22 Claims.
In ruling machines and like apparatuses where the sheets after passing through one instrumentality, as for example, ruling mechanism, are brought to a corner and then moved in a different direction to and through another instrumentality, as a second ruling mechanism, the speed of the apparatus as a whole has been limited by the necessity of bringing each sheet'to a stop and carrying it out of the way at the corner before the succeeding sheet enters the corner, thus'making the speed of the apparatus low as compared to modern machines of other types in this art.
One of the primary objects of the present invention is to provide a mechanism'that will receive a relatively large number of sheets in the corner andcause them to lap or pile, the'mechanism for taking the sheets out'o-f the corner and the instrumentalities that later operate on said sheets thus being permitted to operate at a higher rate of speed and increasing materially the output of the machine as a who-1e.
A further and important object is to provide novel lapping mechanism that may be used in other relations. i

Figure 13 is a sectional view on the line 1313 of Figure 10..
Figure 14 is a detail sectional'view on the 1414 of Figure 13.
Figure 12 is a sectional view on the line 12-12 iine sheets to be ruled are cut from the web of a paper roll 17, the cutting and feeding mechanism being indicated at 18. From this cutting mechanism they are delivered by a conveyor 19 to ruling disks 20, and from said ruling disksthey are carried by a conveyor Zlinto a corner mechanism 22.
The second apparatus 16 is located at right angles to the first apparatus with its receiving end at said corner, and the sheets are delivered from the corner as hereinafter explained to a conveyor 23 which carries-them to ruling disks 24. From these ruling disks the ruled sheets are transported by a conveyor 25 to a layboy 26. The apparatus, as thus far explained, is well-known, and it is believed needs no further detailing.
Referring. now more particularly to the corner structure, a suitable frame 27 is pro"- vided, and mounted on this frame are spaced sets of upper and lower coasting endless conveyor tapes 28 and 29, the upper stretches of the lower tapes 29 and the lower stretches of the upper tapes 28 forming a passageway that receives the sheets from the conveyor 21 of the first apparatus and carries them into the corner. The mechanism for driving these tapes may be varied, but as shown in the accompanying drawings, and particularly in Figure 1, a motor 30 is provided belted to a drive pulley '31 that operates the cutting mechanism 18 and then in turn a belt 32 operates the ruling disk rollers 20. From these rollers extends a drive chain 33 operating on a roller 34, around which pass the cords forming the conveyor 21. The roller 34 has a chain and sprocket drive 35 which includes a drive shaft 36 carrying a sprocket wheel 37. Passing around this sprocket wheel is an endless drive chain 38 that operates a roller 39 around which the lower tapes 29 pass. v I
The sheets that are carried 'into the corner by the conveyor tapes 2829 are brought to a stop by a bar'40 mounted on side bars- 41 carried by the frame 27. To carry these sheets out of the corner and deliver them to the conveyor 24 of the second apparatus 16, a suction roller 41 .is provided that is mounted on a shaft 42 extending longitudinally of the conveyor 2829. Suction is created in the roller 41 by means of a suction pump 43 which as shown in Figure 2 is preferably located at the feeder for the first apparatus 15, a suction conduit 44 extending from the pump 43 to the suction roller 41. In this conduit 44, and preferably at the first apparatus, is a suction controlling valve shown in detail in Figures 8 and 9. This valve includes a vertical casing 5 in which is a reciprocatory plunger valve e6 that is movable to a position to close the passageway through the conduit 44, and has a reduced portion i7 that is movable into communication with the passageway to open the same. The valve 46 is urged to its closed position by a spring as, and is moved to its open position by a cam 49 operating on a roller 50 that is carried by a swinging arm 51. The arm 51 is connected to the plunger valve 46. The cam 49 is rotated by a chain and sprocket drive 52 from the cutter mechanism 18 (see Figures 1 and 2). It will thus be evident that as the cam 49 rotates, the valve 46 will be reciprocated, thus alternately cutting off and affording communication between the suction pump 43 and the suction roller 41. The result is that the roller 41, which is constantly rotated, is intermittently made active in a manner well understood, so that the sheets which have been brought into the corner, are started by the roller 41 in a right angular direction to their direction of approach to the corner, and are delivered to the conveyor 23. In structures heretofore built, it has been necessary, so far as I know, to have the sheet that is in the corner carried out of the same before the following sheet enters as otherwise they will interfere and this has necessitated a relatively slow operation of the machine as compared to modern straight ruling machines. To overcome this difficulty and thus speed up the machine, means are provided for lapping and in effect piling the sheets in the corner. To this end there is provided in the corner and transversely to the conveyor tapes 26-29 a roller 53 that is located in advance of the suction roller 41 and is mounted on brackets 54 slidably adjustable on the side bars ila. This roller is driven at a slower surface speed than the speed of the conveyor tapes. As shown, the driving mechanism of the roller consists of an endless sprocket chain 55 driven from the roller 39 and operating a sprocket wheel 56 of larger diameter than the sprocket wheel on the roller 39. The sprocket wheel 56 drives a sprocket wheel 57 operating a sprocket chain 58 that drives one of twin sprocket wheels 59. These sprocket wheels 59 are carried on a bracket 60 adjustably mounted on the frame 27. That is to say, the bracket 60 has alongitudinal slot 61 through which passes a fastener 62. The fastener 62 when tight, of course holds the bracket 60 in its adjusted position. From the twin sprocket wheel 59 a sprocket chain 63 drives the roller 53. The bracket 60 is made adjustable in order that the roller 53 may be shifted to different positions along the side bars 41c and consequently along the conveyor tapes 2829. The brackets 54 on which the roller 53 is journaled, carry upstanding arms 64 that extend between the sets of tapes and have pivoted to their upper ends rearwardly extending hangers 65 on which are journaled idler rolls 66 that rest on the roller 53 between the tapes.
