To all whom it may concern: 1

Be it known that I, ELLis W. CoornR, a citizen of the United States, residing. at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Web-Roll Supports for Printing-Machines, fully described and reprewnteri in the following specification-and. the accompanying drawings, forming apart of the same.

This invention relates to improvements in web roll supports for printing machines.

Webs are supplied to printing machines 4 from rolls'containing a core on which the web of paper is wound, the machines containing suitable supports in which these cores are mounted. In-the ordinary course of operation, it is necessary, when the paper is exhausted from a roll, to stop the machinegwhile anew roll is hoisted into place.

Thisstoppage of the machine causes a loss of time and consequent loss of product. It is the object of this invention to produce an improved'web roll support for use in printing and similar machines which is of such a character that web may be continu ously supplied to the machine from successive rolls.

"With this and other sists' in certain constructions, and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed out.

Referring to the accompanying drawingsFigure 1 is a side elevat on of a printing machine embodying the invention, the printing mechanism being diagrammatically impression cylinders or he lower deck are marked 5 and 6, and the printingcylinders 7 "and 8. An inkingmechanism of ordinary typa marked 9, is shown as coiiperating objects not specifi-- cally referred'to in view, the invention con shown as cooper guided to a single printing mechanism. In

the best constructions embodyingthe invention, furthermore, the roll supports will-be s0 arranged that the axes of the rolls on the supports will be at an angle to the axes of the cylinders of the printing mechanism;

In the particular construction illustrated, there is provided a frame embodying a pair of uprights 11, and a similar pair ofuprights 12. The uprights 11 are provided with two pairs of supporting brackets 13, 14 and the uprights 12 with a similar pair of supporting brackets 15, being shown as arranged on the outside of 16, these brackets the uprights and as supporting the cores of web rolls 17, 18,.19-and 20. Itwillbe observed that not. only are the uprights stationary but the supportingbrackets which i are carried by them are stationary onthe uprights, and the constructionis such that a roll of of brackets independently of the loading of the other pair. In other words, a roll is not loaded onto one pair of uprights and then transferred'to the other pair. a

Machines embodying the invention will include pressing devices and in the best constructions embodying this invention, these pressing devices will comprise rolls. In the particular machine illustrated, the pressing devices for the upper pairof web rolls comprise rolls 21, 22 and those for the lower pair of web rolls comprise rolls 23, 245. It will be observed that these pressing rolls are located between the web rolls and so that the paper may be loaded on each pair webs from the rolls may be readily led thereto. Any suitable devices may beemployed to direct web from the rolls to the-pressing devices. As illustrated, the'web from the roll. 17 is led to the pressing rolls 21, 22 by means of web guides 25, 26, a roll 27being lecated between these guides. Similarly, the web from tlieroll' 19- is led to the pressing rolls 21, 22 by guides 28, 29, a roll 18 and 20 to the pressing devices 23 and 24- is, in they machine shown, a duplicate of that already'described, and a specific description unnecessary.

of it is, therefore, unnecessary.

I Means will be employed for guiding the web from the pressing rolls to the printing mechanism. These means may be of any suitable type and will, of course, be varied in accordance with the variations of the constructions in which the invention is embodied. In the particular machine illustrated, these web guiding devices include driven rolls '33, 34, 35, and a bar 36, the bar operating to effect the change in the direction of travel of the web made necessary by the angular disposition of the axes of the web rolls with respect to the axes of the printing cylinders. After leaving this bar, the web passes over the usual guides, such as 37, 38, 39, 10 and ell between the cylinders land 3. The guiding means employed in connection with the-pressing cylinders 23, 24 are duplicates of those just described and a specific description of them is, therefore, The roll 33 may, if desired, be covered with rubber, or any other suitable material, to increase its driving effect on the web.

The operation ofthe mechanism, when it is desired to feed web from a new roll into the machine, is as follows: Assuming that the inachine employing the couples 1, 2, 3,

4 has been running on web drawn from the roll 17 and that the web is nearly exhausted, the web is started from the roll 19 and its I leading edge pasted. This pasted edge is the web from the roll 1 from the roll 17 has been exhausted, the nipthen advanced down the guide 28 in close proximity to the rolls 21, 22. Just as the last of the web from the roll 17 is passing between the pressing rolls, the pasted edge of the web from the roll 19 is advanced into contact therewith, and the pressure of the rollscauses this pasted edge to adhere to the web from the roll 17. The web from the roll 19 is then led throu h the machine by After the web ping roll 31 if employed, is swung over into contact with the roll 30.

axes stand at an angle to the printing mechanism it is v possible to hoist a web roll'into place in its support without interfering with the web which is running from a web roll on any othersupport.

Changes and var a tions may be made in constructionby which the invention is carr1ed into effect. The invention is not, therefore, to be confined to the particular construction hereinbefore shown and described.

What is claimed is 1. In a rotary printing machine, the com bination with a plurality of web roll supports, said supports being arranged so that the axes of the rolls are at an angle to the axes of the cylinders of the printing-mar chine, of pressing devices between which the webs from the rolls on the supports may be led, and web guiding means between said pressing devices and the printing mecha- IllSIIl. i

2. In a rotary printing machine having its an angle to the axes of the cylinders, of ro-.

tary pressing devices for each pair of roll supports, means for directing the web from the roll supports of each pair to the pressing devices of that pair, and web guiding devices between the pressing devices and the decks. 7 3. In a rotary printing machine having the cylinders arranged in a plurality of decks, the combination with two pairs of stationary uprights, of a plurality ofpairs of roll supports carried by the uprights, each pair of uprights carrying a pair of roll supports for each deck, the uprights and supports being arranged so that the axes of the rolls are at an angle to the axes of the cylinders, a plurality of sets of presser rolls, one set for each deck, located between the uprights, and means for directing the web from each pair of roll supports of each deck to the presser rolls of that deck.

In testimony whereof, I have hereunto set my hand, in the presence of two subscribing witnesses.
