DIE AND CONNECTION FOR MAKING EYE-BARS.

SPECIEICATION forming part of Letters Patent No. 357,833, dated February 15,1887.

Application filed October Q6, 1886. Serial Xo.17,200. (No model.)

To CLZZ whom itsmay concern.-

Be it known that I, JOHN F. KINGSLEY, a citizen of the United States, residing at Athens, in the county of Bradford and State of Penn sylvania, have invented certain new and useful Improvements in Dies for Making Eye- Bars; and I do hereby declare that the following is a full, clear, and exact description of 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.

The present invention has relation to the means for making eye-bars; and it consistsin 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 dissection, as will be' hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of the two sections composing the die used in the practice of my invention. Fig. 2 is atransverse section through said die sections, the latter being represented in operative position with respect to an eyebar. Fig. 3 is a longitudinal section through the die and the eye-bar, the relative positions represented in Fig. 2 being still preserved. Fig. 4 is a perspective view of so much of an eyebar as is operated upon by the improved die; and Fig. 5.is also a perspective view of a like portion of an eye-bar, the same being represented as finished and ready to be perforated.

In carrying out my invention I employ a lower die-section, A, which is triangular in cross-section and cut away at its apex at one end thereof, as represented at a in the lower portion of Fig. 1. The said section A 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, 12, which is of the form most distinctly seen in Fig. 1, and also represented in Fig. 3 by dotted lines.

It will be observed, by reference to Fig. 1, that the upper inner portion of the projection b is cut away, as represented at 0, so that the space between the adjacent edges of the two projections on the die-section A is formed subthen gradually widens or flares in adirection toward the inner ends of the projections.

B designates the upper section of the die, which is recessed upon its under side to coincide with the angular face of the lower section, A,and which isprovided at one end with a pro jection, d, adapted to coact with the cut-away portion a of the lower die-section, thus forming an opening corresponding in cross-section with the shank of the eye-bar, which is to pass therethrough.

0 0 refer to tapering-shaped blocks, which are secured on the recessed face of the section B, at one end thereof, as illustratedin Fig. 1, and are so located that when the die-sections occupy proper relative positions the blocks G -will' abut against the outer edges of the projections b and prevent said section A from being moved from beneath the section B in the direction indicated by the arrow shown in Fig. 1.

D refers to a projection which is locatedon the recessed face of the section B, 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 D is cutaway at e, to present a curved seat at which the extreme end of the eye-bar is to be formed.

A frame, E, located on the upper face of the die-section B, is provided with a series of transverse rollers, f, upon which bears the former-head F, 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 projeclions b. Power is then exerted to cause the upper section, B, to move longitudinally into position upon the lower section, A, 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 A, the extremity of the eye-blank be ing also forced into said recessed portions 6, 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 and it is forced edgewise to the dotted line a", Fig. 3.

It will be noted, by reference to Fig. 2, that the space between the upper and lower diesections 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 ofthe 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 A B and the latter moved longitudinally by force, the roller-frame insures a greater reduction in the friction.

It will also be understood that the movement of the section B also effects a drawing as well as a shaping action, thereby preventing any irregularity in the body of the metal.

When the bar is reiiioved from the diesections, it is of the shapercpresented in Fig. 4, at which time it is ready to be flattened out, as shown in Fig 5.

The several projections on the inside of the die-sections may be made movable and of different thicknesses for different thicknesses of bars to be operated upon.

Having now fully described my invention, what I claim as new, anddesire to secure by LettersPatent, is-- 1. The combination of an upper and lower die-section triangular in cross-section, as shown, and having projections upon their inner or meeting faces, the upper one of said diesections adapted to move longitudinally and edgewise on the lower die section.

2. The combination, With a lower die-section and a longitudinally-moving upper diesection, of a former-head and a frame provided with rollers supported upon the upper one of the die-sections, substantially as and for the purpose specified 8. The combination, withan upper and a lower diesection having projections, as described, of the roller-frame, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN F. KINGSLEY.
