I ,PAPER'BOLII'CHANGING' APPARATUS.

Application filed September 9, 1918, Serial No. 253,314. Renewed January 8,1928.

To all whom it may concern: Be it known that I, HENRY A. WISE Wool),

a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new' and useful Paper-Roll-Changing Apparatus,

of which the following is a specification.

This invention relates to a system of paper roll changing apparatus for printing presses and includes details of construction of the.

parts thereof.

,The principal objects of this invention are to provide an arrangement of a coinpara tively simple character by which a continuous supply of web can be provided for a printing press -or a plurality of printing presses; to provide an arrangement for this purpose by means of which one side of each roll. (both new and old) will be readily acoessible; to provide means by which a comparatively small amount of power willbe required to change the positions of the rolls for the purposes press is running; to provide a wayby which new rollsmay be carried through a series of presses while they are running to supply them to other presses on the line; to reduce t-he time and expense required in preparing 'the rolls for application to the presses by dispensing with the usual spindling thereof; to save room in height; and of course to provide for attaching the expiring web to a new roll while running the new web at web speed and severing theexpiring web after the end of the new web is attached to it.

Further objects and advantages of the invention will appear hereinafter. Reference is to be had to the accompanying drawings, in which Fig. 1 is a transverse'sectional, elevation of apress room containing a plurality of presses and showing the lay-out of the press room in order to apply this invention thereto, the paper roll supporting mechanism'being shown diagrammatically;

Figs. 11 and 12 are diagrammatic views showing the method of attaching a fresh web to an expiring one in accordance with this as to hold firmly the paper roll in central position, means being provided for positively transmitting the rotation of the roll to the taper cones. These cone studs are supported .on suitable bracket bearings which are The carriages are provided with driven propellers mounted mounted on carriages.

thereon, which may be thrown into contact with a paper roll supported by the studs thereon. Thus, when oneof the rollsjis invention, and illustrating different positions about tobe exhausted its carriage is moved I along the tracks toward a fresh paper roll which has been pasted already, and is being caused to revolve at the proper speed by its own propellers. The fresh paper roll of course i mounted on a carriage like the ex-,

hausted one.

en the two rolls contact the pasted end paper roll on its cone studs. This fresh rollof course is properly pasted, its propellers brought into contact with it,'and started up when the other roll is about to be exhausted.

The arrangement of the press room, according to this invention, is such that these paper roll carriages can be so located as to' provide two freepassages at either end through which fresh paper rolls may be transmitted preferably on overhead carriages or cranes without interrupting the running of the ress or presses. For this purpose two rofis are provided for each press mounted horizontally one above the other. Suitable platforms or galleries are arranged in such a way as to leave full passage-way on either side by which a fresh supply of rolls may be brought from storage. These passage-ways are located one between the system of carriages and the end of the press, and the other at the other side of the carriage.

Referring more especially to Figs. 1 and 3, I will first describe the-relative locations of the elements of this paper roll changing system. It is to be noted that a plurality of'press frames 10 are indicated in their usual relationship to each other in the press room. This invention can be applied to one or any desired number.

At the rear of these presses is a. space in which the new and old web rolls are located, and beyond it is a roll storage place as indicated in Fig. 1. The rolls R in their usual.

condition are taken from this storage place by means of'overhead carriage or cranes 11 operatlng on horizontal overhead tracks 12 and brought out into the space behind the presses horizontally. The lower tracks 12 provide for the application of the rolls to the lower decks of the presses, but if it is deslred to apply them to the upper decks one or more tracks 13 above them are provided for that purpose. Their cranes 11 take the rolls from the lower track and lift them to the higher altitude. It is to be noted that I have shown two pairs of these tracks 12 and tracks 13 arranged in the same way. ThlS is .to provide two horizontal passageways through which the rolls are introduced mto the space behindthe presses and moved along thatspace to the proper press. These may be called the front and rear passageways and are indicated fully in Fig. 3.

The rolls R, of course, are supported by straps 14 and cables 15, the operating mechanism for which need not be described in detail as anv convenient. well-known form may be used. The drums 16 carrying the for'each four rolls in active service in the form illustrated, and it will be seen that the rolls R can be moved along the tracks 12 or 13 laterally with respect to the presses through free spaces or passage-ways in a horizontal direction even while the presses are running, and without interrupting their operation in any way and the rolls brought up adjacent to the support 20 to which they will be applied, and also brought to the proper height. They can then be mounted on these supports in a manner to be described.

From what has been said and shown with relation to the lay-out of the plant, 'it will be seen that the paper rolls are changed horizontally, thus requiring less power, saving room and height, providing easy accessibility to one side of each roll, and also easy access to' the new rolls in addition to the provision of a clear passage-way for each of the rolls independently of the operation of the press. It is to be noted also that the web W passes beyond the crane carriage,

the upper one passing above it and the lower one below the space in which'the rolls are brought in so that there can be no interference.