It will be evident from the above that as the sheets are brought into the corner, they will be pressed against the slower moving roller 53 by the idler rolls 66, and consequently their speed will be reduced until they come into contact with tho stop bar 40.
In advance of the roller 53 is a shaft 67 mounted on brackets 68 that are also adjustable on the side bars 41a. This shaft 67 carries a plurality of suction rollers 69, the upper peripheral faces of which extend between the sets of conveyor tapes 28-29 and thus intersect the passageway formed between the tapes of the different sets. The shaft 67 and consequently the suction roliers 69, are driven at preferably the same surface speed as the tapes 28 and 29. To this end the rear roller 39 drives through a sprocket chain 76 the shaft 67. As shown more particularly in Figures 10-14, each of the suction rollers 69 is provided in its periphery with a plurality of suction orifices 71 communicating with lateral orifices 72. The latter successively communicate with a suction port '73 formed in a head 74 that is fixed at one side of each of the rollers. A nipple 75, leading from each head, has a passageway '76 communicating with the port 73 and these various nipples are connected by conduits 7'7 with a manifold 78 that is in turn connected by a conduit 79 with a suction pump 80. Consequently when the pump 80 is in operation there is partial vacuum at each of the ports 73 and as the suction rollers 60 rotate, their orifices '72 successively register with the ports 73. The ports 73 being then at the tops of the rollers, suction is thus created through the peripheral orifices 71 as they pass through thespace between the tapes 28 and 29. It will be clear therefore that sheets entering the said passageway, are caused to adhere to the tops of the suction rollers 69.
Now referring particularly to Figure 7, it will be noted that a sheet is caught between the rollers 53 and 66 and thereby slowed down, just af er the sheet has passed the suction rollers 69. The front end of the next oncoming sheet is similarly caught by the suction rollers and as these rollers have their tops slightly above the upper stretches of the conveyor tapes 29 the front end of the sheet is lifted and moves along at a more rapid rate than the advance sheet. The consequence is that the second sheet is brought into overlapping relation with the first sheet and the sheets are therefore lapped and in a measure piled as they are brought against the corner stop 40. This does not interfere, however, with the removal of the sheets by the suction roller 41' for said roller will always operate on the undermost sheet and carry it out of the corner to the receiving conveyor 23.
As a consequence of this structure the apparatus can be operated much more rapidly, for a number of sheets can be delivered into the corner and the suction roller 41 speeded up to take them out as rapidly as desired and irrespective of the amount of lapping or piling that takes place.
This slowing down and lapping structure may be used in other locations as for example in the delivery of the sheets to the layboy. The layboy, designated generally by the reference numeral 26 may be of any desired structure, but the means for delivering the sheets from the second apparatus 16 to said layboy may be constructed as shown in detail in Figures 15 and 16. Thus there is disclosed at the end of the conveyor 25 another conveyor consisting of lower endless tapes 81 and upper coacting endless tapes 82. In the passageway formed between the upper and lower t pes is located a roller 83 similar to the roller 53 above described and operating at a surface speed which is less than that of the tapes 31 and. 82. Presser sheets formoving them faster and causing them to lap the slowed down'sheets.
rolls 84 rest upon the roller 83 and thus insure the engagement of the entering sheets with said roller 83. In advance or the roller 83 and preferably at the rear portion of the conveyor 25 are a' series of suction rollers 84 corresponding to the rollers 69 and cooperating withthe roller 88 in a manner already explained. 'Ihus withthis structure sheets delivered from the secondinstru- I mentality 16 are. slowed down by the roller 83 before they enter the layboy 26 and each sheet as it is slowed down is overlapped by the succeeding sheet broug t forward by the suction rollers 84*. I
