Abstract

1339845 Breathing bags MINE SAFETY APPLIANCES CO 19 April 1971 [19 Feb 1970] 20331/71 Heading AST A pair of breathing bags are formed from a blank 1, cut from a sheet of flexible impervious material, by folding the blank along the axis 4 and sealing the edges and area between the recess 2 and folded edge with a suitable adhesive 8. Before the blank is folded tubular fittings 11 are fitted into holes 3 and a relief valve 12 is fitted into the hole 5. The completed bags are swung towards each other as indicated by the arrows of Fig. 2 and the tubular fittings 11 fitted to an air treatment canister (14) to which in turn is fitted a breathing hose (17). In use the bags are hung around the neck of the user with the portion 10 against the user's neck.
