North Dakota Patent of the Month – September 2021

Bit breakers are devices used in the oil and gas industries to connect and disconnect the joints between pipes or drill bits and other tools. Certain designs for bit breakers are known to become deformed after repeated use. These deformations are quite specific and are termed a “mushroom effect” in the field and can eventually make the piece useless. Falcon Tools, LLC has redesigned these bit breakers to reduce this deformation.

Their bit breaker uses a plate binding a pipe slot with two jaws. These jaws are replaceable, so, once damaged, they can be removed and set with new jaws. To ease the use of a bit breaker, it is designed with an adjustable arm that can be “closed” or “opened”. When closed, the pipe slot is surrounded fully by the bit breaker. When opened, the pipe slot has an open side that makes it easy to remove the bit breaker. The bit breaker is implemented like a usual bit breaker, spun on and held with screw-like threads. The strength attributed to this design allows the but breaker to withstand a rotational force greater than 20, 000 pounds.
