Bells, Vibrating, 3-Inch and 10-Inch Submitted by Chas. Cory Corporation

Abstract

The subject bells as received were first set up in standard test circuits and their current consumption and power factor measured, while operating at rated voltage and frequency. The usual tests for endurance and temperature rise of the windings at ambient temperature of 40 deg C. then followed. Each was then tested for shock integrity, audibility range, insulation resistance and dielectric strength. The tests was concluded with an inspection of the materials, design and workmanship.
