To all whom it may concern:

lie it known that we, HENRY A. l/Vrsn Woo!) and CONRAD Nonnrons, citizens of the United States, said WOOD residing at New York, in the county of New York and State of New York, said Nonnrons residing at Jersey City Heights, county of Hudson, and State of New Jersey, have invented a new and useful Folding and Collecting Q Mechanism, of which the following is a.

specification.

This invention relates to a folding delivery in which one of the cylinders thereof is adapted to out, fold and deliver a sheet on each revolution from a continuous web, or to collect on alternate revolutions, so as to deliver the successive papers folded in pairs. The principal objects of the invention are to provide an exceedingly simple arrangement for effecting the change, and more specifically, an arrangement in which the change is made simply by fixing a gear against rotating and rendering another gear inoperative,or vice versa; to provide for operating the piercing points of the cutting and collecting cylinder from the rotary car rier or delivery cylinder when it is desired to collect, and to operate said pins from a stationary member when it is desired to operate without collecting; also to provide im provements in details of the mechanism for operating the pins and improved means whereby one of the sets of grippers on the delivery cylinder can be thrown out of operation conveniently to permit their delivering only once for each revolution of that cylinder. 4 Y The invention also involves improvements in details of construction and combinations of parts as will appear.

Reference is to be had to the accompanying drawings in which,

Fig. 8 is a similar view showing the position of the parts at the next half revolution of the collecting cylinder with the two sheets just ready to be folded and taken away by the delivery cylinder.

The mechanism is shown as mounted on the frame A of a web printing machine. In the form illustrated, the mechanism consists mainly of a folding, cutting and collecting cylinder B, and a rotary carrier or delivery cylinder C. These cylinders are mounted on shafts 7 and 8, respectively, carried in hearings on the frame. The main driving gear train, not shown, imparts power to a gear 9 on the shaft 8 which meshes with a gear 10 on the shaft 7. These two gears bear the same relation to each other, as to diameter, as the two cylinders, and consequently drive the two cylinders at the same circumferential speed.

In the form shown, the cylinder B is half the diameter of the cylinder C and consequently rotates twice to each rotation of the latter.

Th cylinder B is provided with the usual cutting knife 11, folding or tucking blade 12, and pin points 18,. These pin points are arranged in a row and adapted to reciprocate, and each one is operated by a gear segment 14. These segments are mounted on a rod or shaft 15 which is adapted to escillate, and is provided with. a crank arm 16 provided with a pin 17 This pin operates in a hole in a circular ring 18. This ring is loosely mounted on the eccentrichub of a gear 19. This gear runs loose on the shaft 7. On the frame A is a bol-t21 which .is adapted to be moved in so as to enter a depression formed. in aboss 20 on the face of the gear 19. When this is done, as shown in F 1;; 2, the gear 19 will be held in stationary position. This is Q the condition required when the cylinder B is not collecting.-

291s provided in each crank lever 26 for On the shaft 8 isa gear 22 of the same diameter as the gear 19. This is designed to operate the gear 19 when the bolt 21 is inoperative, to the dotted line position in which it meshes with the gear 19.

Referringfnow to the rotary carrier or delivery cylinder .6, it will be seen that it is provided with two'setsof folding grippers 23 and 24. .Each of the grippers consists of a roller mounted to oscillate on its own end studs. The studs of the grippers 23 are mountedin hearings or boxes 25 forming part of the cylinder and of course movingtherewith. On one end of this gripper is fastened a crank lever 26 which has a projecting pin 27 operating in a groove of cam 28. This cam is fixed on the frame A. To prevent the operation of the crank levers 26 by the cam. 28 operating one pair of grippers when it is desired to collect, a set screw holding it on the stud of the gripper. One

of these is simply loosened when it is desired 1 to silencea pair of grippers so as to permit this'crank lever to sw ng loosely on the gripper stud. This is done when the grippers ofthis setare held in inoperative position by meansof the spring pin 33. The other'end of the gripper or the stud with which it isprovidedat that end, has a gear seginent 30 meshing with. a similar gear segment 31 on the end of the other gripper 24; The gear segment 30 is provided with afprojection or boss 32 carrying a spring pin 33. On the face of one of the bearlng' [boxes 25 is a hole 34 into which the pin 33 is adapted to be projected, in order to render these grippers inoperative. One pair of grippers is ordinarily silenced when collecting.

- The grippers 21operate in bearings 35 of a pair of bell-cranks 36. These bell-cranks are pivoted on studs .37 attached to the cylinder. They are provided with springs 38 to give the necessary flexible grip between the grippers. Adjustable stop screws 39 are mounted in puppets 4O fastened to the cylinder C to regulate the necessary openings between each pair of grippers.

