MACHINES FOR MAKING SPIKE-S.
Patented Aug.1,1876.
4 l Hl Ill!" UNETED S'rMrEsA PATENT OFFICE.
GEORGE N. SANDERS, OF NEW YORK, N. Y.
IMPROVEMENT IN MACHINES FOR MAKING SPIKES.
Specification forming part of Letters Patent No. 180,648, dated August 1, 1876 application filed.Y January 3, 1876.
To all whom lit may concern:
Beit known that I, GEORGE N. SANDERS,
' of N o. 39 Nassau street, city of New York, N.
Y., have invented the Improvement in Spike Machinery for Making the Patent Curve- Spikes, of which .the following is the specilication:
Referring to the accompanying drawing, Figure 1 represents that portion of the spike 'machinery in which the-improvements are made; Fig. 2, a section formed by passing a plane transversely through the rolls at the point Where the spike passes through, show-v ing the formation of the dies a a b b, Which shape the point of the spike, and ot' the grip- -l and 2, (turning in the direction indicated by the arrows c c.) The dies a a correspond in shape to the die C used for finishing the upper side of the spike E, Fig. 3, and the diesb b to the`die D, used for finishing the lower side of the spike E, makingthe proper allowance in the form ot' the dies for their being on the periphery of' the rolls, and for the drawing or elongation of the spikerod or blank at the part d d, Fig. 3, in pressing through the rolls A B. After going through the rolls A B, where the shank or body is shaped and pointed, the spike-blank is passed into the griping and finishing dies() D, which press the shank and point into perfect shape, correcting any irregularities ot' the rolls; and at the same time holding the blank as gripers until the header strikes the other end, and forms the head in the usual manner. It is immaterial Whether A orB be made the upper roll, or whether they are operated vertically or horizontally, as long as C is made to correspond with A, bearing the dies a, and D to correspond with B, bearing the dies b; and as to the number of dies, that varies, of course, with the size ofthe rolls. The Walls projecting up beside the eccentrics, to keep the iron from spreading while passing through the rolls A B, are ot' the forms now in use in the various machines to which the invention herein described is applicable.
I claim as my invention- The combination of the rolls A B, carrying the preparatory dies a b, with the dies O D, shaped, as described, so as to compress and finish the spike, both body andA point, and
hold it whilev being headed, 'substantially as and for the purpose set forth.
In witness whereof I havehereunto set my hand in the presence of two witnesses this 31st day ot' December, 1875.
GEO. N. SANDERS.-

LEWIS SANDERS, E. J. E. ScHREcK.
