Application filed December 15, 1923. Serial no. 680,819.

This invention relates to a mechanism for reeling paper and the like, and particularly to a mechanism and apparatus wh1ch is adapted to facilitate the wlnding of material on reels, the removal of full reels, and the positioning ofempty reels to have material wound thereon. I In the manufacture of paper, it is particularly desirable that the reels be changed with a minimum of disturbance of the remainder of the machinery, and it is an important object of this invention to provide a mechanism for easily and eifectively accomplishing this purpose with a minimum of wastage.

It is a further important object of this invention to provide a mechanism of the class described embracing power operated means for removing the empty reels into material receiving position and depositing the full reels on a supporting means from which they can be conveniently removed.

Another object of the invention resides in the provision of such a mechanism which is simple, durable and which may be easily operated.

Other and further important objectsof this invention will be apparent from the disclosures in the specification and'the accompanying drawings.

The invention (in a preferred form) is illustrated in the drawings and is hereinafter more fully described.

On the drawings:

Figure 1 is a side elevation of a paper reeling mechanism embodying the principles of the present invention.

Figure 2 is an end elevation thereof.

Figure 3 is an enlarged fragmentary section on the line 3-3 of Figure 1 with parts in elevation.

Figure 4 is a fragmentary top plan view of the mechanism. I

As shown on the drawings:

The mechanism of this invention ismounted upon suitably spaced upright frame members 1, and journalled in suitable bearings 2 on said frame members 1 is a shaft 3 which carries a rotatable material propelling drum 4. Said shaft 3 and drum 4 may be drivenin a. usual manner and from any suitable power source. v j v v The upper sides of the frame members 1 are provided with outwardly extending on said reels 13 is flanges 5 which aflord supports for the reel supporting and changing mechanism which will now be described. Supported on the flange 5 at one end of the drum 4 is a U- shaped member 6 having an annular bearmg flange 7 projecting inwardly therefrom to a point adjacent the end of the drum 4. Rotatably mounted on said bearing flange 7 is an annular reel supporting member 8, a

flange portion 90f which rotatably engages said bearing flange. A similar annular reel supporting member 8 is mounted at the other end of the drum 4 on a similar supporting means. i

The annular reel supporting member 8 is provided with a plurality of pairs of spaced projections 10 and 11 Which afford guideways for receiving trunnions 12 extending from the ends of suitable material receiving reels or winding drums 13. A Web 14 of material such as paper which is to be wound assed over the drum'4 and propelled there and is subsequently engaged around the reel 13 which is shown in dotted lines at position A in Figure 1. I have also indicated in dotted lines in Figure 1 a position A which is approximately the point at which the cut-ofi' end of the web of paper is first engaged around the reel 13, this being substantially the first point of contact of the reel with the drum 4.

It will be apparent that since the trunnions 12 are freely movable between the projections 10 and 11, that said reel and the material thereon will bear against the surface of the drum 4 and the web 14 of material to cause a rotation of the reel and the consequent winding of the material thereon.

The guideway afl'orded between the projections 10 and 11 permits movement of the axis of the reel toward or away from the axis of the drum 4 and it will be apparent that as material is wound on the'reel in position A the axis thereof will moveaway from the axis of the drum 4.

A succeeding .roll which is shown in Waiting position B in Figure 1' is held in position between rojecting members 10 and 11 positioned on t e rotatable member 8 at approximately 90 from the similar members supporting the reel in receiving position A, and said reel is held away from the web of material 14 and the drum 4 by the engagement of the trunnions 12 thereof with suit- "tion- B into starting position A an her 8 is provided with pairs of projecting members 10 and 11 which may be spaced at approximately 90, it will be apparent that when the succeeding reel 13 is moved into the position last mentioned, a succeeding pair of rojecting members 10 and 11 will e move into position B to receive an empty reel therebetween. The reel which is discharged from position A is received by supporting brackets 16, the outer faces of which are provided with receiving pockets 17 for the trunnions 12 of the discharged reel. It will be noted that the leading projecting members 11 are made somewhat longer than the followin projecting members 10 in order to gui e the trunnions 12 into the pockets 17.

