T 0 all whom it may concern:
Be it known that I, HENRY A. WISE Woon,
.a citizen of the United States, residing at ,automatically connecting the end of the fresh web with the end of the expiring one and severing the latter from the stub while the press is operating at full speed; to obviate the necessity of moving the fresh web roll bodily after it is put in position on the press, and the necessity of threading the fresh web into place by hand; to provide an arrangement whereby the old stub can be removed and the fresh web roll put in position at any convenient time, independently of each other; and to provide other improvements in details of construction and combinations of parts as will appear hereinafter,
Reference is to be had to'the accompany- I ing drawings, in which Figure 1 is a side elevation of the end of a printing press showing a preferred embodiment of this invention applied thereto;

Fig. 11 is a similar view showing the upper pasting roller in contact with the fresh web roll and also showing in dotted lines the position of the pasting rollers when the upper web roll is being renewed; and
- Fig. 12 is a similar view showing the last step in the operation.
In the ordinary forms of web printing presses now employed for printing news papers or similar products, the web roll is usually mounted in bearings on the side frames of the press and is provided with suitable tension devices for preserving the proper tension of the web while the same is being drawn into the press. When the web roll is nearly exhausted it is the ordinary practice to stop the press in order to permit the expiring web to be severed, to remove the stub of the old roll, from its bearings in the side frames, then to mount'a fresh web roll in the bearings, and finally to paste the end of the fresh web to the end of the expiring web so as to permit the fresh web to be drawn through the machine. Although several device's have been invented for performing these functions automatically, they are ordinarily performed by hand in newspaper plants so far as I am aware, and considerable time is consumed in accomplishing the transfer of the web rolls. Under present conditions this time is valuable and it is important to save it.
This invention is made for the purpose of providing a practical means for accomplishing these operations automatically. Briefly stated, the operations are carried out in the following way in accordance with this in-.
vention. One web rollis mounted directly i the old web'is brought into pasting contact with it and is pasted to it. The web from the exhausted stub is severed at the same time and the stub is removed. Then, of course, a fresh web roll is substituted for the exhausted stub and when the lower web is nearly exhausted the same operation is performed.
For the purpose of speeding up the fresh web roll to web speed, a number of driven propellers are provided, operated by a nonpositive connection, so that it can slip when the propellers are first applied to the sur- 'face of the web roll and gradually bring it up to web speed. The expiring webs are brought into pasting contact with the sur face of the fresh webrolls by two rollers. These rollers are connected so as to rotate simultaneously in either direction and when one web is about exhausted these rollers are moved so that one of them comes into contact with the outside of that web and forces it into contact with the fresh web roll. The motion of the two rollers in one direction is for the purpose of using one of them and the motionin the other direction for using the other. This roll in either case is brought close to the web and held there until the web roll rotates into a position in which the pasted portion registers with the line along which the fresh web is to be pressed against it. Then means controlled by the web roll shaft operates connections for releasing the roller from this position and causing it to press the expiring web against the fresh web roll. This, of course, in View of the timing just specified, brings the region on the old web just in advance of the line on which it is to be severed into 'contactwith the surfaces of the new web that have been pasted or glued and it is secured to it by the pressure of the roll thereon. The severinn of the old web is then performed auto matically.
Referring now to the drawings it is to be observed that the mechanism is mounted on the frame 1 of the printing press only the end of which is shown. In hearings on the brackets 2 with which this frame is provided a fresh web roll 3 is located for each deck of the press. This web roll is provided with a spindle having a cam 5 on each end. The expiring web roll is indicated at 6 and as shown in Figs. 1 to 7 it is the fresh upper roll that is being connected upuwith the expiring web from the lower r0 Referring to Fig. 8 it will beseen that the earn 5 is provided with a hole into which a pin 7 can drop. This pin projects from a templet 8 which is provided with a frame 9 having a scalloped. edge. Before the web is appliedthis templet is placed on the roll with the pin 7 in the hole of the cam and consequently with the scallops at a certain definite position on the circumference of the roll. The free end of the web is torn off along the scalloped edges to provide. a correspondingly shaped edge on the weli itself. This operation is performed twice, once from each end. The points a. of these scallops (Fig. are loosely asted or fastened to the surface of thewe roll in order to prevent them from getting loose and unwinding the web during its rotation. The outer edges 6 are covered with suitable paste or glue ready to be attached to the expiring web. Spaces careleft unpasted in order to provide paths for the web roll propellers. It will be noted that the highest portion of the cam 5 is located just in advance of the scribed hereinafter in time to leave the scalloped edge in proper pasting position.
