Title: Improvements in or relating to Apparatus for Grinding and/or Polishing Plate Glass.
IPC: B25B11/00
Filed: 1917-10-10
Abstract: 120,697. Pilkington Bros., and Slocombe, F. E. Oct. 10, 1917. Vacuum work-holders; protecting parts of machines.-A vacuum device for holding plate glass on to a table during grinding or polishing comprises a sucker adapted to adhere to the glass attached to a piston or cup of smaller area than the sucker and working in or on a cylinder carried by the table, the spaces within the sucker and the cylinder being connected together and to an exhausting means, with the result that the unbalanced atmospheric pressure on the glass is divided in a definite proportion, part operating to press the glass on to the tab, the remainder pressing the glass on to the sucker rim. Means are provided for preventing access of abrasive material to the sliding surfaces of the piston or cup. As shown in Fig. 1, the rubber ring 3 of the sucker is carried by a disk 6 secured by a perforated bolt 8 to a piston 7 sliding in a cylinder 4 secured to the table 2. The piston is pressed upwards by a spring 9 and the cylinder communicates by a pipe 5 with an air-exhausting pump. When air is exhausted from the cylinder and sucker, the pressure between the glass plate 1 and the sucker rim is proportional to the area between the dotted lines 17. As the plate 1 and the sucker and piston move inwards, the glass engages the table and the total pressure is divided between the table and the sucker rim in the proportion of the area between the lines 18 to the annular area between the lines 17, 18. Abrasive material is prevented from reaching the piston 7 by the overlap of the disk 6 and the cone or cylinder surface 11 by which the material is guided to apertures 10. In the modification shown in Fig. 3, the sucker piston is replaced by a cap 13 sliding externally on a boss 14 secured to the table 2. The cap is perforated and the vacuum space beneath it is onclosed by a rubber or like ring 15. A series of suckers may be arranged on the surface of the table, which may be horizontal, vertical, or in. verted, and the suckers may be utilized to flatten slightly buckled plates.
