SV-70 MEANS FOR MOUNTING FLOOR PICKUP NOZZLE TO DOLLY FOR VACUUM CLEANER A mounting means secures a floor nozzle to the front of a wheeled dolly base which supports a vacuum cleaner that is connected to the outlet of the nozzle by a flexible hose. The mounting means includes a plate having struts extending therefrom to opposite ends of the nozzle. A rearward extension of the nozzle, disposed midway between the nozzle ends, is connected directly to the plate by a manually operable height adjusting means. An upwardly offset rearward facing ear on the plate is received by a slot that is centered at the front of the dolly base. Two of the swivel-type wheel units that support the base are each provided with a vertical pivot shaft that extends upwardly into and is frictionally held in a wheel well on the base. Before entering the wheel wells, the pivot shafts pass through apertures in the plate thereby fixing the nozzle against all forces in a horizontal plane.
