Meter ring

Claim 2

Meter ring, comprising: (a) a band in the form of a thin sheet metal loop adapted to embrace an annular meter flange, said band having an intermediate portion provided with a weakened tear tab with a gripping finger for bringing about a tearing of the tab and a separation of the loop, (b) a housing permanently attached to one end of the band, the housing being formed with an inner chamber and with a passage leading into it, the other end of the band being formed with an apertured tongue adapted to extend into the passage, and (c) a locking member residing in the chamber and having a finger extending laterally for engagement with the aperture in the tongue, the locking member including resilient means biasing the finger toward the tongue and preventing retraction of the finger from the aperture.

Claim 3

Meter ring as recited in claim 1, wherein the tear tab includes a centrally-located aperture in the band and two weakened tear lines extending at an angle to each other and leading from the aperture to the edge of the band, the grasping finger being integral with the band material between the tear lines and extending generally outwardly of the band.

Claim 4

Meter ring as recited in claim 2, wherein the locking member is in the form of a resilient metal clip having two plate-like legs in spaced, parallel relationship and joined at one end by a bight and providing an opening at the other end to lie adjacent the passage in the housing to receive the tongue between them.

Claim 5

Meter ring as recited in claim 3, wherein the bight of the locking member acts as the resilient means to bias the legs toward one another to embrace the tongue.

Claim 6

Meter ring as recited in claim 4, wherein one of the legs is formed with a lip extending away from the other leg to assist entry of the tongue between the legs.

Claim 7

Meter ring as recited in claim 4, wherein each of the legs is provided with a series of integral fingers inclined away from the passage entering the housing and adapted to slide along the surface of the tongue as it passes between the legs, one of the fingers entering and residing in the aperture in the tongue.

Claim 8

Meter ring as recited in claim 4, wherein the housing has integral pins lying in the bight of the locking member to locate it in the housing and to give it a limited pivotal action.

Claim 9

Meter ring as recited in claim 7, wherein the housing has a bottom wall, two side walls, and two end walls, the passage being formed in one of the end walls, the integral pins being formed from the side walls at a position adjacent the other end wall.

Claim 10

Meter ring comprising: (a) a band in the form of a loop adapted to embrace an annular meter flange, (b) a housing permanently attached to one end of the band, the housing being formed with an inner chamber and with a passage leading into it, the other end of the band being formed with an aperture tongue adapted to extend into the passage, and (c) a locking member residing in the chamber and comprising a metal clip having two plate-like legs in spaced, parallel relationship, and joined at one end by a resilient bight which biases the legs toward one another, said legs providing an opening at the other end to lie adjacent the passage in the housing to receive the tongue between them, at least one of said legs having a relatively rigid finger extending at an angle toward the other leg and away from said opening for engagement with the aperture in the tongue to allow insertion of said tongue between said legs and to prevent retraction of the tongues from between said legs, the housing having integral pins lying in the bight of the locking member to locate it in the housing and to give it a limited pivotal action.

Claim 11

Meter ring comprising: (a) a band in the form of a loop adapted to embrace an annular meter flange, (b) a housing permanently attached to one end of the band, the housing being formed with an inner chamber and with a passage leading into it, the other end of the band being formed with an aperture tongue adapted to extend into the passage, and (c) a locking member residing in the chamber and comprising a metal clip having two plate-like legs in spaced, parallel relationship, and joined at one end by a resilient bight which biases the legs toward one another, said legs providing an opening at the other end to lie adjacent the passage in the housing to receive the tongue between them, at least one of said legs having a relatively rigid finger extending at an angle toward the other leg and away from said opening for engagement with the aperture in the tongue to allow insertion of said tongue between said legs and to prevent retraction of the tongues from between said legs, the housing having integral pins lying in the bight of the locking member to locate it in the housing and to give it a limited pivotal action.

Claim 12

Meter ring as recited in claim 9, wherein one of the legs is formed with a lip extending away from the other leg to assist entry of the tongue between the legs.

Claim 13

Meter rings as recited in claim 9, wherein each of the legs is provided with a series of integral fingers inclined away from the passage entering the housing.

Claim 14

Meter ring as recited in claim 9, wherein the housing has a bottom wall, two side walls, and two end walls, the passage being formed in one of the end walls, the integral pins being formed from the side walls at a position adjacent the other end wall.

Claim 15

Meter ring comprising: (a) a band in the form of a loop adapted to embrace an annular meter flange, (b) a housing permanently attached to one end of the band, the housing being formed with an inner chamber and with a passage leading into it, the other end of the band being formed with a tongue having laterally extending notches and adapted to extend into the passage, and (c) a locking member residing in the chamber and comprising a metal clip having two plate-like legs in parallel relationship, and joined at one end by a resilient bight which is anchored in the housing and which biases the legs toward one another and in engagement with one another, at least one of said legs having a lip at the other end which extends away from the other leg to form an opening adjacent the passage in the housing to receive the tongue between them, at least one of said legs having a relatively rigid finger extending at an acute angle toward said bight to allow insertion of said tongue between said legs, and to engage one of said notches to prevent retraction of the tongue from between said legs, to lock the tongue, the clip and the housing together.

Claim 16

Meter ring comprising: (a) a band in the form of a loop adapted to embrace an annular meter flange, (b) a housing permanently attached to one end of the band, the housing being formed with an inner chamber and with a passage leading into it, the other end of the band being formed with a tongue having laterally extending notches and adapted to extend into the passage, and (c) a locking member residing in the chamber and comprising a metal clip having two plate-like legs in parallel relationship, and joined at one end by a resilient bight which is anchored in the housing and which biases the legs toward one another and in engagement with one another, at least one of said legs having a lip at the other end which extends away from the other leg to form an opening adjacent the passage in the housing to receive the tongue between them, at least one of said legs having a relatively rigid finger extending at an acute angle toward said bight to allow insertion of said tongue between said legs, and to engage one of said notches to prevent retraction of the tongue from between said legs, to lock the tongue, the clip and the housing together.

Claim 17

Meter ring as recited in claim 1, wherein the band has a U-shaped cross-section with the legs directed inwardly of the loop.
