UNITED STATES PATENT OFFICE.
DANL. DODGE, OF KEESEVILLE, NEW YORK.
NAIL-MACHINE.
Specification of Letters Patent No. 15,054, dated June 3, 1856.
T 0 all 'whom t may concern Be it known that I, DANIEL DODGE, of Keeseville, in the county of Essex and State of New York, have invented a new and useful Machine for Forging or Pointing Wrought Nails, Spikes, Sleigh-Shoes, Oarriage-Springs, and other Articles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a front elevation; Fig. 2, a vertical section through m of Fig. l, and Fig. 3 a plan View wit-h the shaft- B removed.
In these figures A A A is a frame of cast iron; B is a shaft driven by a belt on the pulley C; D is the anvil; E is a short arm fixed in the shaft B, direct-ly above this anvil, and having at its end the roller F; Gr G are two hammers, which face each other and work horizontally just above the face of the anvil D. They receive their motion from the cams H H bolted to the flanges I I between the journals of the shaft B. They are forced apart bythe spring K between them. The flanges I I are made to project somewhat beyond the cams for which they afford a seat, in order to serve the purpose of a fly wheel.
IVhen the shaft B revolves, the roller F passes so near the face o-f t-he anvil D as to act upon the bar of metal which is held on it by the operator, passing over it longitudinally from head to point of t-he article intended, `and reducing it to the proper vertical dimensions, the face of the anvil having its form so accommodated to the line in which this roller moves as to give the desired thickness to every part of the article produced. Its lateral dimensions are determined by the hammers G G which act simultaneously upon its opposite sides, and have their faces as long as the article desired and so formed as to give it the right width in every part.
Of course the cams H H and the arm E must be so arranged on the shaft that the roller F will alternate with the hammers in acting upon the metal. The rotary motion of the. roller upon its axis is caused solely by the friction of its surface against the metal in passing over it.
The spring L, seen in Figs. 2 and 8, but removed in Fig. 1 to show the anvil D, serves to raise the bar a little while the hammers act upon its sides, but yields so as to allow it to fall upon the anvil when acted upon by the roller.
The mode of operat-ing the machine is simply this. The shaft is put in motion and the end of a bar is introduced between the hammers by the operator, resting it upon the spring L, and pushing it forward until by the repeated act-ion of the roller and hammers it is brought to the requisite point and length, and is then withdrawn.
In addition to the above description I would remark, l, that it will not be found indispensable in all cases to have a roller in the extremity of the arm E. Instead of this, its extremity may be simply rounded or beveled, so as to produce upon the metal over which it passes an effect very similar to that of a roller; 2, that instead of fixing 'the roller in the arm of a revolving shaft, it may be attached to the connecting rod from a crank to a rocking shaft, or arranged in various other ways so as to serve the same purpose,
provided it be made to pass near the surface of a die or anvil, so as to act upon a bar when placed between reducing it to the proper thickness and taper. 3, that instead of the spring L to raise the bar from the anvil while the hammers act upon it, a small rocking shaft with an arm to support the bar may be employed, and a vibrating motion given to it by connecting it with a cam or eccentric on the driving shaft. 4, that some articles to the manufacture of which the roller and anvil are applicable do not require the action of side hammers to form them in the other directiol which may therefore be dispensed wit What I claim as my invention, and desire to secure by Let-ters Patent, is,
The use of the roller F, the anvil D, and the' hammers G G, constructed and operating substantially in the manner and for the purposes herein described, either in combination with the spring L or without it.
DANIEL DODGE.
