Improved Wheel Gages and their Application

IMPROVEMENTS IN COMBINED GAGES W620-1P & W620-2P:

• Extended reference edge for measuring flange thickness to afford better measuring accuracy.
• Replace the fish scale with a more useful standard scale. One centered on the front and one measuring from the edge on the back. The one from the edge on the back can be used by a carman for 2″ safety devises and 4″ hand holds.
• Provide 3/4 and 1 inch holes for shells & spalls.
• Provide 11/16 Rim Thickness for FRA.

IMPROVEMENTS IN WHEEL DEFECT GAGES W620-1 & W627-2:

• Make center divider long enough to assure that the gage sits perpendicular to wheel.
• Provide standard scale on front for measuring slid flats.
• Provide scale on back for 4″ hand holds and 2″ safety devices.
• Provide 3/4 and 1 inch holes for shells & spalls.

IMPROVEMENTS IN SIMPLIFIED WHEEL GAGE W620:

• Provide 11/16 graduation for the FRA.
• Provide for all AAR Rim thickness requirements.

IMPROVED WHEEL DEFECT GAGE

• THE IMPROVED WHEEL DEFECT GAGE GREATLY REDUCES THE NUMBER OF CARS IMPROPERLY BAD ORDERED FOR THIN FLANGE!
• THE IMPROVED WHEEL DEFECT GAGE CHECKS MANY CURRENT REQUIREMENTS NOT CHECKED BY THE OLD WHEEL DEFECT GAGE.
