Abstract

A mechanical branch outlet including: a housing having an outer surface and an inner surface and defining an outlet bore extending between the outer surface and the inner surface; and an insert having a first end and a second end, the outlet bore of the housing sized to receive the second end of the insert and retain the first end of the insert.

First claim

That which is claimed is:

1 . A mechanical branch outlet comprising:
a housing having an outer surface and an inner surface and defining an outlet bore extending between the outer surface and the inner surface; and an insert having a first end and a second end, the outlet bore of the housing sized to receive the second end of the insert and retain the first end of the insert.

2 . The mechanical branch outlet of claim 1 , further comprising a gasket having an inner diameter, the inner diameter sized to receive the first end of the insert.

3 . The mechanical branch outlet of claim 1 , further comprising a gasket defining a lower surface, the lower surface having a cylindrical contour.

4 . The mechanical branch outlet of claim 3 , wherein the cylindrical contour of the lower surface of the gasket is substantially coaxial with a longitudinal axis of the mechanical branch outlet.

5 . The mechanical branch outlet of claim 4 , wherein a rim of the insert also has a cylindrical contour.

6 . The mechanical branch outlet of claim 5 , wherein the cylindrical contour of the rim is substantially coaxial with the longitudinal axis of the mechanical branch outlet.

7 . The mechanical branch outlet of claim 1 , wherein the housing is an upper housing and includes ductile iron.

8 . The mechanical branch outlet of claim 1 , wherein the insert further includes a rim sized to retain a first end of the insert inside the housing, the rim being integral with the material of the insert.

9 . The mechanical branch outlet of claim 8 , wherein an outer diameter of the rim is greater than an outer diameter of the second end of the insert.

10 . The mechanical branch outlet of claim 8 , wherein:
a gasket of the mechanical branch outlet includes a first sealing leg and a second sealing leg and defines a recess between the second sealing leg and an upper surface of the gasket, the upper surface of the gasket in contact with the housing, the first sealing leg positioned to contact a pipe when the housing is installed on the pipe, the second sealing leg contacting the insert; and the rim is positioned inside the recess and between the second sealing leg of the gasket and an inner surface of the housing.

11 . A pipe system comprising:
a mechanical branch outlet comprising:
a housing; and
an insert including a rim for retaining a first end of the insert inside the housing; and
a pipe, the pipe defining a transverse bore in an outer wall of the pipe sized to receive the first end of the insert, the mechanical branch outlet being assembled to the pipe.

12 . The pipe system of claim 11 , wherein the insert extends from the pipe at an angle to a longitudinal axis of the pipe that is substantially equal to 90 degrees.

13 . The pipe system of claim 11 , wherein a curvature of the gasket and a curvature of an outer diameter of the pipe share a common axis when the gasket is in a non-assembled state.

14 . The pipe system of claim 11 , wherein the housing is isolated from a fluid path defined through the pipe and through the insert when the pipe system is in an assembled state.

15 . The pipe system of claim 11 , wherein a gasket of the mechanical branch outlet includes a first sealing leg in contact with an outer surface of the pipe and a second sealing leg in contact with an outer surface of the insert of the mechanical branch outlet, the gasket defining a recess between the second sealing leg and an upper surface of the gasket, the upper surface of the gasket in contact with the housing.

16 . The pipe system of claim 11 , wherein the first end of the insert extends through a transverse bore defined in an outer wall of a pipe.

17 . The pipe system of claim 11 , wherein the insert extends through the outlet bore of the housing, the pipe system further comprising a piping system element having a crimped joint crimped to an exposed portion of the insert.

18 . A method for assembling a mechanical branch outlet to a pipe comprising:
positioning a first end of an insert of the mechanical branch outlet into a transverse opening in the pipe; and assembling a housing of the mechanical branch outlet to the pipe, the housing being isolated from a fluid path defined through the pipe and through the insert when the pipe system is in an assembled state.

19 . The method of claim 18 , wherein the pipe is a first pipe, the method further comprising connecting a piping system element to the insert, the piping system element being a crimp fitting.

20 . The method of claim 18 , further comprising:
assembling a gasket to the pipe between the housing and the pipe by contacting a first sealing leg of the gasket with an outer surface of the pipe; contacting a second sealing leg of the gasket with an outer surface of the insert of the mechanical branch outlet; and inserting a rim of the insert into a recess of the gasket, the recess defined between the second sealing leg and an upper surface of the gasket, an outer diameter of the rim being greater than an outer diameter of a second end of the insert, the second end of the insert distal from the first end of the insert; and contacting the housing with each of the upper surface of the gasket and the rim of the insert.
