- MACHINE FOR SHAPING .ME'TAL BY ROLLS.

SPECIFICATION forming part of Letters Patent N6. 627,546, dated. June 27,1899.

Application filed March 1 6, l 8 9 9 To all whom zit may concern.-

Be it known that I, JOHN TEDELL, a citizen of the United States, residing at Moline, in. the county of Rock Island and State of Illinois, have invented certain new and useful Improvementsin Machines for Shaping Metal by Rolls; and I do hereby declare the follow;

ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for shaping metal parts by rolls operating to upset portions of the blank and forge the same to conform with a recessed die, the particular of which is illustrated inthe accompanying drawings, forming part of this specification.

Figure I represents the machine, partly in side elevation and partly in section, with the parts in the relative positions obtaining normally or when a blank is first introduced.

Fig. II is a similar View of a portion of the machine with the relation of parts changed, as when the rolls have operated on the blank and upset portions of the same. Figs. III and IV show sections on different lines of portions of the rolls and the forged blank, the scale being considerably enlarged as compared with Figs. I and 11. Fig. V represents the machine in front elevation. Fig. VI shows the dieclamping mechanism in rear elevation, together with the lower roll.. Fig. VII represents the die in perspective. Fig. VIII represents the blankin perspective, and Fig. IX represents the finished product in perspective.

The framework of the machine comprises side standards a of bifurcated form, which are erected upon a suitable bed-plate, as that of a type of machine forgiving reciprocatory motion commonly known as a bulldozer,

the cross head or slide of the same being designated by the letterb. The bifurcations of the said standards are occupied by two pairs of journal-boxes c and d, one pair resting against the bottoms of the bifurcations and the other pair resting upon heavy spiral springs e,bearing on the lower pair of journalboxes. The frame is completed by a cap f,

which is securely bolted to the side standards,

and screws 9 passithrough bosses provided for them in this'cap-piece, said screws bearing against the upper pair of journal-boxes and being equipped at their upper ends with hand-wheels 9, whereby the upper pair of journal-boxes are adjusted again st the tension of the springs. These upper journal-boxes support a roll h, circular in cross-section and having an exterior surface which is convex from end to end. The lower journal-boxes support a roll 2', which is partiallycircular in cross-section and has a face which is concave from end to end, conforming with the convex-' ity of the roll h, whose convex surface is in close contact with the concave surface of the lower roll. The latter has formed integrally with it anarm 'i, the lower end of which is coupled with the cross-head b by a link j, so-

that reciprocations of said cross-head will produce oscillations of the concave roll to such an extent as to bring the major portion of the face of the latter into contact with the upper roll. The lower roll is made with a movable section 7t,- which constitutes a die, said section slidingly engaging a cut-out portion of the roll and being concavedinits outer side in conformity with the balance of the face of the roll.

The machine here shown is designed to operate upon a blank for a plow-land'side, and the die is is made with a shallow recess in (see Fig. VII) in its in nerface','of triangular outline, the two edges of the blank not acted on by the rolls being adapted to engage the sides of thisrecess which are substantially at right angles to the inner face of the die-block. This recess opens out of the concave face of the block, and the latter is cut out slightly for a considerable distance from the short side of the recess, as shown at 10 forming a groove which widens as it approaches the" opposite end of the block, as shown at 70 the lower side of the recess 70 merging into the bottom of the widened portion of said groove, as shown at k.

The landside-blank is shown in Fig. VIII and designated by the letter m, and it will be observed that the same is generally triangular in outline, one side, however, having a double curve, giving it a bulge near the narrow end of the blank, as shown at m. As before stated, this blank occupies the recess is, and when its two straight sides engage the sides of said recess the curved side stands slightly above the concave face of the dieblock, so as to provide sufficient metal to be rolled down into the groove 70 the bulge m of the blank providing sufiicient metal to fill the widened portion k of the said groove, so

- that when the rolls have operated on the v relation.

blank it will be caused to completely fill the die-recesses and partake of the shape of the same. 7

Fig. IX represents the product of the machine, and it will be observed that the curved side of the blank is rolled down, so as to provide a bead m extending along the greater portion of its length, and that the bulge m of the blank is rolled down into a thin fiat blade on. A die-plate n (see Figs. III and IV) is let into the surface of the roll '11 opposite the recess in the die-block, and the blank is clamped between this die-plate and said block by the following-described mechanism. A draw-bolt 0 is fitted to slide through an opening in the roll and engages a registering opening in the die-block, the latter opening, however, being of somewhat less diameter than that in the roll-body and the bolt being shouldered at 0' to bear against the inner face of said block and screw-threaded on its end which projects from the block, so that a nut 0 applied to said screw-threaded end,may secure the block to the boltin a fixed A lever 0 is pivoted at its upper end to lugs 0 formed upon the rear side of the roll 1', and said lever is jointed at 0 to the bolt 0 and at its lower end is formed with a longitudinal slot 0 This slot is engaged by a pin 0 fastened in the outer end portion of a bifurcated arm 1), which extends on opposite sides of the lever 0 and is fastened to a stud p, journaled in the arm 6. A tumbler-plate p is also fastened to said stud and extends at an angle to the arm 1), said tumbler-plate being of oblong form and bifurcated at its outer end, as shown at 19 A stud or pin p is fastened in one of the standards a, of the frame and projects from the inner side there of for engagement with the bifurcation of the tumbler-plate, said bifurcation being of a flaring form, so as to enable its sides to readily engage the said pin or stud.

The normal position of the parts is illustrated in Fig. I, and it will be observed that the lever o lies in close proximity to the rear side of the arm 2', and the tumbler-plate is for the most part in rear of the pin 1%. Upon the forward movement of the arm 1' the upper side of the bifurcation of the tumbler, riding against the pin 19 causes the said tumbler to turn on its pivot, which results in a corresponding movement of the arm and pressure of the pin 0 against the upper side of the slot 0 whereby the lever o is forced outwardly or away from the arm 2", and consequently draws upon the bolt 0 and forces the die-block 7c inwardly. Before the tumbler leaves the pin 19 it has been turned to the position shown in Fig. II, where the pin 0 has passed the center or a radius of the stud p at right angles to the lever 0 causing the clamping mechanism to lock itself. Upon rearward movement of the arm i the tumbler again encounters the pin 1), so that it will be turned back to its original position, releasing the die-block from its clamping adjustment and permitting the removal of the landside. hen the arm i is driven forward, it will be seen that all portions of the blank projecting from the face of the concave roller will encounter the convex face of the upper roller and will be upset thereby into the form shown in Fig. IX, the surface of the beaded and flattened portions of the blank partaking of the curvature of the upper roll, as well illusstrated in Fig. IV. hen the arm t" is returned to its original position, this outer surface of the blank is again acted upon by the upper roller, so that a finishing action is had, and the landside issues in condition to be welded to the share.

It will be seen that by interchanging dieblocks the machine can be adapted to the production of various articles, and it is the intention to employ the machine for upsetting the edge of the share to adapt it for welding to the landside.

I have here shown a machine especially designed to operate upon blanks for plow parts; but it is to be understood that a great variety of otherarticles can be produced by a machine constructed in accordance with my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine of the character described, the combination of shaping-rolls with faces contacting under pressure one of said rolls having a movable section and a die-recess in its face, mechanism for oscillating the sectional roll, and automatic means operated by said mechanism for clamping the blank between the sections thereof under one direction of movement and releasing the same under the reverse direction of movement.
