Abstract
Abstract The following specification describes a meter receptacle assembly utilizing an outer collar to overlap the meter flange base and latched to the cabinet in which the meter is mounted by interlocked tabs and a sealing wire. A trim or cover plate for the cabinet in turn overlaps a flange wall on the collar and is locked to the cabinet to prevent removal of the collar and unauthorized bypass of the meter. A cutout in the cover plate provides access and visibility for the sealing wire. Authorized bypass connections for the meter to permit its removal without disturbing service are facilitated by horn terminals whose ends project beyond the meter periphery to permit facile connections thereto.

Claim 1
Independent Claim
333 words
A meter receptacle assembly for a meter having a plurality of spaced contact blades extending outwardly from one surface of a flanged base at one end of a meter, said assembly including a cabinet, a plurality of socket receptacles, an insulating plate supported in said cabinet carrying said receptacles in spaced positions to receive a respective contact blade to establish a connection between one receptacle and a respective other receptacle, the improvement comprising: a ring secured to said cabinet and adapted to engage said one surface of said flanged base in response to the receipt of said contact blades by said receptacles, a detachable annular collar removably attached to said cabinet and adapted to overlap said flanged base and ring, said collar having a radially outwardly extending flange wall at one axial end of said annular collar and a radially inwardly extending annular lip at the other axial end of said annular collar for abutment with said flanged base at a position spaced from said one surface, said flange wall extending radially outwardly of said collar and ring and having a passageway, said flange wall encircling said collar, a latch having one end secured to said flange wall and another end axially spaced in a direction opposite said annular lip from said flange wall and extending in one angular direction, a pair of circumferentially spaced tangs on said ring each extending radially outwardly of said ring, one of said tangs adapted to be received between said latch and said flange wall in response to the engagement of said collar with said flanged base and rotation of said collar in said one direction to restrain axial movement of said collar, a fastener extending from the other one of said tangs through said passageway in said flange wall to restrain rotational movement of said collar, and an outer cover plate overlapping said flange wall and secured to said cabinet with said cover plate having a cutout passing said fastener to enable access to said fastener.

A meter receptacle assembly for a meter having a plurality of spaced contact blades extending outwardly from one surface of a flanged base at one end of a meter, said assembly including a cabinet, a plurality of socket receptacles, an insulating plate supported in said cabinet carrying said receptacles in spaced positions to receive a respective contact blade to establish a connection between one receptacle and a respective other receptacle, the improvement comprising: a ring secured to said cabinet and adapted to engage said one surface of said flanged base in response to the receipt of said contact blades by said receptacles, a detachable annular collar removably attached to said cabinet and adapted to overlap said flanged base and ring, said collar having a radially outwardly extending flange wall at one axial end of said annular collar and a radially inwardly extending annular lip at the other axial end of said annular collar for abutment with said flanged base at a position spaced from said one surface, said flange wall extending radially outwardly of said collar and ring and having a passageway, said flange wall encircling said collar, a latch having one end secured to said flange wall and another end axially spaced in a direction opposite said annular lip from said flange wall and extending in one angular direction, a pair of circumferentially spaced tangs on said ring each extending radially outwardly of said ring, one of said tangs adapted to be received between said latch and said flange wall in response to the engagement of said collar with said flanged base and rotation of said collar in said one direction to restrain axial movement of said collar, a fastener extending from the other one of said tangs through said passageway in said flange wall to restrain rotational movement of said collar, and an outer cover plate overlapping said flange wall and secured to said cabinet with said cover plate having a cutout passing said fastener to enable access to said fastener.
Claim 3
Dependent Claim
122 words
In the assembly claimed in claim 1 a plurality of terminals each connected to a respective receptacle and fixed to said plate, each terminal extending to a respective position located radially outward of a respective edge of said insulating plate and having a V shaped tab with one leg of said tab extending axially from said ring in overlapping relationship to said plate and the other leg of said tab forming a free end prong spaced radially outwardly of said ring and extending axially toward said ring for enabling the extension of a bypass electrical connection for said meter in response to the disengagement of said collar from said ring and irrespective of the engagement of said flanged base with said ring.
Claim 4
Dependent Claim
29 words
In the assembly claimed in claim 1 an offset portion on said flange wall forming a passage, and a closed sealing wire loop extending through said passage and fastener.
Claim 5
Dependent Claim
58 words
The assembly claimed in claim 3 in which a plurality of insulating plates each having socket receptacles are carried in said cabinet with each plate having a respective meter, ring, collar and securing means, the improvement comprising a single cover plate having a plurality of spaced cutouts each aligned with a respective fastener, sealing wire and offset portion.
Claim 6
Dependent Claim
209 words
A meter receptacle assembly for a meter having a plurality of spaced contact blades extending outwardly from one surface of a flanged base at one end of said meter, said assembly including a cabinet, a plurality of socket receptacles, an insulating plate supported in said cabinet carrying said receptacles in spaced positions to receive a respective contact blade to establish a connection between one receptacle and a respective other receptacle, the improvement comprising: a ring secured to said cabinet adapted to engage said flanged base in response to the receipt of said contact blades by said receptacles, a plurality of terminals each secured to said insulating plate and to a respective socket receptacle in electrical engagement with a respective receptacle, each terminal extending to a respective position spaced radially outwardly of a respective edge of said insulating plate and having a V shaped tab with one leg of said V shaped tab extending axially from said ring in overlapping relationship to said plate and the other leg of said V shaped tab forming a free end prong extending axially toward said ring and spaced radially outwardly of said ring to provide a bypass electrical connection for said meter irrespective of the engagement of said flanged base with said ring.
Claim 7
Dependent Claim
209 words
A meter receptacle assembly for a meter having a plurality of spaced contact blades extending outwardly from one surface of a flanged base at one end of said meter, said assembly including a cabinet, a plurality of socket receptacles, an insulating plate supported in said cabinet carrying said receptacles in spaced positions to receive a respective contact blade to establish a connection between one receptacle and a respective other receptacle, the improvement comprising: a ring secured to said cabinet adapted to engage said flanged base in response to the receipt of said contact blades by said receptacles, a plurality of terminals each secured to said insulating plate and to a respective socket receptacle in electrical engagement with a respective receptacle, each terminal extending to a respective position spaced radially outwardly of a respective edge of said insulating plate and having a V shaped tab with one leg of said V shaped tab extending axially from said ring in overlapping relationship to said plate and the other leg of said V shaped tab forming a free end prong extending axially toward said ring and spaced radially outwardly of said ring to provide a bypass electrical connection for said meter irrespective of the engagement of said flanged base with said ring.
