Title: Verle L Doty: Innovator in Load-Unload Devices
Introduction
Verle L Doty is a notable inventor based in Harrison, OH (US), recognized for his contributions to the field of load-unload devices. He holds two patents that showcase his innovative approach to solving problems in vertical conveyor systems. His work has significantly impacted the efficiency and safety of material handling processes.
Latest Patents
Doty's latest patents include a load-unload device with a limit overload sensing feature. This device is designed for use in vertical conveyor systems and includes mechanisms for sensing jam conditions between a downward-moving conveyor tray and articles that fail to unload. The invention features a linkage system that creates an over-center locked condition, which is automatically releasable at a preset force. A spring absorbs the load from a jam, generating the necessary force to unlock the linkage and allow the platform to relieve the overload. Additionally, a limit switch is integrated to open the conveyor drive motor's down circuit as the platform moves.
Another significant patent by Doty is a load transfer mechanism with jam-preventing controls for vertical shelves. This conveyor system features horizontal shelves that travel vertically within a casing, equipped with transfer means at load transfer stations. A safety cable is positioned to deflect misplaced articles, actuating a switch that turns off the driving electric motor to prevent jamming. The transfer mechanism includes interdigitate transfer fingers that work in conjunction with shelf fingers to facilitate the transfer of articles. Control means are in place to sense the position of the transfer fingers, ensuring safe operation of the conveyor.
