This inventiomrelates to a, devicefor automatically continu'ingthel web supply to a web presswhen the supplying web roll beif -comes nearly exhausted. n

v The/principal objects of the invention are to provide a practical automaticemeans for attaching the leading endiof a new roll of paper to an expiring .webwithout stopping,

orslowing up, the press, yeven for aninstant; to vprovide means for rotatingthe new roll at vweb speedwhich shall Ahe separated from the means `for rotating the old roll; to-provide, means for supporting the old and new rolls in such a manner that the new roll is connected with the -web'without changing -the positions 4of either the new or 'oldl roll inthe. machine; to provide means for preventing ally contact of the running web with the new roll before itis time to connect them together ;'tol

provide means for automatically' operating the last named means to bring it out of its op; erative position and allow the web to contact with the new ro l at the right instant to bring the web into co tact with-a pasted area of the new rroll after thel new roll has had an opportunity to ,speed up to web speed; to provide means connected with the contact preventing means and operatable therewith' for starting the new roll automatically without interfering'with the operation o the press; to provide means connected with 'each new roll and locatedin a definite position with respect to the pasted area on its surface for controlling the operation of saidcontact preventingand rotating means; and to i provide improved automatic means for severing vthe web frol'n the exhausted roll. Y

Further'objects and advantagesvof the invention will appear hereinafter. l'

and use. Also theprinting press must reduced in speed until at the moment of I-"z plenishment-it is' -barely in motion and thev aixing of the forward end of thel new web l to the rear end of'the expiring web has had to be done mainly by hand. The web of the old roll has been severed on its core by hand while'I the motion of the other parts of 'the' device had to vbe guided manually; VThese defects rendered the machines subject to uncertain operation on account, of the manual control of 'certain features and didnot materially increase the speedof printing because of the need of practically stopping the printing r machines. The-main object of theseinventions has been to reduce the stoppage 4of the printingmachin'e as much aspossible. d above, the present invention is y As statef designed or the purpose ofv effecting the.

change automatically andwithout need of hand manipulation and without anynreduc-r tion in the' speed or yproduction of the press -it requires is tobe set `by very simple ac- .tion atany time before operation and then to start the. machine.l Then it will operate at a time determined-by the position of the parts ply for the old one while the press is running at full speed so that there is no reducing of the rate of production.

' Referring to the drawings, the paper replen-Al ishin printing press, only a part of the frame 10 device is shown as located beneath a of which is shown in the drawings. The replenishing device is shown as supported on two pillars 11 resting on afoundation. Be-

tween these pillars is a shaft 12 on one end of which is located a worm gearl 13 which meshes with a worm pinion 14- on the shaft of a vmotor 15. By means of this method ofdrive, the shaft 12 can be rotated and held 15 firmly in any position in which ,it may be when the motor is stopped. vlhis motor is intended to be operated intermittently as may be desired for the purpose of turning the shaft 12 one third of a revolution at a time.

2 'The' shaft can be turned by harld if desired.

Fixed on the shaft 12 between the pillars and adjacent to eachl of them are two-spiders.

Each of these. spiders is made up of a hub 16 I j and three arms 17 In theend of each of the spider arms is held amandrel 20 by means of a screw 18 entering a slot 19 in the mandrel. The mandrels on one set of spider arms are n opposite the mandrels on the corresponding spider arms. These mandrels are for secur-v 0 ing in the space between them thel paper rolls which are wound as usual upon cores 21 in the form ofpieces of pipe. The inner ends of the mandrels 20 are conical so that they may slipinto the opposite ends of the cores 21. Upon theI extreme conical end of each mandrel is a fixed key 22 which fits into a key-way cut into the end of the core, as shown in Fig. 4. It v, will be obvious that when a roll of paper is placed between a pair of spider arms and the respective mandrels are inserted into its core,

