Abstract

A magnet assembly is provided including a housing having a first end and a second end. A magnet is placed within a recess formed in the first end of the housing and a spring is positioned in at least a portion of the second end of the housing. A method of mounting a magnet assembly in a tool is provided. The method includes providing a magnet assembly including a housing having a recess formed in a first end of the housing and a spring positioned in a second end of the housing. The method further includes placing the magnet assembly into an opening defined in a tool and placing a magnet into the recess, and pressing the magnet against the spring to position the magnet within the tool.

Claims (21)

1. A method of mounting a magnet assembly in a leveling tool having a measuring surface comprising:

a housing having a first end and a second end, and a magnet on the first end;

placing said housing into an opening defined in measuring surface, said opening sized to receive said housing and a spring abutting the housing and received by said second end such that said housing is biased by said spring away from the housing;

pressing said magnet against said spring to move said magnet toward the housing where said magnet is in an aligned position relative to said measuring surface; and

permanently securing said magnet in said aligned position.

2. A leveling tool comprising:

a measuring surface;

an opening defined in said measuring surface;

a magnet assembly located at least partially within said opening, said magnet assembly comprising:

a housing having a first end and a second end;

a magnet secured to said first end; and

a spring compressed between the second end and the tool; and

means for permanently fixing said housing relative to said tool such that said spring cannot move said housing relative to said tool.

3. The leveling tool of claim 2 , wherein the magnet is secured in an opening in said first end.

4. The leveling tool of claim 2 , wherein a portion of the spring is received in second recess formed in the second end.

5. The leveling tool of claim 2 , wherein the means for permanently fixing comprises adhesive.

6. The leveling tool of claim 2 , where the means for permanently fixing comprises welding.

7. The leveling tool of claim 2 , wherein the means for permanently fixing comprises a high strength spring.

8. The leveling tool of claim 2 , wherein the means for permanently fixing comprises frictional engagement.

9. The leveling tool of claim 2 , wherein the housing is formed of plastic.

10. The leveling tool of claim 2 , wherein the first end includes a plurality of recesses that allow the opening to expand when a magnet is inserted into the opening.
