Oct. 10, 1939. 1.1-: ROY 0. BROWN LIQUID FILTERING RECEPTAGLE Filed Oct. 18, 1937 DIS Patented Oct. 10, 1939 UNITED STATES PATENT OFFICE LIQUID FILTER-ENG RECEPTACLE Illinois Application October 18, 1937, Serial No. 169,539

4 Claims.

The particular object of the present invention is to provide a receptacle for liquids which is equipped with eificient means for filtering the liquids introduced into the receptacle before the same are discharged therefrom, the invention comprehending the use of a filtering device which presents an adequate area to cause the liquid to seep through the filtering element into the main body of the receptacle at a sufiicient rate of flow to assure an adequate supply of the filtered liquid at all times for discharge from the receptacle.

A further object of the invention is to provide a receptacle equipped with filtering means of the type aforesaid which is collapsible and foldable so that it may be introduced through a relatively small diameter opening into the receptacle and to be similarly removed therefrom for cleansing purposes, and wherein said filtering device is suitably held against movement in a direction to obstruct the discharge spout of the receptacle when the latter is tilted into discharge position.

A suitable embodiment of the invention is illustrated in the accompanying drawing, wherein Fig. 1 is a central vertical sectional view of a receptacle constructed in accordance with the invention.

Fig. 2 is a fragmentary, sectional view of the same taken on the line 2-2 of Fig. 1 and showing the collapsed filtering device secured to the intake tube of the receptacle.

The receptacle I may be of any desired shape and size and may also be equipped with a discharge spout 2 of suitable shape and disposed at a convenient point, it being obvious, of course, that in order to maintain the filtered liquid in the receptacle clear of dust, etc., that the discharge spout should be sealed by means of a suitable device 3.

In the instance illustrated the receptacle is equipped with a. discharge spout and a sealing mechanism therefor such as is fully described in Letters Patent of the United States No. 1,954,983.

The intake port 4 of the receptacle is bordered by an annular threaded flange 5 which receives the threaded sleeve 6. The said sleeve 6 is equipped with an annular threaded flange l for engagement by the sealing cap 8.

Suitably secured to the sleeve 6 is a tube 9 Which is disposed concentric therewith and is provided between its ends with an annular bead H Said tube 9 is equipped at its upper end with an annular flaring flange H which is soldered or otherwise suitably secured along its outer edge portion to the said sleeve 6 along a shoulder portion [2 of the latter disposed between the lower end portion of said sleeve and the upper threaded end portion 1 thereof.

A fabric filtering bag I3 is equipped with a neck M of a diameter slightly larger than that of the tube 9 and receives the latter, said neck M of said bag I3 is detachably secured to the tube 5 along the bead ll! of the latter by means of a suitable metallic strap I5, as shown in detail in Fig. 2, composed of a strip of ductile sheet metal having its ends passed through slots in a plate l6 and having its free ends bent outwardly to secure said strap to said plate;

Secured to the lower end portion of the tube 9 by soldering, or otherwise, are the upper ends of the arms of a U-shaped member I! made of a strip of sheet metal which projects downwardly into the bag I3 to a point adjacent to the bottom of the latter.

The neck M of the bag I3 is secured to the tube 9, while the sleeve 6 is removed from the annular flange 5. Said bag is then collapsed and folded about the U-shaped member I! so that it will be passed through the flange 5 in the body of the receptacle. The cap 8 being then removed, permits liquid to be poured into the upper end portion 7 of the sleeve 6 and through the tube 9 into said bag l3 to fill the latter. As the liquid fills the bag I3, the latter expands, obviously, so that its lateral dimensions become substantially equal in all directions, the capacity of said bag being, preferably, substantially one-half of the capacity of said receptacle I and the walls of said bag l3 presenting a very large filter area for the seepage of the liquid through the fabric to filter said liquid.

As the receptacle is tilted to discharge position, the U-shaped member I! prevents the bag from moving to a position wherein the flow of filtered liquid from the discharge spout will be obstructed.

A filter bag l3 must be cleaned or replaced at intervals and because of its collapsibility, as aforesaid, it is readily removed from the receptacle, detached from the tube 9, washed or otherwise cleaned and replaced.

I claim as my invention:

1. A receptacle for liquid equipped with a discharge spout adjacent one side thereof and equipped at a substantially opposite point with an inlet port, a flange bordering the latter, a removable device detachably secured to said flange and equipped with a sleeve projecting into said receptacle, a fabric filter bag secured at its mouth portion to said sleeve for causing liquid to be first received in said bag for seepage through the walls of the latter, a device secured to said sleeve and projecting downwardly into said bag for preventing the latter from swinging to a position to obstruct flow of liquid from said discharge spout when said receptacle is tilted to discharge position, and a closure cap for said bag detachably secured to said removable device.

2. A device of the kind specified comprising a receptacle equipped with oppositely disposed and spaced apart intake and discharge ports, a rigid flange bordering said intake port, a removable sleeve detachably engaged with said flange and equipped with a tube projecting through said port, a fabric filter bag secured at its mouth about said sleeve and extending to the bottom of said receptacle and when expanded being of appreciably greater lateral dimensions than said intake port, a closure cap detachably engaged with said sleeve and a U-shaped wire of less width than the diameter of said intake port rigidly secured at the upper ends 01" its arms to said sleeve and projecting downwardly to a point adjacent the bottom of said bag within the latter for preventing said bag from obstructing the discharge port of the receptacle when the latter is tilted to discharge position.

3. A device of the kind specified comprising a receptacle equipped with oppositely disposed and spaced apart intake and discharge ports, a rigid flange bordering said intake port, a removable sleeve detachably engaged with said flange and equipped with a relatively short tube and a relatively long arm, a filter bag, said arm projecting into the said bag to appreciable depth and said bag being secured at its mouth portion about said tube, and a closure cap detachably secured to said sleeve for sealing the outer end of said tube.

4. A device of the kind specified comprising a receptacle equipped with oppositely disposed and spaced apart intake and discharge ports, a rigid flange bordering said intake port, a removable sleeve detachably engaged with said flange and equipped with a relatively short tube open at its ends and projecting through said intake port, a U-shaped member having the upper ends of its arms secured to said tube, a fabric filter bag embracing said U-shapcd member and secured at its mouth portion about said tube, said bag when expanded by liquid introduced into the same through said tube being of appreciably larger cross sectional area than said intake port and .ieing collapsible for passage through the latter, said U-shaped member being adapted to prevent said bag from obstructing the discharge port when the receptacle is tilted to discharge position.
