This invention relates to devices for deliv-' ering paper to printing presses and has for its ob ect to provide a new and improved device of this description.

The invention has as a further object to provide a device for delivering paper to printing presses which-gives a com lete and full control of the paper on'the'rol while it is being delivered to the press. 4

The invention has as a further object toprovide-a device for delivering paper to printing presses which will prevent the paper from running off of the roll when the press is slackened or stopped.

The invention has further objects which are more particularly pointed out in the ac-. oompanying description.

Referring now to the drawings, Fi 1 is an end view ,of one form of device em odying the invention. 7

Fig. 2 is a view similar toFig. 1 showing the paper which is delivered to the press as running in the opposite direction to that shown 1n Fig. 1.

Referring now to the drawings, I have illustrated a movable support for aplurality of rolls of paper with a series of endless belts arranged to engage one of the rolls.

For purposes of illustration the roll supporting device is' shown as a shaft 1 having arms 2 and 3 thereon, the shaft 1 being rotatably mounted upon supports 4 and 5. Some means is provided for rotating the shaft 1 and the arm 3. As herein shown this is accomplished by means of a worm ear 6 con nected with the shaft 1, said gear eing actuated by a worm 7 operated by a motor 8."

parts through 12, 12a, 12b and 120;

-15, 16, 17, and 18.

rolls of paper 9, 10,and 11. Associated with the roll support are a series of endless belts These belts pass over d irection changing devices 13, 14, All of the direction changing devices are fixed in position except the direction changing device 15 which is movable so as to keep the belt taut and thus keep it in proper relation to the roll of paper at all times, as the roll gets smaller as the paper is unwound therefrom.

These direction changing devices are prefa series of keep the belt taut and this means also moves erably pulleys or rotatable devices of any J the direction changing device 15 as the roll from which paper is being driven to the ress decreases in diameter so asto keep the elts' at all times in proper position with relation to the roll of paper.

In the construction shown this is accomplished by connecting with each direction changing device 15 a weight 20. This weight is adjustably mounted on an arm 21 and is held in any adjusted position by a set screw 22.. Each arm is pivoted between its ends to a fixed part or rod 23. The end of the arm farthest from the weight is connected with the direction changing. device 15. y In the construction shown this arm is provided with branches 24 and to these branches is connected a shaft 25 upon. which the direction changing devicerotates.

It will be noted that the weight and the arm are similar for each of the belts and that they are independent-of each other so that each belt will be kept in proper contact with y the roll of paper regardless of irregularities of the surface thereof. I prefer to have the belts-narrow and to use a number of such belts. In the construction shown four belts number may be varied if desired.

'are used but it is, of course,.evident that the m I prefer to have the belts driven and they may be run at any desired speed but preferably at a speed approximately equal to or somewhat less than the speed of the paper running to the press. The belts are arranged so as to have a com aratively lar e area of contact with the roll of paper. his result is secured by having a direction changing device above and below they roll, such as 13 and 18 and locating these direction changing devices beyond the vertical line passing through the face of the roll where it engages the be The web 26 of'the paper being The direction changing devlces 13 and 18 may, of course, be placed in any suitable position and I prefer to have them placed on a vertical line which passes on the opposite side of the center of the roll from that engaged by the belt so that there will be a ver large area of contact between the beltand the roll. In Fig. 1 the web of paper 26 passingfrom the roll to the press is shown as passmg downward in contact with the belt and over the direction changing devices 18 and 17 where it passes over the direction changing device 27 and separated from the belt passing downwardl to the press. Under these conditions I pre er to provide an additional direction changing device 28 for the belt which insures the separation of the belt from the paper as shown in Fig. 1. I

When the paper passes around the direction changing devices around which the belt also passes, sonic means is provided for arrangin the parts so that they will not interfere wit the proper operation of the. pa er. Under such conditions the direction c anging devices v17 and 18 are preferably continuous from end toend so as to act as rollers for the aper and at the points where the belts are coated, the direction changin devices are recessed or provided with annu ar ooves 29 into which the belts are received, t e grooves being of such depth that the belts will not project beyond the surface of the rollers, for otherwise they would cause bulging of the paper and interfere with the pro r operation of the device, see Figs. 4 an 5) In Fig. 7 I have s own a modified construction where the belt at the lower end passes around only one direction changin device 30.

felivered to the press passes around the direction changing devices or rollers 31 and 32 and then around the direction changing device 33 to the press. A spring 33a normally tends toaper taut.

kee the 'Iqie rol ers 31 and 32 may be driven fromthe-direction changing device 30 by means of a link belt 34 which passes around a sprocket.

