Abstract

1,245,494. Supporting inserts. KEYSTONE VALVE CORP. 8 Jan., 1969 [15 Jan., 1968; 4 Nov., 1968], No. 1142/69. Heading B5A. [Also in Division F2] A valve seat 30 formed by an annular elastomeric ring, e.g. of rubber, with a rigid tubular insert 35, e.g. of steel, is moulded in a mould 58, the insert being held in the mould by removable pins 55 and 56, which form spindle holes, and at least one removable pin 62, or 63, which extends only to the insert 35. The hole left by the pin 62, or 63 can be filled by a plug (68), Fig. 3B, not shown, which can be moulded into position or secured by adhesive.
