. adjustable mechanism by means of which either left hand or right hand coils can be formed.

The more detailed objects of this invention will be apparent from the following description of several embodiments thereof when taken in connection with the attached drawings.

'I'his invention resides substantially in the combination, construction, arrangement and relative locations of parts as will be.decribed in detail below.

In the accompanying drawings,

In the manufacture of wire, as for example copper wire, man1 users thereof require that the wire be put up in the form of open coils rather than wound on spools or reels. Furthermore, in adapting these coils to certain uses the users frequently require that the wire be ,formed into left vhand coils as distinguished from the .more usual requirement that they be formed into right hand coils. The coiling machines as commonly employed for forming right hand coils are not adapted, at least not without considerable change,

sult thatseparate machines have been considered preferable for the forming of the two kinds of coils. This, of course, requires extensive and 'undesirable duplication of machines in order to equip a factory for the production of both types o! coil.

In accordance with this invention there is provided in a single machine mechanism which may be easily adjusted so that the same machine may be employed to form either left hand wound or right hand wound coils. The'manner in which' this is accomplished will be quickly understood from the following description in det-ail of two 'embodiments of the invention.

Referring` first to the structure illustrated in Figures 1 to 6 inclusive there is illustrated at I the last capstan wheel shown mounted on a power driven shaft 2. The wire W passes from the next to the last drawing die in the wire drawing machine to and once or more times around the capstan wheel I, which being power driven by mechanism not shown, acts to draw the wire from the next to the last drawing die. The wire W passes from the capstan wheel I to and through a. passage or space between a pair of idler guide wheels 3 which are freely and rotat` ably mountedon a bracket 4 mounted on the end wall of the casing I. 'I'he wire engages one or the other of these idler wheels I, depending upon whether a right hand or left hand coil is being formed, as will be referred to again.

The end wall of the casing has an opening and the region of the opening is preferably reinforced as indicated at B in Figure l, to form a base upon which the adjustable holder for the ilnal drawing die is mounted. Resting against 'this base is a wedge-shaped block 1 which is attached to the base by means of a. pair of locking bolts i which lie in the radially aligned slots/in the block. Attached to the outer face of the block i is aplate 8 which is attached thereto/by means of bolts 8' 1 which pass through elongated slots in the plate to the formation of left hand coils, with the re- 8. As is clear from Fgure 5, by means of this construction the pla 8 may be adjusted verti- 4cally within limits above the face of the block 1. 'I'he plate I, as is clearly shown in Figures 4 and 6, is provided with a passage aligned with the passage in the housing 5 and the block 1, which is spherical in form to provide a seat for the die block holder I0 which is complementarily shaped so. as to rest in this seat. The holder I0 is attached to the plate 8 by four screws I2 and cooperating washers Il, so that it may be ley/ed to the plate 8 with its longitudinal axis a any desired angle with respect to the plane of the plate 8. This holder I0 in actual use is only subjected to slight angular adjustments in order to properly align the die I3 which is mounted and locked therein by means of a tubular locking bushing I4. The die I3, of course, has a passage through it in accordance with usual practice, of a diameter such that when the wine is forcibly drawn therethrough it will be drawn out into a wire of nner gauge, which, of course, will be the final wire size. v

The wire W then passes to the coiler block which is power driven and provided with mechanism for causing it to rotate either in the right hand direction or the left hand direction, that is clockwise or counterclockwise. as viewed in plane (Figure. 2). The coiler block consists of a truncated conical tubular element. Il which is provided with an internal re-entrant hub I! by means of which it is locked on a power driven shaft I1. Bolted to the lower end of the tubular element Ii is a skirt I8 having a conical mainbody. The coiler block, comprising the members I5 and Il as herein disclosed. isshown inthe formcommonly used in this art. The flanged terminal end of the skirt Il is inclined at a slight angleradially, as clearly shown in Figures 1 and 3, and the wire is delivered to the coiler block where this flange portion joins with the main body portion. Thus', in accordance with the usual practice each succeeding coil is delivered into the resulting fillet of annular form, and pushes the preceding coil upwardly, the block being slightly tapered, as shown, so that its upward movement loosens the succeeding coils as they are formed and travel upwardly.