' The followin projecting members 10 are formed outwar ly at their outer ends as indicated at 10 to facilitate the insertion of an empty reel between said projecting members and are made somewhat shorter in order toass the discharged reel.

he mechanism for driving the rotatable reel supporting members 8 will now be described. Formed on the flange 9 is an external ring gear 18 which meshes with a gear 19 journalled on a stub shaft 20 proecting inwardly from the frame member 1. Said gear 19 in turn meshes with a pinion 21 mounted on a shaft 22 journalled between the frame members 1 and connected to a short shaft 23 mounted in a suitable bearing bracket 24 outside of the frame member 1, and having a helical inion 25 secured to its outer end. Said he ical pinion 25 meshes with a worm 26 which is mounted on the lower end of a diagonal shaft 27, the upper end of which is rotatabl supported in a bracket 28 secured to the flange 5. Mounted on said shaft 27 above the bracket 28 is a bevel car 29 which meshes with bevel gears 30 and 31 loosely mounted on theshaft 3. Said bevel ars are adapted to be selectively connected or rotation with said shaft 3 to drive the shaft 27 therefrom in either direction by means of a usual sliding clutch member 32 which is operated by a pivoted lever 33 supported on a suitable bracket 34 extending outwardly from the U-shaped member 6. The clutch member 32 is so constructed that it may be moved into the neutral position shown in Figure 3 so that thc rotation of the shaft 3 is not transmitted to the bevel gear 29 or shaft 27.

Driving means corresponding to the pinion 21, gear 19 and ring gear 18 are provided for the rotatable gear supporting member 8 at the other end of the drum 4 so that said reel supporting members may be simultaneously rotated from the shaft 3 in either direction when the clutch 32 is thrown into mesh with the bevel gears 30 or 31.

The function of the reversing mechanism is to allow the reel supporting members 8 to be rotated in the reverse direction when occasion arises. For example, if the web had just been started around the reel in osition A" and a break occurred on the mac ine necessitating the removal of the material already on the reel, it would be simpler to reverse the reel supporting members until the reel was back in the position 13, where the reel is outof contact with the drum and the material on the reel could be removed, than to revolve the reel supporting members in the forward direction until the succeeding reel came into the position B.

It will be apparent that when the reel in position A has had sufiicient material wound thereon, it is only necessary to throw the clutch 32 into operative osition to rotate the reel supporting mem ers into position to discharge said full reel into supported position in the pockets 17 in the brackets 16, this rotation of the reel supporting members simultaneously aeting to ring the em ty reel from position B into position A w ere the cut-off end of the web 14 may be engaged therearound, the web 14 being severed while the empty reel and full reel are both in contact with the contact drum 4. As soon as the web is safely started winding upon the empty reel, said reel is slowly moved from position A to material receiving position A. During this movement of the reel from position A to position A, the path of the reel axis is increasingly eccentric with respect to the drum axis due to the constantly increasing diameter of the reel as the web is wound thereon. The major portion of the winding operation occurs while the reel is in position A. When the empty reel from the position B is brought into position A, the succeeding pair of projections 10 and 11 will be brought into position B to receive a new empty reel 13 to be supported in said position until the new reel in position ,A has had sufficient material wound thereon.

It will of course be apparent that the number of pairs of projecting members 10- 11 or the degree of spacing thereof may be varied as desired for accomplishing desired invention.

The apparatus of this invention is ap licable for reeling all kinds of paper an is particularly adapted for use in connection with paper making machinery, but it should be borne in mind, of course, that this apparatus may be used for winding any appropriate material.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles 0 this invention, and I. therefore do not pur ose limiting the patent anted hereon .ot era wise than necessitate by the prior art.

I claim as my invention:
