NAIL-PLATE, AND our NAIL.

SPECIFICATION forming part of Letters Patent No. 363,866, dated May 31, 1887.

Application filed November 11, 1885. Serial No.1F2AE9.

To all whom it may concern.-

Be it known that I, GEORGE T. WALKER, of Napa City, in the county of Napa and State of California, have invented certain new and useful Improvements in Nail-Plates and Cut Nails; and I do hereby declare that the following is a full, clear, and exact description of the invention, 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 the letters of reference marked thereon, which form part of this Specification.

My invention relates to cut nails and the plate from which they are cut; and the improvements in which my invention consists, and which I shall now proceed to fully describe, and specifically point out in the claims, are intended especially for application to out steel nails, which are now rapidly taking the place of iron out nails in the markets of the world. These steel nails are open to objections, the most prominent being that they are very smooth, and consequently do not possess nearly the holding power of the iron nail.

WVith the object in view of remedying this and other defects I have constructed my improvement, which I illustrate in the accompanying drawings, in which- Figure 1 is a view in perspective of a nailplate'construeted according to my invention. Fig. 2 isa top plan view of a portion of such a plate, showing the lines on which the nails are cut. Fig. 3 is a view in side elevation of my improved nail. Fig. 4. is a perspective view thereof, and Fig. 5 is aview of a modification.

Like letters of reference mark the sameparts in all the figures.

Referring to the drawings by letters, A is the nail-plate, which is of the width from side to side of the length of the nail to be out therefrom, with the addition of the thickness of the head of the nail. In manufacturing this plate I indent, serrate, or groove it at intervals on one or both sides, as at a, thegrooves, indentations, or serrationslyinglon gitudinall y of the sheet or plate, so that they will be transverse to the nails cut from the sheet, and,when formed in each side of the plate, are made to alternate with each other, so as to prevent too great aweakening of the nail. On each side of the plate I form, by any well-known means,

(No model.)

or by improved means for which I contemplate applying for Letters Patent, a thickened rib,'A, which forms the heads of the nails. These grooves, serrations, or indentations may be made in any nail-plate; but the nail-plate I show is especially designed for nails such as I illustrate in this application, which nails are provided with wedge-points, being cut from the plate on the line shown in Fig. 2. In this the line b shows the division between the heads of the two adjoining nails. From inner end of this line the lines e e deflect in opposite directions, showing between them the shape of thewedge-point of the nail.

From the inner extremity of each of these lines extends-a line,

d, which shows the side or edge of the nail.

The nails being cut with the heads of alter-' nate nails adjoining, brings the point of each intervening one between these heads, as shown in this figure, and the description of the'lines one side will sufficc for both. When the nails are cut on these lines that is to say, by cutas atff in Figs. 3 and 4..

The nail thus constructed. possesses many advantages over those heretofore made. The serrations cause them to hold firmly in the wood. The wedge-point, as well known, facilitates driving, and the serrations may be made by other means, notably by means of ridges in the cutters, on the edges of the nail, as shown in Fig. 5.

Although I have described the plate as having serrations, grooves, or indentations longitudinally thereof, I do not wish to be understood as limitingmyself literally thereto. The term longitudinally is'used to designate that dimension of the plate the line of which is at right angles to the length of the nail.

I desire, further, to state that I do not limit myself to straight-line grooves or indentations, but hold that the spirit of my invention in-,

cludes lines of any direction, either'straight or curved, which will accomplish the object in view-via, to serrate the cut nail, brad, or

1. A nail-plate having a rib along each of .two opposite edges to form the heads of nails to be cut therefrom and provided with grooves on its face, the grooves having the same general direction as the ribs, the plate being a nails length plus the thickness of a nails head in width, substantially as set forth.

2. The nail -plate having ribs extending along each of two opposite edges, projecting from the opposite faces of the plate, and longitudinal grooves extending along the opposite faces of the plate, the distance from the extreme outer point of each ribbed edge to the inner face of the rib on-the opposite edge being a nails length, substantially as set forth.

3. A cut nail provided with grooves across its'body and a head projecting from its nongrooved sides, substantially as set forth. 7

4. A cut nail provided with grooves across its bod y,and having a head projecting from all sides of its body, substantially as set forth.

5. A cut nail provided with grooves across its body,and having its non-grooved sides beveled at the point, substantially as set forth.

1 6. A cut nail provided with grooves across its body, and having its point beveled on all sides, substantially as set forth.

In testimony that I claim the foregoing as my own I hereunto aflix my signature in pres enee of two witnesses.

GEORGE T. W'ALKER.
