    J\° 5881 A.D. 18m Date of Application, 20th Mar., 1893 ■Complete Specification Left, 20th Dec., 1893—Accepted, 17th Mar., 1894 PROVISIONAL SPECIFICATION. Improvements in and relating* to what are called or known as Dental Eng*ines. I, Arthur Gillett Taylor o£ 29 Poland Street London, W. Dental Manufacturer, do hereby declare the nature of this invention to be as follows :— My invention relates to what are known in mechanical dentistry as dental buring engines briefly denominated dental engines. Hitherto a dental engine has '5 comprised or consisted of the following main elements namely :—Driving wheel surmounted by the upper part of engine including ratchet head, flexible wrist, hand piece &c. Now in order to simplify and reduce the cost and construction of dental buring engines, I in accordance with my present invention, dispense wdth the upper parts 10 of the engine above enumerated, with the exception of the handpiece, and I construct my improved simplyfied dental engine in the following manner,—that is to say :—The driving cord from the usual grooved driving wheel is conducted to two small pulleys arranged on a short stem piece above the driving wheel, and thence to a small pulley with which the stem of the handpiece is provided. 15 It will be found in practice that apart from the simplified cost of con¬ struction, dental engines constructed in accordance with my invention will possess the following amongst other additional advantages namely :—Great steadiness of rotation,less friction, and the avoidance of “backlash,” possessing the advantage also of great portability. :20 Dated this 17th day of March 1893.
