Abstract
Abstract Disclosed is an apparatus for connecting a service line at a right angle to a main, having a fitting with one end shaped to be fixed to the exterior surface of the main in a plane with the fitting extending horizontally from the main. First and second through bores are formed in the fitting. These bores are axially spaced and positioned in the fitting to radially extend from the main when the fitting is fixed thereto. A port adjacent the end of the fitting shaped for connection to the exterior of the main interconnects the two through bores. Means is provided in the first through bore for connecting a service line to the fitting to extend radially from the center of the main. Internal threads are formed in the second through bore for receiving an externally-threaded tapping means for manipulation axially through the bore to cut a coupon from the wall of the main to interconnect the main with the first through bore. A sealing plug is provided for sealing the open end of the second through bore.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
146 words
An apparatus for connecting a service line at a right angle to a cylindrical main, comprising a fitting having a concave mounting surface formed on one end thereof, said mounting surface conforming with the exterior surface of said main, first and second parallel spaced through bores extending from said mounting surface through the length of said fitting to the opposite end thereof, said first and second bores having their center lines in a plane with the center line of said concave surface and with the center lines of said bores extending at right angles to the center line of said concave surface; means in said fitting interconnecting said first and second bores, means for connecting a service line in said first bore to extend axially from said first bore, and means in said second bore for receiving a means for forming a port in said main.
Claim 2
Independent Claim
146 words
