Title: A process for the internal coating of barrels and the like
IPC: B05D7/22
Filed: 1948-11-08
Abstract: A barrel or other like hollow body having its interior accessible only through a restricted orifice is coated internally by a process which consists in introducing into its interior a predetermined quantity of coating material in a fluid condition and a plurality of balls having hard and heavy cores covered by relatively flexible material and then effecting uniform distortion of the coating material over the inner surfaces of the body under resilient pressure of the balls by rotating the body about two axes at right angles to each other.  The inner surfaces of the body may be subjected to a preliminary cleaning and then to etching, sandblasting and the like. The quantity of coating material used is preferably not in excess of that required to form the coating and after a coating has been applied or between successive coatings the coating may be subjected to a hardening process as by heating.  The balls may have a core of metal or glass and an outer covering of rubber, a convenient size being about 1/2 inch and the quantity may vary from 2 to 5 or 10 per cent of the volume of the body.
