Yoke for mounting on a gas tank

In combination, a gas tank valve and a yoke for mounting gas passaging structure on the valve,

• the gas tank valve comprising a valve body and a valve stem mounted on the valve body for turning relative to the body in a first direction to open the valve and in a second direction opposite the first to close the valve, the valve stem having a pair of flats on opposite sides of the valve stem adapted to be engaged by a wrench for turning the valve stem, the pair of flats being spaced apart a first distance, and
• the yoke comprising a generally central opening sized and shaped for receiving at least a portion of the valve body therethrough, a set screw adapted to extend through the yoke and threadably engage the yoke, the set screw having an inner end portion capable of engaging the valve body in the central opening of the yoke for releasably mounting the yoke on the valve body, and an outer end portion extending outwardly from the yoke, the outer end portion having a pair of flats on opposite sides of the set screw adapted to be engaged by the wrench for turning the set screw into engagement with the valve body, the flats on the set screw being spaced apart a second distance substantially equal to the first distance by which the flats of the valve stem are spaced apart, whereby the same wrench used for turning the valve stem may be used for turning the set screw, and a torque rod connected to the set screw for conjoint rotational movement with the set screw about the longitudinal axis of the set screw for applying torque to the set screw for turning the set screw to bring it into secure engagement with the gas tank valve thereby to hold the yoke in a fixed, self-retaining position on the valve.
