by general or special rule, authorize the Commissioner of Public Works,
the Police Chief, the Fire Commissioner or the Director of the Bureau

delivered to him or it, and he shall approve, in writing, all claims
for any such materials or supplies purchased by him before the same
shall be presented to the Comptroller for audit.
