page_text: I, GEORGE BARR, of 5950, Princeton Avenue, in the City of Chicago, in the
County of Cook, in the State of Illinois, one of the United States of America,
Mechanic, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in spike-machines consisting of a
machine for making and discharging spikes, which are chiefly adapted for railway
purposes.
The important feature of the machine being to make a perfect-shaped spike
by means of heading and pointing dies in such a manner that there can be no
possibility of said spikes remaining in the dies or in such near vicinity as to
clog the machine.
The object of the machine being to make a perfect-shaped spike, to release
the spike from the dies and to discharge the same quickly, and in such a manner
that the dies are cleared and no possible interference can be presented either
to the next spike-blank, or to the action of the dies.
This is accomplished by means of revolving feed rollers secured on the
extended ends of short shafts suitably journalled in a supporting frame, two
intermittantly revolving discs or pointing dies each of which is provided with a
circumferential flange projecting from one edge thereof in such a manner that
the flange of one disc laps past and engages with the unguarded edge of the
other. The metal billet, or blank, is fed between these two discs which at
corresponding points on their peripheries are provided with inset-dies shaped to
point the rear end of the spike blank which has passed between the discs and
sever it from that which follows:
The heading die, and the gripping die, and the spike discharging bars, are
operated from the drive shaft by connecting rods and levers. After the spike-
blank has been severed from the billet by the cutting dies, it passes between
two continuously revolving rollers, on to the female die, and is stopped by a
stop gage, retaining the spike-blank in its place, after which the gripping
die falls on the spike-blank, which is held rigid between the female die and
the gripping die, then the heading die comes in contact with the end of the spike-
blank and forms the head which finishes the spike, the stop gage moves out
of the way for the heading die to do its work.
The gripping die is then released from the finished spike, and a lifting rod
comes through the floor of the female die and lifts the head end of the spike,
after which the discharging bars, pushes the spike away from the female die.

I, GEORGE BARR, of 5950, Princeton Avenue, in the City of Chicago, in the
County of Cook, in the State of Illinois, one of the United States of America,
Mechanic, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention relates to improvements in spike making machines consisting of
a machine for making and discharging spikes, which are chiefly adapted for
railway purposes. The important feature of the machine being to make a perfect-
shaped spike by means of heading and pointing dies in such a manner that there
can be no possibility of said spikes remaining in the dies or in such near vicinity
as to clog the machine.
The object of the machine being to make a perfect-shaped spike, to release
the spike from the dies and to discharge the same quickly, and in such a manner
that the dies are cleared and no possible interference can be presented either
to the next spike-blank, or to the action of the dies.
on the
This is accomplished by means of revolving feed rollers secured
extended ends of short shafts suitably journalled in a supporting frame, two
intermittantly revolving discs or pointing dies each of which is provided with a
circumferential flange projecting from one edge thereof in such a manner that
the flange of one disc laps past and engages with the unguarded edge of the
other. The metal billet, or blank, is fed between these two discs which at
corresponding points on their peripheries are provided with inset-dies shaped to
point the rear end of the spike blank which has passed between the discs and
sever it from that which follows:-
The heading die, and the gripping die, and the spike discharging bars, are
operated from the drive shaft by connecting rods and levers. After the spike-
blank has been severed from the billet by the cutting dies, it passes between
two continuously revolving rollers, on to the female die, and is stopped by a
stop guage, retaining the spike-blank in its place, after which the gripping
die falls on the spike-blank, which is held rigid between the female die and
the gripping die, then the heading die comes in contact with the end of the spike-
blank and forms the head which finishes the spike, the stop guage moves out
of the way for the heading die to do its work."
The heading die and the gripping die is then released from the finished spike,
and a lifting rod comes through the floor of the female die and lifts the head end
of the spike, after which the discharging bars, pushes the spike away from the
female die.
The nature of this invention is more fully disclosed by reference to the accom-
panying drawings in which :-
Figure 1, is a plan of the spike making machine embodying my invention.
Figure 2, is an enlarged side elevation of the spike forming mechanism.
Figure 3, is a side elevation of the machine showing the spike forming
mechanism, the driving pulley and other parts of the machine being removed in
order to show more fully the invention.
Figure 4, is a detailed view of the gripping lever, the rounded ends of which
swivel in trunions, the gripping die being secured in said lever.
Figure 5, is an enlarged side elevation of the pawl and ratchet wheel which
operates the cutting dies.
In the drawing A represents two intermittently revolving disks, inserted in
these disks are four cutting dies, a, in each, so arranged that the points meet,
these disks revolve a quarter of a revolution, drawing the billet forward, these

