Abstract
ABSTRACT OF THE DISCLOSURE
A cover assembly for a meter socket. The assembly comprises a circular disc formed of a single piece of molded insulating material. The disc has a diameter and an edge thickness substantially equal to that of a retaining ring of a meter intended for assembly into the socket. The disc has cavities molded into the rear surface thereof with the cavities opening to the rear surface only. Conductive jumper members are mounted on the rear side of the disc by fasteners engaged with the walls of the cavities without protruding from the front of the disc.

Description
1:~763 BACKGROUND OF T~IE I~VE~TIO~
In electric power distribution, meters for measuring power consumption are customarily provided with rearwardly extending contact blades for insertion into and frictional engagement with a meter socket having spring jaw connectorsO
The meter is held in place by a meter ring which clamps a meter flange to a support member associated with the meter socket, or by a cover plate having an aperture receiving the meter housing, the periphery of which covers the meter flange.
In situations where it is necessary to provide tempor-ary power without a meter in the meter socket, or where it is desired to bypass the meter socket, it is necessary to provide ~umper means for connecting the live terminals of the meter socket to the load terminals thereof.
Although it has been possible to do this with jumper cables or connectors, this procedure could leave the contacts exposed to the weather and also susceptible to accidental or intentional contact by unauthorized personnel.
SUMMARY OF TI~E INVENTION
A me-ter socket jumper comprises a plastic disc having a diameter and a peripheral thickness the same dimensions as the retaining ring of a meter designed for assembly into said socket. The disc has integrally molded pockets opening to the rear or inside face of the disc only, said pockets being dimensioned to receive self tapping screws to allow attachment of a conductive jumper to the rear face of the disc.
The molded pockets protrude forwardly from the front face of the disc, and stiffening webs intersect the pockets to strengthen them against expansion and lateral movement when a screw is assembled therein.
A plurality of pockets are provided at predeter~
mined positions on the disc to allow assembly of jumpers at different positions to allow the device to be used with meter sockets of various types.
The jumpers are provided with contact blades for assembly into the jaw contacts of the meter socket, thereby retaining the device in position until the meter box cover is closed, or until a retaining ring is assembled, depending on the type of meter socket.
According to a broad aspect of the present invention there is;provided a cover for a meter socket adapted to receive jumpers for completing a circuit between meter socket terminals. The cover comprises a disc formed ., i~63 of insulating material. The disc has a peripheral flange having a diameter and thickness substantially the same as that of a retaining flange of a meter intended for assembly into the meter socket. A central portion is~also provided and substantially thinner than the width of the flange.
A series of cylindrical walls extends from the central portion. These walls are closed at the forward end on the forward side of the disc and open at the other end on the rear side of the disc forming a pocket. The walls are dimensioned to receive a fastening device from the réar side for attachment of a jumper without exposure of the fastening device on the forward side of the disc.

DESCRIPTION OF THE_ILLUSTRATED EMBOD~MENT
Referring to the drawing, there is illustrated a meter socket jumper 10 intended for assembly with a meter socket 12, which comprises a plastic disc 14 and metallic jumpers 16 assembled onto the rear side thereof.
The disc 14 is circular in shape, with a diameter the same as that of a meter designed for assembly into said socket, and a peripheral flange 18 which has a width sub-stantially the same as that of the flange on said meter so that the meter socket jumper assembly 10 may be assembled with a meter socket and be retained therein in the same manner as a meter as will be described more fully herein-after.
The main body of the disc 14 is relatively thin, with a series of reinforcing ribs 20 formed on the forward face thereof. Intersecting the reinforcing ribs are a series of molded cylindrical walls 22 which extend from the forward face of the disc. Said walls are open at the rear end at the rear face of the disc but are closed on the forward end which protrudes from the forward side of the disc, forming pockets 24 which open to the rear side of the disc.
The pockets 24 have a diameter and depth appropriate for receiving self-tapping screws 26 for attaching the con-ductive jumpers 16 to the rear side of the disc.
The jumpers 16 each comprise a pair of contact blades 30 and a connecting bar 32. The bar 32 is secured to the disc by the screws 26 seated in pockets 24.
In the usual case a pair of jumpers 16 are attached to the rear side of the disc, with the blades being spaced and dimensioned to be frictionally engageable with jaw contacts 34 in the meter socket, in the same manner as a meter.
~L~ 3 The meter socket jumper assembly may therefore be assembled into the meter socke~ in the same manner as a meter, with the jumpers 28 completing a circuit from the live contact jaws to the load contact jaws. The assembly is retained in the meter socket initially by frictional engagement of the blades 30 in the socket jaws, and then by a cover plate 36 having a central aperture 38 which nor-mally receives a meter housing. Since the periphery of the disc 14 has the same diameter and thickness as that of the retaining ring of a meter, the -flange 18 is positioned in the meter socket by meter positioning flanges 40 and re-tained in the socket by the cover plate.
To facilitate insertion and removal of the assembly, a handle 42 may be attached by self-tapping screws to the forward face of the disc.
As illustrated in the drawing, a plurality of pockets may be provided opening to the rear face of the disc, so that jumpers may be assembled in different positions to allow the device to be used with sockets of different

2~ spacing and numbers of jaw contacts.
The pockets in the disc allow secure assembly of the jumpers onto the rear side of the disc, without exposure of any voltage carrying components on the front face of the disc, thus eliminating any possibility of electrical shock.
Although in the illustrated embodiment of the inven-tion the disc is formed of transparent plastic, it may be formed of opaque material if desired.
Since certain changes apparent to one skilled in the art may be made in the herein illustrated and described em-bodiment of the invention without departing from the scope thereof, it is intended that all matter contained herein be interpreted in an illustrative and not a limiting sense.
