Field of the Invention Viewing of prints, pictures or snap shots successively from a stack thereof and re-stacking them in the same order they had been initially stacked.

2. Description of the prior art Applicants US. Pat. No. 3,495,345 is deemed to be an example of the prior art as it relates to feeding pictures successively from a stack that is located in viewing position and effects successive transfer of pictures from the top of the stack to the bottom thereof by means of a shuttle, the operation, thereby, having a closed cycle making it more time-consuming to add to or remove pictures from the stack thereof, or exchange one or more of said pictures for others.

SUMMARY OF THE INVENTION Rendering efficient the handling and feeding of pictures from the bottom of a stack, one at a time, to a viewing position beneath a magnifier lens, while simultaneously feeding pictures from viewing position to a pile thereof in which the pictures are in the same arrangement that they were when in stack arrangement, providing a single shuttle to carry out said simultaneous picture feed, and further providing a tray for collecting said picture pile and mounting said tray to be slidable from a non-operative retracted position to an operative extended position to receive the pictures of said pile.

An object of the invention is to provide a picture viewer embodying the above outlined characteristics, as well as providing for utilizing the picture-flattening component of the device with means for storing additional pictures.

Another object of the invention is to provide a picture viewer, as above characterized, that is of such simplified form and construction that complicated and expensive means for insuring proper feed of pictures are unnecessary, thereby materially reducing manufacturing cost and yet greatly improving the accuracy of picture feed.

This invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description which is based on the accompanying drawing. However, said drawings merely show, and the following specification merely describes the preferred embodiments of the present invention, which are given by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top plan view ofa picture viewer according to the present invention, the same being shown in operative condition.

FIGS. 2 and 3 are end elevational views as seen, respectively, from the left and right ends of the viewer.

FIG. 4 is an enlarged sectional view as taken on the line 44 of FIG. 2 with the view in closed nonoperable condition.

FIG. 5 is a view similar to FIG. 4, partly in elevation and shown in open, operable condition preparatory to simultaneously feeding a picture from stacked to viewing position and a picture in viewing position to a restacked pile.

FIG. 6 is a broken sectional view as taken on the plane of line 66 of FIG. 5.

FIG. 7 is a partly broken plan view of a picturefeeding shuttle used in the viewer.

FIG. 8 is a fragmentary sectional view of means for placing an additional picture-flattening bias on the component disposed upon the stack.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The picture viewer that is illustrated comprises, generally, a main housing 10, a shuttle 11 for feeding pictures 12 disposed in a stack S adjacent one end of said housing to a viewing position adjacent the opposite end, a member 13 disposed upon said stack to flatten the same to have edgewise engagement with the shuttle for feeding movement of the picture at the bottom of the stack, a tray 14 at the picture-receiving end of the main housing movable between a closed non-operative condition, as in FIG. 4 and an extended, operative condition, as in FIGS. 1 and 5, to receive and form a pile S of pictures displaced by pictures that had been moved to viewing position by the shuttle. The shuttle, thereby, performs the dual function of simultaneously feeding a picture to viewing position and a picture from viewing position to restacking position. Means is provided to illuminate the pictures that are in viewing position.

The main housing 10 is preferably integrally formed to have a base 18 that is open at the end thereof that houses the tray 14. The bottoms of the base 18 and of the tray 14 are coplanar to provide a support for the housing and enabling ready extension of the tray from the closed, non-operative position of FIG. 4 to the operative position of FIG. 5. To limit the extension of the tray, in the operative position, the same is provided with a stop 19 that engages a projection 20 on the end of a member 21 affixed to the bottom of the base 18 to effect suitable location of the extended tray forwardly and relative to the housing base 18. As shown at 22, a longitudinal rib is provided in the interior of the tray to prevent the piled or re-stacked pictures from assuming a flat position on the tray bottom, the same rendering it easier to remove the picture pile S before sliding the tray back to the contracted position of FIG. 4.

Extending upwardly from the base 18 is a pair of guide walls 23 that locate the member 13 between them so the same has freely slideable movement, either by its own weight, by the added weight of a quantity of additional pictures 24 housed in a pocket 25 formed in said member, and/or by the additional bias of means 26 (FIG. 8), whether by spring or by additional weight. This weighted member 13 has the purpose of placing a flattening bias upon the pictures of the stack S and yet enabling the same to be fed, consecutively, to viewing position by the shuttle 11.

It will be noted that the top wall 27 of the base 18 (see FIG. 2) is disposed at an angle to the base of the viewer so the stack S disposed thereabove has a similar angular disposition as do the upper portions of the body 10 and the member 13. Accordingly, insofar as the wall 27 is concerned, the same constitutes the base plane for all portions of the viewer except the base 18.

The member 13 is provided with a flat bottom plate 28 for engaging the top of the stack S, and with a handle 29 at its top by which removal and replacement of said member is facilitated.

It will be noted that a wall 30 encloses the rear edge of the stack of pictures S, one or more ribs 31 being provided to engage the rearward edge of the bottom plate 28 of member 13 to retain the member 13 in operative position.

Forward of the space occupied by the stackweighting member 13, the body 10 is provided with an upwardly extending hollow portion 32, at the upper end of which is provided an enlarging lens 33 through which the interior space of said portion may be viewed. The above-mentioned wall 27 extends forwardly along the bottom of said interior space, the lower edge 34 of portion 32 being spaced from the sloping top wall 27 of the base 18 to form a slideway 35 for the shuttle 11.

The means 15 for illuminating the interior of the housing portion 32 may be detachable and be slid from its guides 36 on the portion 32 for access to a lamp 37 in said means for replacement thereof as required.

The shuttle 11 is disposed to slide upon the top face of the wall 27, being guided in the slideway 35. Said shuttle is provided with a forward portion 38 with a forward edge 39 for displacing pictures from their viewing position, and a rearwardly positioned shallow rib 40 for displacing the bottom picture of the stack S. It will be noted from FIG. 7 that the space between the shuttle edge 39 and the rib 40 and the width of the pictures 12 are substantially equal.

Said shuttle is provided with an extension 41 that passes through an opening 42 in the wall 30, a manipulating handle 43 being provided on the outer end of extension 41.

It will be understood that the pictures 12 are of the type that are approximately 0.010 inch thick. In order that the rib 40 shall engage only the rear edge of the bottom picture of the stack, the latters height should be less than the pictures thickness, for instance 0.0008 inch, so said rib will not engage the picture in the stack next above. Also the space between the edge 32 and the shuttle portion 38 shall be such as to allow free passage of a picture 12 but intercept the picture of the stack next above. Such space, if one and one-half times the thickness ofa picture, will insure proper single picture feed as the shuttle is actuated.

The foregoing should be considered as exemplary inasmuch as back-provided pictures or other thicker than the 0.0l inch thickness above mentioned may be handles in viewers proportioned accordingly.

Rearward of the rib 40 of the shuttle 11, adjacent the front and back edges thereof, are provided tab means 44 that are rearward extensions of the shuttle portion 38. When the shuttle is retracted preparatory to moving the bottom picture of the stack S to viewing position, these tabs extend from openings 45 of the wall 30. When the shuttle is shifted to the position of FIG. 4, said tabs 44 will remain beneath the forward portion of the stack to prevent the same from dropping behind the pickup rib 40. These tabs thereby prevent jamming of the shuttle feed as well as facilitating loading the viewer with pictures.

While the foregoing has illustrated and described what are now contemplated to be the best modes of carrying out the invention, the constructions are, of course, subject to modification without departing from the spirit and scope of the invention.
