Abstract
Abstract A connector for coupling a compressed air source with an internally cooled mold half for use on a multiple gob individual section glassmaking machine. The connector permits the compressed air source to be automatically and quickly connected to a mold half as the mold is hung in place on the hanger arm of an IS machine. It also permits the compressed air source to be automatically and quickly disconnected from a mold half as the mold is lifted off the hanger arm. The connector is automatic or self-acting in the sense that the connection is made or broken simply by lifting the mold half onto or off the hanger arm; no manual attention to the connection is required.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
34 words
The connector of claim 1 wherein said seat is generally conical and said surface of said head has a corresponding shape such that said seat cams said head axially when moved transversely relative thereto.
Claim 2
Dependent Claim
14 words
The connector of claim 2 wherein said seat is an oblique inwardly tapering cone.
Claim 3
Dependent Claim
65 words
The connector of claim 1 further wherein said stem has at least two opposed elongated slots formed in it, said slots providing continuous air communication from said manifold into the axial passage in said head over the range of stem movement and a pin located within said manifold and extending through said elongated holes, said pin limiting the extension of said stem by said spring.
Claim 4
Dependent Claim
48 words
The connector of claim 1 wherein said seat is vertically between an upper point of attachment and a lower point of attachment of said mold to said hanger arm, such that said mold is positively prevented from movement away from said arm under the bias of said spring.
