' '."lineiA-B of the preceding figure.

Be it'known that I, ARMAND Dnrnnnnssm,

a citizen ofthe French Republic, and 'resident ot Paris, France, have invented certain newand useful Improvements -in and Re lat-ing to )Optical Toys,of which the fol-'ny such-as illustrated post cards'and the like on relates to improve` a White screen isbased upon the Well known principle of reflecting surfaces' and com.-

prises' substantially a box l'having a rectangular shape, closed on all sides and the front and rear Wallsl of which are respectively provided with an opening 2 and an I so " tangular or vided. at its front end with objectlve 3.

e are incandescent lamps representing the source of light.-

The objective comprises a sleeve 5 adapted to frictionallyslid'e in the bent borders G of the front Wall of the box. The sleeve is proa 'narrow rim 7 against Which bears the lens 8'. The latter is held in place by a second sleeve 9 having-a blackened inside and adapted to be forced into the said sleeve 5. The opening -2 before which the illustrated post cards or opaque images of any kind appear is covered by a plate 10 having a rec uadrilateral shape and vWhich issecured tot e back'of the box by means of a hinged stirrup 11,.' As readily seen, this stirrup 11 is held by means of hinges 12 and is-provided at the free ends of its branches With pivots 13 adapted toengage step bearings la'secured by soldering to the middle I v part of the upper and lower borders of .the 'supporting platelO. This plate 'isprovided at its upper and lower borders and on both sides With' guide-Ways 15. It carries besides on both lsides four`hooks 16 made of sheet metal and the vertical distance of which corresponds l to the .Width of an illustrated post Acard 17. In order'to cause the plate 10ste surround exactly the edges of the opening 2 "that card side, of the' the guide-Ways 15 may be coveredW-ith a thin layer. of felt or of fabric. A l

The function and the manipulation of this toy are as follows: The illustrated post# cards 17 .or other vopaque objects 4are slid between the hooks or between the guidefways 15 according to Whether the image or post` card is to be read in the direction of the height or' inthe direction of the Width.'

While the post card secured toone side of the card carrier l0 is lighted or rejected, which ison the other side is With` drawn and replaced by another one. .The supporting plate 10 is afterward removed from the opening 2 by causing it to revolve through -an angle of 180 and is then again applied against' the opening 2 so that the card inserted last is now opposite the 0bjective.

It Will be readily understood that the incandescent lamps might vbe replaced as Well by another equivalentsouree of light such as a gas burner, a petroleum lamp or the like.

18 are air holes arranged4 in the bottom of the box andadapted to admit fresh-air to the inside of the latter.

Having now fully described my said invention, what I claim and desire to secure by Letters'Patcnt is 1.
