Conduit connectors

Claim 2

In combination with a nipple secured to the end portion of a conduit and a flange extending radially outward from a free end of a second conduit, the improvement of a manifold connector assembly for coacting said nipple and said flange into axial bias into said connector, said connector comprising: a substantially cylindrical housing having an inner bore; a connector ring neck integrally attached and disposed on one end of said housing; a rotatable connector ring secured axially around said ring neck, said connector ring having an inner surface; a plurality of connector teeth disposed radially inward around the inner surface of the connector ring; a flange-receiving a plurality of connector teeth on the nipple for engaging face disposed in the end of the housing opposite the end on which said connector ring is disposed; an annular groove disposed in said flange-receiving face of the connector housing adjacent to the inner bore; sealing means freely disposed in the annular groove; and connector means disposed on the outer peripheral circumference of the connector housing at the end opposite the connector ring neck for securing said manifold connector to said flange said nipple and said flange being connected to said cylindrical housing whereby the free end of the nipple and the end face of the flange are sealingly biased by said sealing means.

Claim 3

The combination according to claim 1 in which the connector means comprises a plurality of arcuate connector lugs.

Claim 4

The combination according to claim 2 in which the connector lugs have gripping edges, two of said lugs being diametrically opposite and having locking support pads disposed on the gripping edges.

Claim 5

The combination according to claim 1 in which the connecting means comprises a substantially hemispherical, arcuate lug.

Claim 6

The combination according to claim 1 in which the sealing means has axial end surfaces having deformable sealing rings disposed such that the deformable sealing ring in one end is biased against the free end of the nipple and the deformable ring on the other end is biased against the flange.

Claim 7

The combination according to claim 1 in which the connector ring has disposed from its outer periphery a plurality of impact lugs.

Claim 8

The combination according to claim 1 in which locking pins are disposed on the outer periphery of the connector ring and spaced locking fins are disposed on the outer peripheral surface of the nipple; said locking fins oriented in a position such that when the pins are biased toward the nipple, said pins are disposed in the spaces between the locking fins.

Claim 9

The combination according to claim 1 in which the nipple has a plurality of connector teeth radially disposed from its outer peripheral surface; said connector teeth having contact surfaces complimentary to contact surfaces of said connector teeth disposed around the inner surface of said connector ring such that axial sealing force is imparted relative to said manifold connector and said nipple when said connector ring is rotated and the contact surfaces of the teeth are meshed.

Claim 10

The combination according to claim 1 in which the connector teeth of said connector ring have terminal ends, stop lugs are disposed from said terminal ends in such a disposition that the stop lugs will come into contact with the leading edge of the connector teeth of the nipple.

Claim 11

In combination with a nipple secured to the end portion of a conduit and a flange extending radially outward from a free end of a second conduit, the improvement of a manifold connector assembly for coacting said nipple and said flange into bias into said connector, said connector comprising: a substantially cylindrical housing having an inner bore; an axially and integrally connector ring neck disposed on one end of said housing; a rotatable connector ring secured axially around said connector ring neck, said connector ring having an inner surface; a plurality of connector teeth disposed radially inward around the inner surface of the connector ring for engaging a plurality of connector teeth on the nipple; a plurality of notches in the inward circumference of said connector ring for receiving said nipple connector teeth within said connector ring; a flange-receiving face disposed in the end of the housing opposite the end on which said connector ring is disposed; an annular groove disposed in said flange-receiving face of the connector housing adjacent to the inner bore; sealing means freely disposed in the annular groove; and connector means disposed on the outer peripheral circumference of the connector housing at the end opposite the connector ring neck for securing said manifold connector to said flange said nipple and said flange being connected to said cylindrical housing whereby the free end of the nipple and the end face of the flange are sealingly biased by said sealing means.

Claim 12

In combination with a nipple secured to the end portion of a conduit and a flange extending radially outward from a free end of a second conduit, the improvement of a manifold connector assembly for coacting said nipple and said flange into bias into said connector, said connector comprising: a substantially cylindrical housing having an inner bore; an axially and integrally connector ring neck disposed on one end of said housing; a rotatable connector ring secured axially around said connector ring neck, said connector ring having an inner surface; a plurality of connector teeth disposed radially inward around the inner surface of the connector ring for engaging a plurality of connector teeth on the nipple; a plurality of notches in the inward circumference of said connector ring for receiving said nipple connector teeth within said connector ring; a flange-receiving face disposed in the end of the housing opposite the end on which said connector ring is disposed; an annular groove disposed in said flange-receiving face of the connector housing adjacent to the inner bore; sealing means freely disposed in the annular groove; and connector means disposed on the outer peripheral circumference of the connector housing at the end opposite the connector ring neck for securing said manifold connector to said flange said nipple and said flange being connected to said cylindrical housing whereby the free end of the nipple and the end face of the flange are sealingly biased by said sealing means.
