Filed July 23, 1962 J6 JIZ United States Patent 3,211,284 NAILING STRIP Edgar P. Anstett, 21 Lakewood Place, Highland Park, Ill. Filed July 23, 1962, Ser. No. 211,733 Claims. (Cl. 206-56) 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 nail ing machine disclosed in my copending application Ser. No. 211,551, filed on even date herewith, wherein conventional headed nails are utilized, wherein the headed nails are supported by an elongated strip which frictionally grips the shanks of the headed nails and which is readily severed by the nailing machine, wherein those portions of the strip which are severed and driven with the nails form a weather tight seal for the severed and driven nails, and wherein the nailing strip may be readily and inexpensively produced on a high rate production basis.

Briefly, the nailing strip of this invention preferably includes an elongated molded resilient synthetic plastic supporting strip having a plurality of centrally arranged and longitudinally spaced apart substantially cylindrical resilient nipples extending from one side of the strip and a plurality of nail receiving openings extending through the strip and its nipples. A plurality of headed nails are inserted into and supported in longitudinally spaced relation by the strip and have their heads engaging the other side of the strip and their shanks extending through the nail receiving openings and resiliently gripped by the nipples. In addition, the shanks of the headed nails are preferably provided with barbs to increase the resilient gripping action between the nail shanks and the nipples of the strip. Also, preferably the strip is provided on its said other side with a plurality of recesses concentrically with the nipples for receiving the heads of the headed nails in countersunk relation. The strip is further preferably provided with transverse slots between the nail heads for indexing the nailing strip in the nailing machine.

The strip is shearable about each nail head through said slots so that the headed nails with the gripping nipples and the portions of the strip underlying the nail heads may be sequentially severed and driven into the work from the nailing strip by the nailing machine. The severed portions of the synthetic plastic strip which are driven into the work with the headed nails form a weather tight seal for the headed nails, this being particularly desirable for roofing purposes and the like.

In the manufacture of the nailing strip of this invention, the elongated resilient synthetic plastic supporting strip, with its nipples, recesses, nail receiving openings and slots, is readily, rapidly and inexpensively molded by a suitable injection molding process or the like, and the headed nails, which may be conventional headed nails, are readily, rapidly and inexpensively inserted in the nail receiving openings in the strip by a suitable nail inserting apparatus. The nailing strip may be of any desired length for convenient handling and use in the nailing machine, as for example, about inches long and carrying about 33 headed nails. Any suitable syn- 3,211,284 Patented Oct. 12, 1965 ice thetic plastic material having the necessary toughness, resiliency and shearability may be utilized for the supporting strip, as for example, an acetal resin product such as Duponts Delrin or the like.

Further objects of this invention reside in the details of construction of the nailing strip, the cooperative relationships between the component parts thereof, and in the method of forming the nailing strip.

Other objects and advantages of this invention will become apparent to those skilled in the art upon reference to the accompanying specification, claims and drawings in which:

FIG. 1 is a top plan view of the nailing strip of this invention;

FIG. 2 is a side elevational view thereof;

FIG. 3 is an enlarged partial top plan view -of the synthetic plastic supporting strip forming a part of the nailing strip;

FIG. 4 is a longitudinal vertical sectional view through the supporting strip taken substantially 'along the line 4-4 of FIG. 3;

FIG. 5 is a transverse sectional view taken substantially along the line 5-5 of FIG. 3;

FIG. 6 is a transverse sectional view taken substantially along the line 6-6 of FIG. 3;

FIG. 7 is a top plan view similar to FIG. 3 but illus-,

FIG. 10 is a sectional view through a portion of a headed nail severed and driven from the nailing strip; and

FIG. 11 is a perspective view of a headed nail severed and driven from the nailing strip.

The nailing strip of this invention is generally designated at 10 in FIGS. 1, 2, 7, 8 and 9, the supporting strip thereof being illustrated in more detail in FIGS. 3 to 6. The composite nailing strip includes an elongated synthetic plastic nail strip 11 which is molded from any suitable synthetic plastic material such as described above, the molding being done by an injection molding process or the like. The synthetic plastic supporting strip 11 has a plurality of centrally arranged and longitudinally spaced apart substantially cylindrical nipples 12 extending from one side of the strip, the nipples 12 being formed during the molding operation. The other side of the strip 11 is provided with a plurality of recesses 13 concentrically arranged with the nipples 12, the recesses 13 also being formed during the molding operation. The strip 11 is further provided with transverse slots 14 which are arranged between the recesses 13 and the ends of the strip are provided with notches 20 which are positioned with respect to the recesses 13 in the same manner as the slots 14, the slots and notches also being formed in the strip during the molding operation. Nail receiving openings extend from the recesses 13 through the strip 11 and the nipples 12. These openings in the nipples 12, which are also formed during the molding operation, have a slight draft or taper which facilitates the molding of the strip and which aids in the gripping of the nail shanks received therein.

Referring now to FIGS. 7 and 8, the manner of inserting headed nails in the supporting strip 11 is illustrated. Here the shanks 15 of the nails are inserted through the nail receiving openings and the heads 16 of the headed nails are received in the recesses 13 in countersunk relation. The synthetic plastic nipples 12 resiliently grip the shanks 15 of the headed nails to support the headed nails in the supporting strip 11. This gripping action is enhanced by the aforementioned draft or taper of the nail receiving openings in the nipples 12 and also by barbs 17 formed on the nail shanks. Thus, the headed nails are firmly supported in the synthetic plastic supporting strip 11. The strip may have any desired Width depending upon the size of the headed nails and it may be of any desired length depending upon the number of headed nails supported thereby and the nature of the nailing machine in which the nailing strip is to be utilized.

Referring now to FIGS. 9 to 11, the manner of severing and driving headed nails from the nailing strip is illustrated. The nailing machine with which the strip is utilized includes die means for guiding and advancing the strip and the die means includes a projection 21 which is adapted to be engaged by the end notch 20 and subsequently by the transverseslots 14 for centering a headed nail under a blade 22. When the blade 22 is advanced, a headed nail is severed and driven from the nailing strip, and when the blade 22 is retracted, the nailing strip is advanced until the next slot 14 engages the projection 21 for centering the next headed nail to be severed and driven from the nailing strip. This operation is continued until all of the headed nails have been severed and driven from the nailing strip. It is here noted that the concave front of the projection 21 conforms to the contour of the advancing and retracting blade 22 and that the projection 21 accurately aligns each headed nail with the blade 22. The blade 22 shears the supporting strip 11 about the nail head and through the transverse slots 14 so that the scrap material of the strip 11 readily passes the projection 21 as shown in the left hand portion of FIG. 9.

In severing and driving the headed nail from the supporting strip 11 the strip is sheared about the nail head so that the headed nail carries with it the nipple 12 and that portion of the strip underlying and encompassing the nail head 16 as shown in FIGS. 10 and 11. This portion of the synthetic plastic strip 11 which is severed and driven with the headed nail is driven into the work along with the headed nail so as to provide a weather tight seal for the headed nail, this being extremely desirable for roofing purposes or the like.

While forpurposes of illustration one form of this invention has 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.
