- the object of my invention is to provide new and improved forms of sectional or adjustable drawing-dies for usein drawing metal rods or bars for the purpose of giving their surfaces an accurate form and finish or for increasing their strength and elastic limit or for successively reducing the section, as in wire-drawing.
- My invention has special reference to dies for drawing rectangular or square bars, rods, or wire, although it may also be adapted and applied for use in drawing other bars of regular or irregular polygonal or other section, as may be readily understood.
- My improved die consists of four die-blocks, preferably of pentagonal form, each block being formed with one of its edges convex or rounded to serve as a working face, while one of the edges adjoining said convex face is concaved in such a way as to fit the convex surface of the adjoining die-block.
- the principal flat surface of the dieblock which I prefer to use has the general appearance of a rectangle with two of its adjoining corners cut off in such'a way as to form a surface ending in a right angle, and although not strictly essential I prefer the form in which one corner is out off more than the other.
- the longer of the two angular edges of each die-block formed as above described is prefably made convex to serve as a working face,
- die-plate are accurately fitted,only, one wedge is necessary to complete the adjustment, as by means of this the movement of one block would determine the motion of all, as may be readily understood by inspection of the drawings.
- the old and present form of die-block for use in drawing square bars is made from a solid plate which is difficult to manufacture, as the work on the interior surface of the working face has to be done by hand, owing to the smallness and shape of the aperture, which does not permit of machine-work.
- said solid dies are difficult to repair or renew when they become worn, as any slight imperfection in their working surfaces is sufficient to destroy their usefulness.
- the working and other surfaces of my improved'form of sectional die-blocks are straight and accessible too in such a way that they can readily be trued up on agi-inding-machine or other suitable tool when worn by use.
- the wedges which I prefer to use may either be formed with single or double taper and provided with threaded bolt ends the nuts of which bear either directly or indirectly against the rear faces of the die-plate before mentioned.
- the wedges may be formed with bolts and nuts for adjusting and taking up the lost motion in my dieblocks, I do notlimit myself to this exact construction, as I may use Wedges without the bolts or set-screws working in threaded holes formed in the die-plate and bearing against the edges of my adjustable die-blocks, or, in
- any suitable means for adjusting and holding the die-blocks in a suitable position with relation to one another as may be readily understood.

- Said stop D is a wedge or stop fitting between one of the wedges D and one of the die-blocks A. Said stop D, acting in conjunction with the wedges D, serves to secure the die-blocks in position, the wedges D holding the die-blocks from moving in one direction, while the stop D prevents their motion in the opposite direction, as may be readily understood.

DIE FOR DRAWING METAL RODS.
SFECIFICATION forming part of Letters Patent No. 686,365, dated November 12, 1901.
Application filed December 6, 1899. Serial No. 739,398- (No model.)
To all whom it may concern:
Be it known that I, Guoaon E. THAOKRAY, a citizen of theUnited States,residingat Westmont, in the county of Oambria and State of Pennsylvania, have invented certain new and useful Improvements in Dies for Drawing Metal Rods and Bars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.
The object of my invention is to provide new and improved forms of sectional or adjustable drawing-dies for usein drawing metal rods or bars for the purpose of giving their surfaces an accurate form and finish or for increasing their strength and elastic limit or for successively reducing the section, as in wire-drawing.
My invention has special reference to dies for drawing rectangular or square bars, rods, or wire, although it may also be adapted and applied for use in drawing other bars of regular or irregular polygonal or other section, as may be readily understood.
Although my invention may be adapted for use in drawing rods or bars of various crosssections, as above described, in order to simplify my description I will refer herein only to that form which is adapted for use in drawing square or rectangular bars, the adaptation and arrangement for other sections than these being obvious. it
My improved die consists of four die-blocks, preferably of pentagonal form, each block being formed with one of its edges convex or rounded to serve as a working face, while one of the edges adjoining said convex face is concaved in such a way as to fit the convex surface of the adjoining die-block.
