PATENT OFFICE. I
MATAIGHI YASUDA, 0F KOISHIGAWA, TOKYO, JAPAN.
COMPOSITION FOR POLISHING II'ION.
No Drawing.
To all whom it may concern.
Be it known that I, MATAICHI YASUDA, a subject of the Emperor of Japan, residing at 'Koishigawa, Tokyo, in the Empire of Japan, have invented certainnew and useful Improvements in Compositions for Polishing Iron, of which the following is a specification.
My invention relates to a metal polish and particularly to a composition of matter for removing rust and the like from iron.
I-Ieretofore it has been a common practice to remove rust from iron by the use of abrasives and particularly by the use of sand paper, or by dipping it into an acid such, for example, as sulfuric acid.
I have discovered that rust can be removed from iron and the metal given a satisfactory polish by the application of a composition hereinafter set forth containing ingredients which react chemically as described, with components of the rusted surface whereby such surface may be easily rendered clean and bright.
In the preparation of my polishing com position I employ a salt formed by uniting a weak base and a stron acid such, for example, as ammonium c orid, ammonium sulfate, alum or the like. To this I add a powdered metal which has a stronger ionizing tendency than that of iron such, for example, as zinc, magnesium, and aluminum. To this I preferably add an abrasive powder of a high degree of hardness such as powilrllred rock crystal, powdered topaz, or the The following is an example of the composition of my polishing powder in its pre- Parts by welght. Powdered metallic aluminum 2 Dehydrated alum 3- Finely-powdered crystalline silica. 5 In the use of m composition the powder is preferably applled to a water soaked cloth and rubbed steadily on the surface of the iron to be cleaned andpolished. The rust gradually disappears and by continued acti a brilliantly polished surface results. %he polished surface is then wiped off to remove the: adhering composition and water and a suitable grease such as Vaseline or the, like may then be advanta ously applied. thereto to preserve the polis my composition Specification of Letters Patent.

is in the form of powder, its constituents are in contact and capable of reacting freely with each other and the iron rust upon the application of water.
The explanation of the polishing action of my compo: :ition is believed to be as fol lows:
The salt is dissolved by the water on the cloth and in contact with the powdered metal disassociates, the negative ion of the salt combining with the metal in the powder, and hydrogen in a nascent state being liberated in contact with the rust on the surface of the iron. This nascent hydrogen acting upon tie iron oxid reduces it whereby its easy removal is rendered possible.
It is advan zageous to employ an abrasive powder such as powdered crystal silica to scratch the rust or oxidized surface of the metal whereby the action described-is more readily efi'ectr :d.
It is kIlOWI. that certain metals, such for example as zi no, can be deposited upon iron by the action of a third metal which is electro positive with respect to iron, in the presence of a salt capable of producing an aqueous electrolyte when brought into contact with Wat er. My invention is however distinguished from this metal coating process and composition employed therein as I employ no ooatin metal nor, in fact, any metal capable of being deposited on the iron by the metal having a greater ionizing tendency on the silt employed than iron.
Having described my invention, I claim: 1. A composition of matter for cleaning and polishing iron, which comprises a salt of a strong acid and a weak base, an uncoated finely divided metal having a greater ionizing tend :ncy thereon than iron, and an abrasive powder, said composition having metal capable of being deposited on the iron by the action of the said finely divided metal.
'2. A composition of matter for cleaning and polishin; iron, which comprises three parts by wei rht of dehydrated alum, two
parts by weight of finely-divided uncoated f. metallic aluminum, and five parts by weight of powdered crystalline silica-,- said composition having the ingredients thereofin intimate contact and capable of reacting freely with each other and with the iron rust and adapted upon the addition of moisture to remove rust from iron with which it is placed in contact, such composition being free from any metal capable of being deposited on the iron by the action of the said finely divided metal.
In testimony whereof I aflix my signature in presence of two witnesses.
