Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
An engine mounting apparatus adapted to absorb engine vibrations in every direction comprising a base frame of a vehicle, a bracket for mounting the engine on said base frame, a first bolt means extending through a first aperture in said bracket and having a washer for fastening said bracket against said base frame, a first spacer disposed coaxially about said first bolt means, a cushion rubber disposed coaxially about said first bolt means and said first spacer between said washer and said base frame for holding said bracket, a second bolt means provided in spaced relation with said first bolt means extending through a second aperture in said bracket, and a second spacer disposed coaxially about said second bolt means, a clearance being provided between said second aperture in said bracket and the outer periphery of said second spacer, said clearance being large enough to allow vibration of said bracket during the normal running condition of the engine and small enough to allow collision of said bracket against said second spacer when excessive vibration of the engine occurs.
