Sam Felton didn't break any window at Briggs Cago yesterday afternoon but his toss of 56 feet, 3 3/8 inches in special AAU open 35-pound weight throw was the goe-whiz performance of the four-event AAU track meet.

In regular New England AAU competition, Boo Morcom, "the barefoot boy from New Hampshire," won the pole vault championship with a hoist of 14 feet; Rudy Forbert, a barrel-chested Tufts junior, took the broad jump at 21 feet, 6 1/3 inches; and Olympic hammer thrower Bob Bennett won the regular 35-pound weight throw with a loft of 52 feet, 1 7/3 inches.

Falls to Break World Record

Felton, a member of the New York Athletic Association, was ineligible for the New England weight throw. Now a student at the Business School, Sam tried in the special weight event to break Niles Perkins' world record of 58 feet, 7 1/2 inches.

Felton's former teammate here, Pete Hardwood, finished second to Morcom in the pole vault. He did 12 feet, 6 inches. No varsity entires competed, since track coach Mikkola is resting his team for tomorrow's meet at West Point.
