Abstract: A method and apparatus for spraying paint and similar coatings. In one form the paint is sprayed at low pressure from a flat fan nozzle. A flat fan of air impinges upon the fan of paint at an angle of from 30*-70*. The air atomizes the paint to form a soft spray with low-forward velocity. In another form of the method, two fans of paint are projected toward one another at an angle and an air fan is directed along the bisector toward the zone of intersection. The air fan atomizes both streams of paint. An electrode can be placed in the air stream to ionize the air stream which in turn charges the paint particles. The width of the paint spray pattern is varied by varying the included angle of the air fan. A spray gun is disclosed having two tubular paint nozzles for projecting two fan-shaped fans of paint. An air nozzle is mounted between the paint nozzles for projecting a fan of air against the paint fans to atomize the paint. The air nozzle is adjustable to provide air fans of different angles for varying the width of the paint spray pattern. An electrode is disposed in the air nozzle for ionizing the air stream. This electrode is energized through a resistor and flexible cable. The cable is spring-urged toward the resistor so that when the resistor is removed, the cable shifts causing a safety switch to open deenergizing the gun. When a nozzle mounting member is removed, the cable and surrounding tube are shifted forwardly to automatically close a valve to seal off the air and electrical conduits. Removable caps are provided on the ends of the tubular paint nozzles for facilitating cleaning of the nozzles.

Abstract: A hydraulic pump and double acting air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. A pilot valve operated by the air piston controls one operating valve for the cylinder and a pilot relay valve. The pilot relay valve controls another operating valve which is in reverse phase with respect to the first operating valve. The piston operated pilot valve has a snap action feature so that the pilot valve, the pilot relay valve and the operating valves all reverse condition abruptly with a minimum dwell to provide a smoother power transmission.

Abstract: A fluid operated system of modular guns for extruding or spraying liquids such as molten adhesives. The system includes multiple guns in the form of readily removable cylindrical modules that mount in apertures of a fixed service block or manifold which receives the supply lines for the liquid and the gun operating pressurized fluid. The service block and guns have passages which register when the system is assembled whereby the guns may be easily removed from the fixed service block and replaced without disconnecting any fluid lines or other service equipment.

Abstract: A modular apparatus for heating circulating liquids such as paint. The apparatus has a heater module that may be heated internally to a high temperature by electrical energy for example, and one or more interchangeable circuit modules having a relatively high thermal conductivity and positioned face to face against the heater module in heat transfer relationship therewith. Each circuit module has a group of generally parallel internal passages formed for example during extrusion and interconnected in pairs at their ends so as to define a sinuous circuit for liquid between inlet and outlet ports. One circuit module may be secured on each opposite face of the heater module with the two respective groups of passages interconnected through the interposed heater module to form a continuous series connection between the two circuit modules. Two or more such units may be ganged with a series circuit connection to enlarge the circuit and increase the volumetric capacity.

Abstract: A system for melting thermoplastic material and supplying the molten material under pressure and at a controlled temperature to one or more applicators. The material is melted in a melting tank and pumped from there through a filter into a manifold for distribution. The pump is a single piston, double acting, sealless pump and is driven by an air motor including appropriate air valves and valve controls. From the manifold the molten material is distributed to one or more heated, insulated hoses, each of which is to be connected at its opposite end to an applicator. The temperature of the material in the melting tank and in each hose is separately thermostatically controlled.
