IMPROVEMENT IN THE ART OF MAKING CHISEL-POINTE D NAILS.

Specification forming part of Letters Patent No. 165,380, dated July 6, 1875 application filed October 10, 1873.

To all whom it may concern Be it known that I, GEORGE STACY, of the city of Montreal, in the district of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in the Manufacture of Chisel-Pointed Nails; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention comprises an improvement in the art of manufacturing chisel-pointed nails by means of a single pair of cutting-dies, which can be substituted for the dies of an ordinary nail-cutting machine. These dies, having the configuration and structure hereiuafter set forth, operate upon a squareedged nail-plate, that is turned over after each cut, to be again operated on by the same dies. By

, this mode of proceeding, I manufacture chiselpointed nails, one at each movement of the dies, which require no heading or further finishin g, which are produced with great certainty, without creating waste or scrap, and Without the employment of complicated or cuinbrous machinery.

The manner in which my improvement in the art of manufacturing said nails is to be carried into effect will be understood by reference to the accompanying drawing, in which I have represented those mechanical parts which are particularly required in the practice of. my invention.

In the drawings hereunto annexed, where similar letters of reference indicate like parts, Figure 1 represents a view of part of the machine, showing the holding of the dies. Fig. 2 represents a plan of cutting-edges of cutting and bed die for cutting chisel-pointed nails. Fig. 3 representsthe finishing chiselpointed nail as cut from plate.

Letter A is the holder, of suitable size for holding the cutting-die. This is caused to move up and down to work with the bed-die, and is guided by any suitable guides, B. In. A is secured, by a set'screw, U, or in any other usual way, the cutting-die D. All so far described may be arranged as in any of the nail-machines at present in use, and the action of raising the cutting-die D and bolder A may be caused by any of the arrangements at present adapted for that purpose. The cutting-die D is of the configuration shown more particularly in Fig. 2, having inclined front 0 and bevels e and c and straight surfaces e and e, the head and point of the nail beingcut by the bevels e and 6 or the bevelse and e may be extended throughout the whole width. of the space occupied by them, and the surfaces 6 and e, if desired. F is the beddie, of corresponding configuration to D, but having its beveled sides set the opposite way. This will be at once understood by Fig. 2. The die F is secured to the bed G in any ordinary and suitable manner, or by setscrews H. Any ordinary and suitable stop will be arranged in the usual manner for gaging the proper amount of plate that is introduced at each cut of the machine. Fig. 3 shows the nail I, the plate from which they are cut, and the manner of cutting them. When the end of the plate K, which is of equal width and thickness throughout, is introduced between the cutters I) and F, the cut b is made, the piece a being waste. The plate is then turned over and the cut 0 is made, cutting 0d the first nail. In succession, the cuts d, e, andf(and.so on) are made, the plate being turned over each time, a nail being cut at each stroke, and no waste occurring between the nails The bed-die'must be provided with any ordinaryside stop or gage, to cause the plate K, when. turned over in the operation of cutting nails, to come to the proper lateral position on the bed-die; otherwise the action will be-very uncertain. The width of the plate K will, when made for cutting the nail I, (shown in Fig. 3,) be equal to or a little less than the width of the surfaces 0, e, and 0 but I do not confine myself to this, as it may be made a little wider, and extend upon the surfaces 0 and 6 Having described my invention, I desire to state, in conclusion, that I do not claim, broadly, cutting-dies having cutting-edges of the outline herein shown; nor do I claim, broadly, turning over a nail-plate after each cut, for the purpose of reversing the position of its out edge with respect to the cutting mechanism 5 but What I do claim, and desire to secure by squa-re'edged nail-plate that is turned over Letters Patent, is-- after each cut, to be again operated on by the The described improvement in the art of same dies, as and for the purposes set forth.
