IMPROVEMENT IN HORSESHOE-NAIL PLATES.

Specification forming part of Letters Patent No. 184,089, dated November 7, 18.76 application tiled September 21, 1876.

To all whom it may concern:

Be it known that I, JOSEPH M. LAUGHLIN, of Boston, in the county ot Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Horse Nail Plates; and I do hereby declare that the following` is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in nail-plates for the manufacture of horseshoenails; and consists in providing a nail-plate with a succession of depressions or indentures, which l make either by removing a portion ot' the stock, or by subjecting the plate to pressure between a pair of rolls, or by blows, or otherwise. The said indentures or depressions serve for the purpose of forming the point or bevel of the end of the nail when punched from the nail-plate.

vThe advantage of this improved nail-plate over the patent granted on the 2d day of February, 1875, (No. 159,410,) to D. J. Harrington, in which a continuous groove is formed for the formation of the bevel or point of the nail when punched from the plate, is that less power is needed to produce the aforesaid indentures or depressions than to form a continuous groove,.whether it is produced by the removal of the stock, or by pressure between rolls, or by blows, or otherwise.

Another advantage is that when the said indeutures are arranged in two rows, as represented in Fig. l, I am able to make longer nails with less stock and less waste than could be done-according to said Harringtons patent, owing to the fact that each nail when punched overlaps the opposite one as much as the distance between each row of indentures or depressions in the direction of the length of the nails.

On the accompanying drawings, Figure l represents a plan view of my improved nailplate. Fig. 2 represents a cross-section on the line A B. (Shown in Fig. 1.) Fig. 3 represents a modicationof my improved nailplate, and Fig. 4 represents a cross-section on the line O D. (Shown in Fig. 3.) Fig. 5 also represents another modification of my improved nailplate, and Fig. 6 represents a cross-section on the line E F. (Shown in Fig. 5.)

, Similar letters refer to similar parts wherever they occur on the dilferent parts of4 the drawings. I

a a represent the nailplate, provided with` ridges or projections b b on one or both sides, as shown in the drawings. c c c c represent depressions or indentures for the purpose of forming the point or bevel of the nails d d d, when punched from the said nail plate. In Fig. l, the depressions or indentures c c c are shown as located in two rows, each depression in one of the rows being located between two successive depressions in the opposite row. It will be seen, by reference to said Fig. 1, that the nails d d d project beyond each other, from opposite sides, in the direction ot' the length ot' the nail, a distance equal to the distance between the middle of each .row olf depressions c c c. This is very advantageous, as by so doing I am able to produce longer nails from a less amount of stock and with less waste than by using only one single row of depressions, as shown in Fig. 3.

However, for certain kinds of nails it may be desirable to cut the nails out from a nailplate, as shown in Fig. 3, in which one single row of depressions is made,- and in which the nails are punched out directly opposite each other in rows, as shown.

Fig. 5 shows a nail-plate of a width equal to thelength ot' one single nail only, and. having, in consequence, the depressions c c located on the thin edge of the plate. Another modification (not shown in the drawing) is. making a plate ot' twice the width, as shown in Fig. 5, and having a ridge or projection in the middle, and provided on two opposite sides with depressions orindentures for the formation ofthe bevels or points-in fact making a nail-plate of ldouble'the width, as shown in Fig'. 5, with a ridge or projection in the center for the formation of the heads ofthe nails, and having OR TO JOHN i depressions or indentures on two opposite' my invention, I Wish to secure by LettersV Patent, and claim- A nail-plate, provided with a series of indentures or depressions, c c c, for the formation of the bevels or points ofthe nails when punched therefrom, substantially as herein set forth and described.

In testimony that I claim the foregoing as my own invention I have aiiixed my signature in presence of two witnesses.

-Y JOSEPH M. LAUGHLIN.
