Vibration-isolating mounting for engines

Claim 1

A vibration-isolating mounting assembly for a marine engine and drive gear, said assembly comprising in combination: an engine operatively connected in a drive arrangement to transmit and receive torque forces about its axis and thrust forces along said axis; a pair of support rails extending parallel to the axis of said engine, one on each side thereof secured directly to said engine, said rails having forward and rearward ends corresponding in proximity to the forward and rearward ends of said engine; a stationary support member extending beneath each of said support rails; means including resilient pads, a plurality of aligned holes, each lined with a resilient sleeve in each of said rail and support members, and a bolt extending through each of said aligned holes, securing each of said rails to said support members to support said engine; and thrust restraining means including resilient means secured between each said rail and said support member at the rearward end of said rail substantially in the plane of and substantially in alignment therewith and operative to restrain said rail against horizontal forces acting on said engine, said thrust restraining means comprising a reaction block secured to and extending upward from said support member, a pair of face plates having plane surfaces disposed on opposite sides of said reaction block and at right angles to the axis of said engine, a resilient sound absorbing pad disposed between each of said face plates and said reaction block, a flange securing one of said face plates to said rail, and means for securing said pair of face plates together and for forcing said resilient pads into contact with said reaction block.
