  • Patent number: 4014540
    Abstract: A ball and socket joint for a swing for providing simultaneous swiveling and pivoting motion in any direction. The ball is preferably molded with an inner core and an outer shell of different colored materials. As material from the outer shell is worn away in normal wear, exposure of the inner core indicates visually the extent of wear which has taken place. A retainer member placed in load bearing relationship between a support bolt for the swing and the ball is intentionally made larger than the opening at the base of the socket to prevent the swing from dropping in case of breakage of the ball.
