Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
A magnetic nail driver comprising: a. a cylindrical tube made of nonmagnetic material having a handle end and a magnetic end, b. a rod-shaped driver telescoped within the tube, c. a weighted handle on the driver, the handle extending from the handle end of the tube, d. a tubular magnetic holder over the tube at the magnetic end forming e. an annular space between the magnet holder and tube, and f. a plurality of permanent bar magnets in the magnet holder, g. all said magnets aligned with the tube and oriented in the same direction.
Claim 2
Dependent Claim
95 words
A magnetic nail driver comprising: a. a cylindrical tube made of nonmagnetic material having a handle end and a magnetic end, b. a rod-shaped driver telescoped within the tube, c. a weighted handle on the driver, the handle extending from the handle end of the tube, d. a tubular magnetic holder over the tube at the magnetic end forming e. an annular space between the magnet holder and tube, and f. a plurality of permanent bar magnets in the magnet holder, g. all said magnets aligned with the tube and oriented in the same direction.
Claim 3
Dependent Claim
17 words
The invention as defined in claim 1 wherein the magnets are held in place by epoxy resin.
Claim 4
Dependent Claim
37 words
The invention as defined in claim 1 with an additional limitation of e. the length of said driver from the weighted handle to the end which strikes the nail being greater than the length of the tube.
