ATTORN EY Patented Mar. 19, 1940 UNITED STATES PATENT OFFICE FASTER- FOR NEWSPAPER PRESSES I Eugene P. Doyle and Leo F. Long, Toledo, Ohio Application February2, 1938, Serial No. 188,216 7 8 Claims. (01. 2422-43) This invention relates to pasters for newspaper presses in which a continuous webof paper is drawn from a roll by the press and, substantially when the roll is exhausted, a web from a new or .5 fresh roll is adhesively connected to the web from the previous roll so that an uninterrupted web of A further object is to produce a simple and efficient timing device for pasters of the above character in which the adhesive strip on the paper roll which is rotating at press speed, first engages the traveling paper web when the roll advances into contact with the web.-

A still further object is to provide a drive for the reel with a member inserted between. the convolutions of the paper roll which is instrumental in rendering the drive effective.

Other objects and advantages of the invention will hereinafter appear and for purposes of illustration but not of limitation, an embodimentoi the invention is shown on the accompanying drawings in which Figure 1 is an end elevation of the reel for the paper rolls showing particularly the roll driving means and switch for operating the reel motor;

comprises a reel it which is mounted for rotating movements on a suitable standard H. The reel in this instance has three arms a, b, and c, the arms b and c in this instance supporting fresh rolls i2 and i3 respectively of paper or dinarily used for newspapers and the arm a. supporting a substantially exhausted roll M of paper. The web :5 leading from the roll l4 extends upwardly to a' relatively soft guide roll i5a and from thence passes in a suitable manner to the newspaper press (not shown), the fresh roll 12 being substantially in the position prior to splicing or adhesively connecting the end of the roll 2 to the web l5, it being understood that substantially upon effecting the paster. the reel H) is rotated ina clockwise direction (Figure 1) so that the roll l2 will be in the position shown by the roll I A on the drawings, such movement being efiected by an electric motor l6 having a Worm and wheel connection I! with the reel.

Before the paster or splicing is accomplished, the next succeeding or oncoming roll of paper, such as the roll !2, is rotated to bring it to approximately the speed of the newspaper press with which the device is associated. The roll I2 is brought up topress speed by a wheel I8 having a covering l9 of rubber or some similar material. The wheel i8 is carried by an arm 20 and driven from a bevel gear 2! operated'by a flexible drive 22 from the newspaper press and in such manner that when the wheel 18 is in contact with an end of the paper roll 12, .it will bring the latter up approximately to press speed or at the rate of speed that the web l5 travels in the normal operation of the press.

The arm 28 is pivoted on a shaft 23 and a bent arm 24 is connected to the outer end of the arm 2!! by a bolt 25 which slides in one of the arms, a coil spring 25 being interposed between these arms. The wheel i8 is moved into engagement with the end of the roll l2 adjacent the peripheral surface thereof substantially as shown and at this time the roll i2 is spaced a short distance from the guide roll 65a. It will be obvious that in this manner the roll 52 is very quickly rotated so that the web thereof isv moving at approximately the traveling speed of the web 15 in the normal operation of the press.

The web from the roll 12 is connected to, the v web l5 by adhesive applied to the end of the fresh roll and preferably adhesive is applied as indicated at 21 on Figure -6, the zig zag line affording more secure adhesive connection with the web I 5. It is desirable that as soon as theroll I2 is brought up to press speed that it be advanced so that the adhesive 21 can engage the web l5 so as to allow the newspaper press to continue uninterruptedly. For that purpose, the reel motor IE is energized substantially when the new roll I2 attains press speed. This is accomplished in an exceedingly simple manner as will now appeal. A timing strip 28 preferably of some material like Celluloid and of a size and shape simulating a banjo pick, having, as indicated, a substantially pointed end, is inserted between the convolutions of the roll I2 adjacent the peripheral end portion and substantially in alignment with the adhesive strip 21.

For convenience of the operator, the fresh or oncoming roll is usually allowed to come to rest and in its balanced condition, the line of adhesive 2! is applied and then the timing piece 28 is inserted in such manner that a portion thereof projects beyond the end of the roll and a substantial portion is disposed between the convolutions of the roll. It should be understood that the line of adhesive 21 can be applied any place along the roll although from the standpoint of convenience, the operator will usually permit the roll first to come to rest. The timing piece 28 should project far enough beyond the end of the roll to contact a timing switch arm 29 which is pivoted in a housing 30 and in its normal position hangs downwardly substantially as shown on Figure 4.

The inner end of the arm 29 carried a contact strip 30a engageable with a contact strip 3| which acts as a stop, the outer end riding along a strip 32 which frictionally engages and holds the strip 30a in normal position. The contacts lead from the strips 30a and 3| to a solenoid 59 controlling the operation of the reel motor I6 and the arrangement is such that when the arm 29 is swung outwardly or to the position shown in Figure 5 in which the contact is broken, the solenoid operates in such manner when the paster control button is depressed as to energize the motor I6 until the paster control button is released, to advance the reel in a clockwise direction (Figure 4) moving the roll I2 to the position of the roll I4 shown on Figure 1, thus bringing the line of adhesive 21 into contact with the web I5 at the proper time and splicing these webs together. The swinging of the timing switch arm 29 to break the contact is caused by the timing piece 28 which moves into contact with the free end of the arm as the roll I2 rotates and then passes under it allowing the arm 29 to swing back by gravity to its normal position. The timing piece 28 remains in place until the roll has been unwound to free it when it is thrown or drops from the roll.

