Latest Patents

Bartholomew's latest patents include a "Combined arc shield/wire tray for switchgear and switchgear assemblies incorporating same." This invention features a switchgear assembly where multiple cells housing electrical switching apparatus, such as circuit breakers, are vertically stacked. The design incorporates combined arc shield/wire trays that facilitate easy access to secondary wiring through the front doors of the assembly while protecting the wiring from circuit breaker arc gases. The arc gases are effectively deflected by an inclined panel that forms the back wall of the wire tray. Additionally, a vertical wall mounts terminal blocks and a wireway that communicates with the wire trays, ensuring efficient wiring management.

Another significant patent is the "Switchgear assembly with integral control wiring wireway." Similar to his previous invention, this assembly also features vertically stacked cells and combined arc shield/wire trays. The design ensures that external wiring can enter the wireway through designated access openings, while a depending lip on the rear of the arc shield diverts arc gases into a vertical chamber for cooling and expansion.
