WIRE-SHAPING MAoHiNE.

Application filed February 28, 1922. Serial No. 539,841.

To all whom it may concern:

Be it known that we, GUsTAv W. LANGE and GUSTAV M. LANGE, cit zens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Wire- Shaping Machines, of which the following is a specification. I 1

This invention relates to a Wire shaping machine and more particularly to a machine for imparting to wire of circular cross-sec- .t'ion rectangular cross-section, in which latter shape. it is suitable for making horseshoe nails as well as various other articles.

3 One of the objects of the invention is to provide a machine of this character which will give the wire a practically perfect rectangular or other desired. cross-section and at the same time avoid impairment of its tensile strength;

A further object is the-provision of a sim-' ple, compact and inexpensive wire shaping machine which combines maximum production with a minimum expenditure of power and labor, and which requires a comparatively small floor space.

A still further object of this. invention is to provide the machine with simple and convenient means for adjusting the wire-forming dies to accommodate stock of different sizes.

In the accompanying drawings: Figure 1 isa side elevation of the machine. Figure 2 is a top plan viewthereof. Figure 3 is an enlarged fragmentary transverse section on line 33, Fig. 2. Figure i is an enlarged fragmentary longitudinal section on line i H, Fig. 2. Figures 5 and 6 are enlarged fragmentary transverse sections on the correspondingly numbered lines in Fig. 2. Figure 7 is a sectional top plan view .of the driv ing mechanism of the forming dies. Figure 8 is a vertical section .on' line 8'8, Fig. 3. Figure 9 is a horizontal section on line .9-9, Fig. 8, Figure 10 is a front view of the edging or finishing dies of the machine. Figure 11 is a vertical section of one of the bear ing bushings of the forming die shafts. Fig.- ure i2 isa sectional elevation of oneof the forming die shafts and its bearing bushing. Figure 13 .is .ape-rspective view of the die I shaftsections and coupling member, showing the parts separated.

Similar characters of reference indicate corresponding parts throughoutthe several views. I

In its general organization, this machine comprises a support or table for its working parts; two rows of forming dies or rolls ar-- ranged lengthwise of the machine on either side of the table, the dies on one side thereof serving-to shape or cold roll the wire and feed it in one direction and the dieson the other side serving to cold-roll the wire and feed it in the opposite direction; means for driving at progressively increased speed the successive sets of forming dies, to compensate for the elongation of the wire as it advances through the machine. I

20 indicates the bed or table of thema-H chine supported on legs 21.

Mounted upon the table and extending lengthwise of the machine are two substantially parallel rows or series of forming dies or rolls, each preferably consisting of three sets 22, 23, 24:, which are shaped to convert wire of circular cross section into wire of rectangular or other desired cross section,

these dies serving at the same time to feed the wire through the machine. a The dies 22, 24 of the end sets are preferably rotatable about a vertical aXis and arranged side by side transversely of the machine, while the dies 23 of the intermediate set are rotatable about a horizontal axis and arranged one above the other. The several forming dies are provided in their peripheries wlth annular grooves25', the companion grooves of each set having the proper contour to form together a substantially rectangular opening between them through which the round wire,

Thewire is condensed and gradually elongated as "it passes throughthe several sets 24: are

lot

' Mounted on this driving shaft is a bevel gal pinion 33 which meshes with a gear 39 journaled at its lower end on a vertical stub shaft 40 secured to the table, as shown in Fig. 3." Connected with the gear 39 to turn therewith is a pinion 41 which meshes with two comparatively large gear wheels 4-2, d3, mounted on shafts ist, 45, located on opposite sides of the shaft 40,2s shown in Fig. 7. Also mounted on the shaft 4 lare two gears 46, 47 of different diameters which mesh, respectively, with pinions 43, {i9 mounted on the shafts 26, 26 of the first set of forming dies at one side of the table 20 and the last set of dies on the opposite side thereof. The shafts 27 of the companion dies of these sets are provided with similar pinions 51, 52, thus rotating these dies at the proper speed and in opposite directions to feed the wire successively through the two series of dies. Mounted on the shaft 45 are two gears 53, 54 of different diameters which mesh, respectively, with pinions 55, 56, mounted on the shafts 26, 26, of the last set of forming dies at one side of the table and the first set of dies at the rear side thereof. The shafts 27 of the companion dies of these sets are provided with similar pinions 57,

58, thus rotating these dies at the desired speed and in opposite directions to feed the wire through the machine.

The intermediate set of dies 'of each row is also driven from the main drive shaft 35. For this purpose, the latter is provided at or near opposite ends with sprocket wheels 59, 59, and mounted on shafts 60, 61, projecting from opposite sides of the table are corresponding sprocket Wheels 62, 62. Sprocket chains 63 pass around the sprocket wheels 59, 62. Mounted on the shafts 60, 61 are pinions 64, 65, respectively, the pinion 64- meshing with a gear 66 mounted on the end of thelower horizontal shaft 31 of the intermediate set of dies 23 at the front side of the machine, while the pinion meshes with an idler gear 67 which in turn mesheswith a gear 68 mounted on the end of the lower horizontal shaft 31 of the correspond ing set of dies at the opposite side of the machine. Motion is transmitted from'the lower die shaft 31 to the upper die shaft 30 through the medium of intermeshing gears 30 and 31*.

