The lien of any judgment entered upon any award shall not be divested by any appeal. If, however, the party appealing from the award shall file with the board a bond, in such amount and in such form as the rules and regulations of the board shall direct, the appeal shall, pending its decision, excuse the payment of so much of the compensation as is contested therein; but if the final decision on appeal shall sustain the award, it shall be the duty of the employer by whom such award is payable to make payments of compensation as from the date of the original award. If on appeal the award is sustained as to a part, it shall be the duty of the employer by whom such part is payable to make payments as from the date of the original award. In case the award is annulled on appeal, it shall be the duty of the prothonotary of any county in which such award has been entered as a judgment to mark it satisfied.
