Definitions

  • My invention relates to a substitute for goldfoil, to be used for dental and other purposes where it may be desired to unite the sheets or leaves of foil, or pieces of them, one to another, by percussion or otherwise.
  • My invention consists in preparing platinum foil or leaf so that it may be used for dental purposes in the same manner that gold-foil has heretofore been used.
  • Platinum-foil possesses all of the qualities which render it valuable as a filling for decayed as desired, with a coating of pure gold. This can be done by the electroplating process, or in any other convenient and suitable manner.
  • platinum-foil When thus prepared, platinum-foil can be used for filling and restoring decayed teeth in the same manner that gold leaf or foil is now used, and at the same time it will provide a more durable filling than gold. It also enables me to disguise the bright color of the gold, as recited in the Letters Patent which have been granted to me for disguising gold.

Description

UNITED STATES PATENT OFFICE.
CHARLES E. BLAKE, OF SAN FRANCISCO, CALIFORNIA.
IMPROVEMENT IN METALLlC FOILS FOR DENTAL PURPOSES.
Specification forming part of Letters Patent No. 145,274, dated December 9, l8 73; application filed November 10, 1873.
To all whom it may concern:
Be it known that I, CHARLES E. BLAKE, of San Francisco city and county, State of California, have invented an Improved Metallic Foil for Dental Purposes; and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.
My invention relates to a substitute for goldfoil, to be used for dental and other purposes where it may be desired to unite the sheets or leaves of foil, or pieces of them, one to another, by percussion or otherwise.
My invention consists in preparing platinum foil or leaf so that it may be used for dental purposes in the same manner that gold-foil has heretofore been used.
Platinum-foil possesses all of the qualities which render it valuable as a filling for decayed as desired, with a coating of pure gold. This can be done by the electroplating process, or in any other convenient and suitable manner.
When thus prepared, platinum-foil can be used for filling and restoring decayed teeth in the same manner that gold leaf or foil is now used, and at the same time it will provide a more durable filling than gold. It also enables me to disguise the bright color of the gold, as recited in the Letters Patent which have been granted to me for disguising gold.
