摘要： A blade housing assembly for a power operated rotary knife including a split blade housing and an expansion sleeve assembly. The split blade housing including an annular blade support section and a mounting section extending from the blade support section. The mounting section includes a split extending through the mounting section and includes a first body portion and a second body portion on opposite sides of the split, the first body portion including a slot extending axially through the first body portion and movable between blade supporting and blade changing positions. The expansion sleeve assembly extends through the slot and includes a split sleeve changeable between first and second circumferences. The expansion sleeve assembly further including a fastener extends through the split sleeve and, when engaged with the split sleeve, maintains the split sleeve in the first circumference and secures the first body portion in the blade supporting position.

摘要： A power operated rotary knife including an annular rotary knife blade supported for rotation in a blade housing. The rotary knife blade including a body and a blade section extending from the body. The body includes an outer wall including an arcuate surface having an upper region extending from a first upper end portion to a second intermediate portion and a lower region extending from the second intermediate portion to a third lower end portion. A plurality of gear teeth extend downwardly from the upper end of the body, each of the plurality of gear teeth including an outer peripheral face forming a portion of the upper region of the arcuate surface of the outer wall. The body outer wall includes a bearing surface having a lower bearing face in the lower region of the arcuate surface and an upper bearing face in the upper region of the arcuate surface.

摘要： A blade housing assembly for a power operated rotary knife including a split blade housing and a cam mechanism for changing a blade housing diameter between blade supporting and blade changing positions. The split blade housing includes an annular blade support section, a mounting section and a split extending through the mounting section and an inner wall of the blade support section and defining a split distance between first and second circumferential ends of the inner wall. The split includes a radial split section and an angled split section adjacent the inner wall. The mounting section includes first and second body portions on opposite sides of the split. The cam mechanism includes a cam plate bridging the first and second body portions and a cam member rotatably supported by the cam plate. The cam member is rotatable between closed and open positions to change the blade housing diameter.

摘要： A rotary knife includes a frame, an annular blade, and a blade housing mounted to the frame. The housing presents a circumferential mounting surface in contact with the frame. The housing supports the blade on the frame for rotation about a central axis. The housing includes a blade-supporting race defined along a circle centered on the central axis. The mounting surface is defined along a circular arc with a center point spaced from the central axis, such that the blade-supporting race and mounting surface are eccentric relative to one another. The housing presents opposite inner and outer annular faces. At least one of the faces presents a proximal-most end in contact with the frame and a distal-most end spaced from the frame. The proximal-most end is spaced from the central axis a first distance. The distal-most end is spaced from the central axis a second distance. The distances are different.

摘要： A chicken skinning handheld kitchen tool of a unitary structure is provided. In some embodiments, the present invention may provide for conically shaped kitchen tool with a ridged base member and a top member having teeth or tine extending therefrom and curving downward at a variable angle of 45 to 90 degrees. The present invention may be made from a thermoplastic polymer that is sufficiently rigid to withstand forces that would normally be applied without breaking and sufficiently flexible so that it will flex during operation.
