I, JOHN FLAVIL KINGSLEY of Athens in the county of Bradford and State of
Pennsylvania one of the United States of America foreman do hereby declare the
nature of this invention to be as follows:-
This may invention has relation to the means for making eye-bars; and it consists
in a die of peculiar construction, and also a frame provided with rollers upon which
bears the former head or other agency used for bringing the desired pressure upon
the upper die-section, as will be hereinafter described.
In carrying out my invention I employ a lower-die-section, which is triangular in
cross-section and cut away at its apex at one end thereof. The said section is
rigidly supported upon any suitable base, and is provided on each side of its inclined
faces, near one end of the same, with a projection.
The upper inner portion of the projection is cut away so that the space between
the adjacent edges of the two projections on the die-section, is formed substantially
parallel a portion of its distance, and then gradually widens or flares in a direction
toward the inner ends of the projections.
The upper section of this die, which is recessed upon its under side to coincide
with the angular face of the lower section, and which is provided at one end with a
projection, adapted to coact with the cut away portion of the lower die-section, thus
forming an opening corresponding in cross-section with the shank of the eye-har,
which is to pass therethrough.
The tapering-shaped blocks, which are secured on the recessed face of the section,
at one end thereof, and are so located that when the die-sections occupy proper
relative positions the blocks will abut against the outer edges of the projections, and
prevent said section from being moved from beneath the section.
A projection which is located on the recessed face of the section, at the outer end
thereof, and is so disposed that the vertex of the recess will extend on both sides of
the recessed portion of the die-section. The inner portion of the projection is cut
away to present a curved seat at which the extreme end of the eye-bar is to be
formed.
A frame, located on the upper face of the die-section is provided with a series of

page_text: transverse rollers, upon which bears the former-head, or other agency that is to effect
the operation of the die.
In practice the end of the bar, as it comes from the rolls with parallel sides and
edges, is heated and laid upon the lower section, with its shank portion extending
between the projections. Power is then exerted to cause the upper section, to move
longitudinally into position upon the lower section, the pressure exerted by the
roller frame and former-head causing the metal at the end portion of the flat bar to
be forced into angular wings, so as to lap the angular edge of the section, the
extremity of the eye-blank being also forced into said recessed portions, so that it
will become properly rounded. This angular bend in the bar is for the purpose of
holding it straight during the process of upsetting, and as soon as the die is closed
force is applied at the end of the upper section.
The space between the upper and lower die-sections enlarges somewhat in the
direction of the sides to effect an increased thickening of the head at its turned-down
portions. By this means it is not necessary to upset so much of the head, and
consequently when the head portion is drawn or flattened down to the thickness
desired it will be proportionately widened to form the shaped head desired.
When the heated bar is placed in the sections, and the latter moved longitudinally by
force, the roller-frame insures a greater reduction in the friction.
It will be understood that the movement of the section also effects a drawing as
well as a shaping action, thereby preventing any irregularity in the body of the
metal.
The several projections on the inside of the die-sections may be made movable and
of different thicknesses of bars to be operated upon.

page_text: Improved Die and Connection for Making Eye-bars.
I, JOHN FLAVIL KINGSLEY, of Athens, in the county of Bradford, and State of
Pennsylvania, one of the United States of America, Gentleman, 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 certain new and useful Improvements in Dies and
Connections for Making Eye-Bars; and I now proceed to describe the same, reference
being had to the annexed drawings, making a part of this specification, and to the
letters and figures of reference marked thereon.
Fig. 1 of the drawings is a perspective view of the upper die section and its
attachments; Fig. 2, a similar view of the lower die-section; Fig. 3, a longitudinal
central section of Fig. 4, taken on line xa; Fig. 4, a transverse section takon
on line y of Fig. 3 Fig. 5, a perspective view in detail of so much of an
eye-bar as is operated upon by my improved die; and Fig. 6 a similar view of a
like portion of an eye-bar, the same being represented as finished and ready to be
perforated.
The present invention has relation to dies for the manufacture of eye-bars, the
object thereof is to provide such a die with attachments that will materially facilitato
the production of the eye-bar and enable them to be more perfectly and successfully
formed; and it consists in forming the faces of the die-sections of different angles, and
also constructing the lower one of said sections with a recess at one end, and
providing the dic upon each side of the recess with plates.
It further consists in providing the roller-frame with dovetail grooves upon its
inner sides, to engage with similar-formed tongues on the sides of the upper die-
section, and also the platen.
The invention also consists in providing the upper die-section, and also the platen,
with central grooves, and providing the rollers with enlarged portions to fit therein to
form a guide for holding the parts together and prevent them from lateral
displacement, as will be hereinafter described and claimed.
In the accompanying drawings, A represents the lower die-section, which is
triangular in cross-section upon its upper side, where the eye of the bar is formed,
but made flat at one end, or, in other words, formed with a recess, as shown at a,
said die-section being supported by the base or bed of the machine, as shown in
Figs. 3 and 4.
The die-section A is provided at its recessed end with seats, to which are
detachably connected plates B; or, in other words, the die-section is formed with
flanges b at its sides and ends, against which abut the edges of the plates above
referred to, to hold them in place, said plates having their inner edges so shaped as

