The Optical Magic Lantern Journal (September 1900)

114 The Optical Magic Lantern Journal and Photographic Enlarger. The emptiness of the vessel upon the table is thus revealed. The lever x is then allowed to resume its original position. The rod is pushed up by means of the spring Pp, and the cover is replaced on the dish. The lever 7, the end of which presses against the end of the beam 11, is now pressed upwards. As the protruding end rises the other end naturally descends, and pushes with it the beam 11. The perpendicular rod y is thus forced upwards. Owing to the manner in which they are pivoted, the right arm x swivels round, raising the wand in the air, and the head is thrown back a trifle. But as the end of the lever 7 falls it slides off the incline on the plate 6, and presently the end 5 of the beam 11 is released and springs back underneath the lever to its original position. As the beam thus springs back the connecting rod y is pulled down suddenly, and the arm x falls also—the wand held in the conjuror’s hand thus apparently giving the cover on the table a smart rap. At the same time the conjuror’s head is thrown down a trifle as it naturally would be in the act of striking. The lever 7 when released is pulled back by the spring 8 and falls down over the top edge 5 into its original position between 5 and 10. The game performance is again gone through by simply pressing the lever 7 up again, and in this way the conjuror can be made to give the vessel as many taps with his wand as desired. In order that the reader may thoroughly understand the movements that have just been described, the three Figs. IV., V., and VI. have been given. They represent end views of the parts we have been dealing with. Fig. IV. shows the position of the lever 7 and inclined edge 5 of the beam 11 previous to their being actuated. When the lever is moved it slides up the inclined edge of the plate 6, pushing before it the edge of the beam with which it isin contact. Bearing in mind the fact that the beam moves horizontally whilst the lever moves up the incline, it is obvious that there must come a time when the end of the lever will be higher than the top edge of the beam. When that point arrives the beam will be released, and, by means of the spring connected with it, pulled back into its original position. Fig. V. shows this action. 5a indicates the position occupied by the beam just as it is released. 5 represents it in its first position. Then, when the lever 7 is released it is pulled back down the incline, and passing over the top of the beam (see Fig. VI.); drops down into its proper place as shown at 7a. If he has followed this description carefully with the help of the diagrams, the reader will experience no difficulty in understanding thoroughly the exact action of these important parts of the slide. But let us continue our description of the action of the slide. After the cover has been struck several times by the magic wand, the lever p is pulled down to the stop H and kept there. The celluloid strip ¢ is thus forced upwards and the rabbit raised above the edge of the vessel on the table. The lever nN is now pressed up to the rest R and the cover is thus removed, revealing the rabbit snugly nestling within the dish. After a few moments N is released, the cover is thereby replaced, and G is also allowed to spring back. The rabbit thus drops down again whilst under cover. N is then pressed up, and the vessel shown to be empty—the rabbit having mysteriously appeared to and disappeared from view. (To be continued.) NEW KODAKS AND FILM. Kodak, Limited, are continually adding to their styles of cameras, the latest being the Panoram Kodak and the folding 1-plate Pocket Kodak. The Panoram takes long narrow pictures 7 by 24 inches with a swivelled lens, thus embracing an angle of view of 112. The film is exposed by degrees through a narrow slit which traverses the film, and for this purpose the lens can be actuated to move at two different speeds. The camera is covered in black morocco, and has nickelled fittings. The No. 3 folding Pocket Kodak, of which we give an illustration, is practically the same as one of a smaller size noticed in our columns some time ago. This, however, takes pictures
