tions when necessary.
it is an object of this invention, therefore, to provide a simple and efiicient construction of sprayer having a compressed air chamber with means for forcing air thereinto and a valve controlling communication between said chamber and means, which valve is accessible from the outer side of said sprayer.
It is another object of the invention to provide a sprayer having a small discharge tube which is constructed and arranged to be readily removed and cleaned. if necessary.
It is still another object of the invention to provide a sprayer having a liquid receptacle and an air chamber, a spout leading from said air chamber, a discharge tube held in said spout and a nozzle adj ustable in relation to said spout and tube.
These .and other. objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which,
Fig. 1 is a longitudinal central section of the sprayer;
Fig. 2 is a top plan view of the sprayer, certain portions being broken away and others shown in horizontal section;
Fig. 3 is a horizontal section taken on the line 33 of Fig. 1, as indicated by the arrow Fig. 4 is a vertical section taken on line 44 of Fig. 1, as indicated by the arrow;
Fig. 5 is a vertical section taken 011 line 55 of Fig. 3; as indicated by the arrow; and
Fig. 6 is a perspective view of the discharge pipe removed from the sprayer.
Referring to the drawings, a sprayer is shown comprising a liquid receptacle 10. While the receptacle may be made of different shapes, in the embodiment of the invention illustrated, it is shown as substantially cylindrical, the same being so disposed as ordinarily to rest on one longitudinal side. Said receptacle has a filling opening in its top closed by a cap 10a. The receptacle has extending across its top, set thereinto and secured thereto, another smaller cylindrical member 11, the axis of member 11 being disposed at right angles to the axis of receptacle 10. A diaphragm 12 in the form of a flanged circular plate fits within and ex tends transversely of cylinder 11 dividing the same into an air chamber 11?) at the front portion and a pump cylinder 11a at the rear portion. The diaphragm 12 has a central portion provided with a semi-circular groove in which is fitted a cylindrical plug 13. Plug 13 extends through an opening in the side 'of cylinder 11 and has a bore 13a extending from its outer side thereinto. A smaller bore 13?) extends from the bottom of bore 13a through the other end of the plug, and a valve seat is formed at the junction of said bores. A ball 14L is disposed in and movable within bore 13a and adapted to co-operate with said valve seat to close the bore 136, diaphragm 12 and plug 13 having alined openings at 12a communicating with bore 13a. The outer side of bore 13a is closed by a threaded screw or plug 15 threaded in the outer end of plug 13, the outer end of screw or plu 15 being slotted to effect removal thereo The pump cylinder or chamber 11a has a plunger or piston 16 slidable therein secured to a rod 17 extending through the closing member 18 at the rear end of chamber 11a, said member 18 being held in place by screws 19 extending through cylinder 11 and into said member. Cylinder 11 has an opening 116 in the side thereof adjacent member 18. Rod 17 has a handle 20 at its outer end extending transversely thereof. Rod 17 V has a plurality of small lugs 17a struck up therefrom forming stop members adapted to engage a washer 21 at the outer side of member 18 to limit the inward movement of said rod. A washer 22 is also disposed at the inner side of member 18 against which lugs 17?) at the inner end of said rod 17 may engage to limit the outward movement of said ro The front end of cylinder 11 is closed by a rounded cap 110 secured thereto which has an opening in its forward end axially disposed and into which fits and is secured a spout 23 extending outwardly from said cap 110 and having a flange engaging the outer side of said cap. Cylinder 11 has an opening 11d affording communication between air chamber 11?) and receptacle 10 and a tube 24, shown of curved shape, extends through the spout 23 and opening 11d and to a point adjacent the bottom of receptacle 10 so as to be disposed in the liquid in said receptacle. Spout 23 is threaded at its outer end and has threaded thereon a nozzle member 25 having a small central aperture 25a axially alined with spout 23 and the outer end oi? tube 24. Nozzle 25 preferably is knurled on its periphery. A cup-like member 26 surrounds spout 23 having an open front end in which is disposed packing material 27, which bears against the rear end of nozzle 25 and the outer side of spout 28. A compression coiled spring 28 surrounds spout 23 hearing at its rear end against cap 110 and at its forward end against member 27, so that said packing 27 is forced against the nozzle 25 and member The tube 24 has secured adjacent its discharge end a U- shaped clip 29, having spaced cylindrical side portions 29a to frictionally engage the inner side of spout 23, member 29 being somewhat resilient, and the front substantially square.
portion thereof forming a stop.
In operation, material to be sprayed will be placed in receptacle 10 and the parts assembled as shown in Fig. 1. Upon reciprocation of the pump rod 17 air will be drawn into the cylinder 11 into the portion 11a there of and forced through the bore 136 and openings 12a into chamber 111). Air pressure accumulates in chamber 115 and in the receptacle 10. This pressure acting on the liquid 30 in receptacle 10, forces the same upward through tube 24. As the liquid passes from said tube it is met by air forced through the spout 23 and this air and liquid commingle and are sprayed through the opening 25a so that the liquid is broken up into a line mist and discharged in a shower with the air. The character of the shower can be varied by adjustment of nozzle 25. The passage of any liquid around spout 23 is prevented by the packing 27. The packing engaging the nozzle 25 also holds said nozzle in its adjusted position. The tube 24, as shown is curved and if the same should become obstructed it can be removed by removing cap 25 and then withdrawing the tube through spout 23. The
From the above description it is seen that applicant has provided a very simple and efiicient sprayer and one that can be easily and inexpensively made. The valve part is quite accessible and the discharge tube can be easily and quickly removed and cleaned. The adjustable nozzle is easily and quickly adjusted and held in adjusted position.
It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of parts without departing from the scope of the in vention, which, generally stated, consists in the novel parts and combinations of parts disclosed and defined in the appended claims.
What is claimed is:
1. A sprayer having in combination, a liquid receptacle, an air chamber having an opening communicating with said receptacle, a discharge spout extending from said air chamber, a tube extending through said spout and said opening into said receptacle and a clip having spaced outwardly disposed semicylindrical portions fitting in said spout and secured to the discharge end of said tube and frictionally engaging the wall of said spout to hold said tube in proper position therein.
2. A sprayer having in combination a liquid receptacle, an air chamber having an opening communicating with said receptacle, a discharge spout extending from said air chamber, a tube extending through said spout and said opening into said receptacle, and a spring clip of substantially U-shape through which said tube extends and disposed in said spout adjacent the discharge end of said tube and having arms frictionally engaging the wall of said spout to hold said tube in proper position therein.
In testimony whereof I affix my signature.
HENRY E. BRANDT.
