Abstract

157,183. Schrader's Son, Inc., A., (Assignees of Schweinert, M. C., and Kraft, H. P.). Aug. 27, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Making, processes for ; materials, special.-A. tyre valve has a packing gasket or valve facing of rubber of sufficiently firm inelastic consistency to prevent its removal without destroying its integrity, while at the same time possessing sufficient softness to give a tight joint with its seating. The washers or gaskets are first moulded from soft rubber without vulcanizing or vulcanized for a short time only. They are then placed in the recesses formed in the metal parts to receive them and subjected to a further vulcanization preferably while enclosed in moulds.
