Anstett, 21. Lakewood Place, Highland Park, Ill. 60035 Filed Oct. 30, 1964, Ser. No. 407,630 5 Qlaims. ((Il. 227-95) The principal object of this invention is to provide an improved nailing strip wherein headed nails may be progressively severed and driven therefrom by a nailing machine, such as the pneumatically power operated nailing machine disclosed in my copendin-g application Serial No. 211,551, filed July 23, 1962, issued as Patent No. 3,211,- 352 on October 12, 1965, but wherein the die and plunger construction of the nailing machine has been modified to cooperate with the nailing strip of this invention. A further object of this invention resides in the cooperative relationship between the nailing strip of this invention and the modified nailing machine which has been modified in accordance with this invention.
In accordance with this invention, headed nails are not sheared or punched from the nailing strip nor are the heads thereof formed as they are sequentially driven from the nailing strip by the nailing machine, but, instead, the headed nails are predefined in the nailing strip and are broken therefrom by the nailing'machine. As a result, uniformly dimensioned headed nails are formed, accurate feeding of the nailing strip in the nailing machine is facilitated, and the need for close tolerances in the die and plunger construction of the nailing machine is eliminated. By reason of this invention, therefore, nailing strips may be more accurately and inexpensively formed, predefined headed nails may be more accurately and readily severed and driven from a nailing machine, and the life of the nailing machine may be greatly extended.
Briefly, the nailing machine of this invention, may be of the type disclosed in my aforementioned copending application or of similar types, includes a backing die provided with an opening and a reciprocatable plunger in alignment with the die opening and having transverse dimensions which are substantially less than the die opening dimensions. Such a die and plunger construction difiers from those of the aforementioned types of nailing machines wherein the headed nails are sheared or punched from the nailing strip and wherein the dimensions of the die opening and the plunger must necessarily be substantially the same within close tolerances.
The nailing strip of this invention for use in the nailing machine of this invention includes an elongated molded strip having substantially parallel side edges, and a plurality of pointed nail shanks extend from one face of the strip intermediate the side edges thereof and in spaced apart relation along the strip. Recesses are molded in at least one face of the strip about each nail shank to weaken the strip thereat and define the outline of a nailhead for each nail shank. The dimensions of the defined nailheads are less than the dimension of the backing die opening and greater than the dimension of the plunger.
When the nailing strip is fed into the nailing machine, the strip is backed by the backing die outwardly from the recesses since the backing die opening is of greater dimension than that of the predefined nailheads in the strip, and the plunger engages the strip within the recesses since the plunger dimension is less than the dimension of the predefined nailheads. As a result, the strip is sequentially fractured at the strip weakening and head defining recesses molded in the strip for sequentially severing and driving predefined headed nails from the strip as the strip is sequentially advanced between the backing die and the plunger. The nailing machine is provided with an Patented Dec. 27, 1966 indexing stop for. controlling the intermittent or sequential advance of the nailing strip.
Since the headed nails are predefined by the molded recesses, since the dimension of the backing die opening is substantially greater than the transverse dimension of the plunger, and since the dimension of the predefined nailheads is intermediate the substantially dilferent dimensions of the backing die opening and the plunger, fracturing of the strip at the weakening and head defining recesses therein is assured to provide for the accurate severence of uniform predefined headed nails from the strip, and this is so even though there might be some inaccuracies in the indexing of the strip as it is advanced in the nailing machine. Since there is no shearing or punching by the backing die and plunger, they will have substantially no wear and have substantially infinite life which is not the case where shearing or punching is involved.
The nail shanks are preferably integrally molded with the strip and its weakening and nailhea-d defining recesses in a single operation, and while various molding methods may be utilized, particularly good results have been obtained by die casting the nailing strip in die casting molds and utilizing zinc or the like as the cast material which readily fractures at the weakened and head defining recesses in the strip. If desired, the molded headed nails may be reinforced with headed reinforcing nails which are embedded in the nailing strip during the molding operation. The molded weakening and head defining recesses need only extend partially through the molded strip, but it has been found advantageous to have portions of the recesses extending completely through the strip, particularly those portions of the recesses which are arranged between the nail shanks and which cooperate with the indexing stop of the machine for indexing the advance of the nailing strip in the machine. Preferably, the nail shanks extending from the nailing strip are roughened to increase their holding power when driven into an object, particularly good results being obtained when the roughenin-g is accomplished by sandblasting or mechanical scoring.
Further objects of this invention reside in the construction of the nailing strip, the construction of the backing die and plunger arrangement of the nailing machine and in the cooperative relationships between the same.

Referring first to FIGS. 1 to 7 of the drawings, one form of the nailing strip of this invention is generally designated at 10. It includes an elongated molded or die cast strip 11 having substantially parallel side edges 12 and 13. A plurality of pointed nail shanks 14 extend from one face of the strip 11 intermediate the side edges 12 and 13 and in spaced apart relation along the strip. These pointed nail shanks 14 are preferably molded or die cast integrally with the strip 11 in a single molding or die casting operation. Recesses 16 and 17 are molded in the strip 11 about each nail shank 14 to weaken the strip 11 thereat. It is here noted that the arcuate recesses 16 which are between the nail shanks 14 and the side edges 12 and 13 of the strip 11 extend only partially through the strip 11, while the double arcuate recesses 17 between the nail shanks 14 extend completely through the strip 11. The recesses 16 and 17 define the outlineof a nailhead 15 for each nail shank 14.
Referring now to FIGS. 8 to 10, a mold for molding or die casting the nailing strip is shown at 20. It includes a plurality of holes 21 which operate to form the nail shanks 14. Arranged around each hole 21 is an annular recess 22 which forms the bottom surface of each nailhead 15. Around each recess 22 laterally of the hole 21 is a pair of arcuate bosses 23 which operate to form the recesses 16 in the nailing strip. It is noted that these bosses 23 extend only part way up to the top surface of the die 20 so that the recesses 16 in the nailing strip 11 formed thereby extend only partially through the nailing strip. The annular recesses 22 are also provided with arcuate bosses 24 between the holes 21, which bosses extend up to the top surface of the mold 20. These bosses 24 form the recesses 17 in the nailing strip 11 and since the bosses 24 extend to the top surface of the mold 20 the recesses 17 in the strip 11 extend completely through the strip 11. The mold 20 also is provided with a pair of elongated recesses 25 laterally from the bosses 23 and 24, these elongated recesses 25 forming the sides of the nailing strip 11 with the side edges 12 and 13. Molten-material, such as a zinc alloy or the like, is poured into the mold 20 to the top surface thereof and is allowed to cool and solidify therein, and when the solidified material is removed from the mold .2 it forms the mailing strip 4 generally designated at 10 in FIGS. 1 to 7. It is here noted that the holes and recesses in the mold 20 have a taper so as to permit ready removal of the molded or die cast nailing strip 11 therefrom.
The manner in which the nailing strip cooperates with the backing die and the plunger of a nailing machine for severing and driving headed nails from the nailing strip is illustrated in FIGS. 4 to 7. Here the nailing machine, which may be of the type disclosed in my copending application, S.N. 211,551, filed July 23, 1962, issued as Patent No. 3,211,352 on Oct. 12, 1965, includes a backing die 30 provided with a relatively large opening 31 extending therethrough. The backing die 30 is also provided with a feed slot 32 so as to allow the nail shanks 14 of the nailing strip to enter the die opening 31. The backing die 30 also includes guide portions 33 for engaging the side edges 12 and 13 of the nailing strip for guiding the same through the backing die 30. The nailing machine also includes an indexing stop 34 for successively engaging the predefined nailhead por tions 15 of the strip 11 to index the nailing strip 10 through the nailing machine. Means such as disclosed in said Patent No. 3,211,352 are provided for advancing the nailing strip 10 through the nailing machine. The nailing machine also includes a plunger 35 concentrically arranged with the backing die opening 31, the plunger 35 being reciprocated up and down.
It is here noted that the opening 31 in the backing die 30 is substantially larger than the dimension of the nailhead 15 defined by the recesses 16 and 17 in the nailing strip and that the plunger 35 has a transverse dimension which is substantially less than the dimensions of the predefined nailhead 15. As a nailing strip 11 is fed between the backing die 30 and the plunger 35, as illustrated in FIGS. 4 and 5, the'first predefined nailhead 15 in the strip engages the indexing stop 34 so as to centrally locate the same with respect to the die opening 31 and the plunger 35. As shown more clearly in FIGS. 6 and 7, the plunger 35 engages the predefined nailhead 15 and forces the same downwardly whereupon the nailing strip is fractured at the recesses 16 so as to sever and drive predefined headed nails from the nailing strip. Because of the relative dimensions of the backing die opening 31, the predefined nailhead 15 of the headed nail and the plunger 35, the severance of the headed nail from the nailing strip is not brought about by shearing or punching but, is brought about by fracturing the nailing strip at the weakening and nailhead defining recesses '16. After the first headed nail is driven from the strip 11 and the plunger 35 retracted, the strip advances to a position where the next predefined headed nail engages the indexing stop 34 so as to be concentrically arranged with respect to the backing die opening 31 and the plunger 35, ready for being severed and driven by the plunger 35 in the manner described above.
FIGS. 11 and 12 illustrates the headed nails after they have been severed and driven from the nailing strip. They also show the roughening of the nail shanks 14 which operates to increase the holding power of the nails. In FIG. 11 the roughening of the nail shanks has been accomplished by sandblasting as illustrated at 37, and in FIG. 12 the roughening has been accomplished by mechanical scoring of the nail shanks as indicatedat 38. Of course, the roughening of the nail shank 14, either by sandblasting or by mechanical scoring, is done following the molding or die casting of the nailing strip and prior to use of the nailing strip in the nailing machine.
