Abstract
Abstract A mounting structure for a submerged motor wherein vibrations of the motor are isolated from an external supporting frame. The motor is suspended beneath at least one float member which is attached to a shroud used to direct cooling water over the exterior surface of the motor. Vibration damping means are provided between the shroud and the motor. The vibration damping means are secured to a plurality of vertically extending bars located between the shroud and the motor. The bars are spaced at regular intervals around the periphery of the motor and serve with the vibration damping means to provide vanes which prevent the formation of a vortex.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
127 words
A mounting structure for a submerged motor comprising a. a motor submerged in a liquid, b. shroud means encircling and spaced from said motor and having opposed ends open, c. vibration damping means between said shroud and said motor to isolate vibrations therebetween, d. support means to support said motor and said shroud means, e. said support means including at least one float member, f. said shroud means carrying a plurality of vertically extending bar means and said motor carrying a plurality of vertically extending bar means paired with said bar means carried by said shroud, g. and wherein said vibration damping means is secured to said paired bar means and envelops a substaNtial portion of said paired bar means so as to be loaded in shear.
Claim 2
Dependent Claim
127 words
A mounting structure for a submerged motor comprising a. a motor submerged in a liquid, b. shroud means encircling and spaced from said motor and having opposed ends open, c. vibration damping means between said shroud and said motor to isolate vibrations therebetween, d. support means to support said motor and said shroud means, e. said support means including at least one float member, f. said shroud means carrying a plurality of vertically extending bar means and said motor carrying a plurality of vertically extending bar means paired with said bar means carried by said shroud, g. and wherein said vibration damping means is secured to said paired bar means and envelops a substaNtial portion of said paired bar means so as to be loaded in shear.
Claim 3
Dependent Claim
22 words
A mounting structure for a submerged motor as defined in claim 1 wherein said shroud means is substantially frustoconical in cross section.
Claim 4
Dependent Claim
51 words
A mounting structure for a submerged motor as defined in claim 1 including a propeller driven by said motor, and wherein said vibration damping means secured to said plurality of paired bar means form vanes exteriorly of said motor and serve to prevent a vortex when said motor drives said propeller.
Claim 5
Dependent Claim
26 words
