Abstract: A cover for suppressing sound from a machine includes a pair of cover members having sound suppressing material thereon and connected to and supported by a pair of oppositely-disposed brackets mounted on the base of the machine. The cover members may be positioned in a horizontal plane in a closed position at least partially over the machine, and at least one of the cover members is pivotally connected to the brackets to move to an upstanding disposition in an open position. Stop members limit the movement of the pivotally mounted cover member between its open position and its closed position.