I It isto be. understood that as we have shown the cylinder C of twice the diameter of the cylinderB,the latter cylinder will rotate' twice for each rotation of the former, and consequently there are two sets of grippers on the'cylinder' G and only one folding blade on thecylinder B. Whenfit is desired to dehvereverys'heet, the gear 19 is fixed in stationaryposition by means of the bolt 21 "and the gear 22 is moved over to'the full line position of F ig. 2 where it will be inoperative. Furthermore, both sets of grippers of the cylinder C are left in operative condition. In this case the operation of the cam ring 18 causes the pin points 13 to be projected once during each revolution of the cylinder B and that at a time when the cylinder .0 is in the position shown in Fig. 1. Thus the pins will have perforated the end of the web at this point at=the time at which the sheet in advance has just been severed. The pins are projected at this point and they are fully withdrawn when the cylinder B has performed the half revolution from the position shown in Fig. 1. In the latter position, theend of the web has advanced half way around the cylinder B and the tucking blade 12 is in position to tuck the web in between the grippers 23 and 24. The two cylinders are in the relative position then indicated in Fig. 6, but the pin points at the top are not projected, as shown in that figure, but are withdrawn while the grippers 23 and 24 are swung outwardly ready to grip the sheet and fold it over the folding blade. On the next half revolution of the cutting cylinder B, the parts thereof are again brought back-to the position shown in Fig. l. The grippers have carried the folded sheet away from the cutting'cylinder, the tail end of the sheet is just being severed by the cutting knife 11, and the leading end of the web has been punctured by the pin points, ready to repeat its operation.

In order to cause no unnecessary strain on the folded web while carried from the folding point to the point at which the grippers begin to grip, the cam 28 is so constructed as to allow the grippers to remain in a relative stationary position from the point at which they grip the sheet from the cutting cylinder, to the point shown at the left in Fig. 1. From this point to the bottom of the delivery cylinder the grippers move outwardly, that is, they have an e ecting motion so that they can eject the bite of the sheet'and drop it on the conveyor belt 411. Thus the grippers have a slight pulling-in motion, while the web is being tucked in the bite between them, but that in'm'iedia-tely ceases and from that point until the web is about to be ejected, they remain stationary. After this they comnience to eject the folded paper and drop it on the belts. The rest of the rotation is an idle one, so far as any action by these grippers on the sheet is concerned, but during that rotation they are brought slightly inwardly so as to get them ready for pulling in the sheet when they againreach the tucking-in position at the top.

l/Vhen it is desired to collect two papers on the cylinder B and then discharge them together, the pin bolt 21 is withdrawn from the gear 19, leaving it free to revolve, and

the gear 22 is moved along its shaft so as to mesh with the gear 19 and positively drive it at the same speed as that of the shaft 8. The set screw 2-9 connected with one of the grippers is loosened to render that gripper imperative, and the sn'ing pin connected with the same pair of grippers is moved over into the hole 34:. This effectively renders the grippers on one side of the delivery cylinder inoperative.

As the two gears 19 and have the same diameter, and as the cylinder B has half the diameter of the cylinder C, the gear 19 will rotate at half the speed, in revolutions per minute, of the cylinder B on the same shaft. Consequently, the eccentric ring 18 will operate the piercing pins 13 only once for each 'two revolutions of the cutting cylinder B. Furthermore, the delivery cylinder will operate to deliver a sheet, or plurality of sheets, only once for each revolution, instead of twice, as in the case above scribed. Therefore, the operation will he place as indicated in the diagrammatic views, Figs. 5 to 8.

In the position shown inFig. 5, and also shown in Fig. 1, a sheet has just been severed and the leading end of theweb pierced by the pins. Now upon the next half revolution of the cylinder B the pins are forced farther through the leading end of the web and it is taken half way around the cylinder. At this time the folding blade 12 is in folding position, but as the pair of grippers on the other cylinder which now come into registration with it have been rendered inoperative, no folding action takes place. (See Fig. 6.)

On the next half revolution the sheet is drawn the rest of the way around the cylinder B and the pins project through the leading end of the web again, while the knife severs the web at this point. This is shown in Fig. 7.

The cylinder B then rotates another half a revolution, which causes the pins at the top to withdraw from the double thickness of paper which they have previously pierced. At the same time the opposite pair of grippers on cylinder C, which is in operative condition, comes into registration with the folding blade and receives the double fold therefron'i. During the next half revolution the folded product is withdrawn from the cutting cylinder and the parts reach the position shown in Fig. 1 and are ready to start the collection of two more sheets.

It will be understood that although we have illustrated rid described a machine constructed for collecting only two sheets, yet the same principles can be appliedw'he'n a larger ni'imher' of sheets are to be collected, a rid other cl'i'ang'es can be made in details of constiaiction without departing. from the scope of the invention as expressed in the claims.