Vthe roller will be left suspended upon these The rot-ation of ,thej whole frame mandrels'. consisting of thelsix arms 17 bythe motor 15 is the meansused for raising and lowering the heavy rolls of paper. e

As there are three -pairs of spider arms all similarly equipped, three rolls of paper may Vbe carried at onetime by this device. In Fig. 5 I have designated the charging. posi- .tion C,preplenishing position B-and the running position`A .of the rolls. This may be considered the position of the paper rll carrying magazine at the beginning of the op: I

eration ofthe press. Fig. 1 shows the situation after the roll'A which is supplying theweb'W has been re- 'l duced down to a position in which it is. time to .connect the web with the second roll and con- .tinu`e .thesup'ply to the pressfrom that roll.

Thevweb runs from the expiring roll A on the arms 17 upwardly to a spring tension roller 25 which is? carried between levers 26 pivoted on the base or framell() of the press.

Lees-,eee

a stationary roll 28 to the printing press above. rllhis description applies to both po- A sitions shown in Figs. 1 and 5 and, in fact, to all positions'as Athe roll that is delivering to the press is always located in the position A after it is once connected with the running web. I

Two leather belts 30, engaging the roll A near its ends, run in the direction in whichthe web runs to the press at web' speed for the purpose of assisting the rotation of the roll A which is Lfeeding the web. Each endlessbelt 30 is suspended between two

drums

31 and 32, the upper one of which is mounted onea shaft 33. This shaft is positively driven through'axsproclfet 34 mounted on the shaft, I driven in turn by a chain from a sprocket 36 operated by the press, the operation of which is not illustrated herein. In this manner, it willbe seen that whenever the press runs the belts also will run and the paper roll against which they contact will rotate at whatever speed the press is moving. So the roll is mounted are located at a point almost directly under the center of the shaft 33 it Will be seen that, whether the paper roll A is large or small, the belts will lie snugly its surface in such manner that they can rotate itby .theirf propelling action upon it.

There are three arms 38 articulated loosely abo-ut the shaft 33 above the replenishing roll B. One is located at each side of the replenishing roll and one between them so that they all extend over the surface of this roll. Throughthe outer ends of these arms runs a shaft on which there are fixed three rubber l faced `propelling rolls 39.

This shaft is driven through a chain 29 from a sprocket wheel on the shaft 33` and this sprocket is driven' from the press as has been stated. It

will be seen,.therefore, that when the propelling rolls 39 are in contact with 'the upper paper rolLB they will propel it at the surface speed of the press in the same direction in which the paper is being drawn from the rollinFig. 1. f, U y y It -is to be observed that on the pillarsll a pair of arms 41 are pivoted and provided with a convex shield 42. `The arms 41 are articulated to a pair of links 40 extending up- 'Wardlywhich are lconnected to a rock shaft 43 through arms 44xed thereon. At the end of the rock shaft 43 there is fastened an armL 130 Springs 27 support the armsand the roller 25. The web then passes to the left and up around lvil) 45 which carries a stud 46 upon which is articulated a spring rod 47 carrying a strong spring 48. This rod slides in a bearing 49 on a bracket conveniently fixed on the press,y

trigger notch 51. In this notch lies a trigger 52 constituting the end ofan arm 53 pivoted on a bracket 54 fixed on the bottom of the press', if desired. The pressureof the spring 48 is exerted to turn the shaft 43 backwardly to the dotted line position shown in 3 but normally this is positively prevente Vby the trigger 52.

