Abstract

228,706. Tacchi, P. G. Nov. 16, 1923. Lever linkages; levers.- Engines driving through a rocking lever j have the fulcrum adjustable to vary the piston stroke. The lever is maintained in its position with respect to the connecting and coupling rods h, k, during adjustment of the fulcrum by various retaining devices. As shown on the right of Fig. 1 and in Fig. 4, the lever is slidable in a rocking carrier l which forms a trunnion on each side of the lever and rocks in a sleeve m fixed in slides n. The slides one on each side of the lever are movable in inclined guides o fixed on the engine frame; the movement is effected by two screws t worked together by hand or automatically by the engine governor. Keyed on each of the screws is a clutch-piece w of spherical contour and having four projections x entering grooves in the spherical interior of a worm y; the projections and grooves form a universal joint. The worms engage racks v one on each side of the lever. As the screws are turned to adjust the slides n along the guides the worm riding in the rack teeth supports the lever and prevents its lateral displacement. The inclination of the guides o may be different to that shown. As shown on the left side of Fig. 1, the lever j is fulcrumed in an adjustable arm 3 pivoted on the crank shaft; the arm receives trunnions 11 on a carrier 2 slidable on the lever. The lever is locked to the carrier in any of its adjusted positions by one or two eccentric cramps released by the handle 20 and held on by a spring 14. To prevent lateral displacement of the lever two chains 4, 7 or cables are used attached to fixed brackets 5, 8 and to opposite points 6, 9 on the lever, the chains passing through jaws in the central rod 11. In another modification the end of the lever connected to the coupling rod k is pivoted to radius links which support the lever; this is fulcrummed in blocks slidable in fixed guides, the lever riding on bearing surfaces n<2>, Fig. 9, so that it can slide slightly on its fulcrum.
