Abstract
A picture viewer having a housing to confine a pile of pictures, a slider to be withdrawn and returned to the housing, a viewing window, a pressure plate confronting the window, springs urging the plate toward the window, a retention strip to engage and strip off the picture at the end of the pile upon withdrawal of the slides, a separator strip to retain the pile as the one picture is stripped off, a slidable button on the housing to disable the springs and draw the plate away from the window, and a confining ledge on the slider also drawing the plate away from the window and independently of the slidable button.
Claims23
A picture viewer for a pile of pictures, comprising
- enclosure means including a frame defining a viewing window and a slider reciprocably mounted on the frame, the frame and slider having relative obverse and reverse sliding movements in opposite directions along the window, the enclosure means also defining a picture compartment having one end adjacent the window to contain a pile of pictures with a picture at one end disposed at said one end of the compartment and adjacent the window,
- a picture changing mechanism adjacent the picture compartment for removing an individual picture from one end of the pile and returning the individual picture to the other end of the pile in response to said relative obverse and reverse sliding movements of the frame and slider to present a new picture at the window for display,
- said picture changing mechanism including a pile transporter and an individual picture transporter, one of the transporters being connected with the frame and movable therewith and the other of the transporters being connected with the slider and movable therewith, the pile transporter being disposed at one side of the compartment to engage one side of the pile of pictures, the picture transporter being disposed at one end of the compartment to engage such an individual picture at the corresponding end of the pile of pictures, the transporters producing relative movement of the pile of pictures and of the individual picture during changing of the picture at the window, one of the transporters having controllable means operable between alternate functional and non-functional conditions to produce said relative movement when rendered functional, and
- a disabling means including a disabling control movably mounted on the enclosure means at the exterior thereof, said disabling control having connection with the controllable means of said one transporter for rendering said one transporter non-functional for producing the relative movement in response to movement of the disabling control at the exterior of the enclosure means.

Storing and viewing apparatus for a pile of pictures, comprising
- a shelving element having an open-ended housing compartment,
- a picture viewer in one of said compartments and being removable therefrom, the picture viewer having enclosure means including a frame defining a viewing window and a slider reciprocably mounted on the frame, the frame and slider having relative obverse and reverse sliding movements in opposite directions along the window, the enclosure means also defining a picture compartment having one end adjacent the window to contain a pile of pictures with a picture on one end of the pile disposed at said one end of the compartment and adjacent the window,
- a picture changing mechanism adjacent the picture compartment for removing an individual picture from one end of the pile and returning the individual picture to the other end of the pile in response to said relative obverse and reverse sliding movements of the frame and slider to present a new picture at the window for display,
- said picture changing mechanism including a pile transporter and an individual transporter, one of the transporters being connected with the frame and movable therewith and the other of the transporters being connected with the slider and movable therewith, the pile transporter being disposed at one side of the compartment to engage one side of the pile of pictures, the individual picture transporter being disposed at one end of the compartment to engage such an individual picture at the corresponding end of the pile of pictures, and the individual picture transporter including pressure means applying pressure on the pile of picutures toward one end of the compartment, the transporters producing relative movement of the pile of pictures and of the individual picture during changing of the picture at the window,
- disabling means including a disabling control movably mounted on the enclosure means at the exterior thereof, said disabling control having connection with the pressure means for relieving the application of pressure against the pictures and rendering said individual picture transporter inoperative in response to movement of the disabling control at the exterior of the enclosure means, and said shelving element having operating means engaging and moving the disabling control relative to the enclosure means during insertion of the picture viewer into the housing compartment for disabling the picture-changing mechanism and relieving pressure from the pictures upon insertion of the viewer into the compartment of the shelving element.
