Abstract
A tamper has a housing, a transmission in the housing converting rotary movement to reciprocating movement, and a tamper plate underneath the transmission and connected thereto for tamping material over which the tamper is moved. A gasoline-fueled engine mounted on the housing supplies rotary movement to the transmission and a fuel tank mounted on the housing adjacent the engine is connected with the engine for supplying fuel thereto. A dome-shaped and downwardly concave cover fixed to the handle is positioned above the engine. The cover is made of a sound-absorbing material and includes a rigid shell having an underside provided with a layer of sound-absorbing material.
