2 Claims.
This invention relates to spraying mechanism and more particularly to mechanism of the character whereby liquid may be forced under pressure and discharged, and admixture of air combined as desired. An object of the invention resides in the provision of mechanism in which liquid is forced by air pressure through a discharging nozzle, utilizing a head of pressure upon the body of the liquid and providing for utilizing such air as a mixing agentJ with the discharged liquid. More particularly, an object of the invention is the provision of a device comprising a liquid containing receptacle and an air pump inY association therewith, whereby air under pressure causes discharge of the liquid through a discharging nozzle and such compressed air may also be utilized as a mixing agent with the discharged liquid. A further specific object resides in providing a device in which the air pressure utilized to discharge the liquid is so conveyed and distributed as to set up an agitation in the liquid, which is particularly advantageous when using spraying compounds or other materials requiring constant or periodical agitation to maintain a uniform con- 23 dition of the contents.
Other objects will appear hereinafter.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and, in which:
Fig. 1 is a vertical sectional view of a device embodying the features of the invention;
Fig. 2 is a sectional View taken substantially on the line 2 2 of Fig. 1;
Fig. 3 is a vertical sectional View taken substantially on the line 3 3 of Fig. 2;
Fig. 4 is a vertical sectional View taken sub- 40 stantially on the line 4 4 of Fig. 2;
v Fig. 5 is a horizontal sectional view taken substantially on the line 5 5 of Fig. 1; and
Fig. 6 is a detail view, partly in elevation and partly in section, of the discharging nozzle.
As illustrated in the drawings, the preferred embodiment of the mechanism includes a liquid containing receptacle 9, an air compression cylinder l0 and an intermediate housing 1l. Housing 1l may be provided with a flange 12 adapted to be bolted to a complementary flange 13 upon the receptacle or tank 9, and the latter is otherwise preferably hermetically sealed. Similarly, cylinder l0 may be suitably bolted to the intermediate housing 11, as shown in Fig. 1. Mounted for reciprocation within cylinder 10 is a piston 1930. SerialY N0. 438,005 (Cl. 299-89) or plunger 14 secured to piston rod 15 which extends upwardly through the cylinder 10 and is secured to a connecting member 16 pivoted to operating handle 17. Handle 17 may be conveniently connected for manual operation by a link 18 pivoted to the device at 19. The intermediate housing 11 is preferably divided into three; vertical circular chambers, a relatively large chamber 20, a smaller chamber 21 and a second smaller chamber 22. Chamber does not communicate with the pump chamber 23, but a tubular member 24 is preferably threaded in the portion constituting the chamber 20 and extends to a point adjacent the bottom of tank 9, as shown in Fig. 1. A liquid discharge tube 25 is also connectedto communicate with chamber 20, as shown inV Fig. 3. Chamber 22 does'not communicate with pump chamber 23 but communicates with the interior of tank 9 by means of duct 26, and an air discharge tube 27 also is connected to the portion constituting chamber 22, as shown in Fig. 4.
Chamber 21 communicates with pump chamber 23 by means of a check valve 28 normally held seated by compression spring 29, as shown in Fig. 3, and connected to the portion constituting this chamber is a depending air pipe 30 connected at the lower end with a circular pipe 31, as shown in Fig. 5. Pipe 31 is preferably provided with a plurality of uniformly spaced perforations 32 for the purpose of permitting a uniform discharge of air adjacent the bottom of tank 9 whereby the air will pass upwardly through liquid 33, as shown in Fig. l.
A manually operated valve 34 is provided in air tube 27 adjacent chamber 22, and liquid tube 25 and air tube 27 terminate in a discharge nozzle 35. As shown in Fig. 6, the connections of tubes 25 and 27 converge within nozzle 35, but the respective liquid and air ducts are provided with manually operated valves 36 and 37, respectively, whereby the flow and admixture of liquid and air may be regulated. A ball check valve 38 is provided in a chamber 39 communieating with the cylinder chamber 23 and the exterior of the device. This valve is for the purpose of allowing air to be drawn within the cylinder chamber 23 upon the upstroke of piston 14 but closes upon the downstrolre. The reverse action takes place on check valve 28 which opens on the downstroke of piston 14 and closes on the upstroke. There is provided a compression chamber 40 in the upper portion of tank 9 above the liquid 33.
When rectilinear motion is set upl in the piston 14, air is forced downwardly through pipe 30 and expelled through perforations 32 in circular pipe 31 disposed adjacent the bottom of tank 9. This expelling of air causes the liquid 33 to be agitated and the liquid or liquid compound is stirred as the air passes upwardly therethrough. Thereafter a pressure is set up in the chamber 40, which forces liquid upwardly through tubular member 24 within chamber 20 and outwardly through the liquid discharge tube 25. When it is desired to cause a mixture of air with the liquid for spraying purposes, valve 34 may be opened and properly adjusted. A further adjustment of the liquid and air mixture is furnished by valves 36 and 37.
While I have illustrated and described the preferred form of construction for carrying my invention into eect, this is capable of variation and modication without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modications as come within the scope of the appended claims.
What I claim as new and desire to secure by Letters Patent is:
1. A device of the class described, comprising a liquid containing receptacle having an annularly flanged opening at the top thereof, a housing having a ilanged end portion Afor attachement to the flange of said receptacle, said housing being provided with a liquid outlet chamber, a tubular member connected to said outlet chamber and extending downwardly within liquid in said receptacle, said housing being provided with an air inlet chamber, a tubular member connected to said air inlet chamber and extending downwardly parallel with and adjacent to said rst mentioned tubular member within liquid in said receptacle, a perforated air distributor at the lower end of said second mentioned tubular member and disposed within liquid in said receptacle near the bottom thereof, said housing being provided with an air outlet chamber communicating with said receptacle, a discharge nozzle connected to said liquid outlet chamber and said air outlet chamber, respectively, by separate valvecontrolled pipes, and an air pump communicating with said air inlet chamber, said pump being detachably secured on the upper end portion of said housing.
2. A portable device of the class described,
comprising a cylindrical liquid containing tank normally resting on its end, said tank having a central opening in its upper end, a generally cylindrical housing having provision for detachable liquid-tight attachment to the opening in the top of sadtank, a pump detachably secured to the upper end of said housing, said housing constituting in effect a restricted necked connection between said tank and said pump, said housing having an air inlet chamber communicably connected with said pump, a tubular member communicably connected at its upper end to said air inlet chamber and projecting downwardly into liquid in said tank and terminating communicably near the bottom of the tank, said housing having therein a liquid outlet chamber,- a second tubular member communicably connected at its upper end with said liquid outlet chamber and extending downwardly within liquid in the tank and terminating communicably near the bottom of the tank, said housing having therein an air outlet chamber in communication with said tank, a discharge nozzle, a manual valve controlled communicable pipe connection between said nozzle and said liquid outlet chamber, and a separate manual valve controlled communicable pipe connection between said nozzle and said air outlet chamber.
