AUTOMATC CLEANING DEV'ICE FOR ATOMIZERS Filed April 19, 1928 r I n n l f u g t lnlvento'r John TAZ. ta/fon y ttorng 45 inparts throu hout the several views:

Patented Mar. 31, 1931 @als liberi FMQ' A'/IATEC CLEANING DEVICE EUR ATQ'Z Application filed April i9,

The present invention relates to improvements in atomizers for moistening the air in a factory or room wherein the preferred amount or degree of moisture in the' air is maintained.

The delivery orifices of such humidiiying atomizers are usually small, and at times bef come clogged or stopped with solid particles.

One of the important objects of the present invention i-s to provide a means whereby the delivery or discharge orifice can be readily cleared or cleaned out in the event of stopave. p further object is to provide a cleaning device for atomizers whichv will be entirely automatic in its operation, thus saving considerable time and labor, the cleaning device l being further at all times positive and eihcient in its operation.

A further object is to provide an automatic cleaning device for atomizers wherein the cleaning wire normally projects throughthe discharge orice or nozzle, a spring ressed head being operatively connected with the cleaning wire so that air under pressure entering the atomizer for ccmmingling with f blc and further well adapted tot the water will force the spring pressed head inwardly to maintain the cleaning wire in an inoperative position, the wire being automatically moved to an operative position when the air pressure or supply is cu-t od to the atomizer. 4

A further object is to provide an auto` -matic cleaning device for atomizers vof the above mentioned character which is simple in construction, inexpensive, stron and durae purpose for which it is designed.

Otlier objects and advantages of the invention will become apparent from the following description when taken in connection with the accompanying drawings. In the accompanying drawmgs wherein like reference characters indicate correspondlgure 1 is a ottom plan view ofanother for of atomizer havin my automatlc cleanin device associated t erewith, and

cap 40 and the 1923. Serial No. 271,22?.

- Referring to the drawings there is shown an embodiment of the atomizer wherein the same includes a .horizontally disposed vair chamber 31 that is open at its respective ends, the central portion of this air chamber being formed with a compressed air inlet 32.

Arranged within the forward end of the compressed air chamber 31 is the water chamber 33, that is closed at its inner end, the forward end thereof being formed with a threaded opening to receive the threaded portion of a conical discharge nozzle 34, and which nozzle terminatesin the discharge tube 35. A water inlet pipe 36 extends .laterally l from the bottom of the inner end portion of the water chamber for communication to any suitable source of water supply.

The cap 37 is ydctachably secured on the forward end of the air chamber 31 and is spaced with respect tothe forward portion of the water chamber 33. The forward end portion of this cap 37 is of conical formation, as illustrated at 38 and terminates in a circles the water discharge tube 35 formed on the forward end of the nozzle 34.

l A cap 40 is removably secured on the open rear end of the air chamber 31 and this. cap is formed with acentral air vent 41. A partition 4Q-is provided in the .rear end of the air chamber 3l whereby to cooperate with the` cap 40 to form a cylinder 43 and -this cylinder has communication with the air restricted air discharge nozzle 39 that enchamber at 44 in Figure 4. A plunger45 u is arranged for reciprocatory movement in the cylinder 43 and an pxpansible coil spring 46 is 'arranged for disposition between the plunger for normally hold ing the plunger in"forwardmost position in the cylinder. l A

A cleaning rod orwire47 is secured at its discharge tube 35 and normally the spring rear or innerend tothe plunger 45 and exprojects through the nozzle v34 and the vwater will cause the forward end ofthe cleaner rod to be extended through the tube.

When air under pressure is admitted to the chamber 31, a certain amount of the air will enter the cylinder 43 to force the plunger 45 rearwardly, compressing the spring 46 and simultaneously moving the cleaning rod 47 rearwardly out of engagement with the tube v 35 so that the water entering the chamber 33 through the inlet 36 will be free to be forced through the discharge nozzle and the tube Where the same is commingled with-the airA discharged from the nozzle 39.

As soon as the air pressure is released, the spring 46 will return the plunger 45 and the cleaner rod 47 to the position shown in Figure 4 thus removing any obstruction that may accidentally lodge in the tube 35. It will thus be seen from the foregoing description that I have provided an automatic cleaning device for association with atomizers for compressed air humidiers used in mills, lants and the like for humidifyin the air an by reason of its simplicity, the c eanirfi device will at all times be positive and e cient in its operation as well as automatic,

thus saving considerable time and labor and Y expense. a

A cleaning device of the above mentioned character can also be readily and easily associated withvarious t es of atomizers without requiring mucha terations to the parts of the atomizer with which the cleaning device is to be associated.

The -automatic cleaning device can be equally aswell used on other spraying devices where a iluid under pressure is employed.

While I have shown the preferred embodiment of my invention, that minor changes in the size, shape and arrangement of parte may `be resorted to without `de arting'from the spirit of the invention and) th'e scope of the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is lAn atomizer comprising a sectional casingv consisting of a centrally disposed tubular section open at its opposite ends and having a central air inlet, 'a slidable pressure responsive piston in one end of the tubular section,

a removable cap section closing the piston end of the central section, a border chamber disposed longitudinally of the opposite end of thesaid central section and spaced circumferentially from the enclosing wall of said section with its outlet end disposed outwardly of the end of the said section and hav1ng a lateral inlet conduit at its inner end formed integral with and projectin exteriorly ofthe central section, a jet noz e at the outlet end of said water chamber, a removable nozzle section at 4the nozzle end of said central 65 sectionl having a cylindrical portion suritis to be understood rounding the said outwardly disposed outlet Y end of t e water chamber, and a conical portion terminating' in a restricted nozzle encircling the said jet nozzle of the s'aid chamber, a rod secured at one end to said piston and havin its other end disposed in the said jet nozzle 1n line with the spray orifice thereof anda spring between the said piston and the said removable ,top section, said spring being tensioned to pressagainst said piston for normally holding said pin in the spray orifice of the said nozzle.

In testimony whereof I aiiix my signature.

JOHN JACKSON.
