Abstract
An end-cap lockingly securable to the end of the pipe at the same time a secondary action such as a branch line is formed to the main pipe line. The end cap housing has an integral branch forming member to allow a user to lock the end cap to the pipe by forming a branch line on the side of the pipe with the end cap housing sandwiching the end of a pipe between a pipe insert and a pipe receptor in the end cap housing. The pipe receptor includes an insert having a sealing surface, which when engaged to the interior surface of a pipe, forms a leak-proof relationship with the pipe.
Claims22
An end-cap incidentally lockable to a pipe comprising:
- a. a housing for engagement with a pipe, said housing having a first member;
- b. said housing having a pipe receptor, said pipe receptor having an open end and a closed end for forming a leak-proof seal on an open circumferential end of said pipe when the pipe is inserted therein;
- and
- c. a further member for incidentally securing the pipe in locked relationship to the closed end of the pipe receptor as the further member is moved through the first member into engagement with the pipe.
An end-cap lockingly securable to a pipe comprising:
- a. a housing, said housing having a pipe receptor and a tap receptor, said pipe receptor having a closed end and an open end for receiving an end of a pipe, said tap receptor having a passageway located within said tap receptor;
- b. a tap member;
- c. a hollow insert, said insert located within the pipe receptor and cantileverly attached to the closed end of the pipe receptor, said insert located radially to the tap receptor, said insert having a tapered end located distal to the closed end of the pipe receptor, said insert having an orifice located proximal to the passageway of said tap receptor for receiving a portion of a tap member to lockingly retain the pipe within the pipe receptor against the closed end of the pipe receptor;
- and
- d. a sealing surface, said sealing surface located on an exterior surface of said insert, said sealing surface creating a leak-proof seal with an interior surface of a pipe, said end-cap secured in a leak-proof condition by the engagement of the tap member to said insert to provide for communicating flow through the pipe into the insert and through the tap member.
A method of simultaneously forming a branch attachment and securing an end-cap to a pipe comprising the steps of:
- a. extending an insert into the end of a pipe to form a leak-proof seal between an interior surface of the pipe and an exterior surface of the insert;
- and
- b. extending a branch forming tap member through an orifice in a sidewall of the pipe and into engagement with the insert to thereby simultaneously form a branch attachment and lock the insert to the pipe to provide for communicating flow through the pipe into the insert and through the tap member.
An end-cap securable to a pipe as another operation is performed to the pipe comprising:
- a. a tap receptor, said tap receptor having a tap receiving end for receiving a tap, said tap receptor having a passageway located within said tap receptor;
- b. a pipe receptor, said pipe receptor having a closed end and an open end for receiving an end of a pipe;
- c. an insert, said insert having a first end and a second end, said insert connected to the closed end of the pipe receptor by the first end of said insert;
- and
- d. a sealing surface, said sealing surface located on an exterior surface of said insert, said sealing surface creating a leak-proof seal with an interior pipe surface, said end-cap securable in a leak-proof condition by the engagement of a tap member with said pipe and said insert.
