SHEET-HANDLING MACHINE.

Specification of Letters Patent.

Patented Au. 5, 1919.

Application filed October 12, 1915. Serial No. 55,397.

To all 'whom #may concern:

Be it known that I, SAMUEL G. Goss, a citizen of the United States, and a resident of Glencoe, Illinois, have made Improvements in Sheet-Handling Machines, of which the following is a specification.

The invention relates to machines for handling sheets, and more particularly to machines for cutting sheets from a web running from a printing press, or like machine, and forwarding them to a collecting l cylinder or like device, the collected sheets usually being forwarded to a folding meehanism, with or without the intervention of a stitcher. The objects of the invention will in part be set forth hereinafter, and in part will be obvious herefrom.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements `herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention, and together with the description serve to explain the principles thereof.

Of the drawings z*- Figure 1 is an elevation of a machine constructed in accordance with the principles of the invention Fig. 2 is an end elevation looking at Fig. 1 vfrom the right;

IFig. 3 is a view, partly diagrammatic, showing one position of the mechanism and one stage in the cutting and forwarding of the sheets; and

Fig. l is a view similar to Fig. 3, but

showing the mechanism and material in a different position.

done by rotary cutters severing successive sheets from the running web, and the cut sheets are collected or superimposed one on the other by means of a collecting cylinder.

A usual form of collecting cylinder has spaces upon its periphery for three sheets in succession thereabout, while the printing or form cylinders of the press have the plates arranged with four pages around the cylinder. During the operation of the machine, consequently, the fourth printed sheet is superimposed on the first sheet on the collecting cylinder, and so on, until a complete set of the printed sheets is built up on one of the sheet spaces upon the collecting cylinder. The same process or procedure, of course, will be in progress, although in different stages, at the other sheet spaces on the collecting cylinder. When a set of sheets is completed upon one vof the sheet spaces of the collecting cylinder', it is deflected or stripped ofl:1 and is forwarded to stitching or folding mechanism, or to both, operating either successively or simultaneously.

The sheets are taken and held upon the collecting cylinder by suitable means, such as grippers, the grippers opening to receive the successive sheets fed or forwarded thereto, and then opening to release the complete set of sheets which go forward through the machine. The periphery of the collzecting cylinder is suiliciently large, preferably, to take the sheets arranged thereabout and to provide therebetween space for the gripper mechanism. By such an arrangement there is no interference between the tail of one sheet and the head of the next, nor is there smndging of the tail of the sheets by the moving grippers, as would be the case where the periphery of the collecting cylinder is in integral ratio, or is precisely equal in length to three sheet lengths, in which case the grippers would have to be beneath the tail of a sheet and would have to lift it each time they operated to take a new sheet or to release the sheets.

Where the collecting cylinder periphery is larger than the precise ratio to the sheet length, that is, when proper gripper space of thatY cylinder. 15

is provided in the periphery of the collect-V ing cylinder between the successive sheet spaces, the collecting cylinder must travel faster, that is, have a greater peripheral speed than the web and Web supplying means, in order to bring the heads of the successive sheets to the successive grippers.

It is very desirable and necessary in highV class work that Vthe superimposed sheets uniform superimposing of the sheets at a high speed, one of the prime objects of this Y class of machines being to secure a very high class of printing at highV running speeds.

' Referring more particularly to the drawings, illustratingby way of example, one

embodiment of theinvention, a perfected" web from which the sheets i areV cut is shown at the top of Fig. 1 running in from the printing press or likeinachine. The web is shown ruiming between rolls 1 and 2, which may be driven pinch rolls or disks, or they may be tape 'carrying rolls or disks, or other form of web supplying means.

. The sheets are severed from the ruiming web in a suitable manner, and in the embodied Vform rotary opposed, cooperating cutters are provided. In said sheet cutting means, a shaft 3 is journaled in the machine frame, said shaft ,carrying a plurality of cirn cular disks and a webor webs 5 extending longitudinally betweenthe disks. Mounted Y on theweb 5 is a Vshearing knife 6. Y YIn the embodied form, the cuttersare double and a secondV web, or series of webs 7 ,similar to theV web V5 are carried by shaft 1 Vand disks 4c. A yshearing blade 8 is'mounted on the web 7. Y

Opposed to, and'coperating with, this mechanism, is asimilar mechanism on Vthe opposite'side'of the web, comprising a shaft 9 mounted inthe machine frame and having Y. Y disks 10 and webs 11 and 12, carrying, re-

spectivelyg, shearingblades 13 and la.V Suitable gearing and coperating driving means V(not shown) are provided for these cut-ters ning webV after a sheet has been cut,and for feeding on the sheet until it is to be speeded up to be taken by the collecting means, thereV are'pro'vided rotary coperating 'devices act-VV ing on both sides of the W eb or sheet. A shaftA 15 is rotatably mounted inthe machine frame, and a plurality of circular disks 16 arecarriedfupon the shaft. The disks 16 are interrupted, as shown at 17a, that is, they have a depressed` portion whichv does not engage the sheet, said devices constituting an embodiment of intermittently or alternately operating sheet gripping'and releasing means.

