Abstract
A vacuum cleaner having the combined features of a canister and upright type vacuum cleaner with the canister mounted for tilting movement on a housing of a floor or nozzle unit which contains a rotatably mounted brush. A single motor is used to power a fan which creates the vacuum in the canister and to apply power to the brush through a belt and pulley assembly mounted in the floor unit housing. A hose extending from the canister is connectable and disconnectable from the floor unit housing so as to provide for above the floor cleaning when the hose is disconnected and the appropriate tools are attached thereto. When the hose is connected into the housing, the vacuum is applied to the vicinity of the brush. A mechanism for disengaging the motor from the belt and pulley assembly when above the floor cleaning is selected is provided by a cam member rotatable with the canister and a pulley asembly which is part of the belt/pulley brush drive assembly. The pulley assembly is movably mounted and biased in one direction by the belt. The cam member is engageable with the pulley assembly and moves it against the bias in the opposite direction to disengage it from the motor drive shaft. A switch is also mounted on the canister and is actuated from an 'off' position when the canister is upright to 'on' positions by a cam surface on the floor housing unit which is engageable with the switch such that the vacuum cleaner motor is 'off' when the canister is upright and 'on' when the canister is tilted forward and the brush is disconnected for above the floor cleaning operations or rearward when the motor shaft is in driving relationship with the belt/pulley assembly for floor cleaning operation.
