Abstract
A linkage and motion system pivoted to a bracket comprises a first linkage connecting the bracket with a second linkage, a holder connected to the bracket and to the second linkage, and a drive with a linear working motion connected to the bracket. The articulated connection of the drive to the bracket is spaced from that of the holder thereto, the articulated connections of the second linkage to the holder, the first linkage and the drive define a triangle, and the articulated connection of the first linkage to the bracket and that of the drive thereto are on either side of the articulated connection of the holder to the bracket.
Claims7
A linkage and motion system especially for oscillating equipment such as buckets to excavators and the like, the equipment or its attachment being pivotably attached to a holder, characterized by a first linkage device connecting said attachment with a second linkage device which in turn is articulately joined to said holder, between said second linkage device and said attachment there being articulately attached a driving means with a linear working motion, said driving means being articulately attached to the attachment at a point at a distance from the articulation points of the holder to the attachment, the articulation points of said second linkage device being so situated that they geometrically form the corner points in a triangle, the articulation points for said first linkage means at the attachment and the articulation points for the driving means at the attachment being on either side of the articulation point of the attachment to the holder.
