Abstract
An apparatus for defining arcs of mixed radii on a workpiece includes a base, a first selectively extensible arm rotatably mounted to the base, and a second selectively extensible arm rotatably mounted to the first arm. An assembly for defining the arm on the workpiece is mounted to the second arm. An assembly is provided for releasably retaining the first arm at a first disposition for selective movement of the arc defining assembly through a first predetermined angular displacement to define a first arc with a first predetermined radius and to retain the second arm at a second predetermined position for selective movement of the arc defining assembly through a second predetermined angular displacement to define a second arc having a second predetermined radius.
Claims14
An apparatus for defining arcs of mixed radii on a workpiece comprising:
- a base member;
- a first selectively extensible arm movably mounted to said base member;
- a second selectively extensible arm movably mounted to said first arm;
- means for defining an arc on a workpiece mounted to said second arm;
- means for releasably retaining said first arm at a first disposition for selective movement of said arc defining means through a first predetermined angular displacement to define a first arc having a first predetermined radius;
- means for releasably retaining said second arm at a second predetermined disposition for selective movement of said arc defining means through a second predetermined angular displacement to define a second arc having a second predetermined radius.
