Abstract: Apparatus for attaching conveyor chains and flights utilized in shuttle cars are disclosed. The flight attachment design includes an attachment link with male members extending from the roller links to which the flights are to be attached. The roller links have slots which allow the engagement of each of the roller links by the drive sprockets. A specially designed flight has female receptacle with inwardly tapered ends which are positioned around the male extensions of the roller links. Retaining pins inserted in cooperating holes secure each of the flights to the male members of the roller links. The roller links of each conveyor chain are connected by side plates and pins positioned on each side of the roller link such that a slot remains between the roller links which may be engaged by the drive sprockets.

Abstract: A cutter bit holding assembly is disclosed. The cutter bit assembly contains a cutter bit having a shank portion and a cutter bit holder having a socket for receiving the cutter bit shank portion. Also included is a rotary locking element which is associated with the cutter bit holder and a bore adjacent the socket. The bore runs in a direction parallel the direction in which the bit holder cuts. The locking element has an offset locking portion which cooperates with an indented locking surface on the bit shank. The rotary locking element is capable of being rotated completely out of the socket bore and out of engagement with the bit shank locking surface to permit the unencumbered removal or insertion of a bit. An elastomeric element inserted along part of the bore in the cutter bit holder is utilized to prevent rotation of the locking element out of engagement with the bit shank locking surface during operation of the cutting device.
