DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) FIGS. 1-3 and 5 show a handle 15 of a drywall hammer 18 equipped with a magnetic nail-head retaining insert assembly 20 in accordance with the invention. The magnetic nail-head retaining insert assembly 20 retains a nail 22 by the head 24 thereof. This is particularly advantageous for a drywall installer 28 to start the starter nail 22 at the top edge 32 of a drywall panel 34, presumably because the drywall installer 28's other hand (not shown) is occupied doing or holding other things.

(14) In fact, the drywall installer is also likely to be simultaneously kicking a foot lift under the bottom edge of the sheet of drywall, and stepping on the foot lift to jam the top edge of the sheet of drywall flush up against the ceiling. Hence, in driving the first series of nails, the drywall installer is pretty much immobilized, with only one free hand available, and otherwise with no feet and nor the other hand available to help with the process.

(15) FIG. 4 shows a preliminary step in equipping an un-equipped hammer handle 15 with a bore hole for receiving the magnetic nail-head retaining insert assembly 20. The user (not shown) drills a hole 36 with a inch OD (1.27 cm OD) drill 38 or so about inch deep (1.27 cm deep).

(16) FIG. 5 shows a successive step, comprising inserting a magnetic disk 40 and a tubular sleeve 42 more or less permanently into the bore hole 36 by a driving tool 44. Preferably the tubular sleeve 42 is metallic whereas the driving tool 44 can be plastic or any convenient inexpensive material.

(17) FIG. 8 shows better the production of the metallic tubular sleeve 42. The sleeve 42 is cut off tube stock 52 by a hand-rotated pipe cutter (only the cutting wheel 54 is shown). Preferably the sleeve 42 has about a inch OD (1.27 cm OD) and is about inch (1 cm) long. Soft metals, especially copper, are very readily cut into such small pieces by such hand-rotated pipe cutters. The plane of the cut is indicated by dashed line 56.

(18) As the cutting wheel 54 rolls circumferentially on the dashed line 56 of the outer surface of the tube stock 52, the cutting wheel 54 cuts (and presses into in part) a groove in the tube stock 52 along dashed line 56 (groove not shown). After a certain number of circumferential orbits around the tube stock 52, the tubular sleeve 42 shown in FIGS. 5-7 is produced. FIG. 8 shows that the outboard end 72 of the tubular sleeve 42 is sanded, or deburred and/or flared. Conversely, as better shown in FIGS. 5 and 6, the inboard end 74 of the tubular sleeve 42 is left with its burr 76 intact. The deburred and/or flared outboard end 72 prevents from catching the nail head 24. The burr 76 on the inboard end 74 helps prevent the nail head 24 from sliding between the inboard end 74 of the tubular sleeve 42 and the magnetic disk 40. Hence both ends of the tubular sleeve 42 are formed to promote a clean ejection of the nail head 24.

(19) FIG. 9 is a perspective view comparable to FIG. 3 except showing an alternate embodiment of the magnetic nail-head retaining insert assembly 80 in accordance with the invention. FIG. 10 shows better an outer sleeve 82 in accordance with the invention which is shown in FIG. 9. Preferably this outer sleeve 82 is produced of plastic. The outer sleeve 82 has a tubular sidewall 84 extending between an inboard end 86 formed with an inwardly extending flange 88 and an outboard end 92 formed with an outwardly-extending flange 94.

(20) FIG. 11 is a perspective view comparable to FIG. 5 except showingsuspended outside the bore hole 36 in the hammer handle 15 in preparation for insertion therein, from right to leftthe same magnetic disk 40 as in FIG. 5, the same tubular sleeve 42 as in FIG. 5 except now that this sleeve 42 serves an inner sleeve 42 for the overall assembly 80, and, the outer sleeve 82 shown in FIGS. 9 and 10 (wherein the driving tool 44 shown in FIG. 5 has been omitted from this view).

(21) If the hole 36 is drilled too big or, if over time, the (inner) tubular sleeve 42 works loose, the (now inner) sleeve 42 can be refitted and things tightened up with this outer sleeve 82. Similarly, if the hole 36 is drilled too deep, the double-flanged outer sleeve 82 serves as a depth gauge for the inner, sleeve 42.

(22) The invention having been disclosed in connection with the foregoing variations and examples, additional variations will now be apparent to persons skilled in the art. The invention is not intended to be limited to the variations specifically mentioned, and accordingly reference should be made to the appended claims rather than the foregoing discussion of preferred examples, to assess the scope of the invention in which exclusive rights are claimed.