Means are provided for taking up the wear of the forming dies and also for replacing them by dies to suit wires of different sizes. This is effected without interfering with or throwing any of the gears out of mesh, and as shown in the drawings, these devices are preferably constructed as follows: 7

()ne of the upper shaft bearings of each set of end dies 22, 2et say, the bearing 29 of the shaft 27, is adjustable toward and from the bearing 28 of the shaft 26 and the two upper shaft bearings 32 of the intermediate set of horizontal forming dies 23 are likewise adjustable toward and from the corresponding lower shaft bearings 33. To permit such adjustment of these bearings and their die shafts, the latter are divided 'between their driving pinions and said bearings into two sections 70 and 71 which are universally and slidably connected together by an intermediate coupling memberordisk 72. The latter is provided on opposite sides with tongues 73 arranged substantially at right angles to each other, while the opposing fiat ends of the shaft sections 70 and 71 are provided with corresponding grooves 74 for receiving said tongues. This construc tion, while compelling the sections of the die tically movable wedge 6 interposed between the straight inner wall 7'? of the base 75 and the inclined outer wall 73 of said heating block. The upper end of this wedge is provided with a lug 79 having a slot 80,

through which passes an upright bolt 81 projecting from the top of the bearing block. This lug is adjustably clamped between a pair of nuts 81 engaging said bolt.

The adjustable bearings 32 of each die shaft 30 are also in the form of bloclfs which are guided for vertical movement ina base or holder 82 suitably secured to the table 20."

A horizontally disposedwedge 83 similar to the wedge 7 6 serves to adjust these bearing blocks as desired.

In traveling from the first to the second row of forming dies, the wire passes around a freely rotatable guide-drum 8 1 mounted on the rear end of the table 20. The wire, after passing through the several forming dies is wound upon a rotary take-up drum 85 mounted at the front end of thetable in line with the second rowv of dies. This take-up drum is controlled by a suitable clutch86' having a hand lever 37 for operating it.

Lil

Located adjacent to and in line with the second set of forming diesis a pair of edg ing or finishing'dies or rolls 88, arranged one above the other. The lower edging die is mounted in a fixed bearing-'89, while the upper die is preferably mount-ed in a vertiy ducting groove 92 which starts near the lower end of the bushing and extends nearly to its upper end, as shown in Figs. 11 and 12. The respective die shaft is provided with an axial oil passage 93 which extends downwardly fromits upper end and communicates at its lower end with the first turn of the oil groove 92. As the shaft rotates, a column, of oil is caused to ascend through thespiral groove and overflow into the central passage 93, of the shaft, from. which it is discharged by gravity at the first turn of said groove, thus effecting a continuous circulation of the oil around the shaft. To

further assist this circulation, the shaft may be provided in its side. with a longitudinal groove 94 through which the oil is fed upwardly due to the communicating spiral groove 92 in the bushing 91.

I The wire is conducted from one set of dies to the next by suitable guides such as the guide-tubes 95 shown in the drawings. In the operation of this machine, the round stock of wire is supported on a suitable reel, not shown, and its end is threaded through the several forming dies of the first row of the machine. It isnext passed around the freely-rotating drum 84, thence threaded through the several forming dies of the second row and the finishing dies 88, and finally attached in any suitable manner to the take-up drum 85. Motion is then transmitted to the several dies which rotate Upon reaching the finishing 'dies 88, the wire is practically shaped to the desired cross-section, but it is desirable to employ these additional dies which function to square up the edges or corners of the wire, pressing the same into uniform shape and correcting any remaining irregularities the-rein. v

By its passage'through the series of shaping dies, the wire is compressed and condensed; It is not however drawn or stretched during these shaping operations and its tensile strength is therefore increased -rather thanimpaired,as is the case when the wire is drawn. By disposing the several sets of dies in a plurality of substantially parallel rows or series, and providing means for guiding the wire from the delivery end of onerow'to the receiving end of the next, the course of the wire through the machine is doubled or reversed, instead of being straight from end to end of the machine, thus materially shortening the latter, rendering it more compact and requiring less floor space for it. Compared with machines in which the wire is shaped by drawing operations, this improved machineproduces a superior product and affords increased production. with less labor.

While our machine is herein shown and described as particularly adapted-for giving round wire a rectangular cross section, the forming dies may obviously be shaped to impart to such wire any other desired cross section, such, for instance, as oval, triangular, diamond, &c., according to the use or article of manufacture for which the wire is intended.

e claim as our invention:

1. In a wire shaping machine, the combination of a rotary shaft having driving means, two pairs of die-rolls arranged on opposite sides of said shaft, the die-rolls of each pair having their shafts provided with intermeshing gears, and a pair of gears of different diameters secured to the first- 'named shaft, one of the last named gears bination of a pair of parallel shafts, each carrying a driving gear, a driving pinion interposed betweenthe gears of said shafts and meshing with both of them, pairs of dierolls arranged on opposite sides of each of said shafts, the die-rolls of each pair having intermeshing gears, and a pair of gears of different diameters secured to each of said parallel shafts, one of the last-named GUSTAV WfLANGE.