Fixedly mounted on the floor or any solid stationary supports are tracks 21. On these tracks run rollers 22. The rollers by means of legs 23 which have flanges acting as ways slidingly support carriages 24. There is one of these carriages for each pair. of legs. These carriages carry brackets 25 for supporting the web rolls. Each bracket is provided with a cylinder 26 in which slides a vided for keeplng the stud in proper position. A screw'29 operated by a hand wheel 30 mounted on an end 31 of the cylinder 26 moves the stud back and forth. On this stud 27 is a reduced cylindrical portion 32 on which is revolubly 'mounted a cone 33. This cone is provided with a key 34 adapted to engage in a key slot 35 in a metal tube'constituting a paper roll core '36. In the form shown in Fig. 4: this supporting member on one side is provided with a brake pulley 37 fastened to it by means of bolts. In'the form shown in Fig. .10 there is no difference except that a brake pulley is used on both studs. These brake pulleys are used for the usual purpose, and only one of them is required ordinarily, but two of them are of value in case one key slot 'ves way through a sudden stoppage of tile press or any damage in transportation. In that case the other pulley could be used without any loss of time. Pivoted on lugs 40 are the usual brake shoes 41 with their adjusting hand wheels. 42.

The brackets 25 are held in place by bolts 43 sliding in grooves 44 preferably running 'the entire length of thecarriage 24 so that theycan move along these grooves to accommodate the several widths of paper rolls.

' fixed to the screw and can be turned to move the carriage along and thus adjust the roll lengthwise with respect to itself along the carriage 24.

A shaft 54 journalled in bearings 55 car-- ries a web severing knife 56 fastened to arms 57 which, are keyed to the shaft 54. A hand lever 58' actuated by means of a spring 59 normally holds the knife in the position indicated in Fig. 3 out of the way of the two revolving paper rolls.

Under the carriages are provided horizontal shafts 60 mounted to turn in fixed bearings. These carry sliding bevel are 61 in brackets 62 fastened to the carriages so as to move with them along the shaft. These bevel gearsare slidingly keyed to the I shafts 60 and drive other bevels 63 mounted on shafts journalled in bearings 64 fastened to thecarriages. On each shaft 65 is I fastened a gear 66 which meshes with and drives a gear 67 running loose on a propeller arm shaft 68. Each of these gears 67 meshes with a gear 69 fastened to a propeller shaft 70. This propeller shaft has hearings in arms 71 which are fastened on the propeller arm shaft 68 and swing with it. On each of these shafts is of course one gear 69 and also one propeller wheel 72 in this way it will be seen that the constantly driven shaft 65' operated from any desired source of power constantly drives the propeller shafts and consequently all the propellers. When it is desired to throw the propellers into contact with a new web roll, this is done by operating -a hand wheel 73 on a worm' 74. This operates a worm wheel 75' which meshes with this worm and also is fastened to the shaft 68. This shaft therefore is turned and the propellers moved into contact with the new web roll or out of contact 'with it as may be desired. These devices,

of course, are located in each web roll osition so that each web roll is operated independently by its propellers and all driven preferably from the same source of power. When a roller is nearly exhausted a new one R is lifted in the storage room as lndicated in Fig. 1- and-moved on its carriage past the other folls as indicated inoFig. 3

along one of the spaces above described. Let

it be assumed that .in Fig. 3 the new roll R has just been moved in on the right hand carriage 11 and set in the position R. lVhen the other roll R is more fully exhaustedits .carriage 24 and supports 23 are moved sideways by operation ofthe proper hand wheel 46 so that it comes over to the position shown at the top of Fig. 12. The new roll R is rotating at webspeed. The old 'web is brought into contact with it so as to" take its free end with it as indicated. Then the severing knife 56 is operated to out the old web and disconnect the old roll from the main web W. Now the old roll spindle is removed and the carriage brought back to its original position. The new roll R stays where it is first placed until it becomes almost exhausted.

From thisit will be seen that the'paper roll" are changed horizontally, thus saving room in height, that the rolls are all readily accessible from one side, that power is saved because it is the light expiring roll that is 1 moved instead of the heavy new roll for purposes pf'paper change while the press is runn1ng,' th'at passages are provided through which the new rolls may be carried through several pressesfwhile they are running for Y supplying some other press along a line and at the same time a continuous supply of web is secured to each'presswithout the usual .spindling of the paper rolls; -.l)ispensing with this operation materially reduces the time and expense of 'attendingto the change of the web; 1
