ABSTRACT:
An improved positioning jig which includes two principal relatively flat members adapted for locking and unlocking engagement/disengagement with each other and which are normally urged apart in the unlocked condition by a pair of elongated spring-like members which separate the two principal relatively flat members. Each of the two members includes a mating set of teeth which are adapted for engagement with corresponding teeth on the other member and which permit adjustments in small discrete steps over an extended range. When it is desired to lock the two members together, a bi-directional cam clamp is rotated through about 90 degrees so as to impart a vertical camming force to the upper relatively flat member thereby forcing it downwardly in opposition to the spring bias until teeth of the upper member and those of the lower member are engaged thereby locking the members together in the desired relationship. Also included are improved scalar measuring devices which are adapted for coordination with the aforementioned principal flat members so that in combination they together provide enhanced operational characteristics.
