Description
JOHN MCGRONE, OF ELLICOTTS MILLS, MARYLAND.
MACHINE FOR MAKING WR-OUGHT NAILS AND SEIKES.
Specification of Letters Patent No. 1,497, dated February 21, 1840.
A, is a pulley whirl on the main shaft B, from which the movements of the operating parts of t-he machine are derived.Y The spikes are to be made from heated rods,
which are fed in at the front of the machine,
where the piece necessary for one spike is cut off, gripped in dies so as to form the point, and headed by a sliding punch. The rod is passed along over the part marked C, until its end is received against the strip D, when it is cut o, and received by the gripping dies.
E, is a lever which is moved laterally by the cam F, the fulcrum of which is at G. This lever advances the cutter H, which operating against cutter I cuts the rod, and pushes the piece forward to be operated on by the gripping dies. J, is a lever acted upon laterally by the cam K. This lever carries the slideM, having on it the lateral gripping die N, which grips the piece against the stationary, lateral die at O. The lever P, which has its fulcrum in the standards Q, Q, is moved vertically by a cam. This lever carries the gripping die S, which grips the piece against a stationary die below it, and, by a concurrent action with the lateral dies, give the taper and point to the spike. While thus gripped, the heading die is slid up by the following means: T, is a crank on the end of the shaft B connected to the lever U, by the shackle V. This lever, as it rises and falls, works the rocking shaft W, a driver X, attached to which moves the slide L, of the heading die L. This arrangement is most distinctly shown in Fig. 2.
When the forming and heading of the spike has been effected in the manner described, the respective cams, operating upon the levers of the gripping dies, cause them to recede; this being, in the laterally worked levers, effected by the form of the eccentric grooves, or cams, but in the vertical lever P, it is effected by the iron strap Y, Y, surrounding the cam below the lever. When the spike is thus relieved from the pressure of the dies, it lies upon the lower, and against the side, stationary dies, from which it is to be removed, which is effected by what Idenominate fingers, or clearers. This apparatus is shown at Z, Z; it consists of a double forked, o-r otherwise convenientlyformed, p
piece of iron, attached at one end to the lever Z2, which is worked laterally by a Cam on the shaft B, inthe same way as the levers E, and J, are worked. The ends of the fingers are bent down at right angles at Z1, the two descending ends being received into recesses made for the purpose in the stationary, lateral die. At the instant when the spike is relieved, the lever Z2 moves forward, and the fingers push it offl from the lower stationary die, causing it to fall under the machine. Fig. 3, shows the fingers separate from the machine. Fig. 4 the main, or cam shaft.
When it is desired to make brad headed spikes, it is necessary to bend the top of the piece to be headed over on one side before the heading die is brought down upon it, as without doing this a good brad head cannot be formed; and this I effect by the act-ion of the lever U, as shown in Fig. 5, which represents such a part of the side of the machine as is necessary for the purpose. a, a, is a lever working on a fulcrum at and carrying a bolt, or set, '0, at its upper end, which is forced forward by the spring el, andpassing through the headblock e, bends the upper end of the spike rod as required. The set rod c, is withdrawn by the descending of the lever U, before the heading die descends, which die, of course, is so formed as to produce a good brad head. The spring d, may be omitted, and the forcing forward of the set c, may be effected by the raising of the lever U, the lever a, 0;, being so formed Q. l I V17,497
