Four members of the Board shall constitute a quorum for the transaction of business. All action of the Board shall be by ordinance or resolution and the affirmative vote of at least 4 members shall be necessary for the adoption of any ordinance or resolution. All such ordinances and resolutions before taking effect shall be approved by the chairman of the Board, and if he approves thereof he shall sign the same, and such as he does not approve he shall return to the Board with his objections thereto in writing at the next regular meeting of the Board occurring after the passage thereof.
