Abstract
A vacuum cleaner nozzle having a housing including a top wall. A device for indicating an adjusted characteristic of the vacuum cleaner nozzle is mounted within the housing substantially below the top wall and, in the illustrated embodiment, on a bottom wall of the housing. Structure is provided for causing a selected one of the indicia of the indicator discernible to a user of the vacuum cleaner standing above the nozzle, notwithstanding the recessing of the indicator substantially deeply within the nozzle. In the illustrated embodiment, the structure for causing the indicium to be discernible includes a focus tube formed integrally with the top wall extending to closely adjacent the indicator and having a distal portion configured complementarily to the indicator. In the illustrated embodiment, the device for causing the indicator to be discernible to the user is defined by a synthetic resin magnifier secured to the focus tube so as to be substantially flush with the top wall of the nozzle.
