Patent number: 11654589Abstract: A power operated rotary knife assembly including a power operated rotary knife having an annular rotary knife blade, a trim guide, and a drive mechanism for driving the rotary knife blade about an axis of rotation. The assembly also includes a portable power unit, a vacuum assembly and a flexible shaft drive transmission coupled between the power operated rotary knife and the portable power unit. The portable power unit includes a drive motor assembly providing a rotational power source which is operatively coupled to the drive mechanism through the flexible drive transmission to rotate the rotary knife blade. The portable power unit also includes a blower assembly providing vacuum pressure at an inlet duct side, the vacuum assembly being in fluid communication with the inlet duct side to generate a vacuum pressure condition in a region of a cutting opening defined by the rotary knife blade and the trim guide.Type: GrantFiled: March 3, 2020Date of Patent: May 23, 2023Assignee: Bettcher Industries, Inc.Inventors: Joel L. Hall, Terrence A. Pagano, Kevin V. Stump

Patent number: 9908253Abstract: A power operated rotary knife including: a handle assembly, a head assembly and a vacuum attachment assembly. The handle assembly includes an elongated cylindrical handle housing defining a handle assembly longitudinal axis extending through a throughbore of the handle housing. The head assembly includes a rotary knife blade rotatably supported for rotation about an axis of rotation in a blade housing and a frame securing the blade housing to the distal end of the handle assembly in a position offset from the handle housing, the axis of rotation of the rotary knife blade being spaced apart from and parallel to the handle longitudinal axis. The vacuum attachment assembly includes an adapter extending at an angle away from the handle housing such that a central axis of the adapter is transverse to the with respect to the rotary knife blade axis of rotation and the handle assembly longitudinal axis.Type: GrantFiled: September 19, 2016Date of Patent: March 6, 2018Assignee: Bettcher Industries, Inc.Inventors: Nicholas A.
