DENTAL FILE.
SPECIFICATION forming part of Letters Patent No. 408,92 6, dated August 13, 1889. Application filed May 13, 1889. Serial No. 310,623. (No model.)
To all whom it may concern:
Be it known that I, CHARLES E. PALMER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Dental Files; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in
Figure 1, a perspective view; Fig. 2, a transverse section 011 line a: as of Fig. 3; Fig. 3, an
This invention relates to an improvement in files for operating upon the teeth of horses and other animals, the object of the inven tion being to construct a file with a guard as an integral part thereof, and so that the said guard may form substantiallya continuation of the cutting-surface of the body of the file 5 and the invention consists in a file which in transverse section presents a flat surface, having a guard upon one edge curved into the flat surface of the body of the file, the said curved surface and flat surface forming a continuous file cutting-surface, and as more fully hereinafter described.
A represents the body of the file, which is preferably forged with the handle B as an integral part thereof. a flange is turned at substantially right angles to the body to form the guard O. Theinner surface of this guard C is curved into the working-surface of the body. as seen in Fig. 2, and so that the guard and body form a continuous surface. This continuous surface of the guard and body is cut in any suitable manner for forming a file, the cutting continuing throughout the inner surface of the body and guard, and so that a continuous fileworking surface is produced from one edge of the body to the opposite edge and onto the On one edge of the file.
guard. The body of the file is longitudinally curved, so as to present a convexworkingsurface, as seen in Fig. 3.
In use the file is taken in the hand in the usual manner of holding a file, the thumb resting against the guard and finger on the back of the body of the file, and so that the filing or operation upon the teeth may be produced by the file cutting-surface of the guard and body, the curved surface between the guard and body giving a rounded effect upon the tooth.
The handle may be made separate'from the file and attached thereto-say as by a tang, as indicated in broken lines, Fig. 1; butI prefer to make the handle as a part of the body of the file, as it is stronger and more convenient than an attached handle.
I do not claim, broadly,a file presenting an inward or concave curved surface, as such, I am aware, is not new.
1. The herein-described dental file, consisting of a body A, with a flange 0 turned from one edge, the inner surface of the flange curved into the corresponding surface of the body, the said inner curved surface of the flange and the body out to form afile cuttingsurface throughout, substantially as described.
Theherein-described file, consisting of the body A, the handle B, made as an integral part thereof, the body constructed with a longitudinal flange 0 upon one edge, the inner surface of the said flange curved into the adjacent surface of the body, the said in ner curved surface of the flange and thebody cut to form a continuous file cutting-surface throughout, substantially as described.