Swiveled on the rock shaft 43 is a hand lever 59 carrying a bolt 60 adapted to enter a drilled hole 61 in acolltar 58 fixed on the rock shaft.v .This bolt 60 is pressed by a spring 62 into locking position andis' provided with a hand grip 63 for withdrawing it. It is by means of this that the rock shaft is turned to the full line position shown in Figs. 1 and .3 and cocked in that position against the action of .the spring 48. From consideration of the parts so far described it will be obvious that the turning of the hand lever 59 from its horizontal position around to la `lower posivtion in line with the laxis of the notch 61 has turned therock shaft to the position vshown in Figs. 1 and 3. The handle is shown there as spring 48 the -with the shiel the upper web roll.

in the position to which it is brought after A the hand' grip is moved to'disengage the bolt from the notch 61 but under the action of the (parts are left in this position holding the web away from It has .beencustomary in machinesjfor this purpose to cover the forward or'leadingedge of the paper on the replenishing roll,.-in this case indicated at B, with paste as indicatedat 64 in Fig. 7, except that in that ligure I have shown. the roll as having three areas 65 Ientirely free from `paste. The rolls 39 are spaced as shown in Fig. 7 in the same relation as the clear spaces 65. This is to-provide la free unpasted path for these rolls to travel over so that no rpaste will borne into contact with them. The points of-the leading edge of the web ony this'roll are held to the roll by means of grease.

If it were not for the shield 42 the web would come into contactl with this web roll oneach mandrel 20, at one end of the machine. On account of the fact that this mandrel is" secured tothe paper roll through its key 22 it isv clearthat the mandrel will turn s positively with the paper roll if that is rotated andthus the cam.66 will rotate in exact time wlth the paper roll. It is to be observed that the cam 66, as shown in Fig. 5, corresponds in radial position with the center of the position at which the pasted portions 64 are located on the circumference of the roll. The lever 53 on which .the trigger 52 is mounted is connected through a stud 67 with a vertical rod68 which passes downwardly through an eye 6 9 carried by a horizontal push rod 7 0. This push rod 70 is carried by an extension 71 on one of the pillars 11 and a bracket 72 carried by a rod 3 which protrudes inwardly from the extension 71 of the pillar at'that end. On the inner end of the rod 73 is articulated loosely a finger 74. The vertical plane of this finger 74 is the plane in which is located the cam 66.A Therefore, as the roll revolves, the cam will raise the finger 74 once during each rotation. The rod 68 which hangs from the ,lever 53 is normally located at one side of the vertical planel in which the finger 74 moves upfand down so thatit will not be moved by it. Butti-'lis rod 68 is free to swing sidewise' slightly and can be so moved by the rod 70. This is moved tothe left by pressing on a knob on its end against the action of the spring 75 which normally keeps it in inoperative position. It is plain that when this rod is pushed inwardly it will carr the end of the rod 68 intoA the path of the nger 74 and the next time said finger rises it will lift the trigger arm 53 and thus disengage `the trigger 52 from the notch 51. Now, the spring 48is free to operate and'it moves the arm 45 over to the dottedlinfe position in Fig. 3 and swings the rock shaft 43 with it. a This raises the'rod 40 and thus swings the shield 42 up l into the dotted line position-shown in Fig. 1, Itis to be noted that this actionis automatic and that it takes place in definite relation to the pasted'spots 64 in their rotation. It may be statedhere that the turning of the rock shaft 43 into the lastlnamed position brings the notch 61 into registration witlrthe bolt 60 and the spring ,62, thus forces the bolt into the notch. Now, after the web is pasted, the operator pulls down on tlie lever 59 and swings :the rock' shaft back to its original' osition so as to cock the shield in its dotted trigger llever 59 .to horizontal position again ready for the next operation.

AThe propelling rollers for the replenshing web roll B at the topsof the machine 'have been mentioned-and the way in which they are operated will not be described. The rock shaft'43 carries at oneend a lever 80 which` has at its.end a stud'82." This stud works in s a' slotted link 83 whichispivoted by a stud 84 at its lower end to one of the' arms 38.

When the rock shaft 43 turns to the left *from its cocked position, as above described, the stud 82-will bring up against the top of the slot inthe 'lever 83 and raise this with the arm 38. Thistur'ns the shaft 33 and raises all three of thearms 38 and rubber 'rolls 39 so thatwhen the shield 42 is brought back to the dotted line position shown in F ig. 1 the rolls 39 will also be raised out of contact with the surface of the replenishingroll.

