    N° 89 A.D, 1900 Date of A pplication, 2nd Jan., 1900 Complete Specification Left, 2nd Oct., 1900—Accepted, 17th Nov., 1900 PROVISIONAL SPECIFICATION. Improvements in Veterinary Dental Forceps. We, Benjamin Franklin Pinson and John Calvin Stephenson, both of Blackwell, Kay County, Oklahoma Tearitory, U.S.A,, Inventors, do hereby declare the nature of this invention to be as follows; — This invention relates to new and useful improvements in dental forceps for 6 veterinary use; the object of the invention being to provide an article of the kind which will be of simple but most elhcacous construction. Our improved forceps comprises a stock or handle which is longitudinally perforated and has a forwardly extending lug at one end in which transversely- disposed cooperating jaws are mounted upon longitudinal pivots so as to swing 10 transversely of the stock. The upper part of each jaw has an arm which ex¬ tends over an eccentric or cam mounted at one end of a rod extending through the perforation in the stock and fitted with a handle or knob by means of which it can be rotated. When the handle or knob is rotated the eccentric or cam bears upon the arms 15 and causes the jaws to close towards each other and grip the tooth. In an alternative form the jaws are provided with extensions at their upper parts between which a tapered wedge or cam can be forced by a rod screw- threaded in the stock and capable of being rotated by the handle or knob afore¬ mentioned to cause the lower ends of the jaws to grip the tooth. 20 Dated this 2nd day of January 1900. 1\ R.
