EDWARD P. SHELDON, OF NEW YORK, N. Y., ASSIGNOR. TO B. HOE AND 00., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

PRINTING-MACHINE.

Application filed July 17, 1912.

To all whom it may concern:

Be it known that I, EDWARD P. SHELDON, a citizen of the United States, residing at New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in printing machines.

Certain publications comprise what may be termed sheets printed in the ordinary way and specially printed sheets which are ordinarily termed inset sheets. The bulk of the publication is made up of sheets which may be printed on an ordinary high speed web press and which can be handled by the mechanisms usual in web presses. As a rule, however, the inset sheets require to be specially printed, that is, the plates or surfaces from which these sheets are printed, cannot be embodied in the same machine or at least on the same printing couples as the plates from which the web sheets are printed. In making such publications, therefore, it is usual to print the main part of the publication on a high speed web press and then assemble with the product of this press the inset sheets which sheets are printed on another machine, these sheets being necessarily handled by mechanism adapted to handle sheets as distinguished from mechanism which is adapted to handle web products even though in sheet form.

The present invention has for its object to produce an improved machine for making a publication consisting of web sheets and inset sheets such as referred to, which is comparatively simple and compact and which is capacitated to produce products which vary widely in size, the inset sheets being associated with the web sheets after the same have been collected, a cover being also included with the product if desired.

With this and other objects not necessary to specifically refer to in view, the invention consists in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed out.

Referring to the accompanying drawings: Figure 1 is a diagrammatic front elevation of one form of machine embodying Specification of Letters Patent.

Patented Mar. 16, 1915.

Serial No. 709,858.

the invention. Fig. 2 is a front elevation showing a part of the construction illustrated in Fig. 1, and certain sheet feeding and controlling devices operating in connection therewith. Fig. 3 is a diagrammatic view illustrating the operation of certain of the mechanism shown in Fig. 1. Fig. 4 is a view similar to Fig. 3, but illustrating a modified form of the construction.

Machines embodying the invention will include means for advancing webs which it will be understood have been printed on a high speed printing mechanism of ordinary type. In the particular construction illustrated, four webs are shown as coming in the machine over bending rollers l and nipping rollers 2, as usual in such constructions. The webs pass from the nipping rolls between a pair of cutting cylinders 3, 4 which severs the webs into sheets. The sheets then pass between guides 5, being forwarded through these guides by rolls 6 to a gollecting mechanism comprising cylinders The mechanism so far described is an ordinary and usual form of web press mechanism and requires no special description or illustration. It may be stated that the cylinder 8 is a three-part collecting cylinder and may be operated by the mechanism usually employed in the art for collecting either two or four cuts from the web sheets. In view of the well-known character of this mechanism the grippers and the operating devices therefor are omitted in the interest of brevity and clearness.

The driving mechanism of the parts so far described is generally indicated but it needs no specific description as it is well understood in the art.

The sheets are delivered from the threepart cylinder flat, a guide 10 being employed to assist in the delivery, if desired, to forwarding devices which also forward them flat. While these forwarding devices may be of any suitable character, in the construction illustrated they comprise a roll 11 with which cooperates a propeller roll 12, and a tape pathway 13. The roll which cooperates with the roll 11 for supporting the tape is not illustrated. The web sheets may be held down on the tapes 13, if desired, by any suitable mechanism, such, for instance, as a tape 14 running over a pair of pulleys, one of which is indicated at 15. A second forwarding pulley 16 may also be employed, if desired, this pulley cooperating with the pulley 15. It will be observed that in the machine illustrated the means by which the web sheets are advanced prior to collection comprises a vertically disposed pathway, and in the best constructions embodying the invention the webs and web sheets will, prior to collection, move through a substantially vertical pathway, as such construe tions conduce to compactness of the machine, rapid operation and ready accessi bility of the parts.

7 Machines embodying the invention will further include one or more sheet pathways which should be arranged at a substantial angle to the path of the web sheets before collection; constructions of this character again conducing to compactness in the machine and rapidity of operation. lVhile the pathways employed may be varied in number, vaccording to the number of inset sheets it is desired to include in the product, in the particular machine illustrated, two such pathways are shown, an upper pathway consisting of tapes 17, 18, and a lower pathway consisting of tapes 19 and 20. When the sheet pathway or pathways employ tapes, these tapes may be supported and operated in any suitable manner. In the particular construction illustrated, the tapes 18 run over driven rolls 21, and 23, a tightener 24 being employed, if desired. The tapes 17 pass over a driven roll 25 and a drop roll 26. In the particular construction illustrated, a drop roll 27 is also employed, this roll cooperating with the roll A tightener 28 may be employed in connection with the tapes1'7; The agencies for supporting and drying the tapes 19 and 20 are duplicates' of those already described, and the description thereof need not be repeated.

The tape pathways should have suitable timing devices cooperating with them, in order that the travel of the sheets therethrough may be properly controlled. While these'timing devices may be varied in construction, as illustrated they comprise stops 29, 29, the stops 29 being operated from a shaft 30 and the stops 29 from a shaft 31, these shafts carrying suitable cams and connections not necessary to specifically illustrate. In the best constructions embodying the invention, the devices for operating the timing devices will be of such a character that the time of operation of these devices may be varied for reasons which will hereinafter appear. In the particular construc-.

tion shown, the shaft 30 has secured thereto a plate 32 to which is bolted a driving gear 33. The shaft 31 is provided with a similar plate and gear. By disconnecting the plates the shafts may be turned to vary the time of operation of the cams thereon, and, consequently, the time of operation of the stops,

for varying the operation of the timing devices.

