MULTI-SCALE MECHANISM
First Claim
1. A multi-scale mechanism comprising:
- a rotatable driving shaft;
a first scale mounted along the axis of said rotatable driving shaft, said scale including first and second sets of coarse scale divisions for indicating a coarse range of magnitude in two different systems of units as a function of the position of said first scale with respect to said rotatable driving shaft;
a second scale for indicating a fine scale range of magnitude in one of said systems of units;
a third scale for indicating a fine scale range of magnitude in the other of said systems of units;
said third scale operatively connected to said rotatable driving shaft; and
a gear assembly connected between said second scale and said third scale having a predetermined gear ratio such that said second scale is caused to move at a different rate than said third scale.

15. A method for adjusting a tool to a desired value in either of two different systems of units, said tool including a first scale having a first set of coarse scale divisions in one of the systems of units and a second set of coarse scale divisions in the other of the systems of units, for simultaneously providing a coarse range of magnitude in both of said systems of units, a second scale for indicating a fine scale range of magnitude for one of said systems of units, and a third scale for indicating a fine scale range of magnitude for the other of said systems of units, said third scale operative to move at a different rate than said second scale, and including a window for providing simultaneous viewing of a portion of each of said second and third scales, said method comprising:
-
manually adjusting the tool to a desired coarse value by causing said tool to position an indicator adjacent to a selected value on said first scale using said first set of coarse scale divisions or said second set of coarse scale divisions; and manually adjusting the tool to a desired fine value by causing said tool to adjust at least one of said second and third scales to a position where the portion of said second and third scales viewed in said window indicates said desired fine value in the respective system of units of said second and third scales. - View Dependent Claims (16)