The web renewing mechanism is operated from a shaft 11 mounted in suitable bearings on the frame and driven from the press by means not herein shown. For the purpose of propelling the fresh web roll the following mechanism isshown. A friction disk 12 is driven by friction rollers 13 on hubs of miter gears 1%. These miter gears are supported on studs in a bracket 15 and driven through gears 16 "on the shaft 11. There are two sets of these parts for each deck of the press one'above and one below the two web rolls. The friction disk 12 is slidably fastened to a shaft 17 by a loose key and keyway and this shaft is journaled in the bracket 15 and also in a bracket 18.
The back pressure of the disk 12 is taken up by means of an anti-friction bearing 19.
Nuts 20 on the hub of the bracket 15 furnish means for taking up the Wear of the parts.
'to.- Two gears 31 and 32 secured to the ends of the shafts 28 and 29 mesh with the gears 22 and 24 respectively and are driven from the gear 21 with which they both mesh, although they are not in the same plane. On the outer ends of the shafts 23 and 25 are fastened operating levers 33 and 34. By means of these the shafts can be turned on their own axes and their arms 26 and 27 a 3 thus moved to bring the propellers 30 into contact with the surface of the fresh web roll. This causes the fresh web roll to rotate with its shaft in the bearings on the I brackets 2. This-rotation will be very slow at first on account of the slipping of the. friction disk 12. but the speed will gradually increase until the circumference of the fresh web roll rotates at the speed of the provided for the purpose of web, the connection being designed to produce this as the maximum speed. It will be understood, of course, that each of the levers 33 and 34 operates one set of propellers, and that in-Fig. 1 the lever 34, shown at the top of the sheet, is the one operated for he purpose of rotating the fresh web roll 3.
Between each two decks of the press the shaft 11 is provided with a double toothed clutch 48 operated by a hand lever crank 49 fixed to a shaft 56. The oppositely facing teeth of this clutch coiiperate with teeth on a air of bevel gears 46, both meshing with a evel gear 47. These gears are supported in suitable bearings by shafts which are provided with worms 45, which worms mesh with worm wheels 44 on a pair of shafts 40. On these shafts are bevel gears 41 which mesh with corresponding bevel gears 42 on a vertical shaft 43 suitably supported in brackets on the frame. This arrangement is turning two pairs of oscillating supporting members, in
the shaft This throws out the clutch and stops further the form of segments 36, one for each of the two web rolls. Each of these segments is pivoted on a stud 58 on the frame 1 and carries an arm 37 in which the spindles of pasting rollers 38 are journaled. Each segment meshes with a gear 39 on one of the shafts 40. Thus it will be seen that the two parallel shafts 40 at each side of the press are caused to rotate simultaneously in either direction and the pasting rollers 38 moved up or down y manipulation of the hand lever crank 49. The pasting roller arms 37 are normally held against stops 49 on-t-he segments 36 by means of springs 50'except while in pasting positions. When either pair of segments approaches the pasting position, adjustable pin stops 51 on the arm 37 come into contact with cam levers 52 pivoted to the frame of the machine at 53. V ach cam lever 52 is held, by means to be described, in such position as to holdthe arm 37 back and compress the spring 50. The latter is ready to propel the roller 38 against the the cam lever 52 is released shown in Fig. 1 and thus with spring pressure.
Both pairs of segments 36 are stopped in the correct pasting position by means of two pins 54 on one of the segments coming into contact, at the end of the motion of that segment, with a throw-out lever 55 attached to 56 of the hand lever crank 49.
from the position apply the roller motion in that direction. On the same stud 58 on which each segment 36 is pivoted, a toothed segment 57 is pivoted independently of the segments 36. The two segments 57 mesh'with the teeth on opposite sides of a reciprocating rack bar 59. Each segment 57 is provided with a recess 60 in one edge for receiving the end of the cam lever 52 and fresh web roll when holding it in the position shown in Fig. 1. 'It also has a cam incline 61 down which the end of the lever 52' is adapted to slide when the segment 57 is drawn back to release the cam lever.
To the opposite end 64 of each is pivoted a trip lever 62 having a cam roller 63 thereon. This cam roller is adapted to operate on the cam 5 on the end of the web roll spindle. A spring 67 holds the lever 62 in such position that the roller 63 is normally out of contact with this cam. A spring 68 holds the rack bar 59 to the right in Figs. 1, 5 and 6, thus drawing the two segments 57 in the same direction and keeping the ends of the two cam levers 52 in the recesses 60, unless the segments 57 are forced to the left positively. In this event the parts will speedlly assume the position indicated in dotted lines in Fig. 6.
