10 Claims.

The' main objects of this invention aref First, to provide a sprayer adapted to receive receptacles of diierent capacities, thereby permitting the receptacle to be merchandised as a unit, and avoiding the necessity of providing a complete sprayer for each size or capacity receptacle.

Second, to provide a sprayer which is very compact when disassembled from the receptacle for shipping or storage.

Third, to provide a sprayer having these advantages which is economical to produce and very strong and durable and convenient to use.

Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined in the claims.

A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a fragmentary side elevation of a sprayer embodying the features of my invention, a receptacle of one capacity being shown by full lines, a larger receptacle being indicated by dotted lines.

Fig. 2 is an enlarged fragmentary view in longitudinal central section on line 2-2 of Figs. 3 and 7.

Fig. 3 is an enlarged fragmentary view in section on line 3--3 of Figs. 1 and 7.

Fig. 4 is a perspective view of a liquid tube which constitutes in operation a part of the atomizing tube.

Fig. 5 is a sectional View through one type of receptacle with its closure and illustrating the arrangement of the liquid tube therein.

Fig. 6 is a fragmentary side elevation of the pump with the parts that are fixed thereto.

Fig. '7 is an enlarged fragmentary vertical view of the pump.

Fig. 8 is a perspective view of another receptacle illustrating the relation of the liquid tube therein, the tube being shown by dotted lines.

Referring to the drawings, 1 represents the barrel or cylinder of an air pump, 2 the piston, 3 the piston rod and 4 the handle thereof.

The cylinder is provided with a head 5 arranged in spaced relation to the front end 'of the cylinder and having an air discharge opening 6 therein. An annular drip cup wall 7 is secured to the end of the cylinder and coacts with the head in the cylinder wall to provide a drip cup 8.

The atomizing tube 9 is secured to the cylinder head to depend through an opening 10 formed in the wall of the cylinder and through the cap 11 secured to the underside of the cylinder below the drip cup. This cap is internally threaded` to receive the threaded neck l2 of a receptacle 13. The cap is nxedly secured, solder being 6W employed in the embodiment illustrated.

The receptacle is provided with a threaded closure 14, this closure being removed when the receptacle is attached to the pump. The receptacle is provided with a liquid tube 15 which 65 depends therein to a point adjacent the bottom of the receptacle, this liquid tube being adapted to receive the lower end of the atomizing tube when the receptacle is assembled on the pump and constitutes an extension thereof, as clearly 7@ shown in Figs. 2 and 3 of the drawings.

The tube 15 is provided with a disk-like head 16 adapted to receive the neck of the receptacle and to receive the cap on the receptacle or the closure 14 as clearly shown in Figs. 2, 3 and 5.

Outer and

inner gaskets

17 and 18 are preferably arranged between the tube head 16 and the cap 11, the inner gasket 13 being arranged upon and supported by the atomizing tube.

A gasket 19 is preferably provided between 89 the tube head 16 and the end of the neck. Drop openings 20 are formed in the cap which is preferably struck up at 21 to provide a recess 22 for the seam 23 of the pump barrel, see Fig. 3, the openings 20 being formed during this operation. The head 16 is provided with a drip opening 24 so that liquid collected in the drip cup can drain into the receptacle.

In Fig. 1, I illustrate two sizes of receptacles. Fig. 8 illustrates another type of receptacle 25.

With this arrangement of parts, the receptacles can be furnished as complete units so that the merchant is not required to stock a complete spra cr for the various sizes of sprays which are in demand, and the customer having acquired the pump portion of the sprayercan secure the spray as desired, and it is not necessary to pour the liquid from the receptacle into which it is secured into the spraying receptacle which is frequently annoying and results in spilling, or the necessity for using a funnel and the cleaning. The pump, when the receptacle is removed, is quite compact and does not have the long projecting atomizing tube as is commonly present.

I have illustrated and described my improvements in an embodiment which I have found very practical. I have not attempted to illustrate or describe certain adaptations and embodiments which I contemplate as it is believed that this disclosure will enable those skilled in the art to em- 1,10

body or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
