ABSTRACT:
An apparatus is provided for retaining parallels against vise jaws during the entire cycle of performing a machining operation. The subject method and apparatus apply sufficient forces at the places and angles necessary to avoid any flutter or movement of the parallels outwardly away from or transversely across the faces of their respective jaws. By use of the subject invention, the parallels are retained against the jaws of the vise over a range of jaw gaps from a very narrow gap to the maximum jaw gap of vises typically used in machine shops. Also, undesirable movement of the retaining apparatus relative to the vise and parallels is restricted. The apparatus has a low profile and is located in the space under the machining area so that it does not interfere with the machining operations, but if contacted by the machine tool, will be sacrificed rather than the more expensive tool.
