Abstract
The lockout device is intended for use on safety switches for controlling electric power equipment. It comprises a cable with a tip connected at one end. The tip is adapted to be threaded through holes on the actuators of safety switches. The tip has one or more openings for receiving padlocks to prevent removal of the cable from the switch actuators. The other end of the cable is constructed so that it is unable to pass through the actuator holes. This may comprise an enlargement at the end of the cable or the cable may be attached to the housing of the power equipment.

A power lockout device for a control center comprising a plurality of power source switch boxes each having a safety switch whose switch handle has a hole alignable with a matching hole on the switch box when the switch handle is in an off position comprising:
- (A) a cable;
- (B) a tip connected to one end of said cable adapted to be threaded through aligned holes of a sequence of safety switches in the power off position;
- (C) said tip having a transverse opening adapted to receive a padlock;
- and
- (D) passage prevention means adjacent the other end of said cable adapted to prevent that end of said cable from passing through a switch handle hole;
- (E) whereby said tip and connected cable can be threaded through a sequence of safety switch handles in the off position and a padlock is mounted in said transverse opening of said tip and locked so that each threaded safety switch cannot be switched from the off position.
A power lockout device for a control center comprising a plurality of power source switch boxes each having a safety switch whose switch handle has a hole alignable with a matching hole on the switch box when the switch handle is in an off position comprising:
- (A) a cable;
- (B) a tip connected to one end of said cable adapted to be threaded through aligned holes of a sequence of safety switches in the power off position;
- (C) said tip having a transverse opening adapted to receive a padlock;
- (D) whereby said tip and connected cable can be threaded through a sequence of safety switch handles in the off position and a padlock is mounted in said transverse opening of said tip and locked so that each threaded safety switch cannot be switched from the off position.
A power lockout device for a motor control center comprising a plurality of power source switch boxes each having a safety switch whose switch handle has a hole alignable with a matching hole on the switch box when the switch handle is in an off position comprising:
- (A) a plastic coated cable;
- (B) a needle-shaped steel tip connected to one end of said plastic coated cable adapted to be threaded through aligned holes of a sequence of safety switches in the power off position;
- (C) said needle-shaped steel tip having a transverse opening adapted to receive a padlock;
- and
- (D) coupling means connected to the other end of said plastic coated cable for coupling said cable to the motor control center;
- (E) whereby said needle-shaped steel tip and connected cable can be threaded through a sequence of safety switch handles in the off position and a padlock is mounted in said transverse opening of said tip and locked so that each threaded safety switch cannot be switched from the off position.
