Abstract
Abstract Water propeller drive for amphibious vehicles with pairs of bow and stern propellers each associated with a corner of the vehicle body and arranged in bights of the body that are adapted to the current conditions, with steering means for adjusting the directional effect of the four propellers that permit steering of all propellers or a selected number of them optionally by means of one or two operating devices for which purpose suitable coupling and uncoupling means are provided in the steering transmission components.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
Marine drive means for amphibious vehicles comprising a vehicle body having four corner areas defining bights adapted to current flow conditions and equipped with two bow and two stern propelling means and separate coupling means between said two bow propelling means and between said two stern propelling means, steering means for moving said four propelling means into directions of travel effectiveness including at least one operating device to optionally steer any desired number of said propelling means and steering transmission means including coupling and uncoupling means intermediate said two bow and said two stern propelling means permitting independent operation of a pair of bow and a pair of stern propelling means.
Claim 2
Dependent Claim
111 words
Marine drive means for amphibious vehicles comprising a vehicle body having four corner areas defining bights adapted to current flow conditions and equipped with two bow and two stern propelling means and separate coupling means between said two bow propelling means and between said two stern propelling means, steering means for moving said four propelling means into directions of travel effectiveness including at least one operating device to optionally steer any desired number of said propelling means and steering transmission means including coupling and uncoupling means intermediate said two bow and said two stern propelling means permitting independent operation of a pair of bow and a pair of stern propelling means.
Claim 3
Dependent Claim
18 words
Marine drive means in accordance with claim 1 including a horizontally disposed axle for each said propelling means.
Claim 4
Dependent Claim
140 words
Marine drive means for amphibious vehicles comprising a vehicle body having four corner areas defining bights adapted to current flow conditions and equipped with two bow and two stern propelling means and separate coupling means between said two bow propelling means and between said two stern propelling means, steering means for moving said four propelling means into directions of travel effectiveness including at least one operating device to optionally steer any desired number of said propelling means and steering transmission means including coupling and uncoupling means intermediate said two bow and said two stern propelling means permitting independent operation of a pair of bow and a pair of stern propelling means, and coupling means in the sidewalls of said vehicles associated with distributing gears connected to said steering means operative to transmit the steering movements from one vehicle to another.
Claim 5
Dependent Claim
140 words
Marine drive means for amphibious vehicles comprising a vehicle body having four corner areas defining bights adapted to current flow conditions and equipped with two bow and two stern propelling means and separate coupling means between said two bow propelling means and between said two stern propelling means, steering means for moving said four propelling means into directions of travel effectiveness including at least one operating device to optionally steer any desired number of said propelling means and steering transmission means including coupling and uncoupling means intermediate said two bow and said two stern propelling means permitting independent operation of a pair of bow and a pair of stern propelling means, and coupling means in the sidewalls of said vehicles associated with distributing gears connected to said steering means operative to transmit the steering movements from one vehicle to another.
