Abstract
A pneumatic, syphon type apparatus particularly advantageous for dispensing and applying viscous materials in a spray form features, in a preferred embodiment, a throwaway eductor assembly which slip fits to the delivery end of a tubular structure adapted for connection to and delivery therethrough of air or other gaseous fluid under pressure. The eductor assembly comprises a tubular adapter extended at one end by an eductor tube and at the other by an applied nozzle and a syphon tube connected therewith to open to its interior adjacent the nozzle and at right angles thereto. In use of the apparatus the syphon tube is introduced to a body of the material to be dispensed as the end of the adapter including the nozzle is releasably coupled to the discharge end of the tube which is connected to a source of air under pressure. In preferred embodiments the tubular structure for delivering air, under pressure, to and through the nozzle of the eductor assembly mounts apparatus for the quick releasable coupling thereto of the container of a quantity of the material to be dispensed and applied by way of the eductor assembly in a spray form. The apparatus enables a quick substitution of one eductor assembly for another and one container of material for another.
