ART OF DETERGING RADIATORS Application filed December 17, 1830. Serial No. 502,956.

This invention relates to the art of deterging radiators, and has for an object to provide improved means for expelling from radiators employed in conjunction with automotive vehicles and the like, the several acin top plan,

cumulations formed within said radiator.

A further object of the invention is to provide a receptacle into which a radiator may be introduced and to which, in such receptacle, may be attached the necessary facilities for carrying out the art which will be hereinafter more fully explained.

A further object of the invention is to introduce into a radiator a solution of detergent material which will cause the sediment and other accumulations within the radiator to separate from the walls of the radiator and then to introduce suddenly and violently air under pressure to expel the detergent solution, together with the accumulated deposits.

A further object of the invention is to provide steps in the art of deterging a radiator, which consists in introducing water in a heated condition into the radiator to fill the said radiator to capacity, evacuating the radiator, filling with a detergent solution, permitting the detergent solution to stand for a suflicient length of time to liberate the accumulations from the walls of the radiator, and then shocking and expelling the detergent solution by the sudden concussive admission of air under pressure to form substantially an explosion within the radiator to expel the solution and dislodge any still clinging accumulation from the walls or cells of the radiator.

Like characters of reference indicate corresponding parts throughout the several views.

The art which forms a part of the present invention may be carried out'by the use of a great variety of mechanical devices, or with only the most rudimentary of such mechanical devices.

The showing in the drawings of a com plete installation for carrying out and practicing the art is no limitation upon the invention, and is merely an illustration of a con-- venient and fully equipped installation for the purpose.

It comprises a tank 10, preferably having inclined sidewalls so that the rear wall 11 is higher than the front wall 12.

The tank thus constructed is preferably covered over the greater portion of its area, leaving, however, an opening, as indicated at 13, for access thereto. The cover may be of any type desired.

A section 14 is shown in the drawin as being rigidly attached to the tank 10 with the section 15 hinged thereto by the hinges 16. This, however, maybevaried as occasi'on may make necessary or desirable.

Located somewhere adjacent to the tank 10 is a reservoir 17 which may be of substantially and usually the .ordinary 'stand boiler type with an inlet 18 for water, and a'hea-ter, indicated as a gas heater, 19.

Also located adjacentg tojth a second-reservoir 20 which inainlet 21-Ic0ntrolledby a valve 22 mcontrolhug the flow of water from the'reservoir 17 into said reservoir 20. Provision is made for heating the reservoir 20, a gas pipe and burner 23 being indicated at Figure 1.

wk ;-1O..'i$ y I be similar .to the reservoirili'and is. provided. with. an

convenience may make desirable.

Extending into the opening 13 is a pipe 28 which is fitted with a nozzle 29 to be hereinafter more fully described. The pipe 28 is connected through a pipe 30 controlled by a valve 31 from the air reservoir 24.

A pipe 32 communicates also with the top of the water reservoir 17 and is controlled by a valve 33,making connection with the pipe 28 through a coupling 34. A pipe 35 extends from the chemical reservoir 20 and also makes connection with the pipe 28 after passing through a control valve 36.

The nozzle 29 is provided with a semispherical end 37 as shown in detail at Figure 4, and a section of flexible tubing or hose 38 is attached thereto, covering the semispherical part and the perforations 39 being closed, solution fr m the reservoir 20 therein.

The hose section 38 issecured upon the nozzle 29 by the hose clamp 40. This section of hose 38, as shown at Figure 3, is of suflicient length and flexibilit to be bent ,into the necessary angle to ma e connection with the normal outflow connection 41 of the radiator 42. The connection 43 of the radiator is the connection normally at the top, the filling cap 44 indicating such top position.

A cap 45 is provided for closing the connection 43 and the usual overflow pipe 46 is shown as extending below the lower end of said radiator.

In operation, the detergent material. is introduced into thereservoir 20 through the filler openin 47 and water admitted thereto through t e pipe 21, to form a solution of the necessary strength. The solution in the reservoir 20 is under pressure of air through the pi 48 from the air reservoir 24, t e water 1n the reservoir 17 being under pressure of the normal water supply.

The radiator 42, being removed from the vehicle, is laid into the tank upon the strips or cleats 49 to support it off the bottom of the tank. The radiator cap at 44 is now put in position and the hose section 38 attached to the lower connection 41.

Hot water from the reservoir 17 is now admitted through the pipe 32 by the mao.

nipulation of the valve 33 to fill the radiator, such filling being indicated byoverflow at the overflow pipe 46. The water is maintained in the radiator until the radiator has reached a temperature substantially equivalent to boiling water or to water at very high temperature.

Air is now admitted through the valve 31 to expel the water from the radiator, or the r part thereof, and the air valve .ficient amount, the valve 36 is closed, the

valve 33 again opened and water admitted to complete the filling of the radiator. Thus filled, it is allowed to stand for a short time, which may be from one minute on to any desired length of time, but a very short period of time will usually sufiice.

this solution admitted de-T of the solution, but

The normal inlet fitting 43 is now closed 7 by the cap 45 and the filler opening 44 o ned. The valve 31 is now suddenly opene wide so that air under pressure from the tank 24 will pass through the nozzle 29 and the perforations 39 through the hose section 38 to the radiator, and will violently and concussively shock and expel all of the fluid and solution within the radiator, together with the deposits which have been loosened and separated from the wallsof the radiator by the detergent solution, as well as liberating and separating and discharging others not yet completely separated.

The employment of this air concussively under pressure, suddenly admitted in considerable volume and great force to shock the radiator parts, is believed to be the controlling'step in the art. It is, however, necessary that the air, as it enters the hose pipe 38, shall be broken up to form air bubbles in the liquid as thereby a reverberatory efiect is produced and it is therefore found desirable to employ perforations 39, as shown in the semi-spherical part 37 of the nozzle.

It will be noted that one row of perfora I tions is practically covered in normal position by the hose section 38. When introducing water, the solution, or even air under normal conditions into the radiator, the outer row of perforations is not em loyed as it is covered by the flexible hose section 38. At the final inlet of the air, however, when it is introduced in the radiator, in great volume and under great force, the force through the perforations expands the hose pipe 38, so that all of the perforations are employed for the air and the volume of air is thereby not diminished.

Of course, after the detergent solution-has been expelled from the radiator, watenis further employed from the reservoir 17 for the purpose of washing out any solution which may remain and further use of air nd a pressure may be employed-and be repeated if found necessary or desirable.

Of course, the invention herein illustrated may be in va Ways without (19-.

parting from the invention herein set forth and hereinafter claimed.

The invention is hereby claimed as follows:

1. The art of deter 'ng a radiator, consisting in filling thQIQdlfltOI-Wlth a liquid, and then shocking and evacuating the contained liquid violently by the sudden introduction of a large volume of air under high pressure, said air being separated into several jets as it is so introduced.

2. The art of deterging a. radiator consisting in filling a radiator with a liquid, and then producing a. violent concussive expulsion of the liquid, by the introduction of numerous jets of air under pressure simultaneously to form a bubbling intermixture of air and water throughout the radiator.

3. The art of deteriing a radiator, consisting in introducing t erein water at a high temperature for the purpose of heating and expandi the radiator, expelling the heated water an suspended material from the radiator, introducing at a high temperature into the radiator a detergent solution, permitting the detergent solution to stand a suflicient length of time to perform a cleavage'ofthe deposits from the walls of the radiator, introducingconcussiveli air underhigh pres,- sure to violently shoe and expel the detergent solution from the radiator, and flowing water therethrough to wash out the remaining solution and deposits. Y

In testimony whereof I have signed my name to this specification.
