You might have more luck trying to get a copy of his death certificate from the state of Pennsylvania:
PA Dept. of Health
Division of Vital Records
P.O. Box 1528
New Castle, PA 16101
724-656-3100
www.dsf.health.state.pa.us/health/site

The Carnegie Library has few, if any, obits indexed for the period between 1913 and 1963. Once you know the exact date of death from the death certificate, you will be able to look up a specific newspaper issue for the obit if you want.
