3. The combination of a container for moiiron glass having a discharge orifice be- ,iaziv the level of the glass, means to con Carol the discharge of glass therethrough, said means comprising amechanical mcmher Within the glass adjacent the orifice, means for periodically reciprocating said member in a direction transverse to the direciion of movement of glass through the orifice, and means cooperating with said member so substantially close the orifice while said member is at the limit of its movement in one direction.

8. iiiess feeding mcc-i'ianism eoni prisin in combination, a. receptacle for molten glass having a discharge opening in the bottom thcrcoi', means to control the discharge of glass through the opening comprising a pair of heads Within the gloss over the opening, and means to rccipr onto said heads hori zoninliy and cause them to pcriodically meet over said openint, .uid heads having their meeting faces recessed to form a reservoir in communication with the discharge opening.

9. Glass feeding mechanism comprising, in combination, mreceptncle contain molten glass provided with an outlet opening in the bottom thereof, regulating means comprising heads Within the gloss over said opening, lever arms carrying said heads, coins operative to periodically actuate said arms and thereby horizontally reciprocate, said heads in the glass in a dircciioin ironsvcrse to the flow of glass through the opening and cause them to meet over said openmg, and means to effect a relative adjustment of the cams and thereby adjust the meeting position of said heads.

' 10. In gloss feeding mechanism, the combination of a furnace, a forehcurth or extension projecting therefrom in which a continuous suppiy of molten ,glass from the furnace is maintained. said extension inciuding a cover providing a confined space over" the glass, said extension having an outlet opening in the bottom thereof adjacent its ouier end, :in island projecting upward in the boot between aid opening and the furnucc, said island having a. passageway ihcrcihrough opening: into the interior of ihe forchcarth over the glass, and; ii hurner for supplying: burning gases through said passageway inio said confined space.
