Application led April 27.. 1896. Serial No. 589,249. (No model.)

To al?, whom it' may concern;

Be it known that I, JOSEPH L. FIRM, a citizen of the United States, and a resident of Jersey City, in the countyof Hudson and State of New Jersey, have invented certain new and useful Improvements in Printing# Machines, of which the following is a specifi.- cation. i

In my Patent No. 556,409, dated March 17,

ro 1896, I described a printing-machine in which a mailing-,wrapper was combined and folded with the printed sheets in such a manner that one end of the Wrapper was caused to extend between the folds of the sheets. `As

describedin said patent, the sheets received two longitudinal folds before encountering the wrapper and the wrapper was laid 1ongitudinally on the sheets. The'sheets and wrapper together then received two trans# wrapper a third transverse fold. It is de'- sirable that the folds whereby the wrapper is combined with the sheets should be longitudinal folds-that is, parallel with the col.-

umns of printed matterand this is one of the objects accomplishable by my present.- inventou.

of the mechanism for treating the web after 3o being printed upon and, if desired, for applying the wrapper thereto. Figs. 2and Zaai-el detail views of the carrier B under one condiy tion ot adjustment. Figs. 3 and 3t are detail views of the same under another condition of adjustment.

the carrier rotating in the direction'of the arrow. Fig. 4 shows the same construction as Fig. l, with the omission of the superposing carrier C. Fig. 5 isa modification of Fig. -t in elevation. Fig. 6 is a plan of Fig. 5. Fig. 7 is au elevation'of the mechanism for applying and 4folding the wrapper. Fig. 8 is a modilicalion of the same, in which modicatiou the tape 38 is differently disposed.v Figs. 5 and 8 are taken on the sectionlines 5X and 8X, respectively, of' Fig. 6. Figs. 9, 10, andll show the action of the carrierDat-three ditlerentstages. Fig. 12 shows verse folds and then the projecting end'of the l Fig. 3b is a detail showing lie-3 lation of the diamond cam and folding-blade: as the coactiou of the same is commencing,A

` a detail of mechanism for adjusting the cut` ter-rollers Ltand 16. Figs. 13, 14, and 15 v. show three relative positions of thesheet and wrapper. Fig. 16 shows the positionv of the sheet, wrapper, and underneath supports at 55 the'instant of folding. Figs. 17, 18, and 19 show the three folds: of the wrapper. Fig.

20 shows a printing vvmechanism that may be used. The arrows on Figs. 2, 3, and 2a represent the vcarrier as rotating in the opposite v6or direction to that indicated bythe arrow in Fig. 1. Therefore yin Figs. 2, 3, 2a, 3, and 2b. the position of the rollers 15 16 and also of the rollers 4E 5 is reversed from that shown in Fig. 1. l i As described in patent to me, No. 415,321, 1 dated November 19, 1889, and in patent to me, No. 410,271, ldated September 3i, 1889, also as arranged in the printing mechanism shown in Fig..20 of the accompanying draw- 7o ings, the page-forms on the form-cylinders are arranged so'that the forms for those pages constituting the first half of the product (whether a book or a newspaper) are located uponcorrespondingzonesot'thevariousform- 75 cylinders, and the forms for those pages constituting the last half of the'product are ar- Figure 1 is an elevation, partly in section,

one another, as shown, without turning or `reversing the several pages belonging to the first half of the'product will arrange them- 85 selves abo ve each other and the several pages `belonging to the last half of the product will arrange themselves above each other side by side with those belonging to the first half. The longitudinal margin between the pages 9o constituting the Iirst halfand those constituting the last half of the product willl come in the middle. of thel folder A, Fig. 1, or on the line r,.so that the lineron which the rst longitudinal fold occurs will be in that niargin. Then the knivesA 19 on carrier B Will cut the web on themargin at the tops and bottoms of the pages, and the transverse fold made between the rollers 4 and 5 will be transversely across the middle of the pages. roo4 This system of collecting, cutting, and folding is fully illustrated in Figs. 1, 2, 3, and 4 of said Patent No. 410,271.

The web or webs are received from the printing mechanism shown in Fig. 2O onto the longitudinal folder A, whence they pass between the longitudinally-folding rolls 1 2 and receive their first fold. Thence they pass onto the carrier B, from which they are transversely folded between the rollers 4 and 5, the sheets being cut transversely from the web as they leave carrier B.

