@uiten tatie @auch @ffice IMPROVED NAIL MACHINE.

TO ALL WI-IOM IT MAY CONCERN:

Be it known that I, JOHN M. ALLEN, of Cambridge, in the State -of Massachusetts, have invented an Improved NailvMachine; and I do hereby dez-lare the following to be a full and correct description of the same, reference being had to the accompanying drawings, in which- I Figure 1 is a. perspective view of the machine.

Figure 2 is a'vertical section of the rollers.

Figure 3 is a. view of the nail cnt by the machine.

The same letter marks the same part wherever it occurs. Y y

The nature of this invention consists in the constrhction of a machine for cutting nails Without waste-from plate or-sheet metal, in whichthe ribs and recesses, which constitute the nail-cutting dies, are formed longitu-l dinally on the surfaces of a pair of rollers, occupying the whole of those surfaces, the rib on one roller corresponding to the recess on thc othcigso as to cut up the 'tvhole of the plate into nails; 'th-e dies being arranged head to point, and a. recess for forming the heads ofthe nails eing left at either end of the rollers, all as hereinafter more specifically setforth.

To enable others 'to make and use my improved nail machine, I will proceed to describe its construction and operation. y l

In tht-.accompanying drawing marks a stout frame of iron, in which the rollers are hung in the usual way; B marks a winch, which indicates the point oi' application ofthe power of any suitable prime jnover; C Cf are friction or gear-wheels on theends of the journals of the rollers, and by which they are driven. D D are the rollers, on whose surfaces are formed' longitudinally, as shown, the ribs and recesses a a." b b', which constitute the nail-cutting dies, the recesses being of such depth that when the rollers come together, at any given point, there isjilst room for a finished nail between the face of the rib and the bottom of the recess, as shown in iig. 2. The rollers are of steel or chilled iron, and the edge.; Aof the ribs aremade sharp to act likeshears in cuttingup the metal. A recess at either end of each roller is provided for the heads of the nails, which are divided by chisels xed in the end recesses for that purpose. A

The plate or sheet to be cut into nails is of the width equal to the length ei' the rollers, and, being passed in between them, is, by their rotation, cut into nails without waste. t

I am aware that nails have been formed in dies on the surfaces of a pair of rollers, as in Schueblys machine but the dies are arranged' in entirely a different manner, and do not operate on the same principle as in my machine. A

Having thus fully described my invention, what I-claim, and desire to secure by Letters Patent, is- A machine for cutting nails, without waste, from plate or sheet metal, in which-the dies are formed longitudinally on the surfaces of therollers, in the manner and for thepurpose described.

.The above specification of my said invention signed and witnessed at Boston this 9th day of August, A. 111867.
