The Optical Magic Lantern Journal (August 1893)

The Optical Magic Lantern Journal and Photographic Enlarger. 111 For sake of convenience, the greater part of Fig. 4 can be made of zinc, to which can be attached two pieces of talc, painted out to the ig. 4. requisite size and shape with opaque varnish. A hole is pierced in the zine as at A. The necessary parts of the slide having been sketched and painted, the next thing is to secure them on the frame in their respective places, and to ascertain that they fit accurately. The glass containing Cupid having been fastened in its place, the glass, Fig. 2, should be fastened by a screw at B. Next the arrow may be adjusted by a screw in like manner at C, and then the wings, Fig. 4, at AA. Excepting the fastening of a glass at the back containing the eyes, the slide is ready for placing the stops in positior. The eyes will roll or move from side to side by slightly moving the glass on which they are painted. Raising or lowering the lever of Tig. 4 will give the appearance of the wings fluttering. Next the lever of Fig. 3 can be depressed, which will bring the end of the arrow close to the forefinger of the figure. By slowly pushing down the lever of Fig. 2, the effect of drawing the bow will be given ; and if everything be made in the exact proportion given in the sketches, the bowline will be represented by the edge of the slass, Fig. 3, which, to brighten the effect, may have the edge blackened. Having put the slide together, the reason for the white patch on Fig. 1 and the black patch on Fig. 2 will be apparent, for unless the white patch were left, the end of the bow would not be seen. By raising the end of the lever, Fig. 3, the arrow will appear to be shot from the bow, whilst the manipulation of the lever, Fig. 2, brings the bow back to it original position again. A fine effect can be produced with a double lantern by flashing on (soon after the arrow has | left the bow) a picture of a heart with an arrow sticking in it; or, better still, without the arrow, which, on the slipping-slide principle, can easily be made to appear as in the act of striking its target. We have at the present time in our possession the walking skeleton slide, which was used at the Polytechnic with the Phantasmagora lantern, at which time it created such a wierd effect. This slide we shall describe, with drawings, In our next issue. Hand-Cameras for obtaining Slides for the Lantern. “Facile” -March Ist,"90 No.15 “Repeater” .. Aug. 1st,’91 No. 1‘‘ Giah” -.

It appears that this particular camera is now upon the English market, having been just imported by the European Blair Camera Co. (Limited), of 9, Southampton . Street, W.C. This camera is neat, well made, | and takes pictures of 34 inches square or of circular shape, and can be loaded with a film cartridge in daylight, no dark rdéom being required. Supposing the camera to be empty, it is loaded as follows :—By undoing a screw at the bottoin, the exterior covering can be drawntoff. Film Cartridge. A prepared cartridge film is then dropped into place, and secured by a spindle passing through the wooden reel; the end of the black paper, which will be found on the cartridge, is then drawn over the focal plane, and its end slipped through a slot in another reel upon wheeh it is wound, the handle of this being on the outside of camera. The black paper having been placed in position, the outer casing of the camera is now put on, when immediately at the back of it will be seen a small hole covered with ruby glass. The black paper is then wound on the latter reel until the figure 1 appears at the aperture, which indicates that sufficient film (which is. rolled. up. with the black paper after the fashion of ribbons in drapers’ shops) has been
