Abstract

A lockout member is slidable between two positions where one position allows an electrical switch or a circuit breaker to be activated and a second position prevents activation of the switch or circuit breaker. The lockout member includes a downward extending portion which, depending upon the position of the lockout, provides for the ability to activate or deactivate the switch or circuit breaker.

Claims

1. Lockout apparatus adapted to be used with one or more switchable electrical devices comprising

a planar member having one or more first portions depending from a common second portion,

said one or more first depending portions being configured and positioned to physically interfere with the switchability of at least one of said switchable devices.

2. Lockout apparatus adapted to be used with a plurality of switchable electrical devices comprising

a planar member having one or more first portions depending from a common second portion,

said one or more first depending portions being configured to physically interfere with the switchability of at least one of said switchable devices,

said one or more depending first portions being positionable to a first position to prevent switching of at least a first one of said switchable devices and to allow switching of at least a second one of said switchable devices, and said one or more depending first portions are positionable to a second position to allow switching of said at least a first one of said switchable devices and to prevent switching of said at least a second one of said switchable devices.

3. The lockout apparatus of claim 2 wherein said at least one depending portion comprises one depending portion

4. The lockout apparatus of claim 3 wherein said one depending portion includes a second portion depending therefrom.

5. The lockout apparatus of claim 2 wherein said lockout apparatus includes two depending portions with a space therebetween.

6. The lockout apparatus of claim 5 wherein at least one of said two depending portions includes a second portion depending therefrom.

7. The lockout apparatus of claim 2 wherein said one or more depending first portions are angled away from a plane of said common portion.

8. The lockout apparatus of claim 2 wherein said one or more depending first portions lie in a plane spaced from a plane of said common portion.

9. The lockout apparatus of claim 2 including means for slidingly positioning said lockout apparatus from said first position to said second position.

10. The lockout apparatus of claim 9 wherein said means for sliding said lockout apparatus comprises one or more slots in said common portion.

11. Lockout apparatus in combination with electrical circuit breakers comprising

a lockout member having a common planar portion and one or more planar depending portions,

one or more electrical circuit breakers, each having a moveable lever for activating and deactivating said one or more circuit breakers,

said lockout member being positionable between at least two positions relative to said one or more circuit breakers, whereby one of said two positions of said lockout member positions said one or more depending portions to interfere with movement of the lever of at least one of said circuit breakers and said second of said lockout positions allows movement of said lever of said at least one of said circuit breakers.

12. The lockout apparatus of claim 11 wherein at least one depending portion includes a second portion depending therefrom.

13. The lockout apparatus of claim 11 wherein said lockout apparatus includes two depending portions with a space therebetween.

14. The lockout apparatus of claim 13 wherein at least one of said two depending portions includes a second portion depending therefrom.

15. The lockout apparatus of claim 11 including means for slidingly positioning said lockout apparatus from said first position to said second position.

16. The lockout apparatus of claim 15 wherein said means for sliding said lockout apparatus comprises one or more slots in said common portion.
