Abstract
1,231,417. Dental engines. KALTENBACH & VOIGT. 6 Nov., 1968 [8 Nov., 1967], No. 52697/68. Heading A5R. [Also in Division F2] A dental angle handpiece 1 has a head part 3 including a shaft 9 rotating a swash plate 11 acting on the ends of two push rods 12, 13, whose opposite ends engage a drive sleeve 16 so as to convert the rotary motion of the shaft and swash plate to an oscillating rotary motion of the drive sleeve. The sleeve which receives the shank 15 of a dental tool such as a dental canal instrument, is cylindrical and is mounted in the head part of the instrument at right angles to the longitudinal axis thereof so that a recess provides surfaces 16a which are engaged by the tapered ends of the push rods. The head (3) is held on the lower part 1 of the angle handpiece by a sleeve 2. A gearwheel 6 on a drive shaft 5 of the handpiece meshes with a gearwheel 7 on the shaft 9 so that driving power can be transmitted at an angle. The swash plate face 11a may be inclined at an angle of between 50 and 60 to the longitudinal axis of the head part.