Another form of the nailing strip of this invention is generally designated at 40 in FIGS. 13 to 15. Here, the molding strip 40 includes a molded or die cast strip 41 having side edges 42 and 43, and a plurality of pointed nail shanks 44 extend from one face of the strip 41 intermediate the side edges thereof and in spaced apart relation along the strip. The nail shanks 44 are provided with predefined nailheads 45, which are predefined by recesses 46 laterally of the nail shanks and recesses 47 between the nail shanks. The recesses 46 extend only partially through the strip 41 while the recesses 47 extend completely therethrough.
The nailing strip 40 is fed into a nailing machine having a backing die 50 provided with an opening 51 and a slot 52 to allow feeding of the nailing strip thereto. The backing die 50 is also provided with guide surfaces 53 to be engaged by the side edges 42 and 43 of the nailing strip for guiding the nailing strip. The nailing machine also includes an indexing stop 54 and a reciprocatable plunger 55. Here again, the dimensions of the backing die opening 51 are substantially greater than the dimensions of the nailhead 45 predefined by the recesses 46 and 47, and the dimensions of the plunger 55 are substantially less than the dimensions of the predefined nailhead. The manner in which the predefined headed nails of the nailing strip 40 are fractured at the recesses 46 and severed and driven from the nailing strip is indicated in FIG. and it is substantially the same as that described above in connection with FIGS. 1 to 7, and accordingly, a further description is not considered necessary. The nailing strip 46 is molded or die cast in a suitable mold in substantially the same manner as described above in connection with FIGS. 8 to 10. Of course, the mold cavities are somewhat difierent so as to provide the shape of the predefined headed nails as illustrated in FIGS. 13 to 15. The shapes of the predefined nailheads of the nailing strip 40 are somewhat different than those of the nailing strip 10, and by reason of the arrangement of the nailing strip 40 it can contain more nails in a given length than in the nailing strip 10.
Another form of nailing strip is generally designated at 60 in FIGS. 16 to 18. Here the nailing strip includes a molded or die cast elongated strip 61 having substantially parallel side edges 62 and 63 and a plurality of pointed nail shanks 64 extending from one face of the strip intermediate the sides edges and in spaced apart relation along the strip. The nailing strip is provided with recesses 65 laterally of the nail shanks 64 and recesses 67 between the nail shanks 64 for weakening the nailing strip and predefining nailheads 65 for the nail shanks 64. Here the predefined headed nails are reinforced with reinforcing nails having shanks 68 and heads 69, the reinforcing nails being formed of steel or the like. The reinforcing nails are embedded in the nailing strip during the molding or die casting thereof, they being suitably suspended in the recesses and holes in the mold during the molding or die casting. Here, as in the previous forms of the invention, the recesses 67 between the predefined nailheads 65 may extend completely through the strip 61. The nailing strip is fed into a nailing machine which may be like that described above in connection with FIGS. 13 to 15 and, accordingly, like reference characters for like parts have been utilized. The manner in which the predefined nailheads 65 are fractured at the recesses 66 and in which the reinforced and predefined headed nails are severed and driven from the nailing strip are substantially the same as described above and, accordingly, a further description is not here considered necessary.
Still another form of nailing strip of this invention is designated at 70 in FIGS. 19 to 22. Here, the nailing strip 70 includes an elongated molded or die cast strip 71 having substantially parallel side edges 72 and 73 and a plurality of pointed nail shanks 74 extending from one face of the strip intermediate the side edges thereof and in spaced apart relation along the strip. Recesses 76 are molded in the strip laterally of the nail shanks 74, recesses 77 are molded in the strip intermediate the nail shanks 74 and recesses 78 are molded in the nailing strip between the recesses 76 and 77, all of said recesses 76, 77 and 78 operating to weaken the nailing strip thereat and to predefine integral nailheads 75 for the nail shanks 74. The recesses 76 and 77 extend only part way through the strip 71 while the recesses 78 extend completely therethrough.
6 The nailing strip 70 is fed into a nailing machine having a backing die 80 provided with a relatively large opening 81 and with a slot 82 for accommodating the nail shanks 74 as the nailing strip is advanced. The backing die 80 is also provided with guide surfaces 83 which are engaged by the side edges 72 and 73 of the nailing strip for guiding the nailing strip as it is advanced. The nailing machine also includes an indexing stop 84 which engages the predefined heads 75 of the nailing strip. Herealso, the dimensions of the die opening 81 are substantially greater than the dimensions of the predefined nailheads 75 and the dimensions of the plunger 85 are substantially less than the dimensions of the predefined nailheads 75. When the plunger 85 is advanced, as illustrated in FIGS. 21 and 22, the nailing strip is fractured at the recesses 76 and 77 so as to sever and drive predefined headed nails from the nailing strip substantially as described above in connection with the other forms of this invention. Since both the recesses 76 and 77 extend only part way through the strip 71, it is preferable to utilize the recesses 78 which extend completely through the strip 71 so that there is a clean fracture of the nailing strip at the corners of the predefined heads 75 of the nails.
While for purposes of illustration several forms of this invention have been disclosed, other forms thereof may become apparent to those skilled in the art upon reference to this disclosure and, therefore, this invention is to be limited only by the scope of the appended claims.
