Oiaims. (Cl. ale-43:):

This invention relatesto new and useful improvements in cleaners and more particularly to a device adapted to catch and hold scale, rust, dirt and all foreign matter that might accumulate or be found in the water or liquid in the cooling system of anywater, or other liquid cooled internal combustion engine or motor.

The primary feature of this invention is to provide a device of the character referred to having a pair of removable filtering elements at each end thereof which are adapted to specifically catch and hold all scale, rust, dirt and all foreign sediment or matter in liquids circulating through a cooling system.

Another important feature of this, invention is to provide a device of this character having said filtering elements adapted for easy and quick removal therefrom for replacing with new elements.

A further feature of this invention is to provide a deviceof the character referred to that is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the 5216133115 or construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming parthereof, wherein like numerals refer to-like parts throughout, and in which:

Figure 1 is a perspective view of the device constructed in accordance with the present invention.

Figure 2 is a vertical longitudinal sectional view taken through. the center thereof.

Figure 3 is a sectional view taken on line 33 of; Figure, 2;

Figure 4 is a sectional view taken on. line 44 of Figure 2.

Figure 5; is a, sectional view taken: on line 5--5 of Figupe 2, and

Figure 6 is a sectional view taken on line 65-45 of. Figure 2.

Referring now to the drawings in detail, wherein for the purpose of illustration, we have; dis;- closed a preferred embodimentofi the invention, the numeral 5 represents an outer filter casing of rectangular shape having its end edges bent outwardly to form flanges 6.

Frictionally held within each end of outer casing 5 are a pair of inner casings 7 and B.

The inner opposing ends 9 and H) of said inner casings l and 8 are provided with perforations H and I2 toward one side of said ends.

Connecting the inner ends 9-: and 10' of said inner receptacles 'I and 8 is a bafile plate i3 which is spaced slightly above an inlet nipple M in the bottom of the outer casing at its center.

The lower portions of casings 1 and 8- are providedwith inlet chambers t5 and i6 having pref erably arched openings H at the inner ends of said chambers.

The inner casings are similar in construction and a description of one will sufice for the other.

A longitudinal bafile plate i8 is suitably secured at one edge 1-9 to the inner end of the inner casing at its imperforate side and inclines toward the perforate side and the outer edge 28 of said baflle plate i8 is spaced slightly inwardly from the outer end of the outer casing; An opening 21 is provided in the upper wall 22 of inlet chamber l-5 on the side of bafile plate i8 adjacent the imperforate sideof the inner casing.

An outlet nipple 22a is provided in the outer casing 5 slightly above-baffle plate t3.

A pair of

end plates

23 and 24 having centrally located sockets 2-5 and ribs 26 radiating from said sockets to the corners of said plates is held against the ends of the outer casing 5 by a pair of clamps 2-7- and 28 having adjustable set, screws 29- at the center thereof which fit into sockets 25, said clamps 27 and 2-8 having clamping arms 30 radiating from the centers of said, clamps which are adapted to clamp said plates 23 and H to the flanges 6 of the outer casing as shown in Figure 1 of the drawings.

In operation, water, or other liquid used in, the cooling system enters inlet nipple 14', under pressure from the water pump, or by gravity, and strikes upwardly against baffle plate l3 and is diverted equally through arched openings 17% into chambers I5 and Fit respectively;

The water in chambers l5 and [6' is then forced upwardly through openings 21 intheupper walls 2:2 ofsaid chambers and passes through filtering material 3| loosely packed at-the imperforateside of'bafile I8 collecting sedimentation, at the side. of the baiiie provided with the filtering material, the water then passing around the end 20 of said bafile l8 into the perforate portion of the chamher and through perforations I I and t2 and then discharged outwardly through outlet nipple 22a.

The inner casings are easily and quickly slipped out of said outer casing for replacing when desired.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understandin of the contally disposed outer casing having its ends open, an inlet extending through one wall of said casing, an outlet arranged in the opposite wall of said casing, a pair of inner casings carried by the end portions of said outer casing, horizontal partitions in the inner casings to provide inlet chambers inthe lower portion of said inner casings, a baflie plate extending longitudinally in the upper portions of said inner casings dividing same into a sedimentation chamber and an outlet chamber, said partitions having openings therethrough leading to said sedimentation chambers, filtering top, a pair of inner casings-carried in the end separating the inlet from the outlet, an inlet chamber in the lower portion of eachof said inner casings having openings adapted to receive liquid entering the inlet and impinging against the baflie, the upper. portions of said inner casings providing sediment collecting chambers having openings leading from the inlet chambers, and filtering material in said collecting chambers, the inner ends of said inner casings at the sediment collecting chambers having an opening through which the filtered liquid passes to the outlet.
