Abstract
Abstract This disclosure relates to a transmission for a small boat including a hull, an engine mounted on the hull, the engine having a crankshaft, and an impeller having an impeller shaft journaled by the hull. The transmission includes an intermediate shaft positioned between the crankshaft and the impeller shaft, a pair of coupling joints angularly movably connected to both ends of the intermediate shaft and connected to the crankshaft and to the impeller shaft. A bearing is connected to the intermediate shaft between the ends thereof, and a resilient mount is connected to the bearing and mounted on the hull for elastically journaling the intermediate shaft on the hull.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A transmission for a small boat including a hull, an engine mounted on said hull, said engine having a crankshaft, and an impeller having an impeller shaft journaled by said hull, said transmission comprising an intermediate shaft adapted to be positioned between said crankshaft and said impeller shaft, a pair of coupling joints angularly movably connected to both ends of said intermediate shaft and adapted to be connected to said crankshaft and to said impeller shaft, bearing means connected to said intermediate shaft between the ends thereof, and resilient means connected to said bearing means and adapted to be mounted on said hull for elastically journaling said intermediate shaft on said hull for all directions of angular movement, and further including adjustment means attached to said resilient means and adapted to be attached to said hull for adjusting the position of said resilient means relative to said hull.
Claim 2
Dependent Claim
148 words
A transmission for a small boat including a hull, an engine mounted on said hull, said engine having a crankshaft, and an impeller having an impeller shaft journaled by said hull, said transmission comprising an intermediate shaft adapted to be positioned between said crankshaft and said impeller shaft, a pair of coupling joints angularly movably connected to both ends of said intermediate shaft and adapted to be connected to said crankshaft and to said impeller shaft, bearing means connected to said intermediate shaft between the ends thereof, and resilient means connected to said bearing means and adapted to be mounted on said hull for elastically journaling said intermediate shaft on said hull for all directions of angular movement, and further including adjustment means attached to said resilient means and adapted to be attached to said hull for adjusting the position of said resilient means relative to said hull.
Claim 3
Dependent Claim
135 words
In a small boat including a hull, an engine mounted on said hull, said engine having a crankshaft, and an impeller having an impeller shaft journaled by said hull, the improvement of a transmission comprising an intermediate shaft positioned between said crankshaft and said impeller shaft, a pair of coupling joints angularly movably connected to both ends of said intermediate shaft and connected to said crankshaft and to said impeller shaft, bearing means connected to said intermediate shaft between the ends thereof, and resilient means connected to said bearing means and mounted on said hull for elastically journaling said intermediate shaft on said hull for all directions of angular movement, and further including adjustment means attached to said resilient means and to said hull for adjusting the position of said resilient means on said hull.
Claim 4
Dependent Claim
135 words
In a small boat including a hull, an engine mounted on said hull, said engine having a crankshaft, and an impeller having an impeller shaft journaled by said hull, the improvement of a transmission comprising an intermediate shaft positioned between said crankshaft and said impeller shaft, a pair of coupling joints angularly movably connected to both ends of said intermediate shaft and connected to said crankshaft and to said impeller shaft, bearing means connected to said intermediate shaft between the ends thereof, and resilient means connected to said bearing means and mounted on said hull for elastically journaling said intermediate shaft on said hull for all directions of angular movement, and further including adjustment means attached to said resilient means and to said hull for adjusting the position of said resilient means on said hull.
