| 139 | Electrical safety lockout mechanism for power tools and other hazardous machinery | US11456320 | 2006-07-10 | US07391134B2 | 2008-06-24 | Thomas E. Feil |
| An improved electrical lockout mechanism includes a first connection means to a power source, and a second connection means to the power input terminal of the machine being protected. The machine being protected includes a manually-operated ON/OFF switch. A switching element is operably coupled between the first and second connection means. The switching element is adapted to selectively complete and break an electrical circuit between the first and second connection means in response to a control signal supplied thereto. A control circuit generates a control signal that is supplied to the switching element thereby causing the switching element to complete the electrical circuit between the first and second connection means under a first set of operating conditions and causing the switching element to break the electrical circuit between the first and second connection means under a second set of operating conditions in a manner that prevents unwanted machine restarts. The switching element may be realized by an electromagnetic relay device, or by a thyristor-based switching device such as a triac device. The electrical lockout mechanism can be integrated with a power cord that delivers electrical power to a machine, or can be integrated into the machine itself. | ||||||
