Abstract: 858,124. Moulding plastic pistons. WHITE, C. S. April 29, 1957 [May 9, 1956], No. 13590/57. Class 87(2). [Also in Groups XXV and XXVI] A piston is moulded from a synthetic resin in situ within a cylinder at a predetermined pressure and with an interposed layer of lowfriction material so arranged that it becomes bonded to the surface of the piston. In the arrangement shown in Fig. 1, synthetic resin to form the piston 26 in a cylinder 11 is injected under pressure through an opening 28 in an upper plug 29 in the cylinder so that the piston is moulded between this plug and a lower plug 13. A sleeve 24 is fitted inside the cylinder with its outer surface 25 formed of a fluorocarbon resin disposed against the cylinder wall and its inner surface either formed to bond with the material of the piston or actually bonded to an inner resilient sleeve 27 ; upon setting of the piston material, the sleeves. 24, 27 are forced against the cylinder wall at the desired pressure. The lower plug 13 is apertured to receive the connecting rod 15 or a piston rod, and, in the case of a connecting rod, the pin 19 is moulded in the piston with a layer 23 of synthetic resin bonded to the head 22. In the form shown in Fig. 2, the piston 31 is moulded apart from the cylinder from a phenolic resin which is cured to the B-stage, and, after application of its outer surface of a sleeve 32 of a fluorocarbon, with or without an intervening resilient sleeve is inserted into the cylinder. The piston is then pressed against the lower plug 13 while head is applied so that the resin is cured to the C-stage and the piston is moulded to the desired form in which it enbraces the head 35 of a connecting-rod 36 ; the moulding pressure ensures that the desired pressure engagement occurs between the sleeve 32 and cylinder wall. In a further form, a hollow piston 42, Fig. 3, pre-formed from metal or synthetic resin, is inserted in the cylinder and synthetic resin is then forced into a space 49 which separates it from the inner surface of either a sleeve 47 of fluorocarbon resilient material or a resilient sleeve 48 carried inside such sleeve.
