Abstract
The object table is pivotted on a bracket under the glass viewing position, with the bracket suspended by a vertical arm in a slot fitting on the equipment. A hand lever is pivoted in friction coupling and engages the vertical arm by another slot coupling to provide a simple, compact mechanism for raising the original. The friction coupling is fitted with an adjusting screw to take up wear.
