摘要： An apparatus for transferring electrically conductive coating materials such as water-based paint from a source to an electrostatically charged dispenser includes first and second shuttle devices and two large reservoir, piston pumps each having structure for preventing contamination of the coating material and pressure build-up at their piston heads. The first shuttle device is movable between a neutral position wherein it is electrically isolated from a filling station connected to the coating material source, and a transfer position wherein coating material is transmitted to one of the piston pumps through a coupling device which connects the filling station and first shuttle. The second shuttle device is movable with respect to a discharge station between a neutral position wherein the second shuttle is spaced from the discharge station, and a transfer position wherein coating material is transmitted from the filled piston pump, through another coupling device which connects the second shuttle and discharge station and then to the second piston pump for transmission to one or more electrostatic coating dispensers. Movement of the shuttle is controlled to maintain one of the shuttles in the neutral position while the other is at the transfer position.

摘要： An apparatus for transferring electrically conductive coating material comprises a filling station having a first coupling element connected to a source of the coating material and a shuttle carrying a second coupling element which is movable with respect to the filling station between a paint transfer position in which the coupling elements engage and a neutral position physically spaced from the filling station. The shuttle, in turn, is connected to the reservoir of a piston pump which communicates with one or more air operated or air assist spray guns. A high-voltage power supply is connected to the metal body of the piston pump to charge the electrically conductive coating material immediately before it is supplied to the spray gun. A pneumatic/mechanical control system controls the operation of the shuttle, pump and electrostatic power supply to ensure that a voltage block is maintained between the source of coating material and the electrostatically charged coating material which is discharged from the spray gun.

摘要： A method and apparatus for applying liquid coating materials, adhesives or other liquids is provided in which the liquid material is pumped from a source through a pneumatically operated, diaphragm-type pressure regulator which discharges the liquid at a controlled pressure to a dispenser such as a spray gun. Pressurized air from a pneumatic panel or other air supply device is transmitted to one side of the diaphragm in the pressure regulator through a one-way valve such as a check valve which protects the pneumatic panel from an upstream flow of liquid from the pressure regulator in the event of a failure of its diaphragm. A fluid bleed device such as a choke is located downstream from the check valve and upstream from the diaphragm in the pressure regulator to vent pressurized air located therebetween, and to permit the escape of at least some of the liquid flowing upstream from the pressure regulator in the event of a failure of its diaphragm which provides a visual indication of the failure of the diaphragm.

摘要： A reversing-ratchet wrench for use, for example, with various interchangeable socket heads. One end of the wrench serves as a handle and the fulcrum end has an opening that defines internal ratchet teeth and that receives a pawl carrier rotatable about the axis of turn of the wrench. The ratchet teeth are engaged by a double pawl pivotally mounted in a lateral slot cut in the side of the pawl carrier, the pawl being urged to either a forward drive or reverse drive position of engagement with the ratchet teeth by a selector mechanism. The selector mechanism includes a hub received in a central bore in the pawl carrier and a pivotal selector button on the upper end of the hub. The lower end of the hub has a lateral opening that receives a spring-loaded pawl-operating plunger. The plunger has a length greater than the depth of the lateral opening and extends into the slot in the pawl carrier to resiliently engage the double pawl and also to secure the selector mechanism in the pawl carrier.

摘要： A wax spray gun and spray nozzle for discharging an atomized stream of molten wax onto a vehicle body component or other substrate comprises a gun body having an atomizing chamber within which an internal wax spray nozzle and atomizing cap are located. A stream of atomizing air is tangentially directed into the atomizing chamber to form a rotating, swirling stream of atomizing air which is accelerated through a venturi inlet formed in the atomizing cap to impact and thoroughly atomize molten wax discharged from the internal spray nozzle. The atomized stream of molten wax is then discharged from the gun body into an external nozzle which preferably comprises a nozzle body having a wall formed with external threads which carry a coil spring. A flat is formed in the wall of the nozzle body with a discharge opening therein over which at least two spaced spring wires are positioned in the path of atomized molten wax emitted from the discharge opening. The atomized molten wax contacts the spring wire and is further atomized and deflected in a diffuse pattern for deposition onto a substrate.

摘要： An apparatus for transferring electrically conductive coating materials, such as water-based paint, from at least one source to one or more coating dispensers or spray guns for discharge onto a substrate includes two "parallel" flow paths, each having a large reservoir pump, which transmit coating material to a common valve which, in turn, switches flow to the coating dispensers from one flow path to the other. Each parallel flow path provides a voltage block between one or more sources of coating material and the electrostatically charged coating material discharged from the spray guns to ensure that there is never a completed electrical path between the source of conductive coating material and the charged coating material during a coating operation. Additionally, a rapid and efficient color change capability is provided for the entire system which permits different colored coating materials to be dispensed from the apparatus herein with minimum downtime of the coating operation.
