ABSTRACT:
A mated pair of sleeper bars (34) comprises a first bar (25) having one end (28') thereof notched to form two fingers (29') and three slots (31'), while one end of the second bar (25) is notched to form three (29) fingers and two slots (31), with the fingers (29) of one bar (25) adapted to fit within the slots (31') of the other bar (25'). The mating fingers (29 and 29') and slots (31 and 31') are drilled for insertion of a connecting pin (37) for pivotally locking the matched ends (28 and 28') of the sleeper bars (25 and 25') together. A plurality of compartments (42) are formed along the length of each sleeper bar (25 and 25'), each compartment (42) being adapted to receive and hold a container (44) filled with a fluid material.
