Description

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to plumbing apparatuses, and more particularly, to a universal water meter connector assembly that is configured to be connected with different sized water meter couplers.

2. Description of the Prior Art

A water meter is connected to a supply line for a dwelling by means of a water meter connector. The water meter is provided with a meter coupler. The water meter connector couples the water meter coupler to the dwelling supply line. Since water meter couplers come in various sizes, for example, one inch and three-fourths of an inch, a plumber must carry different sized water meter connectors. Also, it is to be noted that a dwelling supply line can be made of a variety of materials from flexible tubing composed of a polymer or copper, for example, and rigid pipes. Since different sized water meter couplers and various dwelling supply lines are used, a plumber must carry a large number of meter connectors to cover the multitude of different combinations of meter coupler size and dwelling line material. That is, the plumber must carry meter connectors that are sized to fit the particular water meter coupler at the site. Also, the plumber must carry water meter connectors that are configured to interconnect with the particular dwelling supply line. A need has arisen for a relatively simple and inexpensive water meter connector assembly that can be used with different sized water meter couplers and a variety of dwelling supply lines.

The present invention features a universal water meter connector assembly that is configured to be used with different sized water meter couplers and a variety of dwelling supply lines. The universal water meter connector assembly embodying the invention includes a hexagonal body that terminates in an externally threaded head at one end. The hexagonal body is provided with an internally threaded medial portion and an internally threaded end portion at an end of the hexagonal body. The thread size of the internally threaded medial portion is smaller than the thread size of the internally threaded end portion. The free end of the head is formed with an internally tapered portion that is configured to receive a cone-shaped member having a narrow end and a wide end with a beveled rim. The narrow end of the cone member is sized and shaped to mate with the internally tapered portion of the head. A gripper ring with depending fingers is positioned on the beveled rim of the cone-shaped member. A connector nut is formed with an internally threaded portion that is sized to be threaded onto the externally threaded head. An internal flange at an upper end of the connector nut engages the gripper ring and urges it against the cone-shaped member and the cone-shaped member is urged into the tapered portion of the head when the connector nut is turned onto the externally threaded head.
