LIQUID, GASOLINE, ANIQ OIL FILTER.

Application filed. A ril 1a, 1928. Serial no. 269,464;

, simple construction that it is readily and easily assembled. iThe filtering elements are held in axial alignment by a plurality of U- shaped or any other suitable shaped ribs, made of bendable material, such as round or flat wire or of any other similar material. Two or more of these ribs may be used for each filtering element. This construction provides a method whereby the maximum surfaces of the filtering elements are utilized for filtering purposes. Theseribs are detachably or otherwise secured to the closing caps and are mounted on the inside or outside of each filtering element, thus holding the filtering elements concentric one with the other.

A pair of containers or receptacles adapted to contain the liquid are used, the same being detachably secured, or otherwise secured together by means of a conduit, or they may be cast as an integral structure. This system equalizes the liquid in the containers, also forms two sediment chambers adapted to collect the particles of grit and water that might accidently pass'through the filtering elements, and each chamber is terminally equipped with an outlet opening and is provided with a pet cock to drain 0d the water and grit that collects in these chambers. The containers may be drained without removing the filtering elements. The device also provides a means whereby a process of continuous filtration may be carried on when in use. The filtering elements may be read,- ily removed from the containers for removal or cleaning when and as desired.

Other advantageous features of the invention will be fully understood from the following description when the same is considered in connection with the accompanying drawings forming a part of this specification, in which,

Figure 1 is a view, partly in elevation and partly in vertical section, illustrating the device constituting one embodiment of my invention.

Figure 2 is a plan view of the device shown in Fig. 1, with the openings in the walls left off.

Figure 3 is a bottom view of one of the containers, with the closing cap. ribs and filtering element, taken in the plane indi= cated by line A, A, in Fig. 1. k v

Figure 4. is a side view of the ribs.

Similar figures designate corresponding parts in all views of the drawing, referring to which,

1, l, designates suitable containers or receptacles, they may be of any suitable size or shape, intercommunicating through a con duit 2, spacing the containers, the conduit providing means to allow symmetrical dis tribution of the liquid in the containers.

Each

closing cap

3, 3 is provided "with a de pending or detachably secured central nozzle d on their under side, and also with a plurality of

annular shoulders

5, 5, the-said shoulders extending concentrically into said containers and spaced therefrom. Each of the shoulder portions is adapted to accommodate a difierent size of filtering ele ment. Each shoulder portion is provided with an intermediate annular groove 6, ti, or may be provided with serrated peripheries if desired, for securing the filtering elements thereto by means of wire or cord 7, or any other suitable fastening means. Each closing cap also has bored or otherwise formed therein a series of

sockets

8, 8, adapted to detachably secure the

terminal ends

9, 9 of the

ribs

10, 10, therein. The bores may be positioned around the periphery of the shoulder portion if desired.

The filtering elements comprise a plurality of

concentric bags

17, 17, made of felt or other fibrous material. The central filtering element is supplied in the ordinary manner from the tank or oil supply through the conduit 11 and the nozzle. The nozzle extends almost to the bottom of the central filtering element, its purpose being to carry the liquid down to the bottom of the bag first, at which place the grit and dirt is deposited and detained. The liquid then rises around the nozzle in the bag and is conveyed by capillary attraction into the space between the inner and outer filtering elements. From this location it is again filtered into the 'con-' tainer. When the second process of filtering takes place, the liquid then flows into contact with the outer filtering element in the second container through the conduit. It is to be understood that this unit is constructed the same as the unit previously describedi Since the liquidin the second container comes into bon- 60 in, and equippe tact with the outer filtering element first, then it is self evident that it is conveyed by capillary attraction into the space between the outer and inner filtering elements, from whence it is again filtered through the inner filtering element into the space surrounding the nozzle from whence it is drawn off through the conduit 12 for use. The

caps

13, 13 are adapted to close the openings in .0 the walls of the containers when these openings are not in use. It will be seen that by placing an integral partition in the conduit located between the containers, the unit is made into two distinct filters. Vith such an 15 arrangement, one side can be used to filter oil while at the same time the other side can be used to filter gasoline, it will be understood that the

caps

13, 13, are removed to provide outlets for the liquid. The

sediment chambers

14, 14, are located in and at the bottom of the containers. The

terminal openings

18, 18 are provided with

pet cocks

15, 15 adapted to drain the chambers or containers as desired. The

openings

16, 16, in the walls of the containers are adapted to provide a means to connect conduit therein in making the various and different connections if desired. The sealing means 19, 19. are positioned between the containers and the closing caps to provide liquid tight joints.

It will be readily understood by those skilled in the art after understanding my invention that the filter may be connected in the oil and gasoline line in a number of different ways, if desired, and arranged to either independently or collectively filter the liquid.

I have explained my invention by illustrating and describing onespecific embodiment thereof but it will be readily understood by those skilled in the art that the invention may be embodied in other forms than that shown and described. The number of filtering elements, is obviously not limited to a single pair in each container, or the shape 15 of the ribs and also the shape of the container as illustrated. The terms of the appended claims are, therefore not restricted to the precise structure disclosed, but are intended to cover all changes and modifications within the spirit and scope of my invention.

What I claim is 1. In a liquid filter, a body member having a lengthwise-extending conduit interposed between its halves, a sediment chamber formed at the bottom of the body member,

cured to each cap and enclosing the nozzle, means within each element and mounted in each cap adapted to cause each element to assume and maintain a bag formation.

3.
