Abstract
Abstract A saddle component for use when making connections at intermediate points on installed or uninterrupted main lines. The saddle provides an inner stub for extension through a cut hole in the main line and a flange receptacle thereabove for reception of a branch line pipe. A downwardly extending skirt provides with said stub a recess for seal materials. The skirt is marked to facilitate fabrication of efficient transition shapes adapting the saddle for use on various size main lines. A diaphragm section separates the flange from said stub and skirt and provides a flat shoulder for mating contact with the end of the branch line pipe. Openings through the diaphragm section provide access to said seal recess to facilitate placement of seal materials in the recess.

Claim 1
Independent Claim
218 words
A pipe saddle for use when making branch line connections to a main line at random locations therealong comprising a body of generally cylindrical exterior configuration, a diaphragm segment having a flat upwardly disposed surface positioned therein dividing said body into an outwardly opening flange for reception of said branch lines and an inwardly opening skirt section for engagement against exterior surfaces of the main line, and a cylindrical pipe stub of length for extension through the walls of said main line and disposed within said skirt section intercepting said diaphragm Segment to provide an interconnecting flow passage from said flange through said stub, said stub having an inner diameter less than the inner diameter of said flange thereby providing a shoulder at said diaphragm segment and said stub having an outer diameter of lesser size than the inner diameter of said flange whereby said skirt and stub are spaced apart providing an inwardly disposed recess for the reception of seal materials when the pipe stub is inserted through an opening in said main line, said diaphragm section further providing openings through a portion of the flat upwardly disposed surface of said diaphragm to facilitate introduction of seal materials, said openings communicating with said recess from positions that will be closed off when a branch line is installed.

Claim 3
Dependent Claim
120 words
The pipe saddle as set forth in claim 1 and further comprising contour markings on said skirt providing trim lines to which the skirt is cut for mating conformance with the exterior surface of main lines of varying size and thickness wherein the positioning of said contour markings and the length of said pipe stub is regulated in accordance with the contour of the exterior surface of said main lines and the wall thickness thereof whereby the downward end of said pipe stub extends through the cut opening in said main line to a location coinciding with a chord line across the inner circumference of said main line drawn from the lateral ends of the cut provided for said stub.
