Film Holder for Photographic Developing
The amateur photographer who uses roll film and who does his developing by the tray method, will find this device a simple and reliable means for holding the film spool while removing the film, duplex paper, autographic carbon paper, gummed labels, etc. Once the spool is properly placed in the holder, there is little danger of its dropping. The holder takes various sizes of film spools. The side fingers are ³⁄₁₆ by ³⁄₄ by 23 in. long. A small peg is set in each finger, 1¹⁄₈ in. from the end, to engage the spool. The upper ends of the fingers are nailed to a tapered block of wood, ⁷⁄₈ by 3¹⁄₄ and 2¹⁄₂ in. wide, and 8 in. long. The holder can be conveniently fastened to a wall, door casing, or to the under side of a shelf in the dark room.—John Hoeck, Alameda, Calif.
