N. Y., ASSIGNOR TO W'OOI) NEWSPAPER MACHINERY CORPORATION, 0F NEW. YORI{,N. Y., A CORPORATION OF VIRGINIA FOLDING MEGHANISM Original application filed October 28, 1926, Serial No. 144,877. Divided and this application led November 18, 1929, Serial No. 507,953. Renewed Mayll, 1932.

The principal objects of the invention are' to provide a folding mechanism in such relation to the press as to take up comparatively small space laterally and secure exact synchronism in its operation with thepress; to

design the presses and folder Vso that their' frames can be made up of separate parts united and oined to the other units without finishing the adjacent parts and avoiding the production of noise by the vibration of the elements to provide improvements in the cutting and .folding cylinders, and in .fact throughout the folding mechanism, whereby the web can be slit andV run into the folding mechanism 'along different paths and delivered in either direction without having to dismount the parts; and in general to so combine thes'e several'parts that a machine is secured which will run with few stoppages,

comparatively littlev oversight and produce a completed product in y a uniform manner and at the same time will take' up a comparatively small amount of floor space.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Y Fig. 1 is a side view of a folding mechanism constructed in accordance with this invention;

I have illustrated a press unit A provided with a vfolder C located at the end of the printing unit. In thiscase, the drive is through the impression cylinder shaft 12. The shaft 12, I call the driving' shaft and it is provided with an extension rigidly mounted on the end, coupled directly by a coupling 15 to a shaft 18 which drives the folder C. These driving shafts, are located at the samelevcl, namely the level of all the impression cylinders, so vertical shafts are eliminated with their gears.

This machine is set up throughout in accordance with the process setv forth in my Patent No. 1,498,769, granted June 24, 1924.

For example it will be seenin Fig. 2 that' there are a number of seats on the drawings marked 7. `In each of these places the parts ofthe frame are connected together by the casting of the seats y7 on thel two connected parts, or shafts, or rods are mounted by the casting of bearings 8in accordance with said patent. In this Way the parts of the machine are assembled without finishing and thus at a material saving in cost. Noise of vibration is also reduced as it is transmitted from one part to another. I have used the numerals 7 and 8 to designate these forms ofconnection throughout the several sheets of drawings andl withoutreference to the shape and special construction of the various seats and bearings to which it is applied. The machine can be assembled in the old Way, however. i

, The folding machine frame 9 and the press unit are connected together by a base 4 at the bottom and by frames 6 at the top. The frames 3 and 9 carry soft metal seats 7 at their lower ends having contact with similar seats on the base 4. The frame Gis shorter than the distance between the frame 3 of the printing unit and the frame 9 of the folding unit. The surfaces that are closely adjacent to each other in the assembled structure are Cil - ing cylinder.

` shaft 35a.

cast with depressions to be filled, instead of projections to be finished. These dovetailed depressions are used in the condition in which they are cast. The spaces between are filled with soft metal in the form of seats 7 such as have been described above. The soft metal seats transmit the vibrations practically without noise and, in fact, diminishes the amplitude of vibration. Bolts are intrduced through them, or other fastening devices as may be desired, but are not described herein in detail as they arev shown in my prior applications and patent above mentioned.

By reference to Fig. 2 it will be seen that the webs W and W1 are divided in two and I call the extra webs W2 and W3. They are brought along up to the drag roll 16 in substantially the same relationship as that in which they left the slitter 10, being carried over turning bars. They are separated at some point in their travel and are guided over four separate compensator rollers 17. These compensator rollers in each case are mounted on levers 17, one end of each of which is provided With a poppet and screw thread' for receiving an adjusting screw 18 which is operated by a hand wheel .19 fixed thereon.

Four of these are indicated in Fig. 2 for the separate adjustment of the four webs into which the two webs have been slitted in the manner described. These parts are mounted on the frame 6.

