Stéréo-Classeur Leroy

Region: France    Period: 1890–1930    Tag: Leroy Stereoscope type: Tabletop » Multi-view » Tray-based

The stereoscope carries the name Leroy, although the namesake played no role in its development. The manufacturer of the stereoscope, Émile Guérin, continued the company of Lucien Leroy and retained the established name Leroy as a brand.

The Stéréo-Classeur Leroy is a compact stereoscope with a distinctive mechanism. The glass slides are lifted by being clamped between two grips positioned at the sides of the device. In most tray-based stereoscopes this movement is produced by two metal fingers that rise from the bottom of the housing. Such a mechanism requires additional space beneath the body of the viewer. The Stéréo-Classeur Leroy avoids this requirement through its side-mounted arms, which contributes to the compact dimensions of the stereoscope.

A quote from La Nature no. 2593:

…immediately highlights one of the most interesting characteristics of this device, namely the small volume, the entire mechanism, extremely compact and robust, is arranged laterally and the slides, instead of being raised by a metal finger which lift them by their lower edge, are grasped by the sides by means of pliers which raise them to the height of the eyepieces, just as one would do with the fingers. We have thus eliminated all the space which is usually necessary to allow the metal finger to disappear when the plate descends into its groove, and produced a device which, for the 6 x 13 format, does not exceed 0.20 m. in any of its dimensions.
