6 Claims.
This invention relates to hand-operated sprayers or atomizers used for distributing liquid insecticides or other liquids, and the invention has for its object the provision of improved, construction enabling better, more effective and positive results than procured withthe types of devices now employed for the purpose.
A particular object. oi the. invention is in the provision of means wherebya. continuous, finely diifused spray may be projectedfrom the devicewith a minimum of pumping, effort on the part of the operator. I obtain. this result by the use of a relatively small diameter piston and a. small diameter piston chamber in co-operation with the use of a relatively large compression chamber for holding a maximum of. air pressure produced by the operation of the piston. I
These and: other features possessed by the device render it highly efficientand exceptionally easy to operate.
In the accompanying drawing wherein a pre ferred embodiment of the invention is shown, Fig. 1 is a longitudinal sectional view through the device on the line II of Fig. 2, looking in the direction of the arrows; Fig. 2 is a front, elevational view thereof on a larger scale, with parts broken away; and Fig. 3 is a sectional View on the line 3-3 of Fig. 2, looking in the direction of the arrows.
In the drawing, I0 indicates an elongated cylinder forming the compression chamber. Located concentrically within the cylinder is an elongated piston chamber I2 within which the piston I I is slidable, the piston being secured at one end of the piston rod I'I. Rod I1 is providedjat its opposite end with an operating handle 20 of conventional form, and also is provided with a stop member I9 to limit the inward projection of piston II within chamber I2.
Piston chamber I2 is of considerably less diameter than the cylinder I0 whereby an annular compression chamber I3 is formed between the outer face of the compression chamber I2 and the inner face of the cylinder ID. This compression chamber is thus of substantial capacity, and permits the storing of a relatively large amount of air under pressure whereby a continuous spray is provided by leisurely backward and forward piston operation. At its inner closed end 2I, the piston chamber is provided with a check valve 22 of conventional construction. The opposite end of piston chamber I2 is flared outwardly and has its end fitted over the edge of cylinder In as shown at I5 and is secured thereto by soldering or otherwise. The flared portion of piston chamber I2 thus serves to close one end of the annular air compression chamber [3 and is internally threaded, as shown at I4, for the reception of a. threaded closure plug I6, said. plug: having a central aperture I8 through which the piston rod I1 is slidable. At the opposite end of, cylinder IIO a cap 23 is secured, said cap being provided with a central. hole or opening 24, in registration with a similar hole 26 of smaller diameter provided. near the upper closed end of'a, flat suction tube 25 which projects down into the cylindrical fluid receptacle 29 attached transversely of cylinder I0- by means of solder 32 or-- other fastening means. An outer cap 28 is posi tioned over the upper closed end of tube 25 and over the inner cap 23.. Said outer cap 23 is provided with a relatively large hole or'aperture 21, in registration with the holes 26 and 24 in tube 25' and inner cap 23 respectively- Cap 28 is secured in position by the solder 33 or by other suitable means. Fluid receptacle 29 is provided with a filler neck 30 whereina closure plug 3| is screwthreaded so that it. may be removed when the receptacle is being replenished with insecticide or other liquid.
It will be noted that the diameter of the piston I I is, according to the present invention, relatively small so that a minimum of manual effort is required to reciprocate the piston within the piston chamber I2. At the same time, the compression chamber I3, consisting of the annular space 0 located between the piston chamber I2 and cylinder ID, as Well as the space located between the end 2| of the piston chamber and inner cap 23 is substantially large, so that a great deal ofair under compression, can be produced within this compression chamber by leisurely or slow strokes of the piston. The result is that by slowly moving the piston back and forth within its chamber I2, a continuous spray of fine mist or vapor is projected out of the aligned openings 24, 26 and 21. At the same time, the size of the entire device is maintained within the usual limits for spray devices of this character.
