Filed Oct. 20, 1932 Patented June 8, 1937 UNITED STATES 2,083,058 SPRAYING DEVICE Andr de Weal, Chicago, Ill., assignor to Leakproof Sprayer Co., Chicago, Ill., a corporation of Illinois Application October 20, 1932, Serial No. 638,661

4 Claims.

This invention relates to a new and improved spraying device and more particularly to a device for manual operation in connection with a liquid receptacle for spraying liquid contained in the receptacle.

The present device is particularly adapted for use in connection with bottles, cans or other receptacles containing fluid which it is desired to discharge in the form of a spray. Examples'oi l0 such materials are insecticides of various types, lacquers or paints, and polishing fluids to be sprayed on glass, metal or wood. Materials of these types are volatile in character or contain important volatile constituents which should be retained in the material.

Sprayers for similar purposes as developed in the past have comprised a pump to be located in the receptacle and movable pumping members or discharge tubes extending through the 0 cover of the receptacle. These movable members reciprocate throughl the cover and the loosely fitting contact with the cover has been a point of leakage of liquid, as well as a point throughl which evaporation may take place. With such devices it is impractical to ship the container with the pump in place therein, as considerable leakage would take place in transit. It has been customary therefore to provide a separate imperiorate cover for shipping use. This separate cover is an additional expense and further the separate shipment of the pump or spray device necessitates larger cartons and shipping and display packages. Further, a loss of iluid by evaporation or by spilling if the container is upset, will take place after the pump or spray device has been placed in the container for use.-

It is an object of the present invention to provide a new and improved device for spraying liquids.

It is a further object to provide a device of this character adapted to be locked in a receptacle in a manner to prevent leakage from the receptacle. f

It is also an object to provide a construction in which the mechanism may be readily locked against leakage and unlocked for use by a single simple movement.

It is an additional object to provide a device which is simple in design and construction and adapted for commercial production and'use.

Other and further objects will appear as the description proceeds.

I have shown a preferred embodiment of my invention in the accompanying drawing in ,55 which- Figure 1 is an elevation of the device attached to a bottle, and locked against leakage;

FigureZ is a transverse vertical section taken on line 2 2 of Figure 1 on an enlarged scale;

' Figure 3 is a View on an enlarged scale and similar to the upper portion of Figure 2, but showing the device unlocked;

Figure 4 is a horizontal section on an enlarged scale taken on line 4-4 of Figure 2; and

Figure 5 is an enlarged vertical section taken on line 5-5 of Figure 2.

In the drawing the receptacle II has been shown as comprising a glass bottle having the opening I2 surrounded by the neck or flange I3. This angeIS has screwed thereon the cap I4, which also constitutes the base member for the spray pump construction. The guide member I5 is clamped between the cap I4 and flange I3, and the felt washer I6 and bre washer I'I serve to maintain a tight fluid-proof connection. The 20 guide member I5 is provided with the sleeve p ortion I8 which receives-the tubular .plunger I9.V This plunger I9 passes upwardly through the opening 20 in the cap I4. The opening 2D, as best shown in Figure 4, is circular in character except 25 for an enlarged portion 2I, the purpose of which will appear hereafter. i

The plunger I9 carries the collar 22 having the locking lug 23 extending therefrom. Immediately below the collar 22 the plunger I9 carries the 30 rubber packing washer 24. The upper end 25 of this plunger extends laterally and carries a discharge nozzle 26 provided with a small opening 21. Inside of the nozzle 26 is tted a member 28 which is externally screw threaded and serves to assist in atomizing or I'lnely breaking up vthel liquidtobe discharged from the nozzle. The' operating ring 29 extends above the laterally extending portion 25 of the plunger and has its two ends 30 formed to t about the plunger, these ends being retained in place against the plunger by the collar 22.

As shown in Figure 2, the lower end of the plunger I9 carries the piston 3I having the packing 32 and fitting within the pump cylinder 33. The lower end of the cylinder 33 is crimped at 34 to retain in place the valve seat 35 and also to afford clearances for the passage of fluid into the bottom of the pump chamber. The ball valve 36 ts on seat 35 and is retained in place by cage 50 31. This cage or spider 3T is retained in place by the spring 38, the other end of which bears .against the lower face of the piston 3|. v

In assembling the device upon a bottle or other container, the pump cylinder 33 and plunger I9 are introduced into the bottle and the base member or cap I 4 is then secured to the bottle or other container, closing the opening therein. The cap Id retains the guide member I5 in place, the sleeve portion i3 of this guide member serving to guide the reciprocating movement of the plunger in the pumping operation and to maintain it against lateral displacement. 'Ihe parts are normally in the position shown in Figure 3. When it is desired to ship the article or put it away for future use, the plunger and its associated parts are forced downwardly by pressure upon the ring 29. During this downward movement the parts are turned so that the lug 23 passed through the extended portion 2l of the perforation 2li in the cap I4. After the lug 23 is passed below the cap, the plunger is turned to bring the lug 23 to the dotted-line position of` Figure 4. The cap III is provided with the depressed portions 39 to restrain the lug against accidental lateral movement such as tobring it in registration with the extended portion 2| of the opening. When the parts are broughtto the locked position, whichV position is shown in Figures 2, 4 and 5, the rubber packing member 24 is compressed against the upper face of the guide member I5 forming a Huid-tight joint about the` plunger Iii-and between the plunger and the guide member.

To restore the device to operating position it 'is simply necessary to turn thev head of the plunger to bring the lug 23 in registration with opening 2l and as soon as it reaches thisposition thespring 38 will force the plungerupwardly to the position shown in Figure 3. The plunger-may beY reciprocated for pumping without depressing it suiiciently to bring the lug 23 below the level of the top of the cap I4. It will be understood thatV the sprayer is operated by pressing downwardly onY the plunger, which may be done by placing the forenger of the hand-through the ring 29, the bottle being graspedfinY the palm of-the hand. Each downward movement of the plunger will force a fine spray through thel opening 21 in the nozzle Y26. The spring 38 will return the plunger to its upper position so that the operator need merely press down on the ringy repeatedly in order to cause the purnpl and spray to function.

The construction shown is simpleY in design and adapted for commercial manufacture and use. With the parts in the position shown in Figure 2 the assembly is lockedagainst leakage and the pump and receptacle may be packed-in" a small Vcarton and shipped without danger of loss.

` Similarly, if the uid contained inthe receptacle is volatile in-character or contains volatile constituents, Ythe receptacle may be locked against evaporation or spilling of-.the liquidby bringing the parts to locked position.A

While I have shown one preferred embodiment of my invention it is to be understood that it is capable of modification to meet varying requirements and uses and to t it to other types of receptacles. I therefore contemplate such changes and modifications as come within the spirit and scope of the appended claims.
