ABSTRACT:
The drum deheader or cutter is for use in opening an end of a drum provided with a drum chime and comprises a base engageable with the outside surface of the drum, with the base having at one end an upstanding lug engageable with the top of the drum chime and having at the other end a shoulder engageable with the underside of the drum chime. A head is pivotally mounted on the base and is provided with an integral handle which extends in a direction away from said base and the drum. A blade is secured to the head for cutting the end of the drum adjacent the drum chime. An elongated operating lever is pivotally mounted on one end to the base and is connected to the head by a suitable linkage. A person may grip the handle with one hand and apply a force to the lever with the other hand thereby causing the head to pivot and the blade to be lowered into cutting engagement with the end of the drum. The blade is adjustable relative to the base to permit a close cut of drum along the drum chime regardless of the thickness of the drum chime that is between the blade and base.
