Abstract
A graphite funnel inserted into a metal funnel support sleeve guides hot glass gobs from a furnace to the glass blowing mold. The graphite insert is adjustable by set screws and is easily repositioned. The graphite insert has an outer diameter slightly less than the metal retainer to allow ambient air to pass upwardly past it.
Claims14
A graphite glass gob funnel assembly comprising:
- an outer cylindrical support sleeve having an outer diameter at an upper surface;
- and
- an inner substantially tube shaped monolithic piece of graphite having a tubular body resting on the upper surface of the support sleeve, wherein said tubular body is rotatively repositionable on said sleeve between a plurality of stationary positions and assembly includes means for fixedly receiving said tubular body in each of said positions with respect to said support sleeve.
An apparatus for handling formable glass comprising:
- an internal passageway extending from an entry to a second location, wherein said passageway is capable of handling said formable glass from said entry location to said second location distal from said entry location;
- an exterior surface substantially free of cooling protrusions;
- and
- wherein said apparatus is substantially composed of a material capable of handling said formable glass in the absence of a cooling fluid flow driven by mechanical means and wherein said apparatus is also capable of being supported in a plurality of adjustable positions.

A funnel comprising:
- a substantially tubular body defined on the exterior by (a) a top collar portion having an outer diameter and a length, said top collar portion terminating at the bottom of its length in a ledge, and (b) a bottom substantially conical portion;
- said body substantially composed of graphite and further defining an interior surface forming a tubular passageway from the top end of the top collar portion to the bottom end of the bottom conical portion defined by an interior diameter greater at the top end than at the bottom end;
- and
- means for rotatively repositioning and fixedly securing said tubular body in a plurality of stationary positions with respect to a support for said tubular body.
1 more element
The process of molding glass which comprises:
- heating glass gobs in a furnace;
- releasing at least a portion of said heated glass gobs from said furnace to a funnel;
- discharging said heated glass gobs from said funnel to a molding machine wherein said funnel is fixedly secured against rotational movement in a position with respect to said molding machine;
- and
- rotatably repositioning said funnel to one of a plurality of positions with respect to said molding machine after said discharging step.
