My invention relates to new and useful improvements 1n clean-out devlces, and more particularly toa device whereby metal bore ings, core sand, and other foreign matter device which is of simple construction and which is efiicient in operation. I v

While the invention has wide application in the cleaning of hollow bodies, it will be found particularlyuseful in the cleaning of hollow cast bodies such as radiators. It is well known that foreign matter such as metal borings, cutting oil, core sand, and the like, which may remain within a radiator casting, and if not removed, will clog the valves, traps and heating systems in general in which the radiator is installed. Heretofore it has been. necessary inmany instances to take down the system after a period of use in order to clean out the foreign matter from the working'parts of the valves, traps, etc. By my invention 1 radiators may be properly and efficiently cleaned out before installation in. a system, and the objectionable and expensive taking down of the system thereby obviated.

The invention consists in the improved construction and combination of parts, to be more full described hereinafter, and the novelty of which will be particularly pointed out and distinctly claimed. I r a In the accompanying drawings, I have fully and clearly illustrated a preferred embodiment of my invention, to be taken, as a part of this specification, and wherein- Figure 1 is a vertical central sectional view,

Referring to the drawings by characters of reference, 1 designates generally a hollow body, for example, a radiator, which has been formed by casting and then machined. The

radiator which I have shown in order to illustrate the invention, is built up of three sections, 2, 3, 4, but the number of sections is immaterial so far as my invention is concerned, as the radiator may be of anynumber of sections. Each section has oppositelydisposed openings 5, 6 at its base 7, andanother pair of oppositely disposed openings 8, 9 atits top 10. These openings are internally threadsealed together at top and bottom by reversely threaded hollow tapered nipples 11. The end opening 8 at the top of section 2 and the opening 9 at the top of section 4, are each closed and sealed by a threaded'plug- 12. The base or bottom openings 5 and 6, respectively, in sections 2 and .4 serve as. inlet and outlet, it being immaterial which outside base opening is chosen as inlet or outlet. In the drawings I have shown the opening 5 as the inlet open ing, and into this opening is inserted an inlet fitting 13 having a nozzle 14 surrounded by a resilient packing member 15, adapted to seal the opening -5 against egress of waterfrom the interior of the radiator or hollow body around thenozzle 14. The nozzle 14 is fed with Water under pressure by a. conduit 16. In the fitting 13 is control valve 17 of any suitable or desirable type, such, for example, asa gate valve. 4 I

I will now proceed to describe a novel washout device 18 whereby a cleansing stream of Water admitted through the fitting 13 will be caused to be deflected into contact with foreign matter in the hollow body to agi' tatethe foreign matter so as to be lifted or thrown into the fluid stream and be carried out of the outlet orifice 6 in the section4. The wash-out device is shown in Fig.1 as being inserted in said outlet opening 6. The wash-out device comprises a hollow cylindrical plug or nipple 19 having a through outlet passage 19 andexternal threads 20 which are adapted to engage the internal threads of the outlet opening 6 -to position said device in said opening This plug or into and across the interior chamber of the section 4. In the preferred form the baffle is substantially that of a segment of a hollow cylinder in cross-section (Fig. 3) and the longitudinal elements of which are straight lines, and if detached from the nipple and fiat would have substantially the form shown in Fig. 4, which in general outline is that of a sector of a circle. The apex 22 of the sector forms a projecting lip extending partially across the passage 19, and the circumference or arc 23 of the sector is sealed to the circumferential or annular end wall of the nipple, so that the bafile makes" an angle of substantially forty-five degrees with the longitudinal axis of the nipple. The top of the nippleis designated, as at 24, preferably by a notch or slot, so that the battle will be properly positioned andha've apex 22 pointing downward, as shown in Figs. 1 and 2. Upon'referenceto Figs. 1 and 2 of the drawings it will be seen that the 211-023 is of such length and' the baffle extends downward such distance that the bafiie obstructs only a portion of the crosssectional area of the passage 19 and the lip 22 projects over the portion of said passage which is not obstructed by the main body of the baflie. It will also be seen that in side elevation the bafile is substantially triangular. The baflle overlies or intercepts the passage through the nipple, so as to deflect flow from .said passage in a manner to be presently described. V j

The radiator having been assembled and the fitting 18 and nipple 19 having been applied thereto, as shown in Fig. l, the operation is as follows Water under pressure in conduit 16 1s admitted through the nozzle 14 into the hollow body or radiator by opening valve 17. -The stream of water passing through the base of the radiator impinges upon the upper inclined face of baffle 21 and is deflected laterally, and following'the contour of the upper face of the baffle is turned downwardly into the pocket at thebase of section 4, in which pocket foreign matter may be trapped or collected during 7 hydraulic testing of the radiator, orby the stream from nozzle 14 washing down the surfaces it contacts and moving such matter tocess to the outlet passage.

ward the outlet. The deflection of the stream in the manner stated is accomplished by the baffle causing the stream being-turned later ally, due to the formation of the battle, and seeking to follow the contour of the adjacent inner wall of the radiator before finding ac- This flow serves to agitate or lift any foreign matter out of the pocket in the end section 4 and elevate such matter into the. path of thestream flowing to so that by I, permitting the stream to flow for a sufficient and through the outlet opening,

length of time substantially all foreign matter will be cleaned'out of the radiator and said pocket. The water is deflected downwardly by the baffle into the pocket, because the stream being divided and caused to flow laterally, will strike the adj acentside walls of the radiator section and will then have to flow down before it can find access to the outlet. It will be understood that for best results the water stream should be under sufficient pressure so that it'will be deflected laterally with sufficient force to strike the walls of the sec tion and be guided thereby with sufficient force into the pocket at the baseof the radiator,"so as to agitate the foreign matter to lift it to a point where it can be caught and removed'by the stream flowing out through the passage in nipple 19. It Will be understood that some of the stream from the nozzle 14 passes directly, beneath the inner edgeof the baffle and is not deflected, and that. this por tion of the stream catches the foreign matter when agitated and removes the same through the passage in the element 18, so that both the 1.
