Title: Automatic glass feed
IPC: C03B7/082
Filed: 1934-11-09
Abstract: 428,123. Glass manufacture. HILGENBERG, C. G., and GARWOOD, C. B., c /o Carr- Lowrey Glass Co., Baltimore, U.S.A. Nov. 9, 1934, No. 32369. [Class 56] Relates to a feeder of the pneumatic type in which a tubular member 5 is submerged in molten glass above an outlet 2 in the floor of a forehearth 1, the flow of glass through the outlet being formed into " gobs " by the alternating application of suction and compresson to a space 7 within the member 5. According to the invention, the member 5 rests on the floor of the foreheath, the glass flows to the opening 2 through ports 10 in the wall of the member 5, and the flow is controlled by a float 8 which rises and falls within the space 7 with the application of the suction and compression. The suction chamber 7 is of cylindrical form, and its upper end 9 provides a seat and a stop for the float valve 8. The ports 10 slope upwards to points near the surface of the glass G in order that the hotter and more fluid surface glass shall be used. When the float 8 moves upwards from the position shown, it draws back into the space 7 the stub end of glass left in the outlet 2, and remelts and obliterates the shear mark. As the float continues to move upwards, it uncovers the ports 10 and hot glass flows into the space 7. On the downward movement of the float, the glass in the space 7 is forced through the outlet 7 and is cut off by shears in the usual way. The application of suction and pressure to the space 7 is controlled by a number of valves 29 which open and close the passage between a pipe 15, connected to the space 7, and pipes 22 which are connected to sources of suction and compression, and to the atmosphere. Each valve 29 is reciprocated in its casing 21 by a crank 36 which is rotated by a driving shaft 53, and the position of the valve in its casing can be adjusted by means of a handwheel 32 to regulate the amount of suction or compression applied to the space 7. A sleeve 58, which can be moved along the shaft 53 by means of a handwheel 69, allows the operation of the valve to be advanced or retarded. The valves 29 are arranged to open the space 7 to the atmosphere between the applications of suction and compression.
