Application sue 1mm 25, 1902. Serial No. sine-z.

To all whom it may. concern:

Be it known that I, LOUIS F. a citizen of the United States, sir; in the city of New York borough of l? autism, in the State of New York, have invented certain new and useful Improvements in Apparatiis for Moving Paper-Rolls for Printing-Presses.

My invention relates to that class of printing presses in which the prinh ng is done upon a web of paper drawnfrom a roll and has for its object to provide an improved method of supplying the rolls of paper to a printing press and coincidently removing the spindle and core from which the paper has been used without stopping the action of the press or interrupting the process of printing. This object is accompied by providing a suitable support or holder to receive the rolls of paper which are to be used, suitable mechanism for conveying a roll of paper forward at the proper time to its position for use, suitable 'coiiperative mechanism for removing the spindle and core from which the paper has used, and means for transmitting the motion or the printing press to the operative mechanism of the attachments.

It is evident that a variety of meal appliances may be used to accomplish this work, and the purpose desired, besides the peculiar form of construction which I have chosen for the pu ose of -12 my invention, but I believe the device and construction shown, to be the simplest and most effective arrangement of parts for the accomplishment of the purpose of this invention.

The mechanism employed is hereinafter fully described and reference is made to drawings which form a part of the specifications and in which similar letters refer to similar parts throughout the several views.

Figure 1 is a central vertical section of a portion of the frame of a 1; ress, showing my invention attached to'the ame of a printing press and also with two projecting sup orting frames upon which is shown, in t e lower supporting fi'ame, the spindle and core of aroll of paper ready to be lifted out of its operative position, and the spindle and new roll of paper ready to be moved into its operative position; and in the upper support frame is shown the spindle and coreof roll of paper which have been lifted out of operative position, ands' pindle and new roll of paper which have been conveyed .into operative position for printing. A duplicate of my attachments as shown in this figure is secured to the opposite side scribed and illustrated in this figure, and for all intents and purposes the description is the same. Said attachments working together simultaneously constitute one complete set of my invenfion. Fig. 2 is a" cross section taken on the line 2-2 of Fig. 1 showing in part my invention as it appears secured to opposite sides of a printing press. Fig. 3 is a detail perspective view of clutch mechanism and means for working the same. Fig. 4 is a. detailed sectional view of lifting bracket with block showing. the dove-tail andspring bolt which hold Slide in position. Fig. 5 IS a detailed view of the arm with blohk for conveying new roll of paper into hearings in operative position for p T Referring more particularly to drawings letter A (see Fig. 1) indicates a part of a. flame of a printing press, to which is attached supporting flames a-a, having suitable a which act as bearings for the spindle w' 'ch carries. the roll of paper when in use.

2 and 2 represent hearings or journals secured to the frame for supporting the horizontal screw shaft C.

E is a block having threads on its internal surface to cooperate with the threads of the screw G by which E is moved forward and backward.

e is an arm movably attached to the block E for ging with spindle p for convey:- ing the spindle to its position for use into the bearings a. Said arm 6 is so mounted as to be thrown out of the way of any obstruction when block E is brought back to its starting position by hand wheel 6 D is an upright screw journaled in bearings d and d which are attached to the press e. The screws and D are cperated by an upright power shaft 6, which with the roll of paper P of the frame of the press desliding block is driven by cross shaft w and gears 6 3 which shaft and gears are a part of the mechanism of the printing press and transmit motion to the operative mechanism of the attachments. The upright shaft Z) carries a bevel gear 6 which engages with a corresponding gear 0 mounted on hollow shaft 0' which rotates loosely on the front end of horizontal screw C.

S is a clutch one part of which is mounted' fixedly on the screw C (see Fig. 3), the other part of the clutch being mounted loosely upon and rotated by the hollow shaft 0 by means of a feather 0 whichengages with the movable part of the clutch. The clutch S (see Fig. 3) is locked by lever L attached to a crcss-rod G to which is keyed an arm 9 which engages with the clutch. Lever L (see Fig. 3) is held in position by spring bolt Z attached to said lever and fitted into notches on projecting curved arm H. Screws C and D (see Fig. l) are operated together by means of beveled gears 0 and 03.

0 is a guiding rod attached to the bearings e and 6 block E in proper position when the screw C is revolved. The vertical screw D ro pels a block F upward or downward. Block F (see Fig. 4) carries an arm f which is movably mounted thereon so that it may pass any obstruction while being brought back to its starting position. Sliding arm f has a spring bolt 7' (see Fig. 4) attached to it so as to hold it in place.

0 (see Fig. l) is a guiding rod passing through block F which guiding rod is held in' bearings 11 and d \Vhen block F is at its proper height it strikes an automatic clutch throw-out K having a projection k at the upper end, which is in the path of block F.

K is attached at the lower end to g (see Fig. 3) which is keyed to a cross rod G and serves to throw clutch S out of engagement when the rod K is lifted by the action of the block F.

Z is a notch in arm H which receives the spring bolt 1 when the rod K is lifted, and serves to hold the clutch S out of engagement.

P represents the roll P (see Fig. 2)

a short arm assing from the paper e press through into t guide-rollers N and O.

N is a fixed roller held in a bearing V. O is an adjustable roller carried by the a in the bearing V and is held 1n an adjustable position by spring S Having thus described my invention as relates to its, parts, the operation of it may be briefly stated as follows: When a new roll of paper is needed, it is placed on the supporting arms a-a, and by handwheel C the blocks E with their movable arms are brought to the outer side of the spindle while the blocks F with their movable arms and which serve to hold the are brought to their positions underneath the spindle' from which the paper has been used. Paste having been applied to paper P it is now brought forward and connected to the paper of the preceding roll as it passes around the guiding roller N. Atthe same time by means of the lever L the clutch S is thrown into position and the screws which carry the hauling-in and lifting arms are set in motion whereby the spindle and core from which the paper has been used is lifted from its bearings and the new roll of paper is brought forward into the bearings from which the spindle of the preceding roll has been lifted. When the. block F on the upright screw has reached its proper position, it comes into contact with the projection at the upper end of the disconnectingrod K whereby the clutch is thrown out of connection and the motion of the screws cease. \Vhile this operation has been taking place, the paper on the preceding roll has been broken and the paper from the newly supplied roll follows through taking the place of that from the preceding roll. The spindle and core may now be lifted from the arms and removed" from the press. This completes the operation which is repeated as often as necessary in keeping the press supplied with paper.

-I do not limit my invention to the precise construction shownand described, as many changes might be made to the same without departing from the spirit of my invention or sacrificing its chief advantages.
