Abstract: A thumb for a machine implement has first and second side plates having a pivot end for pivotally connecting to a linkage of the machine and an engagement end for engaging with a load. A belly plate extends across a width of the thumb between the first and second side plates and along a length of the thumb from the pivot end toward the engagement end. A yoke assembly mounted to a surface of the belly plate is configured to connect the thumb to a thumb actuator that pivots the thumb about the pivot end. A first yoke plate has a first opening and a second yoke plate opposing the first yoke plate has a second opening aligned with the first opening. First and second inner collar spacers are respectively mounted to inner surfaces of the first and second yoke plates aligned with the first and second openings.

Abstract: A tool coupler for coupling a tool to an end of a machine link. The tool coupler having a coupler frame, a hook configured to receive a first pin of the tool and configured to attach to the end of the machine link such that the tool coupler, a wedge slidingly received within the coupler frame, and an actuator connected to the wedge to move the wedge away from the hook to bias a second pin of the tool against the coupler frame. The tool coupler mounts the tool to the machine link such that the tool and the tool coupler pivots about the same axis.

Abstract: A tool coupler assembly may include a power linkage assembly, and the power linkage assembly may include a first power link. The first power link may include a first end configured for pivotal connection to a tool, and a second, opposite end configured for pivotal connection to one end of a tool control actuator. The tool control actuator may be connected at an opposite end to a first end of a tool support member of a machine, wherein operation of the tool control actuator pivots the tool about a tool pivot axis coaxial with a tool engagement interface at a second end of the tool support member. A power linkage actuator may be pivotally connected at a first end for coaxial rotation with the tool engagement interface at the second end of the tool support member, and at a second end for coaxial rotation with the first end of the first power link.

Abstract: One embodiment of a thumb for an implement of a machine has first and second side plates each having a pivot end for pivotally connecting to a linkage of the machine and an engagement end for engaging with a load. The thumb also has a belly plate extending across a width of the thumb between the first and second side plates and extending along a length of the thumb from the pivot end toward the engagement end. Additionally, the thumb has a thumb support structure disposed closer to the engagement end than to the pivot end. The thumb support structure has a first support plate extending widthwise between the first and second side plates and a second support plate extending widthwise between the first and second side plates and further extending between the first support plate and the belly plate.
