Letters Patent No. 97,146,
datedlvoeember 23, 1869.
rmrnovEMnNT 1N reconnues-APPARATUS.
The Schedule referred to in these Letters Patent and making part of the same.
Be it known that I, JOSEPH F. ALEXANDER, of the city, county, and State of New York, have invented a new and improved Undulating Propeller; and I do hereby declare the following' to be a full, clear, andA exact description thereof', which will enable those skilled in the art to uiake'and use the same, reference being had to the accompanying drawing, forming part of this specication, in which drawing- Figure 1 represents a longitudinal vertical section of this invention.
Figure 2 is asimilar view thereof, showing the propeller in a different position from the previous ligure.
Similar letters indicate corresponding parts.
This invention consists in the arrangement of a bucket or blade, working in -a chamber which is open at both ends, and extends inthe direction of the keel of the vessel to be propelled, said blade being suspended at its ends from two cranks, situated at an angle of ninety degrees to each other, in such amanner, that by revolving the crank-shaft, an undulating' motion is imparted to said blade, whereby the water in the propeller-chamber is displaced, and expelled either at one or the other end of said chamber, according to the direction in which the `crank-shaft is turned,- and thereby the vessel is propelled either forward or backward, with comparatively little expenditure of power.
The letter Adesignatcs a shaft, to which a revolvmotor, and which has its bearings in suitable boxes, in thev interior of the vessel to be propelled, said shaft being placed in line with or parallel to the keel of the vessel.
On this shaft are secured two cranks B C, at-an angle of ninety degrees (or nearly so) to each other, and each of these cranks connects by a rod, l) o r c,
'lhese cross-heads move in suitable slides D, and they connect, by rods g h,1with the ends i. j of a bucket or blade, E, which is enclosed in the propellerchamber F.
This chamber is situated below the water line, either in line with or parallel to the keel of the vessel to be' propelled, and it is open at both ends, as shown in the drawings.
IThe edges of the blade E extend close to the sides volved, the water contained in said chamber is displaced and forced out at one of the ends of the chamber, according to the direction in which the vessel is to be propelled.
If the shaft is turned in the direction .of the arrow marked on it in iig. l, the blade E will movefrzom the the water contained in said chamber' is forced out in the direction of the arrow marked in the chamber in iig. 1.
Dit the motion of the shaft continues until the end of the blade `E reaches the top of the propellingchamber, the end j .will be brought again to the centre of said chamber, and the water will continue to bc displaced in theI direction of the arrows marked in said chamber in fig. 1, and the vessel will be propelled in the direction opposite to said arrows.
li' the motion of the shaft-A is reversed,vas indicated by the arrowmarked thereon in g. 2, the water in the chamberl F will be displaced in the direction of the arrows marked in said chamber in fig. 2, and the motion of the vessel will be reversed.
The effect of the blade E to expel the water from the -charnber F, either in one or the other directiolnwith out interruption during its entire motion, is due to the position of the cranks B G at rightangles to each other.
If these cranks were placed at angles of one hundred and eighty degrees to each other, the Water, during one half of the stroke of said blade, would be exlpelled at one, and during'the other half, at the opposite end of the chamber l", and'if the :cranks B'U were placed in the same directioln'the Water would be expelled from the chamber' F simultaneously at both ends; but by placing the cranks at an angle of ninety degrees, the blade receives an undulating motion of vsuch anature that the water will be continually expelled either at one or at the other end of the chamber' F.
The joints at the ends of lil and j of the blade are double, as shown, so that the blade E is free -to accommodate itself to the .positions of the rods g h.
It must be remarked that two or more propeller'- hlades can be applied either' in the sides or at the stern of one and the same vessel, and said blade or `bladesmightbe worked freely in the water without any chamber, and it or they can be placed either ina vertical or horizontal position, and applied to any part v described.