The principal flat surface of the dieblock which I prefer to use has the general appearance of a rectangle with two of its adjoining corners cut off in such'a way as to form a surface ending in a right angle, and although not strictly essential I prefer the form in which one corner is out off more than the other. The longer of the two angular edges of each die-block formed as above described is prefably made convex to serve as a working face,
clined faces at or near the corners to serve a as bearings for the adjusting-wedges, one wedge being provided to bear against each die-block and the adjoining surface of the dieplate for the purpose of adjusting the former within the latter.
If the surfaces of the die-blocks Where they bear against the surfaces of the recess in the.
die-plate are accurately fitted,only, one wedge is necessary to complete the adjustment, as by means of this the movement of one block would determine the motion of all, as may be readily understood by inspection of the drawings. In order, however, to avoid the necessity for the most accurate fitting, I prefer to provide, as above mentioned, one adjusting-wedge for each of the die-blocks, and in addition I also preferably provide other wedges which bear against the ends of two or more adjoining die-blocks in order to take up any lost motion caused by the loose fitting of the die-blocks Within the recess formed in the die-plate.
The old and present form of die-block for use in drawing square bars is made from a solid plate which is difficult to manufacture, as the work on the interior surface of the working face has to be done by hand, owing to the smallness and shape of the aperture, which does not permit of machine-work. In addition to this said solid dies are difficult to repair or renew when they become worn, as any slight imperfection in their working surfaces is sufficient to destroy their usefulness. On the other hand, the working and other surfaces of my improved'form of sectional die-blocks are straight and accessible too in such a way that they can readily be trued up on agi-inding-machine or other suitable tool when worn by use.
After my dies have been so worn as to be temporarily useless I can grind their surfaces easily, as above described. This grinding somewhat reduces the size of each block, which reduction, however, is provided for by the use of the adjusting-wedges aforesaid, which compensate for this change of size within reasonable limits, as may be readily understood.
The wedges which I prefer to use may either be formed with single or double taper and provided with threaded bolt ends the nuts of which bear either directly or indirectly against the rear faces of the die-plate before mentioned.
In order to provide ready means of alining the center of my dies, I prefer to make the die-plate and its holder in the form of a segmental ball and socket adjustable by means of set-screws in a hinged gate forming part of the head-block of a drawing-machine. Although I prefer to use a die-plate so formed as to be adjusted in the manner above described, I do not consider this part of my invention and do not claim it herein.
Although in certain cases the wedges may be formed with bolts and nuts for adjusting and taking up the lost motion in my dieblocks, I do notlimit myself to this exact construction, as I may use Wedges without the bolts or set-screws working in threaded holes formed in the die-plate and bearing against the edges of my adjustable die-blocks, or, in
fact, any suitable means for adjusting and holding the die-blocks in a suitable position with relation to one another, as may be readily understood.
Having given this general description of my invention, I will now refer to the annexed three sheets of drawings, which form part of this specification, and in which like letters refer to like parts.
Figure 1 is a general front elevation showing my die-blocks in position within the dieplate, all being contained in the head-block of a drawing-machine preferably provided with a hinged gate and means for adjusting the alinement of the dies. Fig. 2 is a central cross-section through the die-plates, blocks, and head on line 2 2 of Fig. 1. Fig. 3 is a front elevation of my die-blocks contained within a die-plate similar to the View of these parts shown in Fig. 1, with head-block removed, but showing the same dies adjusted to produce a bar of smaller section. Fig. 4is a front elevation showing an arrangement of dies to produce a rectangular section. Fig. 5 is a front elevation of a modified arrangement of my die-blocks and die-plate, each die-block in this case being provided with an adjustable wedge at one side and another wedge at the end, the latter serving to take up the lost motion and preserve the central position of the draw-hole. Fig. 6 is a crosssection taken on the line 6 6 ofFig. 5. Fig. 7 is an arrangement of my die-block in which but one side wedge and four end wedges are used. Fig. 8 is an arrangement of my die-block in which plain side wedges are used for adjustment of the blocks, together with a stop-block or wedge. Fig. 9 is a cross-section taken on line 9 9 of Fig. 8. Fig 10 is an arrangement of my die-block in which set-screws are used for the adjustment of the blocks. Fig. 11 is a cross-section taken on line 11 11 of Fig. 10.
