This article is not intended and shall not be executed, enforced or construed so as to allow any diversion or conversion of any particular sinking funds, or part thereof, from the object and purpose for which such particular fund or part thereof was created, but they shall be executed and enforced so as to enhance and increase the value of all sinking funds and to apply each particular fund and the increased value or interest accruing therefrom to the prompt and faithful payment of the particular indebtedness or obligation for which the fund was created, and no sinking funds or any part thereof shall be devoted to any other use or purpose than that for which it was created and provided.
