UNITED STATES PATENT OFFICE.
THOMAS A. EDISON 0F LLEWELLYN PARK, WEST ORANGE, NEW JERSEY,
PROTECTIVE COATING FOR STEEL AND IRON.
No Drawing.
I To all whom it may concern of this character which when applied to polished steel or iron will effectually prevent rusting thereof.
My invention is based on the discovery that flour of zinc, commonly known as zinc dust, when properly combined with a suitable carrier and applied to polished iron or steel will when sup-h iron or steelis subjected to moisture, rain, salt water spray, etc., effectually prevent rust forming thereon as long as an appreciable number of the particles of zinc dustcontact the iron or steel.
sired, I preferably employ therefor a minture of zinc dust and petrolatuln or a similar unctuous substanne, the mixture being Specification of Letters Patent.
Where a readily removable coating is de- Patented Mar. 21, 1922.
Application filed December 2, 1919. Serial No. 342,009.
For conditions of use where it is not necessary or desirable to render the protective coating readily removable, the same preferably consists of a drying-oil paint, that is, a pa 1nt containing linseed or other drying o1l, 1n which Zinc dust is substituted for the usual lead white, zinc white or other slmilar ingredient. This paint, as is the ease with the ordinary drying-oil paints, can be thinned down by the addition of turpentine so as to render it capable of being readily applied by brushing to the surface which it is desired to protect. It is to be understood that my invention is not limited to the use of the specific carriers for the zinc dust described herein, but that many other carriers may be employed without departure from. the spirit of my invention and the scope of the appended claims.
Having now fully described my invention,
what I claim as new and desire to protect by Letters Patent, is as follows:
1. An easily removable protective coating for steel and'iron comprising a material consisting only. of an unctuous material and zinc dust, substantially as described.
2. protective coating for steel and iron comprising a mixture of petrolatum and zinc dust, substantially as described.
'This specification signed and witnessed 65.
thls 28th day of November, 1919.
' THos'. A. EDISON.
