Felix E. Spurney, 78, a manufacturers representative here for the Butler Manufacturing Company from the mid-1940s until retiring in the mid-1960s, died of arteriosclerotic heart disease Saturday at the Manor Care nursing home in Wheaton.

Butler manufactured products used by the government, such as prefabricated buildings, and Mr. Spurney was manager for government contracts during much of his time with the company.

Mr. Spurney was a native of New York State and a 1923 graduate of Cornell University. He came to Washington in the mid-1930s, then worked as a construction engineer on ship building projects in Louisiana and Alabama before returning here about 1940. He had been a resident of Kensington for about the last 30 years.

He was a member of the Warner Memorial Presbyterian Church in Kensington, the Kensington Historical Society, the Cornell Club of Washington, Congressional Country Club, and the International Club. He was a life member of the American Society of Civil Engineers and a member of the American Society of Naval Engineers.

His wife, the former Elizabeth Sloane, died in 1979. Mr Spurney's survivors include a son, Petr Logan Spurney of Chevy Chase and New Orleans; two daughters, Nancy Elizabeth Hebner of Wilmington, Del., and Susan Taylor of Silver Spring; a sister, Jenny Broadbent of Moodus Conn; nine grandchildren, and two great-grandchildren.
