2 Claims.

The subject-matter of the present invention relates generally to the art of collection and separation of materials, but more specifically has to do with a device for the arresting and collection of foreign materials present in the cooling fluid of the circulatory system of an internal combustion engine, or the like.

Primarily, the object of the invention is to provide a device of the above-mentioned character which may be conveniently installed between the outlet pipe of the water jacket of an internal combustion engine, or the like, and the inlet in the tank at the top of a radiator, without materially altering the present constructions.

Another object is to provide a device adapted to receive and house a trap element suitably constructed to receive foreign materials arrested by a screen borne by the upper end of said element.

A still further object is to provide means serving as a guide whereby said trap element and its screen element may be positively arranged in a predetermined position within the tubular portion of the device.

Still another aim of the invention is to produce a device that may be attached to the tank of a radiator by difierent ways and methods.

Other objects and advantages will ,be apparent as the nature of the invention is better set forth, and it will be understood that changes within the scope of the claims may be resorted to without departing from the spirit of the invention.

In the drawings:

Figs. 11, 12 and 13 show difierent methods of attaching the device to the upper tank of a radi- 1 ator.

jacket ll of an internal combustion engine, re-

spectively. Said casing also includes a tubular extension l2 disposed angularly with respect to the longitudinal axis of said tubular portions, as shown in Fig. 2, and being adapted to receive 15 a trap member I3 having a bottom 44, the wall of said member being cut away to present an opening [5 which aligns with the passageway in said tubular end portions 6 and I when the parts are assembled as in Fig. 2. Upon inspection of Figs. 2 and 3 it will. be noted that the upper end of said member I3 is cut on the bias to support a screen I6. As shown in Fig. 1 the end portion 6 is coupled to the inlet pipe 8 by means of suitable rubber tubing ll, whilst he end portion 1 is joined to the outlet pipe I!) by means of rubber tubing l8, suitable clamping members l9 and 20 being resorted to. The casing is preferably made of rust-proof material and in view of the opening IS in said trap element I3 the circulating cooling medium has a clear passage through the tubular portions 6 and I, said screen I6 interrupting and arresting foreign substances in said cooling medium and preventing the passage thereof to said radiator, thus preventing clogging, or the like. As shown in Fig. 2 said screen It is inclined at an acute angle to the transverse plane of said tubular portion and in this position it provides for the deposit of foreign substances and their subsequent descent into said trap member l3, said member having a bottom I4 for retaining said substances.

In assembling the device for use, the trap member I3 is pushed upwardly into said extension l2 and to assure that the screen It is properly positioned within the casing, the Wall of said extension is provided with a rib-like formation 2| which cooperates with grooves 22 in said trap member l3, in an obvious manner. The bottom M of said member I 3 is provided with a handle 23 which facilitates the entry and removal of said trap member and the latter isim'ally in the position indicated in Fig. 2 by means of-a cap 24 and a washer 25. Said cap 24 may be threaded the bight portion 3| of said ball engaging the abutment 32 to assure a tight fit. When the bail is swung to the position indicated by dotted lines in Fig. 5, the cap may be removed. To properly mount the trap member with its screen at the necessary position, I propose to provide slots 33 which receive the side portions of the handle-like element 34, as shown in Fig. 6. The trap member will also be provided with a certain marking, as indicated at 35 in Fig. 3, to assure that the screen will be properly positioned.

When the usual symptoms of a clogged strainer or screen make themselves apparent, the cap 26, or the cap 21, may be removed and the trap element 13 can be drawn out of the extension l2 for cleaning so that all materials in said member and all foreign matter clogging said screen'are removed and the trap member replaced for further service.

In Fig. 7 the casing 36 is provided with

end portions

31 and 38, theformer portion being provided with a flange 39 which is suitably riveted .said end portion 31 is provided with threads 41 to engage a threaded nipple 48 suitably fastened to said tank 40. Reverting to Fig. '1 it will be noted the tubular extension 48 extends downwardly from said casing 36 and receives the trap element 49, having a bottom 50, the upper end being cut on the bias and carrying a screen 5| disposed in the passageway of said casing 36. The rear of said element 49 is cut away at 52 so the cooling medium may flow uninterruptedly through said passageway. Said screen 51 arrests the passage of foreign substances in said cooling medium which drop into the trap element 49 for subsequent removal. In order to properly position said trap element in the extension 48, the latter is provided with diametrically opposed slots 53, see Fig. 9, to receive the ends of the -handle-like element 54 carried by the bottom 58 and the cap 51 is secured in position by means of the bail 58 pivotally carried by said extension a,os4,242

'48, asshown. The bight portion of said bail is snapped over the abutment 59 in the same manner as pointed out hereinbeiore. I! desired, the end of said extension 48 may be threaded to engage a threaded cap 01 the type shown in Fig. 2.

The use of the device assures that the cooling medium will circulate in a satisfactory manner and that all foreign. substances will be restrained from entering the top tank oi a radiator and the tubes thereof, thus preventing overheating of the engine or an impairment to the satisfactory operation of the cooling system.

I claim:
