"WEB-RENEWING DEVICE.

Application filed. February 6, 1917. serial No. 147,427.

T 0 all whom it may concern Be it known that T, HENRY A. WISE lVooD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Web-Renewing Device, of which the following is a specification.

This invention relates to mechanisnr for connecting a fresh web to an expiring web in a printing press without stopping the press or slacking its speed.

The principal objects of the invention are to provide means actuated from the paper roll itself for controlling the connection of 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 provide improvements in the mechanism by which the operation is con trolled; and to provide an improved actuating cam supported by the web roll.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which--v Figure 1 is a side elevation of the end of a printing press showing a preferred embodiment of this invention applied thereto;

Fig. 2 is an elevation of the same looking from the front of the press, and showing the web roll broken away to illustrate the controlling arms; Fig. 3 is a slde vlew showing the position of the parts illustrated in Fig. 1 with parts in front omitted, or in other words, a section through the shafts just behind the frame and showing the wiring diagrannnatically; Fig. t is a similar view of the lower web roll on enlarged scale showing another position f the parts;

Fig. 5 is a front view of the parts shown in Fig. 4;

Fig. 6 is a perspective view of the actuating cam on the end of the web roll, and

Fig. 7 is a perspective view of the controlling cam for the surface of the web roll. This invention relates to that type of web renewing devices in which a fresh web roll is located in bearings on the press either above or below the expiring roll and is brought up to web speed by mechanism, not

, shown herein. Tnthattype of machine the expiring web is brought into pasting contact with the surface of the fresh web by a bodily moving pasting roller which engages the expiring web and moves it. One of these rollers is provided for each of the conditions that have to be met, namely, the application Patented net, at, rate,

of one expiring web to a new web roll above 1 and the application of the other expiring web to a roll below. I

The two pasting rollers are connected so as to move together in elther direction.

Vt hen either web is about exhausted both of these rollers are moved so that one of them comes into contact with the outside of the web and forces it into contact with the pasted fresh web roll. two rollers in one direction is for the purpose of using one of them, and the motion in the other direction for using the other. Tn either case the roller that is to be used is "brought close to the web and held there until the fresh web roll rot-ates into a position in which the pasted portion registers with a line along which the fresh web is to be pressed against it. Then connections are operated for releasing the pasting 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 described, brings the old web just in advance of the line on which it is to be severed into contact with the surface of the new web that hasbeen pasted or glued. It is secured to it by the pressure of the roller on the back of as that set forth in my prior applicationfor patent on web renewing device for printing presses filed September 19, 1914, Serial No. 862,469, and, is described herein because this invention is shown in the drawings as applied to a machine operating in that way.

Referring now to the drawings, the mechanism is shown as mounted on the frame 1 of a printing press, only the end of which is shown. In bearings on the brackets 2 with which this frame is provided a freshweb roll 3 is located, one for each deck of the press. This web roll is provided with a spindle 4 and an actuating cam 5 is located on-each end. In my above mentioned application this cam is fixed to the spindle, but in this case it is shown as having prongs 7 which enter the end of the roll between the layers of paper thereon. The cam therefore The motion of the.

is easily secured in any desired position. The expiring web roll is indicated at 6, and in these drawings it is the fresh upper web roll 3 that is being connected up with the expiring web from the lower roll although of course the opposite operation is also performed in the same way.

The following mechanism shown in my above mentioned applicationis also shown herein. Between each two decks of the press the shaft 11 is provided with a double toothed clutch 48 operated by a hand lever crank 29 fixed to a shaft 56. The oppositely facing teeth of this clutch coperate with teeth on a pairof bevel gears 46, both meshing with a bevel gear 47. This ear is supported by a shaft which is provided with a worm 45, which worm meshes with a worm wheel 44 on a shaft 40. On this shaft'is a bevel gear 41 which meshes with a corresponding bevel gear 42 on a vertical shaft 43. The shaft 40 and gears 41 and 42 are dulplicated above.

ach shaft 40 carries two gears 39 each meshing with an oscillating supporting member, in the form of a segment 36, one pair for each of the twoweb rolls. Each of these segments is pivoted on a stud 58 on the frame 1 and carries apivoted arm 37 in which the spindles of pasting rollers 38 are journaled. Thus it will be seen that the two parallel shafts 40 are caused to rotate simultaneously in either direction and the pasting rollers 38 moved up or down by manipulation of the hand lever crank 29. The pasting roller arms 37 are normally held against stops 49 ,on the segments 36 by means of springs 50 except while in pasting position. Vhn either pair of segments approaches the pasting position, adjustable pin stops 51 on the arms 37 come into contact with stop levers 52 pivoted to the frame of the machine at 53. Each stop lever 52 is held, by means to be described, in such position as to hold the arm 37 and compress the two springs 50. The latter are ready to propel the roller 38 against the fresh web roll when the two stop levers 52 are released from the position shown in Fig. 1 and thus apply the roller with spring pres sure against the web.

