Tow for swimmers

Claim 2

A tow for swimmers comprising, a float, an internal combustion engine carried by said float, a propeller drivEn by said engine and a fuel tank for supplying fuel to said engine and means are provided for supplying combustion air to said engine from the interior of said float which is connected with atmosphere, and means for suspending said engine from below said float; said suspending means comprising a streamlined hollow shaft connected to the lower side of the float, a duct casing connected to the lower end of said hollow shaft and housing said propeller, and means for securing said engine to said casing downstream of said propeller.

Claim 3

A tow for swimmers comprising a float, an internal combustion engine carried by said float, a propeller driven by said engine and a fuel tank for supplying fuel to said engine, wherein said float and fuel tank consists of chambers formed in a hollow member by a partition subdividing the interior of said hollow member and said engine is suspended from below said float, first conduit means providing communicating between atmosphere and the interior of said float chamber, and second conduit means providing communicating between the float chamber and the engine for supplying combustion air to said engine, the first and second conduit means being offset such that the float chamber acts as a separator that prevents water accidentally entering the float chamber from said first conduit means from entering said second conduit means.

Claim 4

A tow for swimmers comprising a float, an internal combustion engine carried by said float, a propeller driven by said engine and a fuel tank for supplying fuel to said engine, wherein said float and fuel tank consists of chambers formed in a hollow member by a partition subdividing the interior of said hollow member and said engine is suspended from below said float, first conduit means providing communicating between atmosphere and the interior of said float chamber, and second conduit means providing communicating between the float chamber and the engine for supplying combustion air to said engine, the first and second conduit means being offset such that the float chamber acts as a separator that prevents water accidentally entering the float chamber from said first conduit means from entering said second conduit means.

Claim 5

A tow for swimmers according to claim 2, wherein said float chamber is connected to atmosphere through a snorkle that comprises said first conduit means and a combustion air intake comprising said second conduit means extends from the top of the interior of said float chamber.

Claim 6

A tow for swimmers according to claim 2, wherein an ignition system, carburetor and exhaust system of the engine are sealed off independently of each other.

Claim 7

A tow for swimmers according to claim 2, wherein a sealed carburetor is supplied with air through a bore extending into a the engine and jet means are provided for compensating for reduced pressure differences.

Claim 8

A tow for swimmers comprising a float, an internal combustion engine carried by said float, a propeller driven by said engine and a fuel tank for supplying fuel to said engine, wherein said float and fuel tank consists of chambers formed in a hollow member by a partition subdividing the interior of said hollow member and said engine is suspended from below said float, means being provided for supplying combustion air to said engine from the interior of said float chamber which is connected with atmosphere, and an exhaust system including an acutely angled chamber disposed so as to divide the flow of water into two streams, at least one of the walls of said chamber being provided with a valve having a value plate adapted to be moved into contact with said chamber wall to close an outlet opening therein.

Claim 9

A tow for swimmers comprising a float, an internal combustion engine carried by said float, a propeller driven by said engine and a fuel tank for supplying fuel to said engine, wherein said float and fuel tank consists of chambers formed in a hollow member by a partition subdividing the interior of said hollow member and said engine is suspended from below said float, means being provided for supplying combustion air to said engine from the interior of said float chamber which is connected with atmosphere, and an exhaust system including an acutely angled chamber disposed so as to divide the flow of water into two streams, at least one of the walls of said chamber being provided with a valve having a value plate adapted to be moved into contact with said chamber wall to close an outlet opening therein.

Claim 10

A tow for swimmers according to claim 6, wherein a branch pipe extends from the exhaust system into the storage tank above the level of the fuel in said tank.
