Abstract

During the assembly of electrical equipment, it is often necessary to drive two nuts on a stud for the purpose of locking wire connections, etc. This tool drives both nuts simultaneously without jamming the second nut on the first. Thus, substantial time normally used to drive on a second nut is saved.

Magnetic Nut Driver

During the assembly of electrical equipment, it is often necessary to drive two nuts on a stud for the purpose of locking wire connections, etc. This tool drives both nuts simultaneously without jamming the second nut on the first. Thus, substantial time normally used to drive on a second nut is saved.

The tool can be either an attachment to a power head or a part of a hand tool. The tool has rear body 1 with threaded recess 3 for attachment to a rotary power source. Front body portion 2 is screwed to body 1. Within a hole in body 2 is magnet 4 urged to the left by spring 5 and moveable to the right within body
2. The left end of the central hole in body 2 is a hexagonal opening 6 to contain a nut, not shown, which is held in it by magnet 4.

Screwed to the left end of body 2 is nose piece 7 having a hexagonal opening 8 in its left end. The corners of opening 8 are offset with respect to those of opening 6. Between hex 6 and hex 8, nose piece 7 is opened up to a diameter and to a depth greater than those of a nut so that a nut is freely rotatable in opening 9. In use, a first nut is loaded into opening 9. A second nut is pushed into hex 8 and this is started on a stud. Rotation of the tool threads the nut leftward on the stud until the stud projects through the left nut and contacts the inner nut. The latter then rotates within nose 7 until the pressure from the stud and its rotation pushes the nut into hex 6. This part then drives the nut unti...
