chine for making railway and other largespikes; and it consists in the certain details of construction and combination of parts, asV

will be fully described hereinafter.

In the accompanying drawings, Figure l is a central side sectional elevation of my improved spike-making machine, the same being constructed and arranged in accordance with my invention. Fig. 2 is a side elevation of the same, a portion of the frame of which is broken away. machine. Fig. 4 is an end View of a portion of the machine, showing the separator-frame and the side grip. Fig. 5 is an end view of the kicker or device for knocking out the finished spike from its position between the gripping-dies. Fig. 6 is a detailed view of a portion of the feeding mechanism, the outer plate of the supporting-frame 4being removed in order to better show the pawl and ratchet.

To construct a machine for making railway and other large spikes in accordance with my inventiom'l provide a frame l, of a suitable size and form of construction, and mount therein a drive-shaft 2, having a fly-wheel 3 and connected to a means for giving the said shaft a rotatable movement. Formed upon this drive-shaft 2 is a cam 6, adapted to operate a clamping -lever 4, the same being mounted upon a shaft 5 in bearings 9 and provided With the ordinary means or adjustmentplates lO, arranged at each end of the shaft, and with springs l1' to relieve the lever 4 should a double spike" enter between the clamping-dies. Arranged in the forward end of the lever 4 is a removable clamping-die 7, which, in connection with a stationary die 12 and moving die 8, will hold the spike 28 while the same is being headed This moving die 8 is mounted ,upon a shaft 13, arranged Fig. 3 is a plan view of the in bearings at the base of the frame l, and the said die formed with an outwardly-projecting portion 14, which extends la short distance beyond the side of the frame. Pivoted to a shaft 17 at one side of the frame 1 and operated by a cam 18, attached to the-driveshaft 2, is a lever 15, which is connected by a toggle-pin 16 to the( outwardly-extending arm 14 of the moving die 8 in a manner that willoperate'the said moving die 8 toward and away from the stationary die l2 to aid the die 7 in clamping the spike While forming the head of the same.

'The head of the spike is formed by the heading-die, which consists of a stout bar 20, capable of a limited forward movement in suitable guideways 2l by means of a cam 19 formed on the drive-shaft 2, and the said bar 2O being fitted with a headingdie 23 at its forward end and the die and bar recovered or brought back by a suitable spring 22, one

the one knife registering with the other and formed toshear through the bar 30, from which the spikes are formed, and at the same time press a chisel-point upon the same.

These disks 26 and 26' are mounted on shafts 43 and 43', the upper shaft of which is ar-l ranged in sliding bearings, which are held in position by set-screws 31. Each of these shafts 43 43'is fitted with a gear-wheel 38 38',

the one meshing with the other in order that the cutters may revolve in unison, and' connected to the upper shaft 43 is acrank 39, a ratchet 40, and spring-actuated pawl 41. This crank 39 is connected bymeans of a rod 37 to a crank 36, secured to a shaft 17', arranged across the frame. Attached to the other end of this last-mentioned shaft 17' is a slotted crank 30, in which a sliding block 32 is arranged, and the position of the said block regulated by means of a screw 33 in a manner that the said sliding block 32 may be IOO moved toward or away from the shaft 17' for the purpose of adjustment to regulate the throw of the crank 39, connected to shaft of the disks in which the cutters are mounted. This sliding block 32 is connected by a pitman 34 to the disk 18, forming a part of the cam for operating the lower clampinglever 15. The object of this last-described mechanism is to rotate the disks 26 and 26 a limited distance at each revolution of the drive-shaft 2, the said distance being regulated by the position of the sliding block. This movement of the disks feeds the bar 30 forward the length of one spike.

The knives 27 and 27 not being able to entirely shear or separate the bar 30 will leave a thin web joining the said bar with the spike 28, as shown in Fig. 1 of the drawings. Therefore it is necessary to provide a means for separating the two. This means consists of two bars 54, arranged in bearings or slides 46, the ends of which bear against the oscillating frame 25 and against small cams 55, formed in the drive-shaft 2 in a manner that at each revolution of the said shaft the bars will move forward, pushing the oscillating frame 25 and tearing or separating the spike from the bar. The oscillating frame 25 is recovered or brought back to position by a spring 60. (See Fig. 2 of the drawings.)

To knock the finished spike 28 from between the gripping-dies, a rod or bar is arranged in bearings at one side of the frame 1, the said rod 45 having a portion 47 bent at an angle adapted to contact with a projection 44 on the flywheel of the machine and the other end 47 bent inwardly to a position over the spike 28.

. At each revolution of the fly-wheel the end 47 of the bar 45 is moved upward, thereby moving the inner end 47 down, moving the spike free of the gripping-dies and permitting the same to fall beneath the machine.

In operation the bar 30, from which the spikes are to be formed, is fed between the disks 26 26', the said disks being rotated a distance corresponding with the length of the spike by means of the connected mechanism with the drive-shaft 2. This motion is derived from the disk 18, connected to the adjusting-crank 30, and by means of its shaft 17 motion is given to the crank 36 on the opposite side of the machine and from this crank 36 by the connecting-bar 37 to the crank 39, giving the same a back-and-forward or oscillating movement. This movement of the last-mentioned crank 39, together with the pawl 41 and ratchet-wheel 40, moves the bar 30 a predetermined distance into the machine and at the same time the cutters 27 and 27', operating to form the point of the said spike. The bar 30, not being entirely separated from the piece 29, will shove the same forward upon the next action of the ratchet-wheel 40, placing the said piece between the grippingies 8 and 12. These dies 8 and 12, together the top die, will hold the blank 26 rmly,

while the heading-die 23 forms the head of the spike 28 by its forward movement. The spike now being formed, the cams 55 move the two bars 54 forward, slightly turning the oscillating frame 25 upon its shaft, thereby separating the finished spike 28 from the blank 29 following. At this time the gripping-dies 8, 12, and 7 open and the kicker 47 operates to throw the spike free from the gripper-dies.

Various slight modifications and changes may be made in the details of construction without departing from the spirit of the invention. Therefore I do not confine myself to the exact construction shown and described.
