ABSTRACT:
A device for smearing liquid on a slide has (1) a housing and means for supporting a pair of slides on top of the housing, (2) a carriage with a pair of spaced runners which slidably support the carriage on the top of the housing, (3) a spreader pivotally mounted on the carriage and free to rock transversely with respect to a slide, (4) a member to advance the carriage and spreader, (5) a spring and dashpot arrangement to retract the carriage, and (6) latch means to arrest the carriage after it retracts a short distance. The means for supporting the slides may support the slide at an angle of at least five degrees with respect to the plane in which the carriage moves reducing the thickness of the liquid smeared on the slide. The dashpot plunger moves in the direction of an open end of the dashpot cylinder. Advantageously the device has means to clean the spreader.
