Specification of Letters Patent.

Patented May 14, 1907.

Application filed February 5.1907. Serial No. 365,862.

To all whomit may concern:

Be it known that I, AMEDEE FAYOL, a citizen of the Republic of France, residing at Bordeaux, 9 Rue Matignon, in the Republic of France, engineer, have invented certain new and useful Improvements in Boats, of which the following is a specification.

My invention relates to improvements in propeller ships and has for its object to construct a device of this character so as to be provided with longitudinal keels and to carry, between the said keels, one ormore screw propellers, actuated by a motor or engine mounted on a frame above the water. The floating of the apparatus is insured by means of either an aerostat or of freely revolving floating cylinders, or both these means at one and the same time.

One embodiment of my invention is shown in the accompanying drawings, in which:

' Figure 1 is a longitudinal sectional view of the propeller ship; Fig. 2 is a transversal sectional vilgw of the same; and Fig. 3 is a plan The main frame of the apparatus is comosed of two secondary lateral vertical fiames 1 braced at the top by cross pieces 2, and carrying at their lower portion longitudinal keels 3 designed to insure the rectilinear movement of the propeller. Two of the cross pieces 2 also carry a as a cage or well 5 in w screw propeller 6. The latter, axial line of the apparatus, keels, is actuated by means of located in the between the a motor or en 4, and through the medium of sprocket or other suitable gearing 8.

At the front and rear of the ship are located floating cylinders 9 revolving freely around their axes 10 carried by the lateral frames 1. On the platform 4 loosely rest two casings 11 designed to receive the passengers, the goods, and the like, and forming a double supporting body for such passengers and goods. The said casings are preferably assembled the one with the other by rigid cross-pieces 12.

To steer the ship, use is made of the rudthe keels 3 and which can be actuated from the platform 4, on which the steerer stands, through the medium of sprocket, cord, pull, or other suitable gearing. The motor or engine being in operation, the screw propeller is revolved, and

latform 4, as well iieh is mounted a I produceskthehpropulsion of the apparatus. The efliciency of the screw propeller is as high as it possibly can be because the apparatus offers no obstacle at all to the motion of the water either at the front or rear of the screw propeller. On the other hand, the cylinders 9 revolve in moving forward and, as they are absolutely loose on their axes, they take a tangential speed equal to the speed of the propeller itself. The resistance o posed by the said cylinders is of very sma l extent as they are absolutely smooth and havenoagitating effect on the water; the saidresistance is all the smaller as through the effect of the speed the cylinders are raised up and glide so to say on the surface of the water. Such being the conditions, the result is that the ship can easily reach very high speeds. The peculiar mounting of the casings 11, on the platform 4 allow of their becoming immediately detached from the ship in case the latter should, by reason of the bursting of one of the floating casings or the like, sink in the water, so that the passengers would remain above water.

The number of the floating cylinders, the number of the screw propellers, the position of the latter, as well as the minor details-of the construction of the apparatus, may be varied without departing from or sacrificing any of the advantages of this invention.

Any number of keels may be used and screw propellers may be located either in all the intervals between the keels or in certain intervals only. If only a single keel is used, screw propellers will be located symmetrically at both sides of the said keel. Of course, the motor of the screw propellers may be actuated by any motive power, even by human power, and instead of a single motor for actuating one or several screw propellers, there may be arranged as many motors as screw propellers or a different number.

Claims.

1. A ship comprising the combination of a frame having parallel keels of floats mounted in the said frame both in front and at the rear, a screw propeller carried by the frame between. the keels and at a lower level than that of the floats, a platform on. the frame, a motor or engine secured on the said platform, and a supporting body for passengers and goods loosely located on the platform.

2. A ship comprising a frame having parallel keels, floats mounted in the said frame I a platform on the frame, a cage or Well suspended underneath the said platform, a screw propeller mounted in the cage or Well, a-motor or engine in the middle of the platform adapted to actuate the screw propeller,

and a supporting body for passengers and goods comprising two casings loosely located on the platform alongside the motor or enlo gine, and cross-pieces or braces connecting the said casings other.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of tWo subscribing Witnesses AMEDEE FAYOL.
