PAPER-ROLL MECHANISM FOR PRINTING-PRESSES.

Application filed March 27, 1913. Serial No. 886,4i'76.

United States, and residing at Chicago, in

the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in Paper-Roll Mechanism for forth in the claims.

Printing-Presses, of which the following is a specification, reference being had to the seen from the rear; Fig. 2 is a side elevation enlarged; Fig. 3 is an enlarged detail, being accompanying drawings.

()ur invention relates to mechanism for driving controlling and braking a paper roll, particularly 1 in printing presses in which the paper is pulled from the roll in the usual manner by the action of printing couples in an ordinary printing press.

It has for one of its objects the provision of new and improved means for disconnecting from the paper roll shaft the motor by j which the rotation of said shaft is con trolled.

It has for'another object theprovisionof whereby the .motor is disconnected by a stroke of a lever and the paper roll shaft is lifted out'of its bearings by a later part of the same stroke of said lever.

- It has for another object the provision" of means, preferably operated by the same lever, for centering the fresh roll of paper while on its supporting shaft in proper position relative to the press.

It has for another object the provision of means for shifting the roll of paper and the motor operatively connected thereto laterally relative to the press without dis- I turbing the connection of the motor with the paper roll shaft, for the purpose of compensating for any irregularity in the winding of the roll of paper, an ad ustment being made from time to time during the rotation of the press as may be necessary to keep the side margins of the printed page approximately of even width.

It is another object of this invention to improve devices of this general type in sundry details hereinafter pointed out.

fllhe means by which we have acc0mplished these objects are illustrated in the drawings and are hereinafter specifically described.

That which we believe to be new is set In the drawings, Figure 1- is an end view,

In the drawings, only a portion of the frame is indicated, in order to show one roll and its operating mechanism. It will, of course, be understood that the actual mechanism may contain'as many rolls as maybe desired and as may be convenient. 6 indicates shaft for thepaper roll 7,

The lower ends of the rods 46-47 engage suitable notches formed respectively in the shaft 39 and sleeve 36. It will be obvious that by pressing the handles of the bell-crank levers 5152 the rods 46-47 may be forced down- -ward, either both together or singly, into the notches on the sleeve 36 and shaft 39, whereby, by rocking the lever 45, either the sleeve 36 or the shaft 39, or both, may be given a partial rotation, for the purposes hereinafter set forth;

The gear 71 meshes with a rackbar 72 slidably mounted in a suitable support, as 74, on the frame 5.

' 75 indicates a bearing gage, which is It is obvious that by rotating the shaft 56 the shafts 60 and 69 will be rotated and by the engagement of gears 62 and 71 with the rackbars 63 and 72 the gages 66 and 75 may be moved toward or away from each other so as to bear against the ends of the roll, when they are brought together, to operate as means for the proper centering of the roll, Between the friction members 16 and 18 on the motor I connected with the hub 34 or the lower end of the lever 45-and the other of which is fixedly mounted on the shaft 56 by means of a collar 78. Said arms 78 are provided at their free ends with arc-shaped notches 79. The length of the arms 78 is the same as the distance from the center of the shaft 39 to the roll shaft 6. VVhent-he lever 45 is rocked downward, the arms 78 are carriedup and the notches 7 9 ultimately engage the shaft 60f the paper roll 7 so as to lift the same backward'out of its bearings, with what is left of the roll.

The operation of the above-described devices is as follows: When the parts are in the position shown in Fig. 1, the friction members 18 and 9 are in engagement. When the roll is started, if it is desired to rotate the roll shaft in such a way as to assist thereby the operation of leading the, paper from the roll "into the press, .the motor by any suitablearrangement is caused to runin the. same direction as that-in which it is desired tohave the roll run, and by the engagement of the friction members 9 and 18 the roll is caused to rotate with the motor. After the paper has been started through the press with the assistance of the motor, it is designed that the direction of rotation of the motor be reversed in any suitable manner so that the motor acts as a brake upon the roll of paper If it is desired to shift the paper roll longitudinally for the purpose of regulating the side margins, the roll, roll shaft and the motor are shifted tovgether so as not to change the tension of the springs 76by which the friction clutch members are held in engagement. To do this, one of the hand-wheels 26-27 is rotated, r0' tating the screw 19. This causes the movement in one direction or the other of arms 29-30, which, by their engagement with grooves 28-17, carry the friction clutch members 9 and 18 in the same direction together, thus moving both the roll, and rollshaft and the motor carriage, with the motor on it, together to the right or left without in any way changing the tension of the springs 76. This, of course, will, through the

gears

44, 42 and 41, rotate the shaft 39, but as long as

rods

46 and 47 are not in engagement with the notches, no other parts will be affected. The arm 37 and hub, 37 being feathered upon sleeve 36, will also move laterally on said sleeve. If it is desired at any time to free the roll from the press, either because the paper on it is exhausted or for any other reason, the lever 45 is forced backward and downward, the handle of the bell-crank lever 52 being gripped in so as to throw the rod 47 downward into engagement with the sleeve 36. As the lever 45 is swung back. the rotation of the sleeve 36 serves to free the arms 29-30 from engagement with the grooves on the friction clutch-member 9 and the disk 16. The handle of the bell-crank lever 51 is then to be pressed inward, throwing the rod 46 into engagement with the shaft 39, rotating the gear 44 through the medium of gears 41-42 so as to move the rack 13 and with it the motor 14 to the right in Fig. 1, freeing the friction clutch members 18 and 9 from en gagement. When these are free, the

rods

46 and 47 may be released and the further swinging of the lever 45 brings the socket 79 on the arms 78 into engagement with the rollshaft 6, lifting the same out of its bearings. When a new roll of paper is secured in position upon the shaft 6 and said shaft is brought into engagement with the lever mechanism 78, the weight of the roll of paper serves to rock the lever 45 upward, serving to rotate the shaft 56 and the gears 58-67, rotating-in turn the shafts 60-69 and the pinions 62-71, causing the gages 66-75 to move toward each other. At the proper moment, the lever 45 is grasped for completing the stroke, bringing the gages 66-75 into contact with the ends of the paper roll and centering said roll laterally relatively to the press, At the proper moment, the rod 46 is brought into engage ment with the notch on the shaft 39,- moving the motor 14 again into operative engagement with the shaft 6. At the proper time later in the stroke of the lever 45, as just described, the rod 47 is brought into engagement with its notch on the sleeve 36, serving to swing the arms 29-30 again into engage ment with the grooves 28-17. The parts are so proportioned that the gages 6675 complete the centering of the roll of paper 100 just as the arms 29-30 are brought into operative engagement with the grooves 28-17. The levers 51-52 are then released,

permitting the rods 46-47 to pass out of engagement with the shaft 39 and the sleeve 105 36, respectively, and the lever 45 is then moved slightly to the left in Figs. 2 and 3,

to free the gages 66-7 5 from the ends of the roll of paper. v I f That which we claim as our invention, 11% and desire to secure by Letters Patent, is-
