Thatthe hand jiaintcr liold* nn can only be regarded as proof. Vortex Painter in Use On Metal Building that the proljlem of mechanical painting is more difticultthan imagined by many of those who have offered variousshapes and forms of spraying devices. A few of the characteristic difficulties of paint sprayingare (1) loss of paint, (2) scattering and splashing oversurfaces not to he painted, (3) difficulty in the open airowing to wind interference, (4) pre-dr)ing of the paint to a chalky consistency through eva])oration of its volatileoils while in the air. With these difficulties in mind, a paint spraying etiuip-nunt has been perfected by the Vortex Manufacturing Com-pany, Cleveland, Ohio, and placed on the market. Theequipment includes a jwrtable air compressor, paint tankand a nozzle. Ihe \ nozzle has two openings, acentral opening for paint and an annular opening aroundthe center from which the air is discharged under a pressureapproximating 60 lb. per ?q. in. There are separate con-duits for air and pai
