Multifunction register enclosure for energy meter
First Claim
1. An electric energy meter including a watthour meter utilizing an eddy current disk rotating in response to energy consumed by the load being metered and including a power integrating and indicating means positioned substantially on one side of the eddy current disk, an electronic register assembly to provide time of use or demand energy readings configured to be selectively added within the electric energy meter on the other side of the eddy current disk comprising:
- a disk sensing optics assembly including one or more pairs of light emitters and light detectors positioned on either side of a castellated shutter which is coupled to, and rotates with, said eddy current disk;
said disk sensing optics assembly being positioned on a register circuit board;
a register enclosure configured for mounting on the other side of said eddy current disk beside said power integration and indicating means;
said register circuit board being mounted on mounting means integral with said register enclosure;
a display positioned at one end of said register enclosure through display positioning means integral with said register enclosure;
said register enclosure further including integral members for supporting and positioning other components of said electronic register;
said other components including an optical readout assembly for optical communications between said electronic register and the outside of said energy meter;
means to connect said electronic register in circuit with power lines being metered;
circuitry of said electronic register assembly providing energy readings; and
register positioning means integral with said register enclosure to position said electronic register assembly adjacent to said side of said eddy current disk opposite said power integrating and indicating means of said watthour meter.

Abstract
An electronic time of use or demand register is provided for selective addition to a watthour meter in an energy meter. The electronic register is configured for parallel mounting beside the watthour meter to minimize space and includes an integral register enclosure for properly assembling and securing various components in positive operational relationships such as positioning the optical detection assembly relative to the rotating castellated shutter and in turn positioning the optical communications link relative to the optical detection assembly. The register enclosure additionally includes integral means for mounting the electronic register within the energy meter and for selectively adding and positioning a plurality of optional features.
