ALLEN A. nowsnn, or roar WAYNE, INDIANA AssIGNon 'ro s. F. isowsrneJ a co.,


specification bf Letters Patent..

Application led March 30, 1911. Serial No. 617,886.

To all whom t may concern i Be it known that I, ALLEN A. Bowsnn, a citizen of the United States, residing at Fort Wayne, in thecounty of Allen and ,State of Indiana, have invented certain new and useful Improvements in Separators, of

` v which the following is a specification.

This invention relates to separators and has for its primary object to provide an improved, simple construction, combination and arrangement of parts for eecting the separation of the ingredients of a mixture ina rapid and eiiicient manner.

More particularly the object of this invention is to provide means for separating iuids of different specific gravities.

y Another object of the invention is to provide a separator of improved construction adapting it for direct connection with a nozzle.

A further object of the invention is to provide means for discharging a liquid of greater specific gravity adjacent the nozzle connection of the separator.

For the attainmentof these ends my invention consists in the construction, combination and arrangement of parts generally shown in the accompanying drawing and .described in the specication, but more par-v ticularly pointed out in the claims.

In the accompanying drawing, Figure 1 is a longitudinal section of the preferred embodiment of my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a cross sectional view on the line 33 of Fig.` 1.

Referring more particularly to the` drawing, a cylindrical member 5 is provided with end members 6 and 7, the'former of which is formed with an inlet opening 8 and an outlet opening 9. The outlet opening 9 Y communicates with a central chamber 10 and the inlet opening 8 communicates with a chamber 11 disposed about the central opening lO/and being inclined downwardly from the inlet opening 8. A 'cylindrical partition 12 provided with a helical ridge 13 is adapted to be inserted within the cylindrical member 5, the ridge 13 formin in conjunction with the cylindrical partition 12 and the cylinder 5 a helical passage forming a continuation of the chamber 11. The

cylindrical partition 12 extends a portion only of the length of the cylinder 5 and detition are filter screens 14 and 15. These screens are preferably of dierent fineness of mesh,'the nner screen being inside of the other. The bottom member 7 is formed with an 'opening 16 through which an ax- 1ally extending tube 17 is adapted to extend, the lower end of the tube being threaded to receive an acorn nut 18, the other end of the tube being threaded into the opening 19 in the top member 6, a portion of the tube extending therethrough to provide a means for connecting the angle valve 20 thereto, thus binding the top and bottom members amg 7 together about the ends ofthe cylinf The tube 17 extends through the bottoms of the lte'r screens 14 and 15 and longitu` dinally of the central opening of the separator and adjacent the lower end of the tube there is provided a number of openings 21 which are adapted to provide communicalratentea nar. ce, raie..

the lower portion of the separator. A filter screen 22 surrounds the tube 17 at this lower portion to prevent the openings 21 from becoming clogged or large particles from being carried into the tube.

When a mixture of fluid is introduced into the separator the helical passage imparts to it a whirling movement whereby the iiuid of greater specific gravity is thrown yby centrifugal force outwardly and the lighter iuid remains nearer the cylindrical partition and nearer the filter screens. The filter screens are of such fineness of mesh that the inner screen will permit the passage of the lighter fiuid therethrough but will prevent the heavier fluid from passing. The heavier fluid gravitates to the bottom of the separator and is drawn o from the separator through the tube 17 and the cock 20.

When there is a comparatively large amount ofthe heavier fiuid the angle Valve or cock 2() may be left open at `which time the heavier fluid will be discharged continuously through the pipe 17, but if there is a comparatively small amount of the heavier iiuid in the fluid mixture, it may be drawn off at any time by the opening of the valve.

With this construction it is evident that the heavier fluid is discharged adjacent the top of the separator in close proximity to the nozzle or inlet connection and the discharge may be regulated as desired.

In case the filter fills up with water the ldischarge is closed and the shut of cock of the filter is opened, and When the inlet is opened the Water is forced out through the hole at the bottom of the pipe and up through the cock connected with the filter, the Water on account of its specific gravity being collected at the bottom of the filter, and the only opening to the pipe in the center of the filter being at the bottom of the separator the Water is forced out through the top.

While this separator is particularly adapted for the separation of Water from gasolene it is evident that it may be employed in any connection Where it is desired to separate fluids of different specic gravities.

In a separator, the combination with a tion of the length of said vessel, said partiy tion being adapted to provide an inlet passage eXtending around the inner Wall of the vessel and a discharge passage Within, filter screens between said passages, and a tube disposed Within the discharge passage and providing a passage from the bottom through the top` of the vessel.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 27th day of March, A. D. 1911.
