Abstract
Abstract A mineral mining installation composed of a conveyor with a guide member for a plough on one side. The position of the guide member in relation to the floor of a mine working is controlled by means of beams connected to the goaf side of the conveyor. In one construction each beam is pivotably connected to the arms of a U-shaped bracket connected to the conveyor and a locking pin is insertable into various alignable bores in the beam and the arms of the bracket in order to secure the beam in various angular positions. In another construction each beam is composed of a channel member rigidly affixed to a leaf spring. The channel member is connected in the manner of a toggle linkage with a plate affixed to the goaf side of the conveyor and a piston and cylinder unit is connected between the channel member and the plate to effect a change in angular position.