It will be understood, of course, that when this lever 62 is released from the cam and alsegment 57 lowed to move back to the position shown in i Fig. 5, the spring 68will force th segments 57 back to the right and force the cam levers 52 up the incline 61 until they are locked in the position shown in Fig. 5.
These parts above described that are shown inside the frame are duplicated on the two sides of the frame. It will be understood that the oscillating segments 36 are shown in Figs. 1 and 5 at one end of their oscillation. When they move back to the opposite limit of their motion they assume the position shown in dotted lines in Fig. 5.
For the purpose of severing the web, a thin knife 69 is securely stretched between two crank levers 70 by means of tie rods 71 and a turn buckle 72. One end-of the knife 69 is elongated into a hook handle 73 adapted to bear against a pin 74 on the top of the rack bar 59. A pair of springs 75 connected with the crank levers 70 tend to turn these levers in such direction as to sweep the knife 69 acrossthe expiring web to sever it. This operation occurs as soon as the pin 74 moves can be operated by hand to draw it back to the position shown in Fig. 4, of course after the rack bar 59 has tion.
The operation of the device is shown diagrammatically in the last four figures. The fresh paper roll 3, prepared as described, is placed in position in the printing press with its shaft in its bearings, and the propellers 30 are brought into contact with its surface to cause it to revolve at web speed as has been explained. This position of the parts 18 shown in Fig. 9, it being understood that here the lower web roll is the fresh one instead of the upper one as shown in Fig. 1. The expiring web from the roll 6 is then brought into pasting position with respect returned to normal posito the fresh web roll by throwing the clutch 4:8 into connection with the proper clutch teeth. This causes the four segments 36 with their two pasting rollers 38 to revolve in the desired direction. They are auto.- matically stopped in their proper position by one pin 54 and throw-out lever 55 as previously described. During most of this motion the springs 50 tend to force this pasting 5 on the paper roll spindle as shown more fully in Fig. 6; In this position the cam will exert a direct thrust on the end 64 of the segment 57 This positively forces the segment to the left and the rack bar with it, but
its function at this time is to release the cam lever 52. This then moves out of the way, of the stop pin 51 and allows the springs 50 to force the pasting roller yieldingly against the expiring web and fresh web roll. It is to be observed that no matter which web roll is to be supplied all the segments and cam levers are operated on account of their connection through the rack bar. Although in theory either one of the levers 62 may be operated for the purpose of controlling the movements of the. segments 57 and the cam levers 52, yet it is necessarily the roll which is adapted to contact with the cam 5 on the fresh web roll spindle that is operated in order that these parts may be timed correctly. The other lever 62 at this time is operated by the movement of the other segment 57 but without accomplishing any function.
The roller 38, which up to this time has been held by the segment 36 in the position shown in Fig. 9, now moves toward the fresh web roll, and the other pasting roller moves around. out of the way, as shown in Fig. 10. The upper roll in this case thus engages the upper web and forces it down on the fresh web roll as shown in full lines in Fig. 11, being forced into this position by the springs 50. On account of the control of this motion from the cam 5 it necessarily engages the new roll at a-point-just in ad-' Vance of the line of pasted scallops thereon, so that it presses the old web into contact with the paste and pastes the two together.
The completion of the rotation of the cam 5 to its highest point causes the rack bar 59 and the knife stop pin 74 to move forward sufliciently to release the web severing knife 69. and completely severs it as shown in Fig. 12. The dotted lines'in Fig.'1l indicate the position of the webs and rollers when the fresh web roll is above instead of below. A
This sweeps across the expiring web memes single knife is used for severing both webs. It is, to be noted that the web from either source of supply is drawn off through a common pathway by means of the usual directing and. guiding rolls 80. This is possible because the web rolls are caused 'to' rotate in opposite directions, so that their adjacent surfaces move in the same direction and the pathway extends from a point between them.
In this way it will be seen that the parts are operated automatically and timed absolutely correctly from the shaft 11 which is operated by the press, and by means of mechanism which is not complicated or likely to get out of order in practice.- Furthermore, no mechanism is required for transferring the fresh Web roll from one position to another, no threading of the new web into position is necessary, and the fresh roll can be placed in position at any time after the exhausted stub is removed, which need not be done immediately after the connection of the two webs.
