Claims22
A locking joint device, comprising:
- a center body connector having an interior surface forming a cavity extending axially therethrough, wherein the center body connector includes a center flange extending a first distance radially inwardly from the center body connector interior surface;
- at least one retaining cap having an inner surface forming a retaining cap opening extending axially therethrough, wherein the at least one retaining cap has a body with an axially inner portion having a notch and a ledge formed therein, and wherein the ledge is adapted to slidingly engage the interior surface of the center body connector;
- and
- a first packing arrangement secured between the axially inner portion of the at least one retaining cap and the body connector interior surface, wherein the first packing arrangement includes a shoe gland having an outer sloped edge in sliding engagement with the at least one retaining cap axially inner portion, wherein the shoe gland further includes an intermediate surface in sliding engagement with the center body connector interior surface, and wherein the first packing arrangement further includes at least one sealing member abutting the center body connector interior surface and extending a second distance radially inwardly from the center body connector interior surface, wherein the first and second distances are the same.

A locking joint device, comprising:
- a center body connector having an interior surface forming a cavity extending axially therethrough, with the center body connector further including a first axial end wall segment;
- a first retaining cap having an inner surface forming a retaining cap opening extending axially therethrough, wherein the first retaining cap has a body with an axially inner portion having a notch and a ledge formed therein, and wherein the ledge is adapted to slidingly engage the interior surface of the center body connector;
- and
- a first packing arrangement secured between the axially inner portion of the first retaining cap and the body connector interior surface, wherein the first packing arrangement includes a flexible indicator ring secured between the axially inner portion of the retaining cap and the first axial end wall segment of the center body connector, wherein the flexible indicator ring is adapted to protrude radially outwardly beyond and adjacent the first axial end wall segment of the center body connector.
1 more element
A locking joint device, comprising:
- a center body connector comprising an outer surface and an interior surface, with the interior surface forming a cavity extending axially therethrough, and with the outer surface comprising at least one block having a substantially U-shaped slot integrally formed with and extending radially outwardly of the center body connector outer surface;
- at least one retaining cap comprising a body with an inner surface forming a retaining cap opening extending axially therethrough, wherein the at least one retaining cap further comprises an axially inner portion having a notch and a ledge formed therein, wherein the ledge is adapted to slidingly engage the interior surface of the center body connector;
- and
- a first packing arrangement secured between the axially inner portion of the at least one retaining cap and the body connector interior surface, wherein the first packing arrangement comprises a shoe gland having an outer sloped edge in sliding engagement with the at least one retaining cap axially inner portion, wherein the shoe gland further includes an intermediate surface in sliding engagement with the center body connector interior surface.
