8 Claims. (Cl. 53-119) This invention relates to a machine for rolling and wrapping newspapers, periodicals and the like.

In using this machine, the papers are fed one by one and they are automatically rolled and, if wrapping paper is fed in, wrapped with this andfinally discharged.

A salient feature of the invention resides in the use of sliding pins or rods which move in from each side, and rotated, roll the paper against a plurality of surrounding and resiliently mounted rollers in two sets, the wrapping paper, if fed in, being simultaneously rolled so that adhesion of the moistened end completes the wrapping.

The invention will more readily be understood by reference to the accompanying drawings illustrating it to some extent diagrammatically. As shown in these drawings:

Figure 1 is an elevation of the machine from the back;

Fig. 2 is a sectional side elevation of most of the operating parts of the machine;

Fig. 3 is a similar view except that for the sake of clearness a number of the operating parts have been left out. This view is introduced to show the position of the rollers when the rolled and wrapped paper is discharged;

Fig. 4 is a sectional elevation through a pair of the driving pins or rollers and the means for mounting and driving the same;

Fig. 5 is a half sectional end elevation thereof;

Fig. 6 is a plan thereof;

Fig. 7 illustrates the lost motion arrangement in the one position, and

Fig. 8 is a view of the lost motion arrangement in the other position.

As shown in the drawings, the machine has a frame with vertical side members 10 and 11. There is a sprocket 12 driven from a convenient source of power, and on each side of this sprocket in the center there is a doublesided cam 13. Mounted on the same shaft is another cam 14. There is also a sprocket 15 on the same shaft which drives a one-revolution clutch 16 which will be associated with the supply and feed of the adhesive paper the mechanism of which can be of any desired form and is not directly the subject of any of the claims in this specification.

On each side of the machine are roller-supporting brackets 17 and 18. These act as supports and provide the bearings for two sets of inwardly facing circumferentially spaced rollers 19. Each bracket 18 is pivoted to one end of a supporting link 20 whereas each bracket 17 is similarly pivoted to the end of another supporting link 21. The far ends of these links are provided at 22 and 23, but they are not capable of any up or down movement.

There are control links 24 and 25, the ends of which are also pivoted to the brackets 17 and 1S, and these control links are pivoted to the ends of cranked levers 26 and 27 that in turn are operated by drag links 28 and 29. These drag links in turn are pivoted to a camcontrolled level-30 having a bearing roller 31 pivoted at 32 and at the end having a dead weight 33 to give stability. Operating on the supporting links 20 and 21 is a springloaded bolt 34 which tends resiliently to bring these links together at thebottom and so of course bring the two sets of rollers 19 near to each other.

The crank lever 27 has an extension 35 which is pivoted to a feed control rod 36. This in turn has springloading and acts on a housing 37 supporting'a holding roller 38. The housing 37 of the holding roller 38 engages against the spring loading of a control rod 39 ofa feed roller ill supported in a housing 41.

There are continuously driven rollers 42 and 43 which are in line with the feed roller 40 and holding roller 38 respectively and actually drive these rollers when they are brought into juxtaposition therewith with the paper or the like between them. Pivoted on each side of the housing of the feed roller 4t} is a pawl 44 below which there are stops that prevent the feed roller coming down when the pawls are in the position shown in Fig. 2. These pawls however are each connected by a link to a crank lever 45 and this in turn is operated by a link 46 pivoted intermediate of the ends of a trip lever 47. This trip lever is spring-loaded and in the position shown in Fig. 2, it is held by an interlocking lever 48. This interlocking lever is pivoted and at its upper end it is connected to an interlocking disc 49 or the like.

The table on which the papers are placed and fed is indicated at El), this table being of course slotted so as to expose the upper part of the continuously rotating rollers 42 and 43, and the table extends to a chute 51 into which the papers pass.

There will be a roll of gumm-ed wrapping paper 52 which feeds into the bottom of the chute by mechanism for cutting it off in appropriate lengths and inoistening the gum at one end, such mechanism being of any desired form but not being the subject of any special claim in this specification. It may, however, conveniently be controlled by the one-revolution clutch 16 on the latter being released from the trip lever 47.

On'each side between the two sets of rollers 19 operate rotating pins or rods 53 and 54. These each somewhat resemble the prongs of the conventional clothes pegs. They extend to be one unit to a pin 55 carrying doublecollar thrust plates. The cross section of a pair of pins is somewhat similar to a dumbbell or magneto armature.

