SAMUEL E. DRAKE, OF CANTON, ILLINOIS, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO WILLIAM PARLIN AND.WIL LIAM J. ORENDORFF, OF SAME PLACE. v
IMPROVEMENT IN DIES FOR BENDING CULTlVATOR-BEAMS.
Specification forming part of Letters Patent No. 178,744, dated June 13, 1876; application led May 17, 1816.
of Illinois, have invented an Improvement in- Dies for Bending Oultivator-Beams; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this speciticatiomin which like letters of reference refer to like parts, and in which- Figure 1 represents a perspective View of the main die; Fig. 2, perspective view of the upper die-z'. e., the inner face 5 Fig. 3, vertical section of latter die on line a a, Fig. 2; Fig. 4, section of main die on line b b, Fig. l; Fig. 5, plan view of cultivator-beam, showing the lateral twist.
The object of this device is to confer the bend and the necessary twist to the beam of a cultivator at one and the same time, meaning the lateral curvature (twist) necessary to bring the end which receives the. plow parallel with its neighbor 5 and consists, rst, of a main die with a detent for holding a straight bar for the bending process; second, a gage for limiting the length ofthe leg, or that part vvof the beam which is to receive the shovel,
and allowing the same to be inserted only to the proper distance; third, the upper die.
The main die is a vertical block of iron provided with a shoulderu conforming to the straight portion of a cultivator-beam for part of its length, diverted into a curve downward, upon which the heated bar is pressed by the upper die. The face of the die is also formed to give the necessary side twist to the bar, above described. To admit into the dies only so much of the bar as will produce the necessary length of the curved end, a gage is attached to the back face of the main die in a line with said straight part of the shoulder, in such wise as not to interfere with the action of the other die. A clamp, cam, lever, or other detent is attached above and ne`ar the outer end of said shoulder, to hold the bar during its formation into a beam. The kother die has a recess or die-surface conforming to the shoulder ofthe rstdescribed die, and to the face said beam receives its curvature. Athe inner or lower end of the curved part of of the same, and to which it is confined in its action when struck or pressed by a guide on the outside, which bridges the inner end of the recess on the main die, or by any effective device for keeping the dies during pressure in close contact. Of course reverse dies will be necessary to form the corresponding beam. The dies may be operated by an ordinary drophammer or by any other effective machine.
In the drawings, which represent one of the forms in which I construct the dies, A represents the main die, having a shoulder or table, a a, of slight elevation-z'. e., the thickness of thebeam-connected with the surface of the die by sides which join the latter (surface of die) at a right angle, and upon which Opposite the shoulder a is a second shoulder or incline designed to force the upper die B against the bar E, to make the latter conform to a a a. Above the straight part of said table a is stationed a cam-headed lever, D, having an outer iiange beyond the bar E to retain the latter when the force is applied. In a line with the same straight portion of said table ais a gage or stop, d, having a shoulder, m, to limit the undue insertion of the bar or beam within the dies. The main die A has a hase, t', or widening of its lower side, `and nearit, spanning the hollow betwee'n the table a and the incline k, is a guide, e, to keep the dies in contact under pressure.- B is the upper or striking die, which, on its inner surface, conforms exactly to its fellow A, being provided with a similarshoulder or table, but incurved or hollow, so as to be parallel with a a, but leaving space between for the substance of Ythe beam E. This die need be of no great thickness, as its depth makes up any deiciency in this direction 5 but it is widened at its top h, and projects above the main die at all times the better to receive force or pressure from the hammer, Ste. The face of each die at that party which compresses the lower end of the curve of the beam has a warp or incline, 2 2", or descent of their respective surfaces in a direction away fromthe respective shoulders a ag g, which give the `necessary side twist to the beam E, that the attached shovels may be parallel with each other.
What I claim as my invention is 1. The main die A audits reverseprovided with the curved table a a, a detent for th'ejnsexted beam above the table, the gage d, the incline k, facing the eurved part of said table, with guide e, and the striking-die B, for the prpose of conferring on a eultivator-beam at once the proper curve, and also the lateral twist, substantially as described.
2. The die A and its reverse, combining-the In testimony that I claim the foregoing Dies for Bending Gultivator-Beams I have hereunto set my hand this 5th day of May,-A.
