UNITED STATES GEORGE E. ORANGE,
OE sALEM, OREGON.
IMPROVEMENT IN DENTAL PLUGGERS.
Spic aion forming part of Leiteis Patent No. 146,380, dated January 13, 1874; application filed September 6, 1373.
To all whom it may concern:
Beit known' that I, GEORGE H. CHANCE, of Salem, in the county of Marion and State of Oregon, have invented a new and useful I1nprovement in Dentists Plugging-Instruments, of which the following is a specification:
Heretofore the Inetal points vof the instruments used by dentists in filling teeth with i gold have been exclusively of steel.
By the use, instead thereof, of gold rendered of suitable hardness by alloy, I have discovered that important advantages are gained: First, in the prevention of electrical action, always resultant from the contact of two different metals, to wit, the steel tool and the gold iilling. Second, in obviating the danger of minute particles of steel abraded from the plugger, when made of steel, during the operation of iilling remaining in the filling, forming a center of oxidization. Particles of the gold tool, if abraded and mingled with the gold lling, form a homogeneous mass, with no possibility of oxidization. Third, in preventing uny depends.
due force being used, to the detriment of the Operation and pain of the patient, the pliability of the gold point being such that it will bend before an excessive blow, while sutliciently hard for all practical purposes. With gold points, also, it is impossible to destroy by excessive pressure that peculiar spongy condition of the gold lling on which its cohesion invention, I claim as new and desire to secure by Letters Patent- A gold-pointed plugger, or analogous dental instrument, substantially as described.
GEORGE E. CHANGE.
Witnesses: A. I. THAYER, T. B, MosHER.
