" appllcatoin is a division of our prior application, Serial No. 709,646, filed February 3,

One object ofthis invention is to provide a which the sidewalls of the inclosingcabinet' are provided with slots, thus permitting the dies to be strung upon the wire at spaced intervals beforev v inserting the .wire in the wiredrawing machine. A further object is to provide a wiredrawing machineoi the above nature having means fcir securely holding the final die in adjustable posi- .tlon in a die box to permit the proper casting of the wire as it is wound upon a finishing block after leaving the'machine. v f A further object is to provide a casting de-. vice of the above nature in which the flnal die box is capable of universal angular adjustment, and may also be moved vertically and horizontally. a

A further object is to provide a machine of the above nature which will be relatively simple in construction, inexpensive to manufacture, easy to install and manipulate, economical of power and floor space, and very eflicient and durable in use.

-With these and other objects in view there have been illustrated'on the accompanying drawings two forms in which the'invention may be conveniently embodied in practice.

Fig. 7 is a detail perspective view of the slotted mechanismv Wiredrawi'nd mechanism Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral III indicates the supporting frame of the machine which supports a cabinet" for housing the wiredrawing mechanism. The cabinet ll comprises a basin-like base II, a rear wall, not shown, and side walls ll.

The top of the cabinet n is closed by means 0! a thin curved hood member it, within which is journaled a roll-top door ll having slidable engagement in suitable opposed grooves provided adjacent the front slightly inclined edges 19 and to be drawn downwardly by a suitable handlelfla for completely sealing the front of the compart ment in the cabinet II, as showrrin Fig. 1.

. Final drawing die After leaving the final cone of the machine, the wire is passedthrough an open slot 58 (see Figs. 1 and 6) formed in the front of the right-hand wall it of the machine, and is delivered to afinal' drawing die 51 from which it is wound upon a finishing block It.

Casting mechanism j During wiredrawing, as the wire is processed through the several dies, the metal hardens and unless the final drawing die is positioned at the proper angle with respect to the finishing block It, the coiled ,wire will spring out to a larger diameter than the block on which it is drawn and the coiled wire when lifted fromthe block will become tangled up and diilicult to handle. In orderto overcome the above disadvantages, the

' present invention contemplates the provision of die-clamping screw employed in the casting Fig. 8 is'fa transverse vertical sectional view 'taken through the final die cup and showing the 5s die adaptor in place.

a mechanism to accurately adjust the position of the final drawing die 51', and thereafter firmly lock it in adjusted position.

i The casting" mechanism is generally indicated by the numeral Cl and is adapted to hold the final die ll in any desired position and angle 55 2 between the right cabinet wall it and the coiling block 50. The casting mechanism 6i, as best shown in'Figs. 2 to 6 inclusive, is adapted to be detachably secured to the right wall Id of the 5 wire machine.

The final drawing die 51 is located ina die cup. 62 which is adapted to rock upon a .pair of lateral trunnions 63 and 6d. Mounted upon the die cup 62 is a detachable wall plate 65,-and said cup is covered by a top hinged lid 66. The wall plate 65 is provided with a tapped outwardly projecting boss 65a which is adapted to receive a special die clamping screw 61 (see Fig. 7) which serves to tightly clamp the final die 51 against the right wall 620. of the die cup 62. The clamping screw 61 consists essentially of a threaded shank 10 having an enlarged flanged head II at one end, and a reduced portion 12 at its opposite end for abutting against the face of the die 51. The flanged head is provided with a plurality of equally spaced radial recesses 134m its circumference which maybe engaged by any suitable tool, such as a pin wrench; for tightening the screw 61 against the die 51. The wire a: is adapted to pass through a longitudinal hole 68 in the screw 61, and in order to facilitate the placing of the already strung die 51 in the die cup 62, said screw 61 is provided withia longitudinal open slot 14 extending the entire length thereof and forming a radial passage for the wire a: into the hole68. A vertical slot 15 is provided in 'the upperpart of the detachable wall plate 65, and by indexing the slot 14 in the screw 61 to aline with the slot 15 in the wall plate 65, the wire a: and the attached die 51 may be readily dropped into the die cup 62, after which the screw 61 may be turned into die' clamping position. The slots 14 and ,15 will ordinarily be out of alinement and the 40 wire will be positively prevented from, slipping out of place.

