A telephone signal or a radio signal is employed to terminate the through flow of gas through a gas meter to enable the flow of gas to a consumer to be terminated from a remote position. In one embodiment, a weighted arm includes a closure member to obturate an opening. The closure member is part of a weighted arm mounted on a rotatable rod bearing a toothed wheel engaged by a pawl which is operated by an electromagnetic arrangement which in turn is controlled by a signal. Provision is made for resetting the arrangement mechanically by the utilization of a key received in the key receiving end of the rotatable rod. In another embodiment, use is made of the fact that the gas meter includes a bellows and rotating arm arrangement. In this embodiment a rod is dropped into a position of interference with the rotating arm thereby to interfere with the flow of gas through the gas meter. In this embodiment resetting is effected by connecting an external power source to an electromagnet within the meter whereby to control the position of the rod which is dropped into interfering position with the rotating arm.
Apparatus comprising a gas meter, inlet pipe means for supplying gas to said gas meter, outlet pipe means for conveying gas away from said gas meter, internal meter means for converying gas from said inlet means to said outlet means, and control means responsive to a signal originating outside of said meter for interfering with the flow of gas through at least one of the first three said means, said control means including displaceable means having a first position of non-interference with any of the first three said means and a second position for interfering with the flow of gas through at least one of the first three said means, said control means further including holding means to hold said displaceable means in said first position and being responsive to said signal for releasing the displaceable means to said second position;
Apparatus comprising a gas meter, inlet pipe means for supplying gas to said gas meter, outlet pipe means for conveying gas away from said gas meter, internal meter means for conveying gas away from said inlet means to said outlet means, and control means responsive to a signal originating outside of said meter for interfering with the flow of gas through at least one of the first three said means, said control means including displaceable means having a first position of non-interference with any of the first three said means and a second position for interfering with the flow of gas through at least one of the first three said means, said control means further including holding means to hold said displaceable means in said first position and being responsive to said signal for releasing the displaceable means to said second position, said control means including a conduit connection to said outlet means, a closure member located over said connection to said outlet means to obturate the same, suspension means to keep said member spaced from said connection, and release means to release said suspension means to enable said closure means to obturate said connection, said suspension means including a rotatable rod, an arm extending generally radially from said rod, a toothed wheel on said rod, a pawl normally in interfering relation with said toothed wheel and electromagnetic means to withdraw said pawl from said interfering relation.
Apparatus comprising a gas meter, inlet pipe means for supplying gas to said gas meter, outlet pipe means for conveying gas away from said gas meter, internal meter means for conveying gas from said inlet means to said outlet means, and control means responsive to a signal originating outside of said meter for interfering with the flow of gas through at least one of the first three said means, said control means including displaceable means having a first position of non-interference with any of the first three said means and a second position for interfering with the flow of gas through at least one of the first three said means, said control means further including holding means to hold said displaceable means in said first position and being responsive to said signal for releasing the displaceable means to said second position, said internal meter means including a bellows and rotating means to meter the flow of gas from the inlet means to the outlet means and said control means including a member to move into interfering position with the rotating means to impede the flow of gas.
Apparatus comprising a gas meter, inlet pipe means for supplying gas to said gas meter, outlet pipe means for conveying gas away from said gas meter, internal meter means for conveying gas from said inlet means to said outlet means, and control means responsive to a signal originating outside of said meter for interfering with the flow of gas through at least one of the first three said means, said control means including displaceable means having a first position of non-interference with any of the first three said means and a second position for interfering with the flow of gas through at least one of the first three said means;
