Abstract
A coupler is provided which is mountable to a fitting of a breakaway coupling to facilitate assembly and disassembly of the coupling. The coupling has a first fitting and a second fitting which are held together by a ball in the first fitting which is received in a detent in the second fitting. The second fitting has an outer sleeve on which the detent is formed, and an inner sleeve slideable in the outer sleeve. A latch ring on the inner sleeve is alignable with the groove. A spring biases the inner sleeve and latch ring into a locking position in which the detent balls are urged into engagement with the detent to hold the two fittings together. The coupler includes an open ended housing having a side wall and an end wall. A plate, securable to the second fitting inner sleeve, is received in the coupler housing for axial movement. A cam on an outer surface of the housing end wall is connected to the plate by a rod. The cam is pivotable between a first position in which its camming surface is out of engagement with the housing end wall and a second position in which its camming surface engages the housing end wall. As the cam is moved to the second position, the plate is pulled toward the housing end wall, thereby pulling the second fitting inner sleeve axially in the outer sleeve against the force of the spring to move the latch ring out of alignment with the groove sufficiently to enable the detent ball to move radially in its associated opening and to disengage the groove.
