Abstract
An effluent metering system includes an adapter connectable between the air outlet port on a vacuum cleaning appliance and a supplemental effluent metering device. The adapter preferably has a tubular shell which defines an inlet for receiving a flow of air discharged from the air outlet port. The adapter also has a pair of outlets. A first fluid passage in the shell connects the inlet with a first one of the outlets for exhausting air into a filter. A second fluid passage in the shell connects the inlet with a second one of the outlets for exhausting air into the supplemental metering device.
Claims20
In a vacuum cleaning appliance having a housing with an opening through which matter is a drawn by a vacuum and an outlet port through which matter drawn into the housing is discharged outwardly thereof into a collection receptacle, the improvement comprising an adapter interchangeable with the collection receptacle for connecting an effluent metering device and a supplemental effluent metering device to said air outlet port, said adapter comprising:
- a tubular shell defining an inlet for receiving effluent carrying air discharged from the outlet port of said vacuum cleaning appliance,
- a first outlet for exhausting air into said effluent metering device, and
- a second outlet for exhausting air into said supplemental effluent metering device;
- and
- means for connecting said first outlet to said effluent metering device and said second outlet to said supplemental effluent metering device externally of said housing to facilitate observation of effluent received in said effluent metering device and said supplemental effluent metering device.
An effluent metering device for demonstrating the amount of effluent material discharged through an outlet port on a vacuum cleaning appliance when matter drawn internally of said appliance is exhausted outwardly in a flow of air through said outlet port, said effluent metering device comprising:
- an adapter having an inlet engageable with an air outlet port on a vacuum cleaning appliance and a first outlet engageable with a supplemental effluent metering device, said adapter defining a passageway through which air exhausted from said outlet port flows between said inlet and said first outlet, said adapter having a second outlet in fluid communication with said passageway;
- and
- filter means operatively associated with said adapter for removing effluent material from air flowing through said second outlet and located externally of the vacuum cleaning appliance to facilitate observation of effluent material removed by the filter means.
An effluent metering system for providing an indication of the amount of effluent material removed by a vacuum cleaning appliance, said effluent metering system comprising:
- a first effluent metering device having a first inlet engageable with an air outlet port on a vacuum cleaning appliance and a first outlet, said first device having a passageway through which air flows between said first inlet and said first outlet, said first device having a second outlet in fluid communication with said passageway, and first filter means for removing effluent material carried in a flow of air through said first outlet;
- and
- a second effluent metering device having a second inlet engageable with the second outlet on said first effluent metering device, said second device having a third outlet and a passageway through which air flows between said second inlet and said third outlet, and second filter means for removing effluent material from a flow of air through said third outlet,
- at least one of said first and said second filter means including means for visibly demonstrating the amount of effluent material removed thereby while the vacuum cleaning appliance operates.
