Mechanical powder flow diverting device

For use in an apparatus for the sequential electrostatic coating of individual members, a flow switching device, said flow switching device comprising a supply line having a continuous powder-gas admixture supply, a delivery line for receiving the powder-gas admixture for directing the same against a member to coat the member with powder, a return line for receiving the powder-gas admixture when a member is not in position to be coated, a diverter line having one end continuously connected to said supply, switch means for selectively positioning the other end of said diverter line into alignment with said delivery line and said return line, said flow switching device being improved by said delivery line and said return line each having incorporated therein adjacent said diverter line means for providing continuous gaseous flow therethrough even when said diverter line is not associated therewith for eliminating the customary dead air resistance to flow of the powder-gas admixture when said diverter line is initially shifted into communication therewith.
