Abstract

225,805. Montigny, A. Dec. 6, 1923, [Convention date]. Printing - apparatus with bordering masks.-A frame for holding a sensitive sheet in reproducing by projection is adjustably mounted relatively to the optical axis or light source by means of bolts (not shown) extending through slots in supporting arms 2. The frame comprises a three sided easing 5 on abase plate 1 and a hinged cover 6 having an aperture or window 8 overlapping which is detachably mounted an interchangeable border frame 11. A plate 15 the same size as the window aperture 8 is supported by a resilient spring blade 16 secured to the cover, and when the frame is closed just fits within the window 8. The cover is normally held open by a spring 12. Metal strips 9 terminating in flanges 10 extend from the sides of the window 8, and serve as lateral guides for a sheet of sensitive paper which is placed on the plate 15. Another spring 13 fixed to the base 1 carries a block 14 which, when the cover 6 is closed and held by hooks 17, presses the plate 15 and sensitive paper against the border frame 11.
