Title: Bruce L Hubbard: Innovator in Cotton Harvesting Technology
Introduction
Bruce L Hubbard is a notable inventor based in Ankeny, Iowa, who has made significant contributions to the field of agricultural machinery, particularly in cotton harvesting technology. With a total of 4 patents to his name, Hubbard's innovations have improved the efficiency and safety of cotton harvesting operations.
Latest Patents
One of Hubbard's latest patents is a lubrication distribution system for cotton harvester row units. This system utilizes a single constant displacement pump to provide lubricant under pressure from an on-board grease reservoir. The lubricant is distributed through a two-position valve to selected distribution manifolds mounted on the cotton harvester. Each manifold connects to multiple conduits leading to lubrication points on the harvester, ensuring that critical components such as picker bar cam tracks and picker drum drive gears receive adequate lubrication. The design eliminates the need for individual metering valves or pumps, simplifying the lubrication process.
Another significant patent is the operator presence switch with service by-pass. This control system automatically terminates power input to the picking units of a cotton harvester when the operator leaves their seat. It employs a seat switch and a delay timer to deactivate the hydrostatic drive, returning it to a neutral position. This safety feature ensures that the harvester stops moving when the operator is not present, enhancing operational safety.