Machines embodying the invention will" include means for changing the direction of and superposing the sheets from the pathway or pathways upon-the collected web product while the same is flat. While these means may be varied, in the particularconstruction illustrated, they include a pair of cylinders 35, 36 which receive the sheets from the pathways. sheets passing through the pathway 17, 18 are directed by 'a guide 37 betweenia pair of forwarding rolls 38 and between guides 39. A second pair of forwarding rolls 40 further ac vance the sheet, and they are delivered between the cylinders 35,36 by a guide 41, a bent guide 4:2 and a roll 43 The sheets from the pathway 19, 20 are delivered be tween the rolls 35, 36. After passing between the rolls 35, 36, the sheets, in the particular machine illustrated, pass around the roll 36 and between it and propeller rolls 14, 15. In the particular construction illustrated, the sheets pass through a'guideway formed by guides 4:7, 18, the guide 4,8 being a bent guide, and around a roll 49, a propeller roll 50 being used in connection with this roll. After passing around the roll 19 the sheets pass between guides 51, 52, the guide 52 being a bent guide, which operate to deliver the sheets between the rolls 15, 16 where they are associated with and superposed upon the web sheets. V

N hen double length sheets are employed, the rolls 35, 36 may be operated as folding rolls, as shown in Fig. 3, in which case the roll 36 may be provided with'nipping jaws and the roll 35 with a tucking blade 54 which introduce the sheets between the jaws. The cylinder also may carry suitable sheet retaining devices, such as pins lVhen the rolls 35, 36 are to be employed as folding rolls, a double guide, as 57 may ad vantageously be employed in connection 7 therewith. When short sheets are being fed through, that is, sheets which are not to be folded, the jaws, pins and tucking blades are rendered inoperative and in that case a switch, as 58, may be employed to direct the sheets around the cylinder 36. 7 v

Fig. 4: illustrates a modified form of the construction in which the cylinders 35, 36

As illustrated, the 7 are employed as cutting cylinders, the cylblade 60 to pass this roll.

When the rolls 35, 36 are employed as cutting rolls, the roll 49 may be provided with pins, as 62, and a delivering switch or blade, as 63, so that this roll may operate to detain the second half of the cut inset sheet, thus giving time for the collection on the collecting cylinder which handles the web sheets. In other words, the sheet or sheets will be fed through the pathways and so timed in their movement therethrough that the first half of the sheet or sheets cut by the cylinders 35, 36 will be associated with and form an inset for one collection of sheets delivered from the collecting cylinder and the second half of the cut sheet or sheets will form an inset for the next collection of sheets from the collecting cylinder.

The other agencies used in connection with the modified form of construction shown in Fig. a are or nay be the same as those already described in connection with the construction illustrated in Fig. 3, and, therefore, need not be described.

It will be understood that the product consisting of the collected web sheets and the inset sheets associated therewith, will, as a rule, be folded in such a way that the inset sheets will form the inside pages of the publication. W hen this is the case, it may be desired to also provide the publication with a cover. While this may be done in various ways, in the particular construction illustrated, the cover is shown as being fed in over the cylinder 7 between guides 64, 65, tapes as 66 running over rolls 6?, 68 bein employed to advance the sheet between the guides, if desired. Suitable registering mechanism for determining the exact time of the passage of the cover over the cylinder '4' may be employed. In the particular construction illustrated, this registering mechanism comprises a front stop as 69, mounted on a shaft 70 also serving to support the guide 65. A propeller roll 71 is also shown, this roll coiiperating with the roll 7, to feed the cover forward when the front stop is raised. The cover will, of course, be timed to meet the collection on the cylinder 8 and properly registered therewith just prior to the time this collection is delivered fiat from the cylinder.

The machine which has been illustrated is capacitated to produce a very wide variety of products. Assuming, for instance, that four webs are being led into the machine, and two cuts from these webs are collected and forwarded flat, eight sheets or thirtytwo pages will be forwarded flat to the rolls 15, 16. Either a single short sheet or a double length sheet insert may be associated with this flat product, this depending upon whether a single short sheet or a double length sheet is fed through the sheet pathway to the cylinders 35, 36. Of course, if a short sheet is fed, the folding mechanism on the cylinders 35, 36 will be made inoperative. If, on the contrary, a double length sheet is fed, this folding mechanism will be rendered operative as shown in the drawings. A publication will accordingly be produced consisting either of thirty-six or forty pages, as the case may be, which pages may be further increased by the addition of a four page cover, if desired.

If four webs are being led into the machine and four cuts are collected, a much greater variety of products is possible, assuming, of course, that the machine is running at full speed, because more time is given to advance and control the sheets in the pathways. With a four out collection of web sheets, from a single sheet to afour sheet insert may be run to the cylinders 15, 16, according as to whether a single or double sheet is being advanced through the pathways, and also as to whether these sheets are simultaneously fed to the cylinders 35, 36, or one after another.

The machine will usually embody means for securing the sheets which form the publication together after they have been associated, and a stapling mechanism for this purpose is indicated at 72.