The folding machine'which is mounted on the frame 9 has the shaft 18 previously referred to as its main shaft. This is driven from the shaft 12 of the nearest printing unit through a coupling and it carries the foldwhee ica. y 22, Aboth mounted on a frame 23 pivoted'for adjustment. Y

The shaft 24 is carried by brackets 25 fixed 2() which, by a chain 21 drives a shaft l to the frame by seats 7 and carries a bevel gear 26 which is driven by bevel gear 27 on the shaft 16a. Carried by the brackets 25 at the two ends of the folding machine is a shaft 28 extending across on which are fixed arms 29, arms 30 and an operating lever 31. This operating lever has -an arcuate slot 32 into which extends a. screw 33 having 'a projection at the end by which Yit is screwed up to hold up `the lever 31 in any position in which it is placed. The arm 30 has a hole through it for the pin 34 which is pressed by a spring against a shaft 35a. through which the pin passes. One end of the lever 35 is bifurcated and provided with holes for carrying the This shaft is free to rotate and is adapted to receive the threaded end of the pin 34. This pin has a head 36 which can be pulled down to take the pressure of a spring 37. Normally the springVY forces thev lever upwardly at that end and forces a pro- On this shaft 18 is a sprocketA The chain passes over idlersprocketssimultaneously by the operating lever 31 and eachone of them can be released by its nut or head 36 independently of the others.

This drag roll is located in position to receive half the width of web from the presses and as each web is slit in two parts it carries w four webs. It delivers the slit webs to the former 39 and through forming rolls 40 and nipping rolls 42. One of the latter is yieldingly pressed against the other by a spring pressed pin 43. The web goes down through these between the folding cylinder and the cutting and collecting cylinder 46 which constitutes a part of the couple.

It will be remembered that theY folding cylinder shaft 18 is coupled by the coupling 15 directly to the impression cylinder shaft of the adjacent printing unit. Also the sprocket wheel 2O on the shaft 18 drives the drag roll. The shaft 18 is mounted on the frame 9 by soft metal bearings 8 at both ends and also the cutting and collecting cylinder 46 has its shaft mounted on the frame by similar bearings so that there need be no finishing of the frame in order to set these shafts and cylinders in proper position thereon. l

The shaft 18 is provided with -a gear 41 which drives a gear 44 on the shaft of the cutting cylinder 46 to drive the same. A gear 47 fixed on the shaft 18 4drives a gear 48 loose on the shaft of vthecutting cylinder 46. The gear 48 is provided with a cam groove 50 which operates a roll 51 on an arm 52 carried by the pin shaft 53. This shaft also has yarms 54 which, in accordance with the action of the cam, drives the pin rods 55. The pins operate in substantially the usual way in the usual guides. The cutting cylinder is provided with a knife 56 and cheek-block 57 which are located and operated as described in my applications above identified. The folding and nipping' rolls are driven by a sprocket chain 58 from a sprocket wheel 59 on the shaft of the cutting cylinder.

Mounted about the shaft of the folding cylinder is a cam 60 fixed on the frame and having an internal Vcam surface for operating two rollers 61. These rollers are on an arm 62 carried by opposite longitudinal shafts 63 on the folding cylinder. Arms 64 extend outwardly on the opposite sides of these shafts and in opposite directions. They are connected together by a spring 65 across the end of' the cylinder to normally hold these rollers 61 outwardly in Contact with the internal cam 60. These shafts 63 also have arms 66 for operating the pin rods 67 mounted in guides 68, for performing the iop usual function of the pins on the folding cylinder. Y

Also mounted on one of the soft metal bearings 8 and fixed to the frame 9y by a screw is a stationary gear 71 which, as

Jhe folding cylinder rotates, operates,through single intermediate, gears 72 carried by t-he cylinder on shafts 7 3. These shafts are mounted on apart of the cylinder by soft metal bearings 8 `constructed like the other bearings of this kind. The shafts 78 carry the usual folding blades 74 and operate them to bring them into the proper position for folding at the bottom of the folding cylinf der asis well understood in this art.

. ing roll is driven Vfrom the stationary one by a pair of gears on the rear ends of the folding roll shafts. f

Below the folding rolls the folded product of course is -delivered to a fan 80. This fan is mounted on a shaft 81 whichis driven by a chain 82 from a sprocket wheel 83 on the shaft of the cutting cylinder'46. The fanshaft is mounted in bearings on the frame 9 preferably. by means of metal bearings 8 as previously described and its blades are'designed as usual for receiving, the foldec product between them. It is shown in Figs. 4 and 6 .as in position to deliver to the left. It is provided with a guide 86 whichy directs the product into the fan and stops the rotation of the product when it reaches the lowermost point. The upper end of the guide is fixed to one of two rods 86a and the bottom on the shaft 91 or 91a.

