[Also in Divisions E2 and F2] A member for aligning and retaining a gasket to an automobile engine component, such as a valve cover or sump to facilitate assembly, comprises a prong 19 made of compressible resilent material such as rubber. The prong has a wedge-shaped portion 20, a portion 23 of increased width, two wings 24 and a tapered section 21. In use, Fig. 5, the gasket 15 is positioned on the component and a prong is inserted through each hole 16 in the gasket and through the corresponding hole in the component. The end 20 of the prong is first inserted in the hole and it is pushed in until the wings 24 engage the surface of the gasket. The component and the gasket are then assembled to the mating component and the tapered sections 21 locate the parts correctly. The prongs can then be removed one at a time and replaced by the clamping bolts. The prongs are removed by pulling on the ends 20 so that the wings 24 fold against a recessed portion 27 of the tapered section 21 as they are pulled through the hole. The prong shown in Fig. 4 is designed for use in a hole of a particular diameter, a modified prong for use with holes within a range of diameters has an enlarged centre section (32), Fig. 7 (not shown), and a central slot (34) which allows the section (32) to collapse as the prong is pushed into a hole having a small diameter. The prongs may be formed integrally with the gasket, Figs. 8 and 13 (not shown). Each prong (35) having a tapered free end (39) and a wedge-shaped portion (40) by which it is attached to the gasket. Two parallel slits (41) and a transverse slit (44) define a central tongue (43) which is attached to the prong only at its outer end. A slot (45) formed across the base of the prong accommodates a lip on the component and provides a line of weakening between the prong and the component along which the prong may be torn from the gasket after use. In use the gasket is laid on the component 13, Fig. 9, the prongs are bent round and the end 40 is pushed through the aligned holes in the component and gasket. The projecting part of the prong is then used to align the assembly with the mating component. The prongs are then withdrawn one by one by pulling on the tongues 43 and the permanent fastenings are inserted. |
