Abstract
A vacuum cleaner brushroll having skirted, one piece plastic ferrules inserted into the ends of a tufted, wood spindle so that the ferrule skirts embrace the spindle end portions to prevent the ferrules from loosening upon expansion of the spindle due to moisture. The skirts are drilled to permit angled tufting to be inserted very near the spindle ends with the tufting extending axially and radially outwardly beyond the spindle ends to provide improved edge cleaning and create a wider cleaning path compared to conventional brushroll designs.
Claims9
In a tufted, vacuum cleaner brushroll including a spindle having a longitudinal rotation axis, stub shafts extending from the ends of said spindle, and end members and bearings mounted on said stub shafts, the improvement comprising one-piece plastic ferrules at the ends of said spindle, each ferrule having a hollow pin that receives one of said stub shafts and is fixed in an end of said spindle, a skirt embracing the end portion of said spindle, and a web between said pin and said skirt, and wherein tufts of said brushroll extend outwardly through said skirt.
In a vacuum cleaner brushroll including a spindle having a longitudinal rotation axis, tufts extending outwardly from said spindle, and end assemblies for rotatably mounting said brushroll in a vacuum cleaner, the improvement wherein at least one of said end assemblies comprises:
- a) a one-piece plastic ferrule having a skirt embracing an outer end portion of said spindle, a hollow pin fixed in an end of said spindle, and a web connecting said skirt and pin,
- b) a stub shaft fixed in said pin and extending therefrom, and
- c) a bearing assembly on an extending end of said stub shaft.
A one-piece plastic ferrule for a vacuum cleaner brushroll comprising a center hollow pin, a first radial wall extending outwardly from said pin, an axial wall projecting in an axially outward direction from said first radial wall to form a mouth at one end of said ferrule, a second radial wall extending outwardly from said axial wall, and a peripheral skirt projecting from said second radial wall, said skirt being spaced radially outwardly from said axial wall to form a recess which opens in an axial direction opposite to said mouth.
