.THE lEX'I'B-KCTION 0F 1 o allauhnmit'muzymm: v

Be it known that we, iERHRAIlM'G. SMITH and Annunzr *Wrmauousn, citizens of the United States, and'residents of Pearl City,

county of .Honolulu, Territory of Hawaii,-

' ciated when the beeswax is extracted from honeyco1nbs,.and the ohjectzof the invention is to provide .an improved apparatus for producing .a circulation of hot water between the container in which-.theimate'rial to be treated .is zplaced, and in which the impurities are retained, and the receiver or trap .into which the pure wax, entrained by the circulating water, is discharged.

More \particularly, the invention .is 'designed to avoid the useof a separate water heater andto efiect-the circulation of hot water byapplying heatto the container, said 'container being connected with the receiver taining the pure wax, so thatsuc'h water will be conducted into the receiver and an; effective circulation throughout the entire.

apparatus maintained. The container is rovided with a screen of any appropriate ind to retain the impurities, and the wax floating on the surfaceof the water in the trap or receiver can be drawn oil by means of a suitable valve or in any other con- 1 venient way.

In the accompanying draWing:-Figure 1 is a slde elevat on of an apparatus constructed in accordance with the invention.

Fig. 2 is a vertical longitudinal section through the apparatus.

In the drawing,the container into which the wax containing material is introduced is indicated at 5, and the receiver or trap 1ieciflca'tion ofi'LettersfPateat. y gfe t Aug, n pumum-aiemmmnas, mo. [Serial na-auaaev.

that serves .as .a separator for :the ;.pure Wax is indicated .atifi. 'llhe container 5 .may .be of may appropriate form, but -we find .it advisable to construct .athe cover .7 in :the shape iofzan arch, and said cover, which is freely removable 'iirom the bodyofihe conta1ner,;may.-be locked on said -ih ody by means of locking devices 8 of any suitable. character. interposed hetweenthe body of the container .and the cover is :a screen .5 which may he removedwhenthecover is taken off, in order 'it-hat the :wax .co'ntaining material may be deposited in :the container. The container is heated inany convenient way, as .by the gasburner ;9 located beneath the bottom of sthezsa-me, such gas burner being illustrated merely by .way of example.

Leading upward from the-arched cover 7 osflthecontainer .is an upright pipe 10,-which isoonnected tothecover at the center ofthe latter,.and said pipe extends above the container to a relatively considerable distance. Intermediate of the endsof said .pipe. the same connected by means of a union 11 with azbranch pipe .12 which leads into-the upper part of the receiver or separator 6.

The pipe :12 is secured to the receiver bymeans of a swivel connection .12 .in order to :permit .the raising of the cover of the container. Theylower part of the separator is-connected with:the lower part ofthecontainer.by,.means of :a pipe 13 controlled by a valve 14. In the embodiment illustrated,

the separator-6 consists merely of a cylindrical vessel provided with a sight window 15 -by :means of which the level of the liquid therein can be observed. A drawotf valve .16 is placed "in the wall of the .in the container. The screen and cover are then replaced and-water is poured into the receiver 6 until it is at about the level indicated in Fig. 1, such level bein easily visible through the window 15. fie container 5 is then subjected to heat by means of the heating device 9, with the result that receiver at a point midway of the height of if the valve 14 the connecting pipe 13 is open a continuous circulation of water will be produced betweenthe container and recover. The water in the container is brought to a boil to theend that the wax in the mass will be melted, after which suchwax is carried upward through the pipe 10 by the circulating water, the impurities being retained in the container because of their inability to pass through the screen 5,

' as will be understood. The boiling of the 01f to the receiver'through the uppe necting pipe 12. At the same time, the

water in the container will cause bubbles and steamto pass upward through the pipe 10 and these will produce an eifective upward pumping action on the water that enters the lower end of the pipe 10, whereupon such water will beraised and carried r conwater will circulate downward in the receiver or separator and-the pure wax discharged into the same will float at the surface so, that it is not carried back to the container by means of the lower or return pipe 13. In this way, the water is returned from the bottom of the receiver to the bottom of the container, without returning the wax, and a steady and efiectve circulation is produced by the pumpin or jet action in-the pi e 10. The wax eating on the surface 0 the water in the receiver or separator can be readily drawn off. at any time by means of the valve 16. p p

In the embodiment shown, the screen 5 is provided-with a frame 5 of soft wood or other absorbent expansive material that is interposed between the container and its cover, and such frame absorbs moisture and swells, thereby forming a tight joint at the point indicated and preventin leakage.

-The expansion of the frame un er the influence of moisture is, of course, resisted by thelocking or clamping devices 8.

It is' to be understood that the apparatus shown in the drawin is but one embodiment of our inventive idea and'that we have not attempted describe the various modi fications atmay be adopted without digressing from the invention.
