Abstract
1,081,726. Transparency storage and display apparatus. J.S. WRIGHT. March 29, 1966, No. 13738/66. Headings G2A, G2C and G2J. A pack 40 of transparencies are bound by ring binder 47 to covers 36, 37 hinged together at 38, the free edge of cover 36 being received in a spring clamp on a frame 45 resting on glass table 50 of an overhead projector. Cover-plate 52 rests on each transparency as it is pivoted about rings 47 to the viewing position as at 53. After viewing, cover 37 is raised and transparency 53 is swung between covers 36, 37 and the next is pivoted on to frame 45. Transparencies may be projected in superposition. In another form, the frame may be formed as a hinged extension of cover 36.
