COMBOSITION FOR REPAIRING LEAKS.

. {It is another object of this invention to provide a leak stopping composition for hot Water circulating systems which Wlll not only repair all leaks which may be present 1n the s stem at the time this composition 1s place therein, but which will prevent leaks from forming while this composition is in the system, and which will also keep the 1nterior of the system cleansed and in goodcondition.

I attain the above stated objects by mixing a composition of aluminum, flax seed meal, trisodium phosphate, soda ash and soap and placing the same in the hot water circulating system. The above ingredients Wlll product '30 the desired effects when the proportions are varied greatly, but I find that the most desirable proportionsare as follows:

Percent. Aluminum Flax seed meal 5O Tri-so dium phosphate 15 Soda ash A l2 Soap 11 40 When this composition is placed in a hot water circulating system containing aquar tity of watenthe last three named ingredients dissolve and form a colloidal solution. The soap, stimulated and strengthened in its action by the tri-sodium phosphate and the soda ash, exerts a strong suspending and cleansing action. The suspending action prevents the agglomeration of the insoluble materials in'the mixture, and therefore, prevents the stoppage of the circulatory system.

The insoluble materials are left as a somewhat fluffy mixture and are stirred up by the circulation of the system.- The suspended particles work their way into the leaks in the Application filed April 12, 1927. Serial No. 183,243.

The moderately alkaline solution prevents any separation of the fatty acids of the soap and helps to prevent the formation of any oily or greasy deposit on the inner walls of the hot water circulating system. The phosphate, the carbonate and the soap produce a very efficient suspending agent for the insoluble matter, and also have a very satisfactory cleansing action on the interior of the hot water circulating system.-

If the soda ash were. omitted from the mixture the solution would not be quite as alkaline, and the action of the aluminum would be somewhat lessened, which would be quite desirable in aluminum head engines. Also the sealing of the leaks would be accomplished more by the aluminum phosphate and less by the other compounds if the soda ash were omitted.

In the specification I have set forth a preferred embodiment-of my invention, and although specific terms are employed, they are used in a generic and descriptive sense, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. A composition for stopping leaks in hot water circulating systems comprising a mixture of aluminum, flax seed meal, tri-sodium phosphate, soda ash and soap.

2. A composition for stopping leaksin hot water circulating systems comprising a mixture of aluminum, flax seed meal, trisodium phosphate and soap.

3. A composition for stopping leaks in hot water circulating systems comprising a mix-- ture of aluminum, flax seed, soda ash and trisodium phosphate.

In testimony whereof I affix my signature.
