ABSTRACT:
A door knob construction featuring a machined knob and cover to incorporate decorative detail. The knob construction consists of a knob body, a shank threadably connected to the knob body and a cover which fits over the shank to complete the decorative knob assembly. The knob body is hollow to accommodate the lock cylinder and includes a small diameter hole through which the cylinder protrudes. The back of the knob body includes threads to accept the knob shank. Upon assembly, a bore is drilled across the threads and a pin is inserted to prevent disassembly of the knob body from the shank. The shank includes longitudinal ridges to form an interference fit with the decorative shank cover.
