My invention relates to a reel for coiling wire such as is used for taking up the wire which is discharged by the last stand of a rolling mill Reels of this type are operated either on the Gar- 5 rett or on the Edenborn system. In the former, the nozzle which delivers the wire to the reel is stationary and the basket in which the wire is deposited in turns is rotated, whereas in the latter the nozzle is rotated and the basket is stationary. Each system has its particular merits and is therefore preferred to the other according to the conditions in which it is to be used in practice.

With a reel according to the Garrett system wire of any cross-section can be wound up, whereas a reel according to the Edenborn system can only be used with wire of round cross-section. On the other hand, with a reel according to the Edenborn system the wire is positively guided when deposited inturns in the basket so that the turns are not liable to jump out of the basket even when the latter is rotatedathigh speed. Furthermore with a reel according to the Edenbornsystem, the revolving masses are not so big 5 as with a reel according to the Garrett system.

It is an object of my invention to provide-a reel for coiling wire which can be selectively operated either on the Garrett or on the Edenborn system. This I accomplish by removably mounting the rotating parts of each system,--i. e. the basket with the Garrett system and the nozzle with the Edenborn system-on the driving shaft of the reel so that each of them can be easily replaced by the other at will. In this way, I can rotate either 5 the basket or the nozzle and thus operate the reel either on the Garrett or on the Edenborn system.

It is a further object of my invention to provide a reel-of the type set forth in which the turns of the coil are formed within the same space of the reel both with the Garrett and the Edenborn system. This I accomplish by so arranging the nozzle used with the Garrett system that its outlet end lies in the plane which is described in space by the outlet end of the nozzle used with the Edenborn system, and by further arranging the basket used with the Garrett system in the coiling space of the Edenborn system. With this arrangement the other members of the reel, i. e. the means for tilting the basket and for feeding water to the basket for hardening purposes can be used without variation with both systems.

It is a. further object of my invention to provide a reel of the type set forth in which the parts which have to be replaced when the reel is transformed from the Garrett system to the March 3, 1934 Edenborn system arid vice versa are easily accessible. For this purpose I provide each of these parts with a coupling head by which the respective part is mounted on the top end of the driving shaft of the reel which projects above the coiling space.

It is a further object of my invention to provide a reel of the type set forth in which the electric driving motor is mounted directly on the driving shaft without requiring additional space. This I accomplish by arranging the motor within the coiling space so that it is surrounded by the latter.

In this case I prefer to provide a cooling jacket around the motor in order to protect the moto against the heat of the coil.

With these and other objects in View, I will now describe my invention more fully in detail, reference being had to the accompanying drawing in which Fig. 1 is a vertical section of a reel, according to my invention, which is adapted for the Garrett system, and

Fig. 2 a vertical section of the same reel adaptspace i and is there provided with a key 5 and.

fastening screws 6 for a purpose "which will presently appear.

In case I wish to operate my reel on the Gar rett system, I make use of a coupling head i i (Fig. -1) carrying the basket 8. The coupling head I is mountedon the shaft ll by means of the key 5 and the screws 6 in a manner which will appear from Fig. 1 so that the basket 8 will depend downwardly. I complete the arrangement by mounting a stationary nozzle 9' on the cover ill of the reel.

In case I wish to operate my reel on the Edenborn system, Imake use of a coupling head I" (Fig. 2) carrying a nozzle 9". The coupling head I" ismounted on the shaft t by means .of the key 5 and the screws 6. Since in the Edenborn' system the means which take up the coil are not rotated I need not provide a separate basket in this instance; The nozzle 9 is so shaped that its outlet end lies on the same level as the outlet end of the nozzle 9' in Fig. 1 and at. the same distance from the axis of the reel.

It vwill be readily apparent that I have thus provided a reel for coiling wire which can. be

easily transformed at will into one of the Garrett or one of the Edenborn type. It is only necessary for this purpose to exchange the two coupling heads 1 and 'l" and the parts associated with them.

The coupling head 'I is also fitted with stop pins ll having notched ends. I provide these pins in order to prevent the uppermost turns from rising from the coil. The pins 1 I and the nozzle 9" are slidably mounted so that when the reel is tilted they can be moved out of the way thus to clear the path for the discharge of the finished coil from the coiling space. The cover I0 is controlled by known means so that it will open only when the reel has reached almost its downward position. As these means are known I need not describe them here.'

Tilting of the reel is accomplished by means of trunnions I2 which are arrangedabout midway the height of the coiling space I so that the reel will be normally kept in balance. One of said trunnions is provided with a. longitudinal bore l2 (Fig. 1) through which water for hardening and cooling purposes may be fed to the reel. The cooling water is fed to the cooling jacket 3 by means of a tube I 3.

It will be further noticed that the basket 8 shown in Fig. 1 is provided with bores M for the hardening water as more fully described in my Patent 1,977,989. I5 is a ring disposed below the basket 8 which prevents the water coming in through the bore l2 from passing around the basket 8 so that the whole water is guided to the bores l4. 7
