Abstract

154,661. Pilkington Bros., and Waldron, F. B. July 31, 1919. Flat extending surfaces, surfacing and polishing.-Plates of glass are mounted for grinding and polishing on rectangular tables adapted to be passed in a series, with their adjacent ends in contact, beneath sets of runners each supplied with a particular grade of abrasive, and means are provided whereby each table, as it passes the last set of runners, may be removed, and another table may be added to the series. The tables 1 are supported and guided by a bed 2 and are moved therealong by worm-driven rack-and-pinion gearing 11, 12 or by a chain, the glass plates passing under sets of runners 3 in succession; the tables may be connected together at their adjacent ends by lugs 15 and cotters, or may contact with each other without being connected. As a table emerges from the last set of runners, it passes on to a trolley 17; the glass is turned over, in order that its other surface may be ground &c. and the trolley is brought to the other end of the bed at 18 and the table is placed in contact with the first table and again passed through the machine. The runners are supported on vertical shafts, mounted in bearings carried by frames 5, 6, and driven by means of pulleys 9. Each set of runners is supplied with one grade of abrasive only and the abrasive is washed off the glass as this passes from one set of runners to the next set, the sets being spaced sufficiently far apart to allow this and also to prevent admixture of grades by centrifugal force. The Provisional Specification describes also apparatus in which the tables are moved by a conveyer, which returns from the finishing end of the apparatus to the starting-end after a table has been detached,
