Description
April 18, 1939. J. KAMPSCHULTE 'ATOMIZER FOR LIQUIDS Filed Feb. 11', 1938 In re nlor 6; A fformsy Patented Apr. 18, 1939 UNITED STATES bATEN'i' OFFiCE 1 Claim.
This invention relates to an atomizer for liquids, especially liquid floor polish, in which the liquid to be atomized is placed under pressure in a container by means of an air pump screwed into the container and, after the opening of a spraying valve is forced through a feed conduit to a spraying nozzle and atomized thereby. The feed conduit consists of a rigid tube and of a flexible portion the head of which always drops to the lowest point of the container irrespectively of the position of the container, so that it is possible to spray downwards, upwards and sideways even when there is only a small quantity of liquid in the container. The movable part of the feed conduit could hitherto not be made with the necessary flexibility, because if the hose is of natural rubber it is dissolved by liquid floor polish and a flexible metal tube is not sufflciently flexible.
According to the invention the flexible part of the feed conduit is a tube made of a synthetic rubber which is very flexible and not attacked by liquid floor polish. To prevent the tube from wrapping around the rigid tube and jamming, a thin sheet metal wall is arranged in the container, and prevents the tube from wrapping itself around the rigid tube.
An embodiment of the invention is illustrated by way of example in the accompanying drawing, in which:
Fig. 1 shows the atomizer partly in longitudinal section and partly in elevation,
Fig. 2 shows in elevation the handle end of the air pump.
Into one end of the atomizer container 11 an air pump b is screwed. At the other end of this container a valve is arranged with a spraying nozzle 11 in which a distributor e is enclosed. In the seat of the valve 0 there is a packing ring 7 and a valve piston 9 connected with a valve stem i is under the influence of a spring h to close the valve. The valve stem 1' has a head I on its end situated outside the container.
In the container a a thick inclined tube In is rigidly soldered at one end to the casing of the valve 0 and at its other end to the inner side of the container wall. This tube m which forms part of the feed tube has a short connecting nipple n onto which one end of a tube 0 of synthetic rubber is slipped, whose other end carries a heavy metal suction head 1? whose bottom is formed by a strainer. In the tube 0 accommodating the valve stem 1 and spring h a packing q is arranged at the point at which the valve stem passes out through the container wall and this packing tightly packs the valve stem against the atmosphere. A lever r is oscillatably mounted on a hinge s on this packing outside the container. This lever 1' carries a fork t which engages under the head l of the valve stem 1'. To prevent the synthetic rubber tube 0 from wrapping around the rigid tube m a partition u of thin sheet metal is fixed to the tube m and to the inner side of the container wall.
The atomizer is operated in the following manner:
After unscrewing the air pump 2), the container a is filled through the screw hole to about three-qua rters full with the spraying liquid. The pump is then replaced and the liquid in the container placed under pressure by the same. Hereupon the atomizer is held inclined to the point to be sprayed, the air pump serving as handle. The operator then grips the lever r with the hand holding the pump and pulls this lever towards the pump. The valve stem, under whose head Z the fork t of the lever r engages, is thus moved against the action of the spring 72 and opens the valve 0, g, whereupon the liquid escapes through the nozzle 01 in finely divided state. The flexible feed tube 0, owing to its heavy metal suction head p always drops to the lowest point of the container irrespectively of the position of the atomizer, so that even very small quantities of liquid can be sprayed.
I claim:
An atomizer for liquids, especially floor polish, comprising in combination, a liquid container, an air pump serving as handle detachably connected to one end of said container and adapted to produce pressure in said container, a discharge nozzle at the other end of said container, a feed conduit in said container and consisting of a rigid tube extending through said container and leading to said nozzle and of a flexible tube of synthetic rubber branching from said rigid tube, a valve for said nozzle located in said tube, a control lever for said valve at the end of said rigid tube remote from said valve and projecting in proximity to and adapted to be gripped with said air pump to hold open said valve when the atomizer is in use, a heavy metal suction head on the free end of said flexible tube and adapted to always drop to the lowest point of the container irrespectivel'y of the position in which the container is held, and a thin sheet metal wall arranged between said rigid tube and the inner wall of said container and adapted to prevent the flexible tube from wrapping around the rigid tube and the suction head from wedging between said rigid tube and the container wall.
