Abstract

The slides are fed into a shoot 8, 9, 10, pressing back a spring bar 12, until free to be moved forward into contact with the last slide inserted, which is being exhibited by the light passing through the apertures 3. The slide which has just been displayed is pressed against a cushioned stop 7 ; when this slide is withdrawn, the spring bar 12 is thrown forwards by the spring 5, or by the finger pressing on the extension 15, and the new slide is brought before the condenser ; another can then be inserted, and so on for the whole series.