The die cup 62'is mounted to swing on a horizontal axis by means of the trunnions 63 and 64 which have pivotal engagement in an open pan-shaped box 16. -The rear trunnion 63 is journaled in a hub 11 formed integral with the rear wall of the box 16 while the front trunnion 64 is journaled in a set-in portion 18 detachable with the front wall of said box 16.- As shown in Figs. 2 and 5, the. trunnion 66 protrudes through the front wall of the box 16 and is provided with a transverse handle rod 80 to facilitate the rocking ofthe die cup 62 vabout its horizontal axis. The upper \part of the set-in wall 18 is provided with a split bifurcated section '8I, the side jaws of which are adapted to be clamped tightly upon the trunnion 64, by means I -of a-transverse set screw 82.

In order to prevent any' lubricant from spattering upon the, winding block 58, the cover lid 66 previously referred to, and which is hinged to a tubular section 03 on the rear wall of the die cup 62 by means of a 'hingepin 84, serves to completely seal the final drawing die .61 there- I 55 within. The front edge of the Loover lid 66 may be provided with a handle lug 85 for facilitating the manipulation thereof. The pressure of the die 51 upon the wall 62a of the die cup 62 will, of course, be enchanced by the pull of the wire L mpassing through the die 51, thus increasing the.

tightness .of its liquid seal between said adjacent surfaces to prevent any lubricant from passing by the die.

After the wire a: leayes the die 51, it passes 35 through a tube-likeextension 86 mounted within aromas;

a tubular boss 62b, forming an integral part of the cup-62 (see Figs. 3. 5 and 9). The extension 06 is adapted to protrude through an enlarged aperture 81 inthe end wall of the die cup box 16. v I 5 In order to supply a steady stream of lubricant to the final drawing die51, the cover lid 66 of the die cup 62- is provid ed with a substantially central vertical nipple 88, to which-may be attached a flexible tube 89 leading to a suitable ad- 10 justable flow regulating stop-cock 90 located on the outside right wallit of the machine, and having suitable connection with the lubricating supply pipe 29a (not shown) within the cabinet II. By reason of the fact that the final die 51 in 15 both forms of die cup is clamped intight face contact with the right wall 62a (I90) of said die cups, it will be impossible for any lubricant to escape from the die cup, and the wire as it leaves 7 the die box is' thus maintained in a dry condi- 20 tion,an important advantage in wiredrawing machines.

a As noted in Figs. 5 and 7; the reduced end 12 of the'clamping screw 61 is providedwith a pair of crossed grooves 9! cut into its face surface 25 whereby the lubricant flowing into the diecup 62 will have direct access with the center hole it enters the final die 51. A suitable drain hole 92 is provided in the base of the die cup 62 where- D by the lubricant will be drained therefrom into the die cup box 16. The base of the box 16 in turn is also provided with a drain aperture 96, into which is fitted a pipe nipple 9511., upon which is attached a flexible hose 95 for conduct-J 35 me the drained lubricant back into the main casing of the machinethrough an aperture '96 in the wall I4. Q The final die c ip box 16 is provided with a depending cylindrical stud 91 pivotally engaged :3 within a split hollow cylinder 98 concentrically formed in a boss '99 forming an integral part of a longitudinally sliding bracket I00. The boss 99 is formed with a pair of lateral ears IOI and I 02 I slightly spaced apart to provide a clearance slot 45 I03 therebetween. j I In order to lock. the. die cup box 16 inadjusted position "on the vertical axis of the stud- 91, provision is made of a. transverse binding screw I04 having threaded engagement in the ear IOI. It is to be noted that the vertical axis of the g depending stud 91 of. thenbox- 16, the horizontal axes of the two trunni'ons 63,and 64, and the horizontal axis of the wire a: intersect each other at a common point located approximately in the center of the die 51 (see Fig. 5) By means of this construction, the wire a: in passing through the final diewill be bent the exact amount to ,give it the proper cast" before being wound 60 upon the block 58. Y

