ABSTRACT:
A combination amalgam condenser and carrier apparatus employs a base assembly which accommodates a rod. The rod is employed in both a carrier and a condenser position and is located within a plunger member and retained therein by means of a securing member which is positioned between two prongs formed at the end of a lever member. The lever member is pivotally mounted with respect to the handle and by moving the lever, one can operate the apparatus in a condenser position where the rod protrudes from the plunger and in a carrier position where the rod is located within the plunger. The lever member has a clip mechanism which coacts with a latch mechanism located on a carrier base assembly; which base assembly is integrally formed with the rod. The clip mechanism as coacting with the latch provides a locking action defining a condenser position when the lever is pivoted towards the handle. When the locking mechanism is released, the apparatus is operative in a carrier position as defined by the rod located within the plunger.
