.sPEcrEIoArroNrorming pm of Lears Patent Vno. 721,840, dated March 3, 1903. Application filed September '7, 1900. Serial No. 29,256. (No model.)

To all whom, it may concern:

Be it known that I, WALTER SCOTT, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented a. certain new and useful Improvement in Delivery Mechanism for Printing-Presses, of which the following is a specification. l

My present invention has for one object the provision of means for cutting a web (or webs) into sheets and to deliver these sheets with or without collecting cuts; and it consists of certain features of construction, parts, arrangements, and combinations hereinafter described, and more particularly pointed out in the appended claims.

In the drawings hereunto annexed and forming part of this specification, Figure .l

is a diagrammatic side elevation of a print-V ing-machine and folding and delivery. mech-S anism, the frame and other parts being omitted. Fig. 2 is an end view, with frame omitted, of folding and delivery mechanism ernbodying the present invention. Fig. 3 is a view,partlyin section and partlyin projection, upon the plane indicated in Fig. 2 by the line X X. Fig. 4 is a view from the leftpin Fig. 2 and showing certain parts shown in Fig. 2.

The web passes over suitable guides to and between the impression and form cylinders of the printing-couples ct Z7 c d and up over a guide cylinder or roller c, thence to and between the impression andA plate or form cylinders of printing-couples f g lt i, thence about suitable guides tothe guide-cylinder k and the V-shaped former V to drawing-rollsl and cutting-cylinders C U. The dotted lines indicate how the web may be'V led from the couple bto the couplef and also from th'e couple d to the lower guide-rolls, or the web may be brought vin below couple c, which would then be driven in the reverse direction from that in which it is Ydriven when the web connes from above, pass upward through couple cand around the impression-cylinder thereof, and then down to the couple d.

The vertical row of couples a b c d is separated considerably from the vertical row of couples f g h t', thus providing space into which workmen may pass and obtain easy access to all the form and impression cylinders.

The cylinder C has a plurality of cuttinggrooves m,(three in the instance shown in the xdrawings and the cylinder U is shown of a size requiringvthat it have two knives n. The surface of cylinder C is raised adjacent and at each side of -grooves min order to push in the rubber sheaths of knives yn during the cutting operation. Behind each groove m is a set of im paling-pins 0,which are pivotally connected with arms from shafts p, journaled in cylinder O. The pins o are guided by the cylinder C, as usual. Spring-rods q, of usual construction, connect with arms from shafts p and rotate them until stops r arrest them, thus protruding pins 0 from cylinder .0. Each shaft p has a roller s connected therewith for coaction with certain cams hereinafter mentioned.

t represents cross-heads on shafts u, which are journaled in cylinder C, and o represents rollers journaled on heads t.

fw represents double-edged folding-blades carried by shafts u.

a: is a circular track for rollers o, and it has a cam y, into which rollers o pass at times or when blades zu are to crease the sheets.

'z reprcsentsbrackets by which raceway Qc is supported from the framework.

The grooves m divide the surface of cylinder O into three sheet-receiving surfaces 1 2 3.

The shaft 4 of cutting-cylinder C has fixed thereto a gear 5, which drives a pinion 6 on an endWise-rnovable shaft 7, journaled in the framework. Flying cams 8 are fast to the gear 6, which gear is to gear as2 is to 3. The shaft 7 may be moved endwise to carry cams 8 into and out of the plane in which rollers o move about shaft 4, as by means of a cam 9, fast to shaft lO of cylinder U, a lever 11, eX- tending from sleeve 12 to and operated by the cam 9, a lever or arm 14 on sleeve 12, and a lever 15, journaled on the same shaft 13 as levers 1 1 and 14 and connected with lever 14 by a removable screw-bolt 16. The lever 15 vhas an antifriction-bowl thereon which engages with a circumferential groove in the shaft 7. Since cylinder U is two-thirds the size of cylinder C, it results from the above 'construction that cams 8 are withdrawn from the plane of rollers c every other time a blade w passes cam y, or the cams 8 may be locked in said plane of rollers c by removing bolt 16 from levers 14 15 and inserting it in lug 17 ICO and a threaded hole 18 in the framework, thus causing each blade w to be rotated each time it passes cam y.

When cams 8 are withdrawn from the plane of rollers fv, the cam y may be filled to convert ring m into a complete circle. For this purpose I show an arm 19 on shaft 7, which is angled around outside ring and has a filling-head 20 thereon, which is adapted to enter cam g/ from the side and to supplement and convert ring into a complete circle.

