Abstract
A dual purpose bracket assembly for a horizontal directional drill that retains pipes within a cartridge when the cartridge is detached from the drill and locks the cartridge to the drill when it is attached. The bracket assembly includes side plates that are installed within longitudinal support members. A pivot pin is installed through the side plates and the longitudinal support members and allows the bracket assembly to rotate between a pipe retention position and a locked position. A dual purpose removable pin supports the weight of the pipes in the pipe retention position when the cartridge is detached and locks the cartridge to the drill when the cartridge is attached.
