' LEAD HEADED NAIL Filed June 17, 1955 2 Sheets-Sheet 2 [mm 22273.- EHYMOND E. CQMP and JOHN J. 6TEY6/K.

Patented Mar. 23, 1937 UNITED STATES PATENT OFFICE Jersey 111., assignors to'lhe American Steel and Wire Company of New Jersey, a corporation of New Application June 17, 1935, Serial No. 27,071 Claims. (on. 85-28) This invention relates to lead-headed nails which broadly consist of steel wire nails providing integral heads to which lead is applied so as to enclose the same.

5 One of the objects is to improve such nails so i as to eliminate slipping or loosening of the lead respecting their steel heads. Other objects may be inferred.

Referring to the accompanying drawings:

Figure 1 shows the side of a nail which illustrates the present invention and as it appears before its head is enclosed with lead.

Figure 2 shows the top of thisnail.

V Figure 3 shows the nail after its head is en-.

closed with lead, the head and lead partbeing sectioned.

Figure 4 shows the same as Figure 3 except that it is not sectioned.

Figure 5 shows the side of the head of another hall which also illustrates the invention.

Figure 6 shows the top of the last named nail.

Figure 7 shows the side of amodifled form of the nail shown by Figures 1 through 3.

Figure 8 shows the top of this modified nail.

Figure 9 shows the side of the head of still another nail which illustrates the invention.

Figure 10 is a bottom view of this nail.

More particularly, the nails are steel wire nails and each includes a shank l havinga sharpened driving point 2, and a head 3 providing a plurality of spaced protuberances l on its top surface. Specifically, there are four protuberances which are arranged close to the circumference of the head and are equidistantly spaced from each other. They are of substantial height and provide flat inclined anchoring surf aces for the lead.

' Hence they may be either rectangular of base as in the case of the protuberances 4 shown by Figures 1, 2 and 3, or may have triangular bases as in 40 the case of the protuberances 4 shown by Figures 5 and 6. In all cases they are of sufllcient height to function as anchors for preventing slippage or looseningof the lead which eventually encloses their heads. Preferably, they should be about as high as the heads are thick.

In their flnal form the nails further include the lead 5 which encloses their heads. This is shown by Figures 3 and 4 in the case of the first men tioned nail but either nail will obviously appear externally as is shown by Figure 4. The'lead may have any outside configuration providing such does not interfere with its intended function and encloses fhe nail heads.

. The modified nail shown by Figures 7 and 8 is much the same as that shown by Figures 1 through 3. It also is a steel wire nail which includes a shank 6 having a head I that provides a'plu-, rality of spaced protuberances 8 on its top sur- 5 face. It differs in that these protuberances extend upwardly from .projections 9 formed in the periphery of the head. This particular nail may prove superior respecting its ability to prevent slipping or loosening of the lead which eventually l0 encloses its head. It is to be understood that this nail likewise has its head enclosed by lead as is illustrated by the dotted lines in Figure 7. The nail shown by Figures 9 and 10 includes a shank I0 and a head ll having protuberances I 2 15 being enclosed by a relatively plastic substance. 25

2. A nail including a shank having a head providing a plurality of spaced protuberances on its top surface, said head and said protuberances being enclosed by a relatively plastic substance, and said protuberances being shaped to provide fiat inso clined anchoring surfaces for said plastic substance.

3. A nail including a shank having a head providing a plurality of spaced protuberances on its top surface, said head and said protuberances be- 35 ing enclosed by a relatively plastic substance, and said protuberances being shaped to provide inwardly facing anchoring surfaces for said plas tic substances.

4. A nail including a shank having a head pro- 7 viding peripheral projections and protuberances extending at angles from said head and said projections, said head, said projections and said protuberances being enclosed by a plastic substance.

5. A nail including a shankhaving a head pro-= viding peripheral projections and protuberances extending at angles from the tops of said head and said projections, said head, said projections and said protuberances being enclosed by a plastic 5 substance.
