STATES Patented January 1'7, 1905.
PATENT OFICE.
PLASTIG GOMFUUND.
SPECIFICATION forming part of Letters Patent No, 780,240, dated January 1'7, 1905. Application filed October 15, 1904. erial No. 228,631.
To all whom it 777/061] concern:
Be it known that I, THOMAS JEFFERSON SPITZER, a citizen of the United States, residing at Morristown, in the county of Hamblen and State of Tennessee, have invented a new and useful Plastic Compound, of which the following is a specification.
This invention relates to plastic compounds used for molding pottery, artificial-stone coffins, tombstones, bath-tubs, and similar articles, and has for its object to provide a compound of this character which when molded into the desired shape and thoroughly set or solidified will effectually resist the deleterious action of the elements for an indefinite period.
With this object in view the invention consists in a compound formed of the following ingredients, to wit: plaster of-paris, fifty pounds; pulverized sulfur, four pounds; pulverized alum, two pounds; dried sawdust, two pounds, and pulverized borax, four ounces.
In carrying out the invention the above ingredients while in a dry state are thoroughly mixed together in a vessel or other suitable receptacle, so that the several parts will be well blended, after which a suflicient quantity of hot water is added thereto to give the same the consistency of thin paste. The compound is then introduced into the mold and allowed to set until the molded product is sufficiently hard for use, the time required being found in actual practice to be from four to five hours.
If desired, any suitable pigment or coloring material may be added to the compound in-order to give the same different shades or tints.
Articles molded from a compound thus prepared present a hard moisture-proof surface, will not crumble or disintegrate, and will not freeze when subjected to an intense degree of cold.
Having thus described the invention, what is claimed is A plastic compound consisting of plaster of-paris fifty pounds, pulverized sulfur four pounds, pulverized alum two pounds dried sawdust two pounds, pulverized borax four ounces, the whole being combined with hot Water in the manner substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
THOMAS JEFFERSON SPITZER.
