PICTURE-CASE. 'y

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern.-

Be it known that I, GEORGE BROWNLEE, of Princeton, in the county ot' Gibson, and State of Indiana, have invented anew and improved Photoscope; and I do hereby declare that the following is a full, clear; and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 represents avertical longitudinal section of my improved photoscope.

Figure 2 is a plan or top view of the same.

Figure 3 is a side view of the saine.

This invention relates to a new apparatus for displaying, successively, any suitable number oi photographic or other-pictures.-

The object of this invention is to construct a case,

not lunch larger than necessary to hold the pictures, and without any'nlachinery, and still to allow all pictures to be displayed, in the required succession, by the motion of the case. A The invention consists in the use of a box, with glass top and bot-tom, and with a,iransverse partition, which not quite reaches to the 'top and bottom, and which divides the case into'two chambers,.that communicatc with each other at the iop and bot-tom. The cards in the chamber can now, by revolving the case, be shifted from one side to the other, in the required succession.

A, in the drawing, represents a quadrangulan box or case, made ot' sheet-metal or other suitable material, of suitable size. Its top and bottom plates a b are made of glass or other transparent substance.

Equidistant'from both ends, is, in the case, a transverse partition, which divides the hox into two coinpa-rtments, eand f, ot' equal size.

There is a space left'between the top plate and the upper edge of thepartition, and one between the bottonrplate and the lower eilge of the partition, each edge being about as widens 4the thickness of two cards or pictures.

There are lugs, g g, fixed upon .the bottom plate b, in the chamber f, and similar' lugs, h, on the under side of the plate a, in the chamber e, these lugs being as high as thet-hiekuess of one card or picture.

.A- suitable number Aof cards isv placed into the box-one .set into each chamber. When there are,

say, twenty-one cards in the chamber e, so that thev upper one is in line with the top edge of the partition, there will, to the same height, b e but twenty in the ohaniberj, as `one thickness l is occupied in the latter chamber by the lugs g. When, however, the box is turned around, the twenty-one iu e will rest on the lugs h, and the one nearest b will, therefore, project beyond the partition, while the twenty in f will be be-` low the edge of the partition, as they rest directly upon the plate il'. as to hold the end e up, when the card nearest b in e will slide into the chamber f, and display thereby the face of the card which it formerly covered. Now there are twenty-one cards in f, and but twenty iu e, and, it the box is put into the position shown-in fig. l-that is to say, with b down-the uppermost card i in f will project above the top edge ofthe partition, as the cards in j' rest on the lugs g. The cards in e, however, will he below the top edge oi the partit-ion, as shown. \Vhen, now, the box is turni-d, to elevate the end j, the card i will slide into e, and will thereby disclose the card formerly covered by it. The box is now turned again, to bring the plate b to the top, when the cards in e will aga-in be above the partition, so that one can be transferred to f. thek box, the cards will be successively moved and displayed.

Either one or both the plates a b may be held in place by clamps D D, which can be adjusted, by piu` ion and rack J, so as to bring the glass platos more or less nea-i'.togetl1er, to tit the box to a suitable number of cards. 1u that case, the partition must be made of two pieces, which inove.with the respective plates, to make the .partition higherl or lower, in accordance with the size ot' the box.

One plate, b, can be made ot metal or other nontransparent material, in which case the cards can only be seen through the plate a.l

Having thus described my invention, I claim as new and desire A to secure by Letters Patent- The combination of the clamping-device D J D with a picture-receptacle, A, constructed as described.
