This is a division of my patent No. 1,464,463, granted August 7, 1923, on an application Serial No. 253,314, originally filed September 9, 1918.

This invention relates to a paper changing and printing press'plant.

The principal objects of this invention are to provide an arrangement of a comparatively simple character by which a plurahty of web rolls can be held in readiness for connection with the websothat a continuous supply of web can be provided for a printing press or a plurality of printing presses at different levels; to provide an arrangement for this purpose by means ofwhich one s de of each roll, (both new and old) will be readily accessible; to provide a way by which new rolls may be carried through a series of presses while they are running to 20 supply them to other presses on the line;to save room in height; and to so arrange the web roll support with reference to the press that there will always be a space at the end of the press through which a roll can be moved'laterally.

Further objects and advantages of the invention will appear hereinafter.

Fig. 1 is a transverse sectional. elevation of a press room containing a plurality of presses and showing the layout oft-he press room in order to apply this lnvention thereto. the paper roll supporting mechanism being shown diagrammatlcally;

Fig. 2 is an enlarged elevation of two sets of web rolls looking at them in the same direction as in Fig. 1, but showing the details of construction in accordance with this invention; and

roll Fig. 3 is an elevation of the same taken from the side of the press constituting an end elevation of the Web rolls themselves,

The usual practice is to provide each paper roll with a spindle which is to be applied to the roll before it IS ready to be connected with the expiring web. According to this invention this process is entirely eliminated. thus saving time and expense, and the paper rolls are supported on paper cones running freely on the ends of studs,one of which can be forced into the open'end of the core so 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 mounted on carriages. The carriages are provided with driven propellers mounted thereon, which may be thrown into contact with a paper roll supported by the studs thereon. Thus, when one of the rolls is about to be exhausted its carriage is moved 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 is mounted on a carriage like the eX- hausted one.

lVhen the tworolls contact the pasted end I the fresh roll is, of course, carried along by the expiring web and at this moment a The arrangement of the press room plant,

according to this invention, is such that these paperroll carriages can be so located as to provide two free passages at either end through which fresh paper rolls may be transmitted preferably on overhead carriages or'cranes without interrupting the running of the press or presses. For this purpose tworolls are provided for each press mounted horizontally one above the other. Suitable platforms or galleries are arranged in such a wa 1 as to leave lull assa e-wa r on either side by which a fresh supply of rolls may be brought from storage. These passageways are located one between the; system of carriages and the end of the press, and the other at the other side of the carriage. v

The relative locations of the elements of this'paper roll changing system is important. 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 an desired number.

- may be used.

presses horizontally. The lower, tracks 12 provide for the application of the rolls to the lower decks of the presses, but if it is desired to apply them to the upper decks one or moretracks 13 above them are provided for that purpose. Their cranes 11 take the rollsfrom the lower track and lift them to the higherone. It is to be noted that I have shown two pairs of these tracks 12 and tracks 13 arranged in the same way. This is to provide two horizontal passage-ways through which the rolls are introduced into the space behind the presses and moved along thatspace to the proper press. These may be called the front and rear passage-ways, 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 any convenient well-known form The drums 16 carrying the cables can be moved cross ways on their carriages. The two passageways which have been mentioned are located respectively one just at the rear of the press frames and the other at the rear end of the space provided behind the press frames. Between these two passage-ways is-located a supporting frame 20 for the old and new rolls for each press. One of these frames is provided 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 horizontaldirection even while the presses are running, and without interrupting their operating in any way and the rolls brought up ad acent to the support 20 to which they Wlll 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 layout 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 an also easy access to the new rolls in addition to the provision of a clear passage-wayfor each of the rolls independently of the operation of the press. It is to be noted also that the web WV 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 sup-;

The brackets 25 are held in place by bolts l3sliding in grooves preferably running the entire length. of the carriage 24 so that they can move along these grooves .to accommo-r date the several widths of paper rolls.

Each carriage 24: is provided with a shaft having a hand wheel 46 and carrying two pinions 4E7 meshing with two stationary racks 48 by which the carriages can be moved along the tracks 21.

Under the carriages are provided horizontal shafts mounted to turn in fixed bearings. These carry sliding bevel gears 61 slidingly keyed to the shafts 60, and meshingwith the bevel gears 63 on shafts journalled in bearings 64 fastened to the carriages. On each-shaft 65 are fastened gears 66 which mesh with and drive gears 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 bearings 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 59 and also one propeller wheel 72. In this way it wil 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 Let it be'assumed that in Fig. 3 the new roll- R has just been moved in on the right hand Fig. 3.

carriage 11 and set in the position B. When the other roll 1' is more fully exhausted its carriage 24 and supports 23 are moved sideways by operation of the proper hand wheel 46 so that it comes over to a position to the right of them shown at the top of The new roll It is rotating at web speed. The old web is brought into contact with it so as to take its free end with it as indicated. Then a severing knife is operated to cut the old web and disconnect the old roll from the main web IV. 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 this it will be seen that the paper rolls 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 moved instead of the heavy new roll for purposes of paper change while the press is running, that passages are provided through 'which the new rolls may be carried through several presses while they are running for supplying some other press along a line and at the same time a continuous supply of web is secured to each press without the usual spindling of the paper rolls. Dispensing with this operation materially reduces the time and expense of attending to the change of the web.

Although I have illustrated and described only one form of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but what I do claimis:

1. The combination with a series of printing presses, of a support for a plurality of web rolls spaced from the end thereof to permit new web rolls to be moved along transversely between the support and printing presses while the latter are running, said support also having a space beyond it for a similar purpose.

2. The combination with a printing press, of a support for a plurality of web rolls located at the end of the printing press, with a space between the support and press to permit new web rolls to be moved along transversely between the support and printing press While the press is running, said support having means for holding rolls for an upper and a lower deck, and means for guiding theupper web above, and the lower web below, said space for receiving the new web rolls.

3. The combination with a printing press,

of a support for a web roll located at the end of .the printing press, with a space between the support and press to permit new web rolls to be moved along transversely between the support and printing press while the press is running, means for guiding the web above said space for receiving the new web rolls, and a track at the top of said space but below the webv for supporting a web roll therein. 4. The combination with a series of printing presses, of a support for a plurality of web rolls spaced therefrom to permit new web rolls to be moved along transversely between the support and printing presses, said support also having a space beyond it for a similar purpose, and transverse tracks for roll carrying carriages located above said spaces.

5. The combination with a series of printing presses, of a support for a plurality of web rolls spaced therefrom to permit new web rolls to be moved along transversely between the support and printing presses, a plurality of transverse tracks above said space and at different levels, and a roll supporting carriage mounted to run on each track.

In testimony whereof I have hereunto affixed my signature.

HENRY A. l/VISE WOOD.
