ABSTRACT:
A holder for detachably mounting a glass electric lamp dome which includes a pair of dome holding arms mounted to a lever arm which in turn is pivotally mounted on a base plate. The lever arm and the dome holding arms are actuated by a finger engageable lever formed as part of one of the dome holding arms and having a finger engageable terminus at the end opposite the end attached to the pivot arm. A feature is spring biasing means connecting the base plate and the lever arm to continuously urge the dome holding arms outwardly in dome holding locking position unless the finger engageable dome holding arm is moved inwardly. Another feature is lock means associated with said finger engageable dome holding arm to premit the locking of said mechanism in a dome disengaging position so that the dome can be removed and replaced.
