HANS C. SCI-IROEDER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE GOSS PRINTING PRESS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SHEET-ASSEMBLING MECHANISM FOR PRINTING-PRESSES.

To all whom it may concern:

Be it known that I, HANS C. Sormonnnn, a subject of the German Emperor, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sheet-Assembling Mechanism for Printing-Presses, of which the following is a specification, reference be ing had to the accompanying drawings.

This invention relates to sheet assembling space saved but a more convenientand ac-' cessible form of such delivery mechanism is provided.

Other objects of my invention are to provide a new and improved form of sheet assembling mechanism in which a number of webs are gathered together and cut-intosheets forming the main body of the paper, in which insert sheets, after being fed to a suitable table, are folded centrally and thus folded are brought into association with the main sheets in position to be upon the inside of the folded product and in which cover sheets may be associated with the main sheets and insert sheets in such a position as to be on the outside of the-folding product.

Referring to the drawin s,-Figure 1 is a front elevation diagrammatically illustrating my invention Fig. 2 is a side elevation; and Fig. 3 is an enlarged detail, being a side elevation of the sheet folding and forwarding mechanism of the cover sheets. Referring to the several figures of the drawings, in which corresponding parts are indicated by like reference characters,-

4 indicates the main frame of the machine. 5 indicates the usual roller journaled in the main frame, over which the webs 67891011 are led. As shown in the drawings, there are six sections of the web. Of course, the number may be increased or diminished and it is immaterial whether they come from six separate webs or from one or more webs slit into sections in any well-known way. Passing over the Specification of Letters Patent.

Patented Dec. 31, 1912.

guide-rollers the webs pass over angle-bars 12 of the well-known form and description by which they are deflected and passin over suitable guide rollers as 13 are broug t together in registry and associated between registering rolls 14 in the well-known manner. Passing the registering rolls 14 in registry the webs pass between cutting cylinders 1516 where they are severed transversely in the well-known manner and are led between suitable guide-rollers as 17 to a collecting cylinder 18. The sheets severed from the superposed webs are collected upon the collecting cylinder 18 in any well-known and approved manner forming of itself no part of my invention. When a sufficient number are collected the lead edge is releascd from the grippers 19, with which the collecting cylinder is provided, after the lead edge has passed roller 20 and the sheets pass between guide-blocks 2122 downward and forward adjacent to gripper cylinder 23 to'be associated with the insert sheets as hereinafter described.

Referring to Fig. 2, where it is best shown, 24 indicates a suitable sheet forwarding mechanism, preferably such as that of the well-known Cross type, which is adapted to forward the insert sheets 25, which have been previously printed, in the well-known manner. The sheet forwarding mechanism 24 is, as is shown in Fig. 2, located within the main frame 4 and directly behind a fold ing and foiwvarding mechanism hereinafter described. One of these forwarding mechanisms is placed upon each side of the machine behind the folding devices hereinafter described, although only one is shown in Fig. 2 of the drawings to avoid unduly complicating the drawings. The sheets are delivered by the sheet forwarding mechanism 24, one at a time, and in a direction parallel with the run of the main webs 6 to 11, inclusive, into tape paths 2627 by which the sheets are fed one at a time forward upon a folding table 28 against a stop 29 between guiding ledges 30 (see Fig. 1). Actuated at suitable intervals by any well-known mechanism a folding blade 31 operates to tuck the central margin of the sheet fed upon table 28 between folding rollers 32 into tape paths 3334 by which the sheets centrally folded are fed down upon .a table 35 against the stop 36, which is adapted to be raised at suitable intervals by any well-known mecha- Applicationfiled February 17 1912. Serial No. 678 351.

. t REISSUED nism. At suitable intervals the gripper cylinder 23 engages the lead edge of the folded sheet and carries the same around 4 described, and located, as has been described above, directly behind the table and within the framework of the press.

37 indicates a folding tucking blade,

which, operated by mechanism, hereinafter described, at suitable intervals folds the,

sheet centrally in the direction of its run between folding rollers 38. By means of tape paths 3940 the folded sheet is led to a table 41 and brought against a stop 42, which will be hereinafter more fully described.

'43 indicates rollers above the table 41.

44 indicates a pressure roller adapted to co-act with roller 43 at suitable intervals and which is raised so as to co-act with roller 43 at suitable intervals in the manner hereinafter described. Whenever the rollers 43-44 are brought into operative relation and the stop 44 is removed at suitable intervals the sheets are fed into tape paths 45-46 and the parts are so timed that the lead edge of this cover sheet will be brought into registry with the lead edges of the main sheets and the insert sheets, brought together as above described, and below the main sheets' By means of these tape paths the associated insert sheets, main sheets and cover sheet are brought together upon a table 47 against a registering stop 48 from which they are folded by the usual folding blade as 49 operated in the well-known manner between folding rollers 50 to any suitabledelivery mechanism as delivery cylinder 51 and tape paths 52. The cover sheet-s may be of only one-half width transversely of their run in which case, of course, they will not be folded. In this case they are fed upon the left hand side (see Fig. 1) of the table 36. The folding blade 37 in this case acts to push the side edge of the sheet between rollers 38-39, the sheet being forwarded into the bite of rollers 38 by a movable pressure roller 53 (see Fig. 3) hereinafter described.

Referring to Fig. 3, 53 indicates a roller which is mounted upon arms 54 on a rockshaft 55 and is adapted, when the shaft is rocked as hereinafter described, to press upon the surface of the sheet when only a single width sheet is used for the cover as last above described. 56 indicates an arm on rock-shaft 55 which, by means of an arm 57, is operated by a cam 58 on shaft 59. lhe

cam 58 is so shaped as to move the arm. 57

to rock the shaft 55 at suitable intervals to bring the roller 53 int-o contact with the paper and coiiperate with the folding blade 37 as above described. Referring to the same drawing, the folding blade 37 is mounted upon an arm 78 on rock-shaft 79, which is rocked by arm 60 and link 61 operated by a suitable cam as 62 on the shaft 59. The cam is so arranged that the knife will operate at suitable intervals to forward the sheet whether folded or not folded to stop 42. The stop 42 is mounted upon an arm 63 on a rock-shaft 64 journalled inanysuitable way in a frame and provided with rockarm 65 which is operatedby arm 66 and cam 67 on the shaft 59. As is best shown in Fig. 3, the stop 42 is provided with a guide 68 which extends outward from the stop and bends downward and inward toward it suitable intervals to permit the sheet to be forwarded in time for its lead edge to come into registry with the main sheets and insert sheets as above described. The forwarding of the sheets at "suitable intervals when the stop is raised is effected, as stated above, by rollers 43 and 44, of which the roller 43 is fixed'and the roller 44 movable. As is best shown in Fig. 3, the shaft of the roller 44 is spring seated upon arm 69 on a rock-shaft 71. The rock shaft .71 is operated by another arm 72 and link 73 and cam 74 on the shaft 59. The cam 73 is so shaped and timed as to rock the shaft 71 and bring rollers 44 into operative relation with rollers 43 at such intervals as to forward the cover sheet into the tape paths 45-46 and meet the main sheets and insert sheets with their lead edges substantially together. That is to say, when all the sheets, the insert sheets, the

collected main sheets and the cover sheet are brought together at the lower side of delivery cylinder 23 into the bite of the tape paths 45 and 46 they are substantially in register and associated together. The registry is completed and the sheets brought into proper association for their final fold by being brought against the stop 48 as above described. A
