Abstract
Abstract A hollow axially short and generally cylindrical body is provided and is open at one end. The other end of the body includes a closure end wall having a central portion which is displaced longitudinally of the body approximately one-half the length thereof toward the open end of the body and a pair of front and rear generally cylindrical aligned spool core sections are disposed within the body in front to rear aligned relation. The front and rear spool core sections include rear and front radially inwardly projecting annular end walls and front and rear radially outwardly projecting circumferential flanges. A generally cylindrical hub including a radially outwardly projecting forward end flange is also provided and the annular end walls of the spool sections are journalled on the hub, the forwardly displaced portion of the rear wall of the body being centrally apertured and a threaded fastener being secured through the hub and the rear wall central portion.
