Abstract
1,190,860. Valves. MUELLER CO. 5 Nov., 1968, No. 52435/68. Heading F2V. Valve particularly for use as a " corporation stop," i.e. for connecting an industrial or residential gas or water service line to a street main, comprises a body 10 with a through bore and a lateral boss 24 which accommodates a movable stopper 42 preferably of rubber or like resilient material carried by a screwed plug 34 e.g. of brass or rigid plastics. In order to extend the effective length of the boss, so that a body of maximum through bore can be installed by a tapping and installing machine of a given barrel size, the valve further comprises a cap-like washer 64, preferably of polyethylene. This washer has an integral skirt 66 which engages the rim of the boss and constitutes an extension thereof. The washer is retained in a screwed cap 52 by a snap-in extension sleeve 72 which provides access for an operating tool to engage in the plug. The stopper is retracted fully into the boss in open position; it may be slightly less in diameter than the internal diameter of the thread 30, or may be an interference fit with the thread. The skirt 66 may be initially smooth bored and have a tread cut in it by the plug.