It will be understood from the above thatthe final die 51 not only has a universal pivotal movement about 'both vertical and horizontal axes, but it is also possible to adjust the final die vertically. As will be described later, the final die also may be given a horizontal adjustmentin' all directions. 7 g

In order to accomplish t e vertical adjustment, micrometically or'by sma increments, the under side of the box 16 is provided with an integral boss I05 having an arcuate vertical face I06 within which is cut an arcuate rectangular groove I01 for receiving the'fianged head I08 of a stud screw I09. The screw I09 is threadedly engaged any desired finely adjusted position (see Fig. 2).

' turn is detachably secured as by cap screws H4 The sliding bracket I is slidably mounted upon an angular supporting bracket H3 which in to a 'substantially'heavy boss H formed integral with the right side wall 'I4 of the machine; In order to anchor the sliding bracket I00 in adjusted longitudinal position upon the bracket I I3,

, the bracket" I00 is provided with a pair of T- bolts H6, H8 located on opposite sides of the vertical boss 98 and adapted to engage in a longitudinal 'T-slot II1 formed in the bracket H3. The object of adjusting the sliding bracket I00 andsupported parts as a unit, is to set the final die 51 as close as possible to the take-up or finishing block" 58, it being understood that vari ious sizes of take-up blocks'may be interchange--v r ably used on the same machine.

Fig. 2 illustrates in full lines the smallest size 1 of block 58 which may be used andthe same block is illustrated in Fig. 3 by dotted lines. The largest size 0f block which may be used on the machine is" indicated imFlg'. 3 by the dot-and-' dash line 58a, and in Fig. 1 by full lines. The die holding unit 6| is shownin full lines in Figs. 2 and 3 in the proper position for winding upon the largest size of block 58a. The dotted outline of the die cup box 16 shown in Figs. 2 and illustrates the proper position for setting the unit when the smallest size of block 58 is employed.

' 'In order to permit the block 58 to be adjusted laterally so that the cylindrical surface of the block will be in tangential alinement with the wire as it is delivered from the final die 51, the

, block housing H8 is slidably supported upon the supporting frame I0 01 the machine, and is provided with a suitable screw mechanism I operated by means of an external crank handle I2I which may be manually operated to forward- 7 1y or'rearwardly move the block housing H8 and elongated (see Fig. 6).

rigidly secured to the wall boss H5 and supports surmounted block 58 (or-58a) to any desired 10- K cation.

In order to produce a close lateral adjustment of the casting mechanism 6| for properly ,alining the die 51 with the roughly adjusted block 58, the holes I22, I22 in the angular bracket H3 surrounding the cap screws H4 are horizontally H A vertical plate I23 is a horizontal stud screw I24 held in rotatable engagement therein by means of a collar I25 fixed to the shank of said screw I24 on the opposite side of said plate from the head I24a of said screwJ The shank of the screw I24 is/threadedlyen- .gaged in a hole I26 tapped into theside-oi' the single bracket H3. From'the above construction, it will be obvious, that by slightly loosening the bracket screws H4,

and turning the head,i24a of the screw I24, the

' bracket I I3 and entire casting mechanism 6| may be minutely adjusted laterally, as a unit. I

It will thus be seen that the final .die ofthe tudinal and horizontal adjustment.

pan-shaped top of the top being provided with an upright outer rim within which is a groove I28 for conducting the lubricant rearwardly into a catch basin I29 formed in the upper part of the bossI I5 (see Fig. 3). As clearly shown in Fig. 6, the bottom of the basin I29 is formed with a. pair of inclined surfaces I30 which meet at the center and permit the lubricant to flow through a drain aperture I3I provided in the wall I4 and be drained back into the cabinet I I.