This having been accomplished, the mechanism .is allowed to perform the motion of replenishment. operator presses on the end of the rod 70. This movesthe rod' 68 over the finger 74 'and the next time the cam 66 comes around, that is, the next time the pasted spots 64 come into the position shown in Fig. 5, this will discharge the trigger mechanism and throw the shield from the position in lfull lines in Fig. 1 to thatl shown in dotted lines, so as to let the paper web come firmly into contact with the surface of the upper web roll B, as

Ashown in Fig. 6. It will be observed that this contact of the two webs cannot occur until one of the pasted rolls is in such position that y there shall have been' established a firm contact of the two webs before the 'paste of one web shall aflix it to the surface of the other.

This is regulated bythe shield which keeps the webs apart untilthe proper time. But the cam 66 determines the exact instant at which the 'contact is made and as the paste can be applied to the replenishing roll at a ,point that may always bear a definite relai blade up: It is held way down out of the way by a headed spring pin 95 slanted on one side lso as to act automatically to hold up the arm,l

having the weight, after'it has once swung 'above it assliown in Fig. 1 in dotted lines.

A rod 93 guided in a guide 94 normally moves down to engage this lever and holds the serrated blade 90 in an intermediate position but away from the nearly exhausted roll when the shield 42 is down. The upper end 'of this rod Iis pivoted to the arm'41 and obviously it is raised -when the shield moves up. Thus,

when the trigger-is released, the knife blade 90 comes up slowly intoV contact with the expiring web roll from its intermediate position and the expiring web will be severed from the running web at this time'immediately afterpasting.4 To summarize, the operation is as follows:

V Start-ing with the parts in the position shown A in dotted lines in Fig. v5, the web on the roll y at -A is allowed to run nearly out. Th'en the lever 59, with the bolt' 60 in the. hole 61, is

turned down and the shield 42, Propellers 39- yand rod 93 are thus brought down and the trigger 52 cocked. This bolt 60 is then dis engaged from the hole and the lever 59 raised i tothe position shown in Fig. 3. The 4reduction of the roll'A to nea-r its exhaustion point tsoon brings the web W into contact with the When the time arrives they Leases@ erator presses on the end of the rod and holds it in against its spring during prac- I ticallv a rotation of the roll B.1 At the proper time during that rotation the cam 66 releases the trigger 52. The spring 48turns the rock shaft 43 to the dotted line position in Fi 3 and the

arms

44, 45 and 80 turn with it. T ey raise the shield 42 and the propelling rollers 39 and allow the weight to raise the Ysevering blade 90 to the position shown in Fig. 6. Thus the pastin is done, and the old web severed. The ol web core is removed at A.

Now the motor 15 is started and themagazine turned a third of a revolution. The lever 91 is turned up by hand to move the severing blade down out of the way. Itis moved far enough for the lever to snap over the bevelled end of the spring pin 95 whichl holds the blade in its lowermost osition. When the new roll gets to the position B the old roll mandrels are in the position C ready 'to receive a new roll.'

It will be seen, therefore, that these operations are entirely automatic, while the machine is set by hand by turning the lever 59,

that could be done at any convenient time during the o eration of the new roll, but is not done unt' the old web becomes nearly exhausted because otherwise it would keep the new roll rotating unnecessarily. The only thingprequired to 'start the 'machine is to2.

touch the button constitutingthe end of the rod 70 and push itin. This, however, does not-by itself determine the exact instant of pasting but merely determines during which rotation of the web vroll B it shall takeiplace.

The exact instant of operation is determined l11o at full speed .Without any reductionat all by the cams 66; The press all the time runs and without the need of any further manipulation. The severing' blade, of course, is released and set in position ready to operate by' pushing vin thepin 95 as stated.