The construction of the carrier B and the mechanism carried by it is shown in detail in Figs. 2, 2, 3, and 3. It is fixed to a shaft d, to which is fixed the spur-wheel c, which drives the spur-wheel l). 6 and 7 are two shafts mounted longitudinally in the carrier B, near its periphery, on opposite sides of the center. Fixed to. each of these shafts are two inverse folders 8 9. Also fixed to each shaft are the inverse cam projections 10 11. Also lfixed to each shaft are the inverse arms 12 13, which are moved by a diamond'shaped cam 14, fast to the spur-wheel b. The position of this diamond-shaped cam may be either`- as shown in Figs. 2 and 2 or as shown in Figs. 3 and 3. It is adjustable from one position to the other at will by rotating the frame` 7c on the shaft d. The main frame l, in which the shaft d has one end bearing, is provided with the holesj and j', and the rotating frame 7c is provided with a hole c. When the rotating frame 7c is in the position shown in Figs. 2 and 2, it is held there by a bolt placed in the holesj and e. When in the position shown in Figs. 3 and 3, it is held there by a bolt placed in the holes j' and e. When the parts are in the position shown in Figs. 2 and 2, the shafts 6 and 7 and the parts carried thereby are inactive, excepting at the position shown. When the frame lc. is in the position shown in Figs.`3 and 3, the shafts 6 and 7 are inactive, excepting at the position shown. The folding- rollers 4 and 5 are so placed as to cooperate with 'the folding-blades when the same are operated at the point shown in Fig. 2. The folding- rollers 15 and 16 are placed on the opposite side of the carrier Bin the correct position to cooperate with the foldingblades when the same are operated in the position shown in Figs. 3 and 3. The -frame 7c carries a ring it', that overhangs both of the arms 12 13 and holds them in the position shown at the left of Figs. 2 and 2a or the right of Figs. 3 and 3 with the folding-blades inoperative throughout the whole rotation of the` carrier, excepting at the` point where the folding-blades are required to operate. For

this purpose at one point of the circumfer-` ence the ring 7c' extends radially outward into a pocket 7a2. This pocket is fixed radially Voutside of the diamond cam 14 and permits the arms 12 13 to be moved by said diamond cam into radial position. (Shown atrght of Figs. 2 and 2 and at left of Figs. 3 and 3.) The parts in the act of being so moved are shown in Fig. 21. With each of the doubl cams 10 11 is combined a lever 17, controlling theimpaling-pins 18. A spring 17, attached to eachlever 17, tends to hold each set of pins 1S outward, and said pins are retracted in opposition to said springs bysaid double cams 10 11, fast to the folding-blades. The timing is as follows In the construction shown in Fig. 2 the pins are normally held outward by the springs 17, and the forward edge of the web will be impaled on one row of the pins 1S as the same is passing the roller 4. which carries the matrix for knife 19. It will remain so impaled until the carrier has advanced about one-quarter revolution, whereupon the cams 10 11, acting simultaneously with the folding-blade, will move the lever 17 so as to retract the set of pins and release the edge of the web held thereby. As soon as the folding-blade has returned to its normal position the pins will be also returned to their normal outward position by the spring 17, The same operation is performed by the construction shown in Fig. 3, excepting-that lthe web is impaled against the roller-16, which in this construction carries the matrix. The same operation is also performed by the construction shown in Fig. 1, in which the web may be impaled either against the roller 4 and discharged to the right or may be iin paled against the roller 16 and discharged to the left. The arrows show the direction in which the carrier B turns.

19 19 are knives immediately preceding the impaling-pins and operating against the matriX 4 on roller 4 or the matrix 16 on roller 16, as the case may be, to cut the web transversely at the same instant that itis impaled on the pins. When the parts are adjusted in the position shown in Figs. 2 and 2, the parts shown at the left of the carrier Bin Fig. l are inactive and the web is folded between the rollers 4 and 5. When the parts are adjusted in the position shown in Figs. 3 and 3, the parts shown at the right of carrier 13 in Fig. 1 are inactive and the web is folded between the rollers 15 and 16, and in` order to hold the web onto the carrier in passing underneath it I provide a guide 20.

