Abstract
A brushroll having a pulley driven spindle with an end assembly at each end rotatably mounting the spindle in a vacuum cleaner nozzle. On the pulley end of the spindle, a projecting pin is knurled at one end and inserted into the end of the spindle. An outboard portion of the pin is threaded. The knurling on the pin forms an abutment shoulder outboard of the end of the spindle. The drive pulley is threaded onto the threaded end of the pin until it contacts a bearing and presses it against the abutment shoulder, so as to prevent the pin from being jacked out of the spindle when the pulley is threaded onto the pin.