wheel 35 rotating with the direction changing device 30, said link belt also passingl the sprocket wheels 36 and 37 on th irection changing devices 31 and-32. This construction avoids the necessity of providing the direction changmg device over which the paper around r asses, with annular grooves for the belts. n Fig. 2 I have shown a construction whereln the web of paper 38 from the roll Instead of running downwardly runs upwardly to the press around the direction changing devices 39 and 40. In this arrangement, the same number of direction changin devices may be used at the bottom of the be t if desired but they are not necessary it only being necessary to use one direction changing device in this position as shown in Fig 1 2. Some means is provided for stopping t e belts in the event the press should stop suddenly so that they will act as brakes on the roll of flpaper and prevent the paper from running 0 In Fig. 3 I have shown one construction for this purpose. In this construction the shaft 140 which drives the direction changing device 14 and the belts is connected with a driving shaft 41 by means of a clutch and means are provided for disconnecting the shaft 14a from the driving shaft 41 when the press suddenly stops or slows down, and for applying a brake to the shaft 14a. 7

In the particular construction illustrated, the shaft 41 is connected with the shaft 14a by a clutch 42 controlled by a sliding member 43 on the shaft 41. This sliding member is actuated by a lever 44 pivoted at 45 and provided with the usual fork which engages the member 43. The lever 44 is actuated by an electro-magnetic device 47 such as a s0- lenoid, the movable part of which is connected with the lever 44 by the member 48. The electro-magnetic device 47 is connected by the conductors 49 and 50 with a circuit controller on the press which completes the circuit therethrough when the press is suddenly stopped or slackened. The lever 44 also actuates a suitable brake for the shaft 14a. The clutch and brake may be of any suitable construction. As herein shown the sliding member 43 is provided with a conical shaped portion 51 which when the device is moved the left of Fig. 4, lifts the'ends of the levers 52 so as to actuate the clutch and connect shaft 41 with the shaft 14a. When moved in the opposite direction, the levers 52 are removed to release the clutch. The sliding member 43 is also provided with the conical shaped portion 53 which moved the braking levers 5'4 pivoted at 55 so as to cause the members 56 thereof to actuate the braking members 57. It will thus be seen that when the press suddenly stops or slows down, the electromagnetic device 47 will be energized and this will disconnect the shaft 41 from the shaft from the foregoing. When in operation and the belts are driven, they act-to assist in deit roll.

shaft 14a,

livering the paper to the press their preferred v 1.- A device for delivering paper to printaction eing a slight braking action. When one roll is about exhausted the shaft 1 is rotated and the adjacent roll is brought into contact with the expiring web, some adhesive material having previously been placed .on the end of the web of the new roll. As the new roll comes intocontact with the web from the expiring roll, the new roll is rotated and when the adhesive material comes in contact with the web ofthe'expiring roll, the belts press the web of the expiring roll against the adhesive, thereby'cau sing theweb of the new roll to be attached to the web of the old roll and pass into the press so that the supply of the aper is changed from the expiring roll to t e new roll. If there is any paper left on theexpiring roll when this occurs, the web is then severed so as not to interfere with the paper running from the new roll. It will be seen that due to the arrangement of the belts and their large contact area with the roll, of paper, this construction gives complete and accurate and positive control of the roll of paper from which'paper is being supplied to the press, both during the operation of the device and when the press is stopped. f 7' The grooves 29 in the rollers 17 and 18 are preferably of such depth that the belt 12 will be flush with the periphery of the If desired, the belts can be arranged so that they will be driven by the roll of paper instead of by power ap lied to the shaft 14a, that is, by the pull 0 the web by the press, this pull being transferred throughthe roll to the belts. This will give the desired tension to the paper passing to thepress. When the belts are not being driven by the the weights 21 will maintain the necessary tension on the belts to stop the roll of paper by friction in the event the press is suddenly stopped, thereby preventing the paper from being unrolled when'thi's happens. I may use the clutch 42 as a friction device to'regulate the tension produced on the pa r by the belts in the event the pressv is sud enly stopped.

It will be noted that each belt is provided with a looped portion, in the particular instance .being a portion extending around direction changing devices 14. It will further be seen that as the diameter of the roll of paper varies, the length of this looped portion changes. When the diameter is small,

for example, the looped portion becomes longer and when the diameter is large, the

looped portion becomes shorter.

In the particular device shown, this looped portion is provided with means for automatically varying its length as the diameter of the roll changes thus keeping-the belt n mg presses comprising a support for a roll ofdpaper, direction changing, devices above an below the roll of paper independently supported, a plurality of endless belts passing about sald direction changing devices;
