ABSTRACT:
The quick coupler anchor includes an anchor body having a pair of vertical plates extending generally at right angles one to the other and spaced from one another. Planes containing the plates, when extended, intersect along a vertical line offset from the center axis of a valve received in a recess in a member connecting upper edges of the vertical extending plates. The recess has a plurality of flats for registration with the flats of the hex nut of the valve body. When the anchor is embedded in the ground with the recess about the hex nut, the anchor restrains rotational movement of the valve relative to the anchor in response to a torque applied to the valve to open or close the valve. The center of vertical support of the anchor lies generally coincident with the vertical axis of the valve to provide stability to the valve and anchor upon vertical loadings.
