Beveled insert for facilitating coupling pipes
An annular beveled insert for enhancing the insertion of a plain end of a pipe into a mating belled end of a pipe, the insert including an annular main body portion having a substantially flat surface and a beveled opposed surface. The annular main body portion has inner and outer diameters approximately equal to inner and outer diameters, respectively, of the plain end of the pipe. An outwardly directed flange extends from the annular main body portion around a periphery and has an outer diameter greater than the outer diameter of the plain end of the pipe. The flange is sufficiently flexible so that it bends into an angle of approximately ninety degrees with the flat surface of the annular main body portion and aids the main body portion in masking the plain end of the pipe as it passes through the annular gasket.
1. An annular beveled insert for enhancing the insertion of a plain end of a pipe into a mating belied end of a pipe, the insert comprising:
a first pipe segment having a belled end with an inner diameter, an open end, and first and second grooves formed therein, said first groove is proximal said open end and said second groove is distal said open end;
an annular gasket carried within said first groove of the belled end;
a second pipe segment having an end with inner and outer diameters;
an annular beveled insert including an annular main body portion having a substantially flat surface and a beveled opposed surface, the annular main body portion having inner and outer diameters approximately equal to the inner and outer diameters, respectively, of the end of the second pipe segment, and an outwardly directed flange extending from the annular main body portion around a periphery thereof, the flange having an outer diameter greater than the outer diameter of the end of the second pipe segment;
wherein inserting said annular beveled insert into the belled end of the first pipe segment juxtaposition the annular gasket includes temporarily inserting a portion of the outwardly directed flange of the beveled insert into said first groove in the inner diameter of the belled end of the first pipe segment;
wherein the end of the second pipe segment is placed in the belled end of the first pipe segment so as to butt the end of the first pipe segment against the flat surface of the annular main body portion;
wherein moving the end of the second pipe segment axially in the belled end of the first pipe segment with the beveled insert engaging and masking the end of the second pipe segment as the end of the second pipe segment passes through the annular gasket and moves into a seated position.
2. An annular beveled insert as claimed in claim 1 , wherein said flange of the annular beveled insert is flexible so that the flange is bendable into an angle of approximately ninety degrees with the flat surface of the annular main body portion.
