Abstract

373,467. Powder blowers. WALDRON, T. N. and DAVIDSON, P. G., Avon Works, Stratford-on-Avon. Sept. 21, 1931, No. 19827. [Class 18.] A powder blower comprises an air pump 1 the casing of which carries a depending powder container 12. Air is forced by the pump through a valve controlled opening and downwardly into the container so as to impinge on the powder, the powder being thereby agitated and carried upwardly to a discharge nozzle 13 on the container., The valve controlled opening is constituted by a metal tube 4 which passes through the pump casing and a partition 3 therein and which has its inner end closed by a spring-pressed ball and its outer end by a rubber &c. stopper. Air passes from the pump up the tube 4, through a perforation into a compartment 10 which latter communicates with container 12 through an aperture 20. The lid or top wall of the container is provided with an opening with upwardy turned flanges, and the pump casing and the outlet nozzle 13 are soldered to these flanges, the outlet nozzle comprising an inverted, tapering, U-shaped channel member.