The shaft is journaled in bearings I9 mounted in a suitably shaped supporting member 25'. The lower end of shaft I1 is provided with a bevel gear 2l which meshes with a pair of companion bevel gears 2| and 22. The gears 2| andv22 are freely rotatable in the bearings 23 and on the shaft 28 which passes through them and is journaled at one end, as shown, in the bearing 2S. Splined on the shaft 28 in the space between the gears 2| and 22 is a' clutch sleeve 25 provided with clutch teeth on its endsv to cooperate with similar clutching teeth on the adjacent faces of these gears, as clearly shown in Figure 3. Pins on the ends of the-arms of yoke 2i engage in an annular groove on the surface of the clutch sleeve 2l. The yoke is mounted through which the driving power for the coiler is provided.

In the operation of this machine, assuming that shafts 2 and 28 are rotating, the wire-passes from the capstan 8|, which pulls it from the preceding die to and through the final die I3 and around the coiler block which is revolving. Assuming that lever 3| has been turned to proper position, clutch sleeve 25 will connect the correspo ding one of the pair of gears 2| and 22 to the shaft 28, with the result that the blockV will revlvelthrough power applied by the gear 20. Assuming that a right hand coil is being formed, as indicated in Figure 2, the coiler block 75 will be revolving in a clockwise direction and the wire after leaving the capstan wheel I will engage the uppermost (Figure 2) of the two idler wheels 3 so that it can be deected to the upper side of the coiler block (Figure 2). If it is desired to prepare a left hand wound coil, the operator removes screws 9 so that the wedge-shaped block 1 may be reversed from the position shown in full lines in Figure 4 to the dotted line position shown in the same figure. It is attached in this position and plate l is attached thereto by means of the screws 8. By the proper adjustments of the blockl 1 and plate 8, because of rthe slotted passages for the corresponding locking screws, the die may be properly aligned. In adjusting the apparatus for the formation of either type of coil the die blck holder I9 can have its longitudinal axis properly aligned with the path of travel of the wire by loosening and again tightening the screws I2. yBy reversing the wedgeshaped block 1 the parts will be aligned so that the wire W nowengages the lower idler wheel 2 (Figure 2), so as to be delivered to the opposite side of the coiler block. Lever 3| is repositioned so that the clutch sleeve 25 now engages the other of the gears 2| and 22, with the result that the coiler block is caused to revolve in the opposite direction. Thus by those few simple adjustments the machine can be quickly adapted for the for-- mation of either right hand or left hand coils.

For the operation of the machine'at different speeds the change gears, including the gear 2l, can be properly selected and when coils of different sizes are made coiler blocks of proper diameter can be mounted on the shaft |1. Thus the machine is universal in its application to the formation not only of coils of 'different wind, but of different sizes.

In Figures '7 and 8 is shown a modified ar- 'rangement for effecting similar changes by mechanism which makes these changes simpler. In this arrangement the guide wheels 3 are rotatably mounted at one end of a segment shaped plate 4I which is pivotally mounted at 45 on the end wall of the wire drawing machine. The plate 49 is provided with teeth 4| on its segmental edge, which mesh with a worm wheel 42 supported for rotation by means of a hand wheel 43. The

M'opening in the end wall in which,the plate 4B is 'mounted is providedlwith a curved cover plate 4l having `an, opening'inwhich the parts may move.

- Mounted on the plate 40zis a bracket 46 .to which the die block holdery plate 41 is attached. This plate corresponds to the plate 8 of the previous 'I construction and provides a socket for the holder 48 for the die block, which may be constructed as before. The coiler block and the drive mechanism is similar to that previously described but in the form shown the yoke 2B is directly provided with an extending arm 5|! pivotallymounted on the` housing so that the yoke can be moved to shift the clutch sleeve 25 directly in a manner similar to that previously described.

As will be apparent from the drawings in view of the previous description, the die block holder ciples of this invention may be modified in other physical forms, and I do not, therefore, desire to be strictly limited to the disclosure which has been presented in an illustrative sense, but rather to the scope of the claims granted me. In this connection it is pointed out that the principles of this invention need not necessarily be applied for use with a wire drawing machine since the apparatus is capable of use with any other machine from which strands are delivered. Likewise, the coiling mechanism may be used alone for ceiling purposes, as for example in forming coils from wire mounted on reels or spools..

The principles of this invention are not limited to a structure in which the coiler block is supported from below so as to stand erect, but it may be equally well applied to a machine in which the drive is above so that the coiler block hangs downwardly. Likewise, when desired, the axis of rotation of the coiler block may be arranged horizontally.

1. In a machine of the type described the combination including a power driven coiler block, means for causing rotation of the coiler block in either of two directions, a die holder, and means for selectively positioning the die holder for supplying a strand to the coiler block along either of two paths tangential to the coiler block at opposite sides thereofd v 2.
