To all whom concern I Be it known that I, WlILIAM H. ALLEN, a citizen ofthe United States, and residing at Detroit, inthekcounty of Wayne and State which'is .kept approximately boiling for a suflicient length-of time, such surface being of -Michigan, have invented a new and proved Rust' Preventing and Arresting Solution, of which the following is a specification. w.
This invention relates to means for are resting and preventing the oxidation of the surfaces ofarticles of iron and steel, and its ob]ect is to provide a liquid compound which may be applied while cold to such suriaces by means of brushes or air currents,
or may be used as a dip or bath.- Q A been known that a weak aqueous solution of phosphoric acid and' certain. acidsalts thereof will produce a surface 'ofiron phosphates ,on articles of" It has long iron and steel when left the solution rust-proof-under ordinary atmospheric conditions. But many structures-of iron and steel such as bridges and freight cars cannot be placed in a rust-proofing bath, and, after their surfaces are rusted, it is a very diflicult'matter to. arrest oxidation; .B rushing'to remove the rust and then painting has been found to work only moderately well, as -the paintscalesipflt'v and rusting ofiensgoes'on under thelpaintn 1 Spraying' with an active rustroofing so lution" as'been'-foimd'.-to work s'prayin is followed by painting butwhere e. sui'; acesjare covered with'a heavy layer of rust, and especially where 'the ysurface-fl is anywhere nearly upright so that the solusi n will adhere only as ayer'y-thifi film, -the action of the solution not very-satisfactory. This is'particularly true for-the ason that the" liquid quickly dries and becomes ineflective.
, I have found 'that deep rust can becompletely altered, that is, changed to'insoluble phosphates, by means of a solution of phosphoric acid or acid phosphates containing a small amount of inert miscible compounds.

Such substances greatly retard the evaporationof the water from therust-proofing solution and many will so thicken the solu with the very thin film usually obtained.
"Such inert substances have no apparent effect chemically, but. serve v to retain the water 1n such coating under atmospheric exposure and such conditions'bring abouta results. The phosphates-of ironformed by said reactlon are part of the surface of the metal andconstitute a rust-proof protecting I find that glycerin and certain carbohydrates such as glucose. and levulose conform to the above conditions, and that good results are obtained by using seventy parts of ordinary fifty per cent. strength phos phoric acid, twenty partsv of glycerln or glucoseiand thirty parts of water, that is,
