ABSTRACT:
An arrangement for mounting a motor blower assembly in a canister vacuum cleaner uses a pair of resilient rubber rings, one each on the front and rear of the assembly, to isolate the motor from the vacuum cleaner housing. The front ring goes over the front of the fan casing and is trapped within the housing, while the rear of the motor has attached thereto an adaptor which fits within the complementarily shaped rear rubber ring. This rear rubber ring in turn fits within a complementarily shaped motor support, which is attached to a support abutment within the housing. In order to accommodate different size motors within the same housing and utilize the same mounting components, the support abutment is pre-drilled at various locations to accommodate the different size motors. Thus, the only fixed attachment to the housing is the rear support, which is isolated from the motor blower assembly by the rear rubber ring.
