Abstract
Abstract System for boats having compressed-air means for providing propulsive power by way of nozzles, of which swingable ones are provided in the stern and optional, stationary ones in the bow. Articulated conduit sections allow the stern nozzles to be swung about considerable angles, thereby controlling the direction of movement of the boat, while speed control may be provided through conventional throttle means which are operable independently from steering means which act upon the swinging movement of the nozzles. The nozzles in the bow can be used for braking forward movement and to provide rearward movement of the boat; they may be closed by flaps when not in use.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
A combined driving, steering and braking system for boats, comprising in combination means for producing, storing and dispensing compressed air, and rearwardly directed compressed-air nozzles in the stern of the boat, operatively connectable with said compressed-air means, and having terminal portions swingable in a substantially horizontal plane, by the intermediary of respective articulated conduit sections, the latter being connected by the aid of transmission means to manual steering means at a control position of the boat, for controlling the swinging movement of said nozzles and thereby the direction of movement of the boat, as well as forwardly directed stationary compressed-air nozzles in the bow of the boat, operatively connectable with said compressed-air means, and adapted to brake the forward movement of the boat and to provide rearward movement if necessary, said stationary nozzles being lodged in recesses provided in the bow of the boat, and further comprising movable flaps for said recesses, and control means for selectively opening and closing said flaps from the control position of the boat, thereby reducing resistance to the water during the forward movement of the boat when said stationary nozzles are not activated and said flaps are closed.
Claim 2
Dependent Claim
194 words
A combined driving, steering and braking system for boats, comprising in combination means for producing, storing and dispensing compressed air, and rearwardly directed compressed-air nozzles in the stern of the boat, operatively connectable with said compressed-air means, and having terminal portions swingable in a substantially horizontal plane, by the intermediary of respective articulated conduit sections, the latter being connected by the aid of transmission means to manual steering means at a control position of the boat, for controlling the swinging movement of said nozzles and thereby the direction of movement of the boat, as well as forwardly directed stationary compressed-air nozzles in the bow of the boat, operatively connectable with said compressed-air means, and adapted to brake the forward movement of the boat and to provide rearward movement if necessary, said stationary nozzles being lodged in recesses provided in the bow of the boat, and further comprising movable flaps for said recesses, and control means for selectively opening and closing said flaps from the control position of the boat, thereby reducing resistance to the water during the forward movement of the boat when said stationary nozzles are not activated and said flaps are closed.
Claim 3
Dependent Claim
29 words
The system as defined in claim 1, wherein at least said swingable portions of the nozzles are lodged in substantially horizontal recesses provided in the stern of the boat.
Claim 4
Dependent Claim
47 words
The system as defined in claim 1, wherein both said rearwardly and said forwardly directed nozzles are disposed substantially at the same level, and wherein at least said rearwardly directed nozzles are positioned, with their swingable portions, so as to be within the contour of the boat.
Claim 5
Dependent Claim
40 words
A The system as defined in claim 1 wherein said transmission means includes force transmitting means operatively interconnecting said steering means with portions of said articulated conduit sections for simultaneous swinging movement thereof about an angle of at least 45*.
Claim 6
Dependent Claim
35 words
The system as defined in claim 4, wherein said compressed-air means includes throttle means providing speed control for the boat, operable independently from said steering means and the prevailing direction of movement of the boat.
