Patented June 28, 1932 UNITED STATES PATENT OFFICE HARRY M. ROSS, F INDIANAPOLIS, INDIANA, ASSIGNOR 0F ONE-HALF TO BEVERIDGE PAPER COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION AUXILIARY REEL FOR PAPER MAKING MACHINES Application filed June 23,

This invention relates to an auxiliary paper reel for use in connection with a paper making machine whereby the continuous sheet coming from the paper making machine may be interrupted by causingit to be rolled on said auxiliary reel.

In the manufacture of paper, the paper sheet is fed continuously to the cutting rolls and knives which trim and cut the paper to the proper size. This is occasioned particularly wherein it is desired to pack the paper in flat sheets as distinguished from packing it in rolls. In the former instance, as the paper continuously comes from the paper making machine it passes through cutting wheels which cut it longitudinally to the desired width, whereupon it passes through knives which cut it cross-ways to the proper length. A crew of operators receive the cut and trimmed sheets, stack them and remove them from the receiving end of the machine when a predetermined number has been fed onto the pile. Said operators also eliminate mutilated or damaged sheets as they come 5 from the machine.

Inasmuch as the feeding of the paper from the paper making sheet is continuous, and it becomes necessary at times to relieve the crew of operators, adjust the cutting knives or for any other purpose interrupt the continuous feeding of the roll, it is customary for this purpose to shunt the paper onto an auxiliary reel so that it will be rolled thereon until the operators are again ready to receive it from the machine. Thereupon, it is necessary that the paper coming from the machine be received, as well as the paper that has been rolled on the auxiliary reel, thus making two thicknesses of paper passing through the cutting wheels and knives. In thus receiving the double sheet, that coming from the auxiliary reel is necessarily upside down so that the top surface of the paper coming from the machine becomes the bottom surface of the paper coming from the anxiliary reel. VVherein there is a difference in color or finish between the top and bottom surfaces, it becomes necessary to separate the sheets coming from the auxiliary reel from those com- 5o, ing from the machine which is expensive and 1930. Serial No. 462,964.

impractical, or otherwise the printers receivma be disen a ed from one end thereof oerinitting an operator to swing the reel to reversed position upon the turntable and clamp it to cause the paper to be fed therefrom right side up.

The full nature of the invention will be understood from the accompanying drawings and the following description and claim:

Fig. 1 is a front elevation of the auxiliary reel mounted upon the turntable. Fig. 2 is a plan view thereof. Fig. 3 is a view taken on the line 33 of Fig. 2. Fig. 4 is a diagrammatical illustration of the paper being rolled upon the reel. Fig. 5 is a diagrammatical illustration of the paper being unrolled therefrom.

In the drawings there is shown a supporting frame which is a part of the paper making machine, said frame being positioned immediately in front of the rolls which feed the paper to the cutting wheels and knives. Supported on each end of the frame, there is a pair of rollers 11 which support the opposite ends of the cross bar 12 when the reel is in operative position. Mounted on the bar 12 there are bearing supports 13 in which is mounted the shaft 14 of the-reel.

The reel comprises a plurality of radially extending spiders 15 secured to the shaft 14. Mounted on the spiders there are longitudinal slats 1.6 comprising the usual skeleton frame of the reel about which the paper is adapted to be rolled.

On each end of the shaft, and keyed thereto externally of the bearing supports 13, there are brake drums 17 having brake shoes 18 mounted thereabout, which are contracted by the brake wheels 19. Supporting the cross bar 12 intermediate the ends thereof and mounted upon the framework 10 there is a turntable comprising the annular lower support and ball race 20 and the upper annular ball race 21, between which there is a plurality of ball bearings 22. At each end of the cross bar 12 there is a locking member 23 for locking said cross bar and reel with the frame 10 when in horizontal or operatve position. On one end of the frame 10 there is a bearing sup port 24 carrying the stub shaft 25 on which the driving pulley 26 is mounted.

Slidably keyed to said stub shaft 25 there is a clutch 27 adapted to engage with the corresponding clutch member 28 on the shaft 14. The clutch lever 29 is mounted upon the support 24 in a position to slide the clutch 27 in and out of engagement .with the clutch member 28, the latter being mounted on each end of the shaft so as to interlock with the clutch 27 when either end is brought into engageable position.

As diagrammatically illustrated in Figs. 4 and 5, the paper passes from the last roll 36 of the paper making machine, and ordinarily is carried therefrom into the cutting and trimming mechanism of the machine not shown. When it is desired to interrupt the cutting operation without interrupting the feeding of the paper, the paper is cut diagonally in the usual manner and started about the auxiliary reel. As shown in Fig. 4, the paper is being received upon the auxiliary reel with the top of the paper illustrated in full lines and indicated by the numeral 31, while the bottom of the paper is illustrated by dotted lines indicated by the numeral 32. The paper takes the direction indicated by the arrow so that the top of the paper is toward the inside of the reel and the bottom of the paper is toward the outside.

It will be noted that wherein the reel remains in its original position, upon unrolling the paper it would come from the top of the reel with the bottom side 32 up and the top side 31 down, or in inverted position which is undesirable. After the interruption and when it is desired to again feed the paper through the cutting mechanism, the paper is again diagonally cut and the free end by-passed under the reel directly to the cutting mechanism. Thereupon, the clutch 27 and locking members 23 are disengaged so that the reel with the full weight of the paper carried thereby may be readily swung to its opposite position upon the turntable. Thereupon, it is locked in fixed position by the looking members 23 with .the paper unrolling therefrom in the direct-ion of the arrow as shown in Fig. 5. By thus reversing the position of the reel, the paper is brought therefrom top-side up from the. bottom of the reel as distinguished from the bottom-side up from the top of the reel. Thus, the paper is carried from the bottom of the reel directly to the cutting mechanism to be cut and handled simultaneously with the paper coming direct from the paper making machine and with the same side of the paper uppermost. The brake shoes 18 through the medium of the brake wheels 19 are then applied so as to slightly retard the unrolling action and give the proper tension to the paper passing therefrom. After the paper has been unrolled from the reel, it may then remain idle until it is again desired to interrupt the passage of paperto the cutting mechanism whereupon the reel may be operated in its reversed position until the paper has been rolled thereon, after which it is again reversed for unrolling.

The invention claimed is:

The process of interrupting the continuous passage of paper from a paper making machine to the paper cutting mechanism associated therewith consisting in directing the paper from the machine to an auxiliary reel, winding the paper upon said reel until it is desired to end the interruption, thereafter shunting the paper past said reel directly to the cutting mechanism, turning said reel end for end in the same horizontal plane in which the paper is wound and feeding the paper from the reversed reel while in the same plane to the cutting mechanism simultaneously with the paper shunted thereby.

In witness whereof, I have hereunto affixed my signature.

HARRY M. ROSS.
