Abstract: A labeling device which includes a pair of spaced printing element carrying, rotatable wheels for imprinting characters on a tape. A path of travel for the tape is defined between the wheels and a mechanism is provided for feeding the tape along the path of travel. A mechanism is provided for applying pressure to the deformable arms for causing the desired imprinting of characters. A lever is pivotally mounted for operating the tape feeding mechanism and the pressure applying mechanism. An arm is mounted on and extends from the lever and the arm includes an end portion which is remote from the mounting position thereof on the lever. A guide element is carried on the end portion. A closed track, having an initial portion and a later portion, is provided in the body of the labeling device and is constructed and arranged to receive and guide the guide element therein. The tape feeding mechanism includes a sprocket wheel which drivably engages the tape.

Abstract: The claimed improved drive means for a rotary internal combustion engine includes means for connecting the piston drive rod to the output drive shaft of the engine which defines a moment arm of variable length for rotating the output drive shaft.
