Abstract
A straight dental handpiece comprising a pair of telescoping housing barrels which can swivel relative each other, one containing a chuck and the other containing a vane type air motor. A change speed transmission is entrained between the motor and the chuck, such transmission being adjustable to change speeds by relative endwise movement of the barrels. Opening and closing of the chuck is accomplished by relative rotation thereof a limited amount. A reversing valve, also on the handpiece, is movable into either of two positions to apply air under pressure to either of two passages to drive the motor in one direction or the other.