page_text: to conform to that portion of the head of the eye-bar desired or to the thickness
thereof. The upper and movable die-section, C, upon its under side is triangular in
cross-section, but of a sharper angle than the lower die-section, A, so that when
closed the space between the two enlarges from the centre toward the side. The end
of the die C is cut away to form recesses to receive the bifurcated end d of the
rammer D. The rammer D, upon its under side, is of such shape as to fit the
triangular shape of the lower die-section, A, and the bifurcated end of the rammer,
above described, is of such shape as to form the end of the upset portion of the bar
when acted upon, and in operation this rammer is connected to the piston-rod of the
machine.
Above the upper die-section, C, is a frame, E, the inner sides thereof having
dovetailed grooves e to fit correspondingly-formed tongues upon the outer side of the
die-section C, and a platen, F, as more clearly shown in Fig. 4 said platen forming a
part of or being fastened to the die-closer of the machine, which closer is of such
common construction and well known that it is not deemed necessary to show in the
drawings.
To the sides of the frame E are journalled the anti-friction rollers G, upon which
bear the platen and upper die-section, said rollers having an enlarged bearing, f
midway of its end, which fits in grooves g h in the lower die-section and platen,
respectively, thereby forming a guide for the two when moving longitudinally, and
the dovetailed grooves in the roller-frame, in connection with the correspondingly-
formed tongues, provide further means for guiding the lower die-section and platen
to prevent them from lateral displacement. The enlarged portion of the anti-friction
rollers, herein before referred to, performs a further office in that it keeps the upper
die-section in a central position when it is raised or lowered.
In practice, the end of the bar (as it comes from the rollers with parallel sides and
edges) is heated and laid upon the lower dic-section, A, between the plates B. The
upper die-section, C, is now forced down upon it to bend the bar longitudinally to
conform to the angular space between the inner faces of the die-sections or the space
between the same, and the bar is held from receding, the end thereof bearing against
the bifurcated end of the rammer D when in position, as shown in Fig. 3. Power is
now applied to the rammer, causing the upper die-section to move longitudinally
over the lower die-section, thereby forcing the end of the bar to assume the shape as
represented in Fig. 5, the rollers reducing the friction between the upper die-section
and platen when they are being moved. This angular bending of the bar is for the
purpose of keeping it straight during the process of upsetting. The enlarging-space
between the die-sections, by forming the upper one thereof at a sharper angle, as
hereinbefore described, permits the metal to be more freely forced outward to form
the head, and at the same time holding the centre so that no metal will be forced
from one side to the other.
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
1. The combination of an upper and a lower die-section triangular in cross-section,
as shown, the lower one of said sections having a recess at one end and the upper
one of said sections having a greater or sharper angle than that of the lower section,
whereby the space between the die-sections when closed will increase or enlarge
from its centre toward the sides thereof, substantially as and for the purpose
set forth.
2. The combination of an upper and a lower die-section having their faces or
meeting sides of different angles, and the lower one of said sections having a recess at
one end, and plates, of the form substantially as described and shown, arranged upon
each side thereof, for the purpose specified.
3. The combination, with a lower die-section triangular in cross-section, and an
upper dic-section, also triangular in section, and a platen arranged above it, of a
frame provided with rollers and having dovetailed grooves upon its inner side to

page_text: engage with similarly-formed tongues on the sides of the upper die-section and
platen, substantially as and for the purpose set forth.
4. The combination, with a lower die-section and the upper dic-section and
platen having central grooves upon their inner sides, of the roller-frame and rollers
having enlarged portions to fit in the grooves of the upper die-section and platen,
substantially as and for the purpose set forth.
5. The combination, with the lower die-section and upper dic-section, having at
one end recesses, as shown, of a rammer having a bifurcated end adapted to engage
therewith, whereby said upper die-section is operated, substantially as and for the
purpose specified.
