Description

and length, forming what JOHN L. KRAUSER, OF READING, PENNSYLVANIA.

MANUFACTURING NAILS.

Specication of Letters Patent No. 21,005, dated July 27, 1858i.

T0 all eli/0m t 'may concern.'

Be it known that I, JOHN L. KRAUSER, of t-he city of Reading, in the county of Berks and State of `Pennsylvania, 'have invented certain new and useful Improvements in Nail-Plates for the Manufacture of Improved Cut Nails; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to t-he letters of reference marked thereon.

The object of my invention is the production of an improved point upon that description of cut nails whose two rolled sides are parallel, and whose cut faces are tapering from head to point. Its nature consists in so beveling the edges of nail plate that the blanks cut therefrom will be tapering or V shaped at both ends; the head being formed by driving the heading tool against the widest of the tapering extremities; the details being as hereinafter set forth.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The usual method of preparing' nail plates for the production of cut nails consists in introducing to a shears of the requisite form and construction, a sheet of metal of any length, it being of the requisite thickness, and breadth, from which by a transverse cut, are severed strips of the required width., is commonly termed the nail plate, such plate being uniformly produced with (practically speaking) square edges, and from which are afterward cut the blanks, which when headed, form the well known cut nail, with blunt ends or extremities.

The object of my improvement is so to prepare the plate, that when the blanks are cut therefrom, and headed the same shall be pointed without further process. To accomplish this I prepare the plate with tapering or V shapec edges as indicated by letters e, c, Figure l, which is an end view ofthe improved plate taken through the dotted lines cz, a, in Fig. 2, which latter figure is a perspective view of the improved plate. It will be observed that if the tapering edges c1, c2, Fig. 2, of the plate be made continuous on both sides of the plate, that the blanks, F 4; and 5, cut threfrom will previous to the heading thereof, be wedge or V shaped at both extremities, 1, so that in the process of heading the same, the heading tool must act against the wedge, b1.

The object of my improvement therefore has reference to the production of cut nails and spikes which shall be provided with tapering, wedge or V shaped ends or extremities and which is accomplished by treating the nail plate in manner as hereinbefore explained.

This method of forming cut nails with sharp points differs from that employed in making horse shoe nails, as the plate in that case is rolled to a sharp edge on one side only, the two faces inclining to each other for that purpose. This process differs also, from the manner of pointing shoe pegs; there being no heading there, and all the opposite sides parallel.

I do not claim rolling nail plate to an edge on one side by inclining its faces as is practiced in making horse-shoe nail blanks; nor, do I claim sharpening a single et ge, as in the strips of wood from which shoe pegs are split, as my invention is altogether distinct from these cases; but

That I do claim and desire to secure by Letters Patent, is*

The process as herein set forth, of making cut nails with improved points; that is to say-beveling both ec ges of the nail plate so that the blanks shall be wedge shaped at both ends, as shown in Fig. 2, and forming the head by the action of the heading tool against the widest end of the blank, as hereinbefore set forth.
