This invention relates to paper dispensers and particularly to apparatus of this character for dispensing a measured length of paper.

In cylinder printing presses the pad of the bed 5 roll is provided with an outer cover of oiled paper or the like. In applying the oiled paper to the bed roll the free end thereof is inserted in an opening or slot provided between the semi-cylindrical bed roll sections which may be moved away from each other to receive the end of the paper and then brought together so as to clamp the end of the paper in position. The oiled cover paper is quite expensive and heretofore there have been no means for accurately dispensing the desired length of paper and for turning down the desired size ap or margin which is inserted in the slot in the bed roll. It will be appreciated that in rolls of different lengths a different size strip of paper must be dispensed. It will also be appreciated that the ap or margin must be accurately measured and must be formed at right angles to the lateral edges of the pages. Heretofore a length of paper was dispensed and then it was trimmed to the desired size, with the result that there was considerable waste of paper. Also the accurate measurement and folding of the flap resulted in Wasting a considerable amount of time.

It is an object of this invention to overcome the difficultiesv heretofore encountered and to provide an improved paper dispenser particularly suited for dispensing a predetermined measured length of paper and for providing the strip of paper with a marginal crease spaced a predetermined distance from one edge of the strip and disposed at right angles to two of the edges thereof.

A further object is the provision of an improved paper dispenser of the above character in which the measured amount of paper that is dispensed thereby and also the spacing of the crease from the edge of the strip may be readily varied so as to adapt the dispensed paper to bed rolls of various sizes.

For a fuller understanding of the invention reference should be had to the accompanying drawings, in which Figure l is a side View of a paper dispenser embodying my invention;

Fig. 2 is a sectional View in the direction of the arrows on the line 2-2 of Fig. 4;

Fig. 3 is a sectional view in the direction of the arrows on the line 3-3 of Figure 1;

Fig. 5 is a detail view showing the creasing roller and one end of the feed rolls;

Fig. 6 is a perspective view of the end oi the dispensed paper showing the manner in which the marginal flap is turned down; and

Fig. 7 is a perspective view showing the dispensed paper formed into a cylinder in the manner that it is applied to the bed roll of the cylinder printing press.

My paper dispenser consists primarily of a pair of feed rolls I and II mounted on shafts I2 and I3 which are suitably journaled in the brackets or uprights I4 and adapted to feed or dispense paper from the supply roll l mounted upon the shaft I6 which is supported adjacent its two ends in slots I'I formed in the brackets I4 beneath the feed rolls I0 and II. The feed rolls I 0 and I I are preferably provided with a peripheral coating indicated at I8, formed of some suitable yielding resilient material such as rubber, so as to increase the frictional engagement and to insure positive feeding of the paper. The rollers are disposed in relatively tight engagement so that rotation of one will cause rotation of the other and likewise will cause feeding of a strip of paper projected between the rolls. I provide suitable means for rotating the rolls, preferably in the form of a crank or handle I9 secured to the end of the shaft I2 of the lower roll on the outside of one of the brackets I4.

It will be seen that due to the fact that shaft IB on supply roll I5 is mounted in the end of slot Il the supply roll can be readily and conveniently inserted in the brackets and removed therefrom. A roll of the desired type of paper should be inserted as shownand the end of the paper fed upwardly between the feed rolls I Il and II. As stated, my paper dispenser is particularly suited for dispensing heavy oiled paper or the like to be used as a protective coating on the bed roll of a cylinder printing press, and accordingly a roll of paper of this character is preferably inserted in the device.

So as to provide for a depending flap or margin of the desired predetermined width my apparatus preferably includes a creasing disk or rcller, indicated at 20, mounted on shaft ZI, which in turn is carried by the arm or bracket 22, The creasing disk or roller 20 engages feed roll I Il at a point in the paper feed prior to roll II. The periphery of the creasing disk or roller is preferably tapered as shown most clearly in Fig. 5 and it presses against feed I0 so as to impart a crease in the paper being fed therebetween as shown most clearly at 23 in Fig. 4.

For different bed rolls it is desirable to have margins or iiaps of varying width and for this reason I provide the creasing disk or roller with an adjustable mounting in the form of a collar formed at the end of the bracket 22 and disposed around the horizontal adjusting shaft 2l! which is preferably provided with graduations 25 as shown, so as to indicate the spacing of the crease from the edge of the paper. It will be appreciated that the creasing disk or roller may be adjusted along shaft 24 so as to provide a marginal flap of the desired width, and in order to retain the creasing disk or roller in the desired adjusted position I preferably provide a set screw 26 in the bracket 22, which is adapted toengage the shaft 24.

I also provide my improved paper dispenser with suitable means for indicating and limiting the length of the strip of paper dispensed thereby. This means preferably takes the form of a geared disk 21 of relatively large diameter mounted upon stubI shaft 28 which is` engaged and operated by the relatively small pinion 29 carried by shaft I2 of roller It! adjacent the handle I9. Formed around the disk at regularly spaced intervals adjacent the periphery thereof are a series of apertures 30 adapted tol receive a removable pin 3| which engages the stop 32 when it reaches the top of its path of rotation so as to limit the operation of the paper feed when the disk 21 has been rotated a predetermined distance. It will be seen that the stop 32 is secured to the bracket I4 beneath the disk 21 and in registry with the openings 33 when they are positioned adjacent the top of the disk, and is accordingly in the path of movement of the pin 3| when it is protruded through one of the openings 30. The distance between apertures 3B is uniform with the result that rotation of handle I9 a suicient distance to cause rotation of disk 2| for the distance between two adjacent apertures will result in the dispensing of a uniform predetermined length of paper. When the handle I9 is turned in a clockwise direction as viewed in Fig, l it will cause the paper to feed outwardly from the feed rollers and will also cause the disk 21 to rotate in a counter-clockwise direction in the direction of the arrow in Fig. l. Before turning the crank I9 the pin v3| is placed in one of the apertures 353 the desired distance from stop 32 so that the handle I9 may be rotated to dispense the desired length of paper. The handle I9 is then turned until the pin 3| engages stop 32. The operator will then know that the desired amount of paper has been dispensed.

So as to facilitate severing the dispensed predetermined length of paper from the strip of paper I preferably provide a cutting device 33 in the form of an inverted U-shaped channel member 34 serving as a` platen and an inverted U-shaped channel member 35 spaced from and positioned above the platen 34 as shown. The strip of paper is threaded between the members 35 and 34| and it will be observed that when the paper is dispensed by the rollers it will be fed through the cutting device as shown.

In using my device the creasing disk or roll is adjusted along shaft 35 to provide a margin or flap of the desired width. The supply roll I of the desired type of paper is then placed in the brackets I4 and the paper strip is fed upwardly between the creasing roll 2D and feed roll IIE, between the feed rolls IIJ and II and thence through the cutting devices 33. The leading edge of the strip of paper is then severed at the cutting device by tearing the paper along the straight edge at the forward end of the device. Pin 3| is then placed in the aperture 30 which will provide for dispensing of the desired predetermined length of paper. Crank I9 is then rotated in a clockwise direction as viewed in Fig. 1 with the result that the paper is fed between the rolls and thence outwardly through the cutting device, When the pin 3| engages the stop 32 it will be appreciated that the desired predetermined length of paper has been dispensed. The paper is then severed by tearing it along the straight edge of the cutting device. The dispensed length of paper which is indicated by the numeral 31 is then folded along the crease line 23 to produce the marginal flap 38. The flap is then inserted in the slot or opening in the bed roll of the cylinder printing press, and the paper rolled transversely of the strip around the roll as shown in Fig. 7. To dispense an additional length of paper the pin 3| is again placed the proper distance from stop 32 and the handle I9 is turned until the pin engages the stop. Where the paper is to be used with bed rolls of different axial lengths the spacing of pin 3| from stop 32 s Varied accordingly. The width of the margin or flap 38 may also be varied to suit the particular bed roll.

To facilitate adjustment of the paper feed so as to feed the desired predetermined length of paper the bracket I4 may be calibrated around the periphery of disk 21 so as to indicate the length of paper that will be fed if the pin is inserted in the aperture 30 positioned nearest the calibration or marking.

From the foregoing it will be appreciated that I have provided an improved paper dispenser particularly suited for dispensing paper to be used as a protective cover for a bed roll of a cylinder printing press and which may be adjusted to dispense any desired predetermined length of paper and to form a crease at the desired predetermined distance from one of the edges of the paper.

It should be understood that modifications may be made in the illustrated and described embodiment of my invention without departing from the invention as set forth in the accompanying claim.

I claim:
