  • Shaft shielding top loader
    Patent number: 5114368
    Abstract: A shaft shielding top loader (20) for use in the inlet water channel (12) of a water craft (10) is disclosed. Shaft shielding top loader (20) is configured to divide the incoming water into an upper portion and a lower portion, where the upper portion supplies the top of impeller (13). This is accomplished using an arcuate top loading plate (21) supported by a shaft shielding partition (22). Shaft shielding partition (22) is configured to have a trailing straight edge which is colinearly juxtapositioned with respect to impeller drive shaft (14) to shield impeller drive shaft (14) from the force of the incoming water. Shaft shielding top loader (20) is attached entirely within inlet water channel (12) using a suitable attachment device, such as a screw, at grate connecting adapter plate (24) and shoe plate (26). Shaft shielding top loader (20) insures a continuous water supply to impeller (13) regardless of the craft's orientation to the flow of incoming water.
