Abstract: A bat wing for a shuttle car includes a top plate, a lower plate and at least one shieve wheel positioned between the top plate and the lower plate for spacing the top plate a predetermined distance from the lower plate. The lower plate includes at least a first edge, second edge and third edge substantially contiguous to each other and forming the lower plate having a predetermined area. The first and second edges of the lower plate forming a lower edge spaced a predetermined distance from the at least one shieve wheel. The top plate includes at least a first edge, second edge and third edge substantially contiguous to each other and forming the top plate having a predetermined area being greater than the predetermined area of the lower plate. The first and second edges of the top plate forming a top edge spaced a predetermined distance from the at least one shieve wheel and extending outwardly therefrom a distance greater than the predetermined distance of the lower edge from the at least one shieve wheel.
Abstract: A multi-function control actuating mechanism for a roof drilling and bolting machine includes an actuating rod having a first end and a second end. The actuating rod is of a predetermined length and is mounted for movement in a longitudinal direction. A sleeve includes a first end and a second end. The sleeve is mounted for limited rotational movement and is positioned around the actuating rod and extends along a portion of the length thereof. A first bracket is secured adjacent to a first end of the sleeve. A second bracket is secured adjacent to a second end of the sleeve. An actuating lever is operatively connected to the second bracket and to a second end of the actuating rod.
