    Blake's Improved Foil for Stopping Teeth. and the building up or the restoration of the edges of cutting teeth where the enamel is worn down. My improvements also include the galvanizing or electro-plating of platinum sheets or foil, so that they can be used like ordinary gold foil for filling. To do this, I cover the platinum foil upon either one or both 5 sides with a coating of pure gold. This can be done by the electro¬ plating process, or in any other convenient or 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 the required durability. 10 Having thus described my Invention, what I claim and desire to secure by Letters Patent is,— First. A filling for teeth consisting of the usual base covered with a stratum of platinum or other metal approximating to the color of the enamel of the teeth as set forth. 15 Second. The chemical admixture or alloy of platinum and gold for the purpose of providing an improved dental gold, substantially as above specified. Third. As a new article of manufacture, platinum foil or leaf coated with gold either upon one or both sides, substantially as and for the 20 purpose above described. In witness whereof I, the said Charles Edward Blake, have here¬ unto set my hand and seal, this Eighteenth day of December, in the year of our Lord, A.D. One thousand eight hundred and seventy-three. 25 CHARLES EDWARD BLAKE, (l.s.). Witnesses, Geo. H. Strong. ' j C. M. Richardson.
