Magnetic Gauge

The magnetic gauge enables determination of exact dimensions between two surfaces that are completely hidden when the condition for measuring the required dimension exists.

Gauge 1, at A, includes telescoping numbers 2...4 that are formed of a magnetic material with nonmagnetic collars 2a...4a. The lower surface of member 4 at 4b can carry double sided tape or other adhesive for use on nonmagnetic surfaces. Applications are shown at B and C. At B, it is necessary to maintain a clearance of .001 to .005 inches between sensing roller 5 and sensing cover 6 at the point of contact 7. The assembly further includes document cover 8 cooperating with adjusting screw 9 to establish the required clearance at 7. Gauge 1 is placed in position indicated by arrow 10 in contact with covers 6 and 7 when cover 8 is closed. Prior to placement, gauge 1 has elements 2...4 extended for a distance that is greater than the length of arrow 10. Upon closure of cover 8, elements 2...4 telescope inwardly to measure the exact dimension between covers 6 and 8. In a typical case, this can be .620 inches nominal. Screw 9 is adjusted to establish the required clearance at 7.

In another case, the cover 6 lift lever 11 is adjusted by adjustment screw 12, contacting document cover 8a when in closed position. It is desirable to maintain a clearance of .125 inches at 13 between sensing cover lift roller 14 and sensing cover 6a. Gauge 1 is placed in position indicated by arrow 15 engag...
