UNIT D STATE-S PATENT OFFICE.
WILLIAM A. O. IVUTH, OF PITTSBUBG, PENNSYLVANIA, ASSIGNOR TO HIIVL SELF WASHINGTON BECK AND HENRY FEUBHAKE, OF SAME PLACE.
IMPROVEMENT IN METHODS OF CLEANING GLASS-MOLDS.
Specification forming part of Letters Patent No. 221,138 dated October 28, 1879 application filed October 2, 1879. i
To all whom it may concern:
Be it known that I, W. A. OTTO WUTH, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new known of removing it is by scouring the-mold.
with a stone dipped in oil or emery; but this is objectionable, because almost invariably the mold is made uneven thereby, is soon worn away, and the pattern, if any, is ruined by the rubbing off of the clear sharp lines and corners. It is only by preserving these clear sharp lines' and corners that it is possible to obtain pressed glassware resembling cut glassware.
In addition to this it is an operation which, owing to the hardness of the oxide, requires much time and labor, and is consequently a large item of expense, as the molds and plungers have to be cleaned every day. An on dinary plain mold will take from one to two hours to clean.
There are many molds of fine andintricate pattern which are never cleaned, because it cannot be done without injuring or ruining them. a
By my invention I can remove the coating of magnetic oxide from the mold or plunger, andrcstore it to its first finish in a short time, without destroying, injuring, or changing itsoriginal surface or pattern; and it consists in treating the mold or plunger to a bath of melted borax, phosphate, or silicate of soda, or similar salt, which, uniting with oxide, separates it from the metallic iron, and forms therewith a glass, leaving the mold or plunger in a clean condition.
To enable others skilled in the art to use my invention, I will now describe its use and operation.
I melt a sufficien't quantity of borax, phos phate, or silicate of soda, or other equivalent salt, in a suitable kettle to form a bath, in which to immerse themold or plunger which is to be cleaned. The borax unites with the magnetic oxide, destroys its cohesion to the mold, and forms a colored glass. The mold is then taken out of the bath, and will be found to be coated with a film or enamel of glass, which, when the mold becomes cold, may be easily removed by slight blows of a suitable hammer, wooden mallet, or other instrument, as it is very brittle, or by immersing it in.
boiling water.
It is necessary, in order to prevent the mold from becoming reoxidized, to permit it to cool, either as described or by remaining in the bath until. the bath becomes cold, before it is exposed to the air, as the action of the air upon it while heated causes its reoxidation.
After the removal of the glassy film adhering to the mold when it is taken out of the bath, it will be found to be entirely free from the coating of magnetic oxide, with, its finish unimpaired, and in condition for imme diate use.
The same bath may be used many times, its properties not being impaired by use. Its
quantity, however, will be gradually diminished, and it must therefore be replenished from time to time.
Themolds and plungers may be placed in the'bath immediately after being used, and while still hot from such use. The cost of the bath will be very small. The salt will not attack or injure the metallic iron of the mold.
By this means I am enabled'to effect the perfect removal from molds and plungers of the coating of magnetic oxide without labor and without injury to the pattern or surfaces 1 thereof, and at very small expense.
What I claim as my invention, and desire to secure by Letters Patent, is-
The Wltllll1-dQSCPib6d method of cleaning In testimony whereof I, the said W. A. glass molds and plungers, consisting of sub- OTTO WUTH, have hereunto set my hand. initting them to a bath of melted borax phos- 7 phate, or silicate of soda, or other salt, VhlCh, WILLIAM AUGUST OTTO WUTH' uniting with the coating of magnetic oxide Witnesses: of iron on the molds and plnngers, will form JNo. K. SMITH,
a glass therewith, substantially as described. T. B. KERR.
