GASOLINE FILTER.

Application filed April 12, 1926. Serial No. 101,240.

invention relates to filters and more particularly to one adapted for use in connection with a system of cleaning articles of clothing or other fabrics with a fluid, such as gasoline, in continuous flow through washer and clarifying elements; the principalobject of the invention being to provide a simple and economical filter whereby water may be separated from the more volat1le cleaning liquid during circulation of the fluid in the system.

In accomplishing this object I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein Fig. 1 is a central, longitudinal section of a filter embodying my improvements.

Fig. 2 is a transverse section of the same.

Fig. 3 is a detail perspective view of a.

filtering material which I prefer to employ with my device.

Referring more in detail to the drawings, 1 and 2 designate sections of a pipe through which cleaning fluid is circulated in the system and in which my filter is interposed.

The filter proper preferably comprises a cylindrical housing 3, having a conical bottom 4, through the apex ofwhich the pipe section 1 is extended to deliver cleaning liquid to the interior of the filter. Re-

movably located within the housin 3 is a screen 5, preferably comprising a body of wire mesh mounted on end rings 6, of channel iron, the flanges of which are directed outwardly to engage the wall of the housing 3 and space the screen therefrom in order to provide an outer, annular chamher 7 through which the liquid must even-.

tually flow to reach the outlet pipe section 2. Located interiorly of the screen 5 is a drum 8, preferably formed of sheet metal having closely arranged and relatively small straining apertures 9 in its side wall, and havin a bottom wall 10 comprising a flange 11 whlch fits snugly over the pipe section 1 and is flared at its free end to form a mouth 12 for guiding the flange 11 over theend of the pipe when the drum is inserted into the housing; the edge of the flange seating within a cup 13 attached to and forming a part of the bottom ofthe tank. The drum 8 is of substantially less diameter than the screen 5 to form-a chamber 14 therebetween.

Enclosing the drum 8 is a strainin jacket 15 preferably consisting of cotton attlng 16.1ined on both sides with muslin or like fabric 17, through which a thin liquid may pass; but by'which any impurities or sediment contained in the liquid will be caught to effect its separation therefrom. The bag 15 is preferably closed at its opposite ends by draw strings 18, the lower one of which surrounds the flange .11 of the drum 8 to which it may be tied to securely attach the bag in place.

Located within the drum 8 is a second like drum 19, also composed of sheet metal having apertures 20 in its side wall and having a closed bottom 21 provided with a sleeve 22, having a flared mouth 23 by which the drum is easily fitted over the end of the pipe 1 and spaced from the bottom 10 of" the drum 8. The drum 19 is also enclosed by a fabric filtering member 24 of construction similar to the covering 15 and provided with draw strings 25 and 26, the latter serving to tie the filter member onto the neck of the drum. The drums 8 and 19 are open at the top but. entirely enclosed by the filtering members 15 and 24, so that any impure cleaning fluid entering the filter must pass through said filtering members to reach the outlet to the washer, the drums being of progressively lesser height in order that they may be spaced at their ends to form horizontal chambers at their tops and bottoms, as well as annular chambers at their sides.

The filter is adapted for vertical arrangement, and in order to eflect the removal of impurities accumulating in the bottom thereof I make the bottom 3 of the housing as a cone and provide the cone bottom with an outlet fitting 27 through which sediment or impurities may be drawn and through which any water accumtrlated in the filter below the outlet of the pipe may be removed. lhe housing 3 is open at the top but normally coveredcby a lid 28 having a keeper flange fitting snugly within'the top of the housing to prevent accidental displacement of the lid but permitting removal of the lid when access to the interior of the'filter is desired for cleaning, replacements or other purcorporate the filter as a semipermanent art of the system. The screen 5 is then slid into the housing from the top with the flanges of of the drum over the pipe 1 until the ange seats in the cup 13 where it is held with sufficient firmness to maintain the drum upright within the housing. .The drum 19 with its fabric covering is then lowered into the drum 8, the fabric covering for the drum Sbeing opened at the end to permit the insertion of the inner drum and then closed by its drawstring.

When these parts are assembled, the lid 28 is applied to the housing to cover the contained elements. When the cleaning liquid is in circulation through the system it enters the bottom of the interior drum 28 the apertures in the drum and through the fabric covering into the drum 8, where the filtering process is repeated and the filtered liquid passed into the chamber 14: and thence through the screen 5 into the chamber 7 from which it escapes through the pipe section 2 when'the liquid reaches the level of the pipe.

It is apparent that by passing the cleaning liquid through the three filtering bodies the impurities remaining inthe fluid after passage through the ordinary clarifier of a system of this 'kind, will be removed before delivery of the cleaning liquid in the Washer and particularly will the fabric elements filter out the water from-the more volatile cleaning liquid.

By arranging the filter elements as deof the housing, concentrically thereof, a screen located within the housing and spaced from the wall thereof, a da drum open at its upper end and having a neck at its lower end slidable on the intake pipe, the drum having a perforated side wall and a fabric ing, a screen located Within the housing and spaced from the side wall thereof, aperforated drum open at its upper end andhaving a neckat its lower end fitted over the intake pipe, a fabric cover enclosing said drum, and means removably attaching the cover to the "neck-of the drum. through the pipe 1 and flows out through.

3. A filter of the character described comprising a cylindrical housing having a coni- .cal bottom, a feed pipe extending through the bottom concentrically. of, the housing, a screen located within the housing and spaced from the side wall thereof, a drum having a perforated side wall and closed bottom, the

bottom having a neck slidably fitting the intake pipe and having a flared flange seating the drum on the bottom of the housing, the

drum having an open top, and a fabric cov- 3 ering substantially enclosing the drum and tied to the neck thereof, 1

4:. A filter of the character described, comprising a cylindrical housin'g'having a tapered bottom, an intake pipe extending through the bottom, concentrically with the housing and upwardly into the interior of,

the housing, a on on the bottom of the housing about the intake pipe, a drum hav-- ing a neck fitted over the intake pipe and having a flange seating in the cup, a fabric member covering the sides and ends of the drum, andmeans for tying the covering to the neck' of the drum.

In testimony whereof I afiix my signature.
