ABSTRACT:
A slide mount comprising a main frame and a separate fitting frame which is easily separable from the main frame to quickly mount a transparency or demount it for changing to another one. The main frame has a concavity for receiving a transparency and the fitting frame adapted to be removably inserted into the concavity to fit the transparency against the main frame. In the center of its concavity, the main frame has an opening which is substantially of the same size as the picture on the transparency and is so positioned as to become aligned with the picture upon insertion of the transparency into the concavity. Likewise, the fitting frame has in its center an opening which is substantially of the same size as the opening in the main frame and alignable therewith upon insertion of the fitting frame into the concavity of the main frame. The concavity in the main frame is substantially of the same size as a transparency, so that when the transparency is placed in the concavity and the fitting frame is applied against the transparency, the picture becomes correctly aligned with the openings in the main and fitting frames for accurate projection through those openings.
