Abstract
Abstract A mechanism which aligns and connects the inlet of a receiving vessel with the outlet of a teeming vessel. When molten metal is teemed into a vacuum-degassing vessel, it is necessary to have an airtight connection between vessels to maintain the vacuum, and it is difficult to align the vessels with the necessary precision to achieve such a connection. The invention provides a cam means for automatically shifting an inlet tube on the receiving vessel into alignment with the outlet of the teeming vessel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
The combination, with a teeming vessel having an outlet opening in its bottom wall and a receiving vessel having an inlet opening in its top wall, of a connecting device comprising an inlet tube, means on said receiving vessel supporting said tube in said inlet opening for horizontal shifting movement, and cooperating cam means on said supporting means and said teeming vessel for automatically moving said tube into alignment with said outlet opening when said vessels are brought together.
Claim 2
Dependent Claim
79 words
The combination, with a teeming vessel having an outlet opening in its bottom wall and a receiving vessel having an inlet opening in its top wall, of a connecting device comprising an inlet tube, means on said receiving vessel supporting said tube in said inlet opening for horizontal shifting movement, and cooperating cam means on said supporting means and said teeming vessel for automatically moving said tube into alignment with said outlet opening when said vessels are brought together.
Claim 3
Dependent Claim
56 words
A combination as defined in claim 1 in which said cam means includes first and second sets of cam surfaces on said supporting means and said teeming vessel, said first set engaging to start said tube toward a position of alignment, said second set engaging after said first set engages to move said tube into alignment.
Claim 4
Dependent Claim
52 words
A combination as defined in claim 1 in which said supporting means includes a plurality of fluid pressure cylinders upstanding from said receiving vessel, an annular thrust bearing carried by said cylinders for vertical movement, and an annular plate carried by said bearing for horizontal movement, said tube depending from said plate.
Claim 5
Dependent Claim
33 words
A combination as defined in claim 3 in which said receiving vessel has a counterbore around said inlet opening and comprising in addition a ring mounted in said counterbore and receiving said tube.
Claim 6
Dependent Claim
49 words
A combination as defined in claim 3 in which said plate has a beveled circumferential edge forming a cam surface, and said cam means includes guides depending from said teeming vessel and having cam surfaces engageable with said beveled edge to start said tube toward a position of alignment.
Claim 7
Dependent Claim
35 words
A combination as defined in claim 3 in which said plate carries blocks having upwardly opening sockets and cam surfaces above said sockets, and said teeming vessel carries downwardly depending tongues receivable in said sockets.
Claim 8
Dependent Claim
28 words
A combination as defined in claim 3 comprising in addition an expansible bellows connecting said receiving vessel and said bearing and encircling said tube to furnish a seal.
Claim 9
Dependent Claim
131 words
A combination as defined in claim 1 in which said supporting means includes a plurality of fluid pressure cylinders upstanding from said receiving vessel, an annular thrust bearing carried by said cylinders for vertical movement, and an annular plate carried by said bearing for horizontal movement and having a beveled circumferential edge forming a cam surface, said tube depending from said plate, and in which said cam means includes guides depending from said teeming vessel and having cam surfaces engageable with said beveled edge to start said tube toward a position of alignment, blocks carried by said plate having upwardly opening sockets and cam surfaces above said sockets, and downwardly depending tongues on said teeming vessel receivable in said sockets after the cam surfaces on said guides engage said beveled edge.
Claim 10
Dependent Claim
49 words
A combination as defined in claim 8 comprising in addition a two-part sliding gate closure for said outlet opening, one part being mounted on said teeming vessel, the other part being mounted over said tube, said parts having concave and convex surfaces adapted to engage to achieve finAl alignment.
Claim 11
Dependent Claim
39 words
A combination as defined in claim 1 in which said vessels and said tube are refractory lined to handle molten metal, said receiving vessel being under vacuum, and comprising in addition means furnishing an airtight seal around said tube.
