Abstract

In accordance with the present invention one device for locating ferrous object(s) that are visually obscured by a non-magnetic surface material and for temporarily holding a mostly ferrous fastener in the correct position to be affixed until firmly started.

Claims

1. A device for magnetically locating ferrous object(s) that are visually obscured by a non-magnetic surface material and for temporarily magnetically holding a mostly ferrous fastener in position to be affixed, the device comprising:

at least one magnet;

the at least one magnet having the strength to attract and locate the ferrous object that is visually obscured by the non-magnetic surface material;

the magnet having the strength to attract and hold the weight of the device onto the non-magnetic mounting surface by attracting to the ferrous object disposed behind the non-magnetic mounting surface;

the magnet having the strength to hold at least one fastener to be affixed in affixing position;

the affixing position being at least ¼

″

away from the magnetic center of the magnet and directly vertically above or below the magnetic center;

the device having at least one affixing position, linear groove, perpendicular to the non-magnetic mounting surface and being located at least ¼

″

away from the magnetic center of the magnet and directly vertically above or below the magnetic center;

2. The device of claim 1 wherein the device while suspended magnetically from the visually obscured fastener, will pivot on the magnetic center, rotating the heavier end down by gravitational force and simultaneously rotating the linear groove into a vertical position above or below the magnetic center.

3. The device of claim 1 wherein said at least one magnet is disposed at least partially in a non-magnetic enclosure.

4. The device of claim 1 wherein said at least one magnet is multiple magnets disposed in a non-magnetic enclosure.

5. The device of claim 1 wherein said at least one magnet is affixed to a ferrous metal plate, said plate being no larger than 3 times wider, 3 times longer and 1 time as thick as said magnet, said device being mostly attracting towards the ferrous object to be located and mostly non-magnetic on the side away from the ferrous object.

6. The device of claim 1 wherein said device has a through hole to attach a plumb line.

7. The device of claim 1 wherein the distance from the magnetic center pivot to the fastener starter groove is adjustable by making the at least partial enclosure longer a longer solid piece or by making the at least partial enclosure length adjustable by mechanical means.

8. The device of claim 1 wherein the device while suspended magnetically from the visually obscured fastener, will pivot on the magnetic center, rotating the heavier end down by gravitational force and simultaneously rotating the linear groove into a vertical position above or below the magnetic center, having multiple magnets, having a ferrous metal plate, being disposed at least partially in a non-magnetic enclosure, with a through hole to attach a plumb line.
