ABSTRACT:
A device for separating a microscope slide into two separate sections has a arm mounted on a horizontal pivot carrying a downwardly extending glass cutter. A releasable member maintains the arm in an elevated position. A slider advances a microscope slide under the cutter releasing the releasable member to lower the cutter onto the microscope slide. A striker on the arm strikes one section of the cut slide to separate it from the other section as the cutter drops off the trailing edge of the slide. The slide then raises the arm for the restoration of the releasable means preferably by a cam attached to the arm. Advantageously, the releasable member is spring biased to its position to maintain the arm in an elevated position and is released by a cam attached to the slide. Advantageously, the slide is supported on a bed having an opening for the downward passage of the section of the slide struck by the striker with the opening having a edge underlying the cut made in the slide by the cutter. Advantageously, the slide is removable for cleaning purposes.
