Claim 8
Dependent Claim
170 words
In a hand held vacuum cleaner comprising a first unit including motor, fan and handle and a second unit projecting in front of the first unit and including a hollow dust-receiving cup having a cup mouth at its front end, tiltable nozzle means comprising a unitary bearing body within the front end of the dust cup behind said cup mouth and extending between the side walls and the top and bottom walls of the cup, a nozzle body projecting from the cup mouth and rotatably cradled in cradling means formed in the bearing body, said cradling means being internal to the cup and external to the nozzle body, said nozzle body being retained from the interior of the cup by said cradling means, said nozzle body substantially filling said cup mouth in all said angular orientations, retainer means on the sides of the nozzle body and rotatably engaging corresponding sides of the cup or cup mouth, the nozzle body being retained from the exterior of the cup by said engagement.
Claim 9
Dependent Claim
31 words
A device as in claim 6, a valving mouth formed in said bearing body, a valving flap over said valving mouth and normally closing off the interior of the dust cup.
Claim 10
Dependent Claim
