, GEORGE FRANKLIN wENTz, OF ST. LOUIS, MISSOURI. y l`Dl'sTll- LlNvc-i` A|= PARATUS.l i l Specication of Letters Patent.

Application led January 27, 1904. Serial No. 190,832.

To aZwh/om t may concern;

' Be it known that I, GEORGE FRANKLIN 'WENTZ, a citizen of the United States, residf d istilling apparatus, especially of that type employed inthe distillation of water, though perhaps useful for other analogous purposes.

The present invention relates more particularly to improvements in the steam-generator, its construction, means ofsupport,

and themeans of supplying water thereto.

One of the features resides in mechanism which will permit the attachment of the genv erator to and its support upon a rsteam-boiler,

where it may be properly associated with the other elements' that go to` make up the distl-r.

ling apparatus as a whole. y

Another feature relates to novel automatic means for supplying water to thegenerator so that the said Water will eect the auto-l matic cleansing of the same.

Still another feature is the construction, arrangement, and combination of theelements that constitute the generator as a whole, whereby a desirable and effectual manner of heating the water is obtained and .3.0

all the parts are accessible forthe purpose of repair, renewal, or adjustment.

n the drawings accompanying this specification, Figure 1 is a side elevation of the improved distilling apparatus. Fig. 2 is a vertical sectional view, on an enlarged scale, through the generator. Fig. 3 is a detail horizontal sectional view through a portion of the same. Fig. 4 is a side elevation of the oat employed, and Fig. 5 is a detail sectional view taken on the line 5 5 of` Fig. 3. Y I

Similar reference-numerals indicate corresponding parts in all the igures of the draw- Ings.

The'distilling apparatus is associated with an ordinary stand-boiler, (designated, 5,) alongside the lower portion of which is arranged a condenser-tank 6. A water-inlet pipe 7 has a branch connection 7 a through a coupling 7b with the lower portion of the reservoir or boiler 5, and said pipe leads, as shown at 7 C, to the bottom of the tank 6, and a Water-outlet pipe 8 extends from the topof the tank 6 and is in communication with the top of the reservoir or boiler 5.' Brackets 9 are located against one side of the boiler and are secured thereto by a clamping-band 10, which surfices 28 in their upper sides. y heater is connected with any suitable-source 'of gas-supply-as, forinstance, by a tube 29,l

thecasing a slight distance, constituting an annular rib or bead 15, that forms a seat for the annular cylindrical wall 16 of the caslng. This casing-wall'l carries at its upper end a conical top 17, having a central o penmg 1S, surrounded by a bead 19. Within the casing is located the generator roper, which 1s in the form of a cylindrica receptacle 20,

. spacedfrom the walls of the casing to form an annular ilue 21; The bottom 22 oiv this receptacle inclines downwardly to a centrallydisposed depending sediment-trap tube 23, which tube extends through the central opening 14:y of the casing-bottom 12 and 1s provided With a suitable turning valve 24. The top of the casing is in the form of a truncated cone 25, disposed substantially parallel to the top 17 of the casing, but spaced threfrom, as shown. The receptacle'is suspended within Patented March 20, 1806.

l rounds said boiler. The horizontal arms of the casing by means lof suitable boltsor rivets 26, connecting the tops 17 and 25. As will. be seen by reference to FIg. 2, lthere 1s considerable space between the bottom of the receptacle and the bottom of the casmg, this space aording sufiicient room for a suitable burner, shown in the presence instance in the form of a -pair of concentric-ring tubes -27 surrounding the sediment-trap and having orlattached to an adjacent gas bracket 30. (Shown in Fig. 1.)

The top 25 is providedwlth a comparatively large centrally-dlsposedhand-opening 31, surrounded by anupstandmg exteriorlythreaded boss 32. `Said hand-Opening 1s normally closed, however, by means of a {langecap 33, screwed upon the vboss and having a hand-wheel 34, by means of which it may be readily operated. This cap 1s also provided This burner or lCO IOS

with an annular internal flange 35, arranged to fit Within the boss 32`and constituting means for holding suitable packlng, as 36,

which prevents the escape of steam through this joint. The cap is furthermore provided with a centrally-disposed upstanding nipple 37, to which is coupled, by means of a sleeve 38, one end of a steami e 39, said steampipe being of considerably ess diameter than the diameter of the hand opening. The

-steam-pipe 39 extends through the condenser-tank 6 and terminates in a water-discharge pipe 40, which may be introduced into a suitable receiving vessel 4l. An air purier and mixer 42 is located in the pipe 39.