, The cooperating mechanism is substantially'the saine, as embodied, comprisingra( shaft18 having a plurality of circular disks 19, the disks having depressed portions 25. When the proud portions of' the opposed disks 16V and 19 are passing the path of travel of the sheets, they grip the sheets and feed Vthem forward, but whenthe low'parts 1'7" sheet pathway, the Y and 25, are passing :the sheet is released. 'l

For the purpose` of guiding and keeping the sheets in theirpath of travel, guide bars 2O are provided, preferablyextending above and between theV disks 16 and 18, and downwardly between disks or rolls 31 and341'and into close proximity to the collecting cylinder. The guides 20 are mounted onv a rod22 supported on the machine frame.- On thev opposite side of the sheetpathway are like guide bars 21 mounted on a rod 23, carried by the machine frame. The sheets pass along between the two series of bars V20- and 21.

In the embodied form of means for speeding up the sheets tothe speed of the collect! ing cylinder, opposed series of cooperating disks are provided, generally similar totheVV seriesof disks 16 and 19. In suchembodied form, a shaft 30 is mounted in the machine frame. Upon shaft 30 isfmounteda series of circular disks 31, having a proud part for engaging and feeding the sheets and a low part 32 for releasing'the sheet. i

The opposed and oo perating mechanism comprises a shaft 33 mounted in theV frameV of the machine and carrying a series of circular disks 34, having a proud, sheet engaging part and a low part 35. The disks 16 and 19 are running atthe speed of the web supplyV while the'disks 31 vand 34C are running at the ff f speed of the collecting cylinder. Thefdisks l6'and -19V release Ythe sheet just as it is gripped and begun to be fed Yforward by the f disks 31 and 34. Y

The embodied sheet collecting device is the collecting cylinder 35 already referred to and briefly described. The cylinder 35is Vmounted in a'shaft 36 journaled in the mavchine frame.V The three sheet carrying spaces upon the peripheryof lthe cylinder are indicated as 40, Z11 and 12, and the grippersas 37, 38 and 39.5.These grippers open and close to takej on successively the successively `fed and subsequently superimposed Lon the other side'vof the sheet, as embodied, l'

sheets'whi'ch make up the bodyof the pam-vf.

phlet. As previously stated, the periphery of the cylinder 35 is greater than the three sheet lengths by the space required for the three sets of grippers 37, 38 and 39 andthe collecting cylinder has a correspondingly greater peripheral speed than the web supply, the-sheet cutters and the feeding disks 16 and 19. The grippers are shown somewhat conventionally, but the details of the mechanism are known and will be understood.

' Suitable means for receiving the collected sheets are provided,`and as embodied, the collected group of sheets is deflected into a tape pathway by a stripper device 43. Bottom tapes 44 are shown running over rolls or disks 45 and top tapes 46 are shown running over rollers or disks47. The sheet groups or bundles may be conveyed to a folder or a stitcher or both, or forwarded or delivered in some other suitable manner.

The operation of the mechanism will be understood from what has been said, the webI running in from the press, and the double rotary cutters cutting off two sheets for each rotation thereof, as shown in Fig. 3. The disks 16 and 19 feed the sheet onward until it is engaged by the front edge of the proud part of the disks 31 and 34. When so engaged the sheet is released by the low part of disks 16 and 19, as shown 1n Fig. 4. It is now traveling at the speed of the collecting cylinder and is delivered into the grippers thereon, as the lower sheet is shown in Fig. 3. The front edges of the proud parts of disks 16 and 19 engage the oncoming end of the web, as shown in Fig. 4, and feed it on, the next sheet being cut by the next set of cutters, as shown in Fig. 2, and so on.

Itxwill be understood that a machine has been provided embodying the advantages and features of invention pointed out and explained, as well as other features and advantages which will be understood.

The invention in its broader aspects is not limited to the mechanisms shown and described, but changes may be made therein, within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
