Abstract

1,126,827. Pipe joints; junction pieces; stopping pipes. MUELLER CO. 19 Nov., 1966, No. 57412/67. Divided out of 1,126,826. Headings F2G and F2P. A gas meter installation is identical to that described in the parent Specification but the claims are directed towards the tamper proof plug which has a wedge shaped end 75 and an internally threaded bore 81. A shaft of the plug extracting tool has a threaded end which engages the bore 81 and the wedge shaped end of the plug is located in a similarly shaped groove in the end of the tool so that the plug may be withdrawn from the port in the inlet valve.
