OIL-PURIFYING Armna'rns.

To all whom it may concern Be it. known that I, EDWIN BaUM, a citizen of the United States, residing at Keo 'kuk, the county of Lee and State of Iowa,

have invented certain new and useful Improvements in. Oil-Purifying Apparatus, of

' which the following is a specification.

My invention relates to improvements in,

apparatus for purifying oil by removing the water contained therein.

An important object of my invention is to provide apparatus of the above mentioned character, which is simple in construction, inexpensive to manufacture, and willoperate expeditiously and continuously.

Other objects and advantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of thisspecification, the figure is a central longitu' inal section through the entire apparatus.

In the drawings, wherein is illustrated apreferred embodiment of my invention, the

numeral 1 designates a preferably cylindri- -cal vertical main shell or casing, having its lower end permanently closed and its upper end normally closed by a removable lid or cover 2, equipped with handles 3. The lid or cover 2 is provided centrally thereof with an opening 4, through which passes a vertical feed pipe 5, the lower end of which passes through a. double walled conical heatin chamber shell 6, and is rigidly detachably connected therewith by means of rings 7 and 8 disposed above and below the same. Attention is called to the fact that the feed a pipe 5 discharges into the upper end of the ing an upwardly extending annular flange 12, forming an annular catchment receptacle or trough 13. The double walled heating chamber or shell 6 is supported by a suitable number of tubular legs 14, apertured near their lower ends, as shown at 15. The

lower ends of these legs engage the bottom of the main shell or casing 1 while the upper walled conical shell 6, with their upper ends' ends thereof pass through apertures 16 formed through the walls of the double Specification of Letters Pat ent-L I Paten ed Sept. 1, 1914 Application filed November 13, 1913. serial n6.=soo,so5.

in free communication with the annular ing rings17 arecarried by these tubular legs and engage the lower wall of the shell '6, whereby the legs are rigidly connected therewith. The tubular legs l4'have no communlcation with the dead air space 10 of the double walled shell (3, such shell being hermetically sealed.

- The numeral 18 designates a conical steam heating coil, which increases in diameter downwar ly, and is arranged within the conical heating chamber 9, in spaced relation to the lower wall of the shell 6, as shown. Steam is suppliedinto the lower end of the coil 18 through a pipe 19 and passes out of the same through a pipe 20. The opening of the upper-most turn of the coil 18 is arranged below, spaced from, and in alinem'ent with the discharge end of the feed pip'e'o, whereby oil passing from this pipe will circulate inwardly of, through, and

about the heating coil 18,'in direct contact therewith upon first entering the heating chamber.

The minimal-21 designates a supply receptacle or hopper, having its upper end nor mally closed by'aremovable lid or cover 22, equippedwit-h handles 23. This lid or cover is provided with a feed opening 24. The supply receptacle*or hopper 21 has its bottom 25 formed conical; decreasing'in diameter downw'ardlyand provided at its reduced end with a tip or pipe section 26, extending into the upper end of the feed pipe 5, and preferablyhaving screw-threaded engagexnent therewith, as shown at 27. Arranged within thesuppl-y receptacle or hopper21 is a conical strainer 28, increasing in diameter downwardly, and having its ,enlarged end or base arranged upon the bottomf25'of the receptacle or hopper 21, as shown.

The numeral 29 "designates an oil outlet pipe, connected with the main shell or casingl, near and spacedfrom the upper end .thereof, as shownJ'This oil outletpipe communicates witli'ianiinterior oil outlet h'oppcr 30, haymgfits'upper enlarged end31 formed entirely open, as shown. Arranged preferably diametrically opposite the oil outlet pipe 29 is a wateroutlet pipe-32, the inner end of which is in-=communication with a closed casing or box 33, arranged nearthe lid or cover 2, as shown. Extending into this casing or box 33 is a vertical' water outlet pipe 34, held in place by brackets 35. The lower end of the pipe 3 1 is provided with a flaring in-take mouth 36, disposed near and spaced from the bottom of the main shell or casing 1, as shown.

The numeral 37 designates a vertical tube gage, connected with the main shell or casing 1, in the usual manner, to indicate the level of the liquid therein. The main shell or casing 1 is provided adjacent its bottom with a drain pipe 38, which is equipped with a suitable cut-off valve (not shown}.

The operation of the apparatus 1s as follows: The oil having the water mixed therewith is fed into the receptacle or hopper 21, and passes through the [conical strainer 28, whereby any soiled material of considerable s1ze is prevented from passing into the main shell or casing 1. This oil now passes into the feed pipe 5, and gravitates through the same to be discharged from the lower end thereof, into the heating chamber 9. In this heating chamber the oil containing the water passes through, about,'and in direct contact with the heating coil 18, whereby the oil is heated to a temperature at which it will separate from the water. The water condenses and moves to the bottom of the main shell or casing 1, while the oil circulates around the free edges of the double walled shell 6 and passes into the upper portion of the main shell or casing. The heated oil in the upper portion of the main shell or casing tends to circulate therein, passing upwardly adjacent the shell 1 and downwardly adjacent the double walled shell 6, as indicated by the arrows, while the entire body of the purified oil is rising. The function of providing the double walled heating chamber or shell 6 with the dead air space is to provide means for retaining the heat, as far as possible, within the heating chamher 9, wherein it is desired to heat the oil while the same is in the lower portion of the main shell or casing, to separate the same from the water. However, it has been found that all of the water may not be separated from the oil'while in the heating chamber 9,

the remainder of the Water being separated from the heated oil after thesame passes into the upper portion of the main shell or casing 1, adjacent the double walled shell 6,

. asabove explained. hen the oil separates from the water, above and adjacent the double walled shell 6, such water is collected in the catchment receptacle or trough 13,

, and passes downwardly through the tubular legs 14:, to be discharged through apertures 15 onto the bottom of the main shell or casing 1. When the level of the oil and water in the main shell or casing 1 reaches a certain height the oil passes into the hopper 30 and is discharged through the pipe 29, while the water passes from the bottom of the main shell or casing 1, through pipe 34, closed boxes or casing 33, and through pipe 32. Any sediment collecting in the bottom of the main shell or casing may be removed through the opening 38.

A particular advantage gained in my construction is the ease with which the several parts of the apparatus may be separated and assembled, for the purpose of cleaning or repair. It 1s obvious that the supply receptacle or ho per 21 may be readily disconnected from t e feed pipe 5, whereby the lid or cover 2 may be removed, and the double walled shell 6 and associated elements taken out of the main shell or casing 1.

It is to, be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having described my invention, I claim 1. In apparatus of the character described, the combination with a .main casing, of a shell arranged therein for forming a heating chamber therebelow and provided with an upstanding flangeforming a catchment receptacle for the water separated from the oil, depending tubes connected with the shell and having communication with the catch ment receptacle, a heating coil arranged within the heating chamber, and a feed pipe discharging into the heating chamber.

2. In apparatus of the character described, the combination with a main casing, of a conical double walled shell arranged therein and inc'reasin in diameter downwardly for providing a eating chamber open at its lower end, a continuous flange formed upon the upper side of the conical shell for providing a catchment receptacle, tubular legs connected with the double walled shell, engaging the bottom of he main casing, and aperture'd near their ower ends, a feed pipe leading into the heating chamber, and a heating coil arranged within the heating chamber.

In testimony whereof I aifix my signature in presence of two witnesses.

EDWIN P. BAUM.