Each unit passes through a housing 56 connected to the side frame and having a double set of ball bearings therein. A sleeve passing through the housing and the ball bearings is connected on one side to brackets 57 and 58 carrying double-row rigid bearings that engage the pin units. On the other side the sleeve is connected to a sprocket or chain pinion 59 and to this in turn are connected brackets as and 61 also having double-row rigid bearings. The pin units can therefore rotate together with the double-row rigid bearings supported by the brackets 57, 5'8, so and 61, but they can also move transversely in relation thereto. Where the pins pass beyond the rigid hearings on the inner side they will preferably pass through a facing plate 62 which is constructed closely to conform to the outline of the pins so as to prevent paper from being drawn in and entangled with the bearings.

Associated with the double-sided cam 13 there is on each side a thrust roller 63 or as. These are connected to sliding blocks 65 and 66 in turn connected to thrust rods 67 and 63. These thrust rods are pivoted to links 69 and 7% which are spring-loaded to hold them against the action of the thrust rods 67 and 68. Such links at the end have means for connection to the pins 55 carrying the double thrust collars at the ends of the pin units.

The lower part of the links 69 and 79 are cranked and extend to an end where they are respectively connected to lost motion control arms 71 and 72. These lost motion control arms are pivoted to the ends of a lever 73 that carries a roller 74 that is adapted to engage against the chain driving the sprocket 59 of the pin units. There is another lever 75 above the chain supporting another roller 76, spring-loaded so as to engage against the upper part of the said chain. The effect is that through the up and down movement of the lost motion control arms 71 and 72, the slack in the chain driving the pin units is taken up at the top as shown in Fig. 7, or at the bottom as shown in Fig. 8, the position shown in Fig. 7 being that in which the pins are in position, and that shown in Fig. 8 being the position in which the pins have been withdrawn.

When the apparatus is to be used for rolling bound periodicals or the like, it will be advisable to have a tray 77 supported at the bottom of the brackets supporting one set of rollers so that the end of the periodical is supported therein whilst being rolled.

The machine operates as follows.

A newspaper or periodical is placed on the table 50 so that at the side it passes against the interlocking disc 49. This moves the interlocking lever 48 and conse quently unlocks the trip lever 47. The paper is moved until the front part of it is beneath the feed roller 40. When the roller 31 of the cam lever 30 moves into the low part of the cam, as shown in Fig. 3, the drag link 29 is pulled down. This operates the crank lever 27 and its extension 35 which is pivoted to the feed control rod 36, which is thereby moved up. This upward movement is communicated to the housing 37 of the holding roller 38 and to the control rod 39 of the feed roller 40 which is consequently moved down and engages the paper which thereby comes under the driving impetus of the rollers 40and 42 and is moved on.

When the front end of the paper has reached a posi tion between the roller 43 and the holding roller 38, the cam control lever 30 is moved so that its roller is riding on the high part of the cam 14. Consequently the drag link 29 is moved in the opposite direction and this results in the feed control rod 36 causing the holding roller 38 to be brought down and to engage the paper whilst the feed roller 4'0 is simultaneously lifted and released therefrom. The paper then moves downwardly into the chute 51 between the two sets of rollers 19 supported by the brackets 17 and 18 and when it has reached the position when its center is about in line with the pins, the top end is still held between the rollers 38 and 43. At this position the pins 53 and 54, which are simultaneously and continuously rotating, come in, one pair from each side. This inner movement of the pins is modified by the lost motion mechanism previously referred to. The effect of this is that there is a short pause in the rotation of these pins so that the space between them is correctly orientated in relation to the paper on each side of which the pins are to pass. The pins thereupon commence to roll the paper up and the spring-loading of the two sets of rollers hold them tightly but resiliently against the paper being rolled.

When the paper has been rolled about one turn, the feed mechanism operating the supply of wrapping paper from the roller 52 will preferably be started so that it is rolled up with and around the paper and, if the extreme edge is moistened, will firmly hold the rolled paper together. Whilst the paper has been rolled (in all, about five turns), the pins have been slowly withdrawn until they are right clear of the wrapped paper, which is then only held by the rollers supported by the brackets 17 and 18 on each side. By this time, however, the roller 31- of the cam-controlled lever 30 has moved into the recessed portion of the cam, with the result that the drag links '28 and 29 are pulled downwardly. This action is communicated to the cranked levers 26 and 27. This in turn pulls up the control links 24 and 25, which opens the two sets of rollers against the spring-loading to the position shown in Fig. 3 and so discharges the rolled and/ or wrapped paper. By this time, another paper is being fed by the roller 40 so that the operation can be repeated.

When periodicals are to be rolled, the placing of a tray 77 at the bottom of the bracket 18 will support the bottom end of the periodical whilst it is being rolled as it will not normally be supported by the holding roller 38.

In the claims when reference is made to newspapers or papers, this term is to be deemed to include periodicals and the like.
