Vacuum cleaner brushroll

摘要

A shaft driven vacuum cleaner brushroll that can be mounted in the nozzle of the vacuum cleaner and directly connected to a shaft of the cleaner's motor drive shaft system. The brushroll features a two-piece drive assembly that simplifies its manufacture and can be engaged on a wood spindle to effectively transmit torque from the vacuum cleaner drive to the brushroll.

主权项

1. A shaft driven brushroll that mounts in a vacuum cleaner and is rotated by direct connection to a shaft of the motor drive shaft system of said vacuum cleaner, said brushroll comprising:
(a) a spindle, (b) a ferrule at one end of said spindle, said ferrule having a skirt around said spindle and a portion seated in said one end, whereby said spindle is captured between said skirt and said ferrule portion, (c) a drive pin inserted through said ferrule into said one end of said spindle, said drive pin having a slot forming a quick connect-disconnect for locking said drive pin to a driver shaft of the motor drive shaft system of said vacuum cleaner, (d) said ferrule and said drive pin have coacting surfaces that lock the two members together, whereby torque is transmitted through said drive pin to rotate said spindle, and (e) bristle tufts projecting out from said spindle with some of said tufts extending through said ferrule skirt.