Means are employed for automatically supplying water to the generator. As illustrated in Fig. 1, a water-supply pipe 43 leads from the outlet-pipe 8 between the condenser-tank and the reservoir or boiler 5 to the lower portion of the generator-receptacle 20. The passage-way through this pipe can be closed by means of a turning valve 44, Fig. l, so that, if desired, the supply of water can be entirely cut off. An automatically-operated valve is also provided for this purpose and is fully illustrated in Fig. 2. The pipe 43 terminates in a horizontally-disposed nozzle, (designated as a whole by the reference-numeral 45,) the inner end of which is in the form of a cap or head 45a, that projects into the receptacle 22. This nozzle contains a valve-seat 46, with which coacts a valve 47, arranged within the nozzle. The valve op ens against the pressure of the water, and one end thereof coacts with the valve-seat, the opposite end, or, in other words, that opposed to the How of the water, being made conical, as shown at 48, for the purpose of offering as little resistance as possible to such How. The valve carries a stem 49, that projects beyond the inner end of the nozzle into the receptacle, where it is pivoted, as shown at 50, to the depending short arm of a bellcrank lever, that is pivoted to a bracket 52, forming a part of the inner end of said nozzle.` Another arm 53 of this bell-crank lever extends transversely of the receptacle, and on its free end is mounted a cylindrical iioat 54. An ear 55 is attached to this float and is adjustably mounted on the arm 53, being normally held against movement, however, by a set-screw 56. On the outer end of the arm 53 are secured suitable counterweights 57, held in place by a cotter or split key 5S. Itis to be noted by reference to Figs. 2, 3, and 5 that the inner end of' the nozzle is closed with the exception of the small opening in the cap or head, through which the valve-stem 49 extends and iits as snugly as is desirable to prevent the passage of water thereto, such passage, moreover, being prohibited by a washer 59, locatedupon the stem and movable into engagement with the end wall of the nozzle when the float is depressed. The outlet for the water is through a lateral discharge-oriice 60, that extends in a plane perpendicular to the stem and is inclined downwardly, so as to form an angle with the horizontal and with the bottom 22, which orifice thus projects the water downwardly against the bottom 22 ol' the receptacle and at an inclination to said bottom for the purpose hereinafter pointed out.

The operation of the apparatus isas follows: Assuming that the boiler or reservoir 5 is supplied with water under pressure, it will be evident that the condenser-tank 6 will likewise be iilled and that water flowing through the supply-pipe 43 will enter the generator-receptacle 20 until the iioat 34 rises sufficiently to close the valve 47. lf heat is now applied to the receptacle `from the burner, the water therein will be heated and brought to a boil. Particular attention is invited to Fig. 2, which shows the circulation of such water. Instead of an outward circulation, as is ordinarily the case with a receptacle, the heat being supplied not only to the bottom, but to the sides, will cause an upward and inward circulation at said sides and a downward circulation at the center. The effect is that the sediment will to a great extent be deposited at the center, and thus `lind its way into the sedimenttrap 23. The steam generated will of course iind its way through the pipe 39 and be condensed within the tank 6, the condensed water iinding an outlet into the vessel 41. This condensation of the steam will of course heat the water in the tank 6, which will enter the top of the boiler or reservoir 5. As the level of the water within the generator-receptacle falls, due to the carrying ofi' of the steam, the iioat will fall with it, and consequently a fresh supply ci" water will be introduced through the supply-pipe 43. Now, as this supply-pipe is connected with the outletpipe 8 for the heated water, vit will be evident that heated water will be furnished to the steam-generator. Moreover, this water will be projected downwardly and at an inclination against the bottom 22 of the receptacle, causing a gyratory movement of the body of water within the receptacle, which movement thoroughly cleanses and scours the bottom and gradually works the sediment deposited thereon to the trap 23, whence it may be drawn. Thus to thoroughly cleanse the receptacle, it is only necessary to open the valve ci the sediment-trap and permit the water to llow therefrom for some time. When said trap 24 is opened, the water contained in the receptacle of course passes out through said trap, and the loat, sinking with the level oi the water, opens the valve 47 to its fullest extent. The washer 59, secured to the outer end of the valve-stem 49, thereupon abuts against the end 45 of the nozzle, consequently closing the opening therethrough, and thus securing the full force of the escaping water through the oriiice 60. This washer, furthermore, constitutes a stop that limits the downward movement of the i'loat and arm in order to IOO IOS


. prevent its striking the bottom of the receptacle.

It will be evident that this arrangement has many advantages, as it secures puriiied water practically Without the necessity ofthe attention of an operator. The supply of water to the generator being automatic, there is no danger of burning outthe elements, and this automatic supply practically constitutes the means for keeping the generator in a sanitary condition; The entire structure can be readily supported upon an ordinary standboiler and attached to any convenient source of gas-supply. Moreover', access can be readily gained to any or all of the arts. The casing is so constructed that the urner may be readily reached, and by removing the cap l33 the hand maybe passed into the receptacle and by disassociating the parts therein the float and valve connections may be easily.'


From the foregoing it is thought that the construction, operation, and many' advan- 'tages .of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size,

shape, proportion, and minor details of construction may beresort'ed to without de arting from 4the spirit or sacrificing any o the advantages of the invention.` f
