IMPROVEMENT IN PROPELLING- APPARATUS.

The Schedule referred to in these Letters Patent and making pert ofthe same.

Toall whom it may concern Be it known that I, CORNELIUS SCHILLING, of the city, county, and State of NewYork, have invented a new and improved Propeller; and I do hereby declarethe following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing Figure 1 represents a longitudinal vertical section of this invention.

Figure 2 is a plan or top view of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a propeller-blade, which is attached to a lever suspendcd from two rods, which are connected by an intermediate link, and one of which is attached to a crank, while the other is pivoted to a standard or bracket, in such a manner that, by imparting to said crank a revolviug motion, a compound oscillating motion is imparted to the propeller-blade, causing the same to dip down into the water, swing forward, riseout of the water, and swing backward, and by these means a vessel can be propelled with ease and facility.

The propelling mechanism is mounted on a platform, to which a revolving motion can be impart-ed by a pinion mounted on an upright shaft, and gearing in a stationary segmental rack, in such a manner that, by turning the upright shaft, the direction in which the propelling mechanism acts can be changed at pleasure, and the vessel can be steered with ease and facility. A sliding keya'nd perforated disk serve to stop the platform in the desired position.

In the drawing-- The letter A. designates a circular platform, which is fitted into cavity at or near the stern of a vessel, and which is retained in position by a center pin, a, so that it can be freely revolved in either direction.

Suitable fi-iction-rollers, b, inserted in the under surface of the platform, facilitate the revolving motion of the same.

From this platform risetwo standards, B, which form the hearings for the crank-shaft O, and from the crank 0 extends a rod, (1,130 the outer end of which is pivoted the level-D, carrying the propeller-blade e. p

' From the platform A also extends a bracket, E, from which extends a rod,jc, to the propeller-lever D, said rod being pivoted at one end to the bracket and at the opposite end to the lever, as shown in fig. 1

The rods (1 and c are connected by a link, 1; which tands parallel to the lever D, and serves to sustain the rods (1 a in any position into which the same may be brought by the revolution of the crank 0.

By imparting a. revolving motion to the crank-shaft, the blade 0 assumes a compound oscillating motion, whereby the same is raised out of the water, carried forward, then depressed and carried back in the di rection opposite to that in which the vessel is to he propelled. This action of the propeller-blade remains the same in whatever direction the crank-shaft is turned, with that exception, that in every case the vessel is propelled in a direction opposite to that in which the blade 0 is carried through the water, and this directionis reversed when the mot-ion'oi' the crank-shaft is reversed.

In the platform A is secured an upright'shaft, It, on the lower end of which is mounted a pinion, i, which gears in a segmental rack, j, fastened in'the circumference of the cavity of said platform, and to the upper end of the shaft It is secured a hand-wheel, It, as shown in fig. 1. By turning this hand-wheel the platform, together witlrthe propelling mechanism, is rotated, and the direction in which the propeller acts can thus be changed at pleasure. The

blade 0, therefore, acts as'propeller and also as the rudder.

Through the baud-wheel It extends a key, I, the lower end of which can be made to catch in one'of the holes of a perforated disk, in, which is secured to or forms a portion, of the platform A. By means of this key the platform can be locked in any desired posi tion, but if it is desired to change the direction of the propeller, the key must be raised and the hand-wheel revolved in the requisite direction.

This propeller is intended particularly for canalboats, but it can also he used with advantage for other vessels, and it can be driven by steam or any other suitable p'ower.

What I claim as new, and desire to secure by Letters Patent, is-

1. The lever I), carrying the blade e, and secured to rods d c, in combination with the link f, the crank c, and the'platform A, substantially as shown and described.

2. The pinion i and rack j, in combination with the platform A, rods (1 0', link 1, and lever D, carrying the blade a, substantially as set forth.

This specification signed by me this 25th day of June, 1870.