By the constructions and adjustments above described the operator is enabled to either send the web to the mechanism at the left of carrier B in Fig. 1, whereby it is delivered with one transverse fold, or he may send it to the mechanism shown at the right of thev carrier B in Fig. 1, whereby it is treated in the manner hereinafter more particularly set forth.

The sheets pass from the rollers4 5 between the guides 21 and 22 to acari-ier C. are then gripped by the grippers 23 and carried around the carrier C, and thereby superposed upon the next succeeding sheets, so that every twof longitudinally and transversely folded cuts from the web are superposed on each other. The mechanism mounted upon the carrier C, by which this is They atasco a accomplished, is well known,and therefore need not be particularly described. One form' which will answer the purpose is described in my Patent No. 415,321, dated November 19, 1889. The superposed cuts from the web are received by the gripper-belt 24,

which is carried by the sprocket-wheels and 26 into position to be combined with the wrap per-web, or the carrier C may be omitted and tapes 24a, extending around the rollers 5 and 26, may be substituted for the gripperbelt 24, so as to carry each cut without superposing directly from the folding-rollers 4 5 to the position for combining with the wrapperweb E, as shown in Fig.

The Wrapper-web E proceeds fromi its roll past the guide-roll 27 and over the folding- -roller 28, where its forward endis impaled,

as shown in Fig. 9, upon impaling pins 29, carried by a carrier D. It remains thus impaled until the impaling-pins 29 have advanced to the position shown in Fig. 10, where it is stripped from t-he impaling-pins bythe stripper 30, so that it then lies horizontally across the rollers 28 and 31. Thereupon the folding-blade 32 of the carrier D folds it transversel y between the rollers 28 and 31, as shown in Figs. 11, 8, and 9. As the knife 33 passes the roll 28 it will cut the wrapper-web transversely at the proper distance from its fold. Duplicate sets of pins, knives, and folding-blades are carried by the-carrier D, so as to produce the above-described operation twice for each revolution of such carrier.

As the web E is being pinned, stripped, folded, and cut by the mechanism on carrier D a printed sheet from web A', folded longitudinally and transversely, is brought into position by the gripper-belts 24 or bands 24a against stop7 so as to be folded longitudinally between the rollers 28 and 31 inside the wrapper atthe same time that the wrapper E is folded transversely.

31a is a fixed guide to assist the belts 24 in supporting the sheet above the roller 31.

In order to explain the timing as between the travel of the sheet and of the wrapper, I will refer to Figs. 13, 14, and 15. In Fig. 13 the sheet A' and the Wrapper E are advancing in the directions of the arrows and occupy substantially the relative positions shown when the wrapper is impaled by the pins on carrier D, as shown in Fig. 9. In Fig. 14 they have advanced farther and now occupy the position where the wrapper is stripped from the pins, as shown in Fig. 10. In Fig. 15 they have advanced still farther and now occupy the posit-ion for folding, as shown, the fold being made, as shown in Fig. 11, upon the line ai a: and the transverse cut of the wrapper being subsequently made on the line y y. Fig. 16 shows the same position as in Fig. 15, with the addition of the folding-rollers 28and 3l and the belts 24, by which the sheet and wrapper are supported from below at the iustant the folding commences, the sheet being on top o'f the wrapper and the wrapper beingV below the belts 24. By timing the movement per and sheet occupy such position that theV fold is longitudinal of thesheet and transverse of the wrapper, so that the two succeeding folds necessaryfor the application of the wrapper may be made also longitudinally of the sheet and therefore in the most desirable position with respect to the columns of the sheet. Y,

After the wrapper and sheets have received their rst fold together -they areas shown in Fig. 17,` (in which figure forclearness ofv illusf tration the folds of the sheet previous 'to its union with the wapper are omitted,) and the tially across the other side. This represents the product as it emerges from `folding- rolli ers 28 and 31. By the mechanismshown in Figs. '7 and 8 the product is next folded parallel with the fold @om on the line e' z, Fig. 17, into the form shown inFig. 18, and next the projecting iiap of the wrapper,fafter being supplied with paste, is folded on the line w w into the position shown in Fig. 19, when the product is completed.

