Introduction

James C Murphy is an accomplished inventor based in Broadview Heights, OH (US). He holds a total of 4 patents that showcase his innovative contributions to the field of vacuum cleaner technology. His work emphasizes the importance of effective filtration and user-friendly design.

Latest Patents

One of his notable patents is for an electrostatic particle filtration system. This invention features a vacuum cleaner equipped with an on-board electrostatic filtration device designed to remove ultra-fine particles from the air stream. The device utilizes a finely woven conductive mesh made from two sets of electrically insulated conductive filaments, across which a low voltage electrical potential difference is applied. The polarity of this potential difference is periodically reversed to maintain filtering effectiveness, even as particulate matter accumulates on the mesh. Additionally, high permittivity material is incorporated between the filaments to enhance the electric fields created by the electrical potential difference.

Another significant patent by Murphy is for a vacuum cleaner with a suction indicator. This design includes an adjustable-height suction nozzle and a diaphragm switch that measures the differential air pressure of the operating vacuum cleaner. The voltage source terminals are self-energizing, activated by the rotation of a brush inside the nozzle. An indicator lamp illuminates or extinguishes based on the suction level established by the nozzle's height relative to the floor surface.
