UNITED' STATES.
PATENT @erica MAXIMILIAN wAPPIcH; oF sAoRAMENro, CALIFORNIA.
llVlPROVED MARINE PROPELLER.
Specification forming part of Letters Patent No. 33,459, dated October 8, 1861.
To all whom it may concern.-
Be it known that I, MAXIMILIAN WAPPICH, of Sacramento, in the State of California, have invented certain new and useful Improvements in Propelling Ships and other Vessels; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and marks thereon.
Of the drawings, forming part of this specification, Figure 'lis a side view of a vessel having my improvements aixed thereon, and Fig. 2 an end or stern view of the same.
In each of these figures where like parts are shown like letters and marks are used to indicate them.
My invention relates to the position of the propeller-shafts and to the character and arrangement of the propellers thereon; and my invention consists in placing apropeller-shaft on each side of the vessel, either in a recess formed therefor or in such recess as the run or like recess usual in vessels between the stern or rudder post and the line of the greatest width of beam of the vessel, and in attaching to the propeller-shafts two or more propellers the edge or periphery of which will be in the line of a cone directed from the front to the rear end of the shaft, the screw being of two or more threads cut upon a-cylinder, then the cylinder turned to a cone, and sections thereof used as propellers.
The drawings show the propeller-shafts a extending backward and terminating at the rudder-post, thus having the propellers b in the run of the vessel. The shaft is shown in the line of the run or parallel to the line of the keel; but the shaft may be in any other line desirable, and the propellers may be placed in the run of the vessel or in any recess between the rudder-post and the greatest width or beam of the vessel. The propellers may be entirely or partly submerged. The rear end of the shaft ca-n be supported on suitable bearings c, sustained by bracesd attached to the vessel. The packing for the shaft I prefer to be that described in a pat-ent granted to me on the 27th day of May,1860.
Grating or other suitable frame-work may be placed around the propellers, for protectlng them from contact with any material or substance that otherwise might injure them.
The propellers are shown with four blades f' e, each blade being an extension from the hub f, which was the interior of the cylinder. This can be secured upon the shaft by any means ordinarily used in attaching propellers to shafts. The rear part of the blades of the propeller is shown extending beyond the hub. Any number of blades less or greater than four may be used. y
The advantages of my improvements are that the p ropellers will work in comparatively undisturbed water, and that in their revo lution they will draw a solid body of water against the hull, thus keeping the vessel buoyant and filling cuntinuously up the wake of the ship, creating an impulsive current against the ship and giving the greatest facilities for her minding the helm.
The construction of the propellers as described has advantages over any yet invented, it being a natural screw continually increasing in circumference. This produces benefits that cannot be obtained by an increased pitch and without any of the defects thereof. These several propellers upon the shafts will accomplish the most effective forward propulsion and prevent all slip, as each blade will take a newV effective hold on the water, and by creating a current against the run of the ship give thc'succeeding propeller a quick and full supply of water to work in.
The guards or gratings around the-propellers may be permanentlyattached to the vessel, or they may be detachable.
I am aware that the principle of placing one propeller in the dead-wood or perpen` dicular 0r parallel with the keel either in a recess or space between the rudder-post and rudder, as in Lapus patent, or the propeller aft the rudder, as in Ericssons patent, is not new. I am also aware that two propellers aft the stern have been used, and that it has been suggested to apply several wheels to the middle, body, or cylindrical part of boats, and thereforelhave no claim to anyofthese plans; but
that I do claim is- Placing propeller-shafts on each side of the vessel between the greatest width or beam and the rudder-post, the shafts being supported by bearings from the stern and hav- `ing propellers whose blades increase in diam-l Witnesses: I
