To all whom itmay concern:

Be it known that we, HENRY A. WISE W000 and JOHN. A. IsBELL, citizens of the United States, said Woon residin at New ork, said IsBnLL residin at Middletown, in the county of Orange an ,State of New York, have invented a new and useful Foldin and Cutting Mechanism, of which the fol owing is a specification.

This invention relates to certain new and useful improvements in folding and cutting. mechanism used in connection with web printing presses, and relates particularly to the folding, cutting and collecting cylinders.

The principal objects of the invention are to provide for smooth running and accurate. folding at a very high speed; to provide means whereby the moving parts can be adjusted while the machine 15 running; and to eliminate the hard running cams common in machines of this kind.

Reference is to be had to the accompany.-

7 is an enlargement of a portion of view on'the line 3-3 In the form of the invention shown in the drawings a frame 18 is provided for supporting shafts 19 and 20 for the folding cylinder 21 and the cutting cylinder 22' res ectively. These shafts are driven in any 1 esired way and are geared together by gears 23 and 24 so that inthe form shown the cutting cylinder rot a-tes' twice to each revolution of the folding cylinder, that being the ratio between their diameters. The

frame is provided with ball bearings 25 and tionary gear 30.' This gear, being fixed, is

designed for transmitting motion to planetary gears or pinions 31 carried by the foldmg" cylinder. Two of these pinions are shown. They have ball bearings 32 which support them from studs 33. carried by the folding cylinder at one end and by an out support 34 at the other end. This out sup:

port is carried by the'cylinder at a distance therefrom and rotates with it, being secured to the cylinder not only by the studs 33 but also by a series of bolts at 35. It is provided with a guard 36 covering the gearing and other mechanism contained between it and the end of the cylinder.

Each pinion 31 also meshes with a ear or pinion 40which is mounted on a sha t 41 supported in ball bearings 42 carried by the folding cylinder and by the out-support 34, gear .40 being fixed to the shaft 41. This shaft carries the blade holders 44 for a folding blade 45. Thisblade is adjustable by means of screws 46 carried by the holder. This holder 44 has a circumferential adjustment inside the gear 40. This is provided by means offriction disks 47 and 48 which are clamped in position by nuts 49. In the ordinary construction, in which the folding cylinder has twice the diameter of the cuttmg cylinder, there are two of these blade holders and the connected parts are duplicated.

Referring now to Fig. 4 it will be seen that the shaft 20 is not mounted directly on the frame 18, but is shown as provided with an eccentric box on each end of the shaft, in which box the ball bearings 26 are located. This eccentric box has worm teeth 51 cut in its periphery engaged by a worm 52 journaled in the stationary cap of the frame. By turning this gear when the machine is either running or stationary the eccentric can be turned and thus the distance between the two shafts varied to accommodate different thicknesses of product.

I Each of the cylinders is provided with pins 54 and 55 respectively. These two sets of pins are operated in the same way and only one of them need be described in detail. Referring particularly to Fig. 4, it will be seen that on the shaft 19 is mounted a gear 58 meshing with a gear 59 loosely mounted on the shaft 20. This gear 59 is driven at half the angular speed of the shaft 20. It is provided with an eccentric hub 60 on which is loosely mounted a ring 61. This rin is provided with a pin 62 connected wit a crank rod 63 on the cutting cylinder. On this rod is a loose sleeve 64 and a tight collar 65. The sleeve carries an adjustable pin 66 adapted to enter a socket in the collar and hold the sleeve rigid. Thus the oscillation of the rod oscillates the sleeve and a gear segment 67 adjustable thereon. This engages annular grooves 68 in a pin 54 and reciprocates it as the cylinders rotate. Thus the rotation of the shaft 19 rotates the gear 59 and thus moves back and forth the pin 62 and thereby, through the connections just described, oscillates the gear segments 67 and reciprocates the pins 54. 1 When the cutting cylinder is used as collecting cylinder one set of pins in the folding cylinder must be silenced, that is, located in such position that the points will not protrude :at'any time durin the rotation of the cylinder. When it is esired to do this the movable pins 66 are screwed endwise by hand until their ends enter holes 69 in the folding cylinder. At this time the I opposite ends of the pins 66 have left the sockets in the collar 65 and the crank rod 63 is free to revolve loosely in the sleeve 64. If it is desired to silence the cutting cylinder pins permanently, as for instance during a long run of insert pa ers, the gear 58 can be moved to the dotte line position in Fig. 4. This stops the pin moving means on that cylinder alto ether. 69 is a grease cup.

The pins 0 the'two cylinders are operated in the same way, but the two crank rods in the folding cylinder are given their motion by two eccentric arms 7 O mounted loosely on an eccentric hub 71 which does not revolve. The point of disappearance of the pins 55 is adjustable to obtain a correct fold by the blade 45. This is accomplished by a worm 75 on the, cap 27 operating a shaft 76 and turning the eccentric hub 71 on the shaft 19. This hub has teeth on its periphery for that purpose. This adjustment of course can be made while the machine is in motion.

Assuming that the cutting cylinder is to be used as a collecting cylinder, and that one of the sets of pins of the folding cylinder is silenced, the operation is as follows The first section of paper is taken by the pins of the cutting cylinder and carried around its periphery, then it is taken by the active pins of the other cylinder on top of the second section of papers, the pins 54 withdrawn, and both sections are then carried around the folding cylinder by one set of pins 55 thereon. They then assume a position ready to be folded longitudinally by one of the blades 45 and pushed between the folding rolls 29. The pins 54 are withdrawn at the proper time with relation to the cut so that the paper is folded centrally. On

account of one set of pins being silenced the indicates by the dotted line 80 the path of the folder. The dotted line 81 indicates the path of the end of one set of pins 55.

It will be seen therefore that the usual hard running cams which batter-out at high speed, but are employed in this class of machines, are entirely dispensed with and that a machine is provided which will run smoothly at very high speed, and fold accurately, and that the various adjustments can be made while the machine is running. At the same time the machine is comparatively simple and its parts are not likely to get out of order readily in operation.

Although we have illustrated and described a single embodiment of the invention we are aware of the fact that the principles thereof can be carried out in other forms without departing from the scope of the invention as expressed in the claims.
