Description
AUGUSTIN DUBOCE, OF BROOKLYN, NEW YORK.
PROPELLER.
Specification of Letters Patent No. 13,336, dated July 24, 1855.
To all whom it my concern:
Be it known that I, AUGUSTIN DUBooE, of Brooklyn, Kings county, and State of New York, have invented a new and useful Improvement in Propellers for Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1, is a plan'of the mechanism for operating the propellers; Fig. 2, a vertical cross section of the vessel with the propellers and their mechanism; Fig` 3, an elevation of one of the propellers; and Fig. 4L, a horizontal section of the propellers representing the several positions they assume in their vibrations.
The same letters indicate like parts in all the figures.
The propellers which I employ are paddles or blades suspended at, and from the sides of the vessel, and vibrating laterally in the vertical plane of a cross section of the vessel and at the same time having a reciprocating rotary motion on their own axis, so that at the extremity of each lateral vibration they shall be feathered, that is have their planes in the line of motion of the vessel, and in vibrating either way turn on their axls that their faces may be oblique to that line of mot-ion for the purpose o-f giving the propelling or sculling action, and toward the end of each lateral motion again turn in the line of the vessels motion. And my said invention consists in giving to each blade the two motions above indicated, that is the vibratory motion in the plane of a. vertical cross section of the vessel, and the reciprocating rotary motion on its axis by jointing the arbor of the blade to the vessel with a ball and socketjoint or its equivalent, in combination with an arm projecting from the said arbor above its ball and socket joint, the end of which arm is connected by a slipping and ball and socket joint, or the equivalent thereof, with a wheel or crank arm on the driving shaft, the arbor of the blade being kep-t in the plane of the vert-ical cross section by suitable guides or their equivalent, whereby, as the driving shaft rotates, the end of the arm at its connection with the slipping and ball and socket joint is made to describe a circle which imparts to the blade the lateral vibratory motion toward and from the vessels side as well as the reciprocating motion on its axis to reverse the direction of its Obliquity, this lat-ter motion being mainly imparted to the blade at the end of each lateral vibration by reason of the passage of t-he end of the arm at the upper and lower dead point of the crank like motion.
In the accompanying drawings a represents a portion of a vessel, and Z), b two blades or sculls, one on each side, although the number can be increased at pleasure. The form of the blade represented in the drawings is the one which I prefer, but it may be changed at the pleasure of the constructor.
The upper end of the blade has an arbor c which passes through a sleeve arbor Z to which it is properly secured to turn therewith. And the lower end of this sleeve is of a spherical form fitted to a socket c in the side of the vessel to constitute what is well known as a ball and socket joint. And as t-he arbor of the blade passes through to the inside of the vessel the ball and socket joint must either be placed sufficiently above the water line or the joint itself should exclude water. The upper end of the sleeve arbor turns in a box f fitted to slide between guide ways g, g which insure the vibration of the blade in the plane of a vertical section of the vessel.
There is an arm h which projects inward from the sleeve arbor and between the guide ways and the ball and socket joint and in a plane at right angles to the face of the blade. The extreme end of this arm constitutes a cylindrical .wrist pin fitted to slide freely but accurately in the cent-ral hole of a ball z' which is fitted to a spherical socket I near the periphery of a wheel on the crank shaftlo of an engine, there forming a sliding and ball and socket joint, so that the end of the arm, thus jointed, revolves in a circle, thereby causing the paddle to vibrate toward and from the side of the vessel in a vertical or nearly vertical plane at right angles to the vessels keel, and also to rotate on its axis alternately in opposite directions to incline the plane of the blade to the line of the keel, and alternately to reverse that angle, the degree of ultimate inclination in either direction depending upon the length of the arm relatively to the distance of the center of the ball and socket joint in which the arm works from the center of the crank or driving shaft.
From the foregoing it Will be seen that when the end of the arm is at the highest part Of its circuit the blade will be nearest 1 the side of the vessel, with its plane parallel with the keel, so that it will pass through the water with the least resistance, as represented by the lines Z, Z, see Fig. 4, and when the arm is at the lowest part of its circuit the blade will be farthest from the vessel and with its plane also parallel with the keel as represented by the lines m, m, see Fig. 4. And it will also be seen that the turning of the paddle tO reverse the Obliquity will take place mainly at the end of each vibration when the point Of connection of the arm is passing the upper and the lower dead points, so that during the greater part Of the lateral vibrations of the paddle its Obliquity is such as tO give an efficient propelling action, and when it has but little vibratory motion it is feathered to cut through the water.
I/Vhen the crank Or driving shaft rotates in the direction of the arrow the Obliquity of the blade will be such during the vibration as to force the vessel forward; but when the motion Of the shaft is reversed the Obliquity of the paddles is4 also reversed which will give the propelling action in the opposite direction tO back the vessel.
The mechanism is the same on both sides. The blades may be placed anywhere along the sides of the vessel, although I prefer to place them near the stern.
What I claim as by invention for giving the blades the motions above specified, is-
Connecting them with the sides Of the vessel by means Of a ball and socket joint, Or any equivalent therefor, in combina-tion with an arm projecting from the arbor of the blade, the end Of which arm is connected by a sliding and ball and socket joint, or any equivalent therefor, With a wheel or crank arm on the crank or driving shaft, substantially as and for the purpose specied.
AUGUSTIN DUBOCE.
