The back-plate 7 is engaged in a slot 5 and retained by a bentdown tongue 9. According to the Specification as open to inspection under Sect. 91 (3) (a) the slider may be coated or otherwise treated to resemble the adjacent material in appearance and colour, but this subject-matter does not appear in the Specification as accepted. |
