Abstract
Abstract The takeout mechanism for a glass container forming machine has an operating rod movable axially toward the container to engage the takeout mechanism with the container at the final mold of the forming machine. This rod comprises a treatment gas conduit and is extended to project into the container when the takeout mechanism is in gripping engagement with the container. Valve means are provided for supplying a measured quantity of treatment gas under pressure to the conduit while the same is projected into the container during a takeout operation. The measured quantity is supplied to the conduit by making equal the pressure in an accumulator of gas and a pressure source by way of the valve means, and then allowing the gas to pass from the accumulator to the conduit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
Apparatus for applying gaseous surface treatment to the interiors of newly formed glass containers comprising a takeout mechanism and conduit means associated therewith for insertion into the open ends of containers to inject treatment gas thereinto, a source of said treatment gas under predetermined controlled pressure, an accumulator connected with said source for receiving gas under pressure from said source, a connection from said accumulator to said takeout mechanism conduit means, and valve means for alternately connecting said accumulator with said pressure source to equalize the pressure between the source and the accumulator, and then with said conduit means to successively receive a charge of treatment gas under pressure from said source and then discharge the same to said takeout mechanism conduit means.
Claim 2
Dependent Claim
123 words
Apparatus for applying gaseous surface treatment to the interiors of newly formed glass containers comprising a takeout mechanism and conduit means associated therewith for insertion into the open ends of containers to inject treatment gas thereinto, a source of said treatment gas under predetermined controlled pressure, an accumulator connected with said source for receiving gas under pressure from said source, a connection from said accumulator to said takeout mechanism conduit means, and valve means for alternately connecting said accumulator with said pressure source to equalize the pressure between the source and the accumulator, and then with said conduit means to successively receive a charge of treatment gas under pressure from said source and then discharge the same to said takeout mechanism conduit means.
Claim 3
Dependent Claim
23 words
Apparatus as in claim 1 wherein said conduit means is inserted in a container by engagement of the takeout mechanism with the container.
Claim 4
Dependent Claim
21 words
Apparatus as in claim 1 wherein said valve means is operated alternately in synchronism with the operation of said takeout mechanism.
Claim 5
Dependent Claim
21 words
Apparatus as in claim 2 wherein said valve means is operated alternately in synchronism with the operation of said takeout mechanism.
Claim 6
Dependent Claim
41 words
Apparatus as in claim 3 wherein said valve connects said accumulator with said takeout mechanism conduit means after the takeout mechanism engages a container and disconnects the accumulator from said conduit means before the container is released by the takeout mechanism.
