Abstract: A chassis for the transportable mounting of vibrating equipment includes a main frame for supporting the vibrating machinery, a ground engaging wheel assembly at one end of the main frame, a ground engaging support bracket member positioned at the opposed end of the main frame, and a point coupling member for connecting the bracket member to the main frame. The coupling member includes an elastomeric, generally disk-shaped damping member interposed between the main frame and the support bracket at the intersection of the support bracket with the center line of the main frame. A threaded bolt and nut assembly is received through the damping member for adjustable compression of the damping member. The support bracket is received through notches in downwardly depending side flanges of the main frame, limiting the range of relative motion between the main frame and the support bracket.

Abstract: An apparatus for reducing or eliminating the occurrence of vapor lock in two-cycle engines isolates the fuel pump from the heat radiating engine block in a two-cycle, air cooled engine spaces the fuel pump from the carburetor and injects the fuel directly against the carburetor inlet valve. Application of an additional cooling means including airflow and liquid fuel means, may be provided in order to convey heat away from the fuel pump and therefore maintain the fuel pump temperature below the point at which vaporation pressure exceeds the impulse pressure generated from the power head. The fuel pump is removed from the hot carburetor as part of the vapor lock prevention system.
