Patent number: 4301971Abstract: A spray gun for spraying of liquids utilizing compressed air includes a molded casing which contains within a sealed pressurized portion thereof, an electric motor and an air compressor driven by it. A manual trigger sequentially controls an electric switch for the motor and a needle valve for the discharge nozzle such that the motor and compressor are started before liquid is admitted to the nozzle, and are operated after liquid flow to the nozzle has been terminated. A diaphragm-type inlet check valve communicates with a pressure chamber of variable size forming a part of the air compressor, a second diaphragm providing both the movable wall of the pressure chamber as well as the movable element of an outlet check valve built therein which conducts pressurized air into the pressurized portion of the casing, passing across the motor enroute to the nozzle.Type: GrantFiled: August 23, 1979Date of Patent: November 24, 1981Assignee: Cornelius Engineering Center, Inc.Inventors: Richard T. Cornelius, deceased, by Richard G. Lareau, executor

Patent number: 4222525Abstract: An arrangement for spraying liquid from a bottle comprises an air pump and a member which actuates the pump when a spraying action is desirable. The air flow is transmitted into the interior of the bottle to pressurize the liquid and urge the latter into a liquid outlet conduit which has a lower end extending into the liquid in the bottle and a discharge end outside the bottle. The arrangement is further provided with an element for spraying the liquid when the latter under the pressure supplied into the bottle enters the discharge end of the outlet conduit.Type: GrantFiled: June 12, 1978Date of Patent: September 16, 1980Assignee: Wella AktiengesellschaftInventor: Bodo Hildebrandt

Patent number: 4208013Abstract: A portable chemical spraying apparatus has an electric motor/compressor mounted inside of two halves of a lightweight housing. A compressed air output of the motor/compressor connects directly to a compression chamber. Compressed air inside of the compression chamber moves through the venturi of a nozzle into a mixing chamber. The mixing chamber opens to atmosphere through a vortex of compressed air received via spiral passages connecting to the compression chamber. Chemicals may be drawn into the mixing chamber through a needle, which may perforate a seal of a disposable chemical container at the time the chemical container is connected to the portable spraying apparatus. Simultaneously, the needle seals with a metered conduit which extends to the inside bottom of the chemical container.Type: GrantFiled: March 7, 1977Date of Patent: June 17, 1980Assignee: Micro-Gen Equipment CorporationInventors: Bobby W. Coleman, John R. Frassanito, Richard O. Norman, James G. Parke

Patent number: 4033511Abstract: A portable atomizer includes a liquid dispenser, a reciprocating pump for supplying compressed air to the dispenser, and a motor for driving the pump. Upon operation of the motor, compressed air is delivered directly to the dispenser from the pump to automatically atomize liquid in the dispenser and instantaneously spray atomized liquid and compressed air from an orifice in the dispenser.Type: GrantFiled: November 24, 1975Date of Patent: July 5, 1977Inventor: Edward B. Chamberlin

Patent number: 3997115Abstract: A portable atomizer includes a housing in which a battery and a motor powerable by the battery are mounted. A receptacle for liquids and a vacuum pump operatively connected to the receptacle are also mounted within the housing. The motor shaft carries a bladed fan for rotation therewith externally of the housing and a sector gear engagable with a gear on the vacuum pump so that the pump can be cyclically actuated to discharge liquid into the path of the fan.Type: GrantFiled: March 10, 1976Date of Patent: December 14, 1976Assignee: Lawrence Peska Associates, Inc.Inventor: Mariano B. Licudine
