This invention relates to paper machines and has particular reference to the paper-reeling mechanism of a paper machine.

The main object of the invention is to provide means for facilitating the changing of reels on which the paper is wound, while maintaining the paper machine in full operation and with a minimum waste of paper as an incident to the changing operation.

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawings (two sheets) in which a preferred form of the invention is illustrated as applied to a so-called paper machine Pope reel.

In the drawings:

Fig. 1 is aside elevation;

Fig. 2 is a fragmentary section on the line 22 of Fig. 1, certain parts being omitted for the sake of clarity in illustration;

Fig. 3 is a section on the line 33 of Fig. 2; and

Fig. 4 is a section on a reduced scale on the line 4-4 of Fig. 1.

Referring now to the drawings, the main drum 6 is rotatably mounted in suitable bearings such as indicated at '7 on a main supporting frame or base 8. The base 8 also supports a main reel holder 9 which is pivoted to the base as indicated at 10 and which rotatably supports a main reel 11. The reel support 9 may be of conventional construction which includes a pair of arms such as indicated at 9, the upper or free ends of which are forked, as indicated at 12, to receive bearing blocks such as 29 in which the reel 11 is journalled. The paper web 14 passes over the drum 6 and is wound on the reel 11 in accordance with well known practice.

When the reel 11 is fully wound, it is extremely heavy and requires considerable time for removal from the reel holder 9, during which time it is objectionable, for obvious reasons, to stop the operation of the paper machine. Many devices have been developed for facilitating the Chang-- ing of reels, i. e., for facilitating the transfer of the web of paper from a full reel to an empty reel, but all of the devices, so far as known to us, are unsatisfactory, in that a large quantity of paper is necessarily wasted in effecting the transfer of the paper web from the full reel to th empty reel. The mechanism about to be described has been found to be highly efficient, especially in that it enables the web of paper to be transferred from a full reel to an empty reel with but a comparatively small amount or minimum of paper wastage.

Our improved mechanism includes an auxiliary or extra reel 15 and an auxiliary reel support which includes quadrant brackets 16 and 1'7 disposed on opposite sides of the web of paper and adjacent the opposite ends of the drum 6.

The quadrants 16 and 17 are pivotally mounted, as indicated at 18, on a bar connected with the supports 7 for the drum 6. The quadrants 16, and 17 are maintained in alignment with each other and in predetermined adjusted position relative to the drum 6 by means of pinion gears 20 which are secured to a transversely extending shaft 21 which is rotatably supported in suitable bearings carried by the frame 8 as clearly shown in the drawings. The pinions 20 are in mesh with gear segments 22 carried by the respective quadrants 16 and 17.

The quadrants16 and 17 are formed at their upper ends with journal box guideways such as 23 which receive squared journal blocks 24 in which the auxiliary reel 15 is journalled through the agency of its shaft ends 25.

On the inside of one of the quadrants, in this instance, the quadrant 16, a bell crank 26 is pivoted intermediate its ends as indicated at 2'7, one arm 28 of the bell crank projecting under the journal box 24 closely adjacent the inside 'faceof the quadrant. As shown in Figure 2, the

bell crank arm 28 may slightly overlap the adjacent enlargement or collar 29, one of which is carried by the shaft at each end toform journal boxes adapted to be received inthe forked ends of the main reel supports 9 and for maintaining the reel 15 properly centered between the respective journal boxes 24 and over the drum 6. The other arm 30 of the bell crank is'preferably considerably longer than the arm 28 and is operatively connected by suitable anti-friction means, such as indicated at 31, to a projecting portion 32 of a piston rod 33. The inner end of the piston rod 33 carries a suitable piston v34: which is fitted in a cylinder 35. The cylinder 35 is rigidly secured, as indicated at 36, to the inside facing of the quadrant 16. A suitable conduit 37, connected to a source of fluid supply and provided with suitable valve-controlling means, (not shown) communicates with the cylinder 35. When fluid pressure is admitted through the conduit 3'7 into the cylinder, it will be seen that the piston 34 will be forced outwardly, the bell crank 26 rocked on its pivot, and the end of the reel 15 which is engaged by the short bell crank arm 28 will be elevated relative to the drum 6. Likewise, when the fluid pressure is permitted to escape from the cylinder 35, the weight of the reel 15 will cause the same to lower itself and incidentally to return the piston 34 to its out position, as shown in full lines in Figure 3. The means for controlling the fluid pressure in the cylinder 35 may be of any desired form and, being well known in the art, need not be described in detail. Also, it will be understood that mechanical or electrical means may readily be substituted for the fluid-pressure means for actuating the bell crank 25 if desired.

The operation of transferring the web of paper from the reel 11 to the auxiliary reel 15 is, in substance, as follows: The paper web 14 is normally wound on the main reel 11 which is so arranged as to bear against the surface of the drum 6 over which the paper passes. The reel 11 is of course rotated at the same surface speed as the drum 6 merely by contacting with the surface of the drum 6 through the agency of the paper wound on the reel. During the time the paper is being wound on the main reel 11, the reel 15 is positioned in the auxiliary supports, one end of the reel 15 being held in elevated position, as indicated in dotted lines in Figure 4, by means of the bell crank mechanism 26, the other end-edge or under-surface portion being permitted to rest on the surface of the drum 6, as shown in said Figure 4. When the reel 15 is supported in this manner, it will be understood that the paper web 14 passes over the drum 6 without contacting with the surface of the reel 15, and that the reel 15 is caused to rotate at the same surface speed as the drum 6 without contacting with the paper. The rotation of the reel 15 is of course incident to its contact with the drum 6 at one end, as above mentioned. When the reel 11 is filled and itis desired to transfer the web of paper to the auxiliary reel 15, the web of paper is broken, by means of an air blast or otherwise, as is well known to those skilled in the art, between the reel 11 and thereel 15, and the web is blown upwardly into engagement with the reel 15 which has just previously been lowered so as to be in contact with the paper web-throughout its width. Inasmuch as the reel 15 is already rotating at the same surface speed as the drum 6,

it is obviously operative to take up the paperwinding function of the main reel 11 without delay and hence without causing the waste of a large amount of paper. When the paper web has thus been transferred to the reel 15, the full reel 11 is next removed from the main reel support 9, after which the auxiliary reel support may be swung on its pivots 18 by turning the shaft 21 to bring the collars 29 into position to be received in the jaws of the forked arms 9. As the paper builds up on the reel, which is now supported in the main reel support 9 and also in the auxiliary reel supports 16, 17, the main reel support 9 swings on its pivot 10 to move the reel and its journal boxes 24 out of the: guideways 23 in the auxiliary supports. When the boxes 24 are clear of the guideways, the auxiliary supports will be returned by the racks 22 and pinions 20 to their initial position for the reception of a fresh reel. The journal boxes 24 may be removed from the reel now being filled on the main reel support and used again on the fresh reel mounted on the auxiliary supports. By this means, the auxiliary reel 15 may be transferred to the main reel support, whereupon the auxiliary reel becomes the main reel and the journal box guideways 23 are free to receive another extra or auxiliary reel in preparation for a subsequent web-transferring operation.
