NAIL OR SLUG STRIP.

SPECIFICATION forming part of Letters Patent No. 610,475, dated September 6, 1898. Application filed March 23, 1896. Serial N0. 584,366. (No model.)

To ctZZ whom it may concern.-

Be it known that I, SOLOMON M. CUTTER, of Nashua, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Nail or Slug Strips, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in nail or slug strips.

It has for its objectito provide a nail or slug strip in which the nails or slugs cut therefrom have the exposed surfaces of their heads when driven of various shapes; also, to form the head-forming portion of the strip with indentations between the'heads of two adjoining nails or slugs in said strip, which indenta-` Y tions extend below the surface of the shankforming portion of the nail-strip, so that the heads of the nails or slugs to be formed from the strip are nearly severed from each other, leaving a very thin web to join said heads together, said nails or slugs being joined t0- gether in a continuous strip by means of a small portion of the shank-forming portion of the strip, by which construction said nails or slugs are easily detached from the strip in the machine in which they are used and the heads of the nails so' detached are more perfect in form.

The invention is carried out substantially as illustrated on the accompanying drawings, which form anessential part of this specification-and whereon the nail-strip and the blank for the formation of the same have been shown as forming diamond-shaped exposed portions of the head; but other-shaped heads may be made, if so desired. f

On said drawings,Figure l represents a plan view of the blank for the formation of the nail or slug strip, showing the same partly divided into two continuous nail or slug strips. Fig. 2 represents a side elevation of the same. Fig. 3 represents a cross-section of the blank.

Likecharacters of reference refer to like parts wherever they occur on the different parts of the drawings.

The blank is made in the form of a metal strip or tape, having the body portion 1 and the longitudinal ribs 2 2, preferably on both edges of the strip and on both sides thereof, which ribs are provided with indentations 3 3, as shown, the indentations on each side extending below the surface of the body portion of the blank and preferably so that they nearly meet the indentations on the other side of the blank, as shown in Fig. 2, thus nearly severing the longitudinal rib at intervals. The metal blank, as above described, is separated into two continuous nail or slug strips, the indented longitudinal ribs forming an indented head-forming portion on the strip, and the body portion l of the blank being separated, so as to form projecting comb-shaped shank-forming portions 4 4L on the strip, substantially as shown on the drawings, being joined together by a small portion of said shank-forming portion directly under the head-forming portions. It is, however, unnecessary that the shape of the indentations 3 or the shank-forming portions 4. should be that shown on the drawings, as either or both may be varied, 'as desired, so as to vary the shape of the nails or slugs cut therefrom, and I do not wish to confine myself in this respect to any particularshape of either the head or shank forming portions of the strip.

In using a continuous Anail or slug strip in a machine in which the nails or slugs are severed from the strip by inserting a cutter between the shank forming portions of the strip and forcing the cutter upward through the continuous part of the strip or by forcing the strip vdownward against the cutter it has been found that the edges of the heads of the nails or slugs where theyl are severed from the strip are turned upward,forming a bur' tically to amount to nothing, but that the top of the head of the nail or slug will be substantially flat. It has also been found when the indentations in the head-forming portions have been made below the surface of the shank-forming portions, nearly severing the head-forming portion, and it is desired to make diamond-shaped heads, as shown on the drawings, or to make triangular star-shaped or heads of any other pointed design, that the heads of the nails or slugs so formed are more perfect in shape, as the points of the design of the head will be points and not be cut off square.

My improved nail-strip is designed more especially for the purpose of nailing the soles or slugging the heels of boots and shoes, and the use of my strip lessens the Work of scouring the soles or heels, as well as adds to the appearance of the work when done.

Itis not essential to my invention that I should use a blank having an indented longitudinal rib on both edges of the same and should separate such a blank into two continuous nail or slug strips, as described, as I might use a blank having an indented longitudin-al rib only on one edge thereof to form a single continuous nail or slug strip from the same without departing from my invention.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- A nail or slug strip, consisting of combshaped shank-forming portions, a continuous headaforming portion, a longitudinal rib on each side of the continuous head-formin g portion, indentations in said ribs on the opposite sides thereof in line with t-he spaces between the teeth of the shank-forming portions and extending below the surface of the shankforming portions leaving very thin metal joining the head portions so formed, and a continuous portion of the shank-forming portion immediately under the head portion joining the shank portions of even thickness with the shank portions and having unbroken surfaces on both sides, for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 18th day of March, A. D.-1896.

SOLOMON M. CUTTER.