The form of construction shown in Figs. 5, G, and 8 may be described in detail asrfollows:

The carrier B and folding-rollers 4 and-5 are as described in connection with Fig. 1. The longitudinal-folding rollers 1 2 arearranged so that the longitudinally-folded web descends vertically tangent to the carrier B, being received between the carrier B and the tape and held onto the carrier until it reaches the folding- rollers 4 and 5, between which it is transversely folded. Thence it passes over the guide 22 onto the gripping-belts 24, which and the remainder of the mechanism, are of substantiallythe same construction as before described. In Fig. 6 the mechanism for driving the various parts is shown. Supposing the gear 100, fixed on the shaft of carrier B, to be the prime mover, it drives the gear 107, fixed on the shaft of roller 2, which in turn drivesv the gear 106, xed on the shaft of roller l. The prime mover 100 also drives the gear 108, from' which the. .folding- rollers 4 and 5 are fixed on the roller 25by whichthe gripperbelts 24 are driven. .The power Vfrom the prime-mover shaft is comm'unicatedthrough -the beveled gears 101 102 and the shaft 111 of the carrier F to the gear 103. AThis gear drives the gear 104, Xed to the shaft of the roller39. The gear 104 drives the gear 105,

IZO

driven, andthe gear 10.8 drives thegear 109,

90 wrapper lies, as shown in said vfigure, transversely of the printed columns, extendingentirely across one side and a distance beyond the edge and around the fold mx and par- D, the folding- rollers 28 and 31, the folding- rollers 36 and 37, and the folding- rollers 42 and 43 may be driven by suitable gears (not shown) from the gear 103. The lcarrier 112 and delivery-table 113 (shown in dotted lines in Fig. 5) are similar to the corresponding parts shown at the left of Fig. 1 and would only be used in case the carrier D and succeeding mechanism should be dispensed with or moved out of position.

Referring nowv to Figs. 7 and 8, the product shown in Fig. 17 passes from the rolls 2S 31 between the belts 33 and 34, wherebyitis carried to the grippers 35 on the cylinder F and carried forward thereby until folded between the rollers 3G and 37 by the folding-blade 46, operated by any suitable mechanism on the carrier F. After the product shown in Fig. 1S passes from the folding- rollers 36 and 37 it is carried by the tapes 34 and 38 past pasting-roller 39 (by which the paste is applied to the projecting end of the wrapper) to carrier G, where it is gripped and held by the gripper 41 until folded by the foldingblade 47 between the folding- rollers 42 and 43, where its last fold is received parallel with the two preceding. I t is then dropped between the guides 44 and 45 into the box II completed, as shown in Fig. 19.

In Fig. 12 I have shown a convenient form of adjustment for the bearings of the rolls, as 4or 16, which carry the knife cutting-blocks. Each journal 50 of the roll is mounted in a block 51, sliding on the frame 52 and held in adjustment between the set-screws 53 and 54. By means of this adjustment both of the rollers containing the matrices which coperate with the carrier-knives may be adjusted s0 as to bring either or both of said matrices int-0 coperative contact with said knives,as shown in Fig. 1. In case both matrices are brought into use the paper will be transversely cut twice for each rotation of the carrier, or either of said matrix-carrying rollers may be adjusted away from the carrier, so that the knives will form coperative contact with only one matrix for each revolution of the carrier. This feature of adjustment is additional to anything shown in my Patent No. 556,409 and greatly enlarges the scope of the Work which may be done upon the machine. Of course only one of the two sets of folding mechanisms will be in use at the same time, one being designed for use when the papers are to -be wrapped separately for mailing and. the

other when they are to be simply folded.

The printing mechanism shown in Fig. 20 may be described as follows: The webs a a' a2 go to make up the composite web A', being printed on, respectively, by the three printing mechanisms b b b2. Each printing mechanism consists of a pair of impression-cylinders 61, close togeth erin the middle, with a formcylinder 62 and 63 on each side. The inking mechanism 64 and 65 is arranged on the outside of each form-cylinder. All the form-cylinders are parallel with each other, and the' cylinders in each printing mechanism are arranged in a horizontal row. The corresponding cylinders inthe different printing mechanisms are arranged in vertical planes. Each web is led into this, its printing mechanism, from a guide 66 above and out of its printing mechanism, to a guide 67 below. Thence they pass to the guides 68, 69, and 70, thence upwardly to the guide 71, and thence together onto the folder A.

I believe that by this invention for the first time a wrapper is brought onto a sheet by being fed transversely of the sheet and the two folded together longitudinally of the sheet.
