Application March 29,

l2 Claims.

This invention relates to a sprayer construction and particularly to a sprayer ot the type which may be carried by the operator and in which the fluid is placed under pressure by air.

It is desirable in such a sprayer to have a receptacle with a rather large opening .at its top so thatv the spraying uid may be conveniently placed therein. This opening` must be closed during the spraying operation and it is desirable to have a simple means and one which may be easily and quickly operated to tightly close thesaid opening and receptacle. A pump cylinder for pumping air is provided and it is desirable to have the handle which operates the plunger' rod of the pump or pump 'cylinder also used for eifecting said closure.

It is an object of this invention, therefore, to provide a simple and efficient type of receptacle adapted to receive the spraying iiuid.

It is aV further object of the invention to provide a receptacle having a comparatively large opening for the reception of the spraying fluid together with simple and easily and quickly operated means for closing said opening.

It is still another object of the invention to provide a sprayer having an air pump cylinder with a plunger rod equipped with a handle, said handle also being constructed and arranged to be used in effecting the closure of the receptacle.

It is still further .an object of the invention to provide a sprayer comprising a receptacle having an opening at its upper end surrounded by a gasket-receiving surface, a closure plate carrying a gasket adapted to engage said plate and rotatable means for pressing said gasket against said surface without rotating said gasket.

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 similarparts throughout the several views and in whichz o Fig. 1 is a perspective view of the sprayer, a portion of the discharge tube and the discharge nozzle being broken away;

Fig. 7 is a top plan View of the cover clamping plate used; and

Fig. 8 is a top plan View of the container.

Referring to the drawings, a sprayer is shown comprising a receptacleV lil and while various forms oi receptacles might be used, in the embodiment of the invention illustrated the receptacle it is shown as an upright cylinder having beads lila adjacent its tcp and bottom and having a cup-shaped portion iilb at its top. The portion lill; is open at its upper' end and the side wall thereof forms an upstanding rim, the being shown as having an outwardly turned bead lilo at its upper edge. A short distance inwardly of the side wall of portion illb the same is formed with a plurality of partly circular helical flanges ltd, said iianges being partly circular as shown in Fig. 8. The upper part ille of container EEB upon which portion itil) seats and to which it is secured, extends inwardly horizontally and is prof vided with a` central opening lilf of comparatively large diameter, which opening is surrounded by a bead ity struck up from portion ille. A closure plate l l is provided carrying at its central portion a pump cylinder i2 which extends downwardly below said plate into receptacle it and which has its open upper end projecting some distance above said plate, said upper end being provided with an outwardly extending bead ld. The plate H at its outer portionis bent to forni an annular :3,:-

trough in which is seated a gasket member i3. The bead its forms a gasket-receiving surface or a seat for gasket i3 which engages the saine to form a tight closure. A second plate lf2.- is provided, which plate is formed at its outer edge with i a plurality of partly circular helical ilanges lila adapted to cooperate with flanges ld. It will be seen from Figs. 4 and 8 that said ilanges have adjacent ends, the high portion of one flange being adjacent the low portion of the other ange and f disposed some distance'above the same. With this arrangement the flanges lila may have their ends enter below the flanges illd and in the rotation of plate lli the same will be drawn downwardly toward the receptacle by anges ind. Plate ill engages the top of plate le! adjacent the outer top portion of the latter and is adapted to press plate il downwardly as plate irl is rotated. Plate lil has: an upwardly pressed central portion Mb forming a substantially cylindrical recess at its lower side adapted to receive the upper end of the pump cylinder I2. The wall surrounding said recess has circumferentially spaced resilient portions Ific separated a distance slightly less than the diameter of the bead IZa. As shown in Fig. 7 these portions are straight portions at opposite sides of portion I 4b. The bead I2a and thus the upper end of pump cylinder I 2 must be forced past portions Ille with considerable pressure to be received in the recess in portion Mb. The pump cylinder and thus plate II are then connected to plate I against longitudinal separation or movement by any ordinary force but are rotatable relatively to plate It. Said parts may be separated by a longitudinal pull thereon with the application of considerable force. Member it has a central opening through which extends a plunger rod I extending into pump cylinder I2 and which will be provided at its lower end with the usual plunger for the air pump. Rod I5 has a handle I6 secured to its upper end and while this handle might be variously formed, in the embodiment of the invention illustrated it is shown as having upwardly curved sides rectilinear and parallel at their upper portions and connected by horizontal portions Ilia. Portions Ita are also shown as connected by a central portion I 6b having oppositely disposed concave sides. Plate I4 at either side of rod I5 has curved slots Idd, the same having at their centers outwardly extending enlargements Ille. 'Ihe top of portion Mb is also pressed upwardly at portions IM at the ends of said slots and at their outer sides to form small recesses on the underside of said portion. Handle I6 has projecting downwardly from its lower side at each side of rod I5, lugs IIc and these lugs have outwardly extending portions or projections ld with fiat top surfaces. In Fig. 1 the sprayer is shown as having small brackets I'I secured in vertically spaced relation along one side in which are connected the rings I8, in turn pivotally connected to clips I9 secured to the ends of a supporting strap 20 which the operator may place around his shoulders. A portion of the discharge tube 2| for the sprayer is also shown in Fig. l.

In operation, when the sprayer is to receive the spraying fluid, the lugs ,i60 will be placed downwardly through the slots Idd through portions Ille. Handle I5 will then be rotated in a counterclockwise direction and the projections ld will move under the top of portion Mb and said lugs will engage the ends of slots Id and rotate plate ill. Said plate will be rotated to bring the helical flanges Illa out of engagement with the flanges on the top of container IIJ. Handle I6 will then be lifted and at this time the projections iSd will seat in the recesses formed at the undersides of portions IM. Plate I4 and plate II, which, as stated, is connected thereto, will now be lifted and removed together with pump cylinder I2. The spraying fluid can now be poured into opening Ilf When the desired amount of fluid has been placed in the container the plates Il and Irl together with pump cylinder I2 will be again placed in position with gasket I3 engaging the bead IIlg. Handle I6 will now be rotated in a clockwise direction and the lugs IBC will engage the other ends of slots Id and plate I4 will be rotated. The flanges Illa will move under flanges Id and due to the helical formation of these flanges plate I4 will be drawn downwardly toward the container and this plate will press upon plate I I so that plate Il will be moved downwardly and gasket I 3 will be pressed tight against the bead or surface lilo. Owing to the provision `forrelative rotation between the upper end of the pump cylinder and plate It the plate I I need not rotate so that there will be no rotation of gasket I3. This is desirable as it is objectionable to rotate the gasket on its seat. The sprayer is now tightly closed and the desired air pressure can be placed on the liquid by slightly rotating handle I6 so that the lugs IIic can be withdrawn through slots Idd and enlargements Ille and the handle then reciprocated to pump the air through cylinder i2 and into the receptacle I5. After the desired air pressure has been attained the handle I6 can again be moved to insert lugs itc through the slots Md and said lugs may be moved to the ends of said slots. The sprayer can then be carried by means of handle I6 if desired. The member ilb forms in effect a funnel and prevents spilling of any liquid which might not at once enter the opening IElf, The portion Ib being permanently secured to the container is always available and a funnel is always thus in place for use.

From the above description it is seen that applicant has provided a very simple and efcient structure of sprayer and particularly of the closure means for the sprayer. The structure is very compact and comprises very few parts. The filling of the container can be easily and quickly done and the sprayer quickly put in condition for use. lIhe device has been amply demonstrated in actual practice and found to be very successful and efficient.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth in the parts and combinations of parts disclosed and defined in the appended claims.
