Abstract A glass making machine and particularly a heat treat machine wherein open-ended hollow glass articles are supported on carriages moved in an endless path by a conveyor. Each carriage pivotally supports a plurality of heads which, in turn, rotatably support the hollow glass articles. The conveyor moves the carriages and in turn the articles through a plurality of work zones of heat treatment including heating, quenching and cooling zones. As the articles are moved through a work zone, the supports on the heads are rotated to rotate the articles. The work zone includes burners for applying flames to the lower open end of the articles while rotating. A hold down device engages the opposite upper end of each of the articles while in said path, and holds the articles in the support carriage. Next the articles travel in a second path through cooling means.
In a glass making machine, the combination comprising conveyor means for moving a plurality of glass articles which have one end closed and the other end open in a first horizontal path, said conveyor means comprising support means for circumferentially engaging and supporting each glass article with the closed end in generally upward position in said first horizontal path, burner means adjacent said conveyor means along said first path for applying flames to the other open end of said glass articles, means adjacent said conveyor means for rotating said support means and thereby rotate said glass articles while they are moving through said first path, hold down means adjacent said conveyor means overlying said support means and engaging the closed ends of said glass articles while they are supported by said conveyor means in said first path to hold said articles on said conveyor.

In a glass making machine, the combination comprising conveyor means for moving a plurality of glass articles which have one end closed and the other end open in a first horizontal path, said conveyor means comprising support means for circumferentially engaging and supporting each glass article with the closed end in generally upward position in said first horizontal path, burner means adjacent said conveyor means along said first path for applying flames to the other open end of said glass articles, means adjacent said conveyor means for rotating said support means and thereby rotate said glass articles while they are moving through said first path, hold down means adjacent said conveyor means overlying said support means and engaging the closed ends of said glass articles while they are supported by said conveyor means in said first path to hold said articles on said conveyor.
Claim 3
Dependent Claim
57 words
The combination set forth in claim 1 wherein said conveyor means moves said glass articles through a second horizontal path, cooling means adjacent said conveyor means along said second path for applying cooling fluid downwardly onto the closed upper ends of said glass articles and upwardly into the interior and onto the exterior of said glass articles.
Claim 4
Dependent Claim
57 words
The combination set forth in claim 1 wherein said burner means are positioned such that flames are directed horizontally toward said conveyor means including means adjacent said conveyor means and said hold down means along said first path for preventing direct impingement of flames from said burner means onto said conveyor means and said hold down means.
