发明名称 Brush mounting and torsion spring support for powered nozzle
摘要 A vacuum cleaner nozzle is provided having resilient means, disposed between it and its handle, to prevent displacement of the nozzle from the floor during cleaning and also having a litter collecting brush that is spring biased into floor engaging position and height adjustable so that the nozzle is usable on bare floor and carpeted surfaces. Height adjustment is occasioned by a reciprocal bar having dimpled camming surfaces formed integrally in its top surface, with this bar being lever actuated and including an indicating means to guide the user during cleaning.
