Abstract

266,869. Berry, H. H. Oct. 19, 1926. Stereoscopes.-Portable stereoscopes having a folding lens-carrying front member d connected by a base a to a folding picture-carrying member x constructed to take a number of cards connected to the base by two-piece loops or rings f. The back member x is provided with a pivoted back-rest adapted to stand in stop-hinge manner when opened. A stud fastener d is fitted to enable the stereoscope to be secured when closed. The edges of the cards may be stepped in index fashion.
