.lBi fern slide mi with openings 28 adapted, in the assembled condition of parts, to register with the openings 34 in the frame. In the assembled condition of the parts, it is contemplated that the lass plate 26 with its mats 27 will be fixe ly secured in the frame 33.
The invention provides also a transparent plate 29 formed on one side with two film representations designed in the assembled condition of parts to register with the openings 28 and 34. The two representations? are, in practice, different pictorial views, and the film surface is coated with some protective medium such as varnish. There will be provided for theuser a variety of plates 29 with a variety of representations on them, and the user aving selected the desired plate 29 from his supply, places it in the In FigL'3 it will be noted that the second tube 18 is not included within the tube 13. Furthermore, in this-figure the carrier 21 with the smaller slide is omitted, and in its place is shown a" carrier 22 in the holder formed by the opening 11, and the carrier holds in place a larger or standard slide formed by placing in the carrier a cover glass 23 and a glass 24 which bears the representation whose image it is desired to project.
In operation, if the user of the lantern has on hand the standard slide and desires to project its image, he will leave out the tube 18 with its objective 19 and will use merely the tube 13 with its objective 14 and he will place the standard slide in position in the holder formed by the opening 11.
The objective is designed to project the frame 33 with the film side facing inwardly image from the standard slide, the proper against the cover lass secured in the frame focus being gained by longitudinal y adand then places the assembled parts in the carrier 21 which is then inserted in the holder formed either by the pins 12, or otherwise.
It will be noted justing the tube 13 in the outer portion 9 of the conduit. If the user, however, desires to provide himself with the smaller slides 25 at a very considerable saving compared with v the cost of the larger or standard slide, he there is providedti-comparatively small plate may quickly adapt the lantern for use with formed with two pictures or other reprethe smaller slide. He first removes the tube sentations, and that these may be more or 13 from the conduit (portion 9 and inserts less freely handled because the film surface 3 in the tube the secon tube 18 with its 010- is covered with a rotective medium. The jective 19, the objectives 14 and 19 both beframe has within'it a cover glass, and this ing plano-convex with their convex surfaces frame receives any of the smaller plates facingtoward each other. The tube 13, carwhich the user desires to use so that only Tying the tube 18 is then longitudinally adone cover glass is needed and with 1t can be 35 justed in the conduit portion 9 and the used any one of a great number of the smaller slide having been inserted in the smaller plates 29.
