This invention relates to a device for cleaning the radiators of automobiles and the like. The usual method hitherto employed for cleaning these radiators has consisted. 1n re- I moving the radiator from the automobile and boring a hole in the bottom of the radiator at the side remote from the outlet stem. Compressed air, together with tap water under the usual pressure of a city water supply l0 system, was then introduced into the radiator through the outlet stem at the lower portion of the radiator through a rubber hose connection thereto, and compressed air was also introduced into the radiator through the aforesaid hole by means of a suitable connection thereto, the purpose having been to cause the air to rise through the water tubes at both Sides of the radiator, thereby loosening the impacted material or deposits from the 1nterior of all the tubes equally, the loosened deposits ascending through the radiator with the flowing water and being discharged therefrom with the water through the inlet stem or the radiator cap opening. After the completion of the cleaning operation, the hole that had been made in the bottom of the radiator had first to be closed by soldering a plate thereover, prior to replacing the radiator in its position on the automobile.

Accordingly, the present invention aims to provide means whereby the radiator may be cleaned internally without irst having to remove it from its position in the automobile; without having to bore the aforesaid hole in the bottom and subsequently having to reclose it; and without having to lose time in making inconvenient soldered or hose connections to the hole in the bottom of the radiator or to the outlet stem. Other objects and advantages will appear in the course of the following description of an illustrative embodiment of the invention.

In the accompanying Idrawings forming part of this specification, in which like numbers of reference denote like parts wherever the occur,

igure 1 is a rear elevation of an automobile radiator, showing the cleaner of this invention attached to the outlet stem thereof;

Figure 2 is a fragmentary sectional view of the cleaner, taken on the line 2--2 in Figure 3;

Figure 3 is a view of the detached cleaner, looking at the side that is presented to the outlet stem or pipe of the radiator, and with l parts broken away; and

Figure 4 is a sectional view taken on the line. 4 4 in Figure 1.

The illustrative embodiment comprises a conduit-bearing body or casing 1 that serves as a closure member for the open end of the hollow stem or outlet pipe 2 of the automobile radiator 3. The casing 1 is clamped against the end of the pipe 2 by means of a clamping frame 4, comprising an annular portion or ring 5 that embraces the pipe 2 and a U-shapcd portion 6 whose ends rise from opposing portions of the ring 5. A plurality of set screws 7 extend radially through and in threaded relation to the ring 5 at equal angular intervals, and are adjusted to clamp against the wall of the pipe 2. A set screw 8 threads through the intermediate portion 9 of the U-shaped portion 6 that extends behind the member 1, and is adjusted to force the casing 1 against the open end of the pipe 2. An annular gasket or washer 10, preferably of rubber, is interposed between the end of the pipe 2 and the seating face 11 of the casing 1 to facilitate the making of a leak-proof connection.

A plurality of threaded openings 12, 13 and 14 are formed in the annular wall 15 of the casing 1. A short threaded pipe or nipple 16 passes in threaded relation throu h the intermediate opening 13, and is pre erably secured tightly by means of a locknut 17. The inner end of nipple 16 threads tightly into the short arm 18 of a pipe elbow 19, the other arm 20 of which extends through a sleeve portion 2l that rises from the edge of a central opening 22 in the seatin Wall 11. The outer end of arm 2O is threade exteriorly to receive the internally threaded end 23 of a iexible conduit or hose 24. Conduit 24 passes through pipe or outlet stem 2 into the interior of the radiator 3, as best shown in Figure 4, and then extends along the bottom of the radiator toward the side remote from the stem 2, as best shown in Figure l, and

then preferably terminatesin a non-flexible upturned end 25. A nipple 26 is threaded .into the opening 12. Nipples 16 and 26 are connected to respective valves or cocks 27 and 28 through the intermediation of pipe unions 29 and nipples 30. Valves 27 and 28 are pref-= erably formed in a single casting or casing 31 and both communicate with a common or single inlet conduit 32, having a nipple 33 threaded thereinto. A short pipe 34 threads into the opening 14, and a sleeve 35 threads on the outer end of pipe 34. The outer end of sleeve 35 is threaded at 36 to fit a water hose connection.

With the device attached to the radiator as shown in Figures 1 and 4, a conduit leading from a source of com ressed air is connected to the ni ple 33; an a hose leading from a source o water under a suitable pressure is connected to the nipple 35. Valves 27 and 28 are opened to admit air from their common conduit 32 into their res ective conduits, 16 and 26, and the tap to w 'ch the water hose is connected is o ened to admit water into the conduit 34. ater from ipe 34 and air from pipe 26 enter the cham r in the casing 1 and discharge therefrom. through opening 22 and sleeve 2l to enter the hollow outlet stemfpr pipe 2 and the radiator 3. The air rises in the passage of the pipe 2 and ascends through the water in those tubes of the radiator that are juxtaposed to the passage of the pipe 2. However, air also asses through the pipe 16, the elbow 19, and t e flexible conduit 24, emerging from the end 25 of said iexible conduit and bubbling up through the water tubes that are disposed thereover, or on that side of the radiator remote from the pipe 2. It will be observed that the flow of water is controlled independently ofthe flow of air, and that the valves 27 and operatedindependently of one another tos'regulate the How of air as may be required at opposite sides of the radiator. The use of this evice makes it unnecessary to remove the radiator and to bore a hole in its bottom in order to clean both sides of the radiator in an equally thorough manner; and the device can be easily attached or detached without having to make special or soldered connections. The device is also useful for cleaning the water jacket of an internal-combustion engine, the flexible conduit 24 serving to distribute the air to arts remote from the inlet opening of the `ac et to which the device is connected.

aving thus fully described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claims.

I claim:

1. A. cleaner of the. character described comprising a casing having an opening, said 1,sse,eee

tending therethrough and projecting through i said opening to a oint remote therefrom.

2. 1n a device o the character described, a i

casing provided with an exit opening for fluid and a pair of entrance openings for receiving fluids, a conduit having a diameter smaller than that of said exit opening and extending through the casing but bein out of communication with the interior o the casing and extending through said exit opening, and a second conduit branching olf from the first conduit and terminating at one of the sald entrance openings.

3. In a de vice of the character described, a casing having an exit opening and three en trance openings, said casing being adapted to be connected to a passage to a chamber wlth sald exit opening opening into said passage, a conduit extending through one entrance opening and through said casing and projecting through said exit opening in spaced relation to the walls of said exit opening, means connected to that end of said conduit which projects through said exit opening and adapted to extend through said passage and into said chamber to convey a gas to said chamber, a second conduit connected Within another entrance openingrto convey a gas into said casing and a third conduit connected with the remaining entrance openlng to convey a liquid into said casing.

4. A cleaner of the character described comprising a casing adapted for connection to a passage to a chamber, said casing having an opening toV discharge into said passage and being provided with three conduits, means for controllin each of said conduits indeendently of t e others, one of said conduits eing adapted to convey liquid into the casing, another to discharge gas intothe casing, and the other being extended through the casing and of a length to extend into the chamber to a remote point thereof to discharge gas into the chamber at a point remote from said passage.

In testimony whereof I hereunto ailix my signature.

GEORGE C. PECK.