Adaptor block for final die In order to facilitate the setting of the final die 51 within the die cup 82 during the stringingup operation 'of the machine, provision is made of an adaptor block' I32 which, as shown in Figs.

angular bracket H3, said b 8 and 9,- is substantially rectangular in shape and N is detachably seated within the die cup 62 under the die 51. The adaptor block I32 is provided in its upper face with a semi-circular cut out portion I33 for receiving the die 51, and irom its bottom extend a pair 0! depending dowel pins I34, I34 for engagement in a pair of corresponding holes provided in the base of thedie cup 62. It will beunderstood that a number of blocks I32 having different size cut-outs I 33 may be provided for the die cup' so as to selectively accommodate the various sizes oi. dies thatmay be used. I

In use it will only be necessary to drop the die already strung upon the wire, a: in place, and tighten the clamping screw 61 to hold said die rigidly in place within the die cup 82.

Preferred form of final die cup In Figs. 10, 11, and 12 is shown the preferred form of holding cup I35 for the final die 51 wherein the special die clamping screw 61 and the adaptor block I 32 of the first form of the invention have been omitted. The preferred die cup 'I35-is providedwith a tubular extension I30, and oppositely extending t'runnions I31 and I38 for pivotal engagement in the final die cup box 16. The-tubular extension I36 is fitted into an apertured boss I39 formed on theoutside of the die cup and integral with the wall I40 thereofj.

The inner side of the wall I40 is provided with I a countersunk circular socket I for receiving a closely fitting split annular ring I42. The die cup I35 is preferably made semi-cylindrical in shapeandi is provided on its curved portion with 'a pair of headless radial set-screws I44, I 44. Each square-headed set screw I41 having threaded'engagement in the upper section of the wall 440. The inner end of the set screw I 41 is also provided with a reduced point I48 for engaging-in a corresponding socket provided in the circumi'erence oi the upper bendable section M211 of the annular ring. It will be obvious from the above. construction, that merely by screwing up the set screw I41, the die 51 which is positioned within the annular ring I42 will be rigidly clamped in die 51 in the casting" mechanism 6|. Inorder Operation -to set up the final die 51, it isfirst' necessary end of the wire may be inserted thro'ugh the to adjust theclamping screw 61 so that the longitudinal'slot 14 thereof will be in line with the slot 15 formed in the wall plate 65 of the die cup 62. With the parts in this position, the initial tubular extension 86 and the final die fill readily dropped into position within the seat I33 of the adaptor block I32. It is' to be understoodthat the operator will leave an ample length of wire beyond the final die to allow said wire to be woundabout the drawing block 58 asufiicient number of times. soas to prevent slipping when the block 58 is rotated. With the final die 57 thus properly set in the adaptor block I32, the clamping screw 61 may then be tightened against the die 5] so as to hold it tightly against the .die cupwall 62d. The die 51 may then be adjusted at the proper angle and in the proper horizontal and verticalposition to give the wire the proper cast as it is delivered to the block. 58; by

manipulating the mechanism in the casting mechanism 66. I

In the operation of assembling the die 5'5 to the preferred form' of die holding cup i35,f shown in Figs. arid 11, it will be understood. that the split annular ring M2 will first be 'placed'in the socket Ml of the cup H35. The screws'ldd, 3% will then be inserted and" rotated with the points M5 pass into the corresponding apertures in the ring M2. The upper bendable section 6 32a of the ring M52 is normally in its outermost sprung position when the die 5? is not in place. The end of the wire upon which the, final die] 51 has been previously, strung may then be inserted through the tubular extension ltd, permitting the final die 5? to he slipped into the split ring 562.

The set screw id? will then be screwed down and will force the upper section Mitt downwardly for clamping the die 5? tightly. in its properly set position. The proper cast for the wire may then be readily obtained by adjusting the die cup 535 in the same manner asv described above. for'the first form of the invention.

An important featurev oi the present invention. lies in the fact that the drawn wire beyond the final die may be cut oil? from the remainder of I ".the coil still in the machine in any desiredlength and removed from the block without disturbing the setting of the dies or casting mechanism in 'tached to the block any way. The remaining wire may then. be atand the drawing processcon tined as before. 4
