Abstract

258,967. Pilkington Bros., Ltd., and Griffin, J. H. July 7, 1925. Flat extended surfaces, surfacing.-The polishing runners of a glass polishing machine are washed without interruption of the operation of the machine by introducing a washing table between the runner and the glass whereby spent rouge &c. is removed. The glass is carried by tables 1 which travel on guides 2 beneath the polishing runners 9. The runners are carried by a shaft 7 which may be raised or lowered by a lever 12 and hand-wheel 10. On rails 19 parallel to the guides 2 is mounted a framework 17 having thereon girders 16 which may be brought into register with transverse girders 15 on the frame 4<a> of the machine. When the runners are to be washed, a washing table 20 carried by rollers 22 on the girders 15 or 16, is run between the raised runners and the table 1, the runner is let down on to the table 20 and is washed; it is then raised and the table run out on to the girders 16. In a modification, Fig. 3, the washing table 20 is carried, in a position above the tables 1, by wheels 23 on rails 24, and may be moved along the machine to any desired set of runners; when not in use, the table is located between runners or at the end of the machine. The washing table may be employed with apparatus in which the runners operate on the lower surface of the glass. The Provisional Specification also describes washing- apparatus in which the table or the carrying frame may be supported, or partially supported on the glass, and the contact between the glass and the plate &c. may be made by means of rollers.
