Abstract

12,563. Gunner, C. E. May 27. No Patent granted (Sealing fee not paid). Wood-screws.-A screw used for fastening covers, box-lids, or other removable parts to wood is made with a plain part A, Fig. 1, and a part B having a metal thread. The removable part E carries a metal plate D tapped to fit the thread B, which prevents the screw from falling out when the parts are separated. The plate D mav take the form of a socket G, Fig. 2, with spiked corners J if desired. The invention is also applicable to insulated screws for fixing slabs of slate or the like in electrical work. Fig. 4 shows an insulator X in two parts with a screw constructed as stated; both parts are threaded, and the screw may be inserted from either side.