Reference is hereby made to our co-pending application, Serial No. 167.100 for the details of operation of the driving wheel I8 and the web severing means by which the web I5 is out between the exhausted roll I 4 and the roll I2 substantially at the time when the pester or splicing of the webs is accomplished. The severing of the web from the exhausted roll can be accomplished in accordance with the disclosure in the co-pending application whereby the pastel can be effected without interrupting the normal operation of the press. Details of construction and operation of these parts form no part of the present invention so that additional description and illustration is not considered necessary.

The arrangement is such that when the driving wheel I8 is in operative driving relation to the paper roll, the switch mechanism is away from the roll and conversely, when the switch mechanism is in operative position, the driving wheel I8 is disposed in inoperative position. For this purpose the switch housing is carried by a bracket arm 33 which is pivoted at to a portion of the bent arm 24. The arm 33 is connected by a link 35 to an extension 36 of the wheel carrying arm 20. An inspection of Figure 2 will show that when the parts are in the full line position, the wheel I 8 is away from the paper roll but the switch mechanism is disposed close to the end of the roll in position to be engaged by the actuator or timing piece 28. On the other hand, when the parts are in the dotted line position, the wheel I8 is in operative driving relation to the paper roll but the switch mechanism is swung away from the roll to inoperative position.

From the above description, it will be apparent that the sequence of operations is as follows: adhesive is applied in any position selected by operator on the next succeeding roll of paper or the roll which is to be applied or connected to the traveling paper web preferably in the manner shown in Figure 6. Then the timing or Celluloid piece 28 is inserted near the periphery of the roll and between the convolutions thereof substantially in line with the adhesive strip. When the operator considers that it is time to make a pastel, the driving wheel I8 which is constantly rotating at approximately press speed is moved into engagement with the end of the roll thus driving the roll at press speed. As more fully described in our co-pending application hereinbefore mentioned, movement of the driving wheel I8 to roll driving position is effected manually. as diagrammatically shown on Figure 8, by a handle 40 which is fixed to a shaft M. The

shaft 4! is suitably connected to rock an eccentric disc 42 which is free to swing about its axis 43. Turning movement of the shaft 4| swings an arm 44 which has a notched end 45, so that the latter engages a pin 46 on the disc 42 and rocks the disc in a counterclockwise direction to the position shown on Figure 8. When the eccentric disc 42 is in its raised position, the pin 46 is engaged by one end of a latch arm 41 which holds the same in place. As soon as the eccentric disc is engaged or latched by the arm 41. the handle 40 is released and the arm 44 drops downwardly to its normal position. As shown the arm 41 is pivoted between its ends and the opposite end carries the armature of a solenoid 48. end which engages the eccentric disc 42 so that when the disc is raised as above described, the bent arm 24 is likewise rocked to move the driving roll I8 to driving position into engagement with the paper roll. By depressing the pastor button, which is indicated as 58 in Figure 8 the driving wheel I8 is swung, as set forth in our copending application, away from the paper roll. By referring to Figure 8, it will be apparent that by depression of the paster control button or switch 50, the solenoid 4-8 is energized through the leads 5|, 52, 53 and 54, thereby rocking the latch 4'! in a counterclockwise direction and releasing the eccentric disc 42. The disc 42 will then swing downwardly (counterclockwise) thus allowing the driving wheel I8 to swing by gravity away from the paper roll and to such position that the contact piece 55 on the bent arm 24 bridges the spaced contacts 56. Thereupon the switch mechanism, and particularly the timing The bent arm 24 has a roller 49 at one switch arm- 29, is moved into the path of revolving movement of the Celluloid piece 28 which strikes against the arm 28 breaking the contact as; above mentioned and thus; through suitable means, the reel motor operates at the proper time to move the line of adhesive into contact with the traveling web i5. The tail of the web is then severed in any suitable manner and the poster is completed, when the roll i2 is in the position occupied by the roll- M (Figure l) and the pastel button is released.

When the operator sees that the roll is substantially exhausted and shortly before web splicing is required, the driving wheel i8 is moved manually into engagement with the paper roll to bring it to press speed, as above indicated and as particularly shown and described in our copending application. It is to be understood that upon actuating the handle M! to bring the driving wheel 58 into operative position, a switch 5'! is thereby closed to allow current to flow through lead 58 to a solenoid 59 and thence through lead 60, switch arm 29, contact strip 3! and lead 54. Energizing of solenoid 59 moves the armature 5i upwardly opening switch 62 and closing switch 53. As soon as the handle All is released, the switch 5'! is opened and current is then supplied to the solenoid 55 through leads 5! and (i l, switch 53, lead 65 and then through the solenoid 59, lead 6! and other connections above mentioned. The operator then presses the control or paster button 56, whereupon the driving wheel I8 is released and the timing switch is moved into operative position as above described. When the switch arm 29 has been thrown outwardly, as indicated in Figure 5, so that the solenoid 59 is released, the reel motor it will revolve the paper rolls at the proper time until the operator releases the paster button when the pester is completed. In this connection, it will be apparent that upon closing the switch or paster control 50, current passes to the reel motor Hi through the leads 5!, 52 and 65 through switch 62 (which has been moved to its dotted line or closed position upon release of the solenoid 59), and then through lead 6'! to the reel. From the reel motor 16 current flows through lead 68, contacts 56 and contact piece 55, lead 69 and lead 54. Obviously, in absence of an automatic tail severing device, the speed of the press must be reduced to afiord the operator sufficient time to sever the tail by hand but the use of an automatic tail severing device as shown in our co-pending application will enable the paster to be accomplished without reduction in press speed.

One advantage of the above pastor is that an unskilled person can apply the adhesive to the paper roll and insert the timer piece. This is a decided improvement on similar devices which require that the adhesive be applied at a certain place and ordinarily requiring the services of two men, one to hold the roll and the other to apply the adhesive.

It is to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as define in the appended claims.