2l is a guide and support for the arm 19, which is loose on, but which moves axially with, shaft 7.

22 represents folding rollers or jaws between which the sheets are forced by blades w. These rollers are driven in opposite directions, as usual.

23 is a vibratory cam fast on a shaft 24, journaled in the framework, and 25 is an arm fast on said shaft also. rlhe shaft lO hasa cam, as eccentric 26, fast thereon, which cam coacts with a roller 27 on a pivoted arm 28, and arms 25 and 2S are connected by a link 29, pivotally connected with each. A springrod 30 presses arm 28 toward cam 26. This construction provides a means whereby cam 23 may be operated to withdraw every other set of pins'o to cause the release of sheets thereby when cani 9 causes cams S to rotate alternate blades w.

When cams 8 are set to rotate each blade w every time it passes cam y, the cam 23 is locked in position such that it will withdraw the sets of pins 0 in their regular order, as by passing a bolt or pin through eye 3l on arm 25 into an opening 32 in the framework.

Thepinsoarewholly orpartially withdrawn by a fixed cam 33 as grooves m approach their cutting position and are released by said cam 33 in time to impale the new end of the web or webs. When collecting, the sheets on carrier C may be prevented from slipping as pins o are withdrawn by cam 33 by means of a feed-roller 34, which is journaled in arms 35, which arms in turn are journaled on the shaft of the adjacent roll Z. A spring-rod 36 (there may be one at each end of roller 34) keeps roller 34: in contact with carrier C, and roller 34 is flattened between its ends at 37, so as to avoid the lips at grooves m. The roller 3i,therefore,has disks at its ends which coact at all times with the cylinder' C, while the mutilated portion intermediate said disks permits the roller to pass the said lips without striking. Roller 34 is driven from the adjacent drawing-roll l, preferably at a slightly-higher surface speed than the carrier C, or the roller 34 may be driven from carrier C. Guides 3S maybe used to prevent sheets from blowing away from pins o.

When collecting, the end of the web (or webs) is impaled on a set of pins o, and the cylinder C is driven in the direction of the arrow thereon in Fig. 2, and shaft7and cam 23 are reciprocated in the manner above mentioned. The gear 5 is of a width such that the gear 6 is always in mesh therewith whatever be the position of the shaft? in its endwise movements, whence the cams 8 are revolved in all positions `thereof with respect to the fixed cam. Each set of pins ois withdrawn partially or wholly by the cam 33 and is released to impale the new end of the web as or just before the cutting occurs. Alternate blades w are rotated, and cam 23 withdraws the pins o ahead of said rotated blades, whereby collected sheets are folded off between rollers 22 by the described mechanism. The filler 2O is moved into cam y, and cams 8 are moved to inoperative position, so that the other alternate blades to will not be operated, and at the same times the cam 23 is moved into position such that it does not operate the pins o which at those times are passing it.

The folded products from rollers 22 may be delivered in any known and suitable manner.

The operation when folding successive cuts is obvious fromthe foregoing description, it being remembered that bolt-shaft 7 and cam 23 have no motion except rotation of the shaft during this operation and that both cams 8 and 23 are in their active or Working positions, so that each blade w is rotated every time it passes the cam y, and each set of pins ois withdrawn into the cylinder C every time it passes the cam 23. As above noted, the pins o may be drawn in partially only as they pass the cam 33, or they maybe wholly drawn in. The object of the drawing in the pins at this time is to prevent them from slitting the paper being laid upon the sheetreceiving surfaces of the carrier C. On the other hand, by drawing them in so that their sharp points barely protrude from the surface of the carrier or so that their points are within the cylinder C the pins make small holes in the paper as they are protruded later. Such later protrusion may take place as or after they reach the line of tangency between the paper and the cylinder. By only partially drawing in the pins when collecting, the sheet already on the carrier is held by the pins while the web of paper coming from the rolls Z is drawn tautly over the slightly-protruding pin-points, thus aiding in the piercing of the paper,while preventing tearing of large holes.

While I have shown mechanism adapted to collect two sheets or one less than the number of sheet-receiving surfaces on the carrier C, I am not to be understood as limiting myself to folding 0E one or two sheets, for by varying the size of the gears 5 6 and operating the cam 23 correspondingly more than two sheets may be collected and folded off.
