  • Patent number: 5732781
    Abstract: A mechanism to interfit between the bucket of a front end loader and its support and tilting arms allows the bucket be tilted in a laterally extending vertical plane. The mechanism provides a rear plate, having rearwardly extending fastening structure to pivotally interconnect to the support and tilting arms, pivotally carrying a front plate having forwardly extending fastening structure to immovably interconnect the bucket. The pivotal interconnection of the front plate with the rear plate is accomplished by a medial journaling pin, journaling channels at each lateral end of the rear plate that carry the lateral portions of the front plate and a medial nut and bolt combination extending therebetween to allow limited pivotal motion. A first species of mounting mechanism powers the tilting motion of the bucket by an asymmetrically positioned, horizontally extending hydraulic cylinder, and a second species powers the tilting motion by an asymmetrically positioned, vertically extending hydraulic cylinder.