Both pairs of segments 36 are stopped in the correct pasting posit-ion 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 the shaft 56 of the hand lever crank 29. This throws out the clutch and sto 5 further motion in that direction.

11 the same stud 58 on which each segment '36 is pivoted. a toothed segment 57 is pivoted independently of the segment 36. The two segments 57 mesh with the teeth on opposite sides of a reciprocating rack bar 59. A spring 68 holds the.rack-bar 59 to the right, 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 that event the parts will assume the position indicated in dotted lines in Fig. 4. Each segment 57 is provided with a. recess 60 in one edge for receiving the end of the stop lever 52 and 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 segment 57 is pivoted a'trip lever 62 having a cam roller 63 thereon. This cam roller is adapted to be operated by the cam 5 on the end of the web roll spindle.

As so far described the operation is the same as in my above mentioned application. According to this invention a catch 67 holds the lever 62 in such position that the roller 63 is normally out of contact with this cam. In order to control the operation of these elements a cam 10 is mounted on the fresh web roll. This is shown as having athin. flange 10 adapted to fit the circumference of the web roll and it ,is shown as being mounted by slitting one of, or a few of, the top layers of the web roll and inserting the flange so that the cam appears on the web roll as a hump. It will be understood,-of course, that it can be inserted under the top few layers if desired or it can consist of a projection formed of any desired material, such as card-board, a pad of paper or the like, placed upon or beneath the outside layers of web roll. It is placed at a definite distance from the end thereof as will appear.

This cam is designed to operate a roll 14 located on a lever 12 which is mounted to swing freely on a shaft 13,carried by I the bracket 2. On this shaft 13 is also fixed an arm 16 which is provided with two electrical contacts 15 on opposite sides of the lever 12. On the arm 16 are two springs 17 pressing on opposite sides of the lever 12 and holding it normally in central position so as to keep the lever out of engagement with both of the contacts 15. This arm 16 is provided with two rollers 18, one

of which is adapted to engage the upper web roll when used in connection therewith and the other of which will engage the lower web roll when that is to be attached to the expiring web. The shaft 13 is provided with an operating arm 19 by which it can be turned into the several positions in which it is to be' used. Its normal position is shown in Fig. 1 and it can be swung from that either upwardly as shown in Fig. 3 or downwardly. In the present case it is shown as swung upwardly so that the righthand roller 18 engages the surface of the web roll and the roll 14 is in the path of the cam or hump 10.

@ne of the contacts 15 is connected with one end of an electro-magnet 20 for the upper roll, and the other with a similar electro-magnet for the lower roll. The other terminal of each of these electro-magnets is connected with the arm 12 so that when the arm 12 is moved backwardly from the position sliown in full lines in Fig. 3 it will connect up one of the electro-magnets 20, attract its armature 22 and release the catch 67. This releases the trip lever 62 and a weight 65 with which it is provided swings it over into the position shown in Fig. 4.

llt will be understood that, as in my application above referred tp, when this lever 62 is released from the cam 5 and allowed to move back into the position shown in Fig. 3 the spring 68 will force the segments 57 back to the right and force the stop-levers 52 up the inclines 61 until they are locked in the position shown in Fig. 3. The oscillating segments 36 are shown in Figs. 1 and 3 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. 3.

For the purpose of severing the web a thin knife 69 is controlled by a pin H on the top of the rack bar 59. The cutting action occurs as soon as the pin H moves back, preferably as described in my above mentioned case. i I

The operation of the features of this invention is as follows: When it is desired to attach the fresh web to the expiring one the arm 19 is thrown up so that one of the rollers 18 comes into contact with the fresh web roll above or below which has already been brought up toweb speed. This action brings the roller 1st into the path of the cam 10. At the proper time this cam causes the lever 12 to move away from. the paper roll surface and form an electrical contact between the lugs on the levers 12 and 16. This causes one magnet 20 to draw the catch 67 away from the lever The counterweight 65 on this lever causes it to drop and the roller 63 to come into contact with the cam 5. ltt will be understood that the weight holds the lever down in this position during the operation of this cam. This cam controls the operation of cutting by the knife 69 and pasting by one of the rollers 38. After the web is connected the lever 62 is swung back by hand until caught by the catch 67.

The other operations performed are conducted as in my above identified application preferably. The parts are operated auton'iatically and timed correctly in synchronism with the operation of the press, and the control of the actuation of the parts is provided from the web roll itself, so that there is no danger of their being operated independently of the web roll.

Although I have illustrated and described only a single form of the invention and shown it as applied to a particular machine, T am aware of the fact that the cam 10 can be used with the cam 5 shown in my above mentioned case, that the cam 5 shown herein can be used without the cam 10. and that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims, and that it can be applied in connection with other forms of web roll controlling devices.