page_text: cutting dies always meeting at every quarter of a revolution and are so shaped that
they point the rear end of the spike-blank which has passed between the disks,
and sever it from that which follows:-
When the spike-blank has been severed by the cutting dies, a, from the
billet, it passes between two continuously revolving feed rollers B, which bring
the spike-blank on to a female die C, and is stopped by a stop-guage D. The
spike-blank which rests in groove b, is then gripped by a gripping die E, which
holds the said blank in position for a head to be formed on it by means of a
forming and heading die F, which strikes the end of the spike-blank at an
angle, pressing part of the metal of the said blank into a depression 3, which
is countersunk as shown on the drawing at the end of the groove b, and necessary
to form the head of the spike, when this is done the spike is ready for use.
After the spike-blank has been formed into a perfect spike the gripping die E,
and the heading die F, release the said spike, said gripping die moving vertically
and the heading die moving upwards on an angle.
In order to render effective the operation of the mechanism, used to discharge
the spike, the upper surface J, of the female die C, is inclined on each side of the
groove b, toward the rollers B, or on the side over which the spike is discharged
and is rounded at the side so that when the spike is once pushed out of the
groove b, does not find lodgment on said surface. After the spike has been
headed, a lifting rod H, comes through the floor of groove b, and lifts the head
end of the spike, after which two push bars K, push the spike over the surface J,
from thence it falls through the bed of the machine and onto the ground, the push
bar that pushes the pointed end of the spike is lower than the one that pushes the
head end of the spike and do coincide to the inclined surface of the female die.
One of the push bars K, may be used by putting it near to the centre of the
spike.
The disks A, are secured on parallel shafts L, that are geared together by corre-
sponding spur wheels M, one of said shafts has a ratchet wheel N, on its end,
which is engaged by a pawl O. The pawl O, is actuated from the drive-shaft W,
through the medium of a crank P, and a connecting rod R, in such a manner
that with each engagement thereof the shafts L, simultaneously move a quarter
of a revolution. The cross bars 45, and 46, at the ends of the shafts L, and L,
and the screw stops 47, at the opposite end of said shafts to prevent the same from
moving laterally, in order to produce perfect and well defined spikes.
The feed rollers B, are secured on short shafts S, which are geared together
by corresponding spur wheels T, and a miter-wheel U, at the opposite end of said
rollers is secured to the end of the lower shaft T, and is geared into a miter-
wheel 5, which is secured on the end of shaft V, and at the other end of said
shaft V, a pinion 2, is geared into a bevel-wheel 4, which is secured to the drive
shaft W
The gripping die E, is secured at 6, to the gripping lever 8, which swivels on
trunions 10, by means of a cam 12, which is secured on the drive shaft W. A
tension spring 14, is secured to the gripping lever and the bed of the machine,
and the spring binds the lever to the cam, which gives the lever its motion, and
vertically reciprocates the gripping die.
The forming and heading die F, is secured to a carrier 16, and reciprocates
on an angle, a crank 18, on the drive shaft W, gives the carrier its motion by
connecting rod 20.
The lifting rod H, reciprocates vertically by means of a lever 22, on the end
of the rock-shaft 24. Secured at the other end of this rock-shaft, is a lever 26,
which receives its motion from a crank 27, on the drive-shaft W, and rocks the
said shaft by means of the connecting rod 28. The push bars K, are secured
to swivel pins 30, on the end of lever 32, which gives the said bars their motion.
On the drive-shaft W, the cam 34, secured thereto operates the lever 32, by means
of the small roller 33, which runs in the groove of the cam, this lever 32, is
pivoted at 39.

page_text: The stop-guage D, operates in the same manner as the push-bars, and is
pivotted at the end of lever 36, which swivels on the pin 38, giving the stop-
guage its motion, small roller 37, secured at the other end of the lever 36,
operates in a grooved cam 40, on the drive shaft and rocks said lever which is
pivotted at 38. This drive-shaft W, provided with a drive pulley 44, revolves
on bearings 42, and drives all the operating mechanism.
Various changes in the form, size and proportion of the component parts of this
invention may be resorted to without departing from the spirit and scope thereof.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. A spike-making machine, comprising intermittantly revolving cutting
dies continuously revolving feed rollers, a stationary female die having groove