I have shown .tighteners 87 for the chain 82 and 88 for the chain 89 which drives a sprocket wheel 90 from the fan belt shaft 81. The sprocket wheel 90 is on a shaft 91' on which is the counter disc 92. This counter' disc has the usual notch 98 for the counting roll 94. This roll is mounted on an arm pivoted on a shaft 95 and held against the edge of the counter disc 92 by a spring 96. The spring is adjustable by means of a slot 97 in the end for a bolt by which the end is held to a lug 98 on the frame.V The shaft 95 supports the guide 85 which extends up between the vanes of the fan for the usual purpose. Y l

The delivery belts 99 are carried by a set of pulleys 100 on the shaft 91 and a set of pulleys 101 carriedby a shaft mounted on a pair of brackets 102 constituting a tape delivery frame which is detachable and adapted to be liXed on either side of the main frame 9. These brackets 102 are hung on a shaft 104 or 95@l and have extended lugs 108` for engaging against the frame of the machine. On this cross shaft also are arms 105 carrying tightener pulleys 106 for the delivery belts 99. It will be seen from Fig. 6 that these parts are designed to deliver the products at the left in bunches as stated. This counter works in the usual way and the papers come down to the same and are stopped by the guide 86. They are dropped by the fan on the delivery belts 99 and bunched in bunches of fifty or one hundred, or any other number as may be provided for by the setting of the counter in its construction. Now referring to Figs. 8 and 5 it will be seen that the delivery mechanism is reversed but the same elements are employed. In the first place the fan is taken off its shaft and turned around end for end. The drive for the fan is changed so that the driving chain 82, or if desired a dierentchain 82a, is driven from a sprocket wheel 81 ont-he folding cylinder shaft 18. Thisobviously reverses the direction of the fan and causes the fan to deliver ,in the opposite direction. Additionalchanges are made as follows: Y The guides are taken ofi" the shaft 95 and put on the shaft a. The counter and connected parts are taken off the shaft 91. reversed, Vand put on the shaft 91a. The roll 94 and its arm on the shaft 95 is placed on the shaft 95a. Itis 'connected as before with the spring 96 but that `spring extends in the l opposite direction and instead of being connected with the lugV 98 it is connected with the lug 98a on the same side' of the frame. Likewise the tightener 88 which is mounted on the bolt vthat connects thespring with the lug is placed on the lug 98a andperforms the same function on the belt 89 as before but is on the opposite side. The chain tightener 87 also is used for the same chain 82 but in a different position. The reversal of the fan of course necessitates Vthe reversal of the guides 86. For that purpose they are removed from the shaft 91a and put on the shaft 91. The papers are stopped goingr in the opposite direction, but in the same position at the bottom of the fan by the guidesl 86 located in the new place.

In this way it will be seen that the reversal of the delivery can be brought about in a very simple way by turning the fan end for end and reversing the counter with its parts and the guides, etc. Also the brackets 102 are Vreversed and put on the other end of the machine. If Vit is desired to support the longer delivery belts at a point between pulleys and 101, a set of pulleys 107 are used. They are mounted on brackets 108 similar to the brackets 102 pivoted on the same shaft Y Lil -It will be seen therefore that the-folding machine is driven directly from one of the printing couple shafts of the printing chine without intermediate gearing, that it is all mounted on one frame, and has means for driving the` drag rolll and carrying the products from the drag roll'to the delivery belts on that frame. Also various parts are mounted on this frame by means of seats cast into place to avoid the finishing of the parts of the frame and cooperating elements. The folding and delivery ofthe products is done by the usual process in machines of this hind, but the reversal of the delivery is an important improvement and there are new details of construction. It will be observed that the parts are s0 associated as to permit of high speed and economical assembly of the m21-, chine. This folder is adapted to be set up with high speed printing press units and to receive the products of a plurality'of them and deliver their products in the form of completed newspaper sections at a very high speed all counted automatically.