In the different figures A A A A are my die-blocks provided with the convex working surfaces B.
O is the die-plate.
D D D D are adjusting-wedges bearing against the sides of the blocks A and the inner surface of the recess formed in the dieplate 0, each of said die-blocks being provided with a concave edge, as shown, closely fitting againstthe convexity of the adjoining die-block.
D is a wedge or stop fitting between one of the wedges D and one of the die-blocks A. Said stop D, acting in conjunction with the wedges D, serves to secure the die-blocks in position, the wedges D holding the die-blocks from moving in one direction, while the stop D prevents their motion in the opposite direction, as may be readily understood.
In Fig. 3, E E are wedges bearing against the ends .of two of the die-blocks A, which wedges are used in adjusting and taking up the lost motion of the die-blocks within the recess formed in the die-plate O.
In Fig. 5 four wedges E are shown, corresponding to those similarly lettered in the other figures, and in Fig. 7 are four similar wedges marked E.
In adjusting my die, as shown in Figs. 1, 2, 3, 5, and 6, for a given size I prefer to make the first adjustment by means of one or more of the wedges D in connection with the stop D, after which the wedges E E are tightened up, thereby completing the adjustment. The adjustment of my die (shown in Fig. 4) is made by means of the wedges D and the stopwedge D. The die shown in Fig. 7 is adjusted by means of the wedge D and the end wedges E. The die shown in Figs. 8 and 9 is adjusted by means of the plain wedges D and the stop D and that shown in Figs. 10 and 11 is adjusted by means of the set-screws P and Q.
Fig. 7 shows an alternative arrangement 0 my die-blocks, in which three of the wedges D are dispensed with,-the Wedges E E E E in this case serving a similar purpose, said wedges E being contained within an offset formed in the die-plate, as shown, in order to properly preserve the position of each with relation to the other parts. In this case I prefer to use one wedge similar to that hereinbefore described and which is lettered D in Fig. 7, above referred to, and another similar one may be used to act in a contrary direction, as
t on said blocks, one of said clamping-surfaces may be readily understood.
In the case shown in Fig. 7 the wedges E" serve for the adjustment of the die-blocks and also for keeping them in close cont-act with each other after the manner hereinbefore described. This arrangemont of four wedges E may, however, be modified by omitting two of said wedges, the only difference in this case being that the draw-hole will not remain central with respect to the die-plate; but where this is immaterial the latter arrangement is to be preferred, as it is in the direction of simplicity.
F F are threaded bolt ends forming part of the various wedges. G Gare the nuts of the same, while J J are washers interposed between said nuts and the rear surface of the die-plate 0, said bolts passing through the slotted holes I I, formed in the die-plate.
Referring now to Figs. 8 and 9, D D D D are plain wedges for adjusting and securing the die-blocks A, and D is a stop for adjusting and holding said die-blocks in the opposite direction.
As shown in Figs. 10 and 11, P P P P are set-screws for adjusting and securing the dieblocks A, and Q Q are other set-screws for securing and adjusting the same endwise, and in this construction the die-plate O is made thicker to accommodate the set-screws without interfering with the support of said plate Within the head-block K. (Shown in Figs. 1 and 2.)
K is a head-block of a drawing-machine provided with a segmental spherical socket K, into which the die'plate O is fitted, as shown in Fig. 2.
L is a hinged gate attached to the headblock K by means of the bolt M, said bolt being provided with a key N for retaining it in place.
0 is a locking-bolt which by means of the nut P secures the hinged gate L to theheadblock K, said hinged gate being provided with set-screws H H H H, working in threaded holes therein, their ends bearing against the die-plate O for the purpose of adjusting the same in proper position within the headblock.
In order to provide "a ready means for setting my die-blocks to the size required, I may use a male templet or block of the same size as that which is proposed to be drawn, said templet being inserted within the draw-hole and the die-blocks brought into firm contact therewith by means of the wedges or setscrews, as above described, after which the templet may be withdrawn and the die is ready for operation.
