ABSTRACT:
An automatic cover slipper for microscope slides has a base with guide means to mount a manually reciprocating slide having an advance position and a retracted position. The base has a pair of transverse apertures to receive a microscope slide and a stack of slide covers, respectively. A slide cover lifter assembly is mounted on the slide and includes a depending suction cup for manually gripping and lifting a slide cover when the slide is in advance position. A cement dispenser assembly with a reservoir is mounted on the slide and has a control valve for automatically dispensing a measured amount of cement onto the microscope slide when the reciprocating slide is in advance position. The lifter assembly on movement to retracted position is adapted to transfer the cover into registry with the microscope slide and for dropping the cover thereon in juxtaposition.
