Abstract: 402,366. Glass manufacture. McNISH, A. F., 1, Priory Place, Craigie, Perth. July 13, 1933, No. 19805. [Class 56.] A method of circulating molten glass through a trough from which charges are gathered by suction-gathering, or are delivered by a feeder, consists in propelling the glass along the trough by contact between one side of the stream of glass and a moving vertical wall. The moving wall preferably consists of a cylindrical propeller 14 which is rotated about a vertical axis and is situated in a recess 13 in a wall 12 that separates two channels 6, 7 of the trough. The propeller protrudes from the recess on one or both sides of the wall 12, and the contact between it and the glass causes the glass to flow from the furnace 4 along the channels 6, 7 and return to the furnace. The trough is covered by plates 16 provided with an aperture 18 above the gathering-point 9 to permit the introduction of moulds or other gathering devices. The propeller 14 may be cylindrical or conical, and its surface may be smooth, fluted, or corrugated as desired. It may also consist of a cylinder or block having radially-extending vanes adapted to enter the stream of glass. Instead of being placed in the wall 12, the propeller may be mounted in a recess in the outer wall of the channels 6, 7. In another construction, a number of closely adjacent vertical rollers may be used, part of the surface of each being in contact with the glass. Or an endless belt or wall of refractory material may pass over vertical evolving drums, one side of the belt being in contact with the stream of glass.
