Name/TitleTray-Stere­o­scope ‘Planox’, First Version

About this objectA wood­en tray con­tain­ing 20 glass slides can be insert­ed by flip­ping down the front of the view­er, then, by mov­ing a knob, locat­ed on the right side, up and down, one slide after anoth­er can be exam­ined. The slides are pulled up by mag­nets which con­nect to met­al strips attached to the glass slides. Below the knob, a brass arrow will point to the num­ber of the slide that’s in view and allows nav­i­ga­tion to a spe­cif­ic slide. For that, the knob has to be stopped at an inter­me­di­ate posi­tion, which unlocks the tray move­ment. This posi­tion is also required to exchange the tray.
The view­er has a detach­able base con­tain­ing two draw­ers with three trays each, mak­ing it pos­si­ble to store a total of 120 slides.

Sub­ject and Asso­ci­a­tion Descrip­tionThe ‘Planox Stéréo­scope Mag­né­tique’ was one of the most pop­u­lar French stereo view­ers and is notable for its inno­v­a­tive mag­net­ic mech­a­nism. The basic idea was devel­oped by Mod­este Noel, who reg­is­tered his patents in 1913 and 1914. Alexan­dre Plocq was like­ly the first to use Noel’s inven­tion for pro­duc­tion mod­els. The draw­ings of a third patent in 1920, again by Noel, show the sim­pli­fied mech­a­nism found in the view­ers that were actu­al­ly pro­duced. Lat­er ver­sions made use of bake­lite trays instead of wood­en trays.
