Abstract
A portable vacuum cleaner having a nozzle extending from the housing and a dust bag supported within the nozzle. The nozzle consists of two longitudinal sections one of which is an extension of the housing and the other of which is removable, to permit insertion removal and replacement of the dust bag, and may also be locked in position. To lock the removable portion of the nozzle, there is a retainer for the housing end of the removable section and a tubular member which has a modified breech block type of locking flange at its front. The inner portion of the tubular member supports the dust bag in the nozzle. The locking flange is placed on a tab extending from the section of the nozzle which is an extension of the housing and receives a tab from the removable section of the nozzle. The locking flange is then rotated to effect the lock at the front end of the nozzle thereby locking the tubular member into the front end of the nozzle and locking the removable section of the nozzle in place. An end nozzle is provided having an opening communicating with its own tubular extension which is a removable fit into the tubular member which carries the locking flange. The end nozzle has an apron which covers the front end of the nozzle to cover the locking flange and present a smooth appearance.
