Specification of Letters Patent.
Patented Aug. 7, 1906. Y
applicati@ andv my '1. 1905. serial no. '268.8'01.
To all whom it may concern? Be it known that I, HENRY L. HOLLIS, a citizen of the United States, residing at Chicago;in the county of Cook and State .of Illinois, have invented a certain new and useful .Improvement in the Process for Treating Iron or Steel Objects, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates toA an improved method for treating ironor steel objects, which may be in the form of sheets, in order to provide them with a preservative coating.
In Patent No. 621,084, granted me March 14, 1899, I describe a method for applying a preservative coating to iron or steel objects,
which consists in temporarily inserting the object to be treated in a solution of caustic alkali as an electrolyte, temporarily connecting said obj ect as an anode, with a source of electricity, passing electric current from said source through the object and electrolyte, whereby oxidizing conditions will be furnished at the surface of the object and oxygen'will there be united with the iron to form a protective coating, and then withdrawing the connected iron object from the solution.
In Patent N o. 664,550, granted me December 25, 1900, a similar'method of treatment is described. In this method the object is rst made a cathode for the purpose of cleansing it from foreign material, whereafter the object is made an anode and the process carried out as described in the other patent mentioned. During the coating, however, of the object foreign substances are mechanically deposited thereon which interfere with the uniform appearance of the object or sheets, and if it is attempted to brush or rub these sheets off dry the surface thereof is.. -likely to become marred. I find that by treating the obj ects with oil subsequent to the coating thereof they may readily be brushed andcleaned Without marring or scratching them, and the oil treatment, furthermore, gives a much more uniform appearance and allows the objects to be packed and handled with muchless danger of scratching. The objects also even after the oil is apparently completely and thoroughly rubbed off are found less 'liable to rust than without this oil treatment.
The entire for treating the object is as follows:
pgocess shown in Fig. 1, the object a to be treated is immersed in the solution b, which forms the electrolyte and is adapted through the switch c to be connected with either terminal of the sourcev of current d, the
plate e also in the electrolyte being connected with the current source to complete the circuit. If the object, such as the sheet shown, is sufliciently clean, it-may at once be connected with the source to form the anode, and current then ilowing from the object to the electrolyte causes oxidizing conditions to set to adhere to the object, and it is very diflicult to brush these olf without marring or scratch- 'ing the objects. After the coatingis applied I therefore dry the objects and then immerse them for a very short time in a bath of oil,
which is preferably heated, the degree of heat depending on the kind of oil. With a mineral oil the temperature is kept below the flashing-point; but I ind that very good results can be obtained by using palm-oil, the temperature thereof beingraised to approximately 125 centigrade. After removing the objects from the oil-bathV they are brushed or rubbed with bran or any other material that willnot scratch the sheets, but will absorb and remove the oil. This treatment might also be carried 'on with oil at ordinary temperatures; but the use of heated oil is much more economical for the reason that the oil in a heated condition runs OH" the objects much more rapidly and completely, also lessens the labor in ment.
Objects treated in this manner require much less care in handling and packing, as
the danger to marring or scratching is greatly lessened on account of. the oil treatment, and
the objects will also resist rust for a much longer time.
The electrolytic'solution may be any suitable oxidizingand cleaning reagent, such as caustic soda or any other caustic alkali.
and thereby the cleaning treatthe electrolyte and object whereby oxidation will take place at the surface of the object and oxygen will there be united with the iron to form a the object rom the solution and drying it,
and then immersing the object in oil.
2. The method of providing'a protective coating for iron objects which consists in immersing the object in a suitable electrolyte, passing current throughI the electrolyte and object to cause oxidizing conditions at the surface of the object, whereby oxygen will be united with the iron to form a coating, removing the obj ect from the electrolyte and drying it, immersing the object for a short time in oil, and then rubbing off the oil with soft material. l
3. The method of providing a preservative coating to iron objects which consists in subjecting the iron object to oxidizing conditions to form thereon a coating, thereafter immersing the object in oil, and then rubbing off the oil. C
4. The method of treating an iron obj ect to provide a protective coating therefor which consists in causing oxidation of the iron toiform thereon a protective coating of -iron oxid, thereafter immersing the object in oil, and then removing the oil therefrom.
5. The method of treating iron objects to provide a preservative coating therefor which consists in subjecting the iron to oxidizing infiuence to form thereon a coating of iron oxid, thereafter temporarily immersing the object in heated oil and then absorbing and rubbing off the oil.
6. The method of treating iron objects to rotective coating, withdrawingl provide therefor a preservative coating which consists in electrolytically causing the formation of a coating of iron oxid thereon, drying the obj ect, and immersing it in oil.
7. The method of treating iron objects to provide therefor a preservative coating which consists in electrolytically causing the formation of a coating of iron oxid thereon, drying the object, immersing it in oil, and then absorbing and rubbing od the oil.
8. The method of treating iron objects to provide a preservative coating therefor which consists in electrol tically causing the formation of a coatingo iron oxid thereon, drying the object, immersing it temporarily in heated oil, and then absorbing and rubbing off superfluous oil.
9. The method of treating iron objects to provide a protective coatingtherefor which' consists in immersing the object in an electrolyte, causing -the passage of current through the electrolyte and object to cause the formation of a coating thereon, removing the obj ect from the electrol teand drying it, thereafter immersing the o ject tem orarily in a bath of heated oil, and then rub ing the object with soft material to dry it from the oil. f
10. The method of treating iron objects to provide a protective coating therefor Which consists in immersing the object in an electrolyte consisting of caustic alkali, suitably passing a current of electricity through the electrolyte and obj ect to cause formation of a coating on the object, removingthe object from the electrolyte and drying it, thereafter immersing the object for a short time in a bath of heated oil, and then rubbing the object with bra`n, sawdust or other soft material to absorb and dry the oil therefrom.
In witness whereof Ihereunto subscribe my name this 1st day of July, A. D. 1905.
