Abstract

1473355 Washers; joint making packing NATIONAL PLANT HIRE (PTY) Ltd 15 July 1974 [17 July 1973 19 July 1973 14 May 1974] 31279/74 Headings F2B and F2H A sealing washer assembly for use, e.g. with roofing nails 8, comprises a rigid washer 1 and a sealing washer 2 having a ridged formation for engaging the surface through which the nail is passed and a projection 12 passing through the washer 1. The bore 6 may have a diaphragm across it (not shown) for piercing by the nail or a ridge 4 may engage the nail to ensure sealing. Alternatively the bore may have one or more tapered portions, the narrow parts of which engage the nail. The portion 12 may be of expanded form to retain the washers assembled or may be a loose fit in the rigid washer and be compressed by the head of the nail, Fig. 7 (not shown). The washers 1, 2, may be each made up in latches joined at their edges by integral portions. The two batches can then be assembled in one operation and individual assemblies separated as required. Reference has been directed by the Comptroller to Specification 1,243,547.
