"My invention relates to a device, which I call an "adjustable coupling for tank-hoops." It consists of a clamp formed of screw-eye bolts bent and connected in a peculiar way, so that the ends of the hoop may be attached to this screw-clamp, and whenever the hoop becomes loose, by reason of shrinkage of the tank, or for other reasons, it may be tightened by screwing up this clamp."
