Patent number: 4291769Abstract: New foam fire extinguishing unit for incorporation into rescue cars is described. It consists of a container which contains a liquid adapted to be used for foam production without adding further ingredients. To the container a device is connected which feeds the fire extinguishing liquid under pressure from the container to a hand-held foam generating nozzle. The device may comprise a motor driven pump or an air pressure device. The foam fire extinguishing unit may be a mixture of water and "Light Water". The new foam fire extinguishing unit can also be used as a stationary unit in work shops and warehouses.Type: GrantFiled: October 22, 1979Date of Patent: September 29, 1981Inventor: Erich Muller

Patent number: 4257540Abstract: A hand-held, battery-powered dispenser for pumpable materials such as lubricants and, in particular, lubricating grease, comprising a handle, a head, a barrel secured to the head holding a supply of lubricant and a plunger slideable within a bore in the head. The bore intersects an inlet port in communication with the barrel and is in communication with an outlet port for the delivery of the lubricant under pressure. The plunger is reciprocated in the bore through a pressure stroke and a return stroke by a motor in the handle operating a drive mechanism in the head connected to the plunger. The user operates the motor by actuating a switch in the handle which completes a circuit connecting rechargeable batteries in the handle with the motor. A flywheel in the drive mechanism permits significant reductions in the size and weight of the motor and batteries so that the dispenser can be light enough and small enough to be hand-held during operation, yet capable of delivering the lubricant under high pressure.Type: GrantFiled: October 26, 1978Date of Patent: March 24, 1981Assignee: McNeil CorporationInventors: Jerome B. Wegmann, Norbert F. Cook

Patent number: 4238055Abstract: A powered atomizer that repeatedly actuates a conventional manual pump-type atomizer. The powered atomizer is a motor driven unit contained within a housing which holds the atomizer spray head and pump stationary, and provides a mechanism to reciprocate the atomizer container relative to the stationary spray head and pump to actuate the atomizer. The housing is comprised of two separable sections that permits disassembly of the housing and replacement of spent containers. The atomizer container is reciprocated in the housing by means of an electric motor with a motor shaft. The rotary motion of the motor shaft is transformed into reciprocating vertical translatory motion by a cam and follower mechanism. An on-off switch controls the supply of power to the motor, and the container returns to its lowermost position when the motor is stopped, so that it can be manually operated.Type: GrantFiled: April 24, 1979Date of Patent: December 9, 1980Assignee: Staar S.A.Inventor: Marcel J. H. Staar

Patent number: 4235377Abstract: A portable pump spraying device includes a container for the liquid to be sprayed, a housing positioned above the container having a spraying chamber, a pumping unit to elevate the liquid to the spraying chamber, and a rotating disc in the spraying chamber to attenuate and impel the liquid by centrifugal force through an egress port in the housing. Interceptor baffles within the spraying chamber finely trim the liquid spray as it leaves the egress port and direct the excess liquid back to a reservoir for recirculation. The pumping unit includes a rod that is reciprocated by an eccentric on the rotating shaft on which the disc is mounted. The rod acts as a piston which on its suction stroke withdraws liquid from the container and on its compression stroke discharges the withdrawn liquid and forces it through a nozzle onto the disc in the spraying chamber.Type: GrantFiled: November 29, 1978Date of Patent: November 25, 1980Assignee: The Wooster Brush CompanyInventors: Howard C. Davis, Donald L. Cooper

Patent number: 4162037Abstract: An automatic sprayer comprising a spray body, a prime mover mounted to the spray body, a geared eccentric drive operatively associated with the prime mover, a nozzle body to be driven into oscillating motion by means of the a geared eccentric drive, whereby treatment liquid contained in a container is sprayed by oscillating motion of the nozzle body. Spraying may be carried out upon oscillating motion of the nozzle body, thus resulting in efficient dispersion of liquid.Type: GrantFiled: July 18, 1977Date of Patent: July 24, 1979Inventor: Masaya Koyama

Patent number: 4000856Abstract: Apparatus for producing a fog/spray as a coating medium for articles. The apparatus comprises a trigger actuated gun having an inlet connected to a source of hydraulically pressurized spray fluid, wherein the pressurizing medium and drive source is itself driven by a compressible fluid such as air. The compressible fluid supply line to the drive source has mounted therein a flow sensing valve which actuates an air valve for controlling atomizing air supply to the applicator gun. The atomizing air supply to the applicator gun is coupled into a gun chamber downstream of the spray orifice so that fluid sprayed through the orifice becomes fogged by the pressurized air in the chamber.Type: GrantFiled: September 2, 1975Date of Patent: January 4, 1977Assignee: Graco Inc.Inventors: Vernon K.
