Abstract

A chassis for a residential utility meter reading unit includes individual chambers including a transmitter chamber containing a printed circuit board, an indexing unit chamber containing the mechanism for operating dials that rotated in response to use of the utility product to indicate the magnitude of consumption, and a battery chamber releasably connected to the chassis and adapted to complete an electrical connection between batteries and circuit board as the third chamber moves relative to the chassis. A transparent cover overlaps a slot formed in the chassis and a leg extending from the battery chamber moveable in the slot. Rails on the chassis block movement of sliders on the battery pack away from the chassis to prevent disengagement of the battery chamber from the chassis unless the cover and its attachment screws are first removed.

Claims

1. A gas utility meter reading unit for producing an indication of the quantity of gas consumed, comprising:

a housing divided into chambers;

a first chamber containing a printed circuit board having a first terminal for connection to an electrical power source;

a second chamber sized to contain and hold at least one battery therein, having a second terminal electrically connectable to said at least one battery, moveable relative to said first chamber, adapted to complete an electrical connection between said first terminal and said second terminal as said second chamber moves relative to said first chamber, and releaseably fixed to said housing; and

a cover overlapping the electrical contact of said first and second chambers, wherein;

said housing defines a first portion having a first free edge around a periphery of said housing, a second portion having a second free edge around a periphery of said housing, said second free edge directed toward said first portion and overlapping said first free edge, and a seal located in a space overlapped by said first and second portions and located near said first and second free edges;

said first portion is formed integrally with multiple first shoulders located within said first portion;

said second portion is formed integrally with multiple second shoulders located within said second portion, said second shoulders directed toward said first shoulders, a thin space being created between said first and second shoulders; and

said printed circuit board having first and second surfaces, said first and second surfaces located between said first and second shoulders, whereby said printed circuit board is held in position inside said housing.
