Letters Patent No. 78:842, dated June 9, 1868; antedatecl June 2, 1868.
IMPROVED'ARTIFIGIAL IVORY.
TO ALL WHOM IT MAY CONCERN:
Be it known that we, Atrnun STARR. and WILLIAM M. WELLING, of the city and-State of New York; have invented and made a certain new and useful Compound for-an Artificial Ivory, especially adapted. to the Inanul'acture of plates for artificial teeth; andwe do hereby declare the following to be a full, clear, and exactdescription of the same, aud'of its mode of preparation. V
The ingredients employed by us are finely pulverized and thoroughly mixed together. They are heated in a suitable vessel and stirred,-and then passed through rollers heated bysteam, and moulded into shape while hot, by pressure between suitable dies, and the article itself can be turneilsfileil, sawed, orv otherwi finished and polished according to the article to be produced. I
The aforesaid manner of mixing and working the ingredients corresponds generally with that set forth in Letters Patent, granted August 4, 1857, to said WILLIAM M. WELLING.
The ingredients employed by us are used in about the following proportions:
Shellac, sixteen parts, by'weight.
Gu m-copal, one and a half part, by weight.
Gum-camphoxj one part, by weight.
Talc, or aminnthus, eight parts, by weight. V
'The tale maybe used alone, or mixed with the amianthus, and can for some uses be employed to the extent of sixteen parts, with the other ingredients the same as before named.
Thisco cu iound is very strong. It is not in any manner influenced by the salivaof the mouth, or by food or drinks taken 'into the mouth. It is light and durable, and although especially adapted to plates for artificial teeth, may be used for any purpose for which it is available.
Any desired coloring-matter 'may be introduced into this compound. For dental uses, cal-mine may be employed for the plates, and for filling teeth this compound may be inixed with impalpable white or other pigments.
What we claim, and desire to secure byLetters, Patent, is The compound herein specified, prepared as setforth. I In witness whereof, we have hereunto set our signatures, this twelfth day of November, 1867.
ALFRED STARR, WM. M. WELLING.
