the county of Caldwell,
State of Kentucky, have invented a new and;
useful Propelling Means for Motors; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others slrilled in the art to which it appertains to make and use the same.
This invention relates to an improved current motor, that is a screw propeller, and the object of the invention is to mount the screw propeller in bearings at the bottom of the current and provide the same with gear connections to an electric generator, which is mounted upon the side or shore of the stream, for generating electricity, which may be transmitted through suitable wires or leads to various electric motors for furnishing power.
The invention further aims to provide a current motor consisting of a screw propeller having spirally arranged sectional blades.
The invention further aims to provide means for interconnecting the sections of the spiral or screw blades, whereby the sections may be easily removed for the insertion of new sections, thereby renewing the propeller.
In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.
The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings and claimed.
in the drawings Figure 1 is a plan view of the improved current water motor showing the application of the same and constructed in accordance with the invention.
Fig. 2 is a longitudinal sectional view on line 22 of Fig. 1.
Fig. 3 is an enlarged detail perspective view showing how the sections of the blades of the screw propeller are interconnected and secured to the shaft of the propeller.
Fig. 4 is a detail perspective view of one of the end sections of the propeller blades.
Fig. 5 is a detail perspective view of another of said sections of the blades.
Referring more especially to the drawings, 1 designates a base, which may be anchored in any suitable manner in the bed of Specification of Letters Patent.
Patented Aug. 10, 1920.
Serial No. 2428.534.
the stream of water, and rising upwardly from this base are uprights 2 and 3, in bearings of which a propeller or current motor shaft 2: is journaled. One end of this shaft is provided with a universal connection 5 to a shaft 6, which in turn has a universal connection 7 with a shaft 8, which is mounted. in a bearing 9, stationary in any suitable place on the shore 10 of the stream of water. The shaft 8 has a bevel gear 11, and also mounted stationary on the shore of the stream is an electric generator 12, the shaft 13 of which having a bevel gear 1 1 which meshes with the bevel gear 11. By means of suitable wires or loads 15, current may be transmitted to any suitable location for operating electric motors (not shown), for running or operating other machinery. The propeller or motor shaft l has secured thereto by means of the pins 16 collars 17, to prevent axial movement of the shaft 4. Screw propeller blades arranged. spirally are carried by the shaft l. These blades 18 consist of a plurality of interconnected sections 19. These sections are interconnected by the hinged joints 20. To form these hinge joints, it is obvious that one end of each section is provided with a pair of spaced sleeves 21, and its other end with a single sleeve 22, whereby either section may be used at the ends or the center of the blade. It is further obvious that the single sleeves engage between the spaced ends of the sleeves 21, so that the screw pins 23 may pass through said sleeves. The inner threaded ends of the screw pins are threaded into the propeller or motor shaft 4 as shown 24:. so as to hold the blades to the shaft.
Where the spaced sleeves 21 engage the screw pins at the ends of the blades, filler sleeves 25 are disposed between the sleeves 21. Filler sleeves 26 are arranged on either side of the single sleeves 22 at the opposite ends of the propeller blades. These filler sleeves 25 and 26 insure a more rigid construction. A modified propeller blade section 19 is disclosed in Fig. 4, in which there is shown the two end sleeves 27 at one end of the section and a single elongate sleeve 28 at the other end. This form of section may be used at the ends of the propeller blades, instead of using the filler sleeves.
The invention having been set forth what is claimed as new and useful is In current water motor, the combination with a base, of a screw propeller havdially disposed in relation to the shaft, said 7 blades each comprising a plurality of detachable removable sections, said sections having their ends radially, disposed in relationto the shaft center, the ends of said sections being .PIOVlClGCl with insterengaging 10 rolls and notches and radially disposed bolts passing through said rolls and having their inner ends detachably secured in the shaft.
In testimony whereof I have signed my name t this specification in the presence of two subscribing Witnesses.
