The spindle is cut with screw-threads. The roseis made in two portions, one being screwed to the door, andthe other acting as a binding-screw or washer, screwing ontothe threads of the spindle at the same time that the shank ofthe knob screws behind it, the two locking, and preventing theknob from being unturned except by forcible means. As thespindle is held in the latch, the knob can, of course, be turned. Fig. 368 Knob with threaded Co. Stoddard Lock
