Abstract:
1. Article breaking apparatus, the apparatus including: a first member having a first jaw on an end thereof, the first jaw having a first article supporting surface, the first member including a first pivot means and a fixing means remote from the first jaw for permitting mounting of the apparatus on a vehicle arm, a second member pivotally mounted on the first pivot means about a first pivot axis and having a second jaw cooperable with the first jaw, the second jaw having an article engaging surface and being movable about the first pivot axis relative to the first jaw in an article receiving position in which the first article supporting surface and the article engaging surface diverge away from the first pivot axis, and an article breaking position in which said surfaces diverge towards the first pivot axis, whereby, as the second jaw moves from the receiving position to the breaking position, an article located between the jaws will be urged along the first article supporting surface towards the first pivot axis by the movement of the second jaw against the article relative to the first jaw, said apparatus further including means for moving said jaws between the receiving and breaking positions, the means for moving comprising a piston and cylinder assembly mounted on said first member, the piston and cylinder assembly is driven by a hydraulic compressor of the vehicle to which the apparatus is attached in use, the cylinder of the piston and cylinder assembly is pivotally mounted on the first member, and the piston is pivotally connected at its end about a second pivot axis to a slot or slots in the second member, the end of the piston includes a pin extending through and slidably mounted in the slot or slots such that initially the pin moves towards the first pivot axis, and subsequently away from said axis, as the jaws move respectively from the receiving position to the article breaking position.
