CHARLES O. VILDER, OF SOUTH BEND, INDIANA, ASSIGNOR TO WILLIAMS, WHITE St CO., OF MOLINE, ILLINOIS.
MACHINE FOR FORMING EYES ON RODS.
SPECIFICATIN 'forming part of Letters Patent No. 383,084, dated May 15, 188%. Application filed September 12,1887. Serial No. 249,468, (No model.)
To all whom it may concern:
Be it known that I, CHARLES O. Winona, a citizen of the United States, residing at South Bend, inthe county of St. Joseph and State of Indiana, have invented a new and useful Improvement in Machines for Forming Eyes ton Rods, of which the following is a specificaion.
My invention relates to an improved machine for forming eyes on rods, as in car-coup ling pins, eyebolts, and like devices.
The object of my improvement is to form an eye on the end of a rod by means of a machine having a reciprocating head arranged to move on a fixed bedframe, and suitable dies secured to said bed-frame and reciprocating head, the dies being so formed and arranged that a complete eye may be formed at each movement of the reciprocating head, all as hereinafter fully described.
The accompanying drawings illustrate my invention.
Figure l is a plan showing the position of the parts when the first bend has been made. Fig. 2 is a similar pian showing the position of the parts when the second bend has been made. Fig. 3 is a similar plan, showing the position oftheparts when the eye is completed. Figs. 4L, 5, and 6 are views, on an enlarged scale,of the dies ,when in the position shown in Flgs. l, 2, and 3, respectively. Fig. 7 is a perspective view of one of the dies. Fig. 8 is a vertical section at a, Fig. l.
My improvement is adapted to be used on any of that well-known class of machines having a bed-frame to which the main portion of the dies may be secured, and a reciprocating head, to which the remainder of the operating parts may be secured. As such machines are well known, I do not here illustrate the inachine in full, but only such parts as are neces sary to illustrate my improvement.
A is the bed-frame, on which the crosshead B is reciprocated by means ofthe connecting rods O C, which are attached to suitable driving mechanism (Not shown.)
D is a heavy castiron plate having a pair of swingingjaws, E F, pivoted thereto at dal, the plate being rigidly secured to the bed- 50 frame by bolts e e. Jaw E is provided with a vertically therein. Pin his raised and lowered by means of the lever 7c, which is pivoted to the pin and to a standard, Z, erected on bar J.
K is a straight-edged block projecting upward from the surface of plate D, and arranged to support one side of the rod m, on which the eye is turned.
L is a die having a projecting portion, u, Fig. 7, in which is a transverse mortise, o, and having also a solid portion, p, in which is a notch, r, corresponding to one-fourth of the exterior circumference of the eye to be formed.. Die L is rigidly secured to the reciprocating cross-head B and is arrranged to slide in a groove, s, in the surface of plate D.
M and N are projecting studs secured to the crosshead B and arranged to slide against the inner opposed surfaces of the guide-bars H and I. The ends of studs M and N are provided with oppositely-inclined surfaces,t and u.
The operation is as follows: The cross-head B being drawn back to the full extent of its movement and the jaw E being open, the straight bar m is placed between the jaw E and the pin l1, the end of the bar projecting beyoud the pin sufficient] y to form three-fourths of the eye. As the cross-head B moves for.- Ward, carrying the studs M and N and the die L, the inclined face t of the stud M first comes in contact with jaw E and passes between the jaw and the guide-bar H, thus forcing the jaw against the rod m and bendingit partlyaround the pin, as seen in Figs. l and 4;. The end of the projecting portion a of die L now comes in contact with the rod, bending the rod as the die moves forward farther around the pin, as seen in Figs. 2 and 5. The inclined face c of the stud N then comes in contact with the jaw F, and, passing between thejaw and guide-bar I, forces thejaw through the mortise o in die Ioo the same time the operator raises the pin h by means of the lever 7c, thus withdrawing the pin from the eye and releasing the rod.
I claim as my invention* -Io I. In an eye-forming machine, the fixed plate D, having guide-bars lITI and I, jaws E and F pivoted to said plate, pin h, mounted in fixed bearings between thejaws, the reciprocating cross head B, die L, secured to said reciprocating head, stud M, having inclined face 15 t, and stud N, having inclined face u, said studs being also secured to the reciprocating head,
all being arranged to co-operate, substantial] y as and for the purpose specied.
2. In an eye-forming machine, the die L, 20 having the projecting portion n, niortise 0, solid portion p, and notch 1'.
